THE ROLE OF INDEPENDENT VARIABLE INTEGRITY IN THE BEHAVIORAL MANAGEMENT OF TOURETTE SYNDROME

We examined the effects of self-monitoring, dissimilar response practice, and competing response practice on the tics of two preadolescent males with Tourette Syndrome. Tic frequencies were assessed using an alternating treatments design over the course of approximately 1 month. The data indicate that neither of the participants’ tics changed as a result of the interventions. Upon examination of independent variable integrity data, we noticed that the participants were not implementing the treatments as instructed. The results are discussed in the context of improving the research methodology in this area, particularly with respect to independent variable integrity measures.     

Why does working memory span predict complex cognition? Testing the strategy affordance hypothesis

We introduce and empirically evaluate the strategy affordance hypothesis, which holds that individual differences in strategy use will mediate the relationship between performances on a working memory (WM) span task and another cognitive task only when the same strategies are afforded by both tasks. One hundred forty-eight participants completed basic memory tasks and verbal span tasks that afford the same strategies, such as imagery and sentence generation, and completed reading comprehension tasks that afford different ones, such as self-questioning and summarization. Effective strategy use on WM span tasks accounted for variance in the span-memory relationship, but not for the span-comprehension relationship, supporting the strategy affordance hypothesis. Strategy use mediated the span-cognition relationship only when both tasks afforded the same strategies.     

When Anxiety Symptoms Masquerade as Medical Symptoms: What Medical Specialists Know about Panic Disorder and Available Psychological Treatments

Under-recognition of somatic symptoms associated with panic in primary care settings results in unnecessary and costly diagnostic procedures and inappropriate referrals to cardiologists, gastroenterologists, and neurologists. In the current study specialists’ knowledge regarding the nature and treatment of panic were examined. One-hundred and fourteen specialists completed a questionnaire assessing their knowledge about panic attacks, including their perceptions of psychologists’ role in treating panic. Respondents answered 51% of knowledge items correctly. Although most knew the definition of a panic attack, they knew less about clinical features of panic and its treatment. Specifically, whereas 97.4% believed medication effectively relieves panic symptoms, only 32.5% knew that cognitive-behavioral therapy (CBT) is a first-line treatment. Only 6% reported knowing how to implement CBT, and only 56.1% recognized that psychologists could effectively treat panic. These findings demonstrate significant gaps in specialists’ knowledge about panic and the need to enhance physician knowledge about panic attacks and their treatment.     

Testing the concept of goodness of fit in early intervention

While the conceptual and clinical utility of the goodness of fit concept has been documented extensively, the number of specific empirical tests of the concept has been limited. In this study, the concept was applied in the conceptualization and analysis of early intervention efforts. The major question examined was the extent to which the goodness of fit of child, maternal, and support variables discriminated good and poor adaptation of the mother as measured by the quality and appropriateness of care giving involvement with her handicapped child. Findings indicated that an index of maternal and child characteristics and measures of maternal locus of control, child temperament, and social support collectively contributed to the correct classification of 77% of mothers in high vs. low involvement groups. Locus of control and the maternal/child index accounted for 25% of the variance in caregiver involvement. The findings illustrate the applicability of the goodness of fit concept and provide support for efforts focused on maximizing the fit of the child, family, and variables in early intervention.     

A new approach for training infant intervention specialists

This paper describes a new approach to training infant specialists. A joint Master's degree program, based in graduate schools of public health and education, emphasizes cross-disciplinary coursework in maternal and child health and special education. The program emphasizes the importance of forging crucial linkages among the different disciplines and agencies that care for handicapped and at-risk infants. The program emphasizes improved skills in assessing, planning, and intervening on behalf of infants at risk for developmental delays or with severe or multiple handicaps; the ability to work with families; and the ability to develop and appraise community resources.     

Understanding Information Selection and Encoding from a Dynamic,Energy Saving,Evolved, Embodied,Embedded Perspective

This article uses the Dynamic Human Centric Communication Systems Theory to reconceptualize 4 selected attributes of attention from a human‐centric point of view. Information is defined with respect to its relationship in the environment to the human in terms of time and space. The 4 attributes considered are stability, imminence, motivational relevance, and task relevance. An experiment was conducted in which encoding was assessed using a signal detection analysis of a change detection task. Results supported the prediction that story and motivational relevance would have opposite effects on the encoding of stable information as a function of imminence. Differences in memory predictions made by traditional theoretical approaches and the DHCCST are discussed in light of the results of the experiment.
