In two experiments, the effect of perceptual distinctiveness of cues on prospective memory performance was examined. Young and older adults completed a visual search task with embedded prospective memory instructions. On each trial, participants were asked to indicate the position of a target letter in a letter string, unless either of two letters previously identified as prospective memory cues was presented. Each prospective cue was associated with a specific response. Perceptual distinctiveness was manipulated by spatially displacing a single letter. The prospective component (successful detection of the cue) and the retrospective memory component (recalling the correct response when a cue is detected) were measured separately. Perceptual displacement of cues modulated performance of the prospective component but not the retrospective component. Young adults successfully detected a larger proportion of cues (prospective component) than older adults. However, there were minimal effects of age and no effect of cue displacement on participants' ability to recall the intention once they detected a cue (retrospective component performance). Results are discussed within the context of current theoretical models of prospective memory. 相似文献

Distinguishing the desire to learn from the desire to perform: The social value of achievement goals
We sought to distinguish mastery goals (i.e., desire to learn) from performance goals (i.e., desire to achieve more positive evaluations than others) in the light of social judgment research. In a pilot study, we made a conceptual distinction between three types of traits (agency, competence, and effort) that are often undifferentiated. We then tested the relevance of this distinction for understanding how people pursuing either mastery or performance goals are judged. On self-perception, results revealed that effort was predicted by the adoption of mastery goals and agency by performance goals (Study 1). On judgments, results showed that (a) the target pursuing mastery goals was perceived as oriented toward effort, and (b) the target pursuing performance goals was oriented toward agency (Study 2). Finally, these links were shown again by participants who inferred a target’s goals from his traits (Study 3). Results are discussed in terms of the social value of achievement goals at school. 相似文献

Approaches to love were explored to determine links to psychological experiences after romantic betrayal. Results indicated that the mania (obsessive) love style predicted post-betrayal trauma reactions, depression, and psychosomatic symptoms, whereas other styles were unrelated to these post-betrayal reactions. Weaker effects also were observed in which the mania style was related to post-betrayal anxiety and embarrassment, as well as low levels of psychological resolution for the betrayal across time among those who were no longer involved with their betrayers. 相似文献

This paper is an exploration into the question, “What does considering gestational life add to analytic theory and practice?” It attempts to situate prenatal experience in the psychoanalytic dialogue, to explore its place in subsequent mental life, to discuss how this may be useful in clinical process, and to reconceptualize some theory in light of a gestational perspective. Neuro-psychoanalytic theory is utilized with an emphasis on nonconscious mental process which takes the form of implicit memory, providing people with a sense of continuity and well-being or stress. Intra-uterine experience can include pain and suffering. Fetal stress is an integral part of prenatal development and its metaphorical use in clinical practice. Three concepts—gestational being/becoming, geatational holding, and objectless intersubjectivity—are offered as ideas to introduce order and conceptual clarity into the ineffable mysteries of in utero process. A gestational perspective is used to describe how the analyst intuitively tracks the patient’s sense of well-being/stress. 相似文献

The aims of this study were to document movement of genetic counselors (GCs) out of clinical positions and identify factors that might help employers attract and retain clinical GCs. A confidential on-line survey of GCs ever licensed in the state of Indiana was conducted. Of the 46 respondents, most provide direct patient care (69.6 %), have worked in their current position for 5 years or less (72.1 %), and are experienced genetic counselors, having graduated between 6 and 15 years ago (43.5 %). One-third (32.6 %) reported thinking about leaving their current position at least monthly. GCs were more likely to think about leaving their current position when they provided direct patient care (p = 0.04) and worked in a hospital/clinic setting (p = 0.01). Among the 18 respondents that changed jobs in the past two years, 55.6 % currently work in a laboratory/industry setting and 44.4 % provide direct patient care, compared to 8 % of those in a stable position (N = 25) who work in a laboratory/industry setting (p < 0.01) and 88 % who provide direct patient care (p < 0.01). Genetic counselors who have changed jobs within the past 2 years were more satisfied with the possibility for advancement (p = 0.01), the recognition for work they do (p = 0.03) and feeling value from the organization (p = 0.04) in their current positions than those who have not changed jobs. Salary and flexibility were most often reported as reasons for changing jobs. This is the first documentation of the movement of GCs out of clinical roles into industry positions. This changing landscape may impact the access to clinical services and the training of genetic counseling students. This data will provide employers with data to help attract and retain GCs in clinical roles. 相似文献

High levels of locus coeruleus (LC) tonic activity are associated with distraction and poor performance within a task. Adaptive gain theory (AGT; Aston-Jones & Cohen, 2005) suggests that this may reflect an adaptive function of the LC, encouraging search for more remunerative opportunities in times of low utility. Here, we examine whether stimulating LC tonic activity using designer receptors (DREADDs) promotes searching for better opportunities in a patch-foraging task as the value of a patch diminishes. The task required rats to decide repeatedly whether to exploit an immediate but depleting reward within a patch or to incur the cost of a time delay to travel to a new, fuller patch. Similar to behavior associated with high LC tonic activity in other tasks, we found that stimulating LC tonic activity impaired task performance, resulting in reduced task participation and increased response times and omission rates. However, this was accompanied by a more specific, predicted effect: a significant tendency to leave patches earlier, which was best explained by an increase in decision noise rather than a systematic bias to leave earlier (i.e., at higher values). This effect is consistent with the hypothesis that high LC tonic activity favors disengagement from current behavior, and the pursuit of alternatives, by augmenting processing noise. These results provide direct causal evidence for the relationship between LC tonic activity and flexible task switching proposed by AGT. 相似文献
