Ethical dimensions of group leadership

In Conclusion This article has attempted to identify some of the basic life values that can provide guidelines for the ethically responsible group leader. The value guidelines have support in both psychological and religious knowledge. Such values put the leadership of groups in a frame of reference that indicates that growth of persons, freedom of will, use of man's mind, meaningful fellowship, and the importance of the individual are the dynamic dimensions of qualitative group functioning in today's organization.     

Subitizing and similarity: Toward a pattern-matching theory of enumeration

Pattern-matching theories of subitizing claim that subjects enumerate displays with small numerosities by retrieving numerical responses associated with similar displays experienced in the past. Such retrieval implies that displays with small numerosities are similar to other displays of the same numerosity and dissimilar to other displays of different numerosities. These hypotheses were tested by having subjects rate the similarities of displays of dot patterns with numerosities in the range of 1-10. One group of subjects rated patterns of the same numerosity. Their ratings were higher for patterns in the subitizing range (numerosities of 1-3) than for patterns beyond the subitizing range (numerosities of 4-10). Another group rated patterns of different numerosities. Their ratings were lower in the subitizing range than beyond the subitizing range. An analysis based on multidimensional scaling suggested that numerosity could be retrieved accurately for displays of 1-3 dots, but not for displays of 4-10 dots.     

Projectivist utilitarianism and the satisfaction of desire

N. M. L. Nathan's argument that IDP utilitarianism, if universally adopted, is inconsistent, does not succeed. The argument requires that if an IDP utilitarian has only self-regarding desires, then none of these desires can be informed. This rests on a partial misuse of the expression satisfaction of desire. For an individual attempting to realize his self-regarding desires, the satisfaction of the satisfaction of a desire is unmeaning. The naming of an object of the desire is an intrinsic part of the phrase satisfaction of desire. Further, contrary to Nathan's claim, this suggestion does not trivialize IDP utilitarianism.

Explanatory style and gambling: How pessimists respond to losing wagers

Fifty-three patrons of a harness racing track completed two measures of explanatory style prior to an afternoon's races. One measure assessed general explanatory style, using bad events taken from the Attributional Style Questionnaire, and the other measure assessed betting-specific explanatory style, using bad events specific to harness race betting. Subjects then kept a diary during the first eight races. After each race, they reported how much they had bet, whether they had won or lost, the major cause of the outcome, their confidence about winning future bets, and whether they were ruminating about past or future races. Explanatory style assessed in both ways had similar correlates. Explanatory style predicted the specific attributions made by subjects for losses. Pessimistic explanatory style (internal + stable + global attributions) predicted rumination following a lost bet, but it was unrelated to expressed confidence. Rumination after a loss was in turn associated with larger wagers on subsequent races and a tendency toward less successful wagers. These results clarify one way in which pessimistic explanatory style results in helplessness, and suggest a path by which problematic gambling may develop.     

A reexamination of the faithful subject role

Fillenbaum (Journal of Personality and Social Psychology, 1966, 4, 532–537; Fillenbaum & Frey, Journal of Personality, 1970, 38, 43–51) has proposed that a relatively large number of subjects within certain experiments will adopt a faithful subject role, that is, they will intentionally avoid basing their behavior on any suspicions they may have regarding the experimenter's hypothesis. However, examination of the studies on which this conclusion was based casts doubt on whether Fillenbaum's subjects were truly faithful or whether they may have become aware of the nature of the deception after all opportunity for awareness to influence their responses had passed. To test this hypothesis, awareness measures were administered to subjects either before they took an incidental learning test or (as in Fillenbaum's studies) after the test. As predicted, fewer subjects were classified as faithful in the first condition than in the second. It was concluded that, in fact, very few if any subjects are actively faithful. Discussion also concerned the problems associated with role analyses of subject behavior.     

Lying in the elementary school years: verbal deception and its relation to second-order belief understanding

The development of lying to conceal one's own transgression was examined in school-age children. Children (N=172) between 6 and 11 years of age were asked not to peek at the answer to a trivia question while left alone in a room. Half of the children could not resist temptation and peeked at the answer. When the experimenter asked them whether they had peeked, the majority of children lied. However, children's subsequent verbal statements, made in response to follow-up questioning, were not always consistent with their initial denial and, hence, leaked critical information to reveal their deceit. Children's ability to maintain consistency between their initial lie and subsequent verbal statements increased with age. This ability is also positively correlated with children's 2nd-order belief scores, suggesting that theory of mind understanding plays an important role in children's ability to lie consistently.     

Virtual and drawing structures for the Müller-Lyer illusions

This research assessed the relative contribution of 3-D virtual structure that generated the stimulus drawings (scene-based and picture-based theories) and 2-D structure of the drawings (object-based theories). Virtual structures were right-angle convex and concave corners in front of and behind the picture plane, respectively. Virtual corner size was manipulated directly (Experiment 1) and indirectly by manipulating drawing station point distance (Experiments 2 and 3), corner depth (Experiment 4), and corner distance from the picture plane (Experiments 5 and 6). Experiments 2 and 4 held the size of the projected corner edge (interior target line) constant, causing virtual corner size to vary, whereas Experiments 3, 4, 5, and 6 held size of the virtual corners constant, causing size of the projected corner edge or interior target line to vary. Subjects reproduced the length of the projected corner edge (interior target line). The illusions (difference between reproduced size of the projected corner edge and T-junction control) were generally well fit by the weighted sum of virtual corner size and size of the projected corner edge, but the projected distance between boundary line terminations (intertip distance) appeared as an additional contributing factor in Experiments 5 and 6. The implications of this methodological approach are discussed for theories of the illusions.     

Projecting perfection by hiding effort: supplementing the perfectionistic self-presentation scale with a brief self-presentation measure

Extensive research has illustrated the relevance of individual differences in perfectionistic self-presentation, but there has been little work on how perfectionistic self-presentation is expressed. The current research addressed this issue by examining the tendency to project a perfectionistic image by hiding effort. This research develops and evaluates a brief unifactorial measure as an extension of perfectionistic self-presentation. It is shown that the Perfectionistic Self-Presentation Hiding Effort Scale is reliable and valid in terms of its links with multidimensional perfectionism dimensions. Further, individual differences in seeming perfect while hiding effort accounted for unique variance in depression and social anxiety. Factors and processes that contribute to attempting to seem perfect while hiding effort are discussed.
