A new model is proposed for explaining children's performance on Pascual-Leone's test of M-space. The new model is used to generate theoretical performance curves for children at four different age levels and seven different levels of stimulus complexity, and it is a viable alternative. Differences between the models are reviewed. (Author/RD)

In four experiments, evidence was found for a complex psychological representation of musical pitch. The perception of music depends not only on psychoacoustic properties of the tones, but also on processes that relate the tones to one another through contact with a well-defined and complex psychological representation of musical pitch.

Techniques that can be used to make the lecture method of teaching more effective include using pictures or objects to facilitate memory, using guided fantasies to stimulate students' imagination of processes, and the suggestopedia method for memorizing facts, principles, and vocabulary. (MSE)

Results of a choice reaction time study indicated that nine mildly retarded junior high students appeared to be less sensitive than nonretarded controls to stimulus probabiity information, particularly under degraded stimulus conditions. (Author)

A one-way analysis of variance was used to assess the effects of imposed (picture) and induced (play) imagery on the aural language comprehension of 80 kindergarten children who were randomly assigned to two treatment and two control conditions. No significant differences in recall were found. (Author/JD)

Pictorial contents of biology textbooks are examined as factors to be considered in assessing textbook readability. Includes data indicating that effect of color upon the observations and interpretations of photographs varies with the child's ability. Implications for textbook selection procedures are discussed.

Twelve male subjects were divided into three groups (model-plus-reinforcement (MR), model-only, and control) to determine if the presence of a verbalizing model to 35mm slides would elicit increased speech. Verbalization increased over treatments, especially in the MR group. Generalization to the word occurred in only three subjects. (Author/SJL)

Describes electroreceptivity in fishes, including information on electric signals in water, electroreceptors, electric organs, electric sense in weak-electric fishes, electrolocation, electrocommunication, and evolutionary considerations. (CS)

Three self-stimulating behaviors of a 6-year-old autistic boy were brought under S-delta stimulus control (a type of discriminative stimulus in the presence of which a given response is punished). (Author/DLS)

Subjects with eidetic imagery showed significantly more accurate recall of the stimulus pictures thereby supporting the importance of eidetic imagery as an early mnemonic system. (Author/DB)

Nearly twice the amount of variance in complexity scores accounted for by 17 antecedent variables was associated with Black rather than White subjects. The findings were truer of Black males. Independent variables were most strongly correlated with complexity scores for Black females. (Author)

Presents a rationale for studying the visual language of film. Reports on three studies that suggest some tentative answers concerning the manipulation of film and some promising approaches to the study of the medium. (RL)

Describes contributions of Neuro Linguistic Programming (NLP) to counseling practice. The Meta-Model, representational systems, anchoring, and reframing are described. Counselors interested in learning NLP can integrate many valuable new ways of communicating with clients and changing client behaviors. (Author)

Describes an investigation comparing visual and auditory clues effect on estimates of speakers' heights and weights, to determine if voice alone conveys as much information as visual clues. The results indicate that the differences between estimates based on photographs and those based on speech recordings are, on the average, very small.…

During self-recording and picture cue training, the Ss completed an increased proportion of independent task changes, and this behavior was maintained for more than ten weeks following removal of the training procedures. (Author/DLS)
