Abstract: | Summary The present set of studies attempted to replicate Gellatly's (1985) findings that were supportive of Evan's (1982) hypothesis that the right hemisphere produces a selective bias towards the incorrect solution of a complex reasoning task. Subjects solved problems of the form if p then q. In four studies, participants simultaneously performed a bottle - balancing task on each hand to interfere with processing of the reasoning task in the right hemisphere. In the fifth study, the bottle - balancing task was replaced by a finger - sequencing task. The results of the five studies did not show that the interference with right-hemisphere activity resulted in better performance on the conditional-reasoning task. It is concluded that the hypothesis of a right-hemisphere bias in conditional reasoning is still in need of reliable findings. |
