Changes in Politics and Religiosity Among Students at a Protestant University

College is a setting and time of profound change in the lives of emerging adults. This change can include shifts in identity related to politics and religion. Given widespread attention to the alignment of religious people with conservative politics and less religious people with liberal politics (i.e., the “God Gap”), we ask: do college students who become politically liberal lose their religion in the process? Using longitudinal panel data, this study examines changes in political identity and religiosity among students at a Protestant university. Findings reveal changes in students’ politics align with changes in public and private religious behaviors, certainty in belief, agreement with core tenets of the Christian faith, faith maturity, and closeness to God. Whereas students who become more politically conservative increase their religiosity, the inverse is true for those whose politics become more liberal in college.     

A preliminary exploration of predictors of outcome and cognitive mechanisms of change in cognitive behaviour therapy for psychosis in people not taking antipsychotic medication

BackgroundCognitive behaviour therapy (CBT) has been shown to be effective in an open trial for people with psychotic disorders who have not been taking antipsychotic medication. There is little known about predictors of outcome in CBT for psychosis and even less about hypothesised mechanisms of change.Method20 participants with schizophrenia spectrum disorders received CBT in an exploratory trial. Our primary outcome was psychiatric symptoms measured using the PANSS. Secondary outcomes were dimensions of hallucinations and delusions, self-rated recovery and social functioning, and hypothesised mechanisms of change included appraisals of psychotic experiences, dysfunctional attitudes and cognitive insight. We also measured patient characteristics that may be associated with outcome.ResultsT-tests revealed that several of the hypothesised mechanisms did significantly change over the treatment and follow-up periods. Correlational analyses showed that reductions in negative appraisals of psychotic experiences were related to improvements on outcome measures and that shorter duration of psychosis and younger age were associated with greater changes in symptoms.ConclusionsCBT based on a specific cognitive model appears to change the hypothesised cognitive mechanisms, and these changes are associated with good outcomes. CBT may be more effective for those who are younger with shorter histories of psychosis.     

A claw is like my hand: comparison supports goal analysis in infants

Understanding the intentional relations in others' actions is critical to human social life. Origins of this knowledge exist in the first year and are a function of both acting as an intentional agent and observing movement cues in actions. We explore a new mechanism we believe plays an important role in infants' understanding of new actions: comparison. We examine how the opportunity to compare a familiar action with a novel, tool use action helps 7- and 10-month-old infants extract and imitate the goal of a tool use action. Infants given the chance to compare their own reach for a toy with an experimenter's reach using a claw later imitated the goal of an experimenter's tool use action. Infants who engaged with the claw, were familiarized with the claw's causal properties, or learned the associations between claw and toys (but did not align their reaches with the claw's) did not imitate. Further, active participation in the familiar action to be compared was more beneficial than observing a familiar and novel action aligned for 10-month-olds. Infants' ability to extract the goal-relation of a novel action through comparison with a familiar action could have a broad impact on the development of action knowledge and social learning more generally.     

Emotion, directed forgetting, and source memory

We investigated the role of emotion on item and source memory using the item method of directed forgetting (DF) paradigm. We predicted that emotion would produce source memory impairment because emotion would make it more difficult to distinguish between to-be-remembered (R items) and to-be-forgotten items (F items) by making memory strength of R and F items similar to each other. Participants were presented with negatively arousing, positively arousing, and neutral pictures. After each picture, they received an instruction to remember or forget the picture. At retrieval, participants were asked to recall both R and F items and indicate whether each item was an R or F item. Recall was higher for the negatively arousing than for the positively arousing or neutral pictures. Further, DF occurred for the positively arousing and neutral pictures, whereas DF was not significant for the negatively arousing pictures. More importantly, the negatively arousing pictures, particularly the ones with violent content, showed a higher tendency of producing misattribution errors than the other picture types, supporting the notion that negative emotion may produce source memory impairment, even though it is still not clear whether the impairment occurs at encoding or retrieval.     

