认知风格影响框架效应的ERP研究

采用ERP方法,考察了不同认知风格被试在决策过程中的框架效应。分析的脑电成分为N200和P300成分。结果发现：场依存者的反应时显著高于场独立者;场依存者诱发的N200和P300平均波幅均显著低于场独立者;大脑右半球的N200和P300平均波幅均显著高于左半球。这些结果表明,场独立者在决策过程中更具有理性,基本不受决策问题表述方式的影响,且该决策过程主要发生在大脑的右半球。     

Obesity as a variable affecting performance on the rod and frame test

Apparent similarities between S. Schachter's stimulus binding construct and H. A. Witkin's construct of psychological differentiation, specifically field dependence, have been noted in the literature. The present study examined field dependence on the rod-and-frame test among 20 obese and 42 average-weight subjects. Obese subjects were more field-dependent than were average-weight subjects. Women were slightly more field-dependent than were men. The author concluded that obese persons are more field-dependent and speculated that the constructs may be describing similar phenomena.     

Field dependence and attitude change: Source credibility can alter persuasion by affecting message-relevant thinking

The present study shows that for a personally relevant counterattitudinal issue, a highly credible source can alter persuasibility by increasing a subject's message-relevant thinking. Previous failures to show this effect were probably due to the highly thoughtful nature of typical research subjects, when confronted with involving issues. In the present study, field-dependent and field-independent subjects heard convincing or refutable counterattitudinal speeches given by sources of high or low credibility. Results indicated that subjects who are typically low in differentiation of stimuli (field-dependent subjects) showed differential persuasion to strong and weak arguments only when they were presented by a highly credible source. For subjects who are typically high in propensity to differentiate stimuli (field-independent subjects), the arguments were differentially persuasive for both high and low credible sources. These results are consistent with the hypothesis that increasing source credibility can enhance message-relevant thought for subjects who typically do not scrutinize message content.     

Effects of alcohol abuse and familial alcoholism on physical health in men and women

Detoxified alcoholic men (n = 76) and women (n = 72) and nonalcoholic control men (n = 50) and women (n = 51) were given a structured interview that assessed five categories of physical health: medical history, alcohol-related disorders, trauma history, drug use history, and, for females, female-related disorders. Approximately half the subjects in each group were family history positive for alcoholism. Significant differences between alcoholics and controls were found for all five categories; family history effects were significant for four of the five categories, and sex differences were present in two categories. The results indicate that (a) alcoholics suffer pervasive physical health difficulties, (b) a family history of alcoholism is predictive of health problems in both alcoholics and controls, (c) the effects of alcohol abuse and family history of alcoholism on health appear to be independent and additive, and (d) women may be more "illness prone" than men and exhibit an increased vulnerability to the adverse effects of alcoholism.     

Field dependence-independence (FDI) cognitive style: an analysis of attentional functioning

Previous research has indicated that field-dependent children display poorer performance than field-independent children in almost all academic subjects and cognitive tasks. However, the processes underlying this poorer performance remain unclear. The present study aimed to assess whether children with different FDI cognitive styles show differences in performance of tasks measuring aspects of attentional functioning. Specifically, 149 children aged 8 - 11 years were classified according to FDI cognitive style (field-dependent, intermediate, or field-independent), and to storage capacity (Digits Forward Test), verbal working memory (Digits Backward Test), capacity to focus, shift, and maintain attention (Digit Symbol Test), and capacity for sustained attention (Visual Search and Attention Test). Field-independent children displayed better performance than intermediate and field-dependent children on all tests except the Digits Forward Test. Theoretical and practical implications of these results are discussed.     

Motivation,heuristics, and the psychology of prediction

The present study was designed to test whether or not the use of representativeness and causality heuristics in decision-making results from insufficient or nonvigilant information processing rather than from an inherent deficiency in human information-processing ability. It was hypothesized that subjects who were distracted while making predictions (field-dependent subjects who were continuously aware of other subjects' performance in the experimental session) would fail to use the base rate to a greater extent than would nondistracted subjects (field-dependent subjects who were not aware of the other subjects' performance, and field-independent subjects). As predicted, when other subjects' performance was public, field-independent subjects conformed more to the base rate than did field-dependent subjects. In the private condition, however, the opposite pattern emerged. The results were discussed in terms of the drive theory of social facilitation and non-vigilant information processing.We would like to thank Matthew R. Marler for his comments on an earlier draft of this paper.     

Flexibility of information processing and the memory of field-independent and field-dependent learners

This study examined memory differences between 48 field-independent and 48 field-dependent learners, and it hypothesized that rigid information processing by field-dependent learners interferes with cue efficiency during memory recall. The field-independent and field-dependent learners were presented with paired associates in which the target recall words were homographs, and accompanying associates emphasized one of the homograph's two meanings. Homograph recall occurred under three conditions: (a) same cue recall, (b) different cue recall (emphasized other meaning of homograph), and (c) free recall. This study found memory differences favoring the field-independent learner and findings consistent with the rigid information processing hypothesis of field-dependent learners.     

