2D or not 2D? An fMRI study of how dogs visually process objects

Animal Cognition - Given humans’ habitual use of screens, they rarely consider potential differences when viewing two-dimensional (2D) stimuli and real-world versions of dimensional stimuli....     

The Association Between Age and Ethics-Related Issues in Using Social Media for HIV Prevention in Peru

Little research has focused on the ethical issues around using social media for HIV prevention in low- and middle-income countries, such as Peru. This study surveyed participants from the HOPE social media HIV intervention in Peru to assess their experiences and perceptions of ethical issues in the study and the impact of age on their experiences and perceptions. This study found that, compared to younger participants, older participants were more likely to express higher levels of understanding of the consent form and trust that other participants were real. Older participants also reported being less likely to benefit from learning about their HIV status. Findings suggest that age plays a role in participants’ experiences in a social-media-based HIV intervention.     

Interdisciplinary Treatment of Maladaptive Behaviors Associated with Postural Orthostatic Tachycardia Syndrome (POTS): A Case Report

The prevalence of postural orthostatic tachycardia syndrome (POTS) in adolescents and young adults has been increasing during the past decade. Despite this increase, documentation regarding treatment of these patients is just beginning to emerge. In addition, despite a call for a multidisciplinary or interdisciplinary approach, no studies have examined the efficacy of such an approach to treatment. This paper describes a case study of a 19-year-old male with debilitating POTS seen at a tertiary clinic for evaluation and subsequent intensive interdisciplinary treatment. The treatment approach is described and outcomes are presented.     

The Effects of Partner Learning During Spelling for Students with Severe Disabilities and Their Peers

A multiple baseline across subjects design was used to examine the effects of partner learning on the spelling performance, academic responding, and competing behavior of three students with severe disabilities and three of their classmates without disabilities. The students were enrolled in different general elementary classes. All students in these classes were assigned to partner learning triads by the general education teacher. One triad in each class included the student with severe disabilities and two classmates without disabilities. All students in the class received two, 20 min partner learning sessions each week. During partner learning, each member of the triad was asked to spell words, present words to be spelled, provide feedback to the speller, and check the spelling accuracy. These roles were rotated among the members of the triad after each trial. These roles were adapted as necessary to accommodate the academic and communication skills of the students with severe disabilities. The effects of partner learning on spelling accuracy were assessed through weekly spelling tests. The effects of partner learning on academic responding and competing behavior were assessed using the MS-CISSAR (Carta, Greenwood, Schulte, Arreaga-Mayer, Terry, 1988). Results of weekly spelling indicated that partner learning led to improved spelling accuracy for students with severe disabilities and did not negatively affect the spelling accuracy of their peers. Partner learning also led to improved rates of academic responding and reduced rates of competing behavior for 5 of 6 students. The results are discussed in terms of their implications for practice and future research.     

Motivated cultural cognition: the impact of implicit cultural theories on dispositional attribution varies as a function of need for closure

The authors propose that need for closure (NFC) leads attributors to respond to an ambiguous social event by increasing reliance on implicit theories received from acculturation. Hence, the influence of NFC should be shaped by chronically accessible knowledge structures in a culture, and, likewise, the influence of culture should be moderated by epistemic motives such as NFC. The specific hypotheses drew on past findings that North American and Chinese attributors possess differing implicit social theories, North Americans conceiving of individuals as autonomous agents and Chinese conceiving of groups as autonomous. The present studies found the predicted pattern that among North American participants, NFC increased attributions to personal but not group dispositions. Among Chinese participants, NFC increased attributions to group but not personal dispositions. The findings are discussed in light of an emerging dynamic account of culture and cognition.     

Specificity of auditory implicit and explicit memory: Is perceptual priming for environmental sounds exemplar specific?

Previous research (Stuart & Jones, 1995) has suggested that identification of environmental sounds may be mediated by abstract sound recognition units. This article reports the results of four repetition priming experiments that find evidence to the contrary. Participants attempted to identify environmental sounds from the initial sound stems (Experiments 1 and 2) or when the sounds were embedded in white noise (Experiments 3 and 4). Repetition of an identical exemplar sound led to more priming than did exposure to a different exemplar, provided that the perceptual difference between the two different exemplars was sufficiently large. Such an exemplar specificity effect was independent of the depth of prior encoding. A similar exemplar specificity effect was also found in explicit stem-cued recall (Experiments 1 and 2) and recognition (Experiment 3). Depth of encoding dissociated performance on tests of repetition priming and explicit memory. These results suggest that a significant amount of specific information is remembered, both implicitly and explicitly, to characterize individual exemplars of a sound category.     

Group-serving attributions across intergroup contexts: Cultural differences in the explanation of sex-typed behaviours

This research attempted to integrate Tajfel's (1978) social identity theory with self-presentational concerns by exploring attributions about perceived group differences in behaviour. As such, it dealt with group-level rather than individual-level attributions, exploring whether bias in making such verbal attributions varied as a function of the interviewer's group identity and the presence of an ingroup audience. Undergraduate men and women at The Chinese University of Hong Kong rated the appropriateness of ingroup-favouring and outgroup-favouring explanations for male-typed and female-typed behaviors in a face-to-face interview. A group-serving bias was found for female-typed behaviours, but only when the same-sex audience was absent. A conceptual replication of the experiment was run in the United States to examine the possible cultural basis for the Chinese moderation of favouritism in the audience condition. The group-serving bias was more robust for the American undergraduates, extending across male- and female-typed behaviours and also across audience conditions, It was argued that these cultural differences in attributional bias appear to reflect the strength of the movement for women's liberation and norms surrounding the avoidance of conflict in the United States and Hong Kong.     

When modesty fails: The social impact of group-effacing attributions following success or failure

This study explored how group members perceived a fellow group member who made either group-serving or group-effacing attributions following success or failure. Forty male undergraduates from the Chinese University co-operated in pairs with a confederate on a demanding group task. After learning that their group's performance had exceeded or failed to meet a standard, the subjects heard their confederate-partner make group-effacing or group-serving attributions. As predicted, subjects evaluated the group-serving partners more highly (p < 0.05). Preference for group-enhancing members was discussed as a pancultural response arising from the interdependence of group members. Given the process of social categorization, group members rise or fall together and are therefore socialized to support their group.
