Three studies examined whether younger and older adults better recall information associated with their own than information related to another age group. All studies compared young and older adults with respect to incidental memory for previously presented stimuli (Studies 1 and 2: everyday objects; Study 3: vacation advertisements) that had been randomly paired with an age-related cue (e.g., photo of a young or an old person; the word "young" or "old"). All three studies found the expected interaction of participants' age and age-associated information. Studies 1 and 2 showed that the memory bias for information arbitrarily associated with one's own as compared to another age group was significant for older adults only. However, when age-relevance was introduced in a context of equal importance to younger and older adults (information about vacations paired either with pictures of young or older adults), the memory bias for one's own age group was clearly present for both younger and older adults (Study 3). 相似文献

The psychometric properties of a revised version of the Male Body Attitudes Scale (Tylka, Bergeron, & Schwartz, 2005) were investigated using two independent online samples of Irish men (ns=241 and 253, respectively). Exploratory factor analyses suggested that a 15-item, 3-factor solution representing men's attitudes toward their body fat, muscularity, and height best described the data. The internal consistency and construct validity of scores on the Revised Male Body Attitudes Scale suggest that this measure holds promise as an indicant of men's attitudes toward their physical appearance. Limitations and strengths associated with the current research are discussed and directions for future research are outlined. 相似文献

Two experiments studied perceptual comparisons with cues that vary in one of four ways (picture, sound, spoken word, or printed word) and with targets that are either pictures or environmental sounds. The basic question probed whether modality or differences in format were factors that would influence picture and sound perception. Also of interest were cue effect differences when targets are presented on either the right or left side. Students responded to a same-different reaction time task that entailed matching cue-target pairs to determine whether the successive stimulus events represented features drawn from the same basic item. Cue type influenced reaction times to pictures and environmental sounds, but the effects were qualified by response type and with picture targets by presentation side. These results provide some additional evidence of processing asymmetry when pictures are directed to either the right or left hemisphere, as well as for some asymmetries in cross-modality cuing. Implications of these findings for theories of multisensory processing and models of object recognition are discussed. 相似文献

A handful of prior adoption studies have confirmed that the cross-sectional relationship between child conduct problems and parent-child conflict at least partially originates in the shared environment. However, as the direction of causation between parenting and delinquency remains unclear, this relationship could be better explained by the adolescent's propensity to elicit conflictive parenting, a phenomenon referred to as an evocative gene-environment correlation. In the current study, the authors thus examined the prospective relationship between conduct problems and parent-child conflict in a sample of adoptive families. Participants included 672 adolescents in 405 adoptive families assessed at 2 time points roughly 4 years apart. Results indicated that parent-child conflict predicts the development of conduct problems, whereas conduct problems do not predict increases in parent-child conflict. Such findings suggest that evocative gene-environment correlations are highly unlikely to be an explanation of prior shared environmental effects during adolescence. Moreover, because the adolescents in this study do not share genes with their adoptive parents, the association between conduct problems and parent-child conflict is indicative of shared environmental mediation in particular. Implications of the findings are discussed. 相似文献

This study examined the main and interactive relations of stressors and coping related to severe acute respiratory syndrome (SARS) with Chinese college students' psychological adjustment (psychological symptoms, perceived general health, and life satisfaction) during the 2003 Beijing SARS epidemic. All the constructs were assessed by self-report in an anonymous survey during the final period of the outbreak. Results showed that the relations of stressors and coping to psychological adjustment varied by domain of adjustment. Regression analyses suggested that the number of stressors and use of avoidant coping strategies positively predicted psychological symptoms. Active coping positively predicted life satisfaction when controlling for stressors. Moreover, all types of coping served as a buffer against the negative impact of stressors on perceived general health. These findings hold implications for university counseling services during times of acute, large-scale stressors. In particular, effective screening procedures should be developed to identify students who experience a large number of stressors and thus are at high risk for developing mental health problems. Intervention efforts that target coping should be adapted to take account of the uncontrollability of stressors and clients' cultural preferences for certain coping strategies. A multidimensional battery of psychological adjustment should be used to monitor clients' psychological adjustment to stressors and evaluate the efficacy of intervention. 相似文献

