平面几何解题过程中加工水平对迁移的影响

通过实验研究,平面几何靶题难度以及解题者对靶题与源题之间存在着共性关系的加工水平对解题迁移的影响得到了验证。结果表明,解题者对具有内在联系的先后问题之间共性关系的加工水平是影响解题迁移的因素之一;靶题的难度太大或太小,将导致解题者对先后问题之间共性关系的加工作用失败而出现地板效应和天花板效应,且靶题难度与加工水平在影响解题迁移时有交互作用。

Does diversity in team members’ agreeableness benefit creative teams?

Although deep-level diversity among team members are often discussed as important catalysts of team creativity, little is currently understood about the impact of diversity in team members’ personality on team creativity and team satisfaction. We propose that diversity in team members’ agreeableness would reduce the effectiveness of creative teams through its impact on team conflict experienced. To test our hypotheses, we recruited 93 student teams to participate in a laboratory study where each member had their personality traits assessed before engaging in a team creativity task. We found that diversity in team members’ agreeableness was positively associated with team task conflict experienced which, in turn, was negatively associated with team creativity. Additionally, we found that diversity in team members’ agreeableness was positively associated with team relationship conflict, which, in turn, was negatively associated with team satisfaction. Implications and future directions are discussed.     

The temporal evolution of pre-stimulus slow cortical potentials is associated with an upcoming stimulus’ access to visual consciousness

Slow cortical potentials (SCPs) have been proposed to be essential for the formation of conscious experience. To examine their temporal characteristics, we recorded electroencephalography during a visual backward-masking task, which required participants to localize the missing part of a target stimulus. A subsequent confidence rating was used as a proxy for the target’s access to consciousness. Event-related potentials (ERPs) of all correct trials were determined relative to a brief period immediately before the target and then compared among consciousness levels. In an interval ranging from 2 s prior to target presentation up to this period, a negative relationship between slowly fluctuating ERP values and the level of consciousness became evident. After target presentation, high conscious awareness was characterized by an enhanced visual awareness negativity, an increased P3 component, and associated positive SCPs. Together, these findings add new evidence to the proposed role of SCPs in the emergence of visual consciousness.     

记叙文阅读中主人公转换对情境模型更新的影响

应用探测任务范式和事件分割范式,以反应时、正确率、均字阅读时间等为指标,探讨主人公转换在记叙文情境模型更新中的作用。结果显示：（1）在主人公转换与事件转换一致时,主人公转换条件下的认知加工更加困难,表现为较长的反应时和均字阅读时间,以及较低的正确率和较高的分割概率。（2）在主人公转换与事件转换不一致条件下,主人公转换对反应时和均字阅读时间的影响显著降低,而分割概率与无转换条件无差异。这表明,事件是记叙文情境模型的核心;主人公维度仅在代表事件转换的条件下,才能引起情境模型的更新。     

Can animation compensate for temporal processing difficulties in deaf people?

This article addresses the issue of animation as an aid for temporal processing difficulties in deaf people learning the Highway Code. A decision-making task involving static or animated road situations was performed by 21 deaf and 24 hearing participants. They were confronted with four types of driving situations (overtaking, negotiating roundabouts, highways, and intersections) and had to decide whether or not to proceed. Participants were presented with two different formats (static vs. animated) and two levels of difficulty (simple vs. complex). Results showed that deaf participants had poorer performances in the static condition than hearing participants. Performance was better in the animated condition than in the static condition, especially in deaf participants. The benefits of animation were greater in complex situations for all participants. Decisions made on dynamic road situations were facilitated by the presence of spatiotemporal dimensions. These proved helpful to deaf candidates who have difficulties in this particular area.     

催眠诱导下电击性厌恶试治同性恋3例

用催眠诱导情景下的电击厌恶试治同性恋３例均获成功。认为同性恋是情绪体验记忆的结果。单纯的认知治疗不可以消除情绪记,而单纯的行为治疗仅可消除对同性的性欲却无法重建对异性的性欲。认为要根治同性弯需用对异性的性欲代替对同性的性欲。催眠诱导情景下的电击厌恶既可消除对同性的性体验,又可建立对异性的性体验。     

The physiology of motor delusions in anosognosia for hemiplegia: Implications for current models of motor awareness

Right brain damaged patients sometimes deny that their left arm is paralysed or even claim to have just moved it. This condition is known as anosognosia for hemiplegia (AHP). Here, we used fMRI to study patients with and without AHP during the execution of a motor task. We found that the delusional belief of having moved was preceded by brain activation of the cortical regions that are implicated in motor control in the left intact hemisphere and in the spared motor regions of the right hemisphere; patients without anosognosia did not present with the same degree of activation. We conclude that the false belief of movement is associated with a combination of strategically placed brain lesions and the preceding residual neural activity of the fronto-parietal motor network. These findings provide evidence that the activity of motor cortices contributes to our beliefs about the state of our motor system.     

Rimes are not necessarily favored by prereaders: evidence from meta- and epilinguistic phonological tasks

This article explores young children's facility in phonological awareness tasks requiring either the detection or the articulation of head, coda, onset, and rime subsyllabic units shared in word pairs. Data are reported from 70 nonreading children and 21 precocious readers attending preschools. Prereading children were able to articulate shared heads, codas, and onsets, although rimes rarely were articulated. Precocious readers were able to articulate shared rimes, but articulation performance was still most accurate for onsets and codas. Rimes and heads were equally accessible in the detection task and were identified more often than onsets and codas (nonreaders) and codas (readers). It is concluded that the articulation advantage for nonrime units cannot simply reflect early reading instruction. This disjoint pattern of phonological awareness in detection and production tasks does not support Goswami's phonological status hypothesis. Results may instead reflect quite distinct influences on epilinguistic and metalinguistic phonological development.     

Emergent literacy skills and training time uniquely predict variability in responses to phonemic awareness training in disadvantaged kindergartners

The factors that predicted variability in responses to phonemic awareness training were investigated in kindergartners who live in poverty. Treatment children (n=42) received both analytic and synthetic phonemic awareness computer-assisted instruction, while controls (n=34) received no special training. Mean age of participants was approximately 5 years 7 months. Pretests included initial phonemic awareness, letter knowledge, word-level reading, invented spelling, vocabulary knowledge, and print concepts. Spelling skills emerged as the best consistent predictor of variability in phonemic awareness in response to instruction. We propose that relations between phonemic awareness and spelling skills are bidirectional: Spelling influenced growth in phonemic awareness and phonemic awareness contributed to growth in spelling skills. The amount of exposure that children had to the treatment intervention contributed uniquely to individual differences in posttest levels of phonemic awareness and spelling.
