This article describes the development and validation of a biographical data (biodata) measure and situational judgment inventory (SJI) as useful predictors of broadly defined college student performance outcomes. These measures provided incremental validity when considered in combination with standardized college-entrance tests (i.e., SAT/ACT) and a measure of Big Five personality constructs. Racial subgroup mean differences were much smaller on the biodata and SJI measures than on the standardized tests and college grade point average. Female students tended to outperform male students on most predictors and outcomes with the exception of the SAT/ACT. The biodata and SJI measures show promise for student development contexts and for selecting students on a wide range of outcomes with reduced adverse impact. 相似文献

The purpose of this study is to see if there are age differences in the relationship between chronic financial strain, emotional support, and life satisfaction among people aged 65 and older. Data from a nationwide survey of older people (N = 1,518) indicate that emotional support tends to reduce the noxious effects of economic problems on life satisfaction for the sample as a whole. However, the findings further reveal that the potential benefits of emotional support arise primarily among the oldest-old. In contrast, emotional support does not offset the negative effects of financial strain on life satisfaction among the young-old. 相似文献

Infant crying signals distress to potential caretakers who can alleviate the aversive conditions that gave rise to the cry. The cry signal results from coordination among several brain regions that control respiration and vocal cord vibration from which the cry sounds are produced. Previous work has shown a relationship between acoustic characteristics of the cry and diagnoses related to neurological damage, SIDS, prematurity, medical conditions, and substance exposure during pregnancy. Thus, assessment of infant cry provides a window into the neurological and medical status of the infant. Assessment of infant cry is brief and noninvasive and requires recording equipment and a standardized stimulus to elicit a pain cry. The typical protocol involves 30 seconds of crying from a single application of the stimulus. The recorded cry is submitted to an automated computer analysis system that digitizes the cry and either presents a digital spectrogram of the cry or calculates measures of cry characteristics. The most common interpretation of cry measures is based on deviations from typical cry characteristics. Another approach evaluates the pattern across cry characteristics suggesting arousal or under-arousal or difficult temperament. Infants with abnormal cries should be referred for a full neurological evaluation. The second function of crying--to elicit caretaking--involves parent perception of the infant's needs. Typically, parents are sensitive to deviations in cry characteristics, but their perception can be altered by factors in themselves (e.g., depression) or in the context (e.g., culture). The potential for cry assessment is largely untapped. Infant crying and parental response is the first language of the new dyadic relationship. Deviations in the signal and/or misunderstanding the message can compromise infant care, parental effectiveness, and undermine the budding relationship. (c) 2005 Wiley-Liss, Inc.

This article provides evidence for implicit change detection and for the contribution of multiple memory sources to online representations. Multiple eye-movement measures distinguished original from changed scenes, even when college students had no conscious awareness for the change. Patients with amnesia showed a systematic deficit on 1 class of eye-movement measures of change detection, even though conscious awareness was not required for the effect to be observed. The authors' findings suggest that online representations of scenes are (a) built up across viewings, (b) composed of activated information from both long-term and working memory, and (c) directly compared with currently processed information regarding the external world. Subsequent online processing is influenced by these representations even when the results of the comparison are not accessible for verbal report. 相似文献

A descriptive epidemiology of lifetime trauma and the physical health status of older adults 总被引:1,自引:0,他引:1
Three issues are evaluated in this study. The 1st involves examining the relationship between exposure to trauma over the life course and physical health status in old age. The 2nd has to do with seeing whether the relationship between trauma and health varies across 3 cohorts of older adults: the young-old (ages 65-74), the old-old (ages 75-84), and the oldest old (age 85 and over). The 3rd issue involves seeing whether the age at which a trauma was encountered is related to health in late life. Data from a nationwide survey of older people (N=1,518) reveal that trauma is associated with worse health. Moreover, the young-old appear to be at greatest risk. Finally, data suggest that trauma arising between the ages of 18 and 30 years, as well as ages 31 to 64 years, has the strongest relationship with current health. 相似文献

