Power rewires grammar: feeling powerful weakens syntactic priming in dialogue

When two people talk, their grammar quietly begins to converge. If one person describes a scene with a passive construction, the other becomes measurably more likely to use a passive construction moments later. This phenomenon, known as syntactic priming, has been documented for decades in language production research and is often treated as a near-automatic echo of the structures we hear. But a new study published in Current Psychology suggests that this echo is not equally loud in everyone. According to the research, people who feel powerful show a weaker syntactic priming effect than people who feel powerless, providing the first experimental evidence that social power reshapes the way we perceive and produce sentence structure.

The study, conducted by Heng Li of Sichuan International Studies University in Chongqing, China, tested a deceptively simple theoretical proposal. High-power individuals, the argument goes, experience a heightened sense of autonomy, authority, and confidence. That psychological state reduces the pressure to align with others, because powerful people are less dependent on their interlocutors and less motivated to accommodate them. Low-power individuals, by contrast, live in a social world where dependence, vigilance, and the need for acceptance are more salient, which should make them more inclined to mirror the linguistic behavior of the people around them. If that reasoning is correct, then the strength of syntactic priming should vary systematically with power, and the difference should appear even when power is only temporarily induced in the laboratory.

Syntactic priming itself is one of the most robust findings in psycholinguistics. In the classic paradigm established by Kathryn Bock in the 1980s, participants who read or hear a sentence with a particular structure, such as a double-object dative, become more likely to describe an unrelated picture using that same structure. The effect persists across modalities, ages, and languages, and meta-analyses have confirmed its strength in language production. Researchers have proposed two broad mechanistic accounts. One treats priming as transient activation of syntactic representations in a spreading-activation production system. The other treats it as a form of implicit learning, in which the language system updates its expectations about which structures are likely to recur. Either way, the effect operates largely beneath conscious awareness, which makes it a sensitive probe for detecting how psycho-social states modulate linguistic processing.

What makes the new work notable is that most prior research on the social modulation of priming has focused on factors such as social opinion, ostracism, speaker accent, or communicative context. Social power, a foundational construct in social psychology defined as the capacity to influence others while being relatively resistant to influence oneself, had been largely unexplored in this domain. Yet power is known to alter a wide range of perceptual and cognitive processes. Previous studies have shown that high-power individuals process information more abstractly, take others’ perspectives less often, show reduced mirroring responses in the brain, and recognize emotional prosody in voices with lower accuracy than low-power individuals. Power also elevates self-concept consistency and authenticity, and it shapes expectations of social acceptance. If power dampens the tendency to imitate in these domains, the language system should be no exception.

To test this prediction, Li ran two studies using different priming methodologies and different participant populations, a design choice intended to guard against the possibility that any observed pattern is an artifact of a single task or a single group. Study 1 recruited Chinese student participants and used a dialogue-based writing task. Participants were first primed with either high power or low power, a standard social-priming manipulation in which people recall and describe an experience in which they had power over others or in which others had power over them. They then engaged in dialogue with interlocutors whose sentence structures were controlled by the experimenters. The key measure was whether participants subsequently adopted the syntactic structures their interlocutors had used. The results were clear: participants primed with high power were less likely to adopt the syntactic structures used by their interlocutors than participants primed with low power.

Study 2 corroborated the finding with a different task and a different population. This time the participants were community adults rather than students, and the priming methodology was a sentence scrambling task rather than a dialogue writing task. In sentence scrambling paradigms, participants rearrange words or phrases to form sentences, and the structures they produce reveal which syntactic representations have been activated by recent exposure. Once again, participants with high power exhibited a less pronounced syntactic priming effect than participants with low power. The convergence across two tasks, two participant groups, and two experimental formats strengthens the conclusion that the power effect is not tied to any particular methodological quirk but reflects a genuine modulation of the alignment process itself.

The theoretical significance of these results extends beyond the laboratory. Communication accommodation theory, developed by Howard Giles and colleagues, holds that speakers adjust their linguistic behavior toward or away from their interlocutors depending on their social goals, with convergence signaling affiliation and approval. The new findings suggest that power is a hidden moderator of this accommodation process. Powerful speakers, feeling less dependent on their partners, accommodate less, while powerless speakers, whose social outcomes hinge more on acceptance, accommodate more. This asymmetry could help explain a familiar feature of everyday conversation: in interactions between bosses and subordinates, teachers and students, or any pair with a power differential, the grammatical convergence may flow disproportionately from the less powerful side. Over time, such one-sided alignment could shape the linguistic norms of entire communities, since the structures favored by powerful speakers may spread more widely than those favored by powerless ones.

The findings also connect to a broader research program on imitation and social learning. Imitation, whether of gestures, facial expressions, or sentence structures, is a cornerstone of human sociality and a mechanism of cumulative cultural evolution. Previous work by the same author showed that social ostracism, the experience of being excluded, selectively increases language imitation, presumably because excluded individuals are motivated to regain acceptance through affiliation. The power results now complete the picture from the opposite direction: whereas exclusion amplifies the echo of others’ grammar, power mutes it. Together, these studies suggest that syntactic priming is not a fixed property of the language system but a flexible alignment behavior whose strength tracks the speaker’s social circumstances. The perception and production of language, the study concludes, vary significantly between individuals experiencing high and low power, highlighting the profound influence of social dynamics on linguistic processes.

Several caveats and open questions remain. The studies relied on temporarily induced power rather than stable individual differences in power motivation, so it is not yet known whether chronically powerful people, such as long-term leaders, show persistently weaker priming. The participants were Chinese speakers, and although syntactic priming is well documented across languages, including contrastive work on passive constructions in English and Chinese, cross-cultural replication would strengthen the general claim. The data supporting the findings are available from the corresponding author upon reasonable request, and the study received no external funding. Future research could examine whether the power effect interacts with expectation-based accounts of priming, in which alignment strength depends on the prediction error of the prime, or whether it extends to alignment at other linguistic levels, such as word choice and speech rate. It could also test whether the effect reverses in cooperative contexts, since prior work has shown that power and context jointly moderate verbal mimicry.

For now, the message is striking. The grammar we produce in conversation is quietly tuned by how powerful we feel. A person who feels in charge is less likely to borrow the sentence structures of the person they are talking to, while a person who feels subordinate is more likely to echo them. Language, in other words, is not just a vehicle for transmitting content; it is a social instrument whose alignment settings are calibrated by power. Every dialogue, from a hallway exchange to a boardroom negotiation, carries these linguistic echoes of hierarchy, and the new research shows that the echoes are loudest on the less powerful side.
