Dual space search during scientific reasoning

摘要: The purpose of the two studies reported here wos to develop an integrated model scientific reasoning process. Subjects were placed in a simulated discovery context by first teaching them how use electronic device and then asking discover hitherto unencountered function worked. To do this task. subjects had formulate hypotheses bas’ed on their prior knowledge, conduct experiments, evaluate results experiments. In t,he study, using 20 adult subjects, we identified main strategies that used generate new hypotheses. One strategy was scorch memory other generalize from previous We described former group as searching hypothesis space, latter experiment space. second with 10 adults, investigated search space instructing state all they could think conducting any Following phase, allowed who not correct rule generation phase discovered only generalizing experiments experimentol phase. Both provide support for view can be characterized problem spaces. By extending Simon Lea’s (1974) Generalized Rule Inducer, present general Scientific Discovery Dual Search (SDDS) shows spaces (an space) shapes generation, experimental design, evaluation also these processes interact each other. Finally, interpret earlier findings about psychology terms SDDS model.
