This study aims to apply a sequential analysis to explore the effect of learning motivation on online reading behavioral patterns. The study's participants consisted of 160 graduate students who were classified into three group types: low reading duration with low motivation, low reading duration with high motivation, and high reading duration…

Two years after participating in a replication of the Stallings Effective Use of Time (EUOT) Program, ten teachers were re-observed and interviewed to determine the extent to which they had maintained the measured changes in their behavior patterns. Subjects were selected for the follow-up from a 27 EUOT teacher sample based on having exhibited…

The research on situation with developing "green skills" in conditions of transition to "green economy" is analysed in this article. Kazakhstan like many other states has been going through transition to "green economy" since 2013. Economic reforms have made an impact on the system of environmental education. The…

Prevalence of self-injurious behavior (SIB) is as high as 50% among children with autism spectrum disorder (ASD). Identification of risk factors for the development of SIB is critical to early intervention and prevention. However, there is little empirical research utilizing a prospective design to identify early risk factors for SIB. The purpose…

Single-case designs (SCDs) are a class of research methods for evaluating intervention effects by taking repeated measurements of an outcome over time on a single case, both before and after the deliberate introduction of a treatment. SCDs are used heavily in fields such as special education, school psychology, social work, and applied behavior…

This dissertation investigates how distributional information in the speech stream can assist infants in the initial stages of acquisition of their native language phonology. An exploratory statistical analysis derives this information from the adult speech data in the corpus of conversations between adults and young children in Russian. Because…

In a nonrandomized or observational study, propensity scores may be used to balance observed covariates and trajectory groups may be used to control baseline or pretreatment measures of outcome. The trajectory groups also aid in characterizing classes of subjects for whom no good matches are available and to define substantively interesting groups…

Behavioral observation has become increasingly important in research in developmental and clinical psychology, as well as in program evaluation and instructional research. Several statistical approaches to assessing the dependability of behavioral observation were reviewed. The demand for accurate and efficient paradigms for behavioral observation…

This commentary focuses on the application of D. Rogosa and G. Ghandour's work to observational research on classroom processes. Rogosa and Ghandour have shown that the short length of an observation is typically the dominant source of error. Investigators should conduct observations for as long as possible. (SLD)

The monograph by D. Rogosa and G. Ghandour represents a body of cohesive and comprehensive research that can be the basis of a new measurement theory combining features of generalizability theory and strong true-score theory. Principles, approaches, arguments, and conclusions are reviewed; and critical comments are offered. (SLD)

Issues raised with the statistical models developed are discussed point by point, restating the emphasis on finite observation time, and reiterating the criticism of traditional psychometric methods. It is noted that the language and technical formulation of psychometrics can be extremely awkward in dealing with biased estimates. (SLD)

The present study investigated differences between referred and nonreferred children and their families on the basis of home and clinic observations and parent questionnaires. Subjects were 28 families with children between 4 and 8 years of age who had been referred to a clinic for acting-out behavior and 28 nonreferred controls matched on several…

Describes exercises designed to give students experience in using methods of naturalistic observation to quantify behavior. Students construct a coding system of the behaviors observed in a small mouse colony, gather data by instantaneous and focal animal sampling, and use the data to calculate interrater reliability and sequence analysis. (GEA)

Papers and discussants' comments from a symposium on issues concerning infants' reactions to strangers are presented. Researchers agreed that there is a developmental shift in infant behavior at 7 to 9 months of age when the infant becomes more cautious in approaching strangers. However, investigators hypothesize that the presence of the mother,…

This speech presents the use of experimental designs and research procedures to help counselors develop effective treatment methods for clients. Baseline and treatment phases are delineated as the two basic phases occuring in most "N=1" designs. These designs are divided into the categories of single and multiple time series designs. The…
