The goal of the study is to analyze the morphological processing of real and novel verb forms by heritage speakers of Russian in order to determine whether it differs from that of native (L1) speakers and second language (L2) learners; if so, how it is different; and which factors may guide the acquisition process. The experiment involved three…

Constructing well-formed sentences is an important element of writing. However, many students struggle with this skill; in particular, writers with learning disability (LD). In this study sentence-combining practice with a peer-assistance component was used to improve the ability of four young students with LD to construct sentences and compose…

This investigation built upon previous studies that compared effectiveness and efficiency among instructional methods. Instructional effectiveness and efficiency were compared among three conditions: an incremental rehearsal, a more challenging ratio of known to unknown interspersal word procedure, and a traditional drill and practice flashcard…

The aim of this paper is to explore the conditions under which generalisation from single case studies, in the sense of making inferences concerning a wider class of phenomena beyond a case, is reasonable. Two sets of conditions, in particular, provide the basis for our consideration of this issue. The first is an exploration of the impressive…

Describes the establishment of a psychological space for any set of stimuli by determining metric distances between the stimuli with the probability that a response learned for a stimulus will generalize to the other. (Author/TW)

Correlation is one of the most widely used analytic procedures in the behavioral sciences. The bivariate correlation is implicit in all classical analyses ranging from t-tests to canonical correlation analysis. The most common correlation coefficient used in statistics is the Pearson product-moment coefficient of correlation, which is represented…

Two pilot efforts were undertaken to teach moderately and severely handicapped children music. In the first, moderately and severely handicapped children were found capable of making gains in rhythm, melody, and keyboard after 3 months of weekly half hour group music instruction sessions and three weekly half hour practice sessions. Ss did not…

Compares a successful job classification procedure used to make use of validity generalization findings in new settings with a much simpler holistic judgement approach for accomplishing the same purpose. Results showed that the latter approach was just as effective, but was much less time consuming and costly. (LLL)

The article reviews social skills interventions that have been attempted with mentally retarded persons beginning with the less complex skills and moving to multifaceted ones. Summary tables are presented which list the skill(s) taught, the instructional methods used, the effectiveness of the intervention and the generalization effects for 22…

Conducted a reliability generalization study for the State-Trait Anxiety Inventory (C. Spielberger, 1983) by reviewing and classifying 816 research articles. Average reliability coefficients were acceptable for both internal consistency and test-retest reliability, but variation was present among the estimates. Other differences are discussed.…

R. N. Shepard (1987) has proposed a universal exponential law of stimulus generalization, yet experimental data are often Gaussian in form. Theories have been proposed to reconcile the discrepancy, but as proposed here, a simple discrete diffusion process may underlie both types of gradient. (SLD)

In three experiments, infants enacted event sequences and one week later reenacted the sequences while using props that had replaced some of the props used in the first sequences or after selecting props functionally equivalent to the props used in the first sequences. These results demonstrated infants' spontaneous generalization and their…
