Visual and Proprioceptive Determinants of Space Perception and Movement

The present study determined the relationship between perception of the upright in 2-dimensional space and movement accuracy. 161 female Ss were administered the Rod and Frame Test, and 30 Ss, whose scores indicated the greatest and least error in perceptual differentiation, were assigned to 2 experimental groups and measured on accuracy of postural pursuit tracking. The effects of direction of movement and visual field conditions on accuracy of performance were determined by a coordinate postural platform and hybrid computer methods. A direct relationship existed between perception of the vertical in space and accuracy of motor responses and that perceptual integration was affected by the direction of movement and the presence of a stable visual field.     

The Dimensionality of Supervisor Evaluations of Job Performance

This paper presents empirical evidence about the dimensions of supervisor evaluations of employee job performance. Factor analytic results supported the conclusion that supervisors were able to distinguish between two dimensions of job performance. While bivariate correlational analysis indicated that these two dimensions of job performance were similarly related to other measures, a multivariate regression analysis suggests that they are distinguishable constructs.     

The Dimensionality of the Industrial Sales Job Characteristics

Abstract

Sales representative motivation, satisfaction, and performance have been topics of considerable interest to managers and researchers alike for many years. Recently researchers have borrowed conceptualizations from organizational behavior and applied them successfully in the sales setting. For the most part, research on work-related sales representative motivation has focused on either the “expectancy” approach or the “job characteristics” approach. A brief overview is presented, followed by an assessment of the validity of the core dimensions found in the increasingly popular Job Diagnostic Survey in a sales representative context. The managerial implications of the assessment are also discussed.     

The Dimensionality of Locus of Control Among French Students

To learn more about the dimensionality of locus of control, I developed a new internal-external (I-E) scale for French students. Four criteria were used for the construction of the scale: causal explanation and orientation of behavioral outcomes, situational contents, and control ideology. Questionnaires were administered to 200 male and female undergraduates in psychology. A principal-components analysis and a nonmetric multidimensional scaling were used. The hypothesis of the unidimensionality of locus of control was confirmed.     

Apparent Distortions in Photography and the Geometry of Visual Space

In this paper I contrast the geometric structure of phenomenal visual space with that of photographic images. I argue that topologically both are two-dimensional and that both involve central projections of scenes being depicted. However, I also argue that the metric structures of the spaces differ inasmuch as two types of “apparent distortions”—marginal distortion in wide-angle photography and close-up distortions—which occur in photography do not occur in the corresponding visual experiences. In particular, I argue that the absence of marginal distortions in vision is evidence for a holistic metric of visual space that is spherical, and that the absence of close-up distortions shows that the local metric structure possesses a dynamic variable curvature which is dependent upon the distance away of objects being viewed at a given time.

The Dimensionality of Coping Among Chinese Health Care Workers

Abstract

The transactional model defines coping as a process that changes on the basis of the context of an environmental encounter. An instrument used to investigate coping in diverse person-environment interactions is the Ways of Coping Questionnaire (WOC; S. Folkman & R. S. Lazarus, 1988). Although evidence exists to support the basic underlying structure of the WOC in Western societies, no research has been conducted on the instrument's dimensionality in non-Western societies. The authors identified 14 factors for the WOC administered to a sample of health care workers in Beijing, China. The 14 factors identified in the present study were similar to the 8 factors identified in the original validation study (S. Folkman, R. S. Lazarus, C. Dunkel-Schetter, A. DeLongis, & R. J. Gruen, 1986), but they were more content specific.     

Space Perception,Visual Dissonance and the Fate of Standard Representationalism

This paper argues that a common form of representationalism has trouble accommodating empirical findings about visual space perception. Vision science tells us that the visual system systematically gives rise to different experiences of the same spatial property. This, combined with a naturalistic account of content, suggests that the same spatial property can have different veridical looks. I use this to argue that a common form of representationalism about spatial experience must be rejected. I conclude by considering alternatives to this view.     

The Assessment of Dimensionality for Use in Item Response Theory

The application of item response theory (IRT) models requires the identification of the data's dimensionality. A popular method for determining the number of latent dimensions is the factor analysis of a correlation matrix. Unlike factor analysis, which is based on a linear model, IRT assumes a nonlinear relationship between item performance and ability. Because multidimensional scaling (MDS) assumes a monotonic relationship this method may be useful for the assessment of a data set's dimensionality for use with IRT models. This study compared MDS, exploratory and confirmatory factor analysis (EFA and CFA, respectively) in the assessment of the dimensionality of data sets which had been generated to be either one- or two-dimensional. In addition, the data sets differed in the degree of interdimensional correlation and in the number of items defining a dimension. Results showed that MDS and CFA were able to correctly identify the number of latent dimensions for all data sets. In general, EFA was able to correctly identify the data's dimensionality, except for data whose interdimensional correlation was high.     

