This research examined preferences for national- and campus-level assimilative and pluralistic policies among Black and White students under different contexts, as majority- and minority-group members. We targeted attitudes at two universities, one where 85% of the student body is White, and another where 76% of students are Black. The results revealed that when a group constituted the majority, its members generally preferred assimilationist policies, and when a group constituted the minority, its members generally preferred pluralistic policies. The results support a functional perspective: Both majority and minority groups seek to protect and enhance their collective identities. 相似文献

Self-mastery refers to problem-focused coping facilitated through personal agency. Communal mastery describes problem solving through an interwoven social network. This study investigates an adaptation of self- and communal mastery measures for youth. Given the important distinction between family and peers in the lives of youth, these adaptation efforts produced Mastery-Family and Mastery-Friends subscales, along with a Mastery-Self subscale. We tested these measures for psychometric properties and internal structure with 284 predominately Yup'ik Eskimo Alaska Native adolescents (12- to 18-year-olds) from rural, remote communities-a non-Western culturally distinct group hypothesized to display higher levels of collectivism and communal mastery. Results demonstrate a subset of items adapted for youth function satisfactorily, a 3-response alternative format provided meaningful information, and the subscale's underlying structure is best described through 3 distinct first-order factors organized under 1 higher order mastery factor. 相似文献

Fragile X syndrome (FXS) is an inherited genetic condition with critical consequences to the proband and family members at all levels in the generations. Although evidence demonstrates that the rates of diagnosis for FXS are the same in all racial groups, age of diagnosis in African American children has been reported to occur later than in Caucasian children. Additionally, African American families are seriously under-represented in existing FXS research studies. As such, it is important to understand the possible disparities in the underlying factors to receiving a diagnosis in African American families with FXS. Herein, a qualitative approach was adopted to describe the overall FXS diagnosis experiences (pre-diagnosis, diagnosis, and post-diagnosis stages) of a convenience sample of 10 African American mothers. We identified three major findings among our participants: (1) FXS testing is not ordered immediately once a parent expresses concerns of developmental delays to the pediatricians, (2) the diagnosis is sometimes delivered in an insensitive manner with information often being outdated and unbalanced towards negative aspects, (3) communication issues among family members exists once the diagnosis is discovered. Although these qualitative data may not be representative of the whole group, these findings have significant implications for genetic counseling and our understanding in providing support and advocacy for African American families with FXS. 相似文献

Researchers have argued that the investigation of causal interrelationships between symptoms may help explain the high comorbidity rate between certain psychiatric disorders. Clients' own attributions concerning the causal interrelationships linking the co-occurrence of their symptoms represent data that may inform their clinical case conceptualization, treatment, and psychological theory regarding the etiology of comorbid disorders. The present study developed and evaluated a novel psychological assessment methodology for measuring Perceived Causal Relations (PCR) and examined its psychometric properties as applied to the question of whether posttraumatic stress and anxiety symptoms represent causal risk factors for depressive symptoms in 225 undergraduates. Participants attributed their symptoms of anxiety and posttraumatic reexperiencing as significant causes of their depressive symptoms. Exploratory analyses identified a listing of symptoms reliably attributed as significant causes of other symptoms and functional impairment, as well as a listing of symptoms reliably attributed as significant effects (outcomes) of other symptoms and functional impairment. The PCR method has promise as an idiographic approach to assessing the causes and consequences of comorbid psychiatric symptoms and associated functional impairment. Research is required to assess the relevance and replicate these findings in distinct psychiatric groups experiencing various symptomatic presentations. Future research may also examine PCR ratings associating other individual differences, for example, between measures of history (e.g., life events), life choices, and personality. 相似文献

