TWO GROUPS OF SUBJECTS, DESIGNATED PACED AND UNPACED, WERE USED TO DETERMINE WHETHER SELF-PACING IS ADVANTAGEOUS OR NECESSARY IN THE DEVELOPMENT OF EFFICIENT TECHNIQUES OF MEMORIZING. EACH GROUP LEARNED 8 LISTS OF 25 WORDS EACH, 2 LISTS PER SESSION. AT THE FIFTH SESSION, THE PACED GROUP LEARNED TWO ADDITIONAL LISTS UNDER SELF-PACED CONDITIONS.…

This study tests the hypothesis that labeling facilitates recall in nursery school children if and only if it leads to rehearsal. Subjects were 34 children ranging in age from 47 to 53 months. During pretraining, those children in the Label group named pictures of animals and fruits as they were presented, while those in the No Label group matched…

Circumscribed interests are a fascinating and an understudied phenomenon in some individuals with autism spectrum disorders (ASD). Research in this area is likely to contribute to our understanding of ASDs and to advancing developmental knowledge on learning processes used to adapt to the demands of everyday social life. This study reports on a…

A description of four experiments confirming the theory that recall of a given item from a semantically categorized list is impaired by the presence of other items from this same category. This inhibitory effect of part-set "cuing" is interpreted here as a cue-overload effect. Selected references are included. (AMH)

The introduction of laboratory computers has facilitated investigation of quantitative theories in the investigation of memory. Data from a recent qualitative study was used to test two quantitative theories. The strength-resistance theory fitted the data quantitatively without significant deviations. Statistical tables and references are…

An attempt was made to identify comparable subjective subsequences in the serial learning of a prose passage and to examine the relationship of such organizational encodings to the variable of structural importance. Results of serial learning and free recall indicated learners associatively organized individual prose subunits into subjective…

This research project investigated some of the characteristics of primary and secondary memory. In the primary research, subjects were given a list of words followed by an interpolated task. The data of interest were the recall for terminal items in the list. Using this procedure, the researchers have demonstrated negative recency in initial…

The hypothesis that free recall curves reflecting effects of serial position, presentation time and delay of recall are attributable to subjects' pattern of rehearsal was explored. Experiments varied the patterns of rehearsal to examine the effects on recall. (CHK)

A description of a series of six experiments dealing with human memory processes. They examined the types of codes generated in maintenance rehearsal and the effects of rehearsal time at various single levels of encoding. Data confirmed earlier findings and led to conclusions regarding repetition, encoding and levels of processing. (AMH)

The relation between the amount of free study time needed to prepare for a perfect serial recitation and the number of words in the list was determined for individual subjects. List organization, controlled by experimenter or by subject, failed to affect difficulty. (CHK)

Two recognition memory experiments were used to study the retention of language and modality of input. A bilingual list of American Sign Language signs and English words was presented to two deaf and two hearing groups, one instructed to remember mode of input, and one hearing group. Findings are analyzed. (CHK)

This research on factors influencing verbal learning and retention has used new techniques, attacked new problems, and tested new theories while trying to keep the experiments systematic. Studies conducted involved (1) the effect of varying the length of the intertrial interval on the learning and retention of different types of learning tasks;…

Recall lists were presented to 40 black lower class and 40 white middle class children in this experiment. The purpose of the study was to examine a possible explanation of the relatively poor performance of black and lower class children on tasks requiring abstract learning abilities. It was reasoned that the threshold for the production of…
