The findings come from an unusually direct test of a widely discussed personality trait. Environmental sensitivity, often marketed in popular psychology as the hallmark of the highly sensitive person, is defined as a tendency to feel the effects of both positive and negative experiences more deeply than others do. Highly sensitive individuals are thought to react more strongly to stress and adversity while also drawing greater benefit from supportive relationships and uplifting experiences. Previous work has even linked the trait to genetics: a study of nearly 2,900 teenage twins found that heredity may account for almost half of the variation in how sensitive people are to their surroundings.

But most of that earlier research concentrated on dramatic life events: childhood experiences, trauma, major transitions. Lead author Kim Meidenbauer, an assistant professor of psychology at Washington State University, and her colleagues wanted to know whether heightened sensitivity also extends to the ordinary physical settings people move through every day. To find out, they analyzed more than 3,800 surveys completed by Chicago residents who used a smartphone app to record their emotions in real time and rate the conditions of the outdoor neighborhoods and parks they were visiting.

The results were striking in what they did not show. There was no evidence that the personality trait amplified emotional responses to physical conditions such as air quality, temperature, or noise. A highly sensitive person sweltering on a hot sidewalk or walking past a smelly alley reported essentially the same emotional reaction as anyone else facing the same conditions. The trait simply did not act as an amplifier for the physical world.

What the researchers did find was a powerful social signature. Perceived safety, orderliness, and friendly interactions among nearby people were far more strongly associated with positive emotions in highly sensitive participants than in their less sensitive counterparts. A street littered with trash or covered in graffiti triggered a greater sense of unease in these individuals, while a neighborhood where people greeted each other warmly provided a stronger emotional boost. The sensitivity, in other words, was tuned to human signals rather than to thermal or acoustic ones.

That distinction raises uncomfortable questions about what the standard questionnaire used to identify the trait is actually measuring. If highly sensitive people are not more reactive to physical environments, the instrument may be capturing something closer to social and emotional attunement than to a general responsiveness to surroundings. Scientists, Meidenbauer suggests, may have been measuring a different kind of sensitivity than the name implies, and the popular label of environmental sensitivity could be actively misleading.

For the many people who identify as highly sensitive, the findings carry a reassuring message. Having the trait does not necessarily mean bracing for a stronger emotional response to every aspect of one’s surroundings. As Meidenbauer put it, it seems to be more about social environments than the physical environment. Someone with the trait can walk down a loud, uncomfortable street without expecting to be overwhelmed, provided the social atmosphere feels safe and welcoming.

The researchers are careful to note the limits of their conclusions. The study examined everyday conditions, not extremes. Meidenbauer cautioned that the results do not rule out stronger reactions to dangerous heat, severe air pollution, or other genuinely hazardous conditions, where heightened sensitivity might still play a role. Her laboratory is now investigating whether other personality traits and individual preferences for hot or cold weather can better explain why people respond differently to the same environmental conditions, a line of inquiry that could untangle the confounds the current study exposed.

The broader implication is a reframing of what it means to be highly sensitive at all. Rather than experiencing everything around them more intensely, highly sensitive people may simply be more affected by the human experiences that make a place feel welcoming or threatening: the warmth of strangers, the order of a public space, the visible signs of care or neglect in a neighborhood. If future research confirms this pattern, the trait may need a new name, and the growing community of people who identify as highly sensitive may gain a more accurate understanding of the gift and the burden they actually carry.

The researchers focused on a cognitive function known as response inhibition, the capacity to suppress an action that has already been set in motion. Response inhibition is a core component of executive functioning, the family of mental abilities that also includes planning, working memory, and cognitive flexibility. When inhibition fails in everyday life, the result can be impulsive aggression, risky decision-making, or the inability to stop oneself from acting on a fleeting urge. Previous meta-analyses have established that people high in psychopathic traits tend to perform worse on inhibition tasks, but far less was known about how sadism relates to this same capacity, and almost nothing was known about how the two traits compare when the stimuli in question are emotionally charged rather than neutral.

To probe this question, the team used a go/no-go task, one of the most widely used paradigms in cognitive psychology for measuring inhibitory control. In this task, participants are presented with a rapid stream of images and instructed to respond quickly to certain categories of stimuli while withholding their response to others. What made this version distinctive was its emotional content: the stimuli were photographs of facially expressed emotions, drawn from four categories that Paul Ekman’s classic work identified as universal: happiness, sadness, anger, and fear. Faces are a particularly revealing class of stimulus because they carry rich social and affective information, and both psychopathy and sadism have been theorized to involve abnormalities in processing exactly this kind of signal.