Although significant advances in our understanding of the cognitive and neural processes involved in conscious awareness have occurred in recent years, the precise mechanisms that support consciousness remain elusive. Examining the neural correlates associated with the moment a stimulus enters or exits conscious awareness is one way to potentially identify the neural mechanisms that give rise to consciousness. In the present study, we recorded neural activity using electroencephalography (EEG) while participants observed a bilateral shape-from-motion (SFM) display. While the display is in motion, the observer perceives an object that is immediately segregated from a noisy background. After the motion stops, the observer's experience of the object remains momentarily in awareness, before it eventually fades out of consciousness back into the noisy background. Consistent with subjective reports of perceptual experience, we observed a prominent sustained posterior contralateral negativity known as the contralateral delay activity (CDA). This activity was sustained only in conditions associated with sustained awareness. Interestingly, the amplitude of the CDA was correlated with individual differences in visual awareness, suggesting that this activity plays a significant role in the maintenance of objects in consciousness. The CDA is typically associated with visual short-term memory (VSTM), suggesting that conscious visual awareness may be mediated by the same neural and cognitive mechanisms that support VSTM. Our results demonstrate that the CDA may reflect the contents of conscious awareness, and therefore can provide a measure to track when information moves in and out of consciousness. 相似文献

People who know the outcome of an event tend to overestimate their own prior knowledge or others' na?ve knowledge of it. This hindsight bias pervades cognition, lending the world an unwarranted air of inevitability. In four experiments, we showed how knowing the identities of words causes people to overestimate others' na?ve ability to identify moderately to highly degraded spoken versions of those words. We also showed that this auditory hindsight bias occurs despite people's efforts to avoid it. We discuss our findings in the context of communication, in which speakers overestimate the clarity of their message and listeners overestimate their understanding of the message. 相似文献

The learning of new information and recall of that information presumably involves modification of and access to shared circuitry in the brain. However, learning and recall may involve the activation of distinct parts of that circuitry, according to the quite distinct functional differences between these two processes. Previously we examined neuronal activation following learning of context fear conditioning. Using the Fos-Tau-LacZ (FTL) transgenic mouse to label activated neurons, we identified a number of distinct populations of neurons in amygdala and hypothalamus which showed learning specific activation. These populations of neurons showed much less activation following recall. Here we ask what populations of neurons might be specifically activated following recall. We trained mice in context fear conditioning, and then looked at FTL activation following recall of context fear. We identified a number of populations of neurons which showed recall specific activation in nucleus accumbens shell, the anterio-medial bed nucleus of stria terminalis, the anterior commissural nucleus and the periventricular hypothalamic nucleus. These were all different populations of neurons compared with those activated following context fear learning. These different functional activation patterns occurring between learning and recall may reflect the different brain functions occurring between these two memory related processes. 相似文献

Objectives
To examine quantity of exercise and motives for exercise as predictors of men in the military’s health and fitness level.Design
Participants completed a survey to address research questions of interest.Methods
One-hundred and fourteen men who were active duty Air Force members, with a mean age of 31.43 years (SD = 7.43) and an average military time in service of 10.66 years (SD = 7.75), completed a modified version of the Reasons for Exercise Inventory, a survey assessing their quantity of exercise, and reported their most recent score on their Air Force Fitness Test.Results
Correlational analyses indicated a relation between quantity of exercise and men’s score on the Air Force Fitness Test and a relation between intrinsic motives for exercise and quantity of exercise. Intrinsic motivation was found to moderate the relation between quantity of exercise and men’s health and fitness score.Conclusions
Men in the military who exercise because of their military obligation are less likely to score high on the Air Force Fitness Test than are men who are motivated to exercise for health benefits. 相似文献940.
The purpose of this study was to examine self-regulation as a mediator of the relation between family functioning and externalizing behaviour in 731 low-income children (M age = 41 months) across three time points. Specifically, this study focused on whether chaos in the home and positive behaviour support were indirectly related to externalizing problems through their influence on inhibitory control. The primary findings were as follows: (a) chaos in the home at age 3 years was indirectly related to externalizing behaviour at age 5.5 years through children's inhibitory control at age 4 years, and (b) positive behaviour support at age 3 years was indirectly related to externalizing behaviour at age 5.5 years through inhibitory control at age 4 years. Implications of these findings and directions for future research are discussed. 相似文献
