自我概念威胁以及与重要他人的比较共同削弱自我面孔优势效应

内隐积极联想理论(implicit positive association, IPA)认为自我面孔识别以及与之伴随的自我意识激发了自我概念的积极属性, 促进了对自我面孔的识别优势, 因此通过自我概念威胁可以削弱自我面孔识别的优势效应。本研究旨在探讨自我概念威胁以及与重要他人的比较对自我面孔优势效应的共同影响。实验一为自我-朋友对比实验, 10对同性好友(20名被试)在接受完自我概念威胁启动或者非威胁性启动后对自我面孔和朋友面孔进行朝向的判断, 结果发现非威胁性启动后, 自我面孔的优势效应依然存在, 而在自我概念威胁启动后, 自我面孔优势效应消失。实验二为自我-陌生人对比实验, 另外20名被试在接受完自我概念威胁启动或者非威胁性启动后, 对自我面孔和陌生人面孔进行朝向的判断, 结果发现, 无论是自我概念威胁启动还是非威胁性启动后, 自我面孔识别优势效应都依然存在。两个实验的结果均主要体现在用左手进行反应的时候。结果表明：自我概念威胁以及与重要他人的比较共同削弱自我面孔优势效应; 而左手效应的发生似乎表明了大脑右半球对自我面孔识别的主导和调节作用。     

A PSYCHO-PHILOSOPHICAL ANALYSIS OF FOULS AND INTENTIONS IN CONTACT SPORTS

This paper examines the notion of fouls in sports. In the first part of the paper, we examine some actual distinctions and classifications between different kinds of fouls. In the second part we examine the significance, validity, and justification of these classifications from a normative perspective.The term ‘foul’ evokes negative connotation; some would say—negative normative connotations. Conventional wisdom suggests that typically to commit fouls is, by definition, to go against the rules or principles of the contest. Since sport contests are constitutive activities—this means that to foul is to go against the essence of the contest. In other words, to commit fouls seems not to play the game; it seems unsporting. Consider the following typical example: in a premiership match in 2014 Hull’s forward Nikica Jelavic spun around Company and had a clear path to the goal. Manchester City’s defender Vincent Kompany then held him back. Although immediately ejected from the game, it is noteworthy that Kompany was later banned from one match, rather than the usual three match suspension, because the foul was not violent or dangerous in any way. Nevertheless, the example shows that some fouls are considered unsporting even though they do not involve violent or dangerous play. If a player gets past her opponent and finds herself in front of the goal, and then her opponent hugs her forcefully from behind, then such a foul falls outside the bounds of play. It amounts to a refusal to accept the rules of the games. We explore this issue from both a philosophical and a psychological perspective. The first half of the paper shows how actual distinctions between fouls depend on awarding a normative role to intentions. In the second part, a difficulty regarding the possibility that intentions play this role is presented, and a solution is proposed. It will emerge that some fouls are a legitimate part of the game. According to the proposed view, some actions that are forbidden by the official rules of football are illegitimate when performed with intention of a certain kind. Specifically, we will argue that it is legitimate for a player to play so as to take the risk of fouling, so long as fouling is not her intention. When fouls are committed with such a state of mind, they are a part of the game. Furthermore, whereas intention is necessary for illegitimate fouls, it is not sufficient. We will argue briefly that there are also legitimate intended fouls, since some deals or exchanges—fouls in return to penalties—are considered an integral part of the game, and that this view of (some) fouls is legitimate.     

Interfaith Dialogue

The modern ecumenical movement initially sprang from the missionary movement. This led to considerable struggle within the ecumenical movement over embracing interfaith dialogue as a main focus of its ministry. This focus was eventually accepted, and since then the ecumenical movement has done much to promote interfaith relations at the local, national, and global level; to struggle with the theological issues such dialogue presents for the Christian faith; and to collaborate with other religions to reflect on common issues faced by the global community. Current Dialogue has played a major role in promoting the dialogue concern.     

This is Not About Sex? A Discussion of the Understanding of Love and Grace in Bernard of Clairvaux's and Martin Luther's Theologies

Abstract : This article engages the understanding of love and grace in Bernard's and Luther's theologies. Taking as a point of departure Anders Nygren's dichotomy of love in agape and eros, Wiberg Pedersen outlines some of the issues raised by Nygren's thesis. Arguing against Nygren's caricature of Bernard's theology, Wiberg Pedersen shows the similarities between Bernard's and Luther's understandings of love and grace, which lead her to hypothesize that Luther was inspired by Bernard in a theologia caritatis that is simultaneously a theologia cordis (creation and inspiration) and a theologia crucis (incarnation and justification), all led by grace.     

