Male breast cancer is a serious issue that needs to be addressed more fully by the medical and public community. However,
due to a lack of awareness and limited research on the topic, there is a general absence of knowledge concerning the psychological
implications of this disease in men as well as a need for greater understanding of the medical diagnosis and treatment of
male breast carcinoma. Similarly, there still remains a considerable gender difference between the awareness of female breast
cancer and male breast cancer Although breast cancer in men makes up only 1% of all breast cancers reported in the United
States, it is increasing in incidence. There are approximately 2000 new cases and approximately 450 deaths due to male breast
cancer each year. Breast cancer diagnosis and treatment in men is very similar to that described in women, however, it has
been shown that men are being diagnosed at a later stage of the disease than women. 相似文献

In a recognition memory test, subjects may be asked to decide whether a test item is old or new (item recognition) or to decide among alternative sources from which it might have been drawn for study (source recognition). Confidence-rating-based receiver operating characteristic (ROC) curves for these superficially similar tasks are quite
different, leading to the inference of correspondingly different decision processes. A complete account of source and item
recognition will require a single model that can be fit to the entire data set. We postulated a detection-theoretic decision
space whose dimensions, in the style of Banks (2000), are item strength and the relative strengths of the two sources. A model
that assumes decision boundaries of constant likelihood ratios, source guessing for unrecognized items, and nonoptimal allocation
of attention can account for data from three canonical data sets without assuming any processes specifically devoted to recollection.
Observed and predicted ROCs for one of these data sets are given in the article, and ROCs for the other two may be downloaded

Williams syndrome (WS) is a genetic disorder associated with severe visuocognitive impairment. Individuals with WS also report difficulties with everyday wayfinding. To study the development of body-, environment-, and object-based spatial frames of reference in WS, we tested 45 children and adults with WS on a search task in which the participant and a spatial array are moved with respect to each other. Although individuals with WS showed a marked delay, like young controls they demonstrated independent, additive use of body- and environment-based frames of reference. Crucially, object-based (intrinsic) representations based on local landmarks within the array were only marginally used even by adults with WS, whereas in typical development these emerge at 5 years. Deficits in landmark use are consistent with wayfinding difficulties in WS, and may also contribute to problems with basic localization, since in typical development landmark-based representations supplement those based on the body and on self-motion. Difficulties with inhibition or mental rotation may be further components in the impaired ability to use the correct reference frame in WS. 相似文献

Successful memory is normally accompanied by explicit awareness of retrieval and confidence in the accuracy of the retrieval product. Prior findings suggest that these features of metamemory can be dissociated from retrieval accuracy in Amnestic Mild Cognitive Impairment (aMCI). However, the literature on this question contains variable and conflicting results, likely because of differences in experimental conditions. We sought to systematically evaluate memory awareness disruptions in aMCI using multiple measures and stimulus formats within the same individuals. Memory awareness was tested with global predictions and postdictions, judgments of learning, confidence level ratings, and modified feeling-of-knowing ratings in tasks of visuospatial and verbal memory. These tests were administered to 14 individuals with aMCI and 15 healthy, age-matched controls. Memory awareness accuracy was calculated as the correspondence between subjective judgments and memory performance.Individuals with aMCI demonstrated impaired global and trial-level retrospective task awareness for visuospatial and verbal stimuli. Additionally, modified feeling-of-knowing awareness was impaired selectively for verbal stimuli. Statistical effect sizes for global awareness impairments were comparable to impairments in several objective neuropsychological memory assessments.Memory awareness (metamemory) disruptions in aMCI were most evident for a subset of subjective judgment types and task input modalities. These findings advance understanding of the nature of memory impairments in aMCI and support the utility of incorporating memory awareness testing to better characterize memory integrity in older adults. 相似文献

Becoming a parent is a major developmental transition of adulthood. Individuals often have optimistic expectations about parenthood, yet this transition also presents a number of challenges. The authors investigated whether new parents have overly optimistic expectations about parenthood and, if they do, how this influences their adjustment to this role. The sample consisted of 71 first-time mothers who completed questionnaires during pregnancy and at 4 months postpartum. The study assessed women's expectations of caring for their infant and the influence parenthood would have on their well-being and their relationships with others. Most women's expectations were matched or exceeded by their parenting experiences. However, where experiences were negative relative to expectations, there was greater depression symptomatology and poorer relationship adjustment. 相似文献

Recent research has explored the dynamics of categorical thinking, with debate centering on the putative automaticity of this process. In a further investigation of this topic, the current inquiry assessed the influence of critical category‐cueing facial features on overt (i.e., category identification) and covert (i.e., category priming) measures of sex categorization. The results revealed that when a critical sex‐specifying facial cue (i.e., hairstyle) was present, priming effects emerged even under suboptimal processing conditions (i.e., facial blurring). When this cue was absent, however, priming no longer occurred. Interestingly, category identification was largely unimpeded by feature removal or facial blurring. Taken together, these results underscore the efficiency of categorical thinking and the importance of task objectives and feature‐based processing in person perception.

A version of Sternberg's (1966) short-term visual memory recognition paradigm with pictures of unfamiliar faces as stimuli was used in three experiments to assess the applicability of the distinctiveness-based SIMPLE model proposed by Brown, Neath, and Chater (2002). Initial simulations indicated that the amount of recency predicted increased as the parameter measuring the psychological distinctiveness of the stimulus material (c) increased and that the amount of primacy was dependent on the extent of proactive interference from previously presented stimuli. The data from Experiment 1, in which memory lists of four and five faces varying in visual similarity were used, confirmed the predicted extended recency effect. However, changes in visual similarity were not found to produce changes in c. In Experiments 2 and 3, the conditions that influence the magnitude of c were explored. These revealed that both the familiarity of the stimulus class before testing and changes in familiarity, due to perceptual learning, influenced distinctiveness, as indexed by the parameter c. Overall, the empirical data from all three experiments were well fit by SIMPLE. 相似文献
