Abstract [en]

Two experiments were performed to study effects of modality, temporal position, and their in- teraction on comparisons of successive stimuli. In Experiment 1, intramodal (tone-tone and line-line) and crossmodal (tone-line and line-tone) stimulus pairs, with two interstimulus in- tervals (ISIs), were presented. Participants indicated which stimulus was the “stronger.” Time-order effects (TOEs) were studied using the classic D% measure as well as weighting coefficients from Hellström’s sensation weighting model. TOEs were found in both intramo- dal and crossmodal comparisons. The classic pause-function (more negative TOE with longer ISIs) was found in all pair types except tone-line. In Experiment 2, participants indicated which of two lines was the longer, or which of two tones was the louder. Intramodal anchors, crossmodal anchors, or no anchors were interpolated between the stimuli. Anchoring tended to yield negative TOEs and to diminish the first stimulus’ weight. Intramodal anchoring of tone-tone pairs yielded low stimulus weights, suggesting stimulus interference.