Through surveying of children in 10 nations with parent, teacher, and Youth Self-Report (YSR) forms of the Child Behavior Checklist (CBCL), cross-informant syndromes (CISs) were derived and cross-validated by sample-dependent methodology. Generalizing CBCL syndromes and norms to nations excluded from its normative sample is problematic. This study used confirmatory factor analyses (CFAs) to test factor model fit for CISs on the YSR responses of 625 Jamaican children ages 11 to 18 years. Item response theory (IRT), a sample-independent methodology, was used to estimate the psychometric properties of individual items on each dimension. CFAs indicated poor to moderate model-to-data fit. Across all syndromes, IRT analyses revealed that more than 3/4 of the cross-informant items yielded little information. Eliminating such items could be cost effective in terms of administration time yet improve the measures discrimination across syndrome severity levels. 相似文献

Some research designs require subjects to make ratings of their own internal cognitive or affective states or the behavior of other subjects. An ideal device for this purpose should allow for electronic data storage and be easy to use for research subjects. The communication box (Markman & Poltrock, 1982) has been popular for this purpose but consists of dated technology. Other data-logging devices are too complicated for subjects’ use. This paper describes an electronic data logger which uses readily available hardware. A dual-tone multiple-frequency (DTMF) telephone keypad encoder is used to generate unique tones that are stored on the audio track of a videotape or on an audio tape. A DTMF receiver decoder IC is used to decode the audio signals. The decoded signals can be read on a light-emitting diode display or entered directly into a personal computer file via an RS-232 serial interface. 相似文献

Male and female black undergraduates enrolled in Introductory Psychology and Human Development courses at a predominantly black university responded to five stories about married black physicians whose total income was greatest, respectively, when the husband cared for the children (Story 1), the wife cared for the children (Story 2), either spouse cared for them (Story 3), the wife earned more than the husband (Story 4), or the husband earned more than the wife (Story 5). In contrast to the results of a study completed at a predominantly white university, black females favored maternal child care even when, as a result, the family income was reduced and had significantly less of a preference for higher relative salary for the wife than did females in the study at a predominantly white university; although black males preferred maternal child care in Story 2 and Story 3, the preference was significantly less than that of males in the study at a predominantly white university. The results were discussed in terms of their relevance to collaborating career patterns among middle-class black families. 相似文献

Individual differences and segment interactions in throwing 总被引:1,自引:0,他引:1
Arm segment velocities of 12 athletes throwing three differently weighted balls were analyzed by three-mode principal component analysis. Individual differences were characterized in terms of the combined influences of the phases of the throwing motion and the arm segment velocity relationships established in those phases. Using three individual differences components, three velocity measures components and four time phase components, 75% of the variance was described. The arm segment velocity relationships were described by two main components identified as directional velocity and proximal versus distal velocity. The time periods components distinguished between relationships among the arm segment velocities that occur in the windup versus those of the release phase. Three individual differences components are identified and appeared to be related to a general throwing style, the influence of skill level on technique, and the differential effect of the varying ball weights, respectively. Each athlete's throws are weighted combinations of these three components. The timing of segment involvement is investigated and the results indicate sequential patterns from proximal to distal as the throw unfolds. However, the results also suggest that different principles may apply to different throwers and that the summation of speed principle should not be applied universally to explain segment motion and interaction. 相似文献

Decreased variability of both response outcome and movement kinematics is generally thought to be a characteristic of skilled performance. This note reports an apparently paradoxical case in which expertise is associated with greater variability of an aspect of movement kinematics. The relative variability of backswing and downswing duration (standard deviation as a percent of movement time) was assessed for experienced and novice field hockey players performing a drive of an approaching ball. The experienced group exhibited higher relative variability of backswing duration than the novice group. It is argued that this variability is functional (in the sense that greater backswing duration variability is associated with superior task performance) and may result from the joint effects of players visually controlling movement during its execution (Bootsma 1988) and the experienced subjects' earlier pick-up of relevant information for visual control (cf. Abernethy and Russell 1987). 相似文献
