Description
Past research on knowledge has differentiated between dimensions of knowledge, for example amount or coherence. This dissertation introduces a novel dimension of knowledge, the Motivational Utility of Knowledge (MUK), that is based on hierarchies of human needs (e.g., physical safety, status/esteem, actualization, reproduction). The effects of MUK are tested in a set of four studies on the topic of houselessness. All four studies used the same dataset. Adults in the United States (N = 190) were recruited from an online survey platform and paid for participation. They were first asked about their conceptions of houselessness. Next, they read a set of four texts arguing different views of houselessness, and administered a comprehension test, an emotion while reading test, and asked if the text conflicted with their beliefs. They were then reassessed on their conceptions and administered the MUK scale. Finally, they were given a demographics questionnaire, including questions about their personal experience with houselessness, and were administered a general prior knowledge test and a vocabulary knowledge test. Study 1 examined MUK as a construct and assessed the factor structure of the scale. The analyses showed that the subscales of MUK loaded onto a single factor – overall value of houselessness knowledge. Study 2 situated MUK within the domain of conceptual change. The results demonstrated that participants’ conceptions of houselessness were related to MUK, and that their propensity to engage in conceptual change depended on MUK. Study 3 situated MUK within the domain of text comprehension research and demonstrated that the text-belief consistency effect is enhanced when participants have high MUK. Finally, Study 4 examined MUK as a mediator between conceptions and comprehension and examined the role of MUK in predicting negative emotions. Overall, the findings suggest that MUK plays a role in conceptual change and text comprehension such that participants with high MUK are less likely to revise their knowledge and have worse comprehension when the text conflicts with their beliefs. In addition, MUK may predict emotions while reading about controversial topics, as participants with high MUK were more likely to report negative emotions while reading.

Description
Stereotype humor is a highly prevalent but particularly divisive phenomenon, with the potential for both negative and positive social implications. While highly subjective, interpretations of stereotype humor's subtext (support/challenge of stereotype) have major implications for reactions to this type of humor. This experimental study (N = 104) represents a novel investigation of the effect of two facets of stereotype humor, explicitness of stereotyping and stereotype distortion, on judgments of stereotype endorsement (support) versus subversion (challenge) in memes about four different groups (Asian, Hispanic, Irish, White) and associated group stereotypes. In this completely within-subjects design, participants viewed several memes about the target groups which varied systematically by the two factors of interest and provided judgments of stereotype endorsement versus subversion, ratings of funniness, and ratings of offensiveness. Multilevel models were used to determine the effect of explicitness, distortion, and their interaction, as well as target group, on judgements of stereotype humor while accounting for nesting of responses within participants. Results showed that stereotype distortion (e.g., exaggeration) and explicit stereotyping (e.g., overtly linking group to stereotype) both significantly predicted greater ratings of subversion. Unexpectedly, stereotype distortion also predicted greater levels of offense. Interestingly, marginalized group membership (i.e., Asian, Hispanic) significantly predicted lower ratings of subversion, lower funny ratings, and higher offense ratings. Findings highlight the significant role of explicitness and distortion when considering how individuals interpret the subtext of stereotype humor. Furthermore, findings underscore the major influence of group status on judgments and social implications of this type of humor. Overall, this study contributes to a better understanding of the mechanisms by which individuals interpret stereotype humor, providing valuable insights for promoting better intergroup relations and communication.

Description
The current work investigated the emergence of leader-follower roles during social motor coordination. Previous research has presumed a leader during coordination assumes a spatiotemporally advanced position (e.g., relative phase lead). While intuitive, this definition discounts what role-taking implies. Leading and following is defined as one person (or limb) having a larger influence on the motor state changes of another; the coupling is asymmetric. Three experiments demonstrated asymmetric coupling effects emerge when task or biomechanical asymmetries are imputed between actors. Participants coordinated in-phase (Ф =0o) swinging of handheld pendulums, which differed in their uncoupled eigenfrequencies (frequency detuning). Coupling effects were recovered through phase-amplitude modeling. Experiment 1 examined leader-follower coupling during a bidirectional task. Experiment 2 employed an additional coupling asymmetry by assigning an explicit leader and follower. Both experiment 1 and 2 demonstrated asymmetric coupling effects with increased detuning. In experiment 2, though, the explicit follower exhibited a phase lead in nearly all conditions. These results confirm that coupling direction was not determined strictly by relative phasing. A third experiment examined the question raised by the previous two, which is how could someone follow from ahead (i.e., phase lead in experiment 2). This was tested using a combination of frequency detuning and amplitude asymmetry requirements (e.g., 1:1 or 1:2 & 2:1). Results demonstrated larger amplitude movements drove the coupling towards the person with the smaller amplitude; small amplitude movements exhibited a phase lead, despite being a follower in coupling terms. These results suggest leader-follower coupling is a general property of social motor coordination. Predicting when such coupling effects occur is emphasized by the stability reducing effects of coordinating asymmetric components. Generally, the implication is role-taking is an emergent strategy of dividing up coordination stabilizing efforts unequally between actors (or limbs).