The task yielded three key performance measures. Commission errors occurred when participants pressed the button even though they should have withheld their response, a classic sign of failed inhibition. Omission errors occurred when participants failed to respond to a stimulus that required a response, which can reflect lapses in attention or difficulties in recognizing the emotional category of the face. Reaction time, finally, captured how quickly participants responded when they did press the button, providing a window into the speed of their processing. By analyzing all three measures together, the researchers could distinguish between different underlying deficits that might otherwise look identical in the data.

The first round of analysis was deliberately simple. In bivariate correlations, both psychopathy and sadism were positively associated with both types of errors, meaning that people higher in either trait made more mistakes of both kinds on the task. Psychopathy, however, showed a negative association with reaction time: the more psychopathic the participant, the faster they responded overall. At first glance, this pattern makes the two traits look alike, echoing the concerns raised by researchers who have argued that psychopathy and sadism scales may be measuring the same thing. But the similarity dissolved once the authors moved to analyses that could separate the unique contribution of each trait.

Using canonical correlation analysis, a statistical technique that examines the relationship between two sets of variables simultaneously, and then a structural model that allowed psychopathy and sadism to compete as predictors of the same task outcomes, the picture changed dramatically. Psychopathy positively predicted commission errors, indicating decreased response inhibition and, plausibly, lower accuracy in recognizing the emotional expressions themselves. At the same time, psychopathy negatively predicted reaction time, meaning that individuals high in psychopathic traits were not slower but faster than average. Sadism told a different story entirely: it positively predicted omission errors, pointing toward potential attentional deficits, and it marginally positively predicted reaction time, suggesting slower rather than faster processing of the emotional faces.

These divergent signatures are more than statistical curiosities; they speak to fundamentally different psychological mechanisms. The psychopathy profile, marked by impulsive commission errors combined with rapid responding, is consistent with a long line of research on response modulation in psychopathy. According to influential models developed by Joseph Newman and colleagues, individuals with psychopathic traits show early selective attention abnormalities: they focus so narrowly on goal-relevant information that peripheral emotional signals fail to modulate their behavior, allowing them to barrel forward regardless of the affective consequences. The fast reaction times observed here fit neatly with this account of a quick, emotionally underdamped processing style that barrels past inhibitory brakes. The finding also echoes meta-analytic evidence that psychopathy is associated with pervasive deficits in recognizing facial and vocal emotional expressions, particularly fear and sadness, a literature going back to Blair’s foundational studies of reduced sensitivity to others’ fearful expressions.

Sadism, by contrast, produced a pattern suggestive of slowed, attentionally compromised processing rather than impulsive speed. The positive prediction of omission errors implies that highly sadistic participants sometimes failed to register or respond to the emotional faces at all, while the marginal slowing of reaction times hints that when they did respond, they took longer to do so. This is consistent with earlier work by Međedović showing aberrations in emotional processing of violence-dependent stimuli as a core feature of sadism, and with studies linking everyday sadism to blunted startle reactivity. Where the psychopathic individual may race past emotional information, the sadistic individual may linger in a state of attenuated, inefficient engagement with it, a difference that could reflect different motivations for causing harm: impulsive instrumental exploitation on one side and a more deliberate, attention-grabbing preoccupation with others’ distress on the other.

The authors also made a methodologically important decision about how to measure psychopathy. Many psychopathy inventories include a lifestyle facet characterized by impulsivity and disinhibition, and it is this facet that shows the strongest associations with inhibition in the existing literature. But, as the researchers note, that association is largely tautological, since a disinhibition trait is by definition a lack of behavioral control. Including it alongside other psychopathy facets would risk crowding out predictors with genuine explanatory value. Instead, the team used the Psychopathic Personality Traits Scale, which separates psychopathy into a lack of cognitive and affective empathy, manipulation, and egocentricity, components that conceptually align with the Dark Triad of psychopathy, Machiavellianism, and narcissism. The results may therefore have implications for dark personality traits more broadly, suggesting that the emotional processing signature of psychopathy is carried by its interpersonal and affective core rather than by its impulsive periphery.

