Several experiments tested the occurrence of the "Kamin effect", i.e., the deficit in performance of an incompletely learned avoidance task, in terms of discrimination (choice) behavior by rats. (Editor/RK)

Repeated, isolated presentations of a stimulus typically reduce the subsequent ability of that cue to become an effective conditioned stimulus. This phenomenon is known as the latent inhibition effect. Four experiments investigate this effect. (Editor/RK)

Authors see the provision of an "aesthetic atmosphere" as one of their greatest challenges. One is an art specialist and the other is a principal. Outlines some of the ways in which they have successfully met that challenge. (Editor/RK)

The roles played by veterinary science departments are creditable and important, says this head of a department of veterinary science. Those roles will reflect an absolute increase in participation with veterinary schools on a regional and national basis, and a relative increase in direct involvement in veterinary education. (LBH)

Compared tendencies of adults and rhesus monkeys to escape adaptively when uncertain. In a visual discrimination task using a threshold paradigm, humans and monkeys escaped trials in which they were uncertain of the stimulus. In a similar task with constant stimuli, some humans escaped adaptively, but one escaped infrequently and non-optimally,…

Presents evidence that although patients with semantic deficits can sometimes show good performance on tests or object decisions, this pattern applies when nonsee-objects do not respect the regularities of the domain. Patients with semantic dementia viewed line drawings of a real and chimeric animals side-by-side and were asked to decide which was…

Drawing on the notion of the domain-specificity of recognition, reviews evidence on the effect of language in classification of and reasoning about categories from different domains. Looks at anthropological infant classification, and preschool categorization literature. Suggests the causal nature and indicative power of animal categories seem to…

Describes 10 predator/prey relationships that occur on the coast. Predators are compared to criminals and prey to their victims along with details of crime scenes. Accurately describes the habits and habitats of the criminals and presents games and activities that feature the relationships between predators and their prey. (Author/SOE)

Describes an activity on worms that investigates their anatomy and habitat and reactions to various environments. (Contains 12 references.) (YDS)

Infants were familiarized with plastic animals from one of two categories (land or sea) that were judged similar or variable by adults. Infants were then tested with novel animals from the same or a different category. Thirteen-month-olds in the similar familiarization condition dishabituated to novel animals of a different category and, to a…

Describes the results of a survey using an open-form questionnaire to determine student attitudes toward animal experimentation. Results indicate that children's views about animal experimentation for research depend on the purpose of the research. More than half felt experimentation for pure research is inappropriate. (DDR)

States that tracking, or the study of changes in landscapes, offers clues that give us a direct experiential connection to the past and consequently enriches our appreciation of how the present came to be. Discusses tracking animals and footprints, tree tracking, and geomorphology or landforms. (AIM)

Describes action research experiences as the study was conducted and reflection upon the results. Determines whether 1st grade students have similar misconceptions about animals. Investigates whether a constructivist approach focusing on students' prior knowledge could alter the misconceptions. (Author/KHR)

Major differences between plants and animals are presented. Discussed are autotrophs and heterotrophs, plant growth and development, gas exchange, the evolution of plants, ecosystem components, the alleged inferiority of plants, and fungi. (CW)
