Although behavior analysis relies primarily on visual inspection for interpreting data, previous research shows that the method of display can influence the judgments. In the current study, 26 Board-Certified Behavior Analysts reviewed two data sets displayed on each of three methods--equal-interval graphs, tables, and Standard Celeration…

By balancing the spacing effect against the effects of recency and frequency, this paper explains how practice may be scheduled to maximize learning and retention. In an experiment, an optimized condition using an algorithm determined with this method was compared with other conditions. The optimized condition showed significant benefits with…

This research develops and tests a procedure for interpreting individuals' responses in multiscale career assessments, using the Career Decision-Making Difficulties Questionnaire (CDDQ). In Study 1, criteria for ascertaining the credibility of responses were developed, based on the judgments of 39 career-counseling experts. In Study 2, the…

Strong evidence exists for the efficacy of behavior analytic approaches with children on the autism spectrum (Carr & Firth, 2005; Weiss 2001, 2005). Many early childhood intervention studies report outcomes based on pre-school populations (Smith, 1999; Casto & Mastropieri, 1986) while outcome studies for younger populations are scarcer. We…

Few studies have examined predictors of weight regain after significant weight losses. This prospective study examined behavioral and psychological predictors of weight regain in 261 successful weight losers who completed an 18-month trial of weight regain prevention that compared a control condition with self-regulation interventions delivered…

This study examined the fractional graph area (FGA), the proportion of page space used to display statistical graphics, in 11 behavioral journals and places behavior analysis on a continuum with other natural, mathematical, and social science disciplines. The composite FGA of all 11 journals puts behavior analysis within the range of the social…

This study investigated social knowledge in school-age children, aged 8-12 years, with and without language impairment (LI and TD groups). A hypothetical peer conflict task was administered to examine the relationship among prosocial responses and parent/teacher ratings of children's social behaviours. Stimuli included 12 hypothetical peer…

This article proposes a multilevel modeling approach to study the general and specific attitudes formed in human learning behavior. Based on the premises of activity theory, it conceptualizes the unit of analysis for attitude measurement as a scalable and evolving activity system rather than a single action. Measurement issues related to this…

Some children with autism demonstrate poor nonword repetition--a deficit considered to be a psycholinguistic marker of specific language impairment (SLI). The present study examined whether there is an SLI subtype among children with autism. We compared the language abilities of children with SLI (n = 34, M age = 11;10 S.D. = 2;3), and children…

The number of children with autism served in early intervention or the public school system appears to be growing at an alarming rate. This article provides a basis for understanding this dramatic increase. In addition, the authors present a brief overview of the characteristics of autism, research on early behavioral indicators of infants and…

A study examined a series of seven experiments conducted in order to identify more precisely the hierarchical structure of the concept emotion, which presumably extended from superordinate to basic and finally subordinate levels. Subjects, 1,052 persons in all, participated in any of seven different experiments: (1) listing basic level categories…

Author's aim in this article was to present humanistic or "third-force" psychology as a perspective from which to consider political events and the way we study them in the social sciences. (Author/RK)

Behavior analysis has matured as a discipline such that there are now over a dozen peer-reviewed journals devoted exclusively to its subject matter. In recent years, researchers have published with increasing frequency a number of bibliometric analyses in which journal content has been quantified and used as an index of research and publication…

The study reported here evaluates the effectiveness of performing psychotherapy by means of written communication between client and psychotherapist--a technique that could make assistance available to individuals who are isolated from traditional methods of psychological treatment by psychological or physical barriers.

This study was designed to determine whether infants actually play with crib toys, and whether the toys affect the duration or onset of sleep. (CS)
