Bronfenbrenner's (1979) ecological model proposes that events in higher order social ecosystems should influence human development through their impact on events in lower order social ecosystems. This proposition was tested with respect to ecological violence and the development of children's aggression via analyses of 3 waves of data (1 wave…

Results indicate that there is no simple relationship between type of observer present and children's aggressive responding following exposure to an aggressive model. (Authors)

With no expectancy to perform, vicarious reward had no effect on spontaneous imitation. (Authors)

The theory of social comparison postulates that the tendency to compare one's performance to others' will decrease as a function of the discrepancy between the quality of one's own performance and that of the comparison person. (Author/MB)

Experiment studied the effectiveness of social reinforcement by a model who demonstrated varying degrees of commitment to the norm of giving or social responsibility. (Authors)

Live behavioral and televised behavioral models were the most effective, and live verbal models were the least effective. The effects of the deviant models were more stable over time than the effects of the conforming models. (Authors)

An investigation of immediate and delayed vicarious reinforcements upon children's imitative self-sacrificing behavior. (Author/MB)

Suggests ways to use dynamic systems analysis to illuminate the pluralistic and multidimensional model described by Larivee, Normandeau, and Parent (2000). Issues discussed include the characteristics of developmental transitions, such as hysteresis; nature of growth processes, such as hierarchical development or predator-prey interactions; and…

A developmental model for paranoid behavior has been proposed which postulates that the attempt to adapt to sustained aversive maternal control by manipulative social approach behaviors (open adaptive style) leaves the person vulnerable to emerging paranoid tendencies. (Author)

Performance demonstrated that the conceptual style and cognitive tempo of the model changed the styles and tempos of the Ss and that these effects generalized to independent tasks. (Author)

Discusses building blocks for a developmental psychopathology, focusing on studies of risk, competence, and protective factors. Describes studies of stress and competence, giving particular attention to methodology and strategies for data analysis. A three-model approach to stress resistance is also presented, and Project Competence is evaluated…

Results lend support to the notion that children at different ages are differentially responsive to various conceptual-strategy models. (Author)

The question-asking behavior of disadvantaged Mexican-American second-grade children was found readily modifiable using an adult model offering contingent praise. (Authors)

Relevance of cognitive and developmental variables to observational learning and imitation is also discussed. (Authors/MB)