The study is not without limits. The sample was drawn from a general rather than clinical or forensic population, so the traits were assessed at subclinical levels, and the go/no-go task, while well validated, captures only one slice of the complex interplay between emotion and cognitive control. Nonetheless, the implications are considerable. For clinicians and forensic professionals, the results suggest that psychopathy and sadism should not be treated as interchangeable constructs when assessing risk or designing interventions: a fast, inhibition-impaired processing style calls for different management strategies than a slow, attentionally deficient one. For personality science, the findings push back against recent claims that psychopathy and sadism scales are redundant, demonstrating that the two traits dissociate cleanly at the level of objective behavioral performance. And for anyone intrigued by the dark side of human nature, the study offers a vivid illustration of a broader principle: two traits can wear the same mask of callousness while operating on entirely different machinery underneath.

The study, published as an open access paper in Discover Psychology, was led by Denis Javier Muñoz with colleagues including corresponding author Miguel Landa-Blanco. It set out to test three candidate explanations for psychological desensitization to violence: the sheer amount of violence a person has witnessed or experienced, a tendency to process information in negative or threatening ways, and the cluster of socially aversive personality traits known as the Dark Triad, comprising Machiavellianism, narcissism, and psychopathy. Honduras, with its long history of gang activity, homicide, and community insecurity, offered a setting where such questions are not abstract but part of everyday life.

Desensitization to violence is not a single psychological state. The researchers treated it as a multidimensional construct with four distinct components: emotional habituation, meaning a reduced emotional reaction to violent events; justification of violence, meaning the belief that violent behavior can be legitimate or warranted; indifference toward victims, meaning reduced sympathy for people harmed by violence; and social naturalization, meaning the perception that violence is a normal, expected part of the social environment. This distinction matters because the drivers of each facet may differ, and interventions designed to blunt one form of desensitization may do nothing for another.

The sample consisted of 328 Honduran adults, roughly seventy percent of whom were women, with an average age of about twenty-six years. Participants completed measures of violence exposure, negative cognitive processing bias, Dark Triad traits, and the four desensitization dimensions. The research was approved by the Research Ethics Committee of the Faculty of Social Sciences at the National Autonomous University of Honduras in June 2025, conducted in accordance with the Declaration of Helsinki, and all participants gave informed consent with anonymity maintained throughout.

Methodologically, the team took an approach that many psychology studies still lack. They built four hierarchical regression models, one for each desensitization dimension, entering sociodemographic covariates first, then negative cognitive processing bias, then violence exposure, and finally Dark Triad traits. This ordering allowed them to see whether each block of predictors explained desensitization beyond what the earlier blocks already accounted for. Crucially, they used HC3-robust standard errors, a technique that protects significance tests when the data violate the tidy assumptions of ordinary regression, such as when residual variance is uneven across levels of a predictor.

The statistical caution did not stop there. Because the four final models together contained sixty coefficients, the researchers applied a Bonferroni correction across all of them, drastically lowering the threshold for declaring a result statistically significant and thereby reducing the risk that any single finding was a false positive. They also imposed a smallest-effect-size-of-interest threshold, a modern open science practice that asks not merely whether an effect differs from zero but whether it is large enough to matter in the real world. Effects falling below that floor were not treated as meaningful, no matter how statistically detectable they were.

What emerged after this gauntlet was a strikingly short list. Male sex was associated with three of the four dimensions: emotional habituation, justification of violence, and indifference toward victims, with standardized coefficients of roughly 0.24, 0.20, and 0.22 respectively. Machiavellianism, the Dark Triad trait characterized by strategic manipulation and a cynical view of human nature, was associated with justification of violence and indifference toward victims, showing the strongest coefficient in the entire study at approximately 0.42 for justification. Exposure to street or neighborhood violence was associated with social naturalization, with a coefficient of about 0.24. Everything else, including narcissism, psychopathy, and the entire negative cognitive processing bias hypothesis, failed to survive the global correction.

