The current study assumes that workers actively influence the characteristics of their work environment. Not only will one's work environment (job characteristics) affect personal characteristics, such as feelings of depression; depression in turn is expected to affect the characteristics of one's work environment as well. Using a sample of 593 young Dutch workers, a longitudinal model relating feelings of depression and job characteristics to each other was tested using structural equation modeling. The results largely supported our expectations. Depressive workers were less likely to experience a job transition than non-depressive workers. If depressive workers did experience a job transition, work outcomes were less positive than for nondepressive workers. Thus, it appears that the relation between job characteristics and depression can be construed as a reciprocal relation. Implications and limitations of the study are discussed. 相似文献

Avian brood parasites depend on other species, the hosts, to raise their offspring. During the breeding season, parasitic
cowbirds (Molothrus sp.) search for potential host nests to which they return for laying a few days after first locating them. Parasitic cowbirds
have a larger hippocampus/telencephalon volume than non-parasitic species; this volume is larger in the sex involved in nest
searching (females) and it is also larger in the breeding than in the non-breeding season. In nature, female shiny cowbirds Molothrus bonariensis search for nests without the male’s assistance. Here we test whether, in association with these neuroanatomical and behavioural
differences, shiny cowbirds display sexual differences in a memory task in the laboratory. We used a task consisting of finding
food whose location was indicated either by the appearance or the location of a covering disk. Females learnt to retrieve
food faster than males when food was associated with appearance cues, but we found no sexual differences when food was associated
with a specific location. Our results are consistent with the view that parasitism and its neuroanatomical correlates affect
performance in memory tasks, but the effects we found were not in the expected direction, emphasising that the nature of avian
hippocampal function and its sexual differences are not yet understood.

The mnemic neglect model predicts and accounts for selective memory for social feedback as a function of various feedback properties. At the heart of the model is the mnemic neglect effect (MNE), defined as inferior recall for self-threatening feedback compared to other kinds of feedback. The effect emerges both in mundane realism and minimal feedback settings. The effect is presumed to occur in the service of self-protection motivation. Mnemic neglect is pronounced when the feedback poses high levels of self-threat (i.e., can detect accurately one’s weakness), but is lost when self-threat is averted via a self-affirmation manipulation. Mnemic neglect is caused by self-threatening feedback being processed shallowly and in ways that separate it from stored (positive) self-knowledge. The emergence of mnemic neglect is qualified by situational moderators (extent to which one considers their self-conceptions modifiable, receives feedback from a close source, or is primed with improvement-related constructs) and individual differences moderators (anxiety, dysphoria, or defensive pessimism). Finally, the MNE is present in recall, but absent in recognition. Output interference cannot explain this disparity in results, but an inhibitory repression account (e.g., experiential avoidance) can: Repressors show enhanced mnemic neglect. The findings advance research on memory, motivation, and the self. 相似文献

There is a growing body of research suggesting that the shorter versions of the Test of Memory Malingering (TOMM) may provide an accurate assessment of effort in children. During neuropsychological evaluations, some circumstances result in only one completed trial of the TOMM or partial completion of a trial. Research suggests that a cut-score of 40 or 41 on Trial1 is highly predictive of passing the TOMM overall. In the current study, 194 school-age children with academic and/or behavioral problems were used to compare the accuracy of TOMM1 and TOMMe10 (errors on the first 10 items of TOMM1) in predicting passing/failing of TOMM2. For the children in this sample, a score of < 40 items correct (≥ 10 errors) on TOMM1 was highly accurate in predicting a passing performance on the TOMM2 (sensitivity = .80, specificity = .91) with a Negative Predictive Value = .98 at the malingering base rate of 7% (TOMM2 failure in our sample). A score of 2 errors (8 items correct) on the TOMMe10 was slightly less sensitive than that of the TOMM1 (specificity = .96, sensitivity = .53) but with a similar Negative Predictive Value (.96). Consistent with the research from adult populations, TOMM1 and TOMMe10 appear to be quite accurate in predicting performance on the standard administration of the TOMM and may be useful screeners. However, compared to that found in adult samples, slight differences in suggested cutoffs for TOMM1 and TOMMe10 may be warranted for children. 相似文献

