Leadership is inextricably embedded in human groups. One central obligation of leaders is to embody the identity of their group by acting in line with group norms. Yet little is known about how leadership and conformity are initially associated in people's minds, how this association develops in childhood, and how cultural values shape this association. The present research tested 4- to 11-year-olds in the United States and China to address these questions by comparing children's evaluations of a leader's versus an ordinary group member's nonconformity. In Experiments 1 and 3 (N = 114 and 116, respectively), children saw two novel groups engage in distinct behaviors (e.g., listening to different kinds of music). A leader or a nonleader acted against their respective group norms. Next, children provided evaluations of the nonconformity. In both populations, whereas younger children (4- to 7-year-olds) evaluated the leader's nonconformity more positively relative to the nonleader's, older children (10- to 11-year-olds) evaluated the leader's nonconformity more negatively. Notably, children in China developed more negative attitudes toward a leader's nonconformity than children in the United States. Experiment 2 (N = 66) ruled out the possibility that younger children's favorable evaluations of the leader's nonconformity stemmed from their general positivity toward leaders. Taken together, children in the two countries gradually conceptualize leaders as central group members and expect them to follow group norms. These findings contribute to theories on early leadership cognition and highlight the importance of taking a cross-cultural approach to understand its development.

We experience the world in terms of both (continuous) time and (discrete) events, but time seems especially primitive-since we cannot perceive events without an underlying temporal medium. It is all the more intriguing, then, to discover that event segmentation can itself influence how we perceive the passage of time. We demonstrated this using a novel "rhythmic reproduction" task, in which people listened to irregular sequences of musical tones, and then immediately reproduced those rhythmic patterns from memory. Each sequence contained a single salient (and entirely task-irrelevant) perceptual event boundary, but the temporal placement of that boundary varied across multiple trials in which people reproduced the same underlying rhythmic pattern. Reproductions were systematically influenced by event boundaries in two complementary ways: tones immediately following event boundaries were delayed (being effectively played "too late" in the reproductions), while tones immediately preceding event boundaries were sped up (being effectively played "too early"). This demonstrates how event segmentation influences time perception in subtle and nonuniform ways that go beyond global temporal distortions-with dilation across events, but contraction within events. Events structure temporal experience, facilitating a give-and-take between the subjective expansion and contraction of time. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Showing or telling others that we are committed to cooperate with them can boost social cooperation. But what makes us willing to signal our cooperativeness, when it is costly to do so? In two experiments, we tested the hypothesis that agents engage in social commitments if their subjective confidence in predicting the interaction partner's behavior is low. In Experiment 1 (preregistered), 48 participants played a prisoner's dilemma game where they could signal their intentions to their co-player by enduring a monetary cost. As hypothesized, low confidence in one's prediction of the co-player's intentions was associated with a higher willingness to engage in costly commitment. In Experiment 2 (31 participants), we replicate these findings and moreover provide causal evidence that experimentally lowering the predictability of others' actions (and thereby confidence in these predictions) motivates commitment decisions. Finally, across both experiments, we show that participants possess and demonstrate metacognitive access to the accuracy of their mentalizing processes. Taken together, our findings shed light on the importance of confidence representations and metacognitive processes in social interactions.

Object and word recognition are both cognitive processes that transform visual input into meaning. When reading words, the frequency of their occurrence ("word frequency," WF) strongly modulates access to their meaning, as seen in recognition performance. Does the frequency of objects in our world also affect access to their meaning? With object labels available in real-world image datasets, one can now estimate the frequency of occurrence of objects in scenes ("object frequency," OF). We explored frequency effects in word and object recognition behavior by employing a natural versus man-made categorization task (Experiment 1) and a matching-mismatching priming task (Experiments 2-3). In Experiment 1, we found a WF effect for both words and objects but no OF effect. In Experiment 2, we replicated the WF effect for both stimulus types during cross-modal priming but not uni-modal priming. Moreover, in cross-modal priming, we found an OF effect for both objects and words, but with faster responses when objects occur less frequently in image datasets. We replicated this counterintuitive OF effect in Experiment 3 and suggest that better recognition of rare objects might interact with the structure of object categories: while access to the meaning of objects and words is faster when their meaning often occurs in our language, the homogeneity of object categories seems to also impact recognition, mainly when semantic processing happens in the context of previously presented information. These findings have major implications for studies attempting to include frequency measures in investigations of access to meaning from visual inputs.

