A threshold approach to understanding the origins of attachment disorganization

Disorganized attachment in infancy is known to predict a wide range of maladaptive outcomes, but its origins are poorly understood. Parental lack of resolution concerning loss or trauma has been proposed to result in atypical parenting behaviors, which in turn have a disorganizing effect on the parent-child relationship. The authors review the evidence for this transmission pathway, considering other factors (e.g., social environment, child characteristics) that might enrich understanding of the antecedents of disorganization. A threshold approach is proposed to explain (a) why different parental behaviors are linked to disorganization depending on prevailing social conditions and (b) why certain children appear more vulnerable to forming a disorganized attachment relationship.     

A structural modeling approach to the understanding of parenting stress

Tested and cross-validated a multidimensional model of predictors of parenting stress on data from a population-based sample of Swedish mothers (N = 1,081) with children ages 6 months to 3 years. The study was a cross-sectional questionnaire study, focusing on the explanation of variance in parenting stress. Structural equation modeling procedures permitted disentanglement of total, direct, and indirect effects. A Swedish instrument based on parts of the Parent Domain in the Parenting Stress Index was used as a measure of stress. The results provided general support for the proposed model. High workload, low social support, perception of the child as fussy-difficult, negative life events, child caretaking hassles, more children in the family, and high maternal age related directly to more stress. Child irregularity contributed indirectly to mother's experienced stress. No buffering effects of social support were found. Forty-eight percent of the variance in the parenting stress measure was explained by the model. Implications for interventions were discussed.     

A masking approach to the problem of form perception

The effects of deletion of certain components of a dotted triangle are studied, using a masking technique. Masking interference is achieved by varying the density of randomly placed dots within which stimulus triangles must be detected. The results of the study indicate that deletion of the dots composing the corners of the triangles decreases performance no more than deletion of an equivalent number of randomly chosen dots. However, the detectability of the line of dots composing the sides is functionally related to the recognition of the orientation of the triangle. The results suggest that the relationship of the parts of such a stimulus figure may be more important than the specific parts themselves.     

A set-theoretical approach to the problem of hierarchical clustering

A set-theoretical formalization is developed for the problem of generating hierarchically organized collections of subsets, or to use a phrase common in the applied substantive literature, for the problem of hierarchical clustering. A number of terms are introduced to characterize those clustering methods that attempt to limit the size of the overlap between each pair of subsets constructed at a specific “compactness” level. Several examples, motivated primarily by graph theory, are discussed briefly to illustrate the various set-theoretical concepts presented.     

A dispositional approach to understanding individual power in organizations

This research examined an alternative way of thinking about individual sources of power in organizational settings: the impact of individuals' disposition toward seeking power (nDom) on self perceptions of power. A computer-based experimental simulation allowed structural features of the job and day-to-day events on the job to be controlled across subjects, while assessing the impact of nDom on power. High nDom individuals reported higher self perceptions of power than did low nDom individuals, and these effects were significant above and beyond the actual degree of success or failure experienced by individuals on the job. Analysis also revealed an attenuating interaction effect between nDom and success on the job which suggested that high nDom individuals may be less susceptible to fluctuations in self perceptions of power based on daily job events.The author thanks Lynn Harland for her helpful contributions in conducting this research.     

A self-regulation approach to understanding citizenship behavior in organizations

Researchers have generally taken a between-person, cross-sectional approach to understand why employees engage in organizational citizenship behavior (OCB). However, in light of recent work indicating that motivated behavior in organizations is often better understood using a within-person, longitudinal approach, we conceptualize citizenship performance as a dynamic cycle that varies over time. Specifically, we use self-regulation theory to explain how employees seek to fulfill goals through their OCBs, make plans to achieve those goals, engage in OCBs, and process feedback regarding their citizenship behavior. In doing so, we highlight the role played by chronic and working self-concept orientations. We also explore the way affective states influence self-regulation and citizenship, discuss unconscious or habitual acts of citizenship, and address the ways in which self-regulation and citizenship may vary over time.     

A review and critique of the process approach in neuropsychological assessment

This paper surveys the process approach literature with an emphasis on higher level cognitive functions like attention and concentration, learning and memory, and problem solving and executive functioning. In particular, it discusses organizational strategies and kinds of errors found on a variety of tests as well as behavioral, situational, and interpersonal issues as they relate to test procedures. It critiques the process approach and suggests future directions.     

A functional approach to understanding attitudes toward AIDS victims.

Attitudes toward victims of AIDS were conceptualized as serving three possible functions: a value-expressive function (e.g., stigmatization), an ego-defensive function (e.g., homosexual prejudice), or a knowledge function (e.g., victim derogation). These functions were evaluated by having a sample of U.S. undergraduates respond to a victim who had contracted AIDS by one of three different means: a blood transfusion, a sexual encounter of a homosexual nature, or intravenous drug use. Subjects then indicated their beliefs about the victim's responsibility for the disease, feelings toward the victim, and likely behavioral interactions with the victim. The findings provided most support for the knowledge function of attitudes toward AIDS victims.     

An information-based approach to action understanding

It has been proposed that the ability to make sense of other agents' behavior relies on the activation of internal mechanisms that map action perception onto action execution. In this study we explored the constraints on this ability introduced by eyeheight-scaled information in the optic array. Short and tall participants provided maximum overhead reaching judgments for themselves and another participant. Perceptual information was manipulated by changing the participants' optically specified eyeheight. Observers were modestly accurate in perceiving maximum overhead reach for themselves and for another actor whose action capabilities differed. Perceived maximum overhead reach increased for both self- and other-judgments when the perceiver's eyeheight was increased. The results suggest an important role of perceptual information that has gone unrecognized in existing accounts of action understanding and prediction.     

A political economy approach to understanding the economic incorporation of Chinese sub-ethnic groups

This paper outlines the economic experiences of Toronto’s Chinese, 80% of whom are immigrants mostly arriving in the last two decades. Based on the 1996 census data, labour market participation and economic performance of various. Chinese sub-groups were compared. The findings contribute to an understanding of how selective immigration policies and world geopolitical changes can account for differences in economic adaptation and integration of sub-ethnic groups.
