Dispositional Optimism in Chinese People: What Does the Life Orientation Test Measure?

The Life Orientation Test was back-translated to Chinese and administered to a sample of college students (N = 314) and a sample of normal adults (N = 306) along with measures of personality and symptoms. When subject to factor analysis, the positive items (representing optimism) and the negative items (representing pessimism) emerged as two separate factors. Empirically, optimism and pessimism were moderately correlated and had unique contributions to the explanation of personality and symptom measures, so that the total score of C-LOT was a better predictor of criterion measures than either optimism or pessimism alone. However, C-LOT's relationship with symptoms was eliminated after negative affectivity was controlled in the student sample, but not in the adult sample, thus suggesting some confounding with negative affectivity. Further research is required to improve the measurement of optimism in Chinese people and to clarify the relationship between optimism and pessimism.     

The Use of Structured Clinical Interviews for Assessment in Counseling

The purpose of this article is twofold: to summarize some of the major issues concerning structured clinical interviews and to review data available on some of the most widely used interview schedules. One of the key challenges with the practitioner—scientist approach to counseling is the ability to compare information from a variety of clients and counselors. A structured clinical interview can be considered an empirically driven instrument that has preestablished questions and scoring procedures that make it a useful assessment tool. Through its use, comparisons can be made among clients, and the reliability of assessment and diagnosis can be increased.     

At-Risk Urban High School Students' Commitment to Career Choices

The purpose of this study was to examine the commitment to career choices process for at-risk urban high school students. Data from 189 at-risk urban high school students were sampled. Results indicated that students' level of commitment to their career choices was related to their vocational identity, their need for occupational information, their perceived barriers to occupational goals, and the number of occupations they considered. The tendency to foreclose was related to the adherence to career myths. Implications and limitations for career theory, research, and practice are addressed.     

GENDER, JEALOUSY, AND REASON

Abstract— Research has suggested that men are especially bothered by evidence of their partner's sexual infidelity, whereas women are troubled more by evidence of emotional infidelity. One evolutionary account (Buss, Larsen, Westen, & Semmelroth, 1992) argues that this is an innate difference, arising from men's need for paternity certainty and women's need for male investment in their offspring. We suggest that the difference may instead be based on reasonable differences between the sexes in how they interpret evidence of infidelity. A man, thinking that women have sex only when in love, has reason to believe that if his mate has sex with another man, she is in love with that other. A woman, thinking that men can have sex without love, should still be bothered by sexual infidelity, but less so because it does not imply that her mate has fallen in love as well. A survey of 137 subjects confirmed that men and women do differ in the predicted direction in how much they think each form of infidelity implies the other, proposing innate emotional differences may, therefore, be gratuitous.     

Work and Family Variables, Entrepreneurial Career Success, and Psychological Well-Being

The study examines the influence of work and family variables on the career success and psychological well-being of 111 men and women entrepreneurs. The results show that work-domain variables account for significant variation in time commitment to work, whereas family-domain variables explain substantial variation in time commitment to family. Time commitment to work and time commitment to family play an important role in mediating the effects of gender, work and family characteristics, and role demands on work-to-family conflict and family-to-work conflict. These two types of work–family conflict in turn mediate the effects of time commitment to work and family and selected work and family variables on entrepreneurs’ career success and life stress. Implications of the findings and directions for further research are discussed.     

Effects of high-pass and low-pass spatial filtering on face identification

If face images are degraded by block averaging, there is a nonlinear decline in recognition accuracy as block size increases, suggesting that identification requires a critical minimum range of object spatial frequencies. The identification of faces was measured with equivalent Fourier low-pass filtering and block averaging preserving the same information and with high-pass transformations. In Experiment 1, accuracy declined and response time increased in a significant nonlinear manner in all cases as the spatial-frequency range was reduced. However, it did so at a faster rate for the quantized and high-passed images. A second experiment controlled for the differences in the contrast of the high-pass faces and found a reduced but significant and nonlinear decline in performance as the spatial-frequency range was reduced. These data suggest that face identification is preferentially supported by a band of spatial frequencies of approximately 8-16 cycles per face; contrast or line-based explanations were found to be inadequate. The data are discussed in terms of current models of face identification.     

Choice of extinction-signalling stimuli by rats

Rats in a two-lever situation were exposed to alternating periods of intermittent reinforcement and extinction. Extinction periods were either unsignalled or were signalled by a response-produced stimulus. The signal was sometimes a stimulus paired with food delivery in the reinforcement periods and sometimes a stimulus that occurred only in extinction periods. Both kinds of signal accelerated extinction relative to the unsignalled condition. When the signal was the stimulus paired with food in reinforcement periods, the rats tended to prefer the lever that gave that signal even though the signal accelerated extinction. There was no comparable effect for the stimulus that occurred only in extinction periods; when this signal was contingent on only one of the two levers, the rats either avoided it (Experiment 3) or were indifferent (Experiment 4). It is concluded that a stimulus can be a “secondary reinforcer” as measured by preference, even though it decreases resistance to extinction; the implications are discussed with reference to formal theories of choice behavior.
