Individual consistencies across time and tasks: A replication of interactive styles

Three experimental studies were carried out in order to find within-subject consistencies as well as individual differences in a concurrent choice situation involving risk-taking. Four subjects were exposed twice, with a 4-month delay, to a horse-race game and a stock-exchange game, in order to evaluate their choices for a conservative versus a risky condition under open contingencies. The results in the 3 experiments showed reliable profiles in all subjects when frequency of changeovers was correlated with number of accumulated earnings. Results are discussed in terms of interactive styles.
