Training play behavior in a 5-year-old boy with developmental disabilities

The purpose of the current study was twofold: (a) to investigate if it was possible to train three different games (both as a leader and as a participant) to a child with developmental disabilities through interaction with 4 typically developing peers, and (b) to examine if correct responding would be maintained after the training was faded. A multiple probe design across three games was used. The results showed that the child learned both skills as a leader and as a participant in all three games, and that skills were maintained for a period of 3 weeks after the training had stopped.     

Is who you are who you're talking to? Interpersonal style and complementarity in mixed-sex interactions

To investigate interpersonal theory, the authors examined the social behavior of 112 previously unacquainted male-female pairs collaborating on a joint task. Structural equation modeling analyses provided clear evidence of complementarity: In addition to trait affiliation and dominance both predicting situational behavior, each interaction partner's behavior influenced the other's in accordance with the theory, eliciting similar levels of affiliation and opposite levels of dominance. There were also clear biases related to participants' interpersonal traits: When behavior, as indexed by observers, was held constant, more trait affiliative participants tended to view themselves and their partner as warmer during the interaction; likewise, more trait dominant participants perceived themselves to act more dominantly than they actually did. Throughout, there were no sex differences.     

Task switching is not cue switching

With the aim of reducing cognitive control in task switching to simpler processes, researchers have proposed in a series of recent studies that there is little more to switching tasks than switching cues. The present study addresses three questions concerning this reduction hypothesis. First, does switching cues account for all relevant variance associated with switching tasks? Second, how well does this hypothesis generalize beyond the experimental procedure from which it was developed? Third, how well does this new procedure preserve relevant measures such as task-switch cost? The answers (no; not very; not very) suggest that task switching does not reduce to cue switching.     

Family-of-Origin Predictors of Hostile Conflict in Early Marriage*

This study used data from 367 married couples to examine the relationship between select family-of-origin variables measured during engagement and hostile marital conflict measured 4–7 years later. Each spouse completed family-of-origin measures from the PREParation for Marriage questionnaire during their engagement. Four to seven years later, they completed a measure of hostile marital conflict involving insults, name calling, unwillingness to listen, and lack of emotional involvement. Wives mother–child relationship and the quality of parental discipline, as well as the husbands perceived quality of their parents marriage, were predictive of wives perception of hostile conflict in their marriages. Only wives quality of parental discipline was predictive of husbands perception of hostile marital conflict. Implications for premarital counseling and marital therapy are discussed.This is a revised version of a poster presented at the Annual Conference of the National Council on Family Relations, Irvine, California, November, 1999.     

Alternative dimensional models of personality disorder: finding a common ground

The recognition of the many limitations of the categorical model of personality disorder classification has led to the development of quite a number of alternative proposals for a dimensional classification. The purpose of this article is to suggest that future research work toward the integration of these alternative proposals within a common hierarchical structure. An illustration of a potential integration is provided using the constructs assessed within existing dimensional models. Suggestions for future research that will help lead toward a common, integrative dimensional model of personality disorder are provided.     

Multiple hypnotizabilities: differentiating the building blocks of hypnotic response

Although hypnotizability can be conceptualized as involving component subskills, standard measures do not differentiate them from a more general unitary trait, partly because the measures include limited sets of dichotomous items. To overcome this, the authors applied full-information factor analysis, a sophisticated analytic approach for dichotomous items, to a large data set from 2 hypnotizability scales. This analysis yielded 4 subscales (Direct Motor, Motor Challenge, Perceptual-Cognitive, Posthypnotic Amnesia) that point to the building blocks of hypnotic response. The authors then used the subscales as simultaneous predictors of hypnotic responses in 4 experiments to distinguish the contribution of each component from general hypnotizability. This analysis raises interesting questions about how best to conceptualize and advance measurement of the ability to experience hypnosis.     

Sensory consciousness explained (better) in terms of ‘corporality’ and ‘alerting capacity’

How could neural processes be associated with phenomenal consciousness? We present a way to answer this question by taking the counterintuitive stance that the sensory feel of an experience is not a thing that happens to us, but a thing we do: a skill we exercise. By additionally noting that sensory systems possess two important, objectively measurable properties, corporality and alerting capacity, we are able to explain why sensory experience possesses a sensory feel, but thinking and other mental processes do not. We are additionally able to explain why different sensory feels differ in the way they do.     

Testing hypotheses regarding the causes of comorbidity: examining the underlying deficits of comorbid disorders

The authors examined the validity of a method commonly used to test alternative hypotheses regarding the causes of comorbidity: the examination of underlying deficits of comorbid disorders. The authors simulated data in which the true causes of comorbidity were known, then compared the patterns of underlying deficits of the comorbid disorders found in the simulated data with the predicted results. The method of examining the underlying deficits of comorbid disorders could distinguish between several comorbidity models, including those that could not be distinguished well using other methods. The ability to distinguish the correct model decreased as the sample size and the correlation between the underlying deficits and the symptom scores decreased, suggesting that the issue of power should be considered carefully.
