A scale of prejudice against transgender individuals was developed, validated, and contrasted with a homophobia measure in 153 female and 157 male US college undergraduates. For both sexes, transphobia and homophobia were highly correlated with each other and with right-wing authoritarianism, religious fundamentalism, and hostile sexism, but aggression proneness was predictive of transphobia and homophobia only in men. Benevolent sexism and rape myth acceptance were more predictive of transphobia and homophobia in women than men. With homophobia partialled out, authoritarianism, fundamentalism, and aggression proneness no longer predicted transphobia for men, but authoritarianism, fundamentalism, benevolent sexism, and rape myth acceptance continued to predict transphobia in women. Discussion focused on gender differences in issues that drive prejudice against transgender and homosexual individuals. 相似文献

Meta-analysis of studies assessing the comorbidity of somatization disorder (SD) with one or more personality disorders (PDs)
revealed that-contrary to the assertions of the Diagnostic and Statistical Manual of Mental Disorders (4th edition, text revision)-SD co-occurs with the majority of Axis II PDs. Although comorbidity effect sizes (rs) linking SD with paranoid PD and obsessive-compulsive PD were small, effect sizes for antisocial, borderline, narcissistic,
histrionic, avoidant, and dependent PD yielded rs about or above 0.20. Comorbidity information in future versions of the DSM should be revised to reflect the greater number
of PDs empirically linked with SD.

This study examined how rumors originating in 3- to 6-year-olds' causal inferences can affect their own and their peers' memories for a personally experienced event. This was accomplished by exposing some members of classrooms to contextual clues that were designed to induce inferences about the causes of two unresolved components of the event. After a 1-week delay, a substantial number of children who were exposed to the clues misremembered their inferences as actual experiences. Causal inferential memory errors were most pronounced among 5- and 6-year-olds. Also, many of the children whose classmates were exposed to the clues mistakenly incorporated their classmates' causal inferences into their own accounts, with 3- and 4-year-olds being most likely to make this error. 相似文献

Operant conditioning with Betta splendens (Bettas) has been investigated extensively using males of the species. Ethological studies of female Bettas have revealed aggressive interactions that qualitatively parallel those between male Bettas. Given these similarities, four experiments were conducted with female Bettas to examine the generality of a widely reported finding with males: mirror-image reinforcement. Swimming through a ring was reinforced by a 10-s mirror presentation. As with males, ring swimming was acquired and maintained when mirror presentations were immediate (Experiments 1, 2, and 3) and delayed (Experiment 4). The failure of conventional extinction (Experiments 1 and 2) and response-independent mirror presentations (Experiment 3) to maintain responding confirmed the reinforcing properties of mirror presentation. These results extend previous findings of mirror images as reinforcers in males of the same species and illustrate a complementarity between behavioral ecology and the experimental analysis of behavior. 相似文献

As an individual’s understanding of their genetic risk may influence risk management decisions, it is important to understand
the ways in which risk is constructed and interpreted. We systematically reviewed the literature, undertaking a narrative synthesis
of 59 studies presenting data on the ways in which individuals perceive, construct and interpret their risk, and the subsequent
effects. While most studies assessed perceived risk quantitatively, the combined evidence suggests individuals find risk difficult
to accurately quantify, with a tendency to overestimate. Rather than being a stand-alone concept, risk is something lived
and experienced and the process of constructing risk is complex and influenced by many factors. While evidence of the effects
of perceived risk is limited and inconsistent, there is some evidence to suggest high risk estimations may adversely affect
health and lead to inappropriate uptake of medical surveillance and preventative measures by some individuals. A more focused
approach to research is needed with greater exploration of the ways in which risk is constructed, along with the development
of stronger theoretical models, to facilitate effective and patient-centered counseling strategies. 相似文献

Spinal cord neurons can support a simple form of instrumental learning. In this paradigm, rats completely transected at the second thoracic vertebra learn to minimize shock exposure by maintaining a hindlimb in a flexed position. Prior exposure to uncontrollable shock (shock independent of leg position) disrupts this learning. This learning deficit lasts for at least 24h and depends on the NMDA receptor. Intrathecal application of an opioid antagonist blocks the expression, but not the induction, of the learning deficit. A comparison of selective opioid antagonists implicated the kappa-opioid receptor. The present experiments further explore how opioids affect spinal instrumental learning using selective opioid agonists. Male Sprague-Dawley rats were given an intrathecal injection (30 nmol) of a kappa-1 (U69593), a kappa-2 (GR89696), a mu (DAMGO), or a delta opioid receptor agonist (DPDPE) 10 min prior to instrumental testing. Only the kappa-2 opioid receptor agonist GR89696 inhibited acquisition (Experiment 1). GR89696 inhibited learning in a dose-dependent fashion (Experiment 2), but had no effect on instrumental performance in previously trained subjects (Experiment 3). Pretreatment with an opioid antagonist (naltrexone) blocked the GR89696-induced learning deficit (Experiment 4). Administration of GR89696 did not produce a lasting impairment (Experiment 5) and a moderate dose of GR89696 (6 nmol) reduced the adverse consequences of uncontrollable nociceptive stimulation (Experiment 6). The results suggest that a kappa-2 opioid agonist inhibits neural modifications within the spinal cord. 相似文献

Adolescence is a period of life in which the sense of 'self' changes profoundly. Here, we review recent behavioural and neuroimaging studies on adolescent development of the self-concept. These studies have shown that adolescence is an important developmental period for the self and its supporting neural structures. Recent neuroimaging research has demonstrated that activity in brain regions associated with self-processing, including the medial prefrontal cortex, changes between early adolescence and adulthood. These studies indicate that neurocognitive development might contribute to behavioural phenomena characteristic of adolescence, such as heightened self-consciousness and susceptibility to peer influence. We attempt to integrate this recent neurocognitive research on adolescence with findings from developmental and social psychology. 相似文献

We examined the effects of professor reputation versus first impressions on student evaluations of instruction. Students in
19 Psychology courses completed course evaluation surveys either before meeting the instructor or 2 weeks into the semester.
Both groups then completed the course evaluation again at the end of the semester. Unlike evaluations completed prior to meeting
the professor, students’ ratings 2 weeks into the semester did not differ from end-of-semester evaluations. Therefore, students
considered first impressions more important than professor reputation as determinants of their end-of-the semester evaluations.
Results suggest that students form lasting impressions within the first 2 weeks of classes.