The implications of that pattern are worth unpacking. The finding that Machiavellianism predicted justification of violence and victim indifference, but not emotional habituation or social naturalization, suggests that this trait is tied specifically to the moral and interpersonal dimensions of desensitization rather than to blunted emotional reactivity per se. Meanwhile, the link between street violence exposure and social naturalization fits an intuitive picture: people who regularly encounter violence in their surroundings come to see it as an ordinary feature of community life, without necessarily endorsing it or losing sympathy for its victims. Male sex emerging as a correlate of three dimensions echoes a broad literature on gender and aggression, though as a cross-sectional correlate it cannot explain why the gap exists.

Equally notable is what did not appear. Negative cognitive processing bias, the idea that people who habitually interpret ambiguous information in threatening or negative ways become more accepting of violence, received no support in the final models. The authors themselves are explicit that the hypotheses concerning violence exposure and Dark Triad traits earned only partial support, and that the findings identify a limited, dimension-specific set of correlates. They also caution that the study is cross-sectional, meaning all variables were measured at a single point in time, so nothing here can be read as causal. It is entirely possible, for instance, that desensitization changes how much violence people notice or report rather than the reverse.

For a country where community violence remains a pressing public health concern, the study offers both a sobering lesson and a practical one. The sobering lesson is that simple exposure-based narratives, in which seeing more violence mechanically numbs people to it, capture only one narrow facet of the phenomenon. The practical one is that any prevention or intervention program aimed at reducing tolerance for violence in Honduras may need to target different mechanisms for different outcomes: addressing Machiavellian manipulation and moral disengagement where justification of violence is concerned, and tackling the normalization of violence in neighborhoods where it has become part of the social fabric. As the authors emphasize, these are correlates, not causes, but in a setting where every data point is hard-won, even a short list of survivors after rigorous correction is a finding worth taking seriously.

The instrument in question is the Big Five Aspect Scales short version, known as the BFAS-40. The original Big Five Aspect Scales, developed by Colin DeYoung and colleagues, grew out of the observation that each Big Five domain splits into two aspects: for example, extraversion divides into enthusiasm and assertiveness, while neuroticism splits into withdrawal and volatility. These aspects sit between the broad domains and the even narrower facets measured by instruments such as the NEO Personality Inventory, and they have proven useful for linking personality to psychopathology, political ideology, and well-being. The BFAS-40, developed by Gallagher, Stevenor, Samo, and McAbee, condensed the original longer scales into just four items per aspect, aiming to preserve psychometric strength while cutting completion time dramatically.

Translating a questionnaire is not simply a matter of swapping words. Personality items often rely on idioms, subtle emotional vocabulary, and response conventions that do not map neatly across languages. Italian researchers have a long history of adapting personality measures, going back to factor-analytic work on the NEO inventories in the 1990s and 2000s, but each new instrument must be validated on its own terms. A team led by Chloe Lau of the University of Toronto and Francesco Bruno of Universitas Mercatorum in Rome, together with Francesca Chiesi of the University of Florence and Lena Quilty of the Centre for Addiction and Mental Health, took on that task for the BFAS-40, testing the translated scale in a community sample of 662 Italian-speaking adults.

The methodological heart of the study is its use of multidimensional item response theory, or MIRT, a modern statistical framework that models how each individual item functions across levels of the underlying trait. Unlike classical test theory, which focuses on total scores, item response theory estimates parameters for every question: how well it discriminates between people with different trait levels, and where its response thresholds fall along the trait continuum. Because the ten personality aspects are correlated and each item is written to tap one aspect within a broader domain, the researchers fit confirmatory multidimensional models rather than treating each aspect in isolation. This approach allowed them to test whether the hypothesized two-aspect structure actually held within each of the five Big Five domains in the Italian data.

The results were encouraging. Across all ten aspects, the confirmatory MIRT models showed acceptable to strong factor loadings and discrimination parameters, with response thresholds that were well ordered, meaning the answer options functioned as intended along the trait scale. Bayesian fit statistics told a consistent story: standardized root mean square residual values ranged from 0.045 to 0.063, root mean square error of approximation values from 0.032 to 0.045, and comparative and Tucker-Lewis fit indices ranged from 0.950 to 0.975. In conventional terms, these numbers indicate acceptable to strong model fit, supporting the structural validity of the two-factor solutions within each domain. In plain language, the Italian items grouped themselves into the same ten aspects that theory predicted, without needing to be reshuffled or discarded.

