Expectancy theory predictions and behaviorally anchored scales of motivation: An empirical test of engineers

The present study involved 375 engineers and 110 supervisory team engineers. A partial replication of the Arvey and Neel (1974) and the Landy and Guion (1970) research involving behaviorally anchored scales of motivational effort was first investigated with a number of engineering groups. In addition, a behaviorally specific motivational effort rating scale was developed for and tested in the company. The organizational specific scale results were examined and compared to those generated from the Landy and Guion (1970) scale. It was found that the organizationally specific and engineer relevant scale is a better predictor of two types of expectancies.     

Two tests of Maslow's theory of need fulfillment

In a two-part test of Maslow's theory of human motivation, two relationships were explored: (1) the relationship between need importance and need deficiencies, and (2) the relationship between need deficiencies and life satisfaction. The subjects were groups of women college graduates in three types of occupations: professional-managerial, clerical-sales, and homemaking. In the first study, group differences in actual deficiencies did not support the hypothesis that need importance is negatively correlated with need deficiencies. Rankings of the deficiencies for the three groups, however, were consistent with the hypothesized relationship, as were the small but significant correlations that were obtained between need importance and deficiency values. In the second study, the findings gave partial support to Maslow's theory in that a significant relationship was found between need fulfillment and life satisfaction for two of the three occupational groups. The findings of both studies are discussed in relation to considerations in women's career development.     

Personality traits and critical thinking skills in college students: empirical tests of a two-factor theory

The two-factor theory defines critical thinking skills as a combined effect of cognitive abilities and personality dispositions. Although the available research supports the association between critical thinking and measures of cognitive ability, the specific traits contained in the dispositional factor have not been clearly identified through empirical research. In Study 1,101 undergraduate students completed the Watson-Glaser Critical Thinking Appraisal (WGCTA), three subtests of the Wechsler Adult Intelligence Scale-Third Edition, and the revised NEO Personality Inventory. Hierarchical multiple regression analyses showed that Openness to Experience scores accounted for significant incremental variance in WGCTA scores beyond that accounted for by Similarities subtest scores. In Study 2, similar analyses of data from 105 students also showed significant incremental effects for Openness to Experience, even after more variance in the cognitive factor was accounted for by the Verbal Comprehension Index. Implications of these findings for the enhancement of critical thinking skills in college students are discussed.     

Two dogmas of empirical justification

Nearly everyone agrees that perception gives us justification and knowledge, and a great number of epistemologists endorse a particular two‐part view about how this happens. That view is that perceptual beliefs get their justification from perceptual experiences, and that they do so by being based on them. Despite the wide acceptance of these two views, I think that neither has very much going for it; on the contrary, there's good reason not to believe either one of them.     

Four empirical tests of Unconscious Thought Theory

According to Unconscious Thought Theory, people make better decisions after unconscious than after conscious thought (Dijksterhuis, Bos, Nordgren, & van Baaren, 2006a). Unconscious Thought Theory yields four specific predictions. First, an exact replication of Dijksterhuis et al. (2006a) study should indicate that unconscious decisions are superior to conscious decisions. Second, decisions should improve with duration of conscious thought. Third, unconscious decisions should be superior to conscious decisions, even if unconscious decisions are deliberated while having access to information. Fourth, unconscious decisions should be based on a weighting strategy. We report results of four studies, featuring 480 participants, that yield no evidence in favor of these predictions. Therefore our findings cast doubt on Unconscious Thought Theory and its advice to base decisions on unconscious thought. The results of our studies suggest that it is better to base decisions on conscious thought while having access to information.     

The concept of adaptation-level in psychological research

Vuorinen, R. The concept of adaptation-level in psychological research. Scand. J. Psychol., 1973, 14, 228–240.- Helson's adaptation-level theory (ALT) is appraised as a general theory of psychology. The reformulated Fechner law underlying ALT is shown to be untenable and the conceptual status of AL is shown to be self-contradictory. The ambiguous measures and the inconsistent theoretical definitions proposed for AL are found to limit the scope of ALT. Reasons for its flexibility and claimed heuristic value are analyzed and potential sources of confusion are suggested. Some defects of ALT are likely to be shared by other behaviouristic theories since they follow from a commitment to the strict S-R model.     

Mirror reversal: empirical tests of competing accounts

In a mirror, left and right are said to look reversed. Surprisingly, this very familiar phenomenon, mirror reversal, has still no agreed-upon account to date. This study compared a variety of accounts in the light of empirical data. In Experiment 1, 102 students judged whether the mirror image of a person or a character looked reversed or not in 15 settings and also judged the directional relation between its components. In Experiment 2, 52 students made the reversal judgements in 13 settings. It was found for the first time that a substantial proportion of people denied the left-right mirror reversal of a person, whereas virtually all of them did recognize that of a character. This discrepancy strongly suggested that these two kinds of mirror reversal are produced by different processes, respectively. A number of findings including this discrepancy clearly contradicted two accounts that are currently active: the one based on the priority of the up-down and front-back axes over the left-right axis, and the one based on the physical rotation of an object. All the findings were consistent with an account that considered mirror reversal a complex of three different phenomena produced by three different processes, respectively.     

Using SAT-grade and ability-job performance relationships to test predictions derived from stereotype threat theory

To examine the generalizability of stereotype threat theory findings from laboratory to applied settings, the authors developed models of the pattern of relationships between cognitive test scores and outcome criteria that would be expected if the test scores of women and minority group members were affected by stereotype threat. Two large data sets were used to test these models, one in an education setting examining SAT-grade relationships by race and gender and the other in a military job setting examining Armed Services Vocational Aptitude Battery-job performance relationships by race. Findings were not supportive of the predictions arising from stereotype threat theory, suggesting caution in positing threat as a key determinant of subgroup mean test score differences in applied settings.
