Relatively little attention has been paid thus far in memory research to the effects of measurement instruments intended to assess memory processes on the constructs being measured. The current article investigates the influence of employing the popular remember/know (R/K) measurement procedure on memory performance itself. This measurement procedure was extensively used in the past to assess the respective contributions of 2 processes to memory judgments, one based on familiarity and the other on recollection. Two experiments using unrelated word pairs showed that the use of an R/K procedure can alter memory performance. Specifically, the R/K procedure improved associative memory among older but not younger adults compared to conditions in which participants were not asked to provide R/K judgments. Such an effect was not observed in item memory performance. Potential mechanisms mediating these differential memory measurement effects are outlined, and the measurement effects' implications for memory and cognitive research are discussed. 相似文献

Although there is well-documented evidence for hyperactivity of hypothalamic-pituitary-adrenal (HPA) axis function in anorexia nervosa (AN), there has been little research into secretory patterns of salivary cortisol and dehydroepiandrosterone (DHEA) in this condition. The cortisol awakening response (CAR), a prominent and discrete feature of the cortisol cycle, has not been extensively explored in adolescent AN. Saliva samples were collected at awakening, 30?min and 12 h post-awakening on two consecutive weekdays from eight female adolescents with clinically diagnosed AN and 41 healthy control (HC) age-matched females. Adolescent AN patients had greater salivary cortisol and DHEA concentrations than HC girls at all points. Increased hormone secretion was unrelated to body mass index. However, despite hypersecretion of both hormones, the circadian pattern including the CAR paralleled that of the HC group. Findings from this preliminary study confirm dysregulation of HPA axis function in adolescent AN as evidenced by hypersecretion of both cortisol and DHEA, which share the common secretagogue adrenocorticotropic hormone. However, the parallel diurnal profiles for AN and HC participants, including the CAR, may indicate hypersecretion per se rather than differential regulation of the diurnal pattern of these two adrenal steroids in AN. 相似文献

Updated from their original publication in 2004, these cancer genetic counseling recommendations describe the medical, psychosocial, and ethical ramifications of counseling at-risk individuals through genetic cancer risk assessment with or without genetic testing. They were developed by members of the Practice Issues Subcommittee of the National Society of Genetic Counselors Familial Cancer Risk Counseling Special Interest Group. The information contained in this document is derived from extensive review of the current literature on cancer genetic risk assessment and counseling as well as the personal expertise of genetic counselors specializing in cancer genetics. The recommendations are intended to provide information about the process of genetic counseling and risk assessment for hereditary cancer disorders rather than specific information about individual syndromes. Essential components include the intake, cancer risk assessment, genetic testing for an inherited cancer syndrome, informed consent, disclosure of genetic test results, and psychosocial assessment. These recommendations should not be construed as dictating an exclusive course of management, nor does use of such recommendations guarantee a particular outcome. These recommendations do not displace a health care provider's professional judgment based on the clinical circumstances of a client. 相似文献

A deficit in theory of mind (ToM), or the ability to infer the mental states of others, has been implicated as one of the major characteristics of Autism Spectrum Disorder (ASD); however, little attention has been devoted to possible differences in ToM ability within ASD. The current study examined ToM performance in children with early-onset autism and regressive autism in comparison to typically developing children. Results indicated that children in the regressive autism group performed significantly better than the early-onset autism group on the non-verbal appearance-reality task. Additionally, Fisher's exact tests indicated a pattern of lowest scores in the early-onset group and highest scores in the typically developing group, whereas the regressive autism group tended to score in between the early-onset and typically developing groups. The apparent heterogeneity in ToM performance within ASD could account for the lack of universality in ToM ability found in previous studies. 相似文献

Indonesian leadership characteristics were examined in three studies, using mixed methods. In the first, qualitative study 127 indigenous characteristics of Indonesian leadership were identified from interviews and focus group discussions with Indonesian managers and staff. In the second study, a questionnaire based on the characteristics found in the first study was administered to Indonesian managers to identify Indonesian leadership styles. Using factor analysis, two highly correlated dimensions were extracted, labelled benevolent paternalism and transformational leadership. In the third study, a questionnaire consisting of leadership characteristics from the GLOBE study, supplemented with a selection of 49 items from the Indonesian questionnaire, was administered to another sample of Indonesian managers. We found that Indonesian leadership has two components; the first involves a more local modernization dimension that ranges from (traditional) benevolent paternalism to (modern) transformational leadership, the second is a more universal person‐ versus team‐oriented leadership dimension. We conclude that Indonesian leadership has both emic and etic aspects. 相似文献

Classic cognitive theory conceptualizes executive functions as involving multiple specific domains, including initiation,
inhibition, working memory, flexibility, planning, and vigilance. Lesion and neuroimaging experiments over the past two decades
have suggested that both common and unique processes contribute to executive functions during higher cognition. It has been
suggested that a superordinate fronto–cingulo–parietal network supporting cognitive control may also underlie a range of distinct
executive functions. To test this hypothesis in the largest sample to date, we used quantitative meta-analytic methods to
analyze 193 functional neuroimaging studies of 2,832 healthy individuals, ages 18–60, in which performance on executive function
measures was contrasted with an active control condition. A common pattern of activation was observed in the prefrontal, dorsal
anterior cingulate, and parietal cortices across executive function domains, supporting the idea that executive functions
are supported by a superordinate cognitive control network. However, domain-specific analyses showed some variation in the
recruitment of anterior prefrontal cortex, anterior and midcingulate regions, and unique subcortical regions such as the basal
ganglia and cerebellum. These results are consistent with the existence of a superordinate cognitive control network in the
brain, involving dorsolateral prefrontal, anterior cingulate, and parietal cortices, that supports a broad range of executive
functions. 相似文献

Integrating the multisensory features of talking faces is critical to learning and extracting coherent meaning from social signals. While we know much about the development of these capacities at the behavioral level, we know very little about the underlying neural processes. One prominent behavioral milestone of these capacities is the perceptual narrowing of face–voice matching, whereby young infants match faces and voices across species, but older infants do not. In the present study, we provide neurophysiological evidence for developmental decline in cross‐species face–voice matching. We measured event‐related brain potentials (ERPs) while 4‐ and 8‐month‐old infants watched and listened to congruent and incongruent audio‐visual presentations of monkey vocalizations and humans mimicking monkey vocalizations. The ERP results indicated that younger infants distinguished between the congruent and the incongruent faces and voices regardless of species, whereas in older infants, the sensitivity to multisensory congruency was limited to the human face and voice. Furthermore, with development, visual and frontal brain processes and their functional connectivity became more sensitive to the congruence of human faces and voices relative to monkey faces and voices. Our data show the neural correlates of perceptual narrowing in face–voice matching and support the notion that postnatal experience with species identity is associated with neural changes in multisensory processing ( Lewkowicz & Ghazanfar, 2009 ). 相似文献

Body image disturbance is frequent among individuals undergoing cosmetic surgery and core to the pathology of eating disorders (ED); however, there is little research examining cosmetic surgery in ED. This study examined body image related measures, ED behaviors, and depression as predictors of attitudes toward cosmetic surgery in 129 women with ED. Patients who had undergone surgery (n = 16, 12%) were compared to those who had not. Having a purging diagnosis, linking success to appearance, and making physical appearance comparisons were predictive of more favorable cosmetic surgery attitudes. All of those who had undergone surgery had purging diagnoses and, on average, were older, had higher BMIs, and were more likely to make physical appearance comparisons and know someone who had undergone surgery. In ED, acceptance and pursuit of cosmetic surgery appears to be related to social group influences more than weight and shape disturbance, media influences, or mood. 相似文献
