The Moderating Effect of Anxiety on Development in Atypically Developing Toddlers

In typically developing children, researchers have found that anxiety disorders are associated with poorer intellectual abilities (Davis et al. Journal of Psychopathology and Behavioral Assessment 30:43–51, 2008). The aim of the current study was to examine the impact anxiety symptoms had on the developmental quotients of toddlers. A total of 170 toddlers ranging in age from 17 to 37 months were selected for inclusion in this study, all of whom were at risk for or had a developmental delay. Two factors indicative of behavioral symptoms of anxiety from the Baby and Infant Screen for Children with aUtIsm Traits-Part2 were utilized as the independent variables and the total developmental quotient from the Battelle Developmental Inventory, 2nd Edition was utilized for the dependent variable. Examination of results revealed that atypically developing toddlers with symptoms of anxiety had significantly lower developmental quotients when compared to toddlers without any anxiety symptoms. A discussion of the implications and limitations of this study are included.     

Independence training vs modeling procedures for teaching phone conversation skills to the mentally retarded

Forty-five mildly mentally retarded adults were assessed for deficits in telephone conversational skills. They were ranked on the basis of their pretest scores and matched into triplets on skill level. One member from each of these groups was then randomly assigned to either a no-treatment control group, a modeling condition or independence training—a treatment that incorporated social reinforcement, instructions, performance feedback, modeling, shaping by successive approximations and self-monitoring and evaluation. For the two latter conditions, treatment was provided three times weekly for 2 months in group sessions (N = 5) of 1 hr duration. The dependent variable, conversational skills of subjects was assessed at pretest, posttest and at a 3-month follow-up based on verbal responses that subjects made to nine questions asked by an experimenter and related social responses during a phone call. Independence training proved to be significantly more effective than the other two experimental conditions at posttest and follow-up. In addition, modeling proved to be significantly more effective than the no-treatment controls at both of these assessment points.     

MOTHERS AS EFFECTIVE THERAPISTS FOR AUTISTIC CHILDREN'S PHOBIAS

Two autistic children were treated for specific fears. A three-component participant modeling procedure was implemented within a multiple baseline design across subjects. Children were exposed gradually to fearful situations, with mothers serving as therapists and reinforcers. Dependent measures were (a) number of approach steps completed, (b) frequency of verbalizations and vocalizations of fear, and (c) overall appearance of fear. Following treatment, the children functioned effectively in previously fearful situations without verbalizations or appearance of fear. Five-month and 1-year follow-up assessments with 1 child showed maintenance of treatment effects.     

Training visual efficiency in myopic persons

Twenty-four myopic college students were paired into groups based on degree of visual impairment using the Snellen Illiterate E. One member of each pair was then assigned to a no-treatment control group or a training program composed of fading, social reinforcement and performance feedback. Results on trained stimuli (Snellen Illiterate E) were significantly different across experimental conditions at posttest while differences across experimental conditions at posttest on untrained stimuli (Snellen Letters) were not significant. The implications of these data are discussed with reference to areas for additional research.     

Independence training as a method of enhancing self-help skills acquisition of the mentally retarded

This study examined the effectiveness of independence training which involved using social reinforcement, information feedback, modeling and evaluation of self and others in teaching showering behavior to institutionalized mentally retarded adults. A treatment and a non-treatment group of 36 subjects each were used to assess training and maintenance of the target behavior. Analysis of results showed that treatment and no-treatment groups did not differ on baseline scores. However, residents in the treatment group performed significantly better than no-treatment subjects on post-test and three-month follow-up. Staff were of the opinion at post-test that treatment was perceived to be acceptable and nonpunitive.     

Internal control and success orientation in a token economy for emotionally disturbed adolescents.

Forty-one emotionally disturbed adolescents were tested at each of three token economy levels on Rotter's Internal-External Locus of Control Scale and Guevar's Success-Failure Inventory. Delay of reinforcement (immediate, daily, weekly) was the primary differentiation between levels. One-way analyses of variance indicated a change across levels in the direction of more perceived internal control of behavior (p less than .025) and a greater success orientation (p less than .005). Change scores were not correlated with length of time in the program. Results suggest that the token economy as an external source of control is not necessarily incompatible with increasing patient expectancies of present and future control of the environment.
