In this article, we describe a test of the active time model for concurrent variable interval (VI) choice. The active time model (ATM) suggests that the time since the most recent response is one of the variables controlling choice in concurrent VI VI schedules of reinforcement. In our experiment, pigeons were trained in a multiple concurrent…

Fjellstedt and Sulzer-Azaroff (1973) used differential reinforcement of short latencies to decrease a child's latency to comply with instructions. We replicated this contingency with a young man diagnosed with Asperger syndrome across two tasks (question answering and math problem solving). We added a differential reinforcement contingency to…

The author argues that the field of behavior intervention has two subject matters that are distinct in several ways. Each is derived from, and contributes to, the foundation science and epistemology associated with behavior selection. The differences that the author wants to describe occurred to him as he sought to identify which of two Spanish…

We tested the effect of a Rotated Protocol Immersion package on the emergence of observing responses as prerequisites for more complex verbal developmental capabilities. Three elementary aged students between the ages of 6 and 7 participated. They were diagnosed with autism spectrum disabilities. The treatment condition consisted of total…

Major findings were that: contingent reinforcement was effective in altering behavior; instructions did not augment the efficacy of contingent reinforcement; noncontingent reinforcement was effective for nondeviant students who were told that the reinforcement was actually contingent; and contingent reinforcement led to greater generalization than…

A method of studying attachment behavior in infants was devised using time series and time sequence analyses. Time series analysis refers to relationships between events coded over adjacent fixed-time units. Time sequence analysis refers to the distribution of exact times at which particular events happen. Using these techniques, multivariate…

This study used behavioral measures of family interaction to examine four traditional explanatory models for the influence of parents on their children's self-esteem. The four models examined were: (1) identification/modeling, (2) directiveness, (3) reinforcement, and (4) warmth/involvement. A total of 98 fourth- and fifth-grade girls and boys…

These 11 behavior observation schedules were developed to serve as a source of data for evaluation experimental variations in instructional procedures and classroom organization, and for monitoring changes in teacher, teacher aide, and child behaviors. (MS)
