Retroactive interference (RI) in prose learning was investigated in an experiment where passages were constructed on the basis of a predetermined logical structure. This structure made it possible to operationally define similarity and assess the effects of RI for inferential information as well as that stated directly in the original passage.…

Three measures of verbal input organization (category clustering, associative clustering, and subjective organization) were employed to compare the performances of 30 normal and 30 educable mentally retarded (EMR) elementary school males of equal chronological age on various free recall learning tasks. Subjects were given 12 successive trials on…

A study is reported in which pairs of synonyms, antonyms, coordinates, and super super-subordinates were presented dichotically to university students. After each pair the subject reported what he heard. In one condition the two members of a pair were presented simultaneously, and in another they were presented sequentially. (Author/RM)

Evaluates the findings and measurement techniques about the incidence and role of internal speech in the information processing abilities of preschool and primary-grade children. (RL)

Supports previous findings that preschool children evidence significant amounts of subvocal speech, and that a significant relationship between recall and subvocal speech exists for boys but not for girls. (RL)

Describes two experiments in which Ss were given 48 trials, using word lists as stimuli, followed by an unexpected final free recall test. (Author/RM)

Subjects learned one, two, or three verbal lists simultaneously. Recall of the common list after 24 hours increased directly as the number of lists learned simultaneously increased. Assuming that simultaneous learning reduced interference, the interference was from extraexperimental sources of a proactive nature. (Author/CP)

Investigates the additive memory effect of two modes of presenting information to elementary children on the retention of both images and words. Children represented more information in pictorial than in verbal form. The visual-verbal treatment group scored higher on most of both verbal and pictorial responses than the visual treatment group.…

A cross-sectional study that investigated memory variables in 100 subjects in 4 age ranges (17-22, 40-50, 60-70, and 75-99) found that the 60-70 year olds were more impaired with respect to retrieval than storage and the major problem with memory among the 75-99 year olds was retrieval from short- or long-term memory. Because the study was…

Results indicated that discovery subjects took significantly longer than verbal reception subjects in the first-, third-, and sixth-grades to reach the original learning criterion. Verbal reception subjects generally demonstrated performance which was superior to discovery subjects on all measures of retention and transfer. (Author/BJG)

In two separate paired-associate learning experiments each employing 40 university students as subjects, the contribution of individual differences (IDs) in arousal to short- and long-term retention was investigated using IDs in salivary response to lemon juice stimulation as an index of arousal. Experimental subjects were pre-selected out of 184…

The experimental program in structured activities in perceptual training was said to have two main objectives: to train children in retention of visual and auditory images and to increase the children's motivation to learn. Eight boys and girls participated in the program for two hours daily for a 10-week period. The age range was 7.0 to 12.10…

The purpose of this article is to examine the capacity limitations of the active memory system as seen in the nature of the forgetting mechanisms. (Author/NCR)
