Resistance to extinction: contingency termination and generalization decrement

We present an algebraic model of resistance to extinction that is consistent with research on resistance to change. The model assumes that response strength is a power function of reinforcer rate and that extinction involves two additive, decremental processes: (1) the termination of the reinforcement contingency and (2) generalization decrement resulting from reinforcer omission. The model was supported by three experiments. In Experiment 1, 4 pigeons were trained on two-component multiple variable-interval (VI) 60-sec, VI 240-sec schedules. In two conditions, resistance to change was tested by terminating the response-reinforcer contingency and presenting response-independent reinforcers at the same rate as in training. In two further conditions, resistance to change was tested by prefeeding and by extinction. In Experiment 2, 6 pigeons were trained on two-component multiple VI 150-sec schedules with 8-sec or 2-sec reinforcers, and resistance to change was tested by terminating the response-reinforcer contingency in three conditions. In two of those conditions, brief delays were interposed between responses and response-independent reinforcers. In both Experiments 1 and 2, response rate was more resistant to change in the richer component, except for extinction in Experiment 1. In Experiment 3, 8 pigeons were trained on multiple VI 30-sec, VI 120-sec schedules. During extinction, half of the presentations of each component were accompanied by a novel stimulus to produce generalization decrement. The extinction data of Experiments 1 and 3 were well described by our model. The value of the exponent relating response strength and reinforcement was similar in all three experiments.     

Behavior Problems of African American Boys and Girls Attending Head Start Programs in Violent Neighborhoods

This article examined behavior problems exhibited by African American children attending Head Start centers in violent neighborhoods. Children's scores on the Child Behavior Checklist (CBCL)/parent form were compared to the mean scores for the CBCL's non-clinical standardization sample on the internalizing, externalizing, and total problem scales. The Head Start children's scores were not significantly different from the standardization sample on the internalizing scale, but both boys and girls in the study sample had significantly higher scores on the externalizing and total problem scales than their respective gender group in the standardization sample. There were no significant differences in the T scores of boys and girls in this study on any of the three behavior problem scales. The study also examined percentages of boys and girls with behavior problems in the more severe ranges. Higher percentages of boys than girls had severe internalizing problems, while higher percentages of girls than boys had severe externalizing problems. Analyses of total behavior problem scores revealed no significant differences between boys and girls in the severe ranges. Implications of findings for research, practice, and policy are discussed within the sociocultural contexts of the families and communities in the study.     

Using order to reason about negative numbers: the case of Violet

This case study illustrates how a 2nd-grade child, Violet, used an ordinal view of number to reason about positive and negative integers and arithmetic involving integers. Violet’s ordinal view of number facilitated her ability to reason about and correctly solve some integer-related problems and constrained her solutions to others. We demonstrate how Violet’s thinking evolved over time while she extended the properties of whole numbers and addition and subtraction to the integers. Using this case study as a basis, we propose a series of developmental milestones that build toward one’s understanding of integers and integer arithmetic in an order-based way. We believe that understanding Violet’s order-based reasoning can help us listen to other children.     

Theoretical Development,Factorial Validity,and Reliability of the Online Graduate Mentoring Scale

In this study, we sought to confirm the theoretical framework underlying an Online Graduate Mentoring Scale by establishing the scale’s factorial validity and reliability. Analysis of data received from doctoral students and alumni/ae of the College of Education of one large, online, accredited university reduced the initial theoretical framework from seven to six attributes, and resulted in a revision of the scale. Further research is needed to test the theoretical framework with other relevant populations and to refine the scale itself by reducing skewness and attaining item balance.
