Behavior analyst use of and beliefs in treatments for people with autism

With the increase in the numbers of children diagnosed with autism and scientific support solely for Applied Behavior Analysis (ABA) treatment, a proliferation of professionals have sought ABA training to provide services to this population. However, not all have been reportedly providing solely ABA services. This study surveyed Board Certified Behavior Analysts (BCBAs; N = 469) concerning their beliefs, endorsement, and use of a variety of scientifically supported and unsupported treatments for people with autism. Although not all endorsed using ABA, BCBA professionals most widely reported using ABA and ABA‐related treatments. Surprisingly, BCBAs endorsed and used all types of treatments, despite their beliefs that the treatments were difficult to implement, not cost effective, and not supported by research.

The latent structure of anxiety sensitivity--revisited

Anxiety sensitivity has been implicated as a risk factor for the development and maintenance of panic and other anxiety disorders. Although researchers have generally assumed that anxiety sensitivity is a dimensional, rather than categorical, variable, recent taxometric research has raised questions concerning the accuracy of this assumption. The present study examined the latent structure of anxiety sensitivity by applying four taxometric procedures (MAXEIG, MAXCOV, MAMBAC, and L-Mode) to data collected from two large nonclinical samples (n = 1,025 and n = 744) using two distinct measures of anxiety sensitivity (Anxiety Sensitivity Profile and Anxiety Sensitivity Index-Revised). In contrast to previous taxometric analyses of anxiety sensitivity, results of the present research provided convergent evidence for a latent anxiety sensitivity dimension. Several potential explanations for the discrepancy between these findings and those of previous research are discussed, as well as the implications of these findings for the conceptualization and measurement of anxiety sensitivity.     

Foucault’s turn from literature

This paper lays the groundwork for formulating an approach to literature which pushes Foucault’s thought in directions which he perhaps envisaged, but never pursued. However, one of the major obstacles to formulating a Foucauldian philosophy of literature is the fact that Foucault’s thought itself turned away from literature in the late 1960s. Why does literature apparently disappear from Foucault’s writings after 1969? And why does Foucault’s own re-writing of his theoretical biography elide this earlier interest in literature? In order to answer these questions we will have to find out what role literature played in his early thought. What is at stake here, is not just a better understanding of Foucault’s thought, but more importantly, the possibility of reviving one of the potential lines of flight which that thought cut short as a result of its own endless turning. Hence, my ultimate aim will be to address the question of what can be reclaimed today from Foucault’s abandoned engagement with literature.     

Cognitive processes in dissociation: an analysis of core theoretical assumptions

Dissociation is typically defined as the lack of normal integration of thoughts, feelings, and experiences into consciousness and memory. The present article critically evaluates the research literature on cognitive processes in dissociation. The authors' review indicates that dissociation is characterized by subtle deficits in neuropsychological performance (e.g., heightened distractibility). Some of the cognitive phenomena (e.g., weakened cognitive inhibition) associated with dissociation appear to be dependent on the emotional or attentional context. Contrary to a widespread assumption in the clinical literature, dissociation does not appear to be related to avoidant information processing. Rather, it is associated with an enhanced propensity toward pseudo-memories, possibly mediated by heightened levels of interrogative suggestibility, fantasy proneness, and cognitive failures. Evidence for a link between dissociation and either memory fragmentation or early trauma based on objective measures is conspicuously lacking. The authors identify a variety of methodological issues and discrepancies that make it difficult to articulate a comprehensive framework for cognitive mechanisms in dissociation. The authors conclude with a discussion of research domains (e.g., sleep-related experiences, drug-related dissociation) that promise to advance our understanding of cognition and dissociation.     

False recognition of facial expressions of emotion: causes and implications

This article examines the importance of semantic processes in the recognition of emotional expressions, through a series of three studies on false recognition. The first study found a high frequency of false recognition of prototypical expressions of emotion when participants viewed slides and video clips of nonprototypical fearful and happy expressions. The second study tested whether semantic processes caused false recognition. The authors found that participants made significantly higher error rates when asked to detect expressions that corresponded to semantic labels than when asked to detect visual stimuli. Finally, given that previous research reported that false memories are less prevalent in younger children, the third study tested whether false recognition of prototypical expressions increased with age. The authors found that 67% of eight- to nine-year-old children reported nonpresent prototypical expressions of fear in a fearful context, but only 40% of 6- to 7-year-old children did so. Taken together, these three studies demonstrate the importance of semantic processes in the detection and categorization of prototypical emotional expressions.     

Component Models for Fuzzy Data

The fuzzy perspective in statistical analysis is first illustrated with reference to the “Informational Paradigm” allowing us to deal with different types of uncertainties related to the various informational ingredients (data, model, assumptions). The fuzzy empirical data are then introduced, referring to J LR fuzzy variables as observed on I observation units. Each observation is characterized by its center and its left and right spreads (LR₁ fuzzy number) or by its left and right “centers” and its left and right spreads (LR₂ fuzzy number). Two types of component models for LR₁ and LR₂ fuzzy data are proposed. The estimation of the parameters of these models is based on a Least Squares approach, exploiting an appropriately introduced distance measure for fuzzy data. A simulation study is carried out in order to assess the efficacy of the suggested models as compared with traditional Principal Component Analysis on the centers and with existing methods for fuzzy and interval valued data. An application to real fuzzy data is finally performed. We would like to express our gratitude to the Editor, the Associate Editor, and the Referees whose comments and suggestions improved significantly the quality of the paper.     

Traumatized mothers can change their minds about their toddlers: Understanding how a novel use of videofeedback supports positive change of maternal attributions

This study explored the use of a brief experimental intervention that integrates principles of infant-parent psychotherapy, videofeedback, controlled exposure to child distress in the context of parental posttraumatic stress disorder (PTSD), and stimulation of parental reflective functioning (RF). The Clinician Assisted Videofeedback Exposure Session (CAVES) was applied to 32 interpersonal violence-exposed mothers of very young children (8-50 months) with respect to change of maternal perception of her child. While we found no significant reduction over two videotaped assessment visits with a mental health professional, we did find a significant reduction in the degree of negativity of maternal attributions towards her child following the videotaped visit focused on the CAVES (p<.01). Maternal RF, a mother's capacity to think about mental states in herself and her child, accounted for 11% of the variance in reduction of maternal negativity after accounting for baseline levels of negativity. Clinician-assisted videofeedback appears to support emotional self-regulation of mothers with violence-related PTSD. Focusing with a therapist on videofeedback of child separation distress exposes mothers to avoided mental states of helplessness and perceived loss of protection. Negative maternal attributions may mark violent trauma-associated emotion dysregulation and projected self-representations of the maltreated mother.     

The Buffering Role of Social Support Perceptions in Relation to Eating Disturbances among Women in Abusive Dating Relationships

Abuse is often associated with diminished social support networks, which typically serve to buffer individuals against stress-related outcomes, including eating disorders. The goal of the present study was to examine whether eating disturbances among women in abusive dating relationships varied as function of perceived social support. Although both physical and psychological aggression in women's (N=83) dating relationships was associated with symptomatic dieting and bulimic symptoms, only psychological aggression predicted unique variance. Although psychological aggression was directly related to eating symptoms, support from friends diminished the relation to bulimic symptoms, possibly because such support facilitated women's ability to distract themselves from their abusive situations. In contrast, perceived parental support buffered women in physically abusive relationships from disturbed eating patterns. Thus, depending on the nature of abuse women experienced, social support resources were differentially effective in buffering women from eating disturbances.
