THE ELUSIVENESS OF MASCULINITY: PRIMORDIAL VULNERABILITY,LACK, AND THE CHALLENGES OF MALE DEVELOPMENT

Reaching beyond the Oedipus prototype to address the unrepresentable vulnerability founded on the boy's infantile helplessness in contact with the mother's body, the author aims to identify the inherent tensions and enigmas of being male. He proposes that both the repudiation of femininity and the overvaluation of phallicity are unconsciously constructed to withstand the fundamental deficiency grounded in the asymmetry of the boy's prephallic relation with his primary object. This bodily based primordial vulnerability, marked by absence and lack, remains elusive—an unsymbolizable experience that provides the archaic matrix for adaptive and defensive phallicism, the oedipal complex, and genital progression. A clinical vignette is presented to illustrate these concepts.     

Aiming at the good

This paper shows how we can plausibly extend the guise of the good thesis in a way that avoids intellectualist challenge, allows animals to be included, and is consistent with the possibility of performing action under the cognition of their badness. The paper also presents some independent arguments for the plausibility of this interpretation of the thesis. To this aim, a teleological conception of practical attitudes as well as a cognitivist account of arational desires is offered.     

计算难度和知识背景对消费者百分数基数忽略的影响

在选择促销品时,消费者经常会出现百分数基数忽略错误,即价值判断时只基于百分数大小而忽略基数。本研究以150名大学生为被试,考察计算难度和知识背景对百分数基数忽略的影响。结果表明:仅了解百分数基数忽略现象的消费者无论计算难度高低均会出现百分数基数忽略错误;而了解促销计算原理的消费者在高难度下会出现这种错误,在低难度下则不会,且了解促销原理有助于减轻消费者在高难度下出现该错误的倾向。     

结构方程模型常用拟合指数检验的实质

拟合指数检验是评价结构方程模型(SEM)的重要环节。从协方差结构分析的角度将SEM与传统的回归模型比较,容易理解为什么SEM需要拟合指数。揭示了目前几种流行的拟合指数检验的实质:基于卡方的绝对拟合指数(如RMSEA)检验的实质是重新设定卡方检验的显著性水平(不同于通常的.05),相对拟合指数(如NNFI和CFI)检验的实质是基于虚模型设定均方(卡方与自由度之比)降低到的比例;在NNFI大于临界值后,报告和检验CFI是不必要的。根据研究结果提出了一些方便实用的拟合检验建议。     

Baseline Response Levels are a Nuisance in Infant Contingency Learning

The impact of differences in level of baseline responding on contingency learning in the first year was examined by considering the response acquisition of infants classified into baseline response quartiles. Whereas the three lower baseline groups showed the predicted increment in responding to a contingency, the highest baseline responders did not. Instead, they responded less in the contingency period relative to baseline. In extinction, the four baseline quartile groups failed to differ. The findings are considered in the context of the law of initial value, and some potential reasons for the effect of baseline responding on contingency learning are discussed. These studies show that variability in baseline responding may compromise our understanding of contingency detection especially for infants with high baseline response levels.

The influence of motivational and emotional factors in mathematical learning in secondary education

IntroductionWhile motivation has, for decades, been investigated as a key component of academic learning and performance, academic emotions have often been left out of the scope of investigation. According to several researchers, mathematics learning seems to be particularly affected by students’ emotions.ObjectiveThis paper is aimed at characterizing the emotions and motivation of eighth grade students in a mathematical setting and highlighting the cluster of emotions–activity emotions vs outcome emotions–which best predict math value, math self-concept, behavioral engagement and math performance.MethodData were collected through questionnaires from 115 students and analyzed through means comparisons and linear regressions.ResultsResults indicated that eighth grade students give a relatively high value to mathematics have a positive mathematics self-concept and are moderately engaged in mathematical tasks. Regression analysis showed that mathematics value and behavioral engagement are better explained by activity emotions while mathematics self-concept and performance are better predicted by outcome emotions.ConclusionThe implications of these findings in terms of educational practices are discussed at the end of this study.     

Trait worry is associated with difficulties in working memory updating

The current study investigated the effects of trait worry, a subcomponent of trait anxiety, on the process of updating information in working memory (WM). A leading theory on anxiety and executive functions, attentional control theory (ACT), states that anxiety is not related to WM updating in emotionally neutral situations. Previous research, however, has focused almost exclusively on WM span tasks that primarily emphasised storage, rather than the updating of WM representations. Moreover, few studies have directly examined the effects of trait worry. In this study, 116 subjects performed a WM updating task that required the memorisation of short lists of words and the within-trial removal of some of these items from WM. Results indicated that levels of trait worry were not related to word-span performance, but were related to performance on trials that required subjects to effectively update WM. Moreover, these effects were observed only for trait worry, not for levels of anxious arousal or comorbid levels of dysphoria. These results support the hypothesis that trait worry is related to WM updating performance and thereby extend ACT in new directions.     

刺激的视觉显著性和奖赏价值对眼跳的影响

本研究旨在探索刺激的视觉显著性和奖赏价值分别在协同和竞争的条件下对眼跳过程的影响。实验材料为成对的Gabor图案,要求被试选择具有更高奖赏价值的图案,并记录下其眼动过程。实验分为协同条件和竞争条件。结果发现,在不同实验条件下,奖赏价值对眼跳命中率和潜伏期均存在显著效应;视觉显著性的效应则在不同实验条件下出现了分离。刺激驱动过程和目标驱动过程对眼动行为的影响可能是互相区别的两种不同模式。
