When Experts Argue: Explaining the Best and the Worst of Reasoning

Expert reasoning is responsible for some of the most stunning human achievements, but also for some of the most disastrous decisions ever made. The argumentative theory of reasoning has proven very effective at explaining the pattern of reasoning’s successes and failures. In the present article, it is expanded to account for expert reasoning. The argumentative theory predicts that reasoning should display a strong confirmation bias. If argument quality is not sufficiently high in a domain, the confirmation bias will make experts tap into their vast knowledge to defend whatever opinion they hold, with polarization and overconfidence as expected results. By contrast, experts should benefit even more from the power of group discussion to make the best of the confirmation bias—when they genuinely disagree that is, otherwise polarization is again likely to ensue. When experts interact with laymen other mechanisms can take the lead, in particular trust calibration and consistency checking. They can yield poor outcomes if experts do not have a sustained interaction with laymen, or if the laymen have strong opinions when they witness a debate between experts. Seeing reasoning as a mechanism of epistemic vigilance aimed at finding and evaluating arguments helps make better sense of expert reasoning performance, be it in individual ratiocination, in debates with other experts, or in interactions with laymen.     

Usage of and Compliance with Power Tactics in Routine Versus Nonroutine Work Settings

This study examines situational determinants of power usage and compliance derived from the Interpersonal Power Interaction Model. Organizations where routine tasks predominate were compared with those where complex tasks prevail. Samples of workers (N = 194) and supervisors (N = 100) from four companies representing routine tasks and complex ones completed three versions of the Interpersonal Power Inventory (Raven, Schwarzwald & Koslowsky, 1998). Results indicated that in settings where routine tasks predominate usage of and compliance with harsh power tactics was greater than in complex ones. Yet, soft tactics were not related to task complexity. It was also found that rank and tactics interacted. Regardless of settings, supervisors as compared to subordinates reported more frequent usage of soft tactics and less frequent usage of harsh ones. The discussion suggests a mechanism for understanding these patterns.

The Need for Power and Fear of Assertiveness in English-Speaking South African Female Graduates

The present study demonstrated that Winter's (1973) power arousal procedure and scoring system for the need for power, which were developed in the United States, are valid for English-speaking South African female graduates. Subjects in whom the need for power had been aroused by a prerecorded inspirational speech (n = 20) had significantly higher n Power scores than matched nonaroused subjects (n = 20), T ²(8, 31) = 56.17, p ≤ .01. Further, it was argued that the fear of assertiveness is a component of the need for power, and a scoring system for measuring this motive was suggested. Fear of assertiveness was shown to correlate significantly with various behavioral and dispositional measures of assertiveness, relating especially to a dependency pattern of behavior.     

Perceptions of Assertiveness by High- and Low-Assertive Female College Students

The interpersonal effects of assertive and unassertive behavior on females who scored high and low in self-reported assertion were examined. Subjects from each of the two assertion categories individually interacted with a female confederate trained to act either assertively or unassertively in a structured manner. In analyzing the subjects' impressions of the confederate, no significant differences between high and low assertives on the dimensions of competence, task attraction, social attraction, likability, and desirability were found. Assertive responding appeared less salient to the observer assertee in more naturalistic conditions and its social impact seemed more attenuated when the assertive responding took on a relatively mild form that posed little or no direct social or personal risk to the receiver of the assertive behavior.     

Causal Attributions of Male and Female Performance by Young Children

Males and females in kindergarten and third grade predicted whether a boy or a girl would succeed on a masculine or a feminine task. Some predictions were confirmed; others were not. The children were asked to explain the winner's success by choosing among four determinants of achievement: ability, effort, task ease, and luck. For third graders, luck was more important in determining the success of an unpredicted winner than a predicted winner. For both ages, female success on a masculine task was attributed more to effort than to ability. These findings support attribution theory and indicate that differential perceptions of male and female performance exist in young children.     

THE SHIFT IN POWER WITH AGE Changes in Perception of the Power of Women and Men Over the Life Cycle

Previous research has described an apparent shift in perceived interpersonal power towards equality between men and women later in life. This study investigated (a) whether the shift in power with age would appear in the Israeli kibbutz, (b) the role of the parental emergency in the shift, and (c) whether changes in behaviors or attitudes best account for the shift. One hundred twenty younger and older Israeli women and men, half from the city and half from the kibbutz, wrote TAT stories, which were then rated for overall power of the female and male characters, their power strategies, and their motives. A shift in perceived power with age was found in both the city and the kibbutz. Parental status reduced the power of the woman and increased the power of the man only in the city, whereas the reverse was true in the kibbutz. These results counter the parental emergency explanation for the shift in power with age. Furthermore, older women used traditionally feminine power strategies, but their behavior was evaluated as more powerful than the same behavior in younger women. Thus, it is not the behaviors but rather people's evaluation of the behaviors that changes across the life span of the individual.     

Seeing the World Differently: An Analysis of Descriptions of Visual Experiences Provided by Visual Artists and Nonartists

ABSTRACT: This project examined nonartists', hobby artists', student artists', and professional artists' responses to questions about the visual games and visual analyses they engaged in as adults and their recollections of these experiences from childhood. Findings indicate that in comparison to nonartists, (a) more artists reported these visual perceptual experiences, (b) artists reported having these experiences more often (particularly as adults), and (c) artists provided better examples of these perceptual experiences that were also more vivid and detailed (particularly as adults). These findings suggest an important connection between artists' reports of past and current visual experiences and actual performance on attention and object perception tasks. Our long-term goal is to understand the importance of visual perceptual abilities to the development of artistic talent.     

Male and Female Victims of Male Bullies: Social Status Differences by Gender and Informant Source

We examine two sources of variation in victims’ social adjustment: (a) the informant who identifies a child as victim (i.e., peer, self, or both), and (b) victim gender. Peer and self nominations were provided by 508 fourth and fifth graders from the Midwest U.S. Girls were more likely than boys to be victimized, and victims were evenly distributed among informant source. Self-nominated female victims had lower social status and were involved in more antipathies than their peer-nominated counterparts. Among boys, self-and-peer reported victims had the lowest social status. Having friends was associated with positive social adjustment. Implications are discussed for at-risk victim subgroups: girls whose self-reports of victimization are not validated by others, and boys whose victimization is publicly acknowledged.
