公安民警的创伤后应激症状对执行功能的影响—基于Stroop范式的探究

公安民警常常身临应激和危险情境中,是创伤事件的易感人群,但其创伤后应激症状对执行功能的影响研究尚且缺乏。已有研究发现,具有创伤后应激症状的个体的执行功能存在缺陷,表现在对冲突信息的抑制能力受损以及对创伤相关信息的注意偏向和情绪唤起。本研究以公安民警为实验组被试,据其创伤后应激症状分为高低两组,在校大学生为对照组被试,采用Stroop范式探究创伤后应激症状对公安民警“冷”、“热”执行功能的影响。结果表明,具有创伤后应激症状的公安民警在“冷”、“热”执行功能上不存在缺陷,但仍在一定程度上受到创伤后应激症状的影响。启示对具有创伤后应激症状的公安民警进行干预时,应关注其症状的严重程度,在“热”执行功能上寻求更有效的干预方式。     

Contextual control of equivalence-based transformation of functions

The transformation of functions refers to the untrained acquisition of stimulus functions among members of stimulus equivalence classes or relational frames. Although it is widely assumed that contextual control over the transformation of fuctions must exist, this has not yet been conclusively demonstrated in laboratory studies. Four experiments are reported in which (a) stimulus equivalence classes were established, (b) a conditional stimulus function was trained for one member of each of the classes, and (c) multiple-exemplar procedures were used to train and test for contextual control over the transformation of the stimulus function within the classes and to assess whether it generalized to new equivalence classes. Although a significant amount of training was required, the procedures ultimately resulted in the contextual control of function transformation for 9 of 10 participants and generalized contextual control for 4 of 5 participants.     

Effects of right and left hemisphere damage on performance of the "Right Hemisphere Communication Battery"

A Hebrew adaptation of Gardner and Brownell's (1986) "Right Hemisphere Communication Battery" (HRHCB) was administered to 27 right brain-damaged (RBD) patients, 31 left brain-damaged (LBD) patients, and 21 age-matched normal controls. Both patient groups showed deficits relative to controls and overall there was no difference between the two patient groups. A factor analysis of patients' scores on the HRHCB yielded two interpretable factors, a verbal and a nonverbal one. These factors were not lateralized. Performance of patients on the HRHCB correlated significantly and positively with performance on most tests of basic language functions, measured with a Hebrew adaptation of the "Western Aphasia Battery" (HWAB) and with other cognitive functions measured with standardized neuropsychological tests. There were stronger correlations of HRHCB with subtests of the HWAB in LBD patients and with nonlanguage cognitive tests in RBD patients. In the LBD group, HRHCB subtests' scores correlated negatively with lesion extent in frontal and temporal perisylvian regions. Such localization was not observed in RBD patients. The results argue against selective right hemisphere (RH) involvement in the RHCB, alleged to measure pragmatic aspects of language use, and show, instead, bilateral involvement. The results also argue against a modular organization of these functions of language use, especially in the RH.     

The Role of Referent and Expert Power in Mutual Help

This study explored the roles of referent power (i.e., influence based on sense of identification) and expert power (i.e., influence based on knowledge and expertise) in Schizophrenics Anonymous (SA), a mutual-help group for persons experiencing a schizophrenia-related illness. The study describes SA participants' experience of referent and expert power with SA members, SA leaders, and with mental health professionals. It also examines whether or not referent and expert power ascribed to fellow SA participants predicts the perceived helpfulness of the group. One hundred fifty-six SA participants were surveyed. Participants reported experiencing higher levels of referent power with fellow SA members and leaders than with mental health professionals. They reported higher levels of expert power for mental health professionals and SA leaders than for SA members. The respondents' ratings of their SA group's helpfulness was significantly correlated with ratings of referent and expert power. Although expert power was the best independent predictor of helpfulness, a significant interaction between referent and expert power indicated that when members reported high referent power, expert power was not related to helpfulness. These results are interpreted to suggest that there are multiple forms of social influence at work in mutual help.     

