This study was designed to investigate whether problem solving inefficiency in preschool children is the result of subprocess deficiencies in the children's use of logical rules and to assess the influence of 2 mnemonic components (encoding and rehearsal) on problem solving ability. The study subjects, 108 preschool children, were presented with…

Jones (1976) has shown that the memory trace resulting from the viewing of a picture corresponds to a "fragment" of that picture. This research shows that the fragmentation hypothesis also correctly represents the recall of memories derived from sentences, i.e., the functional unit of memory, the mnemonic trace, is a fragment of the original item.…

These experiments consider similarities and differences between classifications of pictorial and verbal stimuli in order to investigate whether the kinds of information used differ depending on the stimulus class. Three hypotheses regarding the information used in picture and word classification were evaluated. (Author/RK)

This research attempts to determine whether integration of information occurs when the information is presented partly in the verbal modality and partly in the pictorial modality; in other words, does cross-modality integration occur? (Author/RK)

Males and females from grades 3, 6 and college viewed sets of five or seven letters in a 4x4 matrix and remembered either names of the letters, positions of the letters within the matrix or both letters and positions. At all grade levels females remembered letters better than positions, males did equally well on both. (MS)

A stages-of-learning model was used to examine effects of picture-word manipulation on storage and retrieval differences between disabled and nondisabled grade 2 and 6 children. Results showed that disabled students are poorer at memory tasks and in developing the ability to reliably retrieve information than nondisabled children. (Author/RH)

Six experiments investigated loss of availability of surface form in sentence comprehension. Explanations for the loss included: (1) linguistic hypothesis; (2) memory limitations hypothesis; (3) integration hypothesis; and (4) processing shift hypothesis. (LMO)

In a study of second graders, results supported the hypothesis that recognition memory would be disrupted when children's attention control strategy required the same cognitive operations as the task material to be studied. (Author/MP)

In two experiments, children ages six through eight, 10-year-old children, and college students were shown several series of slides. Each series told a unique "story" and was followed by oral questions. Results illustrated the increasing interdependence of the verbal and visual systems with age. (Author/MP)

The first experiment determined that verbal interference (shadowing) was detrimental to the subjects' memory of words and high similarity pictures; the second, designed to minimize the possibility that students would sort through the pictures, indicated that verbal interference did not decrease memory of high similarity pictures. (Author/JEG)

Comparisons between recall levels following simple acoustic or visual tasks and the simultaneous visual-plus-acoustic task are not based upon equivalent amounts of interference within each modality. This research attempts to test more precisely the relationship between visual and acoustic interference by using a sequential rather than a…

A total of 12 second- and fifth-graders' semantic decision times for pictures and words were analyzed relative to the predictions derived from unitary- and dual-memory models. (MS)

The guessing-bias and proactive interference hypotheses of the Ranschburg Effect were investigated by giving three groups different instructions as to guessing during recall. Results failed to support the prediction that the effect should be reduced or eliminated on shift trials. Neither hypothesis received significant support. (CHK)

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)

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)
