Translating the QABF to Spanish with an Eye Toward Reliability and Validity

We developed a Spanish‐language version of the Questions About Behavioral Function (QABF) utilizing a forward‐adaptation and back‐adaptation translation process. Subsequently, we administered the assessment with 80 bilingual participants to assess the reliability and validity of the instrument. Results demonstrated that the Spanish version of the QABF was both reliable (i.e., was internally consistent) and valid (i.e., identified the correct function). Implications and future research are discussed. Copyright © 2014 John Wiley & Sons, Ltd.     

A misinterpreted psychoanalyst: Herbert Silberer and his theory of symbol-formation

The primary aim of this article is to give a more detailed exposition of the cultural, personal, and theoretical contexts in which the Viennese psychoanalyst, Herbert Silberer's theories were born. When assessing the broader picture that this approach offers, it can be concluded that Silberer was an innovative thinker who inspired several of his contemporaries. Recognized in many respects by the society and scholars of this time, he represented quite a different viewpoint that was significantly influenced by several forms of Western esoteric thinking. Yet his main aim was to contribute to the field of psychoanalysis and develop a theory in which rationalistic psychoanalytic interpretations were combined with nonreductive approaches to mystical experiences. Silberer's name is frequently mentioned in a specific context in which his tragic suicide is emphasized rather than his innovations. Upon evaluating the materials recording Silberer's private life, it seems very likely that his suicide was not triggered by the criticism of Freud alone. Silberer's family affairs, his relationship with his father, and his financial and professional struggles could have all contributed to his tragic decision. This paper contends that Silberer's oeuvre deserves greater attention and must be evaluated based upon its own merit.     

Event-related fMRI of category learning: differences in classification and feedback networks

Eighteen healthy young adults underwent event-related (ER) functional magnetic resonance imaging (fMRI) of the brain while performing a visual category learning task. The specific category learning task required subjects to extract the rules that guide classification of quasi-random patterns of dots into categories. Following each classification choice, visual feedback was presented. The average hemodynamic response was calculated across the eighteen subjects to identify the separate networks associated with both classification and feedback. Random-effects analyses identified the different networks implicated during the classification and feedback phases of each trial. The regions included prefrontal cortex, frontal eye fields, supplementary motor and eye fields, thalamus, caudate, superior and inferior parietal lobules, and areas within visual cortex. The differences between classification and feedback were identified as (i) overall higher volumes and signal intensities during classification as compared to feedback, (ii) involvement of the thalamus and superior parietal regions during the classification phase of each trial, and (iii) differential involvement of the caudate head during feedback. The effects of learning were then evaluated for both classification and feedback. Early in learning, subjects showed increased activation in the hippocampal regions during classification and activation in the heads of the caudate nuclei during the corresponding feedback phases. The findings suggest that early stages of prototype-distortion learning are characterized by networks previously associated with strategies of explicit memory and hypothesis testing. However as learning progresses the networks change. This finding suggests that the cognitive strategies also change during prototype-distortion learning.     

A paradoxical effect of presession attention on stereotypy: antecedent attention as an establishing, not an abolishing, operation

Previous studies have shown that presession attention for problem behavior can serve as an abolishing operation when attention functions as a positive reinforcer. In the current study, we show that the stereotypy of a child with severe disabilities was undifferentiated during standard analogue functional analysis conditions. However, when noncontingent presession attention was provided, stereotypy occurred for social attention as a positive reinforcer, suggesting that the antecedent manipulation functioned as an establishing operation.     

The effect of contingent reinforcement on target variables in outpatient psychotherapy for depression: a successful and unsuccessful case using functional analytic psychotherapy

The current study investigated a behavior-analytic treatment, functional analytic psychotherapy (FAP), for outpatient depression utilizing two single-subject A/A+B designs. The baseline condition was cognitive behavioral therapy. Results demonstrated treatment success in 1 client after the addition of FAP and treatment failure in the 2nd. This study highlights the challenges in measuring treatment progress and outcome idiographically in this population.     

Further examination of discriminated functional communication

One child with developmental disabilities was taught to mand for attention by saying "excuse me." Treatment effects were extended to multiple training contexts by teaching the participant to attend to naturally occurring discriminative stimuli through differential reinforcement of communication during periods of the experimenter's nonbusy activities (e.g., reading a magazine). Results are discussed in terms of future research on the generalization and maintenance of functional communication in the natural environment.     

Functional analysis and treatment of aggression maintained by preferred conversational topics

After an initial functional analysis of a participant's aggression showed unclear outcomes, we conducted preference and reinforcer assessments to identify preferred forms of attention that may maintain problem behavior. Next, we conducted an extended functional analysis that included a modified attention condition. Results showed that the participant's aggression was maintained by access to preferred conversational topics. A function-based intervention decreased aggression and increased an appropriate communicative response.
