Crime and amnesia: A review

The present article reviews amnesia for criminal offenses. It discusses the organic disorders most likely to be implicated, and the nature and differentiation of psychogenic amnesia. With the exception of alcohol and drug intoxication, organic dysfunction is a rare (though important) cause of amnesia for crime. Likewise, fugue states may occasionally be triggered by an offence, but are a very rare cause of the amnesia claimed by offenders. Amnesia is most commonly seen in homicide cases, in which it is claimed by 25% to 45% of offenders, but it occurs also in other types of violent crime, and occasionally in nonviolent crime. It arises in states of extreme emotional arousal, in alcoholic intoxication, and in states of florid psychosis; and it is also associated with depressed mood. Various methods have been advocated for the differentiation of genuine amnesia from deliberate simulation: this distinction can be difficult, but it is noticeable that many amnesic subjects either have reported the crime themselves or have made no attempt to conceal it. The nature of the deficit in this type of amnesia, and its implications for assessment, are also discussed.     

Directionally different expectancy theory predictions of work motivation and job satisfaction

Conventionally, expectancy theory has utilized a multiplicative combination of expectancy and value scores in predicting both job behavior (work motivation and job performance) and job-related affect (job satisfaction). An extensive clinical literature, however, suggests that affect is a function of the discrepancy between expectancies and values. Hence, two hypotheses were advanced and tested in organizational settings: (1) that the multiplicative formulation (EV) will yield superior predictions of work motivation and job performance in comparison to the discrepancy model (E-V), (2) that the discrepancy model (E-V) will yield superior predictions of job satisfaction in comparison to the multiplicative model (EV). Results from three studies (of 399 engineers, 202 librarians, and 1,777 engineers) were highly supportive of both hypotheses.An early version of this paper was presented at the 10th Annual National Meeting of the American Institute for Decision Sciences, November 1, 1978, and an abbreviated write-up appeared in the AIDSProceedings. The author is greatly indebted to the following people: Susanne P. Wahba, for allowing the use of her data (Study Two); Gene Dalton and Paul Thompson, for their contribution to the research in Study One; and Joe Folkman for his help with the data analysis in Study Three. Financial support was provided in part by the Research Foundation of the City University of New York (RF10662).     

Psychological stages of careers in engineering: An expectancy theory taxonomy

Expectancy and value scores from 376 engineers were used to develop a taxonomy of nine psychological categories, these being differentially related to motivation and satisfaction. Static and longitudinal analyses (over 4 years) revealed significant relationships between age, prior category, and organizational reward practices, on the one hand, and the distribution and movement of respondents across categories, on the other. Results suggested a dynamic, three-stage psychological model of careers in engineering.     

主观声旁家族对汉语儿童汉字命名的影响

研究选取三年级、五年级和七年级学生,采用两个汉字命名实验,考察主观声旁家族对汉字命名的影响。实验一操纵主观声旁家族大小,发现三年级儿童没有表现出家族效应;五年级儿童表现出边缘显著的家族抑制效应,即对大家族的字命名更慢;七年级儿童表现出显著的家族抑制效应。实验二操纵了目标字是否有高频家族成员字（higher frequency neighbors,HFNs）这个变量,发现儿童普遍都表现出HFNs抑制效应,即对有高频家族成员字的目标字命名更慢。以上结果表明随着年级增长,主观声旁家族对儿童命名的影响逐渐增强,且高年级儿童已表现出家族抑制效应,这一表现与普遍出现的HFNs抑制效应有关。     

动作视频游戏对发展性阅读障碍者阅读技能的影响及其内在机制

发展性阅读障碍是一种在获得阅读技能方面的特殊困难, 这种障碍会严重影响个体的发展, 如何帮助发展性阅读障碍者改善其阅读技能是近年来研究的焦点。传统的干预方法主要针对发展性阅读障碍者的语音缺陷, 这类方法存在一些问题, 如费时费力、给阅读障碍者带来阅读压力等。近年来, 大部分研究表明通过趣味性的动作视频游戏训练可以显著地提高发展性阅读障碍者的阅读技能, 但是其背后的机制尚不明确。基于大细胞通路缺陷理论框架, 从视觉空间注意、注意跨通道转换、视觉运动加工等方面来梳理动作视频游戏与阅读之间的关系, 揭示了动作视频游戏训练对阅读效率影响的可能内在机制。未来的研究可以在大细胞通路缺陷理论的框架下, 深入分析动作视频游戏改善阅读的神经机制, 并尝试开发更适合发展性阅读障碍者的干预程序。     

发展性阅读障碍的听觉时间加工缺陷

发展性阅读障碍是指个体在智力正常并且不缺乏学校教育的情况下, 仍无法获得与年龄相匹配的阅读技能的一种学习障碍, 其缺陷的本质一直是研究者争论的焦点。大量研究显示, 阅读障碍者常表现出听觉时间加工损伤。在行为层面, 阅读障碍者难以辨别快速、连续呈现刺激的顺序以及刺激本身的动态时间特征。在神经层面, 阅读障碍者诱发的失匹配负波更弱且具有异常的神经同步加工。这些损伤同时存在于对言语和非言语刺激的加工中, 表明听觉时间加工缺陷非言语加工所特有。未来的研究还需阐明以下几个问题：1)阅读障碍的听觉时间加工缺陷发生在哪些时间窗口, 随年龄增长如何变化; 2)阅读障碍听觉时间加工缺陷在神经层面的时间进程是怎样的; 3)听觉时间加工缺陷是否为阅读障碍的核心缺陷。     

青少年早期同伴侵害的亚类别及其稳定性:个体定向的分析

以山东省济南市12所初中的2015名初一学生为被试,对其持续追踪至初二年级,采用自我报告法测查青少年的同伴侵害、受欺负和社交退缩,采用同伴提名法测查青少年的攻击行为。采用潜在剖面分析和潜在转变分析,探讨青少年早期同伴侵害的亚类别以及各亚类别中青少年受侵害身份的稳定性与发展变化。结果发现：（1）同伴侵害亚类别可以分为：未受侵害组、低受侵害组、中等受侵害组和高受侵害组四类,各亚类别间的异质性主要体现在受侵害程度上;（2）中等受侵害组和高受侵害组表现出高水平的攻击行为和社交退缩,且高受侵害组的社交退缩行为更多;（3）青少年早期个体的受侵害身份具有中到高水平的稳定性,同时也存在着一定的发展变化,主要表现为高受侵害组青少年倾向于向中等受侵害组转变,中等受侵害组青少年倾向于向低受侵害组转变。攻击行为是受侵害身份转变的重要预测因素。     

“己之所欲”还是“成人之美”？解释水平视角下个体赠送-接受礼物的偏好不对称性

解释水平理论被广泛应用于消费研究领域。本研究以解释水平理论为理论基础,采用情境问卷调查方法,通过5个实验探讨个体赠送与接受礼物时是否存在性别和角色偏好的不对称性。结果发现,一般情境下,受性别因素影响,男生偏好赠送和接受工具性礼物,女生偏好赠送和接受表达性礼物。但随着心理距离（社会距离和空间距离）的拉近,个体的解释水平降低,更关心他人的喜好和需求,赠送者会更基于接收者的偏好进行礼物选择。
