Conditioned reinforcement and response strength

Stimuli associated with primary reinforcers appear themselves to acquire the capacity to strengthen behavior. This paper reviews research on the strengthening effects of conditioned reinforcers within the context of contemporary quantitative choice theories and behavioral momentum theory. Based partially on the finding that variations in parameters of conditioned reinforcement appear not to affect response strength as measured by resistance to change, long-standing assertions that conditioned reinforcers do not strengthen behavior in a reinforcement-like fashion are considered. A signposts or means-to-an-end account is explored and appears to provide a plausible alternative interpretation of the effects of stimuli associated with primary reinforcers. Related suggestions that primary reinforcers also might not have their effects via a strengthening process are explored and found to be worthy of serious consideration.     

Effectiveness of cognitive behavioral therapy on the signs,symptoms and clinical consequences of premature ejaculation

The purpose of this research was to assess the effectiveness of cognitive behavioral therapy (CBT) on the signs, symptoms, and clinical‐sexual consequences of premature ejaculation, including sexual esteem, sexual anxiety, sexual depression, sexual fear, and sexual satisfaction of patients and their wives. Fifteen patients with premature ejaculation were selected and received cognitive behavioral therapy of eight to 12 sessions. Finally, the data collected from 12 patients were analyzed using paired t‐tests. The results of the analysis showed that all of the variables changed after the treatment. All of the changes were statistically significant with a tendency towards improvement. CBT can be a more popular and effective treatment provided to patients suffering from premature ejaculation.     

Handedness and Hemispheric Asymmetry in the Control Of Movements

This study investigated the influence of hemispheric specialization of function on the motor performance of the hands. Right-handed (n=17), ambidextral (n=21), and ambisinistral (n=12) subjects performed Fitts' (1954) reciprocal tapping task under two conditions with each hand. Conditions had the same index of difficulty but differed in movement precision. The left hand of righthanders was superior in the condition requiring the greatest amount of preprogramming. Conversely, the right hand was not superior in the condition having the greatest demand for feedback control. For ambidextrals, left-hand superiority in the relatively preprogrammed condition was also revealed. Ambisinistrals showed no significant difference between conditions with either hand. The results partially support the hypothesis that the motor performance of the hands mirrors the dominant processing mode of their contralateral hemisphere. Failure to find supportive evidence in ambisinistrals is consistent with the contention that they lack hemispheric specialization of function.     

Relations Between Parenting Behavior and SES in a Clinical Sample: Validity of SES Measures

Two common methods of measuring socioeconomic status (SES) were examined in relation to observed parenting behaviors in a clinical sample of 89 mothers of 3- to 6-year-olds referred for treatment of oppositional defiant disorder. Families were 74% Caucasian, 9% African American, 5% Hispanic, 1% Asian, and 11% Biracial. Most children were male (75%). Parenting behaviors were measured with the Dyadic Parent–Child Interaction Coding System (DPICS) categories of prosocial talk and negative talk. Analyses were conducted with SES measured in two ways: (a) the Hollingshead Four-Factor Index of Social Status (HI) was correlated with parenting behaviors; and (b) family income, parent education (5 categories), and parent occupation (5 categories) were used to predict parent behavior. SES was significantly positively related to maternal prosocial talk. When SES was operationalized as income, occupation, and education, the model predicted three times more variance in maternal prosocial talk than the HI alone. SES was not related to maternal negative talk by either measure of SES.     

Development and Validation of the Children's Assertiveness Inventory

The development and validation of the Children's Assertiveness Inventory are reported. Psychometric properties of the scale are detailed for the normal samples of grade school children and one sample of socially withdrawn children. Initial analyses indicate that the scale possesses high test-retest reliability and acceptable stability over time. Further, it adequately discriminates between normal and withdrawn samples, has acceptable convergent and discriminant validity, and possesses a meaningful factor structure. The potential research and clinical utility of the scale is discussed, and important social and developmental issues affecting the expression of assertiveness in children are addressed.     

Evaluating the Acceptability of Four Versions of a Child Sexual Abuse Prevention Program

Fifty-nine college students used a modified version of the Treatment Evaluation Inventory-Short Form to evaluate the acceptability of four versions of a sexual abuse prevention program for 10-year-old children. The four versions include an information-based training approach or a behavioral skills training (BST) approach with a focus on strangers or known individuals as perpetrators of sexual abuse. A significant effect was found for both training method and type of perpetrator, with information-based approaches involving strangers as perpetrators rated the most acceptable. These results suggest that college students were most comfortable with sexual abuse prevention training programs for 10-year-olds when the programs did not involve an active rehearsal component and when the program focused on abuse perpetrated by a stranger rather than a known individual.     

Cognitive Behavioral Principles Within Group Mentoring: A Randomized Pilot Study

This study evaluated the effectiveness of a group mentoring program that included components of empirically supported mentoring and cognitive behavioral techniques for children served at a community mental health center. Eighty-six 8- to 12-year-old children were randomly assigned to either group mentoring or a wait-list control group. Group mentoring significantly increased children's reported social problem-solving skills and decreased parent-reported child externalizing and internalizing behavior problems after controlling for other concurrent mental health services. Attrition from the group mentoring program was notably low (7%) for children. The integration of a cognitive behavioral group mentoring program into children's existing community mental health services may result in additional reductions in externalizing and internalizing behavior problems.

Behavioral Skills Training With Teachers: Booster Training for Improved Maintenance

Behavioral skills training (BST) has been employed within many different populations for the reduction of problem behaviors and acquisition of new skills; however, these changes have not always maintained over time. This study evaluated the effects of a booster training for re-establishing the classroom management proficiencies that teachers had acquired previously, but had declined over a 12-month period. The single-subject experimental results showed the booster training to be effective in re-establishing teacher performance of skills as measured by both analogue role-play and in situ postassessments within the classroom. These findings suggest that a booster training utilizing BST may be an important strategy for maintaining skill performance over time.
