移动窗口条件下阅读过程中字词识别特点的研究

采用“移动窗口”技术对中文阅读过程中的字词识别进形了初步的探讨。被试是８名大学生,阅读材料为８篇科学文章。结果发现,在移动窗口条件下,词的注视时间受词频、词中字数等词本身特性,词在理解文章中的重要性以及句子界限效应、文章难度等来自阅读理解的高级过程的影响。移动窗口技术可以在一定程度上较真实地探讨阅读中字词的连续加工过程。     

内观疗法对情绪体验影响的ERP研究

采用事件相关电位技术(ERPs)考察内观疗法对情绪体验影响的变化特点,以探明内观疗法是否引起情绪体验的变化。结果表明,内观组在400-1100ms平均波幅显著大于对照组,在内观组和对照组间,出现了显著的组间差异。由此得出结论,说明了内观疗法对情绪体验产生了影响,主要体现在情绪体验的深度与弥散性上。     

三种压力与创意自我效能感对创造力的影响

以216名初中二年级学生为被试,采用现场实验,探讨个体创意自我效能感在竞争、评价和时间三种压力情境下对创造力的影响。结果发现,三种压力对于总体创造力的影响不同;时间、评价压力分别提高了流畅性和新颖性,竞争压力既提高了流畅性又提高了新颖性,但三种压力情境都降低了变通性;创意自我效能感中间组的学生在压力情境下具有最好的变通表现,而效能感低分组表现最差。     

Main and interaction effects of metallic toxins on classroom behavior

This study investigated the relationships of metal levels and metal combinations to children's classroom behavior. Hair-metal concentrations of lead, arsenic, mercury, cadmium, and aluminum were determined in 80 randomly selected elementary-age children, who were also rated by their classroom teacher on the Walker Problem Behavior Identification Checklist (WPBIC). Parents were interviewed to control for confounding variables that may have affected behavioral development. Regression analysis indicated that the set of metals was significantly related to increased scores on four of the five WPBIC subscales and on the total scale, with lead being a major contributor to four of the six dependent measures. Metal combinations were significantly related to increased scores on the WPBIC subscales measuring acting-out, disturbed peer relations, and immaturity, and on the total scale. A continuing reexamination of metal poisoning concentrations is needed because metal levels and metal combinations previously thought harmless may be associated with nonadaptive classroom behavior.     

BOHM AND WHITEHEAD ON WHOLENESS, FREEDOM, CAUSALITY, AND TIME

Abstract. David Bohm's developing postmodern thought (combining precision and wholeness) is seen to contain two tendencies. One is a vision of "underlying wholeness," in which all causation is vertical, and the implicate-explicate relation is ubiquitous. This provides a possible solution to certain problems, but creates many others involving freedom, causation, and time. Second, many of Bohm's statements suggest that his deepest intuitions could be formulated without those problems in terms of the distinctions developed in Alfred North Whitehead's philosophy of "prehensive wholeness," in which the ubiquity of creativity would require a more restricted use of the implicate-explicate relation.     

Detecting true lies: police officers' ability to detect suspects' lies

Ninety-nine police officers, not identified in previous research as belonging to groups that are superior in lie detection, attempted to detect truths and lies told by suspects during their videotaped police interviews. Accuracy rates were higher than those typically found in deception research and reached levels similar to those obtained by specialized lie detectors in previous research. Accuracy was positively correlated with perceived experience in interviewing suspects and with mentioning cues to detecting deceit that relate to a suspect's story. Accuracy was negatively correlated with popular stereotypical cues such as gaze aversion and fidgeting. As in previous research, accuracy and confidence were not significantly correlated, but the level of confidence was dependent on whether officers judged actual truths or actual lies and on the method by which confidence was measured.     

The Meaning and Impact of Head and Neck Cancer: An Interpretative Phenomenological and Repertory Grid Analysis

This study explores the personal meaning of head and neck cancer for individuals, with particular reference to the impact on the self. It employs interpretative phenomenological and repertory grid analysis with 10 people, all of whom have undergone surgical treatment for head and ceck cancer. Four themes emerged: namely, destruction of self, altered relations with the body, disenfranchised self, and conservation of self. Repertory grid analysis validated and enriched understanding of these findings. Participants described how head and neck cancer inflicted a fundamental attack on their sense of self. Nonetheless, participants were dynamic in their self-management and detailed an active process to retain a positive sense of self.     

Psychopathy,anxiety and malingering

Psychopathy is commonly measured as a low score on an Anxiety scale or as a high score on the MMPI Pd scale. The Pd scale, the Spielberger et al. Trait Anxiety scale and a short Achievement Motivation scale were administered to a random postal sample of 115 Australians. It was found that there was a high positive correlation between the Pd and Anxiety scales. This strongly supports Eysenck's theory that psychopaths are neurotic extraverts. A possible alternative explanation of the findings, however, is that the Pd scale may measure not psychopathy but malingering.     

Decoupling neural networks from reality: dissociative experiences in torture victims are reflected in abnormal brain waves in left frontal cortex

From a neuroscience perspective, little is known about the long-term effect of torture. Dissociative experiences and posttraumatic stress disorder are often the results of this experience. We examined psychological dissociation within a group of 23 torture victims and report its manifestations within neural networks in the human brain. In particular, we observed that dissociative experiences are associated with slow abnormal brain waves generated in left ventrolateral frontal cortex. Given that focal slow waves often result from depriving neural networks of major input, the present results may indicate decoupling of frontal affective processors from left cortical language areas. This interpretation is consistent with the fact that disturbed access to structured verbal memory concerning traumatic events is a core feature of the dissociative experience.
