Differential observing responses (DORs) are additional response requirements used to promote orientation to a stimulus in a discrimination task. Farber and Dickson (2023) recently provided a DOR taxonomy, and these authors reported that no prior research has compared the effects of distinct DOR requirements. We compared the effects of two DOR…

Second and sixth grade children solved a series of four-and eight-dimensional discrimination learning problems dictating selection of hypotheses which could be monitored by means of blank trials. Differential effects of stimulus complexity upon the performance of the two age groups are discussed. (GO)

A specially designed discrimination learning task was used to investigate whether the performance of kindergarten and first grade children could be improved through explicit training with a simple hypothesis-testing strategy. (Author/MP)

Cognitive organization in problem solving was investigated using a transfer paradigm. (SB)

This study is designed to test the hypothesis that an inability to separate incoming information into discrete messages is a source of young children's relatively poor performance in selective attention tasks. Subjects were 27 children drawn from kindergarten, second grade and fifth grade classes. (Author/GO)

Presents two experiments which examined: (1) the tendency to make differential cue-producing responses to the values of dimensions that vary within or between settings; and (2) the hypothesis that children have more experience with problems following a two-choice simultaneous discrimination format than a successive one. Subjects were third- and…

In this study, hypothesis probe techniques were used to provide trial-to-trial monitoring of second and third grade children's use of feedback. (SB)

Tests the hypothesis that strong approval motivation is developmentally lower than weaker approval motivation, since the high-approval-motivated individual is more dependent on the external world than on internal cues and norms. (Author/ED)

To clarify the roles of IQ and mental age (MA) in hypotheses behavior, MA-matched subjects at three levels of IQ and three levels of MA received blank trial discrimination learning problems using procedures designed to discourage position-oriented responding. (Author/BD)

Subjects were trained against their initial dimensional preference in a two-dimensional simultaneous discrimination learning task. (RH)

According to Hypothesis (H) theory, learning should be very difficult when the number of Hs the subject samples from is very large and/or the correct H is not available. These assumptions were tested with third- and fourth-grade children. In general, results supported these assumptions. (Author/MP)

Three studies of elementary school children's problem-solving procedures in intentional discrimination tasks are reported. Subjects were children selected from kindergarten and grades 2, 3, and 6. (Author/MP)

A study involving 110 fifth- and sixth-graders (51 male and 59 female), classified as low or high in effort orientation, assessed the effects of task- versus performance-oriented instructions on a computer-assisted test programed to ensure that all examinees failed to solve all problems. Problem-solving strategy analyses were preformed. (TJH)
