Abstract

An audiovisual correspondence (AVC) refers to an observer’s seemingly arbitrary

yet consistent matching of sensory features across the two modalities; for

example, between auditory pitch height and visual height or visual size. Research

on AVCs frequently uses a speeded classification procedure in which participants

are asked to rapidly classify the pitch of a sound accompanied either by a

congruent or an incongruent visual object (e.g., high pitches are congruent with

higher/smaller visual objects and incongruent with lower/larger visual objects).

To investigate the strength of these pitch AVCs (height, size, spatial frequency,

brightness, sharpness), trials where the height AVC competed with each other AVC

in terms of pitch congruency were created. For example, when classifying pitch

height, participants were presented with trials where both visual height and size

were congruent or incongruent with pitch; additionally, there were trials where

height was congruent but size was incongruent (i.e., high pitch matched with

large object at high height) and trials where size was congruent but height was

incongruent (i.e., high pitch matched with small object at low height). Based

on previous work, congruency between pitch and height was expected to be

more important than congruency between pitch and spatial frequency, brightness,

sharpness, or size. As predicted, in all four studies, RTs when only height was

congruent were just as fast as when both dimensions were congruent. In contrast,

RTs when only spatial frequency, brightness, sharpness, or size was congruent

(and height was incongruent) were just as slow as when both dimensions were

incongruent. These results reinforce the superiority of the pitch-height AVC and

can be interpreted based on the metaphor used for pitch in English, showing the

importance of semantic/linguistic effects to understanding AVCs.
