The sex difference in jealousy is an effect that has generated significant controversy in the academic literature (resulting in two meta-analyses that reached different conclusions on the presence or absence of the effect). In this study, we had a team of researchers from different theoretical perspectives use identical protocols to test whether the sex difference in jealousy would occur across many different samples (while testing whether mate value would moderate the effect). In our samples, we found the sex difference in jealousy to occur using both forced choice and continuous measures, this effect appeared in several different settings, and, we found that mate value moderated participant responses. The results are discussed in light of the controversy surrounding the presence of the effect. 相似文献

Despite implications that stranger fear is an important aspect of developing behavioral inhibition, a known risk factor for anxiety, normative and atypical developmental trajectories of stranger fear across infancy and toddlerhood remain understudied. We used a large, longitudinal data set (N = 1285) including multi‐trait, multi‐method assessments of temperament to examine the normative course of development for stranger fear and to explore the possibility that individual differences exist in trajectories of stranger fear development between 6 and 36 months of age. A latent class growth analysis suggested four different trajectories of stranger fear during this period. Stable, high levels of stranger fear over time were associated with poorer RSA suppression at 6 months of age. Rates of concordance in trajectory‐based class membership for identical (monozygotic) and fraternal (dizygotic) twins, along with associations between atypical stranger fear development and greater anxiety‐related maternal characteristics, suggested that individual differences in developmental trajectories of stranger fear may be heritable. Importantly, trajectories of stranger fear during infancy and toddlerhood were linked to individual differences in behavioral inhibition, with chronically high levels of stranger fear and sharp increases in stranger fear over time related to greater levels of inhibition than other developmental trajectories. 相似文献

This study was designed to investigate choice of role models and levels of self-esteem within a sample of college students (N = 120). Participants rated themselves and their chosen role models on 29 character traits, which allowed determination of the self-perceived likeness of the participant to their role models (difference score). The difference score was then correlated with four subtypes of self-esteem. As predicted, participants chose more same-sex than other-sex role models; women were more likely than men to choose other-sex role models. The results indicated that choice of same-sex, as opposed to other-sex role models, is not indicative of higher levels of self-esteem in general. However, self-perceived likeness of role model to participant is significantly related to self-esteem, particularly for women. 相似文献

College graduates and employers alike have expressed dissatisfaction with the lack of job competencies of new graduates. Both groups suggest that institutions of higher education must do a better job of preparing their students to meet workplace challenges. The author describes the problem and presents a model that is delivered via distance education at one university. One of the major goals of the program presented is to ease the transition of college graduates to the workforce. The practical suggestions are appropriate for practitioners who work with this population, and they can be adapted for individual or group counseling. 相似文献

Are abstract representations of number – representations that are independent of the particular type of entities that are enumerated – a product of human language or culture, or do they trace back to human infancy? To address this question, four experiments investigated whether human infants discriminate between sequences of actions (jumps of a puppet) on the basis of numerosity. At 6 months, infants successfully discriminated four‐ versus eight‐jump sequences, when the continuous variables of sequence duration, jump duration, jump rate, jump interval and duration, and extent of motion were controlled, and rhythm was eliminated. In contrast, infants failed to discriminate two‐ versus four‐jump sequences, suggesting that infants fail to form cardinal number representations of small numbers of actions. Infants also failed to discriminate between sequences of four versus six jumps at 6 months, and succeeded at 9 months, suggesting that infants’ number representations are imprecise and increase in precision with age. All of these findings agree with those of studies using visual–spatial arrays and auditory sequences, providing evidence that a single, abstract system of number representation is present and functional in infancy. 相似文献

The Physical Appearance Ambiguous Feedback Scale (PAAFS): a measure for indexing body image related cognitive bias 总被引:1,自引:0,他引:1
Recent conceptualizations of body image disturbance have included an information processing model that includes a focus on an interpretive information processing bias. Study 1 involved the development and validation of a measure of appearance-based cognitive bias, the Physical Appearance Ambiguous Feedback Scale (PAAFS). In Studies 2 and 3, two samples of college females (n=313) were tested and the psychometric characteristics of the PAAFS were evaluated. Reliability was acceptable and convergence with measures of body image and eating disturbance was moderate. In Study 4, 313 college females completed the PAAFS in the laboratory based on an instructional content designed to induce processing bias. Preliminary evidence indicates that the PAAFS appears to be sensitive to instructional set manipulations and dispositional level of body dissatisfaction. 相似文献

