An evaluation of in vivo desensitization and video modeling to increase compliance with dental procedures in persons with mental retardation

Fear of dental procedures deters many individuals with mental retardation from accepting dental treatment. This study was conducted to assess the effectiveness of two procedures, in vivo desensitization and video modeling, for increasing compliance with dental procedures in participants with severe or profound mental retardation. Desensitization increased compliance for all 5 participants, whereas video modeling increased compliance for only 1 of 3 participants.     

Food caching by western scrub-jays (Aphelocoma californica) is sensitive to the conditions at recovery

Western scrub-jays (Aphelocoma californica) cached perishable and nonperishable food items, which they could recover after both short and long retention intervals. When perishable items were always degraded at recovery, jays decreased the number of perishable items cached and increased their caching of nonperishable items, relative to a control group whose caches were always fresh at recovery. Jays reduced the number of nonperishable items cached, however, when highly preferred food items were degraded only after the long retention intervals. The findings are discussed in terms of the role of retrospective and prospective processes in the control of caching.     

Factor structure of the Wechsler Adult Intelligence Scale-III in schizophrenia

This report examines and compares the factor structure of the new edition of the Wechsler Adult Intelligence Scale (WAIS-III) in a sample of chronic schizophrenia and schizoaffective disorder outpatients (n = 120) and an age-matched sample of individuals drawn from the WAIS-III standardization sample (n = 200). Exploratory and confirmatory factor analyses similar to those reported by the developers of the scale suggested that a model of WAIS-III performance with correlated factors for verbal comprehension, perceptual organization, working memory, and processing speed fit the data from the schizophrenia sample as well as it fit the nonclinical comparison sample and fit the data from both samples better than alternative models.     

The Problem of Having Both a Body and a Name in the Work of Jean-Luc Marion

In this essay, and following upon both Jacques Lacan’s and Jacques Derrida’s personal struggles with fatherhood and the naming of their children, I take up what I consider to be Jean-Luc Marion’s failure to deal with the embodiment of fatherhood through an examination of patriarchal signification, or, specifically, the naming of one’s children after the father — at least insofar as Marion’s brief analysis of this symbolic act points toward his failure to think through the various potential and lived embodiments of the father. I aim to illuminate how his efforts to continue this naming of the child with the father’s name speak more directly to an idealized (“theologized”) vision of our world that need not be serviced, indeed, which we would benefit from not utilizing at all. I wish, in an autobiographical-phenomenological response to Marion, to point to other names, other relationships, and other ways of perceiving how one might be situated within our world. I follow Sara Ahmed in calling “queer” ways in which a phenomenological account of the subject’s identity are not a pretext for perpetuating a quasi-theological, patriarchal agenda.     

Linking Genetic Counseling Content to Short-Term Outcomes in Individuals at Elevated Breast Cancer Risk

Few studies have linked actual genetic counseling content to short-term outcomes. Using the Self-regulation Model, the impact of cognitive and affective content in genetic counseling on short-term outcomes was studied in individuals at elevated risk of familial breast-ovarian cancer. Surveys assessed dependent variables: distress, perceived risk, and 6 knowledge measures (Meaning of Positive Test; Meaning of Negative Test; Personal Behavior; Practitioner Knowledge; Mechanisms of Cancer Inheritance; Frequency of Inherited Cancer) measured at pre- and post-counseling. Proportion of participant cognitive and affective and counselor cognitive and affective content during sessions (using LIWC software) were predictors in regressions. Knowledge increased for 5 measures and decreased for Personal Behavior, Distress and Perceived Risk. Controlling for age and education, results were significant/marginally significant for three measures. More counselor content was associated with decreases in knowledge of Personal Behavior. More participant and less counselor affective content was associated with gains in Practitioner Knowledge. More counselor cognitive, and interaction of counselor cognitive and affective content, were associated with higher perceived risk. Genetic counselors dominate the content of counseling sessions. Therefore, their content is tied more closely to short term outcomes than participant content. A lack of patient communication in sessions may pose problems for understanding of complex concepts.

Omission Learning after Instrumental Pretraining

Hungry rats were pretrained to press two levers on a concurrent schedule for food pellets. Following either limited or extended pretraining, presentations of a sucrose solution were programmed on a random time schedule while the animals continued pressing on a concurrent schedule for food pellets. Presses on one of the levers-the omission lever-postponed deliveries of the sucrose solution scheduled to occur within a fixed period of time following the press, whereas presses on the other, control lever had no effect on the random time contingency. The animals pressed less frequently on the omission lever than on the control lever following limited pretraining but failed to discriminate between the two levers following extended pretraining. The insensitivity to the omission contingency produced by extended pretraining was due to either the number of presses performed during the initial training or the number of reinforced presses, rather than the number of reinforcers received. Finally, the insensitivity of performance on the omission lever to sucrose devaluation suggests that adaptation tothis negative contingency was mediated by an inhibitory stimulus-response association.