Reliability, the consistency with which the items measure each aspect, was assessed using Bayesian methods rather than traditional point estimates alone. The resulting estimates ranged from low to excellent across the ten aspects, a spread that is not unusual for very short scales. With only four items per aspect, some aspects inevitably show weaker internal consistency than others, and the authors are transparent about this variability. The Bayesian framework is particularly well suited to this kind of evaluation because it produces full distributions of the reliability estimates rather than single numbers, giving researchers a more honest picture of the precision of the measurement in a sample of this size.

Validity was then tested against external criteria. The Italian BFAS-40 was administered alongside the Big Five Inventory short form, allowing the researchers to check whether the new scale’s domain scores converged with an established measure of the same constructs. They also examined associations with indices of well-being and with measures of depression, anxiety, and stress drawn from the DASS-21. The pattern of correlations supported both convergent and discriminant validity: aspects related to negative emotionality, such as withdrawal and volatility, correlated with distress measures in the expected directions, while aspects tied to positive engagement aligned with well-being scores. This network of expected relationships suggests the translated items are measuring the same psychological substance as their English originals, not merely producing superficially similar responses.

Perhaps the most internationally significant part of the study is its cross-cultural comparison. The researchers compared item functioning between the Italian sample and a Canadian sample of 347 participants, using differential item functioning analysis, a technique that detects whether an item behaves differently for people from different groups after accounting for their trait levels. Of the 40 items, 39 showed no evidence of differential functioning between Italian and Canadian respondents. Only a single Agreeableness item was flagged. This near-perfect record is remarkable for a translated personality measure and suggests that the Italian adaptation achieved what psychometricians call measurement equivalence, the property that allows scores to be compared meaningfully across cultures rather than within each country alone.

The one flagged item is worth noting rather than dismissing. Agreeableness, which splits into compassion and politeness, is the aspect most closely tied to social values and interpersonal norms, domains where cultural expectations differ most between countries. An item that functions differently across cultures does not necessarily indicate a translation error; it may reflect genuine cultural variation in how agreeable behavior is expressed or interpreted. For researchers planning cross-cultural studies, the practical implication is that 39 of the 40 Italian items can be used in direct comparison with Canadian data, while the flagged Agreeableness item should be interpreted with caution in such analyses.

The study arrives at a moment when demand for brief, validated personality measures is accelerating. Short scales are increasingly used in electronic health records, large online panels, and studies that follow thousands of people over time, where every additional minute of questionnaire length translates into dropout. Recent work has extended the BFAS-40 to German, French, and Italian samples, and the present study adds a level of statistical scrutiny, multidimensional item response modeling with Bayesian estimation and formal cross-cultural DIF testing, that goes beyond typical translation checks. For Italian-speaking researchers and clinicians, the BFAS-40 now offers a theoretically grounded, efficient tool that captures the ten aspects of the Big Five in a fraction of the time of the original instruments. For the broader field, it demonstrates that careful psychometric engineering can make even a nuanced hierarchical model of personality travel across languages without losing its shape, a small but meaningful step toward personality science that speaks with one measurement language worldwide.

The research team recruited 662 Brazilian adults aged 18 to 71, with a mean age of about 35 years. Roughly 80 percent of participants were women, and most resided in the state of São Paulo. Data were collected online in April 2022 through Google Forms, with participants providing informed consent and confirming they were at least 18 years old. The sample also carried rich mental health context: nearly 43 percent reported having undergone psychological treatment at some point, about 40 percent were currently in treatment, and roughly 62 percent reported no psychiatric diagnosis. This community-based composition gives the study a window into how dark traits manifest in everyday life rather than exclusively in clinical or forensic settings.

Methodologically, the study stands out for its sophistication. Rather than relying on simple correlations, the researchers employed exploratory structural equation modeling, or ESEM, a flexible statistical framework that allows latent factors to load on multiple indicators without the rigid constraints of confirmatory approaches. Analyses were conducted in R using the lavaan package, with a robust weighted least squares estimator and gender included as a covariate through a MIMIC modeling design, ensuring that reported associations held independent of gender effects. Model fit was evaluated against established benchmarks, and the final models achieved satisfactory indices, with comparative fit values around 0.95 and root mean square error values well below conventional thresholds.

