Two groups of 10 adult aphasics received auditory-verbal "yes-no" questions, including egocentric, environmental, pictorial, and relationship items, either in a consistent order or random order. Support was found for the existence of a hierarchy of difficulty among the types of questions, but there was no significant difference between…

Children and adults were more likely to claim a word was presented as a picture than vice versa. Results indicated the absence of developmental differences in reality monitoring and similarity in representational processes of children and adults. (BC)

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…

To investigate decision level processes involved in bilingual word recognition tasks, Dutch-English participants had to name Dutch-English homographs in English. In a stimulus list containing items from both languages, interlingual homographs yielded longer naming latencies, more Dutch responses, and more other errors in both response languages if…

The study investigated the role of social reinforcement, when teaching two preschoolers with no functional vocal verbal behavior first instances of echoic responses, using rapid motor imitation responding. The dependent variables for the experiment were: (1) echoic tacts (echoics presented under the controlling variables of tacts) and (2)…

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)
