Preoperational and concrete operational kindergarten children received stimulus differentiation training, either with or without feedback, and then a series of discrimination learning problems in which a blank trial probe was used to detect a child's hypothesis after each feedback trial. Piagetian stage theory requires elaboration to account…

Three experiments examine the information extraction process in adults and elementary school children reading paragraphs or words. In experiments 1 and 2 subjects were presented paragraphs to read and to search for specified targets. In experiment 3 subjects were asked to judge whether briefly presented pairs of letters were the same or different.…

The ability of first and third graders to evaluate their recall performance was assessed. Subjects' accuracy in assessing their recall after the fact was contrasted with indications that children are poor predictors of their recall performance. (GO)

Accuracy of imitation by 60 kindergarten subjects was examined using a task in which a female modeled a series of pegboard patterns and delivered accuracy contingent feedback. Four methods of feedback and a no-feedback control were compared. (GO)

Experiment 1 examined the effect of negative attention and repeated demands on the noncompliant behavior of children. Experiment 2 studied the relative effectiveness of negative attention, isolation, ignoring, and a combination of procedures in reducing noncompliance in children. (GO)

An apparatus is described which permits one experimenter to obtain high quality audio and video tape recordings of young children's behavior in cognitive-linguistic tasks while leaving the experimenter free to concentrate on working with the child. (GO)

A developmental reversal in accuracy was obtained for third and sixth graders and adults who judged class membership of patterns presented in a same-different task. Reversal accuracy appeared to result from an increase with age in orientation-free judgments. This hypothesis was confirmed in the subsequent two experiments. (GO)

Four experiments were designed to determine if a visual stimulus class could be established under certain conditions for retarded adolescents, and if subjects trained to select some members of the set in response to an auditory stimulus would select all members of the set in response to that auditory stimulus. (GO)

Racial attitudes of 5- and 8-year-old children were measured before and after the children were administered a negative reinforcement procedure which changed their evaluations of color concepts. Earlier findings with preschool children were replicated, and a larger change in racial attitude scores was obtained. (GO)

The relationship between discriminability of scaling stimuli and assessed dimensional dominance was investigated in three studies. Results indicated that kindergarten children bring to the experimental situation a dimensional preference even when the values of all dimensions present are of equal and known discriminability. (GO)

Students in grades 4, 6, and 8 were required to indicate whether or not a stimulus word belonged in either of two semantic categories that were held in memory. Results indicated that even for the youngest children semantically similar categories required less search time than dissimilar categories. (GO)

This study relates excitatory and inhibitory personality variables of a heterogeneous group of severely retarded children to performance on a discrete trial, successive go-no-go intradimensional discrimination learning problem, which was followed by stimulus generalization tests on a color hue continuum and extinction trials. (GO)

This study examines the phonetic effect and retention of preschoolers who were presented with a differential picture-matching task of phonetically similar and unrelated lists, under a condition in which verbal components of the task were emphasized and under a condition in which the children engaged in overt, cumulative rehearsal. (GO)

Children in grades 1 and 4 and adults were given instruction to image or to verbalize a sentence in order to study a stimulus provided aurally. Both types of instruction enhanced memory, but results indicate the greater requirements for subject-generated mediation to some degree penalized younger subjects and benefited older ones. (GO)

Elementary school students and adults were presented with a paired comparison task of visual complexity in which contour and presence or absence of structure in the patterns were manipulated. Results indicated that complexity judgments of all subjects were affected by the presence of structure at lower levels of contour. (GO)
