The influence of advance information about target location and visual feedback on movement planning and execution.

This study was designed to determine if movement planning strategies incorporating the use of visual feedback during manual aiming are specific to individual movements. Advance information about target location and visual context was manipulated using precues. Participants exhibited a shorter reaction time and a longer movement time when they were certain of the target location and that vision would be available. The longer movement time was associated with greater time after peak velocity. Under conditions of uncertainty, participants prepared for the worst-case scenario. That is, they spent more time organizing their movements and produced trajectories that would be expected from greater open-loop control. Our results are consistent with hierarchical movement planning in which knowledge of the movement goal is an essential ingredient of visual feedback utilization.     

Belief and believing

Conclusion This essay has been somewhat programmatic in quality but that is not accidental. It has tried to identify some elements, historical and philosophical, that might provide a context within which an adequate discussion of the concept of belief and its recent diverse employment might be measured. Not very much has been solved, but perhaps some issues have become clearer.     

Psychometric evaluation of the Fear of Positive Evaluation Scale in patients with social anxiety disorder

The Fear of Positive Evaluation Scale (FPES; J. W. Weeks, R. G. Heimberg, & T. L. Rodebaugh, 2008) was designed to assess fear of positive evaluation, a proposed cognitive component of social anxiety. Although previous findings on the psychometric properties of the FPES have been highly encouraging, only 1 previous study has examined the psychometric profile of the FPES in a sample of patients with social anxiety disorder (T. A. Fergus et al., 2009). The primary purpose of the present study was to conduct a large multisite examination of the psychometric profile of the FPES among patients with a principal diagnosis of social anxiety disorder (n = 226; generalized subtype = 97.8%). Responses of nonanxious control participants (n = 42) were also examined. The factorial validity, internal consistency, test-retest reliability, construct validity, and treatment sensitivity of the FPES were strongly supported by our findings. Furthermore, an FPES cutoff score was identified for distinguishing levels of fear of positive evaluation characteristic of patients with social anxiety disorder from those characteristic of the control group. Results provide additional support for the psychometric properties of the FPES in clinical samples.     

The bivalent fear of evaluation model of social anxiety: further integrating findings on fears of positive and negative evaluation

Accumulating evidence supports the premise that fear of evaluation in general is important in social anxiety, including fear of positive evaluation (FPE) as well as fear of negative evaluation (FNE). This study tested various hypotheses pertaining to a novel, expanded conceptualization of social anxiety involving these two distinct fears: the bivalent fear of evaluation (BFOE) model. Responses from a large undergraduate sample (N = 585) were examined. In addition, responses from a subsample of participants qualifying for a probable diagnosis of social anxiety disorder (SAD; n = 133) were examined, via mediational analyses, for potential mechanisms underlying FPE within highly socially anxious individuals. FPE exhibited a unique and significantly stronger relationship with concerns of social reprisal due to making positive impressions than did FNE. FPE related uniquely and negatively to trait positive affect/automatic thoughts, whereas FNE, FPE, and social anxiety all related uniquely and positively to trait negative affect/automatic thoughts. FPE, FNE, and social anxiety all related uniquely and positively to disqualification of positive social outcomes (DPSO). However, FPE related most strongly to DPSO attributions at the level of the self, and these attributions mediated the relationship between FPE and negative automatic thoughts in an analog clinical sample. Concerns of social reprisal due to making positive impressions on others mediated the relationship between FPE and DPSO attributions to others in an analog clinical sample. The obtained findings replicate and extend support for the BFOE model of social anxiety. Implications for the theoretical conceptualization and treatment of SAD are discussed.     

Combined therapy with borderline and narcissistic inpatients at the cassel hospital

An account is given here of a rather unorthodox approach to psychodynamic therapy with Borderline patients in part of the therapeutic community at the Cassel Hospital. ‘Combined therapy’ here refers to the setting in which one therapist sees patients in groups and individual sessions concurrently. The paper demonstrates the manner in which this approach brings to the fore the massive destructiveness and rage which so often lies at the core of these patients' difficulties. This is done by describing the development of the group over its first nine months. The therapist comes to be split in the patient's perception, the group sessions representing separation in all its most hated aspects rather than as a prerequisite for differentiation and growth. The resultant rage and destructiveness threaten to render the group unworkable and dangerous. The individual sessions, by contrast, represent a fantasy of being regressed and at one with the ideal mother. It is my belief that these difficulties can be contained only within a therapeutic community. The strength of this approach lies in the vivid reconstruction of a central conflict for these patients and corresponding potential for working through difficulties in the area of separation and individuation. It is also particularly effective in bringing the therapeutic community alive within the therapy. The discussion attempts to address some of the complex theoretical issues raised by the transformation of the transference in both settings which occurs when they are used together and with the same therapist.     