Auguste Comte on Positivism and Happiness

Auguste Comte (1798–1857) is the founder of a French school of thought that became famous for its encyclopaedic account of the sciences as well as for its exposition of what was designed as a way out of a state of intellectual and moral crisis. This essay demonstrates that there is a linkage between the diagnosis of crisis and the pursuit of happiness in Comte's foundation of positivism. It begins by distinguishing Comte's notion of positivism from that of a value-free science. In analysing Comte's peculiar usage of the term happiness, the essay shows that happiness is understood as the result of the convergence (consensus) of three components: a scientific conception of the world, the feelings of love and veneration, and a wisely ordered activity. The essay then demonstrates that the first of these components is of primary importance inasmuch as it is to frame a new horizon within which man is expected to return to a healthy state of mind, to reshape both his hopes and activities, and to discover his own participation in a supreme order acting through the laws of nature as well as through those of the civilization in which he lives. Conveying this new horizon to citizens of a lasting Republic is the sacred mission of sociology. The essay concludes by pointing out that Comte's conception of happiness can be assessed as unifying some main qualities of life as they are classified in Ruut Veenhoven's fourfold matrix.     

Establishing derived requesting skills in adults with severe developmental disabilities

This project examined whether a history of reinforced relational responding would result in derived requesting skills in 3 adults with disabilities. Participants were first taught to request preferred items using pictures; they were then taught conditional discriminations between pictures and their dictated names and between dictated names and their corresponding text. Finally, requests for preferred items using corresponding text were evaluated. All 3 participants demonstrated derived requesting skills.     

Age changes in the missing-letter effect revisited

When participants search for a target letter while reading, they make more omissions if the target letter is embedded in frequent function words than in less frequent content words. Reflecting developmental changes in component language and literacy skills, the size of this effect increases with age. With adults, the missing-letter effect is due to both word function and word frequency. With children, it is unclear whether the growing size of the missing-letter effect across development is due to a larger effect of word function, word frequency, or both because previous studies with children seeking to isolate the influence of word frequency and word function suffer from important methodological limitations. With these methodological limitations eliminated (Experiments 1 and 2), performance in a letter detection task was assessed for children in Grades 1, 2, 3, 4, and 7 as well as for undergraduate students. The results revealed that the influence of word function increases with age, whereas the effect of frequency is fairly stable across ages. Furthermore, normative predictability data collected in Experiment 3 revealed that third graders and undergraduate students were equally good at predicting function slots in a sentence.     

Psychometric Modeling of response speed and accuracy with mixed and conditional regression

Human performance in cognitive testing and experimental psychology is expressed in terms of response speed and accuracy. Data analysis is often limited to either speed or accuracy, and/or to crude summary measures like mean response time (RT) or the percentage correct responses. This paper proposes the use of mixed regression for the psychometric modeling of response speed and accuracy in testing and experiments. Mixed logistic regression of response accuracy extends logistic item response theory modeling to multidimensional models with covariates and interactions. Mixed linear regression of response time extends mixed ANOVA to unbalanced designs with covariates and heterogeneity of variance. Related to mixed regression is conditional regression, which requires no normality assumption, but is limited to unidimensional models. Mixed and conditional methods are both applied to an experimental study of mental rotation. Univariate and bivariate analyzes show how within-subject correlation between response and RT can be distinguished from between-subject correlation, and how latent traits can be detected, given careful item design or content analysis. It is concluded that both response and RT must be recorded in cognitive testing, and that mixed regression is a versatile method for analyzing test data.I am grateful to Rogier Donders for putting his data at my disposal.     

极权主义和政治现代性--读《极权主义的起源》

阿伦特的《极权主义的起源》是要揭示一种特殊的现代政治现象的起因和条件,探讨极权主义这个现代特有的现象的深层历史原因及其结构因素。正因为如此,她的许多观点和分析至今仍有重要的意义。极权主义是反犹主义、民族国家的衰落、种族主义、为扩张而扩张、资本和暴徒联盟结合在一起的产物。极权主义就是从根本上消灭人性,它反映了“我们世纪的危机”,揭示了西方文明及其价值体系的崩溃。
