Arguments about the existence of language-specific neural systems and specifically about the independence of syntactic and semantic processing have focused on the event-related brain measures (ERPs) as tool to monitoring moment-by-moment the cognitive processes underlaid. In the present experiments, the available evidence indicates that the ERP…

A follow-up account of a mother's attempts to provide her blind daughter, now aged six, with knowledge of the physical world through the manipulation of three-dimensional objects and two-dimensional tactile representations. The case is made for the value of pictures to the development of children's understanding in general; and for the child who…

Two methods are used to test the hypothesis that natural categories have reference point stimuli in relation to which other stimuli of that same category are judged. (Author/DEP)

Three experiments are reported in which 15 babies were presented with visual stimuli which varied in shape and distance from the eye. Results indicated that the majority of subjects binocularly fixated all three stimuli and it was concluded that the newborn baby has the basic requirements for binocular vision. (Author/GO)

This study was designed to determine whether the effectiveness of stimulus intensity declines with age. The results indicated that infants 10 weeks and younger responded on the basis of size, while infants between 10 and 24 weeks looked more at a bull's-eye than at a striped pattern regardless of size.

Article focused on R. L. Gregory's theory of distortion illustions and his defense of that theory. (RK)

Twenty-four learning disabled children (ages 8 to 12) were given tests of memory and selective attention in order to highlight the similarities and differences between the two. Ss were found to be sensitive to interfering stimuli especially when the task tapped areas of their weakness. Users of effective cognitive strategies in one type of task…

A discussion of why the prime concern of the video programer should be the arrangement of the subject matter for visual rather than aural communication whenever possible. (Author)

The report describes the characteristics and usage of a computer program, the Relatedness Coefficient Matrix Program (RCMAT), designed to summarize associative responses given to verbal stimuli by individual respondents and by groups of respondents. The computer program uses the response distributions for individuals, and the pooled response…

A linear relationship was found between judgements given by 160 subjects to 7 objects presented as single stimuli (alpha judgements) and judgements given to the same objects presented with a condition (gamma judgements). This relationship holds for alpha judgements and the gamma judgements that belong to a family of constant stimulus and varying…

From the best-fit lines corresponding to sets of families of conditional judgements, the constant stimulus family and the constant condition family, both defined for a same scale object, the coordinate values of the point of intersection of both lines (indifference point) are obtained. These values are studied in relation to the mean values of the…

Internal verbal processes were assumed to play a central role in complex school learning tasks. The research reported was concerned with a certain class of internal verbal behavior. The implicit associative response (IAR) was conceptualized as an internal verbal response that may occur when an individual sees or hears a word. Results of four…

Given that the associative meaning of a word is defined as the set of associates evoked by that word and the relatedness between two words is dependent upon the degree of overlap of their respective associative meaning, this program computes the relatedness coefficient for two values of the weighting component.

Two-day-old chicks were found to prefer an ancestral maternal call over a brief repetitive pure tone burst when stationary models emitted the calls; however, other chicks prefered the repetitive tone over the maternal call when the models emitting the calls were moving. (JMB)
