This article presents the "Piirto Pyramid" framework for identification of talent potential. It explains how the pyramid identifies influences that are significant in the development of talents, including genetics, personality attributes, cognitive ability, talent, vocational, and environmental. Examples using Roy Rogers and Michelangelo are…

Discusses how the genetic aspects of schizophrenia must be described within the interactive context of psychosocial stress. Suggests that the mental health profession must consider the environmental and social components of this condition, including the clients' relationships, families, and communities. States that psychotherapeutic interventions…

Responds to J. McCroskey and M. Beatty's article in this issue. Argues that debates over relative importance of nature versus nurture are misguided because the relative influence of genetic and environmental components varies depending on specific genes and environments under consideration and their specific interactions. Explores what these…

Replies to C. M. Condit's response to the authors' article on communibiology in the same issue of this journal, arguing that some of her challenges to communibiology are seriously flawed. (SR)

Examines perspectives on family influences on child development. Maintains that genetic and biological factors and parental actions/attitudes make important contributions to individual differences. Draws on research on gender differences and conduct disorders to illustrate that parental influence on individual differences within cultures has been…

This article reviews youth violence literature and discusses relevant psychosocial risk factors, treatment approaches, prevention programs, and recommendations. Research indicates violent behavior is linked with multiple psychosocial factors and that the most effective treatment and prevention programs are those that address the multiple factors…

Learning to associate a conditioned (CS) and unconditioned stimulus (US) results in changes in the processing of CS information. Here, we address directly the question whether chemical appetitive conditioning of "Lymnaea" feeding behavior involves changes in the peripheral and/or central processing of the CS by using extracellular recording…

The ability to learn and retain novel information depends on a system of structures in the medial temporal lobe (MTL) including the hippocampus and the surrounding entorhinal, perirhinal, and parahippocampal cortices. Damage to these structures produces profound memory deficits; however, the unique contribution to memory of each of these…

A new generation of study programs worldwide is examining the links between brain science and children's learning problems and skills. One of its aims is to help bridge the gap between the laboratory and the classroom. Thus, by bringing multiple academic fields to bear in studying the brain, scientists hope to fashion cutting-edge research…

The consciousness of dizygotic twins in their communication of actions and events as seen in the visual cliff pictures published by E. J. Gibson and R. D. Walk (1960) was studied in Sweden. In the process of communication, many different state spaces are generated. The methodology demonstrates that ecological and biophysical properties of language…

This paper addresses research implications of proposed modifications of the definition of "severe emotional disturbance" to include students with conduct disorders. Research questions focus on understanding the nature of antisocial, aggressive behavior in children and youth and identifying what services they need. Research is cited suggesting that…

Staggering statistics and dramatic headlines about the destruction of rain forests, the world's richest ecosystems, are only a small part of the devastating story of global deforestation. This volume provides comprehensive coverage of this complex scientific and political catastrophe-in-the-making and examines the costs and the consequences, in…

The concept of autonomous identity, derived from Piaget's theory of personality, is distinguished from other applications of the term "autonomy" in psychological theory. Introductory comments suggest that both biological and mental development express autonomy in the same two senses: as self-regulating and progressively self-liberating.…

Despite considerable work concerning relationships between cognition and language in the second year of life, these relationships remain obscure. Clarification depends on resolution in at least three major areas. First, studies should be expanded beyond the scope of cognitive prerequisite models that have been difficult to conceptualize and that…

A multifactorial model is presented that depicts a representative set of dimensions involved in child abuse and neglect. The model includes parental, ecological, and child factors linked to precipitating situations and/or events that result in child abuse or neglect. An excerpt from the records of an abused child illustrates the model. Also…
