Do behavioral responses mediate or moderate the relation between cardiovascular reactivity to stress and parental history of hypertension?

To examine whether differences in behavioral responses to stress mediated or moderated the relation between cardiovascular response to stress and parental history of hypertension, 64 healthy undergraduates-16 men with hypertensive parents (PH+), 16 men without hypertensive parents (PH-), 16 PH+ women, and 16 PH- women-participated in a mental arithmetic task, mirror tracing task, and 2 interpersonal role plays. PH+ participants exhibited higher resting heart rates than PH- participants and higher resting systolic blood pressures (SBPs) than PH- women. PH+ participants exhibited greater SBP responses to tasks and engaged in more negative verbal and nonverbal behavior across tasks than PH- counterparts. Differences in behavioral responding neither mediated nor moderated the observed relation between parental history status and SBP response to stress.     

Super-learning of Causal Judgements

In three experiments, participants learned which of a variety of foods were capable of causing an allergic reaction in a hypothetical patient during training in which a compound of a treatment and a target food cue was paired with the reaction. In Experiment 1 the causal ratings of the target cue were increased if the treatment cue was pretrained as a preventative cause of the reaction. Experiments 2 and 3 demonstrated that the magnitude of this superlearning is unaffected by the order of compound and treatment cue training. The final study also showed that forward super-learning is not induced solely by simple exposure to the treatment cue prior to compound training but, rather, depends upon training the treatment cue as a preventative cause, whereas retrospective super-learning may be due merely to exposure of the treatment cue. These results are problematic for contingency-based accounts of causal induction but accord with modified and extended associative theories.     

Activities of daily living in children with developmental coordination disorder: dressing, personal hygiene, and eating skills

In order to understand how age, culture, and problems in motor coordination impact the performance of activities of daily living, we used focus groups and in-depth interviews with Australian and Canadian parents to examine activities of daily living of younger (5-7 years of age) and older (8-9 years of age) children with and without DCD. By comparison with their typically developing age group, children with DCD had more difficulty with dressing, personal hygiene, and eating skills. Difficulties with postural control and fine-motor skills were reported to contribute to poorer performance of activities of daily living. As expected, competence in the performance of activities of daily living improved in the older children with and without DCD and there were few differences in the performance of daily living tasks between typical children in Australia and Canada. Overall, the motor difficulties of children with DCD had a significant impact on performance of a wide range of daily activities.     

Physiological,affective, and behavioral responses to interpersonal conflict among males from families with different levels of cohesion and adaptability

To examine the relation between characteristics of a person's family of origin and cardiovascular, behavioral, cognitive, and affective response to interpersonal conflict, responses of 15 young males from families rated as extreme (EXT) on scales of cohesion (enmeshed or disengaged) or adaptability (chaotic or rigid) were compared to those of 25 young males from families rated as balanced (BAL) on measures of cohesion and adaptability. Subjects participated in two interpersonal role-play conflict situations, one with a male confederate and the other with a female confederate. Measures of heart rate (HR), blood pressure, and indices of both positive and negative verbal and nonverbal behaviors were obtained during each scenario and self-reported measures of positive and negative cognitive self-statements and affective response were obtained following each conflict scene. Results showed that, in contrast to BAL males, EXT males exhibited more negative verbal and nonverbal behavior, less positive nonverbal behavior, higher ratings of state anxiousness during conflict, and higher HR responses during the interaction with the male confederate than the female confederate. These findings suggest that exposure to a family environment with extreme levels of cohesion and adaptability impacts how an individual responds to interpersonal conflict in young adulthood.     

The implicit theories approach to the self-monitoring controversy

In the face of uncertainty and disagreement about the meaning and measurement of the self-monitoring construct, the author proposes an implicit theories approach to shed light on what self-monitoring scales may be tapping. The first study explored people's notions of what high and low self-monitors are like, based on the statements in the 18-item Self-Monitoring Scale (Gangestad and Snyder, 1985). The second study compared that measure with Lennox and Wolfe's (1984) Revised Self-Monitoring Scale and examined defensive motivation within the scales. The third study consisted of two experiments to determine whether subjects perceived the items of Gangestad and Snyder's Self-Monitoring Scale as reflecting a unitary latent entity or separate, contradictory variables. It was concluded that the implicit theories approach appears to be a useful complement to traditional factor analytic studies, providing new ways of looking at a personality construct, clarifying some theoretical issues, and generating hypotheses for future research.     

Paper and voice MAYSI-2: format comparability and concordance with the voice DISC-IV

The authors examine the comparability of paper and voice formats of the Massachusetts Youth Screening Instrument-Second Version (MAYSI-2) as well as each format's concordance with the Voice Diagnostic Interview Schedule for Children (DISC) among adjudicated youth. Comparability is assessed among 248 youths admitted to a South Carolina Assessment Center. Mean scores and alpha coefficients are calculated, and area under the curve and positive and negative predictive values are used to compare concordance to the DISC. Paper and voice formats are significantly correlated, have similar alpha coefficients, and have comparable concordance with the DISC, suggesting that the MAYSI-2 paper and voice formats are comparable instruments. The voice format may be preferable to the paper format for screening justice youth for mental health problems because it may reduce incomplete data and increase reporting of stigmatized behaviors and because of its ability to automatically generate scored reports and aggregate data.     

Re-examination of the role of within-compound associations in the retrospective revaluation of causal judgements

We investigated blocking and retrospective revaluation of causal judgements using a scenario in which food cues acted as potential causes of an allergic reaction as the outcome. In the blocking contingency,the treatment cues were either paired or unpaired with the outcome prior to a second stage in which sequential compounds of treatment and target cues were paired with the outcome. The order of this compound and treatment training was reversed in retrospective revaluation contingencies. When the interstimulus interval between the treatment and target cues was unfilled on compound trials (Experiments 1 and 3), both blocking and retrospective revaluation were observed in that the target cue trained in compound with the paired treatment cue attracted lower causal ratings than the target cue trained in compound with the unpaired treatment cue. By contrast, performing a mental arithmetic task using numerals presented during the interstimulus interval had no effect on the magnitude of blocking but rendered retrospective revaluation unreliable (Experiments 2 and 3). These results provide further support for accounts of revaluation based upon within-compound associations.     

Reprint of ‘The psychometric properties of the McCarron Assessment of Neuromuscular Development as a longitudinal measure with Australian youth’

The importance of considering age and sex differences in the assessment of motor performance has been largely overlooked. This study examines the psychometric properties of the US developed McCarron Assessment of Neuromuscular Development (MAND) using data from a longitudinal sample of 986 Australian youth at 10, 14 and 17 years. A key finding was the sex and age interaction of the Neuromuscular Developmental Index (NDI) (F = 121.46, p < .001). Males had a significantly lower mean NDI score at 10 years and the females had a lower score at 17 years. The factor structure differed from the US samples ( McCarron, 1997) at each age and between males and females. The sex specific analyses showed that the underlying structure was more complex for younger females. Although the MAND remains a useful test of motor performance for Australian children, further consideration is warranted regarding sex differences, the relevance of the US based normative tables and factor structures.