Visual working memory maintains both continuous-perceptual information and discrete-categorical information about memory items. Both types of information are represented in working memory, but the representation structure remains unknown. Continuous and categorical information about a single stimulus could be represented separately, in two different representations. Alternatively, continuous and categorical information could be represented jointly as a single representation. To investigate this, we fitted two different computational models to delayed estimation data assuming either separate or joint representations of continuous and categorical information in working memory, for three different, commonly used features (orientation, color, and shape). Across a set of nine experiments, model fits clearly show that feature identity drives the representation structure, with a joint-representation structure for orientation, but a separate-representations structure for color and shape. This pattern was remarkably invariant across a variety of task contexts. Existing models miss this distinction, leading to mischaracterization of memory precision.

People often hear stories about individuals who persist to overcome their constraints. While these stories can be motivating, emphasizing others' persistence may promote unwarranted judgments about constrained individuals who do not persist. Using a developmental social inference task (Study 1a: n = 124 U.S. children, 5-12 years of age; Study 1b: n = 135 and Study 2: n = 120 U.S. adults), the present research tested whether persistence stories lead people to infer that a constrained individual who does not persist, and instead accepts the lower-quality option that is available to them, prefers it over a higher-quality option that is out of reach. Study 1 found evidence for this effect in children (1a) and adults (1b). Even persistence stories about failed outcomes, which emphasize how difficult it would have been to get the higher-quality option, had this effect. Study 2 found that the effect generalized to adults' judgments about an individual facing a different type of constraint from those mentioned in the initial stories. Taken together, emphasizing others' persistence may encourage unwarranted judgments about individuals who are still constrained to lower-quality options.

There is limited research investigating the mechanisms underlying the lower rate of posttraumatic stress disorder (PTSD) in older compared to younger adults. This study examined age differences in peritraumatic and posttraumatic reactions, and the use of two emotion regulation strategies (rumination and positive reappraisal) using a trauma film induction paradigm. Participants (45 older adults and 45 younger adults) watched a trauma film. Eye gaze, Galvanic Skin Response, peritraumatic distress, and emotion regulation were assessed during the film. Participants completed an intrusive memory diary over the next 7 days and follow-up measures of posttraumatic symptoms and emotion regulation. Findings showed no age differences in peritraumatic distress or use of rumination or positive reappraisal during film viewing. Older adults reported lower posttraumatic stress and distress from intrusive memories than younger adults at the 1-week follow-up, despite experiencing a comparable number of intrusions. Rumination was a unique predictor of intrusive and hyperarousal symptoms, after accounting for age. There were no age differences in the use of positive appraisal, and positive reappraisal was not associated with posttraumatic stress. Lower rates of late-life PTSD may relate to decreased use of maladaptive emotion regulation (i.e., rumination), rather than increased use of adaptive emotion regulation strategies (i.e., positive reappraisal).

We investigated similarities in language and motor action plans by comparing errors in parallel speech and manual tasks. For the language domain, we adopted the "tongue twister" paradigm, while for the action domain, we developed an analogous key-pressing task, "finger fumblers." Our results show that both language and action plans benefit from reusing segments of prior plans: when onsets were repeated between adjacent units in a sequence, the error rates decreased. Our results also suggest that this facilitation is most effective when the planning scope is limited, that is, when participants plan ahead only to the next immediate units in the sequence. Alternatively, when the planning scope covers a wider range of the sequence, we observe more interference from the global structure of the sequence that requires changing the order of repeated units. We point to several factors that might affect this balance between facilitation and interference in plan reuse, for both language and action planning. Our findings support similar domain-general planning principles guiding both language production and motor action. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Prospective outcomes bias behavior in a "Pavlovian" manner: Reward prospect invigorates action, while punishment prospect suppresses it. Theories have posited Pavlovian biases as global action "priors" in unfamiliar or uncontrollable environments. However, this account fails to explain the strength of these biases-causing frequent action slips-even in well-known environments. We propose that Pavlovian control is additionally useful if flexibly recruited by instrumental control. Specifically, instrumental action plans might shape selective attention to reward/punishment information and thus the input to Pavlovian control. In two eye-tracking samples (N = 35/64), we observed that Go/NoGo action plans influenced when and for how long participants attended to reward/punishment information, which in turn biased their responses in a Pavlovian manner. Participants with stronger attentional effects showed higher performance. Thus, humans appear to align Pavlovian control with their instrumental action plans, extending its role beyond action defaults to a powerful tool ensuring robust action execution.