Complicating race: the relationship between prejudice, race, and social class categorizations

Although racial stereotyping and prejudice research have received considerable attention, the important element of social class has been largely excluded from social psychological research. Using the Statement Recognition Procedure, two experiments investigated social categorization along race and social class dimensions, the influence of racial and social class prejudice on these categorizations, and differences between White and Black perceivers. Analyses conducted at the subtype of race and social class memberships demonstrated differing patterns of categorization based on subtype membership. For example, lowerclass Black targets were primarily categorized by race, whereas middle-class Black targets were primarily categorized by social class. The results demonstrate the importance of considering social class membership independent of and in conjunction with race. Theoretical and methodological implications regarding the study for race and social class categorizations are discussed.     

Temporal constraints in the control of prehensile movement

Three experiments were conducted to investigate the control of the manipulation (i.e., finger-thumb aperture) and transportation (i.e., wrist velocity) components in prehensile movement (Jeannerod, 1981, 1984). In all experiments, subjects were seated and instructed to grasp a dowel mounted on a joystick following a discrete movement over a set distance. Thus, the amount of dowel movement following the grasp could be determined. In Experiment 1, the tolerance (i.e., the amount of allowable dowel movement) was manipulated using a computer-generated boundary around the dowel. The results indicated that the transportation component changed dependent on the tolerance condition, and there were trends that maximum aperture was also affected. Experiment 2 manipulated both tolerance and dowel size (i.e., diameter) factorially in a within-subject design. Dowel size affected only the manipulation component, supporting Jeannerod's (1981) earlier work, but tolerance clearly influenced both components. Experiment 3 investigated Wing, Turton, and Fraser's (1986) proposition that speed of movement influences aperture size. Distance and movement time were combined factorially to produce conditions with different average velocities. Maximum aperture was dependent on the movement time rather than the speed of movement. The relation between the control of the components was examined by using a new method of calculating within-trial correlations between aperture size and wrist velocity in Experiments 2 and 3. The correlations were related to the temporal aspects of the movement with higher correlations in the rapid movement time conditions. Also, the temporal occurrence of maximum aperture remained invariant across the different movement conditions. In general, the results suggest a strong functional linkage between the two components, which may be dependent on the temporal characteristics of the movement.     

The virtues of scientific psychology: A reply to Harzem

Harzem recently expressed the opinions that, beginning in the 1960s, the progress of scientific psychology has been deferred and that psychological research has failed to address important social issues. He proposed that progress be resumed by taking up, anew, the experimental analysis of behavior. The present reply provides evidence inconsistent with Harzem's assertions regarding the state of contemporary, scientific psychology and questions the wisdom of disregarding the significant body of data and theory that currently are available to pursue the, as yet, unfulfilled promises of the experimental analysis of human behavior.     

CDAscal: An algorithm for assessing the correspondence of one or more vectors to a symmetric matrix using ordinal regression

An algorithm for assessing the correspondence of one or more attribute rating variables to a symmetric matrix of dissimilarities is presented. The algorithm is useful as an alternative to fitting property variables into a multidimensional scaling space. Rather than requiring a two step process of first deriving a multidimensional space and then fitting variables individually into the space, the algorithm directly assesses the correspondence of each variable to the symmetric matrix and permits a regression extension such that a set of variables can be considered simultaneously. The relation between the matrix and the variables is determined by evaluating pairs of pairs relations, . Though the algorithm requires only ordinal assumptions, the correspondence may be computed intervally also. Multiple ordinal regression is performed with the values derived from the matrix serving as the dependent variable and those derived from the attribute ratings serving as the independent variables. Standard multiple regression statistics forR-square,F, andt are calculated as well as measures of ordinal association between the vectors and the matrix.
