Subjects were given three trials to speak and to write as fast as they could both the alphabet and a set of two-digit numbers. The speed or oral responding was approximately 6 syllables per second for letters and 7 syllables per second for digits. The speed for writing was approximately 2 items per second for both digits and letters. Correlations…

Four experiments were conducted to examine the effects of various processing instructions on the rate of false recognition. The continuous single-item procedure was used, and false recognitions of four types were examined: synonyms, antonyms, nonsemantic associates, and homonyms. The instructions encouraged subjects to think of associates, usages…

This paper describes three studies designed to determine whether there are age-related differences in children's memory for implicit and explicit information in prose. In the first study, six experimental paragraphs were read individually to a total of 60 children in grades K-5. Each child was then asked four verbatim recall questions (specific…

Evaluated with two age groups (mean age 8.1 years or 10.6 years) totaling 22 learning disabled children was whether there is an age related increase in recognition for visual nonverbal short term memory (STM) and the effects on STM of stimulus dimensionality, primacy, recency, and second choice responses. A serial recognition task was used to…

The report describes a number of experiments designed to compare the acquisition of a compensatory tracking skill in adaptively controlled and open loop conditions. It covers one dimensional tracking and two dimensional tracking. Several one dimensional tasks were employed in order to control the degree of subskill interference and memory load.…

The purpose of this study was to determine: (1) the effects of repeating words in compound sentences; and (2) the differences in encoding processes in short term memory for natural language materials compared with nonlinguistic material. A series of give experiments was administered to first graders, college students, and older subjects. The…

The relationship between visual recognition memory and performance on a paired-associate task for good and poor readers was investigated. Subjects were three groups of 21, 21, and 22 children each, with mean IQ's of 98.2, 108.1, and 118.0, respectively. Three experimental tasks, individually administered to each subject, measured visual…

The present study explores accuracy and speed of responses by the five-year-old child to expanded and conjoined sentences. The following factors were considered: (a) number of transformations, (b) types of transformations, (c) auxiliary-type sentence expansion and (d) type of query (those designed to elicit responses which should reflect…

Experiments in the Psychology Department of George Washington University suggest the possibility of constructing sub-languages of English which can accelerate communication. "Quickspeak," a restricted redundancy language, eliminates from natural language those linguistic cues which are reconstructable from those that remain. Principles…

The purpose of this research project was to evaluate the effects of prompts and cues in paired-associate learning. Experiment One was to investigate the effects of cues and prompting on the learning of Japanese vocabulary. Experiment Two duplicated the above using digit-nonsense syllable combinations as the paired associates. The next three…

A comparison was made of short- and long-term visual and auditory memory in relation to visual and auditory interference. The questions investigated were: (1) will interference be greater when it occurs in the same modality (auditory or visual) in which it was learned (i.e., similarity hypothesis), or (2) will interference be greater when it…

The experiments described in this report attempt to further understanding of the storage and retrieval of factual information. In the first five experiments, organization of simple prose materials is varied. Effects upon both accuracy and order of recall are discussed in terms of retrieval strategies determined by organization. The fourth and…

The viability of visual imagery as a prose-learning process was evaluated in two experiments with elementary school children in this study. In experiment one, two concrete ten-sentence passages were constructed. The attributes of two subclasses were contrasted in each passage (two kinds of monkeys in one passage, and two kinds of cars in the…

Previous research has found that spoken rehearsal is superior to silent rehearsal during verbal discrimination learning. The frequency theory posits that verbal discrimination (VD) learning improves as the frequency differential between the correct and incorrect member of each pair increases. Erlebacher, Hill, and Wallace (1967) tested this…

In an attempt to ascertain the facilitating functions of audiovisual between-channel redundancy in information processing, a series of audiovisual experiments alternating auditory and visual as the dominant and redundant channels were conducted. As predicted, results generally supported the between-channel redundancy when input (stimulus) was…
