This study investigated the effects of positive and negative reinforcement on superstitious behaviors. Participants were instructed to produce the word "GOOD" on a computer display (positive reinforcement condition) or to remove the word "BAD" (negative reinforcement condition) by pressing any of six keys. The words GOOD or BAD were presented at fixed-time intervals regardless of the participant's responses. In Experiment 1, only participants exposed to the negative reinforcement condition acquired superstitious behaviors. However, the observed asymmetry may not have been due to the polarity of consequences (positive vs. negative) but instead to the amount of time of goal states, because the period of the absence of BAD was longer than the period of the presence of GOOD. Experiment 2 varied the duration of word presentations to match the period of goal state between the positive and negative reinforcement conditions, and found that participants acquired superstitious behaviors equally under the two conditions. These results indicate that the duration of a consequence rather than its polarity is a critical factor controlling superstitious behaviors. The theoretical relationship between superstitious behavior and the illusion of control is discussed.

People prefer unambiguity to ambiguity in decision making under ambiguity. This phenomenon, known as “ambiguity aversion,” is thought to be influenced by environmental and psychological factors. The present research demonstrated the effects of choice opportunity (the availability of choice of cards), competition (the presence vs. absence of a competitor), and stimulus familiarity (familiar playing cards vs. unfamiliar tarot cards) on choice of ambiguity. Participants preferred the ambiguous deck of cards when they were allowed to choose playing cards. In the tarot-card task, however, they did not show a preference for the ambiguous deck even if they could choose the cards by themselves. The competition factor had no effect on the participants' choice. These findings indicate that choice opportunity and stimulus familiarity affect decision making under ambiguity.
