Spontaneous and model-induced production of a valuational style of inquiry was studied in 128 third-grade children. (Authors)

Study conducted to investigate attention span in relation to various schedules or regimes of reinforcement. (Author/MB)

Analyses indicated that varying the range of test stimuli changes the discriminability of the stimuli within that range, even though the physical differences among these stimuli remain constant. (Author)

Among the findings were that the treatment procedure produced immediate and substantial suppression effects on the self-injurious behavior, which generalized to the nontraining environment and endured over an eight-month interval. (Author/DLS)

Infants were tested for recognition and discrimination of expressions. Ten-month olds familiar with a mix of happy and surprised expressions demonstrated generalized discrimination of positive affect. Only after seven months does dependence on the presence of expression-specific features for affect recognition and discrimination diminish. (BC)

In earlier studies with rats, the effectiveness of the auditory element of a tone--light discriminative stimulus was enhanced when the conditioned incentive value of the compound was negative rather than positive. The present experiment systematically replicated these results in pigeons trained to press a treadle in the presence of a tone--light…

An evaluation of selective generalization of habituation on the basis of meaningful categories of stimuli. Also explored are the sex differences in conceptual generalization of habituation. Subjects were 36 toddlers with a mean age of 40 months. (SDH)

This paper describes the nature of stimulus and response generalization and identifies a number of tasks related to generalization that are commonly taught in early childhood programs. Substantial research has demonstrated that stimulus generalization does not occur automatically and it can often be achieved only as a result of special programing.…

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)…
