A review of data on parent-offspring resemblances in intelligence is presented in the context of correlation, regression and variance predictions from the polygenic model and an environmental model. (Editor)

The present research was designed to investigate the relationship between binary units of information and the subjective use made of them. (Author)

This paper had three aims: 1, to make more widely known two methods of assessing recognition, one based on ranking and the other on rating, 2, to describe three experiments comparing the two methods, and 3, to give a preliminary account of the results of some theoretical calculations. (Author/RK)

A model of the response process based on signal-detection theory (Tanner & Swets, 1954) was used to analyse PI effects in three different tests of short-term memory. (Editor)

Article attempted to ascertain whether bilateral language representation occurred at the expense of certain musical as well as of spatial abilities. (Author/RK)

It was the purpose of this study to find out the role of cognitive contents in determining the level and form of the manifestations of curiosity in children. (Author)

The present paper reports some experiments designed to determine the role of selectivity in identifying speech sounds, rather than in selecting which of two streams of partially analysed speech sounds will receive further processing. (Author)

Children between 4 and 10 years participated in a study of their ability to discriminate pictorially represented depth. Stimuli comprised pictures in which depth cues were systematically manipulated.

The present study predicted that, if arousal is unitary, then stressors which separately induce it should be additive in their effects on behavioral efficiency. (Editor)

Article investigated two new, parallel, multiple-choice group tests of reasoning, suitable for literate subjects from 10 years to adulthood. (Author/RK)

This study explored tactile retention by children with attention-demanding and modality-specific distractors. (Author)

The present study reports two investigations; the first concerning the relationship between WISC verbal-performance IQ discrepancy and reading and spelling retardation, the second representing an analysis of the spelling errors made by these children. (Author)

The present study evaluates the relationship between social learning and developmental theories in the prediction of changes in cognitive behavior. (Author)

A computer model (program MK 10) which was described in a previous paper (Wolff, 1975 "a") was intended to show how the segmental structure of a language may be learned by young children despite the apparent absence of consistent physical markers like pause or stress for the boundaries of words and other linguistic segments. (Author)

Investigates the properties affecting the time taken to read individual words and to discriminate between words and non-words. (Editor/RK)
