in the present dichotic memory research, the addition of either a monaural stimulus suffix on the unattended ear or a binaural suffix was shown to selectively impair unattended-ear performance. (Editor)

The ability of 4th, 6th, and 8th graders to use structures inherent in a list of permuted symbols, defined in terms of Piagetian theory, was investigated. Age differences were noted. Results supported the theoretical notion that environmental event structure facilitates learning. (ST)

The present article attempts to discover if learners can use three higher order transitions between subunits- to extend structures made of right-branching trees, to elaborate a tree by adding substructures, alternating responses from the two subsystems. (Author)

Findings were: it did not matter whether the seriation involved the hues used in subsequent tasks or other hues; the presence or absence of reinforcement during perceptual pretraining did not affect pretraining, training, or transposition behavior; and seriation pretraining produced increased transposition in the intermediate-hue problem.…

Two groups of reading-disabled (RD) children were compared with controls (age- and IQ-matched competent readers), on a serial running memory task. RD children performed reliably worse than their controls due to an inability to encode serial items in the form of serial phonological patterns. (Author/RD)

Some research on the stimulant effect of caffeine suggests that the amount of behavioral enhancement produced by caffeine may depend on subjects' prior experience with the task and the drug. A study was undertaken to test whether prior experience with a task while under the influence of caffeine would facilitate performance of that task. Male…

The development and application of a learning procedure for the seriation structure of children in the oscilatory state are described. The procedure was based on the structural genetic theory of learning. A study consisting of design and verification stages was carried out in Cali, Colombia. In the design stage six seriation treatments involving…

A comparison of oral interviewing and written proctoring procedures is described. Students were required to present units orally or in writing from unit study guides. Final exam scores were positively correlated with the number of oral interviews one student interviewer gave to another student, and negatively correlated with the number of…

Three strategies frequently employed in individualized instruction were tested in a three-way repeated measures design that involved eight computer exercises over a period of 6 weeks. Exercises compared individual with paired study, pretests with no pretests, and serial with parallel mastery. Posttests revealed an advantage for individual study…

The multivariate effect of task sequence, memory support, and state anxiety was investigated using a nonverbal concept acquisition task. Ninety-five Indian college students were randomly assigned to four treatment conditions resulting from the task sequences of 1) easy-to-hard and 2) hard-to-easy and from memory support versus nonmemory support.…

Children's short-term memory was studied under two experimental conditions: one in which recall was expected to be facilitated because of the provision of a study period, and one in which a distracting task was imposed that was expected to interfere with recall. Forty subjects at each of two age levels, 7 and 11 years, were tested in a…

The purpose of this study was to examine the use of auditory memory tests to predict reading achievement of elementary pupils. Auditory memory was defined as the ability of an individual to reproduce digits, letters, sounds, words, or serial commands, immediately and correctly, in sequential order, after having heard them only once. One hundred…

To study the effects of planned seriation experiences on the acquisition and retention of seriation abilities of four-year-old children, fifty children from four preschool centers were assigned to control and experimental groups and tested before and after exposure to the experiences. Data analysis indicated that the experimental group had higher…