Dimensionality of women's career orientation

Two factor analytic studies were conducted in order to determine the dimensionality of women's career orientation defined by various extant measures. In Study I, 86 women employed by an insurance company responded to nine different measures of career orientation. A principal axis analysis produced two oblique factors, which were tentatively named Career Centeredness and Career Commitment, respectively. Study II sought to validate the factors found in Study I in a sample of 335 university women in various disciplines and at various class levels. Using the factor pattern from Study I as the target matrix, a restricted maximum likelihood factor analysis showed that two factors similar to those in Study I accounted for all the significant common variance. Based on both statistical criteria and psychological meaningfulness, the two oblique (r=.43) factors were again named Career Centeredness (lifestyle in which one's career is regarded as more important, time consuming, and satisfying than other aspects of life, particularly family) and Career Commitment (lifestyle involving continued employment throughout life stages regardless of financial need or competing obligations). These findings are discussed in the context of changing societal support for women's roles in business.This report is based on a portion of the first author's doctoral dissertation, supervised by the second author, done in the Department of Psychology of New York University.Both authors are currently at Merrill Lynch, 165 Broadway, New York, New York 10080.     

The Dimensionality and Well-being Related Correlates of Work Locus of Control

Abstract

Theoretical and empirical developments with the locus of control construct demonstrate that it is a context-specific multidimensional construct that has implications for stress and well-being. In this paper, the multidimensionality of work-specific locus of control is explored by subjecting Spector's work locus of control scale to principal components analysis. Using samples of 221 university staff and 399 accountants, a two-dimensional structure was uncovered; external agents control and personal control. Correlations with constructs that have been theoretically and empirically associated with locus of control indicate slightly divergent results for the two dimensions, thus demonstrating the importance of treating locus of control as a domain-specific multidimensional construct. In addition, test-retest data with a subsample of 246 accountants suggested that work locus of control may be thought of as a state rather than trait measure.     

The Structure of Partisan Attitudes: Reexamining Partisan Dimensionality and Ambivalence

The true nature of Americans' party attachments remains an area of enduring controversy. Due to inadequate measures, scholars have argued without resolution as to whether partisanship is unidimensional and bipolar, or rather attitudes towards each party are on separate dimensions. Using more appropriate, psychologically specific, multi-item measures of positive and negative partisan evaluations, however, (1) goes a long way towards settling this problematic debate; and (2) allows for explorations of the heretofore unexamined role of ambivalence in partisanship. I find that partisan attitudes are unidimensional and strongly bipolar and that ambivalence weakens the impact of partisan attitudes in both attitudes and behaviors in predictable ways.     

The Dimensionality of Type A Behavior within a Stressful Work Simulation

The present study was conducted to examine the dimensionality of overt Type A behaviors elicited in a simulated stressful work environment. University students played a managerial role while being subjected to time and work-load pressures, and completed the Survey of Work Styles (SWS; Jackson & Gray, 1989). Eighteen behaviors, coded by two raters based on audiovisual recordings, yielded relatively high interrater reliabilities. Principal components analysis revealed four primary factors: Hurriedness, Irritability, Tension of the Lower Extremities, and Restlessness. These factors contribute to an understanding of Type A behavior in that they are the first to be derived from a purely observational approach rather than a combination of observational and self-report methods. Consistent with previous research, differential correlations between the factors and the SWS subscales supported a multi-dimensional interpretation of the Type A behavior pattern. Present findings are compared to those of previous studies of Type A dimensionality.     

视觉表象扫描中的视角大小效应

采用视觉表象的几何距离扫描任务,通过两个实验首次揭示了视觉表象扫描中的视角大小效应。实验一采用3 (视角：2.7°,5.5°和8.2°) × 3 (扫描距离：0.0cm、0.4cm和0.8cm) 组内实验设计,探讨了视角大小这种表象前加工因素是否影响心理扫描的问题;实验二采用8 (视角：2.7°,4.1°,5.5°,6.9°,8.2°,9.6°,12.3°和17.1°) × 2 (扫描距离：0.4cm和0.8cm) 组内实验设计,探讨了视角大小如何影响心理扫描加工过程的问题。结果表明：（1）在视觉表象扫描中,扫描时间会受到表象对应刺激的视角大小影响,即使扫描的几何距离相等,不同视角大小条件下的扫描时间仍存在显著差异;（2）在4°到10°这个视角范围内心理扫描的时间显著短于这个范围之外的扫描时间,6.5°左右是视觉表象扫描的最佳视角。视角大小效应有别于心理扫描的大小效应和距离效应,为Kosslyn的表象计算理论增加了新的内容,具有重要的理论意义。同时它对仪表、图形设计以及棋牌游戏等工作和生活实践具有一定的应用价值
