Concealing negative evaluations of a romantic partner's physical attractiveness

Two studies provided evidence that people hide their negative evaluations of their romantic partner's physical attractiveness. This pattern was found using self‐reports of concealment (Study 1) and a behavioral observation measure (Study 2). Participants who engaged in this deception also exhibited elevated speech disfluencies, which is a deception cue. Moderators of concealment were examined. Concealment was especially pronounced for participants high in care for the partner's welfare (Studies 1 and 2), low in commitment (Studies 1 and 2), and high in attractiveness ideals (Study 2). Results suggest that people use deception to regulate their romantic partner's feelings, but that long‐term orientation or desire to maintain closeness may curtail use of this strategy.     

DETERMINATION AND EVALUATION OF RATE MEASUREMENTS IN THE ANALYSIS OF SPACE MEDICAL DATA

Measures of rate of change and of rate of rate of change are developed for application to physiological and psychological data. Examples are given of the use of these measures with heart-rate data for comparisons within and between subjects. It is shown that the measures provide information over and above that offered by means and variances, and that the measures appropriately reflect the impact of external variables.     

Hippocampal injections of amyloid beta-peptide 1-40 impair subsequent one-trial/day reward learning

The injection of amyloid beta-peptide (Abeta) into rat CNS has been reported to induce cellular neuropathology. The present study investigated whether multiple intrahippocampal injections of Abeta 1-40 would impair one-trial/day reward learning 14 days later. Twenty-four male Sprague-Dawley rats, 3-4 months old, were injected with either Abeta 1-40 or distilled water into seven hippocampal sites bilaterally. Ten rats received 3 nmol Abeta 1-40 in 2 microl of distilled water per injection site, while 14 rats received distilled water alone. Following a 9-day recovery period, rats were gradually food deprived to 82% of their initial body weight. Fourteen days after the intrahippocampal injection, all rats received an initial training trial and three subsequent daily retention trials. Rats receiving Abeta 1-40 were significantly impaired on the second retention trial in terms of accuracy (number of unbaited alleys entered) and on the second and third retention trials in terms of speed (reciprocal of latency to reward). Histological analysis showed that Abeta 1-40 injections produced significant neuronal loss and gliosis. Abeta 1-40 immunoreactivity persisted locally at the injection site and in macrophages 2 weeks following the hippocampal injections. These effects appear to be sequence-specific; rats receiving Abeta 1-42 with a scrambled peptide sequence did not differ significantly from rats receiving distilled water alone in retention of the learning task or degree of histological damage.     

EXPERIENCED HIRING VERSUS COLLEGE RECRUITING: PRACTICES AND EMERGING TRENDS

Although much professional and managerial hiring involves experienced workers, previous recruitment research has focused almost exclusively on new college graduates. To remedy this imbalance, 251 staffing professionals were surveyed concerning experienced-versus-college hiring practices in their organizations. Results suggest that a majority of positions requiring a college degree are filled with experienced workers. Experienced hires are evaluated more highly than new graduates on most characteristics (understanding business, knowledge of competition, realistic expectations, technical skills, interpersonal skills, writing skills, work ethic, likelihood of success, personal ethics), although new graduates are evaluated more highly on open-mindedness and willingness and ability to learn new things. Higher proportions of experienced hiring are associated with organizational growth, short-term staffing strategies, older workforces, and less dynamic business environments. Perceived success of experienced hiring is associated with greater use of effective recruitment sources, older workforces, and more competitive salary offers.     

Synaesthesia,creativity and art: What is the link?

It has been suggested that individuals with synaesthesia may show heightened creativity as a result of being able to form meaningful associations between disparate stimuli (e.g. colour, sound). In this study, a large sample (N=82) of people with various kinds of synaesthesia were given two psychometric tests of creativity (Remote Associates Test, Alternate Uses Test) and were also asked about the amount of time engaged in creative arts (visual art, music). There was a significant tendency for synaesthetes to spend more time engaged in creative arts and this was, at least in part, dependent upon the type of synaesthesia experienced. For example, synaesthetes experiencing vision from music were far more likely to play an instrument than their other synaesthetic counterparts. There was no relationship between this tendency and the psychometric measures of creativity, but synaesthetes did outperform controls on one of the two psychometric measures (Remote Associates). We conclude that the tendency for synaesthetes to be more engaged in art is likely to have a different mechanism to psychometric measures of creativity, and that there is no direct link between them. Although synaesthetes may well perform better on some measures of creativity, we suggest that synaesthetes have better bottom‐up access to certain associations, but are not necessarily better able to use them flexibly (in divergent thinking).     

FEMALE VS. MALE ABSENCE RATES: A TEMPORAL ANALYSIS

The purpose of this research is to test the importance of temporal trends within absenteeism data for males and females. The data support previous findings of higher absenteeism rates for women when compared to men. The data also indicate the importance of temporal trends as suggested by Dansereau, Alutto, and Markham (1978). Conclusions are drawn concerning the use of absence rates as dependent variables.     

JOB-RELATEDNESS OF A POSTTRAINING JOB KNOWLEDGE CRITERION USE TO ASSESS VALIDITY AND TEST FAIRNESS

Significant job-relatedness was found for a posttraining job knowledge test criterion using an application of Lawshe's content validity method. The aide test was used as a criterion to assess the predictive validity of a vocabulary test and a civil service test with samples of black ( N = 43) and white ( N = 62) psychiatric aides. Significant validities were found on both tests, but a vocabulary test proved to be the better predictor of the criterion in both samples. The obtained validities were discussed in terms of differential validity, test fairness, and sample size. This study demonstrated that a content validity method could be applied to criteria as well as selection tests. It was concluded that content validity methods may be able to help solve the problem of criterion relevance in validation research by providing quantitative evidence of the job-relatedness of criteria.
