This study examined the relative influence of observation, feedback in training seriation, and imitative motor activity in facilitating conceptual development. (CM)

A study involving four caregivers evaluated the effectiveness of a systematic instructional procedure known as constant time delay (CTD) in teaching caregivers how to use CTD to teach their adolescent or adult children, siblings, or clients with disabilities, response chain skills. Results found the procedure to be effective. (CR)

Many studies have analysed how goal directed movements are corrected in response to changes in the properties of the target. However, only simple movements to single targets have been used in those studies, so little is known about movement corrections under more complex situations. Evidence from studies that ask for movements to several targets…

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)

Several different issues in the temporal coding of words were subjected to experimental analysis. Two experiments evaluated three response measures (recency judgments, position judgments, lag judgments) used to index temporal coding. Lag judgments were found to be of little use; subjects could make valid position and recency judgments without…

The objectives of this study centered on ability of first-grade students in seriate learning, the strategies used, the effects of the seriation variable on task performance, and the effects of the number of objects used. Students from four randomly selected schools were asked to order a set of 4, 6, 8, or 10 objects on length or weight. The…

After tachistoscopic exposure of a row of letters, recall functions show bowing and skewedness similar to the standard serial position curve that results from sequential presentation of elements. A similar curve is generated by recall of binary elements presented briefly and simultaneously. Prior investigators have interpreted this effect as an…

Three topics in factor analysis are covered: a) a reliability coefficient for assessing the quality of a maximum likelihood factor analysis, b) an application of three-mode factor analysis to serial learning data, showing variations in learning curves over stages of learning and individuals, and c) the use of personal probability functions to…

Effects of lower versus middle class parental occupation, verbal intelligence, and action content of pictured stimuli upon nonverbal serial recall were investigated in white first-graders attending a semi-rural elementary school in southeastern Michigan. Forty lower class and 20 middle class children, (half boys and half girls) were grouped on the…

Two experiments investigated serial recall with eight-word lists in which the frequency rating of the terminal word was manipulated. The effect on recall of two kinds of verbal "stimulus suffix" as well as a control noise suffix was also tested. Recall for the terminal items in the lists was analyzed. (Editor)

This experiment examined the spoken serial recall by adults and second grade children of aurally presented lists of digits, synthetic stop consonants, and synthetic vowels. (SB)

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)

Results of this experiment provide support for the findings by Piaget & Inhelder (1973) that children's memory drawings of a seriated display improve over time as their cognitive abilities develop. (Author)

Four experiments investigated the attentional requirements of learning as assessed by a serial reaction time task. The effects of a dual-task condition, plus the responses of memory disorder patients, were also investigated. The relationship between learning and awareness, preserved learning in amnesia, and the separateness of memory systems are…

The von Restorff effect was clearly demonstrated in intentional learning and in Type 2 incidental learning, extrinsic case, of children. (Author)
