This article is concerned with how information about time and position in a sequence is represented in short-term memory and
expressed in the dynamics of serial recall. Temporal-distinctiveness theories of memory predict that isolating a list item
in time will improve recall accuracy for that item. Although the majority of research in short-term memory has failed to demonstrate
a temporal isolation effect (TIE), there are occasions on which a TIE is observed. The disparity in results has been explained
by assuming that participants can adaptively weight temporal and nontemporal information at retrieval, with differences between
experiments promoting or discouraging reliance on time as a source of episodic information. A particular focus of the present
study is the finding that the TIE is substantially observed in standard serial recall only when participants are instructed
to group the list into minisequences. The findings of two experiments using instructed grouping replicated this effect but
showed that it is attributable to a longer gap at the group boundary enhancing the positive effect of grouping on recall accuracy.
These results show that the hierarchical representations usually associated with temporal grouping are also elicited by instructed
grouping but that an additional and nonspecific benefit to recall obtains from lengthening the pause between groups. An additional
role for time is identified in the timing of responses: The dynamics of input sequences tend to be mirrored in output sequences
for ungrouped lists, whereas the primacy pattern in grouped lists is for a longer duration to speed access to the following
group when that duration occurs at an instructed group boundary. 相似文献

Listeners rapidly adapt to many forms of degraded speech. What level of information drives this adaptation, however, remains unresolved. The current study exposed listeners to sinewave-vocoded speech in one of three languages, which manipulated the type of information shared between the training languages (German, Mandarin, or English) and the testing language (English) in an audio-visual (AV) or an audio plus still frames modality (A + Stills). Three control groups were included to assess procedural learning effects. After training, listeners' perception of novel sinewave-vocoded English sentences was tested. Listeners exposed to German-AV materials performed equivalently to listeners exposed to English AV or A + Stills materials and significantly better than two control groups. The Mandarin groups and German-A + Stills group showed an intermediate level of performance. These results suggest that full lexical access is not absolutely necessary for adaptation to degraded speech, but providing AV-training in a language that is similar phonetically to the testing language can facilitate adaptation. 相似文献

The aim of the present study was to translate into Spanish and to describe the psychometric properties of the Stress Manifestations Scale of the Student Stress Inventory (SSI-SM), developed by Fimian, Fastenau, Tashner and Cross to identify the main manifestations of stress in adolescents. The scale was applied to a sample of 1,002 pupils from years one and two of Secondary Education. The paper reports the factor structure, an item analysis, the internal consistency, differences by sex and academic year, external evidence of validity, and norms for scoring the scale. The results reveal a factor structure based on three first-order factors (emotional manifestations, physiological manifestations and behavioural manifestations) and one second-order factor (indicative of stress manifestations). In terms of external validity, there was a positive association with measures of perceived stress, aggressiveness, internalized/externalized symptoms, and a negative association with life satisfaction. The results show that the scale is an adequate tool for evaluating stress manifestations in adolescents. 相似文献

Several ethological reports have indicated that cooperative behaviors play an adaptive role. However, research has focused on competition in men, and there have been few studies on cooperation. This study aims to analyze the cortisol and psychological responses in women to a cooperative situation compared with a competitive situation in a laboratory context. The sample was distributed into four groups depending on the task and the outcome obtained: Positive cooperation, negative cooperation, competition with victory, and competition with defeat. Our results show that, in comparison with competition, cooperation produces different effects in cortisol, but not in psychological states. Nevertheless, these effects occur only when the task outcome and its appraisal are considered. Only the participants who cooperated and obtained a positive outcome and those who competed and lost showed significant decrements of cortisol. Internal attribution was higher in groups with more stable cortisol levels, suggesting a possible modulator effect of controllability in the way the situation was experienced. These results could be generalized to situations in which negotiation, mediation, and cooperative strategies are relevant for making decisions and/or solving problems. 相似文献

Emotional factors have been found to be an important influence on memory. The current study investigated the influence of emotional salience and age on a laboratory measure of prospective memory (PM); Virtual Week. Thirty young and 30 old adults completed Virtual Week, in which the emotional salience of the tasks at encoding was manipulated to be positive, negative or neutral in content. For event-based, but not time-based tasks, positivity enhancement in both age groups was seen, with a greater number of positive PM tasks being performed relative to neutral tasks. There was no negativity enhancement effect. Older adults showed generally poorer levels of PM, but they also demonstrated greater beneficial effects of positive valence compared to young. These effects of emotion on PM accuracy do not appear to reflect the retrospective component of the task as a different pattern of emotion effects was seen on the recall of PM content. Results indicate that older adults' difficulties in prospective remembering can be reduced where the tasks to be remembered are positive. 相似文献

The phrase “wild analysis” is evaluated with a view to understanding something about the conditions and constraints on psychoanalytic theory and practice. Muriel Dimen’s paper is also read as a prologue for new, less restrictive stories about the nature of psychoanalysis. 相似文献

Appearance is one way in which lesbian and bisexual identities and affiliation to lesbian, gay, bisexual (LGB) subculture can be demonstrated. ‘Butch’ and ‘androgynous’ styles have been used by lesbian women to communicate a non‐heterosexual identity. However, some LGB appearance researchers have argued that there has been a mainstreaming and diversification of lesbian style in the last couple of decades, which has resulted in less distinction between lesbian and straight looks. This research draws on the Social Identity approach to explore contemporary style in lesbian and bisexual communities. Fifteen lesbian and bisexual women took part in semi‐structured interviews which were analysed using thematic analysis. Although some participants reported a diversification of lesbian style, most used the term ‘butch’ to describe lesbian style, and a ‘boyish’ look was viewed as the most common contemporary lesbian style. By contrast, most participants could not identify distinct bisexual appearance norms. The data provide evidence of conflicting desires (and expectations) to visibly project social identity by conforming to specific lesbian styles, and to be an authentic, unique individual by resisting these subcultural styles.

Advances in whole genome and whole exome sequencing (WGS/WES) technologies have led to increased availability in clinical settings. Currently, there are few guidelines relating to the process and content of informed consent for WGS/WES, nor to which results should be returned to families. To address this gap, we conducted focus groups to assess the views of professionals, parents, and adolescents for the future implementation of WES. The discussions assessed understanding of the risks and benefits of WES, preferences for the informed consent discussion, process for return of results, and the decision-making role of the pediatric patient. Professional focus group participants included bioethicists, physicians, laboratory directors, and genetic counselors. Parent focus groups included individuals with children who could be offered sequencing due to a potential genetic cause of the child’s condition. On-line discussion groups were conducted with adolescents aged 13–17 who had a possible genetic disorder. We identified discrepancies between professionals and patient groups regarding the process and content of informed consent, preference for return of results, and the role of the child in decision-making. Professional groups were concerned with the uncertainty regarding professional obligations, changing interpretation in genomic medicine, and practical concerns of returning results over time. Parent and adolescent groups focused on patient choice and personal utility of sequencing results. Each group expressed different views on the role of the child in decision-making and return of results. These discrepancies represent potential barriers to informed consent and a challenge for genetic counselors regarding the involvement of pediatric patients in decision-making and return of results discussions. 相似文献
