Discussed theories relating forgetting rates and age. Developed a theory and mathematical model for examining storage failure versus retrieval failure, true forgetting versus test-induced processes, and storage- versus retrieval-based reminiscence. A series of experiments studied these factors in children and seniors. (BC)

A study of the effectiveness of self-instructional booklets and computer software for teaching dental students endodontic diagnosis found that the self-teaching method may be as effective as traditional lectures in teaching concepts central to development of clinical decision-making skills. Sampling difficulties created problems in assessment of…

Three experiments with preschoolers tested the independence of the current state buffer from working memory. Findings indicated that when a teddy bear was an object put away with other toys, only half the preschoolers remembered its location despite explicit instructions. When the teddy was a character interacting with children, all remembered its…

Two experiments examined memory of 7-month-olds after 2-week retention interval for passages of two Mozart movements heard daily for 2 weeks. Results suggested that the infants retained familiarized music in long-term memory and that their listening preferences were affected by the extent to which familiar passages were removed from the musical…

The author investigated voice context effects in recognition memory for words spoken by multiple talkers by comparing performance when studied words were repeated with same, different, or new voices at test. Hits and false alarms increased when words were tested with studied voices compared with unstudied voices. Discrimination increased only when…

In this article we suggest a method of evaluating learner expertise based on assessment of the content of working memory and the extent to which cognitive load has been reduced by knowledge retrieved from long-term memory. The method was tested in an experiment with an elementary algebra tutor using a yoked control design. In the learner-adapted…

Recent evidence indicates that certain forms of memory, upon recall, may return to a labile state requiring the synthesis of new proteins in order to preserve or reconsolidate the original memory trace. While the initial consolidation of "instrumental memories" has been shown to require de novo protein synthesis in the nucleus accumbens, it is not…

Deletions, translocations, or point mutations in the CREB-binding protein (CBP) gene have been associated with Rubinstein-Taybi Syndrome; a human developmental disorder characterized by retarded growth and reduced mental function. To examine the role of CBP in memory, transgenic mice were generated in which the CaMKII[alpha] promoter drives…

Information storage in the brain is a temporally graded process involving different memory phases as well as different structures in the mammalian brain. Cortical plasticity seems to be essential to store stable long-term memories, although little information is available at the moment regarding molecular and cellular events supporting memory…

This research examined the effects of differences in the emotions associated with an event on participants' reports of the experience. Forty-eight 10-year-old participants in a soccer tournament reported their final competition shortly after the game and 5 weeks later. Although all children reported the same event, members of winning vs. losing…

The purpose of this investigation was to quantitatively and qualitatively identify the study methods and learning strategies that veterinary students used to study anatomy during their first year of professional school and to correlate these with their academic achievement and long-term recall of information. It was surmised that active study…

This paper discusses a mental model of learning based on the processes of attention, perception, processing, and application. The learning process starts with attention, such as curiosity, excitement, expectation, or fear; in pedagogy this is called motivation. New impressions are dependent on and interpreted against the background of previous…

This study sought to determine a useful frequency for refreshing students' memories of complex procedures that involved a formal computer language. Students were required to execute the Microsoft Disc Operating System (MS-DOS) commands for "copy,""backup," and "restore." A total of 126 college students enrolled in six…

Three experiments were conducted, all employing undergraduates in college courses taught according to personalized system of instruction (PSI) principles. Experiment I examined retention as a function of the feedback delay interval in an introductory anthropology course using short-answer essay tests. Experiment II varied the feedback delay…

A study of the agenda-setting influence of the mass media on adult viewers explored (in a series of five experiments) how political knowledge stored in long term memory can be activated by the media, leading to decisions about issue salience. Spreading activation theory formed the basis for the study, and priming--the concept that the activation…