The Shape Bias is Affected by Differing Similarity Among Objects

Previous research has demonstrated that visual properties of objects can affect shape-based categorization in a novel-name extension task; however, we still do not know how a relationship between visual properties of objects affects judgments in a novel-name extension task. We examined effects of increased visual similarity among the target and test objects in a shape bias task in young children and adults. Experiment 1 assessed college students with sets of objects whose similarity between target and test objects was either low or high similarity. Adults preferred shape when the similarity among objects was minimized. Experiment 2 tested 24-month olds in their use of the shape bias using the Intermodal Preferential Looking Paradigm. Children showed a shape bias only with items whose similarity to each other was low. These findings suggest that the visual properties of objects affect shape bias performance.     

Supervisor Support in the Work Place: Legitimacy and Positive Affectivity

Abstract

The authors tested 3 hypotheses regarding supervisor support in the work place. The validation hypothesis predicts that when employees are supported by their coworkers and the larger organization, they also receive more support from their supervisors. The positive affectivity hypothesis predicts that employees with positive dispositions receive more supervisor support because they are more socially oriented and likable. The moderation hypothesis predicts a joint multiplicative effect between validation and positive affectivity. An assessment of the hypotheses among a sample of 1,882 hospital employees in Korea provided strong support for the validation and moderation hypotheses.     

Learning in context: linguistic and attentional constraints on children's color term learning

Three experiments investigated whether linguistic and/or attentional constraints might account for preschoolers' difficulties when learning color terms. Task structure and demands were equated across experiments, and both speed and degree of learning were compared. In Experiment 1, 3-year-olds who were matched on vocabulary score were taught new secondary color terms by corrective, semantic, or referential linguistic contrast. Corrective contrast produced more rapid and more extensive learning than did either semantic or referential contrast, supporting the hypothesis that targeted linguistic feedback facilitates learning. Experiment 2 replicated and extended the first experiment with Italian children and found cross-cultural differences in the amount learned about colors named differently in the two languages. In Experiment 3, some of the children were introduced to the new terms within a context of enhanced perceptual salience. These children learned as fast and performed as accurately as those given corrective linguistic feedback in Experiment 1.     

An analysis of reinforcement history effects

Four pigeons were exposed to two tandem variable-interval differential-reinforcement-of-low-rate schedules under different stimulus conditions. The values of the tandem schedules were adjusted so that reinforcement rates in one stimulus condition were higher than those in the other, even though response rates in the two conditions were nearly identical. Following this, a fixed-interval schedule of either shorter or longer values than, or equal to the baseline schedule, was introduced in the two stimulus conditions respectively. Response rates during those fixed-interval schedules typically were higher in the presence of the stimuli previously correlated with the lower reinforcement rates than were those in the presence of the stimuli previously correlated with the higher reinforcement rates. Such effects of the reinforcement history were most prominent when the value of the fixed-interval schedule was shorter. The results are consistent with both incentive contrast and response strength conceptualizations of related effects. They also suggest methods for disentangling the effects of reinforcement rate on subsequent responding, from the response rate with which it is confounded in many conventional schedules of reinforcement.     

Flexible contrast gain control in the right hemisphere

This study investigates whether the right hemisphere has more flexible contrast gain control settings for the identification of spatial frequency. Right-handed participants identified 1 and 9 cycles per degree sinusoidal gratings presented either to the left visual field-right hemisphere (LVF-RH) or the right visual field-left hemisphere (RVF-LH). When luminance contrast was randomized across a wide range (20-60%), performance gradually improved with contrast in the LVF-RH. Conversely, performance in the RVF-LH was disrupted and saturated for 20 and 60% of contrast, respectively, leading to a LVF-RH advantage for these contrast levels. When contrast was blocked or randomized for a smaller range (30-50%), the LVF-RH advantage was diminished. Flexible contrast gain control is needed when contrast is randomized across a wide range, but not when it is blocked or randomized across a smaller range. The results therefore suggest that the right hemisphere is able to process spatial frequency information across a wider range of contrast levels than is the left hemisphere.
