Behavioral rehabilitation of functional alexia

A 10-year-old boy with a functional reading deficit (i.e. functional alexia) was successfully treated with hospital based escape/avoidance procedures. A multiple baseline design was used to evaluate the effectiveness of treatment. Generalization of treatment effects across individuals, settings and time was demonstrated. Extension of these procedures to other functional deficits is discussed.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/26688/1/0000235.pd

Brief Experimental Analysis of Spanish Reading Fluency: An Exploratory Evaluation

Brief experimental analyses of reading fluency are useful for identifying effective interventions for improving reading fluency. The current study extends previous research by conducting an exploratory evaluation of brief experimental analyses of reading fluency for Spanish reading. A 10-year old Hispanic male presented with reading fluency deficits for English and Spanish reading. Brief experimental analyses of English and Spanish reading identified distinct interventions for each which increased oral reading fluency. Intervention procedures evaluated during brief experimental analyses included listening passage preview, repeated readings, and reward. Replication of analyses was conducted to examine changes in instructional need over time. For English reading, the intervention identified during the initial analysis (i.e., listening passage preview with repeated readings) was identified as the most effective when the analysis was replicated. For Spanish reading, listening passage preview was identified as the most effective intervention during the initial analysis, while repeated readings was identified as most effective when the analysis was replicated. Results are discussed in terms of future research given the exploratory nature of the current study. © Springer Science+Business Media, Inc. 2007

Psychological and psychiatric issues in urinary and fecal incontinence

Purpose: We provide an overview of the psychological and psychiatric aspects of nocturnal enuresis, urinary and fecal incontinence. Clinical behavioral disorders and subclinical psychological symptoms are reviewed. Aspects of screening, assessment, counseling and in severe cases treatment are outlined, and recommendations are formulated. Materials and Methods: Relevant publications on psychological and psychiatric aspects are reviewed. The recommendations passed several rounds of consensus finding, and were circulated among International Children's Continence Society members and external experts. Results: In addition to subclinical effects on self-esteem, quality of life and distress, the rate of comorbid clinical behavioral disorders is increased. In fact, 20% to 30% of children with nocturnal enuresis, 20% to 40% with daytime urinary incontinence and 30% to 50% with fecal incontinence fulfill the criteria for ICD-10 or Diagnostic and Statistical Manual of Mental Disorders IV psychiatric disorders. These concomitant disturbances require assessment and counseling, and in severe cases treatment. They have a negative effect on compliance and outcome if not addressed and left untreated. Conclusions: Because the comorbidity rate is high, screening for psychological symptoms is recommended for all children in all settings with enuresis and/or daytime urinary and/or fecal incontinence. Standardized, validated questionnaires are recommended. In addition to clinical observation and history, a short screening questionnaire can be used as a first step. If problem behaviors are present a longer broadband questionnaire is recommended. If problem items in the clinical range are noted, a full child psychiatric or psychological assessment is recommended

Stimulus stringing by pigeons

Pigeons were trained to peck one, two, three, and then four colors in a predetermined sequence from a five-key array where, over trials, each color appeared equally often in each position of the array. Incorrect pecks resulted in a buzzer and trial termination, with the same array presented for the next trial. Correct pecks produced feedback and correct strings could produce food. All subjects performed at a high level of accuracy with no difference at asymptote between a continuous and a mixed spectral sequence as the required order. Transfer to a new set of arrays had little effect on accuracy. Errors forward in the sequence had the highest probability, followed by repeat errors, backward errors, and dark-key errors. Some arrays had a higher level of accuracy than others but a corresponding systematic variable could not be identified
