Various examples of communication in species ranging from bumble bees to dolphins are examined in this paper. Focus is directed to indications of the cognitive ability of each species. The signals of cognition include evidence of: adaptability to a new situation; long term memory; and the property of displacement. Most of the sources reviewed…

A three-phase investigation of memory and metacognitive development was conducted to learn how teachers structure children's study activities to develop memory and metacognitive skills. In the first study, observations of 69 teachers of kindergarten through sixth grade classes showed a peak in strategy suggestions at the second and third grades.…

The foundations of knowledge by tradition have been treated analytically, and knowledge has been characterized as a theoretical subject. This article introduces a steering mechanism as the prerequisite for a study of knowledge work and maintenance on empirical grounds. Knowledge is treated synthetically, that is, as something that exists only…

The hypothesis that variation in accessibility of categorical knowledge affects its use as an organizational device was tested in this experiment using 36 second graders and 36 fifth graders from a middle-class community within San Diego, California. The students memorized each of two lists of words that differed in category representativeness.…

Responding to recent advances in developmental and cognitive science research on knowledge acquisition, this report presents a theoretical framework for analyzing cognitive development as a process of learning. The first section summarizes three developmental characteristics recognized in both the Piagetian and the quantita experimental tradition:…

This paper discusses questions pertinent to a definition of cognitive structure as the knowledge one possesses and the manner in which it is arranged, and considers how to select or devise methods of describing cognitive structure. The main purpose in describing cognitive structure is to see whether differences in memory (or cognitive structure)…

As part of a larger study of developmental deficits in the skills of automaticity of name retrieval, phonological awareness, and memory span and their role in reading disabilities, a study tested 13 average and 14 poor fourth-grade readers for digit and letter naming speed, phonological awareness, and digit span. Among the reading skills assessed…

A study compared the way in which subjects belonging to four different age groups produced written recall and summary responses after being presented with a narrative story. A seventh-grade-level, 500-word story that contained 78 idea units was presented to two groups of adolescents (mean ages, 14.14 years and 17.55 years) and two groups of adults…

Twenty-four children (aged 7-16 years) with seizure disorders (SD) were compared to 30 children with diabetes mellitus (DB) and 30 children with no chronic illness. Using a variety of assessment devices, the children were compared on intelligence, academic achievement, attention, memory, perceived competence, and parents' perceptions of child and…

A 1973 study by Lott posed some serious questions about attitudes toward children, the quality of childhood experiences with parents, and the extent of agreement with the women's liberation movement. A replication and extension of Lott's research was conducted to assess the current attitudes of 76 college students and 63 community residents toward…

A study investigated processing differences between metaphorical and literal versions of the same sentences. The purposes of the study were (1) to directly compare the on-line processing demands of metaphoric and nonmetaphoric sentences, and (2) to examine the consequences of such sentences for memory performance. The subjects were 39 college…

Two experiments were conducted to determine whether the connective structure of a passage might protect interrelated information from interference by irrevelant information in sentence recognition. Subjects of both experiments were college students enrolled in introductory psychology classes. In each, a rating task for unconnected phrases was…

In order to study children's strategies for solving geometric matrices similar to those in the Raven's Progressive Matrices, ninety 7-, 10-, and 13-year-old boys and girls were administered tests of auditory and visual memory, the Raven's, and geometric matrices. The matrices varied in number of elements (1 to 3) and number of transformations (0…

Memory for sex of the speaker and language of presentation of a spoken message was high and reliably better when the features were instrumental for comprehending the message than when they were not. This suggests that the physical characteristics of an event may be deeply or elaborately encoded when they are meaningful in light of the task…

Explanations for memory development have tended to focus on acquistion of general strategies and metaknowledge. Recently, emphasis has been given to the knowledge base as a whole, including general world-knowledge and domain-specific knowledge and procedures. Evidence is presented from the memory development literature showing why strategies and…