Characteristics of the relapse situation of alcoholics treated with aversion conditioning

Recently, there has been considerable interest in applying the principles of learning theory and operant conditioning to the problems of alcoholism. One principle which may be of value is stimulus control. The principle of stimulus control would suggest that there should be some degree of similarity between the environmental circumstances in which alcoholics do their drinking and the situation where they take their first, post-treatment, drink. The principle of stimulus control also suggests that alcoholics treated with aversion therapy would tend to relapse under environmental conditions that were in some way different from their usual drinking environments.Whether we are able to observe a difference in drinking environments before and after treatment depends on whether we have selected the appropriate stimulus dimensions. The present author is in agreement with Lunde and Vogler (1970) who suggest that; types of liquor consumed; drinking associates; whether at home alone, with others or at a bar; are some of the important characteristics of an alcoholic's learning history. These stimulus conditions could be further simplified to location, type of beverage and social or non-social drinking.Since it is physically impossible to turn time backwards or to have observers follow patients everywhere they go, we must rely on self-reports of alcoholics about their drinking history. Although many clinicians have reservations about the veracity of alcoholics. Guze et al. (1963) report that 97 per cent of alcoholics in a prison population could be correctly diagnosed from their own self-report. Thus, it appears that at least when interviewed in the context of a research study where no contingencies are placed on their behavior, verbal or otherwise, self-report by alcoholics can indeed be reliable. The present study examined the relapse situation of alcoholics in terms of the location of the first drink episode, the social environment, and type of beverage consumed and compared this situation to the usual (most frequent) drinking situation prior to treatment.     

Learning and memory of field independent-dependent individuals

It has been proposed that field-independent and field-dependent learners differ more in the processes they use than in the effectiveness of their learning or retention. The present article discusses alternative explanations which emphasize developmental differences and differences in efficiency of performance between field-independent and field-dependent learners. Review of the concept learning literature and some new data suggested that the greater effectiveness of field-independent learners was related to memory efficiency and the ability to conduct combinatorial analysis. Research concerning short-term memory and free recall was also examined. High information load, greater interference potential, and less subjective organization were suggested as factors which contribute to the less efficient memory of field-dependent learners.     

Field dependence and short-term memory

This study examined the relationship between field dependence and short-term memory. It was predicted that relatively field-independent individuals would perform better on short-term memory tests in which a large amount of interference is assumed to be present than would individuals who are more field-dependent. Subjects' appraisals of their own attentional facility, as well as their thoughts and feelings about the experimental tasks, were also elicited, and were looked at in terms of their relationship to field dependence and short-term memory.     

Field dependence-independence and participation in physical activity by college students

Field-independent individuals, compared with field-dependent individuals, have higher sports potential and advantages in sport-related settings. Little research, however, has been conducted on the association of field dependence-independence and participation in physical activity. The study examined this association for college students who participated in physical activities in and beyond physical education classes. The Group Embedded Figures Test distinguished 40 field-dependent from 40 field-independent participants. Activity logs during one semester showed that field-independent participants were significantly more physically active and their physical activity behaviors were more sport-related than those of field-dependent participants.     

Discriminating between alcoholic and nonalcoholic blacks and whites on the MMPI

The purpose of the present study was to investigate the influence of race (black, white) on the MMPI performance of alcoholic and nonalcoholic inpatients. Subjects were 73 (27 black, 46 white) male alcoholic inpatients and 73 (27 black, 46 white) male nonalcoholic psychiatric inpatients. While black and white alcoholics failed to differ on the MMPI, white alcoholics presented as less disturbed and black alcoholics as less defensive and distressed, compared to their respective nonalcoholic counterparts. Furthermore, only white alcoholics were accurately identified by the MMPI 2-4/4-2 high-point pair combination and only white alcoholics achieved more high-point pairs containing Scale 4 relative to nonalcoholic controls.     

