The Mini-IPIP, a 20-item short form of the 50-item International Personality Item Pool-Five-Factor Model measure (Goldberg, 1999), was developed and validated across five studies. The Mini-IPIP scales, with four items per Big Five trait, had consistent and acceptable internal consistencies across five studies (= at or well above .60), similar coverage of facets as other broad Big Five measures (Study 2), and test-retest correlations that were quite similar to the parent measure across intervals of a few weeks (Study 4) and several months (Study 5). Moreover, the Mini-IPIP scales showed a comparable pattern of convergent, discriminant, and criterion-related validity (Studies 2-5) with other Big Five measures. Collectively, these results indicate that the Mini-IPIP is a psychometrically acceptable and practically useful short measure of the Big Five factors of personality. 相似文献

Anisomycin infused into the hippocampus fails to block "reconsolidation" but impairs extinction: the role of re-exposure duration

Recent studies have reported new evidence consistent with the hypothesis that reactivating a memory by re-exposure to a training context destabilizes the memory and induces "reconsolidation." In the present experiments, rats' memory for inhibitory avoidance (IA) training was tested 6 h (Test 1), 2 d (Test 2), and 6 d (Test 3) after training. On Test 1 the rats were either removed from the shock compartment immediately after entry or retained in the shock context for 200 sec, and intrahippocampal infusions of the protein synthesis inhibitor anisomycin (75 microg/side) were administered immediately after the test. Anisomycin infusions administered after Test 1 impaired IA performance on Test 2 in animals given the brief re-exposure, but impaired extinction in animals exposed to the context for 200 sec. Rats with anisomycin-induced retention impairment on Test 2 demonstrated spontaneous recovery of retention performance on Test 3, whereas rats showing extinction on Test 2 showed further extinction on Test 3. The findings indicate that post-retrieval administration of anisomycin impairs subsequent retention performance only in the absence of extinction and that this impairment is temporary. 相似文献

Four types of analysis are commonly applied to data from structured Rater x Ratee designs. These types are characterized by the unit of analysis, which is either raters or ratees, and by the design used, which is either between-units or within-unit design. The 4 types of analysis are quite different, and therefore they give rise to effect sizes that differ in their substantive interpretations. In most cases, effect sizes based on between-ratee analysis have the least ambiguous meaning and will best serve the aims of meta-analysts and primary researchers. Effect sizes that arise from within-unit designs confound the strength of an effect with its homogeneity. Nonetheless, the authors identify how a range of effect-size types such as these serve the aims of meta-analysis appropriately. 相似文献

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

In risky decision situations, many decision makers search for risk-defusing operators (RDOs). An RDO is an action intended by the decision maker to be performed additionally to a specific alternative and is expected to decrease the risk. Pre-event RDOs (e.g., vaccination) have to be applied before a negative event (e.g., infection) occurs. Post-event RDOs do not need to be initiated before and unless the event happens (e.g., medical treatment). For the successful application of Post-event RDOs, the negative event must be detected in time. Two experiments investigated the effect of uncertainty in the detection of the negative event. In Experiment 1, only a small minority of subjects noted this uncertainty without a cue, and even with cue, only a minority actively searched for probability information. In Experiment 2, the probability for correctly detecting the negative event was varied. When detection was certain, most subjects chose the alternative with a Post-event RDO, whereas this percentage decreased significantly with decreasing probability of correct detection. Also, in the conditions with a more extreme negative outcome, less decision makers chose the alternative with the Post-event RDO. 相似文献

In a study of 82 White counselor trainees enrolled in 3 graduate programs, gender and the lowest stage of cognitive development were found to significantly contribute to the variance in lower levels of the White racial identity. Male trainees who tended to think in dichotomous terms and look to authority to provide the correct answers tended to report attitudes about race reflected in lower levels of White racial identity. Significant relationships were not found between higher stages of cognitive development and higher levels of White racial identity. Implications for training are presented and discussed. 相似文献

In a study of African American (n = 208) urban high school students, grade point average (GPA) and specific strategies for coping with day-to-day stressors were found to be significantly related to psychological adjustment. Students who had higher GPAs tended to use family members as a means of solving problems, minimized problems by the use of humor, and used relaxation activities less often were found to have the most positive psychological adjustment, as measured by the index score of the Affects Balance Scale (ABS). Reported negative affect was not found to be significantly influenced by coping style, whereas positive affect was. 相似文献

Researchers identified personality typologies (Myers-Briggs Type Indicator; Myers, 1962) among urban African American high school Juniors and seniors (n = 173). Introverted Sensing Thinking Judging (ISTJ) and the Introverted Sensing Thinking Perceptive (ISTP) were the two most represented typologies. Implications for school counselors, teachers, and teacher and counselor educators are discussed. 相似文献

In selection research and practice, there have been many attempts to correct scores on noncognitive measures for applicants who may have faked their responses somehow. A related approach with more impact would be identifying and removing faking applicants from consideration for employment entirely, replacing them with high-scoring alternatives. The current study demonstrates that under typical conditions found in selection, even this latter approach has minimal impact on mean performance levels. Results indicate about .1 SD change in mean performance across a range of typical correlations between a faking measure and the criterion. Where trait scores were corrected only for suspected faking, and applicants not removed or replaced, the minimal impact the authors found on mean performance was reduced even further. By comparison, the impact of selection ratio and test validity is much larger across a range of realistic levels of selection ratios and validities. If selection researchers are interested only in maximizing predicted performance or validity, the use of faking measures to correct scores or remove applicants from further employment consideration will produce minimal effects. 相似文献
