Lindberg, L-Å., and Brehmer, B. Effects of task information and active feedback control in inductive inference. Umeå Psychological Reports No. 123, 1977. - Learning of an inductive task with one linear and one quadratic cue was investigated in a 2 (levels of task information: maximum vs. minimum) x 2 (control of outcome feedback: active vs.passive) x H (blocks of trials) factorial experiment. In the maximum information condition subjects were given the criterion distribution, including the mean, for each combination of cue values. Under the active feedback condition subjects selected cue combinations and feedback instances in whatever order they wanted. Positive effects of all three factors were obtained with respect to subjects'selection of inference rules and level of task control. It was concluded that subjects' inconsistency under ordinary outcome feedback conditions is due in part to lack of memory capacity and in part to the fact that subjects are prevented from active hypothesis testing. However,these factors do not fully explain the lack of consistency as shown by the fact that subjects under the present maximal information/active feedback condition did not reach the maximal level of task control, although they used the optimal inference rules.
