Killing the straw man: Dennett and phenomenology

Can phenomenology contribute to the burgeoning science of consciousness? Dennett’s reply would probably be that it very much depends upon the type of phenomenology in question. In my paper I discuss the relation between Dennett’s heterophenomenology and the type of classical philosophical phenomenology that one can find in Husserl, Scheler and Merleau-Ponty. I will in particular be looking at Dennett’s criticism of classical phenomenology. How vulnerable is it to Dennett’s criticism, and how much of a challenge does his own alternative constitute? I will argue that there are some rather marked differences between these two approaches to consciousness, but as I also hope to make clear, Dennett’s own account of where the differences are located is off target and ultimately based on a somewhat flawed conception of what classical phenomenology amounts to.

Sex differences in parietal lobe morphology: relationship to mental rotation performance

Structural magnetic resonance imaging (MRI) studies of the human brain have reported evidence for sexual dimorphism. In addition to sex differences in overall cerebral volume, differences in the proportion of gray matter (GM) to white matter (WM) volume have been observed, particularly in the parietal lobe. To our knowledge there have been no studies examining the relationship between the sex differences in parietal lobe structure and function. The parietal lobe is thought to be involved in spatial ability, and particularly involved in mental rotation. The purpose of this study is to examine whether sex differences in parietal lobe structure are present, and if present to relate these differences to performance on the mental rotations test (MRT). We found that women had proportionately greater gray matter volume in the parietal lobe compared to men, and this morphologic difference was disadvantageous for women in terms of performance on the MRT. In contrast, we found that men compared to women had proportionately greater parietal lobe surface area, and this morphologic difference was associated with a performance advantage for men on mental rotation. These findings support the possibility that the sexual dimorphism in the structure of the parietal lobe is a neurobiological substrate for the sex difference in performance on the mental rotations test.     

Predicting OCB Role Definitions: Exchanges with the Organization and Psychological Attachment

Purpose  To investigate the relationship between trust in the organization and employees’ exchange beliefs (i.e., exchange ideology) and both psychological attachment and role definitions. Design/Methodology/Approach  A field study based on data from 204 line and supervisory employees examined the relationships between the predictors and work role boundaries. Two important mechanisms, psychological attachment (organizational commitment) and job satisfaction were examined as mediator and moderator, respectively, to the relationship between trust and exchange ideology and role definitions. Findings  Results indicate that both relation- and exchange-based variables predict enlarged roles (i.e., employees’ perceived organizational citizenship behaviors as in-role). Additionally, organizational commitment mediated the relationship between the predictor and the outcome. Job satisfaction moderated the relationship between trust and role definition. Implications  Work role boundaries are important in the contemporary workplace, where employees are oftentimes required to enlarge their behavioral set. We provide evidence for the importance of managing the relationship with the organization (through high levels of trust) and making sure employees construe their exchanges with the organization as more open. Such knowledge may help design interventions to increase employee trust, and select employees with favorable exchange ideologies. Originality/Value  This is one of the first studies examining both relationship- and exchange-based variables as predictors of role definitions, and clarifies possible mechanisms (mediation through psychological attachment) and the role of job satisfaction as moderator.     

An in-situ examination of the timing of information pick-up for interception by cricket batsmen of different skill levels

ObjectivesCricket batting is performed under demanding constraints, which requires rapid and accurate decision making for successful achievement of the skill goal. To understand how batsmen negotiate these constraints, the capability of highly skilled and low skilled cricket batsmen to utilise visual information prior to and during sections of ball flight to strike balls delivered by fast bowlers was examined.MethodSix highly skilled and six low skilled batsmen faced different types of balls delivered by three fast bowlers. Batsmen wore vision occlusion spectacles and were required to strike delivered balls, while their vision of the bowler's delivery action and ball flight was selectively occluded. Three vision conditions were randomly designed that included temporal occlusion at: (i) a point prior to ball release (providing only advance information), (ii) a point prior to ball bounce (providing advance and ball flight information) and (iii) no occlusion (where all advance, ball flight and bounce information were visible). Foot movements made forward or backward were assessed as a measure of ball length judgement, while the quality of bat–ball contact was assessed as a measure of interception.ResultsResults demonstrated the superior capability of highly skilled batsmen to utilise information prior to ball release to judge short ball length. Expert batsmen were better able to utilise ball flight information prior to and post-bounce to attain a superior number of bat–ball contacts.ConclusionsFindings demonstrate that the mechanism of experts to deal with task constraints when attempting to intercept a delivered ball is their capability to pick-up visual information to judge ball landing position.     

考试抄袭识别的心理测量学研究回顾

考试抄袭是最难识别的作弊方式。抄袭统计量（ACS）和人员拟合统计量（PFS）是识别抄袭的两类主要统计方法。ACS是根据被怀疑抄袭者与被抄袭者实际得分模式相似的概率来识别抄袭者。PFS 则把一个观察的项目得分模式与一定的测量模型相对比,来检验被试得分模式是否与测量模型预测的模式相吻合。其中,PFS由于在识别异常得分模式时存在一些干扰因素,所以对结果的解释存在多样性,应用较少。ACS是专门用于识别抄袭的统计方法,研究表明其识别率更高。目前ACS指标在美国的SAT和一些资格认证考试中已经得到广泛应用

Individuals lower in working memory capacity are particularly vulnerable to anxiety's disruptive effect on performance

Anxiety has a disruptive effect on performance in a number of domains. The purpose of this study was to determine whether individual differences in working memory (WM) capacity are related to an individual's susceptibility to anxiety's detrimental effect on performance. Fifty undergraduate students (28 females) were administered the State-Trait Anxiety Inventory (STAI) (Spielberger, Gorsuch, Lushene, Vagg, & Jacobs, 1983) to measure trait anxiety and the automated operation span task to measure WM capacity (Unsworth, Heitz, Schrock, & Engle, 2005). Then, they performed a highly demanding dual-task that consisted of a primary short-term memory task and a secondary tone-discrimination task that served as a measure of spare capacity. Anxiety and WM capacity interacted to affect performance on the auditory task so that those low in WM capacity were particularly vulnerable to anxiety's disruptive effect, whereas those high in WM capacity were buffered against anxiety's effect. These findings suggest that WM capacity may be an important factor in determining which individuals underperform on anxiety-provoking tests such as scholastic achievement tests.     

Friends’ Knowledge of Youth Internalizing and Externalizing Adjustment: Accuracy,Bias, and the Influences of Gender,Grade, Positive Friendship Quality,and Self-Disclosure

Some evidence suggests that close friends may be knowledgeable of youth’s psychological adjustment. However, friends are understudied as reporters of adjustment. The current study examines associations between self- and friend-reports of internalizing and externalizing adjustment in a community sample of fifth-, eighth-, and eleventh-grade youth. The study extends prior work by considering the degree to which friends’ reports of youth adjustment are accurate (i.e., predicted by youths’ actual adjustment) versus biased (i.e., predicted by the friend reporters’ own adjustment). Findings indicated stronger bias effects than accuracy effects, but the accuracy effects were significant for both internalizing and externalizing adjustment. Additionally, friends who perceived their relationships as high in positive quality, friends in relationships high in disclosure, and girls perceived youths’ internalizing symptoms most accurately. Knowledge of externalizing adjustment was not influenced by gender, grade, relationship quality, or self-disclosure. Findings suggest that friends could play an important role in prevention efforts.