TRIAL-BASED FUNCTIONAL ANALYSIS AND FUNCTIONAL COMMUNICATION TRAINING IN AN EARLY CHILDHOOD SETTING

Problem behavior is common in early childhood special education classrooms. Functional communication training (FCT; Carr & Durand, 1985 ) may reduce problem behavior but requires identification of its function. The trial‐based functional analysis (FA) is a method that can be used to identify problem behavior function in schools. We conducted trial‐based FAs and FCT with 3 children in an early childhood special education setting. All trial‐based FAs resulted in identification of behavioral functions, and subsequent FCT led to reductions in problem behavior and increases in communication.     

Mangy mutt or furry friend? Anthropomorphism promotes animal welfare

Recent research has demonstrated that people have an affinity for non-human entities that appear to have human qualities. The current studies build on this research, examining whether anthropomorphism can be used to promote animal welfare. In Study 1 (n = 42), participants read scenarios about dogs and reported more willingness to help the ones described with anthropomorphic language relative to those described with non-anthropomorphic language. In Study 2 (n = 57), participants rated dogs on either human or canine characteristics (e.g., good listener vs. good at listing to commands). Relative to the non-anthropomorphism condition, participants in the anthropomorphism condition reported more willingness to adopt dogs from a shelter, and more support for animal rights, animal welfare, and vegetarian and vegan attitudes. Moreover, these pro-animal attitudes fully mediated the effect of the anthropomorphism manipulation on willingness to adopt the dogs.     

How we know what we intend

How do we know what our intentions are? It is argued that work on self-knowledge has tended to neglect the attitude of intention, and that an epistemological account is needed that is attuned to the specific features of that state. Richard Moran??s ??Authorship?? view, on which we can acquire self-knowledge by making up our minds, offers a promising insight for such an account: we do not normally discover what we intend through introspection. However, his formulation of the Authorship view, developed primarily with the attitude of belief in mind, is found wanting when applied to intention. An alternative account is proposed for knowledge of one??s own intentions that gives a central role to the mental act of deciding what to do. It is argued that we can come to know what we intend by making a decision about what to do and self-ascribing the content of that decision as our intended action.     

Conflict Transformation, Stigma, and HIV-Preventive Structural Change

Over the prior decade, structural change efforts have become an important component of community-based HIV prevention initiatives. However, these efforts may not succeed when structural change initiatives encounter political resistance or invoke conflicting values, which may be likely when changes are intended to benefit a stigmatized population. The current study sought to examine the impact of target population stigma on the ability of 13 community coalitions to achieve structural change objectives. Results indicated that coalitions working on behalf of highly stigmatized populations had to abandon objectives more often than did coalitions working for less stigmatized populations because of external opposition to coalition objectives and resultant internal conflict over goals. Those coalitions that were most successful in meeting external challenges used opposition and conflict as transformative occasions by targeting conflicts directly and attempting to neutralize oppositional groups or turn them into strategic allies; less successful coalitions working on behalf of stigmatized groups struggled to determine an appropriate response to opposition. The role of conflict transformation as a success strategy for working on behalf of stigmatized groups is discussed.     

Looking like a criminal: Stereotypical black facial features promote face source memory error

The present studies tested whether African American face type (stereotypical or nonstereotypical) facilitated stereotype-consistent categorization, and whether that categorization influenced memory accuracy and errors. Previous studies have shown that stereotypically Black features are associated with crime and violence (e.g., Blair, Judd, & Chapleau Psychological Science 15:674?C679, 2004; Blair, Judd, & Fallman Journal of Personality and Social Psychology 87:763?C778, 2004; Blair, Judd, Sadler, & Jenkins Journal of Personality and Social Psychology 83:5?C252002); here, we extended this finding to investigate whether there is a bias toward remembering and recategorizing stereotypical faces as criminals. Using category labels, consistent (or inconsistent) with race-based expectations, we tested whether face recognition and recategorization were driven by the similarity between a target??s facial features and a stereotyped category (i.e., stereotypical Black faces associated with crime/violence). The results revealed that stereotypical faces were associated more often with a stereotype-consistent label (Study 1), were remembered and correctly recategorized as criminals (Studies 2?C4), and were miscategorized as criminals when memory failed. These effects occurred regardless of race or gender. Together, these findings suggest that face types have strong category associations that can promote stereotype-motivated recognition errors. Implications for eyewitness accuracy are discussed.
