大脑两半球的协同活动:右半球切除十四年后某些高级机能的观察

本文介绍了一癫痫病人切除右半球14年后大脑工作的情况。神经心理学检查表明:病人在非语言形式如线条、抽象图形的感知、认知和空间关系上遭到一定程度的破坏,但对颜色、音乐、具体人物和环境的认知和空间关系上没有明显障碍。左半球代偿了右半球部分功能,病人能胜任一般工作,并愉快地过着正常生活。     

Multinomial processing tree models: An implementation

Multinomial processing tree (MPT) models have been widely used by researchers in cognitive psychology. This paper introduces MBT.EXE, a computer program that makes MPT easy to use for researchers. MBT.EXE implements the statistical theory developed by Hu and Batchelder (1994). This user-friendly software can be used to construct MPT models and conduct statistical inferences, including point and interval estimation, hypothesis testing, and goodness of fit. Furthermore, this program can be used to examine the robustness of MPT models. Algorithms for parameter estimation, hypothesis testing, and Monte Carlo simulation are presented.     

Effects of imagining eating favorable and unfavorable foods on gastric motility indexed by electrogastrographic (EGG) activities

The purpose of this study was to investigate the effects of imagining favorable or unfavorable foods on the amplitude of EGG recordings. 40 subjects were assigned to Favorable food and Unfavorable food groups in which they were asked to imagine eating a list of favorable foods or unfavorable foods. Subjects sat in a chair for 16 min, of baseline measurement prior to the 16 min. of food imagining. Electrogastrographic (EGG) activities were recorded continuously throughout. Using Fast Fourier Transform analysis, the spectral power of EGG activity of 3 cycles per minute (cpm) was calculated, and the ratios of EGG 3 cpm spectral power for the period of food imagining and baseline were obtained. The EGG amplitude at 3 cpm during imagining eating a list of unfavorable food was significantly lower than that of the baseline period and the EGG ratio between the food-imagining and baseline periods was significantly lower in the Unfavorable group than in the Favorable food group. It appears that imagining eating unfavorable food significantly inhibited gastric motility as indexed by decreased power of EGG activities at 3 cpm.     

Sleep facilitates consolidation of emotional declarative memory

Both sleep and emotion are known to modulate processes of memory consolidation, yet their interaction is poorly understood. We examined the influence of sleep on consolidation of emotionally arousing and neutral declarative memory. Subjects completed an initial study session involving arousing and neutral pictures, either in the evening or in the morning. Twelve hours later, after sleeping or staying awake, subjects performed a recognition test requiring them to discriminate between these original pictures and novel pictures by responding "remember,"know" (familiar), or "new." Selective sleep effects were observed for consolidation of emotional memory: Recognition accuracy for know judgments of arousing stimuli improved by 42% after sleep relative to wake, and recognition bias for remember judgments of these stimuli increased by 58% after sleep relative to wake (resulting in more conservative responding). These findings hold important implications for understanding of human memory processing, suggesting that the facilitation of memory for emotionally salient information may preferentially develop during sleep.     

Double challenges: How working from home affects dual-earner couples’ work-family experiences

Against the backdrop of COVID-19 pandemic, we draw on family systems theory to elucidate how daily work-from-home status (WFH) affects both members in dual-earner couples. We propose that the WFH exerts intra-individual and inter-individual influences on employees’ and their partners’ work task and family task completion and their subsequent reactions to their work and family experiences. We examined the hypothesized relationships with two daily survey studies on dual-earner couples conducted during the pandemic (i.e., 1,559 daily responses of 165 dual-earner couples from China in Study 1, and 773 daily responses of 57 dual-earner couples from South Korea in Study 2). The two studies provide converging results that working from home (vs. office) increased employees’ family task completion for both husbands and wives and that wives working from home (vs. office) decreased husbands’ family task completion. Further, in both studies, daily work task completion increased felt guilt toward family (for wives only) through increased work-family conflict, and daily family task completion increased psychological withdrawal from work through increased family-work conflict for both husbands and wives. Moreover, we found in Study 2 that on days when husbands had flexible work schedule, wives completed more work tasks when working from home (vs. office) and that on days when wives had inflexible work arrangement, husbands completed more family tasks when working from home (vs. office). Across the two studies, there were no clear gender-difference patterns in husbands’ and wives’ work and family experiences.     

The Role of Personal Centrality of Ingroup Victimhood in Intergroup Relations and Political Agenda in Northern Ireland

Even though the violent conflicts during the Troubles officially ended decades ago, the memories of violence and division between Catholics and Protestants linger in Northern Ireland. We argue that the personal centrality of collective victimhood, which is formed by the memory and perception of past and ongoing victimization, may play an important role in people's attitudes in postconflict societies. The current study investigated both the antecedents and outcomes of the personal centrality of ingroup victimhood in Northern Ireland and examined the vital role it plays in the aftermath of a violent intergroup conflict among Catholics and Protestants. The results demonstrated that ongoing experiences of victimization such as personal and group-level discrimination and memories of personal and close others' suffering are strongly related to people's personal centrality of ingroup victimhood. The centrality of ingroup victimhood, in turn, predicted various strategies for intergroup interaction and policy preferences such as collective action, support for nonviolence, and attitudes toward reunification of Ireland, which were moderated by group membership. The findings provide empirical evidence for the role of the centrality of ingroup victimhood as a link between experiences of victimization and intergroup interactions as well as policy preferences.     

论三段论推理过程中结论正确性的两种判断标准

人们进行三段论推理加工时是根据什么标准来判定推理结论的正确性的？实验结果支持下述观点：人们在进行三段论推理过程中,在判定推理结论的正误时,存在两种判定标准：一种是“形式标准”,另一种是“内容标准”;两种判定标准对于人们判定结论的正确性都有影响,哪个判定标准的影响力更大依赖于人们已掌握的知识结构。

推理结论正确性判定标准再探

本文试图探求人们在进行三段论推理加工时是否存在形式和内容双重标准。由既掌握形式逻辑推理规则又知道构成推理题的两个前提是否正确的被试所进行的推理结果支持下述观点：人们在进行三段论推理过程中,在判定推理结论的正误时,存在着与试题结构相应的两种内在的判定标准,即“形式标准”和“内容标准”。
