Tangible pictures: viewpoint effects and linear perspective in visually impaired people

Perception of raised-line pictures in blindfolded-sighted, congenitally blind, late-blind, and low-vision subjects was studied in a series of experiments. The major aim of the study was to examine the value of perspective drawings for haptic pictures and visually impaired individuals. In experiment 1, subjects felt two wooden boards joined at 45 degrees, 90 degrees, or 135 degrees, and were instructed to pick the correct perspective drawing from among four choices. The first experiment on perspective found a significant effect of visual status, with much higher performance by the low-vision subjects. Mean performance for the congenitally blind subjects was not significantly different from that of the late-blind and blindfolded-sighted subjects. In a further experiment, blindfolded subjects drew tangible pictures of three-dimensional (3-D) geometric solids, and then engaged in a matching task. Counter to expectations, performance was not impaired for the 3-D drawings as compared with the frontal viewpoints. Subjects were also especially fast and more accurate when matching top views. Experiment 5 showed that top views were easiest for all of the visually impaired subjects, including those who were congenitally blind. Experiment 5 yielded higher performance for 3-D than frontal viewpoints. The results of all of the experiments were consistent with the idea that visual experience is not necessary for understanding perspective drawings of geometrical objects.     

Social dominance orientation,anti‐egalitarianism and the political psychology of gender: an extension and cross‐cultural replication

This study explored differences in levels of anti‐egalitarianism and social dominance orientation among groups with different social status, and examined the degree to which these differences in anti‐egalitarianism varied across a number of situational and contextual factors. Consistent with both the cultural deterministic (CD) and social dominance (SD) paradigms, when defining social status as socioeconomic status, ethnicity, or ‘race’, differences in anti‐egalitarianism between members of high‐ and low‐status groups were found to be contingent upon a range of contextual and situational factors, such as the degree to which the two groups varied in social status. However, consistent with the SD perspective and the invariance hypothesis, the data also showed that males were more anti‐egalitarian than females, and that this male/female difference in social and group dominance orientation tended to be largely invariant across cultural, situational, and contextual boundaries.

Social dominance orientation: revisiting the structure and function of a variable predicting social and political attitudes

Social dominance orientation (SDO) is one of the most powerful predictors of intergroup attitudes and behavior. Although SDO works well as a unitary construct, some analyses suggest it might consist of two complementary dimensions--SDO-Dominance (SDO-D), or the preference for some groups to dominate others, and SDO-Egalitarianism (SDO-E), a preference for nonegalitarian intergroup relations. Using seven samples from the United States and Israel, the authors confirm factor-analytic evidence and show predictive validity for both dimensions. In the United States, SDO-D was theorized and found to be more related to old-fashioned racism, zero-sum competition, and aggressive intergroup phenomena than SDO-E; SDO-E better predicted more subtle legitimizing ideologies, conservatism, and opposition to redistributive social policies. In a contentious hierarchical intergroup context (the Israeli-Palestinian context), SDO-D better predicted both conservatism and aggressive intergroup attitudes. Fundamentally, these analyses begin to establish the existence of complementary psychological orientations underlying the preference for group-based dominance and inequality.     

Modified test administration using assistive technology: preliminary psychometric findings

This study examined the psychometric properties of test presentation and response formats that were modified to be accessible with the use of assistive technology (AT). First, the stability of psychometric properties was examined in 60 children, ages 6 to 12, with no significant physical or communicative impairments. Population-specific differences were then examined with samples that included 24 children with cerebral palsy and matched control peers. Children were administered standard and modified versions of tests. The type of AT access did not have a statistically significant effect on modified test scores. Measurement stability between the standard and modified versions of quadrant forced-choice format tests was sufficient. The findings support the potential use of AT and accessible procedures for some test instruments in the assessment of children with cerebral palsy.     

Youth-caregiver Agreement on Clinical High-risk Symptoms of Psychosis

Early identification of individuals who will go on to develop schizophrenia is a difficult endeavor. The variety of symptoms experienced by clinical high-risk youth make it difficult to identify who will eventually develop schizophrenia in the future. Efforts are being made, therefore, to more accurately identify at-risk individuals and factors that predict conversion to psychosis. As in most assessments of children and adolescents, however, both youth and parental report of symptomatology and resulting dysfunction are important to assess. The goals of the current study were to assess the extent of cross-informant agreement on the Structured Interview for Prodromal Symptoms (SIPS), a widely-used tool employed to determine clinical high-risk status. A total of 84 youth-caregiver pairs participated. Youth and caregiver raters displayed moderate overall agreement on SIPS-rated symptoms. Both youth and caregiver ratings of youth symptomatology contributed significantly to predicting conversion to psychosis. In addition, youth age and quality of youth-caregiver relationships appear to be related to cross-informant symptom ratings. Despite differences on individual SIPS domains, the majority of dyads agreed on youth clinical high-risk status. Results highlight the potential clinical utility of using caregiver informants to determine youth psychosis risk.     

Focused and fired up: Narrowed attention produces perceived proximity and increases goal-relevant action

Insufficient physical activity contributes to rising obesity rates. We tested one social cognitive strategy aimed at increasing physical activity in the environment. Specifically, we tested whether attentional narrowing can shift people’s perceptual representations of the environment and improve exercise behavior. Participants who adopted a narrow focus of attention, compared to participants who looked around the environment as they naturally would, perceived a target as physically closer (Studies 1, 2). In addition, narrowed attention reduced the time required to walk to a finish line and increased subjective ease of physical task performance, two markers of improved exercise (Study 2). We discuss implications of attentional strategies for perception and action in regards to health and fitness.     

Personality,Motivation, and Internet Gaming Disorder: Conceptualizing the Gamer

Using a group correlational design and path analysis, the authors examined the relationships among personality, motivation, and internet gaming disorder (IGD). Findings showed that significant predictors of IGD included male gender, neurotic and introverted personality traits, and motivation related to achievement.     

Image Theory, Social Identity, and Social Dominance: Structural Characteristics and Individual Motives Underlying International Images

The present study provides an empirical test of international relations image theory and extends the theory by emphasizing that individuals' social identity and social dominance motives contribute to such images. One hundred forty-five Lebanese participants completed a survey that assessed their perceptions of U.S.-Lebanese relations, the images they have of the United States, their social identities, and their social dominance orientations. Participants were more likely to hold the barbarian image of the United States than the enemy, imperialist, or ally images. Participants also tended to perceive the United States as having relatively superior power, inferior cultural status, and goals that are incompatible with those of Lebanon. Consistent with image theory predictions, this constellation of structural perceptions was associated with stronger endorsement of the barbarian image. Furthermore, participants were more likely to endorse the barbarian image of the United States the more they identified with Arabs and Palestinians, the less they identified with Christians and the Western world, and the lower their social dominance orientation. Results highlight the importance of considering both structural characteristics and individual motives underlying international images and demonstrate the need for scholars to move beyond the enemy image of nations when describing international relations.     

Effects of racial diversity on complex thinking in college students

An experiment varying the racial (Black, White) and opinion composition in small-group discussions was conducted with college students (N = 357) at three universities to test for effects on the perceived novelty of group members' contributions to discussion and on participants' integrative complexity. Results showed that racial and opinion minorities were both perceived as contributing to novelty. Generally positive effects on integrative complexity were found when the groups had racial- and opinion-minority members and when members reported having racially diverse friends and classmates. The findings are discussed in the context of social psychological theories of minority influence and social policy implications for affirmative action. The research supports claims about the educational significance of race in higher education, as well as the complexity of the interaction of racial diversity with contextual and individual factors.
