This research examined the impact of formative quizzes on e-learning designed to teach volunteers how to tutor struggling readers. Three research questions were addressed: (1) Do embedded quizzes facilitate learning of e-content? (2) Does the announcement of upcoming quizzes affect learning? (3) Does prior knowledge interact with quizzing and…

In order to address criticisms raised against the cognitive mediation hypothesis, three experiments were conducted to develop a more direct test of the hypothesis. Taken together, the three experiments provide converging support for the cognitive mediation hypothesis, reconfirming the central role of cognition in the persuasion process.…

Historically, accounts of object representation and perceived similarity have focused on intrinsic features. Although more recent accounts have explored how objects, scenes, and situations containing common relational structures come to be perceived as similar, less is known about how the perceived similarity of parts or objects embedded within…

It is proposed that many phenomena of human hypothesis testing can be understood in terms of a general positive test strategy. With this strategy, there is a tendency to test cases that are expected to have the property of interest rather than those expected to lack that property. (Author/LMO)

The hypothesis testing model is the most dominant model of adult concept learning. Based on task performance, subjects in the experiment were categorized into three levels of concept attainment. Results suggested the hypothesis testing model adequately reflected the performance of only the most successful subjects. (Author/DWH)

The speech products of 104 young adult Melbourne males were analyzed in order to determine whether the linguistic dimensions of the speech product bear a necessary relationship to the cognitive dimensions. (Editor)

This paper suggests that although there is reasonable evidence to support that portion of the Collins-Quillian theory of semantic memory which hypothesizes that words are ordered hierarchically in memory, there is little evidence in support of their hypothesis of cognitive economy of storage in memory.

The primary goal of this study was to determine the degree of support for cognitive balance formulations of inference processes in hypothetical social situations using a procedure that controls for certain other systematic biases that may affect inferences." (Author)

In this research subjects are asked to justify three common erroneous solutions and the correct solution, all of which purport to be the "correct solution". It was predicted that the subjects would give reasons supporting any given solution, and indicate a high degree of confidence in the correctness of their justifications. (Author/RK)

We tested whether the distinctiveness effect in memory (superior memory for isolated or unusual items) only occurs with conscious recollection or could emerge with recapitulation of the type of processing that occurred at study even in the absence of recollection at test. Participants studied lists of categorically isolated exemplars. In…

R. F. Wang and E. S. Spelke's (2000) finding that disorientation disrupts knowledge is consistent with egocentric but not allocentric coding of object location. The present experiments tested the hypothesis that egocentric coding may dominate early on but that once an allocentric representation is established, then target location is retrieved…

Piagetian tasks have more to do with the child's ability to inhibit interference than they do with the ability to grasp their underlying logic. Here we used a chronometric paradigm with 11-year-olds, who succeed in Piaget's conservation-of-weight task, to test the role of cognitive inhibition in a priming version of this classical task. The…

The authors present a comprehensive consideration of the process characteristics of visual search in contexts that vary in their meaningfulness. The authors frame hypotheses regarding process architecture, stopping rule, capacity, and channel independence, using analytic results and a rigorously specified dynamic system to characterize a set of…

Neurological and behavioral findings indicate that atypical auditory processing characterizes autism. The present study tested the hypothesis that auditory processing is less domain-specific in autism than in typical development. Participants with autism and controls completed a pitch sequence discrimination task in which same/different judgments…