We used the Balloon Analog Risk Task (BART) to examine risk taking and sensitivity to punishment, two relevant aspects of
behavioral inhibition, in 203 school-age children with attention-deficit/hyperactivity disorder (ADHD), oppositional defiant
disorder (ODD), ADHD+ODD, and controls. Participants earned points on the BART by pumping 30 separate balloons that exploded
at variable intervals. No points were earned on a trial when a balloon exploded. The number of pumps across all balloons estimated
risk taking and the reduction in pumps following balloon explosions was interpreted as an indicator of sensitivity to negative
punishment. We found that all groups significantly differed from one another on risk taking. The ADHD+ODD group pumped the
most, followed by the ODD, ADHD, and the control group, respectively. For sensitivity to negative punishment, all groups performed
differently, with the ODD group showing the least sensitivity to an exploded balloon, followed by the ADHD, control, and ADHD+ODD
groups, respectively. Children with ADHD+ODD demonstrated significantly different patterns of risk taking and sensitivity
to negative punishment than children with either ADHD-only or ODD-only. ADHD youth with comorbid ODD had the greatest levels
of risk taking, but they were also the most sensitive to negative punishment. The relationship between ADHD and ODD, as well
as the nature of comorbidity in constructs related to risk taking and related behaviors, are discussed. 相似文献

If there is a spider in the room, then the spider phobic in your group is most likely to point it out to you. This phenomenon is believed to arise because our attentional systems are hardwired to attend to threat in our environment, and, to a spider phobic, spiders are threatening. However, an alternative explanation is simply that attention is quickly drawn to the stimulus of most personal relevance in the environment. Our research examined whether positive stimuli with no biological or evolutionary relevance could be allocated preferential attention. We compared attention to pictures of spiders with pictures from the TV program Doctor Who, for people who varied in both their love of Doctor Who and their fear of spiders. We found a double dissociation: interference from spider and Doctor-Who-related images in a visual search task was predicted by spider fear and Doctor Who expertise, respectively. As such, allocation of attention reflected the personal relevance of the images rather than their threat content. The attentional system believed to have a causal role in anxiety disorders is therefore likely to be a general system that responds not to threat but to stimulus relevance; hence, nonevolutionary images, such as those from Doctor Who, captured attention as quickly as fear-relevant spider images. Where this leaves the Empress of Racnoss, we are unsure. 相似文献

This study examined the association between childhood ADHD and juvenile delinquency by examining data from the Pittsburgh
ADHD Longitudinal Study (PALS), a follow-up study of individuals diagnosed with ADHD in childhood (ages 5–12) and recontacted
in adolescence and young adulthood for yearly follow-up (age at first follow-up interview M = 17.26, SD = 3.17). Participants were 288 males with childhood ADHD and 209 demographically similar males without ADHD who were recruited
into the follow-up study. Delinquency information gathered yearly during the second through eighth follow-up provided a comprehensive
history of juvenile delinquency for all participants. Four childhood diagnostic groups [ADHD-only (N = 47), ADHD + ODD (N = 135), ADHD + CD (N = 106), and comparison (N = 209)] were used to examine group differences on delinquency outcomes. Analyses were conducted across three dimensions of
delinquency (i.e., severity, age of initiation, and variety). Individuals with childhood ADHD + CD displayed significantly
worse delinquency outcomes than the other three groups, across almost all indices of offending. When compared to comparison
participants, boys with ADHD-only and ADHD + ODD in childhood displayed earlier ages of delinquency initiation, a greater
variety of offending, and higher prevalence of severe delinquency. These findings suggest that although childhood ADHD + CD
creates the greatest risk for delinquency, boys with ADHD-only and ADHD + ODD also appear at a higher risk for later offending.
The patterns of offending that emerged from the PALS are discussed in the context of the relationship between ADHD, comorbidity,
and delinquency. 相似文献
