Deals with various myths about animals and plants. Discusses bats (not blind), toads (do not cause warts), dragonflies (will not sew up your mouth), horseshoe crabs (will not sting with their tails), owls (not so smart), and goldenrod (does not cause hayfever). (MH)

Attempts to emphasize some of the rather precise analytic and predictive values of evolutionary theory, applied to parental behavior. (Author/RK)

Four experiments tested the conditioned attention theory (CAT) of latent inhibition (LI). (Author/RK)

Proteins isolated from the brain and used as drugs can improve and apparently even transfer mental states and behavior. Much of the pioneering work and recent research with humans and animals is reviewed and crucial questions that are being posed about the psychologically active peptides are related. (BT)

Based upon British studies, suggests how the coexistence of different ant species can occur, and discusses competition and niche-separation in relation to a study made in Norfolk. Recommends the elucidation of the mechanisms of niche-separation in ants as an ideal student project. (JR)

Describes the use of capture-recapture techniques to estimate the population of taxis in Liverpool and demonstrates the points of similarity to animal population estimation. Considers advantages of studying taxis rather than organisms in introductory studies of the techniques. (AL)

Author presents data on Washoe, a chimpanzee taught American Sign Language; he concludes that this represents true language learning. (SP)

Describes procedures used to study abilities of chimpanzees to be taught written language. Words, sentences, questions, metalinguistics, class concepts, the copula, some quantifiers and if-then logical connections are investigated. Success seems attributable largely to non-linguistic cues. (JM)

The continuing erosion of financial support for undergraduate laboratories makes cost an increasingly important factor in the choice of undergraduate animal experiments. Projects employing insect predation by rodents, which require minimal equipment and pose a number of interesting questions about animal behavior, are described. (RM)

A conference on whether food and nutrients affect human behavior was held on November 9, 1982 at the Massachusetts Institute of Technology. Various research studies on this topic are reviewed, including the effects of food on brain biochemistry (particularly sleep) and effects of tryptophane as a pain reducer. (JN)

Tests were conducted to determine if domestic chicks would respond to multiple social separations with the cumulative disruption of social development seen in other species. (Author/SS)

The main finding of these four experiments was that the strong conditioning produced by a brief exposure to a truly random control weakened with prolonged exposure. (Author/RK)

Attempts to evaluate the hypothesis that rats are more hesitant to ingest novel-flavored substances while they are under the influence of a toxic agent than in the normal state. (Author/RK)

Assesses the present status of behaviorism by dividing this study into an evaluation of Behaviorism 1, based explicitly on Pavlov's conception of conditioned-response learning, and Behaviorism 11, single-handedly launched and almost completely dominanted by Professor B. F. Skinner. (Author/RK)