The instruments themselves spanned the personality landscape. Dark traits were measured with the Dark Triad Dirty Dozen, a 12-item self-report scale with four items per trait, alongside the Single Item Narcissism Scale. To capture narcissism in greater depth, the team used the Pathological Narcissism Inventory, a 52-item measure distinguishing grandiose facets such as exploitativeness and entitlement rage from vulnerable facets such as hiding the self and contingent self-esteem. Socioemotional skills were assessed with the SENNA inventory, a 54-item instrument organized around five domains that parallel the Big Five: engaging with others (extraversion), amity (agreeableness), self-management (conscientiousness), emotional resilience (neuroticism), and openness to the new (openness). All scales showed acceptable to good internal consistency in the sample.

The headline finding is strikingly consistent: every Dark Triad trait was negatively associated with amity, the socioemotional skill domain corresponding to agreeableness. Machiavellianism showed a strong negative association with amity (−0.58) alongside a positive link to engaging with others (0.30). Psychopathy displayed the strongest antagonism link of all (−0.73), paired with a moderate positive association with openness to the new (0.30). Narcissism, measured in multiple ways, combined positive associations with social engagement (0.41 for the Dirty Dozen version) with negative ties to amity (−0.50) and emotional resilience (−0.31). In other words, the common core of darkness is antagonism—a pattern of manipulativeness, callousness, deceitfulness, and hostility that researchers increasingly regard as the shared backbone of all three traits.

Beneath that shared core, the study revealed trait-specific signatures. The positive association between psychopathy and openness caught the authors’ attention: traits such as novelty seeking and imagination may accompany the impulsivity and moral norm violation characteristic of psychopathy, though the authors caution that the Dirty Dozen’s limited coverage of the construct means this link likely reflects impulsivity and emotional dysregulation rather than the cold, calculating features of primary psychopathy. Meanwhile, the positive ties between Machiavellianism, narcissism, and engaging with others suggest that socially dominant, assertive, even charming behavior can coexist with exploitative motives—a kind of pathological extraversion built for manipulation rather than genuine connection.

One of the most culturally intriguing threads involves the Brazilian jeitinho, an emic construct describing the creative, persuasive, sometimes rule-bending knack for achieving personal goals. Because jeitinho shares features with Dark Triad traits—strategic social manipulation and self-promotion—it may help explain why Machiavellianism plays a prominent role in Brazilian personality networks compared with other countries. The authors suggest that in sociocultural contexts like Brazil, individuals high in Machiavellianism may deploy interpersonal strategies that, though instrumentally motivated, are perceived as positive social engagement, potentially inflating the observed correlation between Machiavellianism and the engaging-with-others domain. Cross-cultural studies have indeed flagged Brazil as showing some of the largest differences in Dark Triad item responses relative to countries such as Greece and Japan.

The study’s treatment of narcissism may prove its most clinically valuable contribution. By modeling the facets of the Pathological Narcissism Inventory separately, the researchers showed that grandiose and vulnerable narcissism carry distinct socioemotional profiles. Grandiose facets—exploitativeness, grandiose fantasies, entitlement rage—tended to pair with high social engagement and low amity, with exploitativeness showing a positive association with engaging with others (0.35). Vulnerable facets told a different story: contingent self-esteem was moderately associated with low emotional resilience (−0.37), and hiding the self was negatively associated with social engagement (−0.34) while positively linked to openness (0.28). Both dimensions shared low amity, reinforcing the idea that antagonism is central to pathological narcissism, while emotional resilience and amity help separate the grandiose from the vulnerable expressions.

The authors are candid about limitations. The Dirty Dozen primarily captures callous affect and impulsive psychopathy, omitting dimensions such as antisocial behavior and interpersonal manipulation. The sample’s predominantly female composition, roughly 80 percent, limits generalizability to men despite statistical controls. The single-item narcissism measure, while convenient, may inflate associations with assertiveness and fail to capture vulnerability. And because the design was cross-sectional, the direction of causality between dark traits and socioemotional skills remains an open question, calling for longitudinal and experimental follow-ups in more gender-balanced samples.

Even so, the implications are compelling. If dark personality traits can be understood as chronic deficits or imbalances in trainable socioemotional competencies, then interventions that strengthen amity—or curb the manipulative, exploitative forms of social engagement—might genuinely reduce antagonistic tendencies and their damaging interpersonal fallout. The study reframes the Dark Triad not as an immutable curse of character but as a specific, mappable pattern of socioemotional strengths and deficits, one that future research may learn to reshape.
