The effect of performer gender,performer skill level,and opponent gender on self-confidence in a competitive situation

An equal number of male and female subjects (N=48), ranging in age from 17 to 26, were randomly assigned to compete in three competitive video games against a male or female opponent. All subjects were given bogus feedback that they had lost two out of three video games by a standard margin. Initial performance expectancies, as well as postcompetition expectancies, of all subjects were recorded. Initial performance expectancy scores recorded prior to competition were analyzed in a 2 (subject gender)×2 (opponent gender) analysis of covariance (ANCOVA) design with initial skill level on a preliminary game as the covariate. No significant gender differences in initial expectancy scores were found. A 2 (subject gender)×2 (opponent gender) ANCOVA design was utilized to analyze the postcompetition expectancy scores with initial performance expectancy as the covariate. The analysis revealed no significant differences. These findings did not support Corbin's (1981) data suggesting that females express significantly less self-confidence than males for future performance after competing against and losing to a superior opponent on a video task. Initial performance expectancies in the present study were significantly correlated (p.05) to skill level, indicating that performance expectancies may be more related to skill level than to gender. Thus, a realistic perception about one's initial skill level on a particular task may be the most salient determinant of performance expectancies.     

The development of executive functions and early mathematics: A dynamic relationship

Background. The relationship between executive functions and mathematical skills has been studied extensively, but results are inconclusive, and how this relationship evolves longitudinally is largely unknown. Aim. The aim was to investigate the factor structure of executive functions in inhibition, shifting, and updating; the longitudinal development of executive functions and mathematics; and the relation between them. Sample. A total of 211 children in grade 2 (7–8 years old) from 10 schools in the Netherlands. Method. Children were followed in grade 1 and 2 of primary education. Executive functions and mathematics were measured four times. The test battery contained multiple tasks for each executive function: Animal stroop, local global, and Simon task for inhibition; Animal Shifting, Trail Making Test in Colours, and Sorting Task for shifting; and Digit Span Backwards, Odd One Out, and Keep Track for updating. The factor structure of executive functions was assessed and relations with mathematics were investigated using growth modelling. Results. Confirmatory factor analysis (CFA) showed that inhibition and shifting could not be distinguished from each other. Updating was a separate factor, and its development was strongly related to mathematical development while inhibition and shifting did not predict mathematics in the presence of the updating factor. Conclusions. The strong relationship between updating and mathematics suggest that updating skills play a key role in the maths learning process. This makes updating a promising target for future intervention studies.     

On the origin of the understanding of time, speed, and distance interrelations

We examined 18- and 24-month-old infants' sensitivity to the functional relationships between time, speed, and distance. The task included a train moving first visibly and then into a tunnel. The movement of the train was always accompanied by a train-characteristic sound signalling the travel duration. After the train concluded its travel, infants were requested to search for it in two possible locations inside the tunnel. Infants' reaching and head turn behavior indicated that 24-month-olds were sensitive to time-speed-distance interrelations, while 18-month-olds showed no such understanding. Reducing occlusion duration (by shortening the tunnel's length) revealed an increase in 18-month-olds' reaching and anticipatory head turns. Results are discussed in terms of the developmental course of the understanding of time-speed-distance interrelations and the strength of infants' representations.     

Contextual fear conditioning predicts subsequent avoidance behaviour in a virtual reality environment

Avoidance behaviour is a crucial component of fear and is importantly involved in the maintenance of anxiety disorders. Presumably, fear conditioning leads to avoidance of the feared object or context. A virtual reality contextual fear conditioning paradigm was used to investigate the association between explicit conditioning effects and subsequent avoidance behaviour. Mild electric shocks were administered in one context (anxiety context), but never in a second context (safety context). Subsequent avoidance behaviour was assessed by asking participants to choose two out of three contexts (a neutral context was added) to visit again. Participants avoided the anxiety context, but did not prefer the safety over the neutral context. Participants with substantial conditioning effects, as reflected in differential valence, arousal and anxiety ratings, avoided the anxiety context but not the safety context. In sum, we demonstrated an association between context conditioning effects on an explicit level and later avoidance behaviour.     

《文化演化与宗教》

社会学家贝拉(Robert Bellah)在其颇具影响力"宗教演化"的文章中,根据广泛的人类经验提出了一个检验文化和宗教互动的模式。贝拉在其雄心勃勃的计划中还是保持相当的谦虚,他警觉到其所用的例证源于历史文献,而模式本身则不是历史。模式是"一种思考的工具":一个用来指导思考的理论性框架,而非基于田野调查的经验性描述。在我们下面的讨论中,我们将使用贝拉的"思考工具"的基本模式,将包括来自贝拉本人和其他宗教学者研究中的一些修正和补充的内容。

To Preserve,Protect, and Defend: Masculine Honor Beliefs and Perceptions of the 2016 Presidential Candidates

We investigated the relationship between masculine honor beliefs and perceptions of the candidates vying for the presidency. Consistent with hypotheses, we found that higher levels of masculine honor beliefs were associated with more positive perceptions of Donald Trump and with more negative perceptions of Hillary Clinton. Furthermore, our results indicate that higher levels of masculine honor beliefs were associated with clear preferences for Donald Trump. Thus, our data, collected immediately prior to the election likely reflect the beliefs and perceptions that individuals took with them to the polls and help to explain the decisions that voters made on Election Day.     

REMEDIATION OF ALEXIA: A CASE STUDY

This article describes the results of a remedial program provided to a subject who had incurred aphasia and alexia as a result of a series of strokes. The subject was pretested individually on a battery of tests and provided a specific type of remediation by a trained tutor. Posttests were administered to determine the effects of the instructional methods. Substantial gains were noted in language and auditory comprehension with a lesser gain in word recognition. Scores on other tests remained unchanged and the subject continued to make errors indicative of alexia. The results suggest that further research of the remedial methods over a longer period of time is needed.
