Integration of information was investigated in two experiments that employed a multiple observation, tilt discrimination task. The integration model of signal detection theory generally overestimated the improvement in discrimination resulting from additional observations. Further, probabilistic multiple responses proved detrimental to discrimination. These results differ from earlier findings using different discrimination tasks. Reasons for the differences were discussed. Author
