Human classical aversion conditioning: Nausea versus electric shock in the reduction of target beverage consumption

Two experiments were conducted to investigate the effectiveness of the nausea-pro-ducing Pseudo-Coriolis Effect (PCE) in conditioning aversions to beverage consumption. The first experiment assessed the effectiveness of this procedure while controlling for demand characteristics. The second experiment compared this procedure with electrical aversion conditioning. This study demonstrates the effectiveness and relative superiority of the PCE in classical aversion conditioning. Consideration is given to the parameters and potential applications of this procedure     

Waveform moment analysis: An ASYST program for topographical analyses of nonnegative bounded waveforms

The moments of a nonnegative bounded waveform (e.g., bounded probability density functions or responses that can be expressed as bounded probability density functions) provide the basis for characterizing the waveform. Traditionally, only the lower-order moments (k ≤ 4) have been utilized in deriving topographical indices of these waveforms. Recent advances in waveform moment analysis, however, have made it possible to derive comprehensive and interpretable indices of complex nonnegative bounded waveforms by utilizing both lower-order and higher-order moments. Waveform moment analysis is reviewed briefly, and a flexible and efficient computer program is presented for conducting waveform moment analyses.

Expectancy Accessibility and the Influence of Outcome Expectancies on Adolescent Smokeless Tobacco Use

This study investigated the moderating influence of expectancy accessibility on the relation between outcome expectancies and drug use intentions. Specifically, it was hypothesized that expectancies made temporarily more accessible would predict smokeless tobacco intentions to a greater degree than would less accessible expectancies. In addition, it was anticipated that expectancies regarding positive outcomes of smokeless tobacco use would be better predictors of intention than would expectancies about negative outcomes. Results partially supported the accessibility hypothesis, but this effect occurred for positive outcome expectancies only. In addition, the anticipated prepotency of positive over negative expectancies in predicting drug use intentions was strongly supported. These findings are consistent with theories of problem behavior which differentiate between positive and negative outcome expectancies and which postulate that accessibility of expectancies plays an important role in expectancy-behavior relations.     

The Experience of Crisis in Families of Individuals with Autism Spectrum Disorder Across the Lifespan

It is well-established that parents of individuals with autism spectrum disorder (ASD) experience significant stress in their caregiving role, and research findings indicate that chronic stressors can act as a precipitant to crisis. In the present study, we examined the experience of crisis in families of individuals with ASD from early childhood to adulthood. One hundred and fifty-seven comments provided by family members in response to an online survey were coded using grounded theory methods. We explored three components of crisis drawn from the comments: antecedents (precipitating events and the context of crisis), behaviors (the nature of crisis), and consequences (outcomes and reactions to crisis). Similarities and differences in the crisis experiences among varying age groups are discussed, as well as implications for practice and future research.
