Anxiety is one of the most basic human emotions and occurs in every person at some time, most often when someone is apprehensive about uncertain outcomes of an event or set of circumstances. Anxiety can serve an adaptive function, however, and is also a marker for typical development. In the school setting, anxiety is experienced often by students…

Uses a heuristic example, data from K. Holzinger and F. Swineford (1939) to illustrate the "holdout" method to assess the generalizability of results in multiple regression. Regression weighted from one data subset are used to compare estimated dependent variable scores from the opposite subset. (SLD)

Pigeons were exposed to a random relation between a conditioned stimulus (CS) and an unconditioned stimulus (US) under the signaled random procedure. All US presentations that were unpaired with the CS were preceded by a second cue, a cover stimulus. Consistent with prior studies, the signaled random procedure supported responding during the CS;…

The effects of reinforcement and extinction on response variability and stimulus generalization in the punching and kicking techniques of 2 martial arts students were evaluated across drill and sparring conditions. During both conditions, the students were asked to demonstrate different techniques in response to an instructor's punching attack.…

Meta-analysis procedures were employed to synthesize findings of research for improving reading comprehension of students with learning disabilities published in the decade following previous meta-analytic investigations. Forty studies, published between 1995 and 2006, were identified and coded. Nearly 2,000 students served as participants.…

In this monograph, the authors have brought the findings of the English and Romanian Adoptee (ERA) study up to age 15 years and, in so doing, have focused especially on the question of whether there are deprivation-specific psychological patterns (DSPs) that differ meaningfully from other forms of psychopathology. For this purpose, their main…

Statistical regularities in language have been examined for new insight to the language acquisition process. This line of study has aided theory advancement, but it also has raised methodological concerns about the applicability of corpora data to child populations. One issue is whether it is appropriate to extend the regularities observed in the…

What does it mean to be a Muslim woman? Even a basic understanding could help to dispel generalizations and stereotypes, especially in the context of education. With the controversies related to the wearing of the headscarf in educational institutions, to the general assumption that Muslim women are disempowered, this is even more important for…

Response variability, a fundamental characteristic of behavior, may be in some cases an induced effect of reinforcement schedules. Research on schedule-induced response variability has shown that continuous reinforcement results in less variability than intermittent reinforcement schedules. Studies on the effects of intermittency of reinforcement,…

Reliability generalization studies have provided estimates of the mean reliability coefficients and examined factors that explain the variability in the reliability estimates across studies for many different tests and measures. Different authors have used different data analyses to do such meta-analyses, and little research has addressed whether…

The advent of telemetric devices that sample data extensively over time has facilitated single subject or idiographic research to intensively study a single person over time. One of the challenges of idiographic research is combining single subject results to determine generalizability across subjects. This article demonstrates the first…

"Self-awareness" is a specific type of autoclitic discriminative behavior and inferential generalization to similar performances exhibited by other people. Brain imaging findings take on special importance within behavior analysis when they indicate that dysfunctions in these areas are related to differential effects of our interventions, with…

We examined the influence of prior exposure to specific animal properties on 15-month-old infants' inductive generalization. Using picture books, 29 infants were trained on properties linked in a congruent or incongruent manner with four animal categories. A generalized imitation task was then administered to assess patterns of property extension…

Young children tend to generalize novel names for novel solid objects by similarity in shape, a phenomenon dubbed "the shape bias". We believe that the critical insights needed to explain the shape bias in particular, and cognitive development more generally, come from Dynamic Systems Theory. We present two examples of recent work focusing on the…

Use of spreadsheets in a beginning algebra course was investigated mainly with regard to their potential to promote generalization of patterns. Less is known about their use in promoting understanding and learning of transformational activities. The overall purpose of this paper is to consider the conceptual aspects of learning a transformational…
