The association between homelessness and suicidal ideation and behaviors: results of a cross-sectional survey

This study was carried out with three goals: (1) to determine the prevalence of suicidal ideation and suicide attempts among the homeless; (2) to determine what aspects of homelessness predict suicidality, and (3) to determine which aspects remain predictive after controlling for key covariates, such as mental illness. A sample of 330 homeless adults were interviewed. Sixty-one percent of the study sample reported suicidal ideation and 34% had attempted suicide. Fifty-six percent of the men and 78% of the women reported prior suicidal ideation, while 28 percent of the men and 57% of the women had attempted suicide. Childhood homelessness of at least 1 week without family members and periods of homelessness longer than 6 months were found to be associated with suicidal ideation. Psychiatric diagnoses were also associated with suicidality in this sample.     

The Role of Life Stress and Social Support in the Adjustment of Sexually Victimized Pregnant and Parenting Minority Adolescents

Associations among sexual victimization and the psychosocial functioning of African American and Latina pregnant and parenting adolescents were examined. Forty-seven (17.7%) of the 265 participants reported histories of sexual victimization, most of which was unwanted sexual intercourse. The victimized adolescents reported higher levels of depression, anxiety, and life stress and, although the two groups reported no differences in their levels of social support, support was found to be differentially related to depression and anxiety in the two groups. In particular, victims derived benefits from social support at low levels of stress, but social support provided no protection against depression and anxiety at average or high levels of stress. For nonvictims, social support provided no benefits at low levels of stress, but protected against depression and anxiety at moderate levels of stress and against depression at high levels of stress. Implications of these findings for research, theory, and intervention are discussed.     

“Just another pretty face”: A multidimensional scaling approach to face attractiveness and variability

Findings on both attractiveness and memory for faces suggest that people should perceive more similarity among attractive than among unattractive faces. A multidimensional scaling approach was used to test this hypothesis in two studies. In Study 1, we derived a psychological face space from similarity ratings of attractive and unattractive Caucasian female faces. In Study 2, we derived a face space for attractive and unattractive male faces of Caucasians and non-Caucasians. Both studies confirm that attractive faces are indeed more tightly clustered than unattractive faces in people’s psychological face spaces. These studies provide direct and original support for theoretical assumptions previously made in the face space and face memory literatures.     

The effects of movement direction and hemispace on estimates of distance traveled

BACKGROUND/HYPOTHESIS: The degree of attention directed to a stimulus and the presence of anisometric representations can alter the perception of the magnitude of a stimulus. We wanted to learn if normal right-handed subjects' estimates of distance traveled are influenced by the right-left direction or hemispace of movements. METHODS: We had blindfolded participants estimate the distance their arm was moved in a rightward or leftward direction, in right and left hemispace. Since we wanted subjects to estimate the distance traveled rather than compute the distance between the start and finish points, the subjects' arms were passively moved in sinusoidal trajectories at a constant speed. RESULTS: Subjects estimated leftward movements as longer than rightward movements, but there was no effect of hemispace. COMMENTS/CONCLUSIONS: People often attend more to novel than routine conditions and therefore participants might have overestimated the distance associated with leftward versus rightward movement because right-handed people more frequently move their right hand in a rightward direction and learn to read and write using rightward movements. Thus, leftward movements might be more novel and more attended than rightward movements and this enhanced directional attention might have influenced estimates of magnitude (distance).     

Familiar other-race faces show normal holistic processing and are robust to perceptual stress

Other-race individuals are remembered more poorly and receive less holistic/configural processing than same-race individuals, at least when faces are novel. Here, we examine the amelioration of these effects with familiarity, using distinctiveness-matched Caucasian and Asian stimulus sets. We confirmed a cross-race deficit for upright faces following a single encoding trial, which disappeared rapidly with practice on a small set of other-race 'friends' and did not re-emerge when perceptual processing was put under stress (presentation in the periphery). We also examined holistic/configural processing for familiarised faces using the peripheral inversion effect (McKone, 2004 Journal of Experimental Psychology: Learning, Memory, and Cognition 30 181 - 197). A test for faces and nonface objects (dogs) confirmed the validity of this technique as providing a direct measure of holistic processing; we then showed that, after 1 h of training, holistic processing was as strong for other-race as same-race faces. We conclude that practice with other-race individuals can rapidly engage normal face-processing mechanisms.     

Preschoolers Use Social Allegiances to Predict Behavior

Developing mechanisms for predicting human action is a critical task of early conceptual development. Three studies examined whether 4-year-old children (N = 149) use social allegiances to predict behavior, by testing whether they expect the experiences of social partners to influence individual action. After being exposed to a conflict between two individuals from different novel social categories, children reliably predicted that another member of one category would withhold friendship from the contrasting category (Studies 1 and 2) and direct harmful actions toward the contrasting category (Study 3). Children did so even when the initial conflict had no direct implications for the other category members, and even when they knew that the two social categories had a positive relationship in the past. These data show that young children view social categories as marking people who are obligated to one another, and thus use the experiences of allegiance partners to predict how individuals will behave.

Examining the influence of anecdotal stories and the interplay of individual differences on reasoning

In two experiments, we explored whether anecdotal stories influenced how individuals reasoned when evaluating scientific news articles. We additionally considered the role of education level and thinking dispositions on reasoning. Participants evaluated eight scientific news articles that drew questionable interpretations from the evidence. Overall, anecdotal stories decreased the ability to reason scientifically even when controlling for education level and thinking dispositions. Additionally, we found that article length was related to participants' ratings of the news articles. Our study demonstrates that anecdotes can discourage scientific reasoning while also pointing to the potential influence of article length on judgements of quality.
