There is currently a significant amount of interest in understanding and developing theories of realization. Naturally arguments have arisen about the adequacy of some theories over others. Many of these arguments have a point. But some can be resolved by seeing that the theories of realization in question fall under different conceptual traditions with different but compatible goals. The arguments I will discuss fit a general pattern. A philosopher argues that one theory of realization is better than another because it provides a better explanation for a particular range of phenomena, say, accounting for common sense cases, or cases within the sciences, when in fact the theories in question are not genuine competitors. I will first describe three different conceptual traditions that are implicated by the arguments under discussion. I will then examine the arguments, from an older complaint by Norman Malcolm against a familiar functional theory to a recent argument by Thomas Polger against an assortment of theories that traffic in inherited causal powers, showing how they can be resolved by situating the theories under their respective conceptual traditions.  相似文献

Association of socially demanding kin relations, mother’s emotional support, behavioral control/monitoring, family organization and psychological control with adolescent’s internalizing and externalizing problems were assessed in 200 economically disadvantaged, African American mothers and adolescents. Demanding kin relations and mother’s psychological control were positively associated with adolescent’s internalizing problems. Demanding kin relations also moderated the association of control/monitoring, family organization, and psychological control, with internalizing. For mothers with more demanding kin relations, increased control/monitoring was associated with increased adolescent internalizing. In comparison, increased control/monitoring was associated with decreased adolescent internalizing for mothers with less demanding kin relations. Negative association of family organization with internalizing was more apparent for mothers with more compared to less demanding kin relations. Positive association of mother’s psychological control with internalizing was more apparent for mothers with more compared to less socially demanding kin relations. Demanding kin relations and mother’s psychological control were positively associated with adolescent’s externalizing problems. Mother’s emotional support and family organization were negatively associated with externalizing. Also, negative association of family organization with externalizing was more apparent for families with more compared to less demanding kin relations. The need for research on the factors associated with negative relation with kin was discussed.  相似文献

In face of the multiple controversies surrounding the DSM process in general and the development of DSM-5 in particular, we have organized a discussion around what we consider six essential questions in further work on the DSM. The six questions involve: 1) the nature of a mental disorder; 2) the definition of mental disorder; 3) the issue of whether, in the current state of psychiatric science, DSM-5 should assume a cautious, conservative posture or an assertive, transformative posture; 4) the role of pragmatic considerations in the construction of DSM-5; 5) the issue of utility of the DSM ?C whether DSM-III and IV have been designed more for clinicians or researchers, and how this conflict should be dealt with in the new manual; and 6) the possibility and advisability, given all the problems with DSM-III and IV, of designing a different diagnostic system. Part I of this article took up the first two questions. Part II will take up the second two questions. Question 3 deals with the question as to whether DSM-V should assume a conservative or assertive posture in making changes from DSM-IV. That question in turn breaks down into discussion of diagnoses that depend on, and aim toward, empirical, scientific validation, and diagnoses that are more value-laden and less amenable to scientific validation. Question 4 takes up the role of pragmatic consideration in a psychiatric nosology, whether the purely empirical considerations need to be tempered by considerations of practical consequence. As in Part 1 of this article, the general introduction, as well as the introductions and conclusions for the specific questions, are written by James Phillips, and the responses to commentaries are written by Allen Frances.  相似文献

Suicide ideation among the homeless is 10 times more common than in the general population. Cognitive theories of depression and hopelessness propose to explain suicidality; however, as yet, none of these fully account for the phenomenon. Shneidman has suggested a theory of psychache or unbearable psychological pain to explain suicidality. This theory has found support among low-risk populations but has not been extensively tested within a high-risk population. The current research assessed the utility of psychache among men who are homeless (N = 97). In support of Shneidman's theory, analyses revealed that psychache was a stronger predictor of suicide ideation than was depression, hopelessness, or life meaning.  相似文献

A poor understanding of behaviour change mechanisms has hindered the development of effective physical activity interventions. The aim of this study was to identify potential mediators of change in a home-based resistance training (RT) program for obese individuals with type 2 diabetes. Obese individuals with type 2 diabetes (N?=?48) were randomly allocated to either an RT intervention (n?=?27) or a control group (n?=?21) for the 16-week study period. The study sample included 16 men and 32 women and the mean age of participants was 54.4 (±11.7) years. Participants in the RT group received a multi-gym and dumbbells and home supervision from a certified personal trainer. RT behaviour was measured using a modified Godin Leisure Time Questionnaire. Social-cognitive constructs were measured and tested in a mediating variable framework using a product-of-coefficients test. The intervention had a significant effect on RT behaviour (p?相似文献

Two studies investigated whether an early recall opportunity, in the form of a self‐administered interview (SAI), reduced forgetting and protected against the negative consequences of post‐event misinformation. In both studies, participants viewed a simulated crime on DVD after which half immediately recorded their statement by using the SAI, whereas control participants did not have an immediate recall opportunity. Following a delay, participants were presented with misinformation encountered either in a misleading news report (Study 1) or in the form of misleading cued‐recall questions (Study 2). Results showed that participants who had completed a SAI after witnessing an event were significantly less prone to forgetting and significantly more resistant to the negative consequences of misinformation. The SAI was able to protect both the quantity and quality of information about a previously witnessed event. Applied implications are discussed. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

The present experiment examined the role of cognitive flexibility in the consistency of truth tellers' and liars' reports. We expected liars to be less flexible (less able to report an experience in different ways) and hence less consistent than truth tellers when asked to describe an event in different ways (e.g. verbally and pictorially). In the experiment, truth tellers entered a room and performed several tasks, whereas liars did not enter the room or perform the tasks but attempted to convince an interviewer that they did. Truth tellers and liars were interviewed twice about the room and tasks, and were asked to express their answers either the same way on both interviews (e.g. verbally then again verbally) or in different ways (e.g. verbally then pictorially). In support of the cognitive flexibility hypothesis, liars' reports were less consistent than truth tellers' reports, particularly when reporting in different ways across interviews. Theoretical and practical implications are discussed. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

Managers play a pivotal role in the innovation process; yet, the mechanisms through which managers enhance or undermine innovation are not well understood. Drawing upon self-concordance theory, we argue that managers can augment employees' self-concordance—defined as the congruence of goals and actions with inner values and preferences—through transformational behavior and thereby contribute to innovation. However, transformational behavior is closely coupled to another form of influence, namely, process management, the attempt to directly manage innovation-related activities. This form of managerial influence reduces employees' self-concordance and thereby undermines innovation. We test our conceptual model in a sample of 188 innovation projects using a contextualized method that asked employees to assess their self-concordance and their managers' behavior during each project. Managers evaluated for each project the innovativeness of the outcome. Multilevel path-analysis provided support for our hypotheses. We discuss future research implications to disentangle innovation-facilitating and innovation-undermining facets of managerial influence.  相似文献

This article provides a selective review of time perception research, mainly focusing on the authors' research. Aspects of psychological time include simultaneity, successiveness, temporal order, and duration judgments. In contrast to findings at interstimulus intervals or durations less than 3.0–5.0 s, there is little evidence for an “across-senses” effect of perceptual modality (visual vs. auditory) at longer intervals or durations. In addition, the flow of time (events) is a pervasive perceptual illusion, and we review evidence on that. Some temporal information is encoded All rights reserved. relatively automatically into memory: People can judge time-related attributes such as recency, frequency, temporal order, and duration of events. Duration judgments in prospective and retrospective paradigms reveal differences between them, as well as variables that moderate the processes involved. An attentional-gate model is needed to account for prospective judgments, and a contextual-change model is needed to account for retrospective judgments.  相似文献
