The following study examined the reactions of university students to Hurricane Katrina. A group of 68 New Orleans area students who were displaced from their home universities as a result of the hurricane were matched on race, gender, and age to a sample of 68 students who had been enrolled at Louisiana State University (LSU) prior to the hurricane. All students were enrolled at LSU at the time they participated in an online survey, conducted 3 months following the hurricane. The survey included symptom measures of depression, anxiety, stress, posttraumatic stress disorder (PTSD), and other variables. Results indicated displaced students experienced more trauma exposure and greater subsequent distress, more symptoms of PTSD, and more symptoms of depression. Moreover, traumatic exposure and distress from the traumatic exposure were found to fully mediate depressive symptoms and posttraumatic symptoms in the displaced students. 相似文献

The current study presents a method for assessing the relative effects of attention and escape on noncompliance in preschoolers. Attention and escape conditions were alternated in a multielement design, and a contingency reversal procedure, in which one test condition served as a control for the other, was used to demonstrate control. For all 3 participants, noncompliance was maintained, at least in part, by social attention. Functional analyses of noncompliance such as the one described here may be valuable for developing function‐based treatments. 相似文献

Numeric magnitudes often bias adults’ spatial performance. Partly because the direction of this bias (left‐to‐right versus right‐to‐left) is culture‐specific, it has been assumed that the orientation of spatial‐numeric associations is a late development, tied to reading practice or schooling. Challenging this assumption, we found that preschoolers expected numbers to be ordered from left‐to‐right when they searched for objects in numbered containers, when they counted, and (to a lesser extent) when they added and subtracted. Further, preschoolers who lacked these biases demonstrated more immature, logarithmic representations of numeric value than preschoolers who exhibited the directional bias, suggesting that spatial‐numeric associations aid magnitude representations for symbols denoting increasingly large numbers. 相似文献

North Americans live in an increasingly fast-paced world. Not only might this be physically and relationally unhealthy, a
fast pace of life might prevent people from living life to its fullest and achieving happiness. Using Heidegger’s theory of
Dasein, this study examines how individuals talk about time in holiday letters. Results of the study indicate that many letter
writers were living inauthentic lives. According to Heidegger, inauthenticity prevents individuals from experiencing life
at its fullest; implications of the findings blending philosophy and communication are discussed. 相似文献

When the cost of altruism is low, individuals are more likely to help non-kin (i.e., friends and romantic partners) than kin. This trend is thought to reflect the fact that people tend to be emotionally closer with friends and romantic partners than kin. However, as the cost of altruism increases, altruistic preference shifts to kin. The present study highlights this phenomenon by examining altruism between siblings, romantic partners, romantic partners who have biological children together, and romantic partners who have adopted children together. Participants (n = 203) completed a questionnaire about altruism in low-, medium-, and high-cost situations. Participants gave more low-cost help to their romantic partners (regardless of whether they had a child together) than their siblings. More medium-cost help was given to romantic partners who had a child (biological and adopted) than siblings and romantic partners without children. In the high-cost condition, the estimated altruistic tendencies were stronger toward siblings and romantic partners who have a biological child than toward romantic partners with no children and partners with adopted children. Participants also believed they were more altruistic than their siblings and romantic partners. 相似文献

Following a model that is inclusive of both dispositional and situational influences on life-history behaviors and attitudes, the effect of life expectancies on aggression and generativity was examined. Consistent with the hypotheses it was found that shorter life expectancies led to an increase in the desire to aggress and a decrease in the desire to engage in generative behaviors. The results are discussed in terms of how life history theory can be used to frame research on person-situation interactions. 相似文献

In four experiments, we examined whether facial expressions used while singing carry musical information that can be “read”
by viewers. In Experiment 1, participants saw silent video recordings of sung melodic intervals and judged the size of the
interval they imagined the performers to be singing. Participants discriminated interval sizes on the basis of facial expression
and discriminated large from small intervals when only head movements were visible. Experiments 2 and 3 confirmed that facial
expressions influenced judgments even when the auditory signal was available. When matched with the facial expressions used
to perform a large interval, audio recordings of sung intervals were judged as being larger than when matched with the facial
expressions used to perform a small interval. The effect was not diminished when a secondary task was introduced, suggesting
that audio-visual integration is not dependent on attention. Experiment 4 confirmed that the secondary task reduced participants’
ability to make judgments that require conscious attention. The results provide the first evidence that facial expressions
influence perceived pitch relations. 相似文献

This paper describes 2 studies that evaluated a new instrument, the Perceived Ethnic Discrimination Questionnaire‐Community Version (PEDQ‐CV). The PEDQ‐CV can be used across ethnic groups to assess perceived racism or ethnic discrimination. The scales measure several subdimensions of racism, permitting the examination of different forms of this race‐related stressor. The first study evaluated the psychometric properties of the PEDQ‐CV in a large sample of community‐dwelling adults. The second evaluated psychometric properties of a brief version of the PEDQ‐CV, developed for research protocols requiring a shorter administration time. Tests were made of reliability and several forms of construct validity. Both versions of the PEDQ‐CV have good reliability and construct validity. The PEDQ‐CV can facilitate the development of an integrative body of knowledge across different ethnic groups regarding the existence, determinants, and consequences of discrimination. 相似文献

In order to investigate the relatively new phenomenon of male body depilation, 118 male university students provided details regarding the reduction and removal of their body hair using a questionnaire developed from the results of structured interviews (Boroughs & Thompson, 2002). It was found that well over one-half of the sample (63.6%) was engaged in body depilation (i.e., the reduction or removal of body hair below the neck). The sites, methods, reasons, and injuries related to body depilation were assessed, as well as its effect on affective dimensions. Findings are considered in light of these ramifications and how they may contribute to a better understanding of men’s body image. 相似文献
