Abstract— Subjects' judgments of the mean of 12 scores were influenced by the way in which the scores were dichotomized. The estimated mean was higher when the three highest scores formed one group (e.g., payments for women) and the nine lowest formed the other (e.g., payments for men) than when the nine highest were one group and the three lowest the other. We call this phenomenon the Will Rogers Illusion (WRI). The WRI occurred only when estimates of the subgroup means were made prior to the estimates of the mean of the whole group. When the latter mean was judged first, the WRI was reversed. These and other data indicate that the means of subgroups can influence judgments of group means, a finding that is relevant to research on social stereotypes. 相似文献

Increases in self-attention as a function of decreases in the relative size of one’s subgroup in a heterogeneous group context
have been shown to result in increased regulation of behavior toward social (normative) standards for behavior. The present
study demonstrated increased regulation of behavior toward a personal standard for behavior as a function of variations in
group composition. One hundred twenty-five subjects individually completed the Creativity subscale of Scott’s Personal Value
Scale assessing attitudes toward originality. They then completed a word-association task in groups ranging in size from 2
to 8. Originality of word-associations was determined by reference to previously established word-association norms and norms
based on frequency of responses given in the present study. Results indicate that originality in responses increase as the
relative size of one’s own subgroup decreases (indexing increases in self-attention) for subjects who value originality. Discussion
centers on the distinction between experimentally manipulated public and private self-attention and standards that are adopted
for behavioral self-regulation.

A review of the literature suggests that a paucity of information exists regarding how culture-specific issues such as being both Black and gifted influence the psychological needs and personality development of gifted Black students. Stellar attempts, however, are currently underway to develop theories and perspectives of racial identity development among Black students. These theories and perspectives are discussed in an attempt to understand and address the psychological and social needs of gifted Black students. 相似文献

This study investigated the psychological and physical health status of 265 crew members on two U.S. Navy ships (a guided
missile cruiser and a frigate on convoy escort duty for tankers under U.S. flag) during the Persian Gulf conflict at four
time periods during combat-ready operations on a single day. Findings suggest that adaptation occurs to extreme stressors
associated with sustained operations. Suggestions are made relative to measures that may minimize psychological and physical
conditions that adversely affect performance under conditions of heavy stress.

The authors studied employment and roles of master's-level counselors in employee assistance programs (EAPs) and the services offered by different types of EAP organizations. The study focused on programs, workshops and seminars: assessment; counseling; consultation; and evaluation and marketing services offered by EAPs. Master's-level counselors were found to be similar to those with Master's of Social Work (MSW) degrees in employment rate and percentage of EAP staff. Both groups were the most frequently employed and constitute the greatest percentage of the professional mental health staff in EAPs. Also, counselors were found to be involved in all of the service areas studied within each type of EAP. Differences in counselors' roles among EAP types are discussed. 相似文献

The authors evaluated the separate and combined effects of study skills training and career counseling on student retention. Participants who were at high risk for dropping out of college were randomly assigned to one of four treatment or control conditions. The study-skills-alone treatment had a significant impact on retention; all of these participants continued their enrollment in the following two semesters. Career-counseling-alone and a combined (study skills plus career counseling) treatment did not register significant effects. Participants who received the study-skills-alone treatment also achieved significantly greater academic success; 88% had grade point averages (GPAs) equal to or greater than 2.0, whereas most other treatment and control participants had GPAs lower than 2.0 and were placed on academic probation. Issues relevant to the construct validity of these changes are discussed. 相似文献

In this study the authors investigated differences in the family environments of high- and low-trait angry college students. High-trait angry students described their family environments as significantly less cohesive, less emotionally expressive, more conflictual, and more disorganized than did their low-trait angry counterparts. Implications of the findings to the counseling of students with anger-related problems are discussed. 相似文献

The recent accumulation of self-report measures of borderline personality disorder (BPD) affords the opportunity to evaluate both the construct validity of the concept and the quality of these measures. This study examines the relationship among three recently developed self-report instruments for assessing BPD from the Personality Assessment Inventory (PAI; Morey, 1991), the MMPI Personality Disorders Scales (MPD; Morey, Waugh, & Blashfield, 1985), and the Bell Object Relations Inventory (BORI: Bell, Billington, & Becker, 1986). Data on the three measures were provided by 119 undergraduate subjects from a southeastern university. A correlational analysis addresses the convergence of these measures of BPD, their divergence from measures of different but related traits, and their independence from variance due to method. Application of the Campbell-Fiske (1959) criteria indicates adequate convergence for all the BPD measures but a lack of discriminant validity for the BORI scales. The fit of the data to a structural model of construct validity is tested using confirmatory factor analysis, and these results are consistent with the hypothesis of a latent borderline trait factor independent of measurement method factors. In sum, the construct validity of the borderline personality concept using self-report methodologies receives support, and a strong association between borderline personality and paranoid phenomena is also suggested. 相似文献
