Subjects completed a baseline stimulus matching procedure designed to produce two symmetrical stimulus relations; A1-B1 and A2-B2. Using A1, B1, and two novel stimuli, subjects were then trained to produce a common key-press response for two stimuli and a second key-press response for two further stimuli across two blocks of response training.…

Although the role of working memory in sentence comprehension has received substantial attention, the nature of this relationship remains unclear. The purpose of this study was to examine the interaction between general, nonverbal working memory (WM) and sentence parsing (SP) in normal English-speaking adults. Accuracy and reaction times were…

Two models are considered for how people verify explicitly quantified sentences. To test the models, three reaction time experiments required subjects to verify statements quantified by some or all. The results show that some-statements took longer to verify than all-statements. (Author/DEP)

This paper reports an experiment designed to test theoretical relations among fast problem solving, more complex and slower problem solving, and research concerning fundamental memory processes. Using a cathode ray tube, subjects were presented with propositions of the form "Y is in list X" which they memorized. In later testing they were asked to…

To determine whether children's knowledge of arithmetic facts becomes increasingly "automatic" with age, 7-year-olds, 11-year-olds, and adults were given a number-matching task for which mental arithmetic should have been irrelevant. Specifically, students were required to verify the presence of a probe number in a previously presented pair (e.g.,…
