The fates of phrenology and evolutionary theory in the 19th Century are studied in order to assess the current status of sociobiology and predict its future. (Author/AM)

Seven rhesus monkeys reared on diets high in phenylalanine to induce phenylketonuria (PKU--a metabolic disorder associated with mental retardation if untreated) were compared with normal, pair-fed, and younger controls; frontal brain-lesioned monkeys; and those raised on high-tryptophan diets in three object discrimination tasks.

Evidence is found against a learning or instrumental model of aggression production, and a novel theory is advanced suggesting that infants are genetically predisposed to acquire specific behavioral characteristics shown by the mother. (Author/JMB)

Examined the development of pattern recognition in infant pigtailed macaques using the familiarization novelty technique. Results indicate that by at least 200 days postconception subjects show a consistently reliable visual response to novelty. (Author/RH)

Discusses the optics of fly fishing, considering where to cast the fly once a fish is seen. Also considers what the fisherman looks like to the fish, examining refraction at a water surface, actual and apparent light rays, and how sticks in the water might look to a fish. (JN)

Three groups of macaque mother/infant dyads were observed while each lived in ecological settings that differed in level of foraging demand and, hence, the amount of work each mother was required to perform to obtain her daily rations. Findings suggest that in monkeys, as in humans, when mothers are psychologically unavailable to their infants,…

Argues that common anatomical and functional characteristics exist among the brains of reptiles, mammals, and man--the most significant commonality for educators being social behavior. Illustrates inherited behavior, including behavior observed in classroom and believed to be learned by placing it in context of a model "triune"…

Social and nonsocial behaviors of infant rhesus (macaca mulatta) and pigtail (M. nemestrina) monkeys reared in total social isolation were compared with those of socialized controls. Results question the generality of rhesus total isolate behavior as a model for some human problems. (Author/SB)

Purpose of study was to investigate the applicability of Piaget's theory and methods to the study of conservation in nonhumans. Two out of four subject monkeys achieved stringent and statistically significant performance criteria in sameness-difference judgment tests and showed significant generalization in the fewest possible trials. (Author/SB)

Findings are consistent with behavior observed in rhesus monkeys reared under similar conditions, thereby broadening the base from which to extrapolate to human development. (Authors)

Describes an animal laboratory course using male Siamese fighting fish which is inexpensive, compact, and permits students to conduct a wide variety of behavioral investigations. (Author/CK)

Attempts to define "creative categorization" using animal behavior and human perception as examples. (RK)
