The objective of the current report is to review experimental findings on centrally patterned movements and sensory and descending modulation of central pattern generators (CPGs) in a variety of animal and human models. Special emphasis is directed toward speech production muscle systems, including the chest wall and orofacial complex during…

This paper brings some data to bear on the criticisms, claims, and arguments that Skinner (a) denied or dismissed biological participation in behavior, (b) addressed it only late in his career or more often later than earlier, or (c) addressed it only because of the overwhelming evidence for it or the criticisms that he had overlooked it. For…

Does the name of the special interest group, "The Experimental Analysis of Human Behavior," imply that those who analyze the behavior of human animals must organize themselves apart from those who analyze the behavior of nonhuman animals? Is the use of nonhumans in experiments really not relevant to the analysis of the behavior of humans? If so,…

Describes studies at winter bird feeders which enhance instruction of ecology at the University of Michigan biological station. Background material is provided for field activities in which black-capped chickadees are observed and for home range determination and population estimate activities. (DH)

Discusses current learning theories, indicating that though many psychologists and ethologists now agree on using a mechanistic approach, some linguists doubt its adequacy. Implications of research on the mollusk "Aplasia" to understand the learning process are included. (JN)

For the past half-century, a racetrack outside San Diego has recruited educators for jobs during the summer break. But earning extra cash is not the only reason these seasonal employees return every year. Del Mar in San Diego, which was opened in 1937 after being bankrolled, in part by Bing Crosby, remains among the best-attended tracks in the…

What are the specific and essential things that ought to be taught? On which precise base is a given progression proposed and, more specifically, are articulated the levels determined by teachers? This questioning fundamentally goes beyond the classical thoughts about the relationship between social practice and school practice. An authentic…

Research suggests that intuitive parental didactics related to infants' production of vocal sounds, vocal imitation, and vocal play are a prerequisite of human language acquisition. Microanalyses of videorecords of parent-infant interactions have revealed intuitive forms of parental behaviors that parents carry out unknowingly and can hardly…

Demonstrates how high or low levels of adult structuring of activities during free play activities can induce sex-typed social behavior by preschool children. Examines the effects of naturally occurring variations in children's play on sex-typed social behaviors. (SA)

Discusses three themes important for the future progress of developmental psychology: (1) a focus on not only individuals, but also individuals in networks of relationships; (2) description as the first, but not the only, stage in the analysis of developmental processes; and (3) a multidisciplinary approach. (BC)

One aspect of ethological methodology, behavioral categorization, is applied to the study of young children's social behavior in preschool classrooms. Studies are reviewed and recommendations for future use of ethological methods, with specific reference to categorizing children's play, are offered. (LB)

Describes two studies involving chimpanzee mother-infant pairs in Tanzania between 1980 and 1987 that implemented control theory concepts. The first identified behavioral development in infant chimps; the second observed the growth of independence and parenting patterns. Concludes that the hierarchy of controlled variables develops consecutively…

A quantitative ethogram was developed for the zebra finch, using one-zero focal animal sampling on an ethologically comprehensive checklist of 52 behavioral items, and it was assessed for interobserver reliability and construct validity. Applying the quantitative methods of psychometrics allows verification of ethological theory and testing of…

Reintroduces the ethological concept of social dominance, and interprets it from a strategy-based perspective. Maintains that, by adopting this approach to social dominance and explicitly incorporating developmental processes and uniquely human capacities, human social-dominance patterns appear to be more similar to primate patterns than commonly…

Infant temperament is theorized to have a strong genetic basis. Yet, studies of the stability of temperament and molecular genetics research on temperament have revealed inconsistent findings. One reason may be because research has not taken into account the influence of early social experiences. We review research on aspects of infant…
