Twenty-six children diagnosed as having minimal brain dysfunctions (MBD) were compared with 26 controls in a conditinoing and generalization procedure. Skin resistance, heart rate, and muscle action potentials were monitored throughout. Success involved learning which of two tones signalled the accessibility of a penny. Whereas 92 per cent of controls reached the criterion of five successive correct responses, only 62 per cent of MBD’s did. Further, a third of the MBD’s were so maladaptive as to force procedural variations, while only a few minor irregularities occurred with the controls. Quality of performance was related to age, intelligence, and ability to discriminate and remember tones. Controls were more physiologically reactive than MBD’s, especially in skin resistance. Physiologic differentiation of the two tones was significant in both groups of children and appeared concurrently with motor differentiation. The only evidence of physiologic generalization was in the SR data of controls. The possibility that defective arousal structures, or defective coupling of arousal structures and other perceptual and motor structures, could account for the decreased physiologic reactivity, short attention spans, and poor concentration ofsome MBD’s is discussed. This research, in conformity with other laboratory studies of the brain, indicates that motivational as well as cognitive defects may be organically based. 相似文献

The purpose of the present paper is to describe a new technique and a mathematical model--called the "Catch model"--for identifying a face previously seen (i.e., the target face). Both the technique and the model were developed on the basis of the general approach of information processing used with respect to human memory. Subjects were presented with a pair of test faces on each trial. Neither of the test faces was the target face. Their task was to choose from the two test faces the one most similar to the target face. The data furnished by the subjects were used to reconstruct the target face in the following way: At each trial the differentiating values, such as a long nose and blue eyes, of the test face chosen by the subject were recorded. These values were the ones that accounted for the difference between the two test faces. Over the whole run of the test trials, the differentiating values were associated with various frequencies of occurrence. The target face was reconstructed by selecting the differentiating values having the highest frequency of occurrence. Only one differentiating value per facial dimension such as a nose and eyes could be selected. Thus, given that the facial dimension of the nose has three different values consisting of the long, short, and wide varieties of nose, the value chosen would be the one associated with the highest frequency of occurrence. Mathematical derivations show that, given different variations of the proposed technique, the target face will be detected. These derivations were supported by the results of three experiments. 相似文献

By planning the what, where, and when of pursuing a goal, people improve the likelihood that they will ultimately attain that goal. Whereas research to date has explored the breadth of this planning effect and its underlying processes, contextual variables that influence the formation and execution of plans have mostly gone unexplored. In light of the central role played by emotional experience in goal pursuit, its impact on planning remains an open question of both theoretical and practical importance. Here, we suggest that anger and sadness—and their corresponding, distinct cognitive appraisal patterns regarding control—differentially impact (1) the tendency to plan and (2) the implementation of plans. Anger (greater control) led to the formation of more plans for goal-directed behavior (Studies 1 and 2) and faster execution of real behavior as prescribed by predetermined plans (Study 3). Broader implications for theories of emotion and goal pursuit are discussed. 相似文献

Research has demonstrated that use of texting slang (textisms) when text messaging does not appear to impact negatively on children's literacy outcomes and may even benefit children's spelling attainment. However, less attention has been paid to the impact of text messaging on the development of children's and young people's understanding of grammar. This study therefore examined the interrelationships between children's and young adults’ tendency to make grammatical violations when texting and their performance on formal assessments of spoken and written grammatical understanding, orthographic processing and spelling ability over the course of 1 year. Zero‐order correlations showed patterns consistent with previous research on textism use and spelling, and there was no evidence of any negative associations between the development of the children's performance on the grammar tasks and their use of grammatical violations when texting. Adults’ tendency to use ungrammatical word forms (‘does you’) was positively related to performance on the test of written grammar. Grammatical violations were found to be positively associated with growth in spelling for secondary school children. However, not all forms of violation were observed to be consistently used in samples of text messages taken 12 months apart or were characteristic of typical text messages. The need to differentiate between genuine errors and deliberate violation of rules is discussed, as are the educational implications of these findings. 相似文献

The purpose of this study is to investigate whether effective coping strategies play an important role to reduce burnout levels among sexual or substance abuse counselors. The authors examined whether coping strategies mediated or moderated relations between job stress and burnout in a sample of 232 abuse‐specific counselors. Results indicated that self‐distraction and behavior disengagement coping strategies mediated the relationships between 3 job stress variables (workload, role conflict, and job ambiguity) and burnout. Although venting and humor coping strategies positively moderated the relationship between role ambiguity and burnout, active coping strategies negatively moderated the relationship between workload and burnout. 相似文献

Adolescent Motivations to Engage in Pro‐Social Behaviors and Abstain From Health‐Risk Behaviors: A Self‐Determination Theory Approach 下载免费PDF全文

The present study used self‐determination theory to examine adolescents' motivations to engage in charitable donating and community volunteering and to abstain from sexual intercourse and marijuana use. The sample consisted of 419 late adolescents recruited from across the country through an online survey panel. Participants completed online measures of motivations to engage in donating and volunteering, motivations to abstain from sex and marijuana, and single‐item indexes of the four behaviors. Variable‐centered analyses (correlation and regression) found evidence for a general motivational factor, motivational specificity by behavioral domain (positive and negative behaviors), motivational specificity by particular behavior (charitable donating, volunteering, sexual risk‐taking, and marijuana use), and a stronger relative role for autonomous motivations than controlled motivations. Person‐centered analyses (cluster analysis) found four motivation profiles (low motivation, medium motivation, high motivation, and mixed motivation) for all four behaviors and suggested that level of autonomous motivation was a key factor differentiating the groups on levels of behavior. The findings suggest different levels of motivational specificity and highlight the importance of autonomous motivations in predicting behaviors as compared to controlled motivations. Further, similar patterns were found for motivations to engage and to abstain. 相似文献

Implementing Housing First Across Sites and Over Time: Later Fidelity and Implementation Evaluation of a Pan-Canadian Multi-site Housing First Program for Homeless People with Mental Illness 下载免费PDF全文

This article examines later fidelity and implementation of a five‐site pan‐Canadian Housing First research demonstration project. The average fidelity score across five Housing First domains and 10 programs was high in the first year of operation (3.47/4) and higher in the third year of operation (3.62/4). Qualitative interviews (36 key informant interviews and 17 focus groups) revealed that staff expertise, partnerships with other services, and leadership facilitated implementation, while staff turnover, rehousing participants, participant isolation, and limited vocational/educational supports impeded implementation. The findings shed light on important implementation “drivers” at the staff, program, and community levels. 相似文献

There is currently a welcome intensification of interest in the contemporary theological significance of both historical traditions of mystical theology and twentieth‐century theories of mysticism. This review article surveys and evaluates the stimulating range of approaches to these two issues contained in the essays in these volumes. It suggests that the volumes make evident the difficulty of attempting to uncover an underlying conceptual unity in these two historically entangled but deeply different forms of thought. The historical and philosophical sophistication with which many of these essays reflect on these tensions, however, points towards fruitful lines of future enquiry. 相似文献
