Motivation in Personal Construct Theory: A Conceptual Critique

Kelly's attempt to derive apparently motiwtional phenomena (hostility, guilt, etc.) solely from the confirmation or disconfirmation of personal constructs cannot adequately explain such phenomena. His account of hostility assumes that some beliefs are so resistant to change that the person seeks to compel confirmation of them; however, this resistance is incompatible with Kelly's own Choice Corollary. Anxiety is said to derive from the fact that disconfirmation would leave one's world in chaos, but “chaos” is shown to be an illogical concept. Humor, in turn, cannot be explained just by cognitive incongruity, since incongruity may as well lead to anxiety or hostility. Finally, guilt cannot be explained without reference to underlying fears of punishment and their rationalization in terms of supposedly objective moral concepts. Nevertheless, Kelly's Repertory Grid technique, supplemented by laddering, may be useful in indicating primary needs, moral convictions, and sources of anxiety.

Performance Self-Predictions: The Impact of Expectancy Strength and Incentives1

Performance self-predictions represent an individual's anticipated level performance on an upcoming task. This study focused on the accuracy of these predictions, as well as subjective reactions to making them under varying expectancy and incentive conditions. Results indicate that performance-contingent incentives had a positive effect on task performance, but a negative effect on preferences for making performance predictions. Expectancy strength also influenced these predictions, their subjective interpretations, and task performance. Additional results address the role of other task-relevant judgments (e.g., self-assessed ability and intended effort) when predicting one's performance on a task. Implications of these findings for work motivation and judgment accuracy are discussed.     

Use of binaural cues for sound localization in two species of Phyllostomidae: the Greater spear-nosed bat (Phyllostomus hastatus) and the Short-tailed fruit bat (Carollia perspicillata)

Unlike humans, not all mammals use both of the binaural cues for sound localization. Whether an animal uses these cues can be determined by testing its ability to localize pure tones; specifically, low frequencies are localized using time-difference cues, and high frequencies are localized using intensity-difference cues. We determined the ability to use binaural cues in 2 New World bats, Phyllostomus hastatus, large omnivores, and Carollia perspicillata, small frugivores, by testing their tone-localization ability using a conditioned avoidance procedure. Both species easily localized high-frequency tones, indicating that they could use the interaural intensity-difference cue. However, neither species was able to use the phase-difference cue to localize either low-frequency pure tones or amplitude-modulated tones (which provided an envelope for additional time analysis). We now know of 3 bat species that cannot use binaural time cues and 2 that can. Further exploration of localization in bats may provide insight into the neural analysis of time cues in species that do not hear low frequencies.     

The influence of suggestibility on memory

We provide a translation of Binet and Henri's pioneering 1894 paper on the influence of suggestibility on memory. Alfred Binet (1857-1911) is famous as the author who created the IQ test that bears his name, but he is almost unknown as the psychological investigator who generated numerous original experiments and fascinating results in the study of memory. His experiments published in 1894 manipulated suggestibility in several ways to determine effects on remembering. Three particular modes of suggestion were employed to induce false recognitions: (1) indirect suggestion by a preconceived idea; (2) direct suggestion; and (3) collective suggestion. In the commentary we suggest that Binet and Henri's (1894) paper written over 115 years ago is still highly relevant even today. In particular, Binet's legacy lives on in modern research on misinformation effects in memory, in studies of conformity, and in experiments on the social contagion of memory.     

Psychological variables underlying political orientations in an old and a new democracy: A comparative study between Sweden and Latvia

This study examines in detail the psychological variables underlying ideological political orientation, and structure and contents of this orientation, in Sweden and Latvia. Individual political orientation is conceptualized on two dimensions: acceptance vs. rejection of social change and acceptance vs. rejection of inequality. Swedish (N = 320) and Latvian (N = 264) participants completed measures of political orientation, Social Dominance Orientation (SDO), Right Wing Authoritarianism (RWA), self vs. other orientation, tolerance for ambiguity, humanism and normativism, core political values, system justification, as well as moral foundations questionnaire and portrait values questionnaire. The results showed that the relation among the measured variables was similar in both samples. Swedish participants showed stronger endorsement of egalitarian attitudes and social values, whereas we found more self‐enhancing and socially conservative values and attitudes among the Latvian participants.
