This study tested whether conditioning to one member of a compound stimulus can be blocked by presence of a second member to which the response was previously conditioned. Eight mentally retarded students (ages 7-9) were presented with words, sometimes accompanied by pictures. Six students performed best when words were presented without pictures.…

Verbal and musical stimuli were presented to infants in a study of the relations of evoked potential left-right amplitude asymmetries to gender and hand preference. There was a relation between asymmetry and hand preference, and for girls, between asymmetry and stimulus condition. Results suggest a gender difference in cerebral hemisphere…

This study compared three methods of stimulus preference assessment for four verbal children (ages six to nine) with attention deficit hyperactivity disorder, specifically evaluating the utility of a verbal choice procedure for assessing relative reinforcer value. Verbal and pictorial stimulus-choice assessments identified high- and low-preference…

Feedback is one of the most important aspects of improving performance because it corrects, reinforces, and motivates. It can also create bonds and enable students to see that their performance is important. This article defines feedback, presents three important functions of feedback, identifies the four forms of feedback, gives examples of…

Ernst Mach is most closely associated with a positivism that demanded a language of close contact with reality. Mach linked this view with the tradition of the quest for an ideal language in which meaning is a property of a word. Logical positivism and the S-R psychology of the early B. F. Skinner also participated in this ideal-language…

The experience tutoring a student who is blind in four semesters of university calculus is discussed. The mechanics, instructional strategies employed, and the challenges encountered are examined as they relate to teaching mathematics. It was found there are important similarities and also differences as compared to sighted students in teaching…

The present study employs event related potentials (ERPs) to verify the utility of using electrophysiological measures to study developmental questions within the field of language comprehension. Established ERP components (N400 and P600) that reflect semantic and syntactic processing were examined. Fifteen adults and 14 children (ages 8-13)…

In three studies, the effects of visual and phonological distinctness on the visual-verbal paired associate learning of dyslexic and normal readers at the age of 10-12 were examined. We hypothesized that both groups would be equally affected by the visual distinctness of the pictures, whereas the learning performance of the dyslexic children would…

The purpose of the present experiment was to study storage properties of dual codes for pictures and words by manipulating instructions and to study retrieval properties by manipulating the representational form of the test items. (Author)

This study was designed to determine whether children 3, 4, and 5 years of age could demonstrate their metaphorical competence equally well in words and in pictures. Previous studies which have investigated young children's metaphorical ability have often encouraged young children to make judgments of similarity which rely almost exclusively on…

Results of a series of studies suggested that excessive early vocal stimulation may be detrimental to infants' cognitive processing, and that optimal development may be associated with a moderate amount of early stimulation. Study 1 involved 59 3-month-old infants and their mothers. Study 2 observed 23 mothers and infants seen 3 months after the…

Semantic theory, its relationship to comprehension, the nature and function of semantic memory, and results of some research on semantic memory and bilinguals are discussed through a review of recent literature. The findings discussed seem to confirm these general observations regarding semantic memory and bilinguals: (1) there is integration and…

Previous studies of the effect of age and modality on digit span task performance have yielded inconsistent results. To eliminate some of the methodological difficulties in prior research, 18 college students and 18 older adults were given the digit span task by means of three different modalities: (1) visual successive; (2) visual simultaneous;…

The role of imagery is assessed in verbal concept identification and evidence is found that some concepts can be coded as images. (Author/AM)

Investigates extent to which perceptual factors of speed and flexibility of closure represent more general processes also operating in cognitive and personality domains by including in a single factor analysis perceptual tests and new tests requiring cognitive abilities resembling closure abilities operating in the perceptual domain.
