In order to determine if infants possessed contingency awareness and if it were related to a temporal unit, two hypotheses were constructed. (1) Reinforcement of a response would probably lead to emission of that response only if the infant's next response occurred within a period of time during which he could remember the preceding…

Mentally retarded subjects who could read were tested on their ability to pronounce words and to produce meaningful associates. Analyses of their responses indicated an overuse of a strategy of memorizing words as a way to recognize words in print and an inability to consider word meanings in terms of abstract referents. A comparison of these…

This study investigated whether recall of expository information by a learner will be affected by the mode or combination of modes through which the information is presented. Subjects, 359 fifth-grade students, were randomly stratified into four treatment groups on the basis of sex and reading ability. Treatment for each of the groups was as…

This study investigated five ability tests related to the water-jug problem. Previous analyses identified two processes used during solution: means-ends analysis and memory of visited states. Subjects were 240 undergraduate psychology students. A real-time computer system presented the problem and recorded responses. Ability tests were paper and…

To develop a coherent description of the knowledge and processes involved in skillful word recognition, a study was devised in which 16 adults participated in four related experiments. The purpose of the first experiment was to examine some basic aspects of the processing of words, pseudowords, and nonwords and to discover basic differences in…

Three conjunctive concept-learning problems were presented to 70 educable mentally retarded (EMR) children (9 to 14 years old) and 76 controls (7 to 10 years old) to assess the effects of four verbalization conditions and the presence or absence of a memory aid on concept attainment. Verbalization conditions were the following. (1) no…

Cued-recall and two-alternative, forced-choice recognition measures were used to evaluate subjects' retention of the specific wordings of studied texts. Results obtained after 10-minute and 24 hour retention intervals suggest that the studied wordings of texts are functional components of their memory representations. Theories that assume…

A framework for viewing human text comprehension, memory, and recall is presented that assumes patterns of abstract conceptual relations are used to guide processing. These patterns consist of clusters of knowledge that encode prototypical co-occurrences of situations and events in narrative texts. The patterns are assumed to be a part of a…

Developmental selective learning processes of elementary school age children were investigated using two types of incidental learning methodologies. The purposes of this study were to: (1) compare the effects of the two types of incidental learning paradigms, and (2) determine the influence of different kinds of stimulus relationships on…

The purpose of these studies was to test a theory of associative context (defined as the association between two words in a pair) on recognition memory. The theory states that culturally associated words in a pair and nonassociated words in a pair differ after a single study trial in terms of their frequency representation in memory. Two…

In an earlier study, subjects who were shown the two words "inside" and "consult" at two different points in a study list of two syllable words were willing to accept the word "insult" as having been on the study list. It was concluded that each syllable had a representation in memory over and beyond the semantic factors which are normally…

The purpose of this study was to provide a more complete understanding of the storage and retrieval processes of developmentally different youngsters. Forty-four second and fourth grade subjects were given a lesson consisting of 25 facts to learn and remember. Half of the group learned the facts in a context containing superordinate statements…

Volume 2, the appendix to the final report of Project FAST, consists of prose selections used to study the effects of text reduction techniques on the comprehension and recall of written materials among visually handicapped and hearing impaired subjects. Each selection is presented in various versions such as 10 percent subjective deleted, 20…

This paper reports three experiments concerning methodological issues in studies on incidental learning performance which use verbal and nonverbal procedures and which appear to be hampered by differences in stimulus materials, learning opportunities, and dependent measures. The first study, using 128 children from grades 3, 5, 7, and 9, attempted…

The purpose of this paper is to gain insight into the nature of the reading process through an understanding of the general nature of sensory processing mechanisms which reorganize and restructure input signals for central recognition, and an understanding of how the grammar of the language functions in defining the set of possible sentences in…
