Chronic and temporary aggression causes hostile false memories for ambiguous information

Chronic and temporarily aggressive people show a phenomenon known as the hostile attribution bias (HAB), in which access to hostile schemas leads them to interpret ambiguously hostile information in a hostile way. Can these people also be induced to remember unambiguously hostile, yet completely false information? To address this question, we investigated the effect of both chronic and temporary aggression on recall for a list containing words that could be interpreted as exemplars of either an aggressive (violence‐related) or non‐aggressive (kitchen‐related) category. Subjects were exposed to five consecutive lists of associated words including the ambiguous list, but half read a list of insult words immediately before presentation of the ambiguous list, while the other half read only emotionally neutral lists. When recalling the ambiguous list, aggressive subjects and subjects who were primed with insult words were more likely to report having seen unpresented aggressive words compared with their low aggressive and not primed counterparts. We discuss our findings in line with Anderson and Bushman's (2002) General Aggression Model (GAM). Copyright © 2007 John Wiley & Sons, Ltd.     

How Many Perspectives Provide a Compass? Differentiating 360‐Degree and Multi‐Source Feedback

Researchers have been inconsistent regarding (a) the relationship between 360° feedback and multi‐source feedback and (b) the definition of 360° feedback. In the present paper, we review these topics and offer two solutions that could facilitate effective communication about these terms.     

Harm inflation: Making sense of concept creep

ABSTRACT

“Concept creep” is the gradual semantic expansion of harm-related concepts such as bullying, mental disorder, prejudice, and trauma. This review presents a synopsis of relevant theoretical advances and empirical research findings on the phenomenon. It addresses three fundamental questions. First, it clarifies the characterisation of concept creep by refining its theoretical and historical dimensions and presenting studies investigating the change in harm-related concepts using computational linguistics. Second, it examines factors that have caused concept creep, including cultural shifts in sensitivity to harm, societal changes in the prevalence of harm, and intentional meaning changes engineered for political ends. Third, the paper develops an account of the consequences of concept creep, including social conflict, political polarisation, speech restrictions, victim identities, and progressive social change. This extended analysis of concept creep helps to understand its mixed implications and sets a multi-pronged agenda for future research on the topic.     

Participatory action research: towards (non-ideal) epistemic justice in a university in South Africa

ABSTRACT

The paper explores the possibilities for promoting epistemic justice in a South African university setting through a participatory action-based photovoice research project in which university researchers worked alongside undergraduate students with no prior experience of doing research. The student voices are employed to understand how learning as capability development and agency expansion can advance epistemic justice in a university setting of hierarchical relationships that make participatory action research challenging. The paper considers how, in this project, spaces of epistemic democracy intersected with the expansion of multidimensional functionings, resulting in more epistemic justice for the student-researchers. The paper considers the possibilities for change through a participatory project toward promoting epistemic justice at the individual level. It also explores some criticisms of the limits of such individual development in the face of structural challenges.     

Dissociable lexical and phonological influences on serial recognition and serial recall

The impact of the lexicality of memory items on memory performance was compared in two paradigms, serial recall and serial recognition. Experiments 1 to 3 tested 7- and 8-year-old children. Memory accuracy was only mildly impaired in lists containing nonwords compared with words in a serial recognition task involving judgements of whether the items in two sequences were in the same order (Experiment 1), although a substantial advantage for word over nonword items from the same stimulus pool was found in serial recall (Experiment 2). A stronger influence of lexicality on serial recall than serial recognition was further demonstrated in Experiments 3A and 3B, and in 4A and 4B using adult participants. These experiments also established comparable degrees of sensitivity to the phonological similarity of the memory sequences in the two paradigms. The phonological similarity effect in serial recall was found to arise from increased phoneme order errors, whereas the lexicality effect was due principally to the greater frequency of phoneme identity errors for nonwords. It is proposed that the lexicality effect originates in the redintegration of item information just prior to recall, and that this process is largely bypassed in serial recognition.     

Correlates of unhealthy weight-control behaviors among adolescents: implications for prevention programs.

This study aimed to identify correlates of unhealthy weight-control behaviors in adolescents to guide the development of programs aimed at the primary prevention of disordered eating. A model explaining unhealthy weight-control behaviors was tested among 4,746 adolescents using structural equation modeling. Models fit the data well and explained 76% of the variance in unhealthy weight-control behaviors among girls and 63% among boys. Weight-body concerns were a strong correlate of unhealthy weight-control behaviors in both girls and boys. Models also emphasized the importance of weight-specific social norms within the adolescent's proximal environment. Findings suggest the importance of addressing weight-body concerns within prevention programs and extending interventions beyond classroom settings to ensure changes in weight-related norms among peer groups and family members.
