Two experiments are described. One measured performance of subjects on pairs of concurrent verbal tasks, monitoring sentences for certain items while reading. Secondary task performance combined with a primary task is proportional to its performance in isolation. The second experiment checked certain results of the first. (CHK)

Describes ways for developing visual imagery in the early childhood education program, preparing children for discrimination learning and reading instruction. (RL)

Four profoundly retarded multiply handicapped children (with a mean age of 12 years) were placed in a situation where auditory stimulation was made contingent on a visually directed lever-pulling response. (Author/MH)

Recognition scores of 12 moderately and mildly retarded children (mean ages 13 and 14 years) for positive and negative discriminative stimuli were tested after a single trial through a discrimination problem list. (Author/CL)

Discusses three experiments designed to examine the problem of the internal representation of meaning of a verbal stimulus. (Text is in Italian.) (CFM)

This study attempted to develop a hierarchical scheme appropriate for theoretical science concepts and to empirically validate the scheme with a sample of sixth grade students. (Author/GO)

The purpose of the study is to compare pictorial esthetic preferences for typical Navaho children with those given by children of three other cultural groups to determine if, in fact, Navaho children's preferences do display a distinctive patterning. (Author/AM)

Results of an administration of the Matching Familiar Figures Test to 1484 Guatemalan children indicated that response time correlated more highly with the difficulty level of items within a test than with accuracy. (MS)

Using a modified Posner "encoding function" methodology, group differences in semantic encoding speed were assessed under conditions in which subjects encoded pictures of common objects to determine physical identity matches, name identity matches, and superordinate identity matches. Results of primary interest revealed group differences in basic…

Fifteen stutterers (aged 5-16) were treated using graded airflow, tension/relaxation, and electromyographic biofeedback to reduce stuttering frequency. In a second study, addition of a discriminative stimulus control procedure to maintain fluency made the treatment program more effective than the first study and achieved a level of <1% stuttered…

The slower progress of semantic memory research is attributed to the difficulties involved in testing the relevant theories. This paper proposes a model for testing such theories using the Continuous Response (CR) task. The model establishes a link between the rate of recall and the semantic relationships among the category items. (JAZ)

Investigates to what extent discrimination learning through time delay of multistimulus, distinctive-feature prompts is a function of the inclusion and configuration of the S-prompt. Results of two experiments with children aged four and five indicate that most subjects did not learn the task assigned unless two distinctive-feature prompts were…

Two approaches of statistical testing are critically reviewed. A new approach, which is a hybrid of the two, is proposed. The new approach requires the researcher to think about the two types of potential inferential errors and an explicit alternative hypothesis of interest. (VM)

Two experiments examine the sorts of cues that might be available to facilitate children's ability to discriminate between memories for their own actions. Results suggest that the differences in discrimination performance demonstrate the importance of kinesthetic cues and visible consequences for children's memory discrimination. (Author/RWB)
