Deconstructing, reconstructing, preserving Paul E. Meehl's legacy of construct validity

The question of the status of cause-and-effect explanations of human behavior that posit physically existing causative factors and those that, on the other hand, posit hypothetical entities in the form of "useful fictions" has a long history. The influence of the works of Jeremy Bentham and Hans Vaihinger, as well as the later influence of Francis Galton, is described. Issues of the validity of hypothetical constructs and related problems of measurement and definition as found in psychoanalytic theory construction and in trait theory are examined. The significant and continuing interest generated by the landmark studies of K. MacCorquodale and P. E. Meehl (1948) and L. J. Cronbach and P. E. Meehl (1955) as well as the central importance of P. E. Meehl's thinking are described.     

Borderline personality disorder features predict negative outcomes 2 years later

In a sample of 351 young adults, the authors assessed whether borderline personality disorder (BPD) features prospectively predicted negative outcomes (poorer academic achievement and social maladjustment) over the subsequent 2 years, over and above gender and both Axis I and Axis II psychopathology. Borderline traits were significantly related to these outcomes, with impulsivity and affective instability the most highly associated. The present findings suggest that the impulsivity and affective instability associated with BPD leads to impairment in relating well with others, in meeting social role obligations, and in academic or occupational achievement. Therefore, these may be especially important features to target in interventions for BPD.     

School-age children's perceptions of a person who stutters

The present study examined the perceptions school-age children have of stutterers. Four groups of fourth and fifth grade students viewed a videotape with either the speaker stuttering or not stuttering while reading a poem. A semantic differential scale of bi-polar adjective pairs was used to rate the speaker on intelligence and personality traits. The current study found that there is a significant difference between school-age children's perceptions of stutterers and nonstutterers with the ratings for the disfluent speaker more negative than the ratings for the fluent speaker. It was found that children did not rate personality and intelligence related traits differently. This information can be used to validate the need for education regarding stuttering for children and those who work with children. EDUCATIONAL OBJECTIVES: The reader will learn about and be able to (1). identify perceptions of stutterers by a variety of groups; (2). discuss the implications of research on perceptions of stutterers; and (3). compare/contrast children and adults and their perceptions.     

Customers' perceptions of salespersons' orientation and susceptibility to salespersons' influence

This study examined correlations of scores for salespersons' and customers' orientation, as indicated by a modified Salesperson Orientation-Customer Orientation scale, with self-reported consumers' susceptibility to salespersons' information, recommendations, and relational influence. Vehicle purchasers provided 508 useable survey responses. Correlations for customers' perceptions of both salespersons' orientation (-.39 and -.21) and customers' orientation (.39 and .24) were related to self-reports of susceptibility to salespersons' information and relational influence.     

Cortical morphology associated with language function in neurofibromatosis,type I

Neurofibromatosis, type I (NF-I) is associated with verbal and nonverbal neuropsychological deficits and neuroanatomical anomalies. Few relationships between CNS abnormalities and cognitive function in this population, however, have been found. Reading disabilities and developmental language impairments in the general population have been associated with particular morphologic features in inferior frontal gyrus (IFG) and Heschl's gyrus (HG). We compared the morphology of these regions in children with NF-I and controls. Verbal skills in NF-I were related to IFG morphology, such that individuals with NF-I who showed "typical" gyral patterns in the right hemisphere performed worse across language measures than those showing an extra "atypical" gyrus. A doubling of HG in the left and right hemispheres was also significantly associated with performance on several neuropsychological measures. This is the first study to link regional gyral morphology with language function in NF-I. A possible molecular basis for the observed relationships is discussed.     

Now you feel it, now you don't: frontal brain electrical asymmetry and individual differences in emotion regulation

Recent theoretical accounts of emotion regulation assign an important role in this process to the prefrontal cortex, yet there is little relevant data available to support this hypothesis. The current study assessed the relation between individual differences in asymmetric prefrontal activation and an objective measure of uninstructed emotion regulation. Forty-seven participants 57 to 60 years old viewed emotionally arousing and neutral visual stimuli while eyeblink startle data were collected. Startle probes were also presented after picture presentation to capture the persistence or attenuation of affect following the offset of an emotional stimulus. Subjects with greater relative left-sided anterior activation in scalp-recorded brain electrical signals displayed attenuated startle magnitude after the offset of negative stimuli. This relation between resting frontal activation and recovery following an aversive event supports the idea of a frontally mediated mechanism involved in one form of automatic emotion regulation.     

Facts,values, and policies: a comment on Howard H. Kendler (2002)

In a recent article, Howard H. Kendler (2002) criticized Kenneth B. Clark and the other social scientists who worked in Brown v. Board of Education for polluting their science with value judgments. This article argues that Kendler's critique is misguided because it conflates a policy judgment with a value judgment. In addition, Kendler inconsistently applied his own standard of objectivity when he examined in the social science used in Brown.     

Differences in psychosocial experiences of employed, unemployed, and student samples of young adults

The author conducted this cross-sectional study to assess the extent to which employed, unemployed, and student samples of young adults could be differentiated on the basis of psychosocial experiences. Forty-four employed, 41 unemployed, and 42 student volunteers completed measures of emotional distress, time structure, financial strain, skill use, task variety, social support, and demographic information. After the effects of educational and income differences were statistically controlled, results indicated that unemployed participants reported poorer functioning than employed and student respondents on most measures. In a discriminant function analysis, 66% of the sample was correctly identified from scores on psychosocial measures, with higher classification rates for employed and unemployed participants. The findings provide additional support for contextual models of mental health and suggest that full-time education partially buffers the negative psychological consequences of unemployment when opportunities for employment are absent.