In the memory conjunction paradigm, the number of times that constituents of conjunction lures were studied and the method of presentation were varied. In two experiments, participants were presented with eight parent items that could be recombined at test to form a conjunction lure. The constituents that were shared between the parent items and the conjunction lures were either presented in the same words (e.g., blackmail and jailbird presented four times each for the conjunction lure blackbird) or in different words (e.g., the targets footstool, footlocker, foothill, footbridge, baseball, softball, basketball, and golfball for the conjunction lure football). In both experiments, rates of false recognition were higher in the Different condition as opposed to the Same condition. These results provide evidence that participants in the Same condition were able to utilise a recall-to-reject strategy by remembering the repeatedly presented parent word. In the Different condition, participants were not able to utilise that strategy and instead relied on the familiarity of the repeatedly presented constituents which led to higher rates of false recognition. 相似文献

The police often appeal for eyewitnesses to events that were unlikely to have been emotive when observed. An eyewitness, however, may be in a negative mood whilst encoding or retrieving such events as mood can be influenced by a range of personal, social, and environmental factors. For example, bad weather can induce a negative mood. This experiment compared the impact of negative and neutral moods during encoding and/or retrieval upon eyewitness recall of a non-emotive event. A negative mood during encoding had no impact upon the number of correct details recalled (provided participants were in a neutral mood at retrieval) but a negative mood during retrieval impaired the number of correct details recalled (provided participants were in a neutral mood at encoding). A negative mood at both time points enhanced the number of correct details recalled, demonstrating a mood-dependent memory enhancement. The forensic implications of these findings are discussed. 相似文献

The present study examines age differences in the memory benefits from group-referncing. While prior work establishes that the memory performance of younger and older adults similarly benefits from relating information to the self, this study assessed whether those benefits extend to referencing a meaningful group membership. Young and older adult participants encoded trait words by judging whether each word describes themselves, describes their group membership (selected for each age group), or is familiar. After a retention interval, participants completed a surprise recognition memory test. The results indicate that group-referencing increased recognition memory performance compared to the familiarity judgements for both young and older groups. However, the group-reference benefit is limited, emerging as smaller than the benefit from self-referencing. These results challenge previous findings of equivalent benefits for group-referencing and self-referencing, suggesting that such effects may not prevail under all conditions, including for older adults. The findings also highlight the need to examine the mechanisms of group-referencing that can lead to variability in the group-reference effect. 相似文献

The production effect (PE) documents the advantage in memory performance for words that are read aloud during study, rather than words that are read silently. Until now, the PE was examined in the visual modality, as the participants read the study words. In the present study, we extended the PE phenomenon and used the auditory modality at study. This novel methodology provides a critical test of the distinctiveness account. Accordingly, the participants heard the study words and learned them by vocal production (saying aloud) or by writing, followed by a free recall test. The use of the auditory modality yielded a memory advantage for words that were written during study over words that were vocally produced. We explain this result in light of the encoding distinctiveness account, suggesting that the PE is determined by the number of different encoding processes involved in learning, emphasising the essential role of active production. 相似文献

Students' self-reported study skills and beliefs are often inconsistent with empirically supported (ES) study strategies. However, little is known regarding instructors' beliefs about study skills and if such beliefs differ from those of students. In the current study, we surveyed college students' and instructors' knowledge of study strategies and had both groups evaluate the efficacy of learning strategies described in six learning scenarios. Results from the survey indicated that students frequently reported engaging in methods of studying that were not optimal for learning. Instructors' responses to the survey indicated that they endorsed a number of effective study skills but also held several beliefs inconsistent with research in learning and memory (e.g., learning styles). Further, results from the learning scenarios measure indicated that instructors were moderately more likely than students to endorse ES learning strategies. Collectively, these data suggest that instructors exhibited better knowledge of effective study skills than students, although the difference was small. We discuss several notable findings and argue for the improvement of both students' and instructors' study skill knowledge. 相似文献

In the widely used Corsi Block Test and Wechsler Spatial Span Tests, participants must reproduce sequences of blocks in the order touched by the examiner until two trials are missed at the same sequence length. The examiner records either the maximum number of blocks correctly reported or the total number of correct lists. Here, we describe a computerized spatial span test (C-SST) that uses psychophysical procedures to quantify visuospatial mean span (MnS) with sub-digit precision. Results from 187 participants ranging in age from 18 to 82 years showed that accuracy declined gradually with list length around the MnS (by ~30% per item). Simulation studies revealed high variance and biases in CBT and Wechsler measures, and demonstrated that the C-SST provided the most accurate estimate of true span (i.e., the sequence length producing 50% correct). MnS declined more rapidly with age than mean digit span (MnDS) measured in the same participants. Response times correlated with both MnS and MnDS scores. Error analysis showed that omission and transposition errors predominated, with weaker primacy and recency effects in spatial span than digit span testing. The C-SST improves the precision of spatial span testing and reveals significant differences between visuospatial and verbal working memory. 相似文献