目标数量与运动框架旋转角度对不同场认知风格个体多目标追踪表现的影响

通过改变目标数量、运动框架突变旋转角度探究不同场认知风格被试在多目标追踪任务中的表现。结果发现：(1)在任务难度较低(运动参考框架稳定, 目标数量为3和4)和任务难度中等(运动参考框架突变向右旋转20°, 目标数量为4)条件下, 场独立型被试的多目标追踪表现均显著好于场依存型被试。在任务难度较高(运动框架稳定, 目标数量为5以及运动参考框架突变向右旋转40°, 目标数量为4)条件下, 两组被试差异不显著。表明不同场认知风格被试追踪表现受任务难度影响; (2)随着目标数量由3至5增多, 追踪负荷增大使被试的追踪成绩显著下降; (3)相比运动框架稳定, 运动框架向右突变旋转20°和40°均显著削弱了被试的追踪表现。旋转角度变化破坏了场景连续性, 影响了追踪表现。     

Cognitive styles in the development of medical careers

Recent research has shown that academic choice and achievement may be partly a function of the student's standing on the field-dependence-independence cognitive-style dimension. The results of two longitudinal studies suggest that information about field dependence-independence may be of value for student guidance in the medical setting. The first, a study of college undergraduates who early expressed an interest in medicine, showed that these cognitive styles play a discernible role in determining who will eventually enter medical school. The second, a study of medical students, showed that field-dependent and field-independent students subsequently tend to choose different medical specialties. These results are consistent with cognitive-style theory, which proposes that field-independent people will choose vocations that require cognitive restructuring skills, whereas field-dependent people will choose vocations that require greater social-interpersonal involvement.     

Suicide notes in alcoholism

Alcoholism is associated with a vast number of suicides. The most systematic study of suicide among alcoholics is the work of Eli Robins and George Murphy. The suicide notes in these studies have remained unanalyzed to date. The present analysis suggested that these suicide notes of alcoholics did not differ from those of nonalcoholics; core themes in their deaths are unbearable psychological pain, cognitive constriction, indirect expressions, rejection-aggression, and identification-aggression. Although caution is in order in accepting the null hypothesis, we can at least suggest that further study is needed.     

A community-reinforcement approach to alcoholism

Several theoretical approaches to alcoholism exist. An opérant reinforcement approach was used in the present study to develop a new procedure that rearranged community reinforcers such as the job, family and social relations of the alcoholic such that drinking produced a time-out from a high density of reinforcement. The results showed that the alcoholics who received this Community-Reinforcement counseling drank less, worked more, spent more time with their families and out of institutions than did a matched control group of alcoholics who did not receive these procedures. This new approach appears to be an effective method of reducing alcoholism. An analysis in reinforcement terms is presented of the etiology, epidemiology, and treatment of alcoholism.     

Cognitive style and relationship quality in married dyads

Recently, cognitive personality researchers have begun to explore the social and interpersonal relevance of cognitive individual difference variables. Embedded in these examinations, however, is a methodological issue that bears importantly on our understanding of the role of these cognitive orientations in social relations. Specifically, personality studies have typically employed experimentally created dyads which, by limiting the representativeness of the sample, potentially limits the generalizability of the findings to more enduring “real-life” dyads. In the present study, field dependence/field independence was examined as a potential mediator of relationship quality in married dyads. Consistent with Witkin's theory of psychological differentiation, it was predicted that spouses with relatively field-dependent partners and individuals from dyads with similar levels of differentiation would have fewer complaints. Results showed, contrary to the predictions, that husbands married to field-dependent wives and wives from matched dyads had more complaints about their marital relationships. These findings suggest the need for a careful evaluation of the role of cognitive style in the domain of intimate interpersonal relationships. Apparently, it may not be sufficient to generalize about the role of personality in social relationships from the results of studies employing experimentally created dyads or groups to other, more enduring and real-life types of social relationships.     

Denial and self-denigration in the draw-a-person profiles of alcoholics

The present study attempts to cross-validate earlier findings that alcoholics tend to use more denial and are more demeaning of their characters than controls on the objective-projective Apperceptive Personality Test. One hundred nonalcoholic, nonpatient controls were matched to 100 outpatient alcoholics on age, race, and social class. All subjects were given the objective-projective Draw A Person Questionnaire, which was scored for 14 scales. As hypothesized and consistent with the earlier findings, alcoholics used more denial and were more often demeaning of their drawn characters than were controls. These and other exploratory findings are discussed.     

Cognitive styles and moral reasoning

It was hypothesized that field-dependent persons would be reasoning at the conventional level, whereas field-independent persons would reason at the post-conventional level. Data from 7 female and 3 male graduate students in Canada supported the first hypothesis (8 field-independent vs 2 field-dependent scorers), but not the second one.     

A factor analysis of the Kirton Adaption-Innovation Inventory using an alcoholic population

The present study reports a factor analysis of the Kirton Adaption-Innovation Inventory using 103 alcoholic men. Kirton in 1976 and we in an unpublished work in 1986 noted identical factor structures when responses from nonalcoholic populations to the inventory were factor analyzed. Recent reviews regarding personality characteristics of alcoholics suggest characteristics similar to the adaption-innovation concepts of Kirton. This factor analysis for an alcoholic sample supports the validity of the inventory as a measure of problem-solving style of alcoholics.