BackgroundThe Neonatal Behavioral Assessment Scale (NBAS, Brazelton &; Nugent, 1995) is an instrument conceived to observe the neonatal neurobehavior. Data analysis is usually performed by organizing items into groups. The most widely used data reduction for the NBAS was developed by Lester, Als, and Brazelton (1982).ObjectiveExamine the psychometric properties of the NBAS items in a sample of 213 Portuguese infants.MethodThe NBAS was performed in the first week of infant life (3 days ± 2) and in the seventh week of life (52 days ± 5).ResultsPrincipal component analyses yielded a solution of four components explaining 55.13% of total variance. Construct validity was supported by better neurobehavioral performance of 7-week-old infants compared with 1-week-old infants.ConclusionChanges in the NBAS structure for the Portuguese sample are suggested compared to Lester factors in order to reach better internal consistency of the scale. 相似文献

The present study examined the relationship between hand preference degree and direction, functional language lateralization in Broca’s and Wernicke’s areas, and structural measures of the arcuate fasciculus. Results revealed an effect of degree of hand preference on arcuate fasciculus structure, such that consistently-handed individuals, regardless of the direction of hand preference, demonstrated the most asymmetric arcuate fasciculus, with larger left versus right arcuate, as measured by DTI. Functional language lateralization in Wernicke’s area, measured via fMRI, was related to arcuate fasciculus volume in consistent-left-handers only, and only in people who were not right hemisphere lateralized for language; given the small sample size for this finding, future investigation is warranted. Results suggest handedness degree may be an important variable to investigate in the context of neuroanatomical asymmetries. 相似文献

The psychometric soundness of the Muscle Appearance Satisfaction Scale (MASS; Mayville, Williamson, White, Netemeyer, & Drab, 2002), a measure of muscle dysmorphia symptoms, was investigated using two independent online samples of Irish and British men (ns = 307 and 306, respectively). Exploratory and confirmatory factor analyses showed that, compared to the original 5-component solution for the 19-item MASS, a 6-item unidimensional version offered better fit to the data. Findings further upheld the internal consistency reliability, construct validity (e.g., via its associations with internalization of the muscular ideal and physical appearance comparisons), and discriminant validity (e.g., via its nonsignificant relationship with social desirability) of the MASS's scores. The limitations associated with the current research are discussed and directions for future research are articulated. 相似文献

A psychological refractory period (PRP) approach and the locus of slack logic were applied to examine the novel question of whether spatial translation processes can begin before the central bottleneck when effector or noneffector stimuli are processed from an egocentric (viewer-centered) perspective. In single tasks, trials requiring spatial translations were considerably slower than trials without translations (Experiment 1). Dual tasks consisted of tone discriminations (Task 1) and spatial translations (Task 2) using PRP methods with different manipulations on perceptual and response demands. When a viewer-centered perspective was used, the effect of spatial translation was reduced at short compared with long stimulus onset asynchronies (SOAs) when the potential for code overlap between tasks was removed (Experiments 2, 3, and 4); this finding supports the view that translation processes can begin before the central bottleneck. When an allocentric (non-viewer-centered) perspective was used (Experiment 5), the slowing associated with spatial translation was additive with SOA, suggesting that the processes of spatial translation cannot begin before the bottleneck. These findings highlight the importance of viewer perspective on central bottleneck requirements. Findings are further discussed in relation to the dorsal-ventral model of action and perception. 相似文献

The nature of phoneme representation in spoken word recognition 总被引:1,自引:0,他引:1

Four experiments used the psychological refractory period logic to examine whether integration of multiple sources of phonemic information has a decisional locus. All experiments made use of a dual-task paradigm in which participants made forced-choice color categorization (Task 1) and phoneme categorization (Task 2) decisions at varying stimulus onset asynchronies. In Experiment 1, Task 2 difficulty was manipulated using words containing matching or mismatching coarticulatory cues to the final consonant. The results showed that difficulty and onset asynchrony combined in an underadditive way, suggesting that the phonemic mismatch was resolved prior to a central decisional bottleneck. Similar results were found in Experiment 2 using nonwords. In Experiment 3, the manipulation of task difficulty involved lexical status, which once again revealed an underadditive pattern of response times. Finally, Experiment 4 compared this prebottleneck variable with a decisional variable: response key bias. The latter showed an additive pattern of responses. The experiments show that resolution of phonemic ambiguity can take advantage of cognitive slack time at short asynchronies, indicating that phonemic integration takes place at a relatively early stage of spoken word recognition. 相似文献
