Making Probabilistic Relational Categories Learnable

Theories of relational concept acquisition (e.g., schema induction) based on structured intersection discovery predict that relational concepts with a probabilistic (i.e., family resemblance) structure ought to be extremely difficult to learn. We report four experiments testing this prediction by investigating conditions hypothesized to facilitate the learning of such categories. Experiment 1 showed that changing the task from a category‐learning task to choosing the “winning” object in each stimulus greatly facilitated participants' ability to learn probabilistic relational categories. Experiments 2 and 3 further investigated the mechanisms underlying this “who's winning” effect. Experiment 4 replicated and generalized the “who's winning” effect with more natural stimuli. Together, our findings suggest that people learn relational concepts by a process of intersection discovery akin to schema induction, and that any task that encourages people to discover a higher order relation that remains invariant over members of a category will facilitate the learning of putatively probabilistic relational concepts.

Creative reasoning in formal discussion

Systems of formal dialectics articulate methods of conflict resolution. To this end they provide norms to regulate verbal exchanges between the Proponent of a thesis and an Opponent. These regulated exchanges constitute what are known as formal discussions.One may ask what moves, if any, in formal discusions correspond to arguing for or against the thesis. It is claimed that certain moves of the Proponent's are properly designated as arguing for the thesis, and that certain moves of the Opponent purport to criticize the tenability or the relevance of the reasons advanced. Thus the usefulness of formal dialectic systems as models for reasonable argument is vindicated.It is then proposed to make these systems more realistic by incorporating in them a norm of Creative Reasoning that removes the severe restrictions to which the Proponent's arguing was hitherto subject. As a consequence, a certain type of irrelevant reason is no longer automatically excluded. Therefore, it is proposed to extend the Opponent's rights to exert relevance criticism. The new dialectic systems are shown to be strategically equivalent to the original ones. Finally, it is stressed that the Opponent's criticism should not be designated as arguing against the thesis. The Opponent criticizes, but does not argue.     

Influence of executive functioning difficulties on verbal aggression in adolescents: Moderating effects of winning and losing and increasing and decreasing levels of provocation

We examined the extent to which executive functioning difficulties were related to verbal aggression under conditions of gradually increasing or decreasing provocation over both winning and losing trials. Sixty adolescent boys and girls completed a modified Taylor aggression paradigm in which verbally offensive remarks were sent and received. Results showed (a) that during increasing levels of provocation, verbal aggression increased on both winning and losing trials, (b) that verbal aggression decreased during decreasing levels of provocation but only on losing trials, and (c) that difficulties on two measures of executive functioning were related to verbal aggression, but only in the context of increasing verbal provocation. Individuals with executive functioning difficulties responded with more verbal aggression than did individuals with less severe executive functioning difficulties. Results have implications for the manner in which provocation is studied and for understanding the conditions in which executive functioning difficulties contribute to verbal aggression. Aggr.

先秦兵家决策心理思想研究

先秦兵家具有丰富的决策心理思想,主要观点如下：1“知彼知己,百战不殆”──全面信息管理心理思想。2“校之以计,而索其情”──全方位收集分析信息;这段时期兵家提出的收集信息方法和手段可以概括为以下几点：（1）分析推断;（2）观察法;（3）用间法;（4）侦察法。3“多算胜,少算不胜”的决策心理思想：先秦兵家的决策心理思想是以“全胜而非战”为目标,以全面的信息管理为前提,并且包含有三条原则：“善之善者”的优选原则;“践墨随敌”的调控原则;“奇正相生”的变化原则。     

Behavioral Consequences of Fluctuating Group Success: An Internet Study of Soccer-Team Fans

Abstract

The authors tested the hypothesis that fans of a sports team avoid private contact with their team when it is unsuccessful (cutting off reflected failure, or CORF), whereas fans actively seek private contact with their team when it is successful (basking in reflected glory, or BIRG). During the 2nd half of the 1999–2000 soccer season, the authors registered the number of visitors who had surfed the Web sites of 16 Belgian and 18 Dutch 1st-division teams on the 1st working day following a championship game. The authors obtained 586 valid measurements, which were transformed into z scores for each team separately. In line with the hypothesis, there were significantly more visitors after the teams won (BIRG) than after they lost (CORF). The effects of game outcome were not mediated by pregame expectations or by the size of the wins or losses.

Sportsmanship

What is sportsmanship? Following Keating, we may say that sportsmanship is conduct befitting a person involved in sports. This raises the question of what kind of activity exactly sport is. This is notoriously difficult to answer, but roughly speaking, sport is a rule-governed activity that is about excellence, an understanding of how to play the game, and, in competitive sports, winning. Accordingly, there are four elements of sportsmanship: fairness, equity, good form and the will to win. These four elements are equally important and not reducible to one another. Yet, the will to win is in systematic conflict with the other three elements. Hence, sportsmanship is not only compromised of these four elements, but also requires that a balance be held between them.
