Argues that the key distinction of a situated approach to studying intelligent behavior is not the method used but the focus of the investigation, specifically the unit of analysis. Discusses contemporary approaches to assessment, collaborative problem solving as an assessment context, situated assessment, intentional dynamics, and interaction as…

Identifies four dominant strands in the recent literature on adults and children developing play together: socio-cultural, adversarial, child development, and nomad-academic. Explores each strand and analyzes areas of agreement and disagreement to see if any reconciliations can be made across differences. Asserts that each strand is important in…

Criticizes an earlier essay that questioned the validity of contemporary educational research practices, especially those involving experimentation. Argues that research using experimentation is valid and can lead to new and generalizable knowledge. (FMW)

This paper describes the parallel treatments design, a nested single subject experimental design that combines two concurrently implemented multiple probe designs, allows control for effects of extraneous variables through counterbalancing, and replicates its effects across behaviors. Procedural guidelines for the design's use and issues related…

A series of remote viewing experiments were run with 12 participants who communicated through a computer conferencing network. The correct target sample was identified in 8 out of 33 cases. This represented more than double the pure chance expectation. Appendices present protocol, instructions, and results of the experiments. (Author/YP)

Discusses selective fidelity in training devices, when trainers must choose to simulate only the stimuli that are truly necessary to perform a task. Examples of selective fidelity are described from military tactical training devices; and the future of selective fidelity is considered, including behavioral and cognitive research contributions.…

Seven parents conducted assessments in an outpatient clinic using a prescribed hierarchy of antecedent and consequence treatment components for their children's problem behavior. Brief assessment of potential treatment components identified variables controlling children's appropriate behavior. Experimental control was achieved for six of the…

This commentary summarizes methodological and conceptual issues in functional analysis methodologies and offers some suggestions for their resolution. Considered are increasing complexity, absence of contingencies during assessment, use of subtle manipulations, alternative assessment strategies, analysis of antecedent influences on behavior,…

Used standardized mood-induction procedures to examine the relation between attachment security and representational-defensive processes. Subjects were 32 preschoolers ranked most secure and least secure using Attachment Q-Set. Found secure subjects were no more responsive to positive mood inductions, and no less responsive to negative ones, than…

Notes how preceding articles expand the repertoire of theory-relevant assessments of attachment, with a special emphasis on Ainsworth's concept of the secure base. Focuses on a number of issues raised by this collection that are particularly promising for theory development, including assessment of secure-base behavior and maternal sensitivity,…

Characterizes instructional practices that prevent discipline problems by encouraging learning and appropriate behavior from behavior analytic perspective. Notes that basic assumption of this perspective is that effective teaching strategies also serve managerial functions through development of stimulus control and management of behavioral…

Analog baselines are an experimental methodology for identifying the functions of maladaptive behavior of individuals with developmental disabilities in naturally occurring environments. This article identifies potential limitations of this methodology, including: fidelity of baseline design conditions, a narrow analysis of behavior, and limited…

This study examined how 3 students (ages 14-18, with emotional or behavioral disorders) allocated their responding across 2 concurrently available tasks associated with unequal rates and equal versus unequal qualities of reinforcement. It found that time allocated to concurrent response alternatives was approximately proportional to obtained…

This commentary on the use of gentle teaching with individuals with developmental disabilities examines the method's assumptions, describes its use of behavioral techniques, and criticizes its ineffectiveness. (JDD)

Extends control systems theory to analyze purposive collective behaviors, ranging from simple to complex, involving small and large groups. Suggests that complex collective phenomena can be explained as the repetition or combination of individual and collective sequences of action. Posits that control systems theory can be used to elucidate…
