This study investigated the effects of parental models plus nondifferential praise and expansions plus nondifferential praise on 2-year-old children's spontaneous use of color and size adjective-noun combinations. Mothers modeled either a color or size adjective-noun combination and expanded the other. Both parental models and expansions increased the children's spontaneous use of the target adjective-noun combinations, but expansions produced a stronger effect than models. These results, and naturalistic data indicating that parents often provide a large number of expansions for their children, suggest that expansions may play an important role in normal language development. 相似文献

The hexagon of J. L. Holland (1973, Making Vocational Choices: A Theory of Careers, Englewood Cliffs, NJ, Prentice-Hall) is a useful heuristic device for predicting congruency and consistency among the six personality/environment types specified by his theory. One limitation of the traditional hexagon is the implicit bidirectionality: the hexagon displays a single distance between two types. People in applied areas may assume a symmetry which does not exist. Examples are given of situations in which a consistent asymmetry occurs; e.g., in the illustrative data presented, C (Conventional) types are more likely to have E (Enterprising) as a secondary interest than E types are to have C as a secondary interest. Implications of such asymmetries are discussed and suggestions made concerning counseling and other applications. 相似文献

Attention to visual and nonvisual imagery, elicited by an imagery questionnaire, was studied using both within and between subjects analyses of cardiac and respiratory parameters. Visual imagery was accompanied by more regular interbeat heart rate (HR) and shorter, more stable respiratory cycles than nonvisual imagery. “Visually-oriented” thinkers (visualizers), identified by a word association test, manifested less overall variability in HR than “verbally-oriented” thinkers (verbalizers), as well as less variable HR and respiratory period during visual imagery. Visual and nonvisual imagery differed in HR variability for verbalizers and in respiration period for visualizers. The results are discussed in terms of the concepts of attention deployment, “mental load”, cerebral asymmetry, and stylistic personality differences in cognitive functioning. 相似文献

The present study examines the transfer of imitative learning to other nonimitative performance conditions and compares imitative and nonimitative performance under contingencies of differential reinforcement for S0 behavior, differential reinforcement for nonimitative behavior, and extinction. Many authors have suggested that a child's continued imitative performance of rewarded SD and unrewarded SΔ behavior is a function of subtle social cues or experimental demand present in most generalized imitation procedures. The two experiments presented here support that conclusion but also provide evidence that conclusions drawn from such generalized imitation studies were generally accurate. Even though a child's trial-by-trial imitative performance appeared to be a function of procedural artifacts, the child's later performance in the role of a model indicated that a functionally interdependent generalized response class of imitative behavior had been learned while the child imitated. As such, these experiments generally supported Baer's secondary reinforcement hypothesis for imitative performance and suggest that future research employ nonimitative tasks such as reversed imitation as a measure of imitative learning. 相似文献
