The effect of achievement goals on enjoyment, effort, satisfaction and performance

This study examined the effect of achievement goals and achievement emotions on sport satisfaction, performance and effort among competitive athletes. Participants were 200 athletes. Structural equation modeling was used to test the indirect effect of mastery-approach goals on satisfaction with sport experience and performance, the direct effect of mastery-approach goals on enjoyment and effort, the direct effect of performance-approach and performance-avoidance goals on performance, and the direct effect of mastery-avoidance goals on effort. Results showed a positive direct effect of mastery-approach goals on enjoyment and an indirect effect, through enjoyment, on satisfaction, performance, and effort. We did not find support for the hypothesized effect of performance-approach or performance-avoidance goals on performance. The applied implications of endorsing mastery-approach goals are discussed.     

An experimental analysis of task refusal: A comparison of negative reinforcement contingencies and transitions between academic tasks

The purpose of the study was to do an experimental analysis of academic task refusal for one girl with a developmental disability. Task refusal was analyzed in two experimental analyses. First, an analysis testing if the behavior was maintained by negative reinforcement, and the second, an analysis testing if the behavior was the result of transitioning between academic tasks differing in preference. Task refusal did not occur in the demand condition of the functional analysis, indicating that the behavior was not maintained by escape from demands. Conversely, task refusal occurred solely in the second experimental analysis when transitioning from a high-preferred to a low-preferred academic task. In this case, the context of terminating a preferred academic task and transitioning to a less preferred academic task was aversive but not the demand itself. In addition, when an embedded break condition was compared to a no break condition in a multielement design, task refusal was reduced to zero levels.     

Total spin in the density matrix renormalization group algorithm

A new density matrix renormalization group (DMRG) algorithm is presented which conserves the total spin. This is the first time that standard DMRG is extended to exploit fully the symmetries of the Hamiltonian. The obtained general procedure works for any operator, even operators that do not commute with the Hamiltonian. The new method gives substantial improvements over the standard DMRG.     

Catching up with wonderful women: The women‐are‐wonderful effect is smaller in more gender egalitarian societies

Inequalities between men and women are common and well‐documented. Objective indexes show that men are better positioned than women in societal hierarchies—there is no single country in the world without a gender gap. In contrast, researchers have found that the women‐are‐wonderful effect—that women are evaluated more positively than men overall—is also common. Cross‐cultural studies on gender equality reveal that the more gender egalitarian the society is, the less prevalent explicit gender stereotypes are. Yet, because self‐reported gender stereotypes may differ from implicit attitudes towards each gender, we reanalysed data collected across 44 cultures, and (a) confirmed that societal gender egalitarianism reduces the women‐are‐wonderful effect when it is measured more implicitly (i.e. rating the personality of men and women presented in images) and (b) documented that the social perception of men benefits more from gender egalitarianism than that of women.     

Reasoning Is for Arguing: Understanding the Successes and Failures of Deliberation

Theoreticians of deliberative democracy have sometimes found it hard to relate to the seemingly contradictory experimental results produced by psychologists and political scientists. We suggest that this problem may be alleviated by inserting a layer of psychological theory between the empirical results and the normative political theory. In particular, we expose the argumentative theory of reasoning that makes the observed pattern of findings more coherent. According to this theory, individual reasoning mechanisms work best when used to produce and evaluate arguments during a public deliberation. It predicts that when diverse opinions are discussed, group reasoning will outperform individual reasoning. It also predicts that individuals have a strong confirmation bias. When people reason either alone or with like‐minded peers, this confirmation bias leads them to reinforce their initial attitudes, explaining individual and group polarization. We suggest that the failures of reasoning are most likely to be remedied at the collective than at the individual level.     

Cultural illiteracy and the Internet.

The Internet has created different expectations regarding its possibilities as a tool for including groups that have heretofore been excluded from the modern world. But mere access to information does not necessarily imply correct and effective use of it. Despite the great increase in Internet access in previously excluded areas, expectations of inclusion have not been fulfilled. Research suggests that the effectiveness of Internet use varies among cultures, but all such studies analyze countries as a whole with no further breakdown. Yet it is known that within a given country there co-exist subcultures that differ both in language and social context. This paper presents a study that shows the correlation between different social subcultures and their Internet knowledge.     

Decision Making in Social Context in Patients with Suicide Attempt History

Decision making has been found to be altered in suicide attempters, but little is known of their performance in social contexts. Twenty‐seven depressed suicide attempters (DSA), 25 nonsuicidal depressed patients (DP), and 60 healthy participants (HC) were evaluated by a decision‐making task in social context . Results indicated DSA and DP obtained lower gains and invested more money with angry partners. DSA were found to invest less money than DP and HC with happy partners. DSA showed insensitivity toward rewards/punishment contingency, and they did not use the socioemotional stimuli to guide their decisions.
