This is the first study to examine the independent, simultaneous, and relative roles of several factors—sex, relationship commitment, perceptions of the benefits vs. costs of cross-sex (vs. same-sex) friendships, gender role orientation, and sexism—in the number of cross-sex (vs. same-sex) friendships people have. The latter four constructs were independently found to predict participants’ proportions of cross-sex friendships. Furthermore, a model comprised of all five factors provided a very good fit to the data, explaining 35% of the variability in the degree to which the participants possessed cross-sex friendships. Perceptions regarding the general benefits of both same- and cross-sex friendships and cross-gender role orientation continued to explain proportion of cross-sex friendship when the other factors were controlled. 相似文献

Fetal alcohol syndrome and the developing socio-emotional brain 总被引:1,自引:0,他引:1

Fetal alcohol syndrome (FAS) is currently recognized as the most common known cause of mental retardation, affecting from 1 to 7 per 1000 live-born infants. Individuals with FAS suffer from changes in brain structure, cognitive impairments, and behavior problems. Researchers investigating neuropsychological functioning have identified deficits in learning, memory, executive functioning, hyperactivity, impulsivity, and poor communication and social skills in individuals with FAS and fetal alcohol effects (FAE). Investigators using autopsy and brain imaging methods have identified microcephaly and structural abnormalities in various regions of the brain (including the basal ganglia, corpus callosum, cerebellum, and hippocampus) that may account for the neuropsychological deficits. Results of studies using newer brain imaging and analytic techniques have indicated specific alterations (i.e., displacements in the corpus callosum, increased gray matter density in the perisylvian regions, altered gray matter asymmetry, and disproportionate reductions in the frontal lobes) in the brains of individuals prenatally exposed to alcohol, and their relations with brain function. Future research, including using animal models, could help inform our knowledge of brain-behavior relations in the context of prenatal alcohol exposure, and assist with early identification and intervention. 相似文献

College student smokers (N = 50) were asked to carry electronic diaries for 14 days and record smoking events (n = 1,139). They indicated why they were smoking each cigarette on a checklist of potential motives. Results suggest that a desire to reduce craving (62.8% of occasions) and habit/automatic processes (42.8%) were the most frequent motives. More dependent and daily smokers were especially likely to endorse smoking to reduce craving and for habit/automatic reasons and were less likely to cite coping with negative emotion as a reason for smoking. Dependent and daily smokers were more likely to endorse at least 1 dependence-like motive and were less likely to exclusively attribute smoking to nondependence motives. Self-monitored motives appeared valid, according with conceptually related states, activities, and events in the diary records. Diary-recorded motives were compared with smokers' responses to a retrospective motives questionnaire administered at baseline. The 2 assessment modes produced discrepant estimates of the most influential motivational processes. Questionnaire responses incompletely forecast conceptually similar diary-reported motives. Dependence and daily smoking showed a different pattern of associations with diary-based versus retrospective motives measures. 相似文献

As antiretroviral therapy (ART) becomes more available in African countries, the potential for interaction with traditional medicines becomes more important. We carried out a cross-sectional survey among individuals with moderate or advanced HIV disease attending a workplace clinic providing ART in South Africa to determine prevalence of traditional medicine use, source, recommended products and costs. Among 44 clinic attendees (100% male, median age 42 years, 30 taking ART), 37 (84%) reported ever using traditional medicines, 25 obtained from a healer or herbalist, eight from their own fields and four from a pharmacy. Fourteen of the 44 (32%) were currently using traditional medicines, most frequently African potato (9/14) and Aloe vera (3/14). Seven out of 30 persons taking ART (23%) reported currently using traditional medicines. Participants spent 4 - 27 pounds per month on traditional medicines. Traditional medicine use is common among individuals with moderate and advanced HIV disease. Concomitant use with ART has the potential for drug interactions and should be discussed routinely in ART counselling. Further work is warranted to investigate whether commonly used traditional medicines interact with ART in vivo. 相似文献

Previous studies demonstrating age-related impairments in recognition memory for faces are suggestive of underlying differences in face processing. To study these differences, we monitored eye movements while younger and older adults viewed younger and older faces. Compared to the younger group, older adults showed increased sampling of facial features, and more transitions. However, their scanning behavior was most similar to the younger group when looking at older faces. Moreover, while older adults exhibited worse recognition memory than younger adults overall, their memory was more accurate for older faces. These findings suggest that age-related differences in recognition memory for faces may be related to changes in scanning behavior, and that older adults may use social group status as a compensatory processing strategy. 相似文献

This study examined the effects of case‐specific facts and individual discomfort with ambiguity (DA) on investigators' beliefs concerning effective interviewing tactics for suspects. Violent crime investigators (n = 30) responded to a questionnaire including the Need for Closure Scale (NFCS) and ratings of the importance of 39 interrogation tactics in two hypothetical interrogations with a homicide suspect, where the evidence consisted of either technical evidence or soft information. Twenty tactics were analysed with a multidimensional scaling procedure which confirmed two discrete interviewing themes: humane and dominant. More tactics, both dominant and humane, were rated as important if the evidence was soft compared with technical. In the soft evidence condition, investigators who were high on DA rated both types of tactics as more important than did low‐DA investigators. In the technical evidence condition, no such difference emerged. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

It is widely held that hearers grasp an utterance's truth conditions by assigning contents to the linguistic expressions used, and combining these contents according to semantic composition rules. To preserve compositionality of truth-conditional content while accounting for context-sensitivity that is not traceable to overt linguistic form, semanticists posit covert linguistic structure. The strongest justification for this approach is the allegedly unconstrained nature of the alternative, whereby a process of 'free pragmatic enrichment' supplies constituents of content that are not traceable to (overt or covert) encoded meaning. This paper argues that free enrichment is tightly constrained by purely pragmatic factors, thus undermining the motivation for semantic compositionality. 相似文献

The study investigated the effects of writing and self-help information on severity of psychological symptoms in traumatic injury patients at risk for developing post-traumatic stress disorder (PTSD). Patients attending Accident and Emergency (A & E), were screened for Acute Stress Disorder and randomised to an information control group (n = 36) or a writing and information group (n = 31). Participants in both groups received an information booklet one-month post-injury. Participants in the writing group also wrote about emotional aspects of their trauma during three 20-min sessions, five to six weeks post-injury. Psychological assessments were completed within one month and at three and six months post-injury. There were significant improvements on measures of anxiety, depression and PTSD over time. Differences between groups on these measures were not statistically significant. However, subjective ratings of the usefulness of writing were high. In conclusion, the results do not currently support the use of writing as a targeted early intervention technique for traumatic injury patients at risk of developing PTSD. 相似文献

A laboratory autonomic conditioning procedure was used to establish fear conditioning in human participants by pairing neutral stimuli with electric shock. Participants were also trained to make a button-press response to avoid shock. A target fear stimulus was then extinguished by presenting it without shock. The experimental group was given the opportunity to make the avoidance response during extinction whereas the control group was not. When the fear stimulus was tested without the response available, the control group showed normal extinction of both shock expectancy ratings and skin conductance responses, but the experimental group showed “protection from extinction”: they continued to give high expectancy ratings and strong skin conductance responses. We interpret this effect as analogous to the role of within-situation safety behaviours in preserving threat beliefs during exposure therapy for anxiety disorders. The results support a cognitive account of learning and anxiety. The procedure provides a potential laboratory model for further examination of the cognitive and neural mechanisms underlying anxiety and its reduction. 相似文献
