The role of variation as a determinant of infant categorical responding was investigated in three studies of infants 7 to 7 1/2 months of age. Sixty-three infants, divided into groups of 21 each, were habituated to color slide poses of either one, two, or six different adult female faces. Their responses to a novel pose of a familiar face and a…

Three mentally retarded adult residents of a group home were trained to read survival words in four conditions (in the group home with one trainer; in the group home with two to three trainers; one trainer in the group home and the natural environment; and two to three trainers in the group home and the natural environment). Training was…

The present study examined Mexican-American and white subjects' response to same race stimulus persons who were differentiated only by the similarity of their beliefs to the subjects' beliefs. The prediction that a stimulus person whose beliefs are unknown and who is the same race as the subject would be responded to as if he had beliefs similar…

This paper develops a stimulus selection theory, based on an extensive review of previous research, which gives weight to context change or stimulus generalization decrement. The theory assumes no special compounding or configurational process, and accounts for the learning of successive discriminations without the addition of any special process.…

In this study, the effects of rewards on same-different judgments of size, color, and weight were investigated. Subjects were 45 children at the kindergarten and first-grade level. The children were assigned to one of three conditions: (1) rewarded for reporting black in the identification of the colors of balls contained inside gray jars, (2)…

This theoretical paper is concerned with the evaluation and preference responses of preschool children to light- and dark-skinned human figures. The paper examines the hypothesis that in children the frequently observed bias favoring light-skinned persons over dark-skinned persons is not a racial bias but is related to early learning experiences…

This study, which indicates that both age and variation in training affect children's concept formation, provides a basis for explaining the effect of age. Sixty-four 4- and 5-year-olds learned three novel concepts (animal-like, plant-like, and machine-like). Subjects were presented with either four different examples of each concept (multiple…

Contextualized instruction (also referenced as anchor instruction) is teaching a skill within a specific or functional context known as a target setting. The purpose of this approach is to teach transfer or generalization of a skill in order to increase the likelihood that what is taught in the training or classroom setting will be used in future…

The term, "schema," used largely as a descriptive convenience rather than a theoretical guidepost in social psychology is examined through an analysis of its development, function, and structure. This paper articulates a model of schema development in adults by defining a schema as a representation of some stimulus domain and a set of…

This study analyzes the generalization abilities of children with reading disabilities by comparing the performance of such children with that of a normal control group on a conditional discrimination learning-set task. Both groups, consisting of boys aged eight to ten, participated in the Wisconsin General Test Apparatus in a form modified for…

A dominant theme in cognitive psychology is that prior knowledge in long-term memory has a strong influence on an individual's cognitive processing. Citing numerous memory studies with children, knowledge base effects are presented as part of a broader picture of memory development. Using the sort/recall procedure (asking subjects to group sets of…
