Three experiments examined factors responsible for improvement in visual search. In Experiment I three groups of subjects were each trained for 3000 trials to search for a particular set of target letters among a particular set of background letters. After intervals of 2, 4, or 6 weeks without further practice they were re-tested, either with the same displays or on new displays which they searched for the same target items among new background items. Negative transfer suggested that memory for specific cue-systems distinguishing target from background letters is retained for as long as 4 weeks.
Experiment II examined performance of three very highly practised subjects. After 25 days practice, variations in the size of the target set no longer affected search time. This could not be explained by learning of specific cue systems, since after this amount of practice subjects showed perfect transfer to displays which they searched for the same target items among new background items. Experiment III suggested that practised subjects achieve this high level of competence by learning to make two independent successive decisions, first to locate any member of the target set on the display and next to identify which particular member of the target set has been located. 相似文献

The Eating Behavior Inventory (EBI) is a self-report instrument for assessing behaviors that have been theoretically implicated in weight loss, e.g., self-monitoring of food intake and of weight, refusing offers of food, eating at only one place, shopping from a list, eating in response to emotions. Thirty items were constructed in the form of first-person statements, e.g., I eat in the middle of the night. Each item was to be rated with a 5-point scale according to how often it was true for the respondent. Items were scored such that higher scores always reflected more appropriate (theoretically facilitative of weight control) eating patterns. Validity of individual items and total score was assessed in four studies. Twenty-six of the original items appeared valid and were retained. The resulting total score demonstrated validity in these studies and in two cross-validational comparisons. Internal consistency as measured by split-half reliability and correlations of item scores with total score was acceptable. One month test-retest reliability of item and total scores was satisfactory. Clinical and research applications of the EBI are discussed.An early version of this article was presented at the Taos International Conference on Treatment of Addictive Behaviors, Taos, New Mexico, February 1979. 相似文献

The ability to detect small differences in the positions of two lines (vernier acuity) showed some improvement with practice in all eight subjects, even for subjects given no error feedback. The average decline in threshold with training (2,000–2,500 responses) was about 40%. We used three target orientations: vertical, horizontal, and right oblique. Orientational differences remained stable in only one subject. In five subjects, orientational differences present at the beginning of training diminished or disappeared with increased experience; in two, they increased. 相似文献

This study examined the relationship between sex-role and nontraditional major choice. The sample included 693 male and female students enrolled in traditional and nontraditional majors. In addition to exploring this relationship the study had a methodological intent: Could scales derived from previous factor analyses of the Bem Sex-Role Inventory delineate this relationship as readily as the traditional Bem scoring method. Results indicate significant distributional patterns in sex-role and choice of major, which vary by sex. Men tend to choose male-dominated majors, regardless of sex-role. Patterns for females are more complex. The factored scales used in cross-validated discriminate analysis procedures did demonstrate some power to discriminate students in the two majors, suggesting certain implications for sex-role transcendence in vocational settings. 相似文献

Much of the research on psychopathy has treated it as a unitary construct operationalized by total scores on one (or more) measures. More recent studies on the Psychopathic Personality Inventory (PPI) suggest the existence of two distinct facets of psychopathy with unique external correlates. Here, the authors report reanalyses of two offender data sets that included scores on the PPI along with various theoretically relevant criterion variables. Consistent with hypotheses, the two PPI factors showed convergent and discriminant relations with criterion measures, many of which would otherwise have been obscured when relying on PPI total scores. These results highlight the importance of examining facets of psychopathy as well as total scores. 相似文献

The authors examined the effect of sound-to-spelling regularity on written spelling latencies and writing durations in a dictation task in which participants had to write each target word 3 times in succession. The authors found that irregular words (i.e., those containing low-probability phoneme-to-grapheme mappings) were slower both to initially produce and to execute in writing than were regular words. The regularity effect was found both when participants could and could not see their writing (Experiments 1 and 2) and was larger for low- than for high-frequency words (Experiment 3). These results suggest that central processing of the conflict generated by lexically specific and assembled spelling information for irregular words is not entirely resolved when the more peripheral processes controlling handwriting begin. 相似文献

Concern has been raised about the lack of participant compliance in diary studies that use paper-and-pencil as opposed to electronic formats. Three studies explored the magnitude of compliance problems and their effects on data quality. Study 1 used random signals to elicit diary reports and found close matches to self-reported completion times, matches that could not plausibly have been fabricated. Studies 2 and 3 examined the psychometric and statistical equivalence of data obtained with paper versus electronic formats. With minor exceptions, both methods yielded data that were equivalent psychometrically and in patterns of findings. These results serve to at least partially mollify concern about the validity of paper diary methods. 相似文献

Flashbulb memories (FMs) are vivid, long-lasting memories for the source of surprising, arousing news. Laboratory studies have consistently found that older adults, especially those with below-average frontal lobe (FL) function, are impaired in source memory relative to young. We tested memory for the source of news concerning the September 11th terrorist attacks in older adults with high or low frontal lobe function and in young people. We found no age differences in source memory a year after the event and no differences related to FL function. Flashbulb memories may be different from usual cases of source memory because of their emotional content, personal importance, or social relevance. 相似文献

The present study examined the role of mothers’ communication with children about interparental disputes in associations between interparental conflict and child psychological maladjustment in a sample of 227 children and their parents followed over a one-year span. Most of the time (i.e., 79.8%) mothers reported that they would communicate with their children following interparental disputes, with the vast majority of those communications containing relatively constructive depictions of interparental conflict. Post-conflict communications were not associated with children’s adjustment above and beyond the impact of interparental conflict. However, maternal communications underscoring family cohesion and warmth, emphasizing remorse for engaging in the interparental disagreement, and denying the occurrence of the dispute each moderated associations between interparental conflict and child externalizing symptoms in distinct, complex ways. The findings in general suggest that not all positive communications have the beneficial impact on children that parents may have intended. 相似文献
