Many adjectives for musical timbre reflect cross-modal correspondence, particularly with vision and touch (e.g., “dark–bright,” “smooth–rough”). Although multisensory integration between visual/tactile processing and hearing has been demonstrated for pitch and loudness, timbre is not well understood as a locus of cross-modal mappings. Are people consistent in these semantic associations? Do cross-modal terms reflect dimensional interactions in timbre processing? Here I designed two experiments to investigate crosstalk between timbre semantics and perception through the use of Stroop-type speeded classification. Experiment 1 found that incongruent pairings of instrument timbres and written names caused significant Stroop-type interference relative to congruent pairs, indicating bidirectional crosstalk between semantic and auditory modalities. Pre-Experiment 2 asked participants to rate natural and synthesized timbres on semantic differential scales capturing luminance (brightness) and texture (roughness) associations, finding substantial consistency for a number of timbres. Acoustic correlates of these associations were also assessed, indicating an important role for high-frequency energy in the intensity of cross-modal ratings. Experiment 2 used timbre adjectives and sound stimuli validated in the previous experiment in two variants of a semantic-auditory Stroop-type task. Results of linear mixed-effects modeling of reaction time and accuracy showed slight interference in semantic processing when adjectives were paired with cross-modally incongruent instrument timbres (e.g., the word “smooth” with a “rough” timbre). Taken together, I conclude by suggesting that semantic crosstalk in timbre processing may be partially automatic and could reflect weak synesthetic congruency between interconnected sensory domains.

Adult humans spontaneously associate visual features, such as size and direction of movement, with phonetic properties like vowel quality and auditory pitch. A number of recent studies have claimed that looking time in preverbal infants reveals the same associations, which would indicate that some cross-modal correspondences are the result of perceptual biases. Here we tested 30 infants of age 7-13 months, who were exposed to pairs of audiovisual stimuli presented first sequentially and then side by side. The stimuli consisted of a visual object (computer-animated ball or filmed human hand) moving sinusoidally, vertically, or in a U-shape and accompanied by a sliding voice-like tone. Sequential presentation revealed no preference for either audiovisual synchrony or synesthetic congruency, while side-by-side presentation revealed a small preference for incongruent stimuli. The effect of congruency was similar for the animated ball and filmed human hand. These findings extend the results of previous research on pitch-motion synesthesia in preverbal infants, which used animations and sliding whistles, to more ecologically relevant stimuli such as voice and gestures. If infants and adults share the same preferences for non-arbitrary mappings between manual gestures and intonation, this could indicate that cross-modal correspondences facilitate language acquisition. On the other hand, a critical survey of the field revealed that previous studies of audiovisual cross-modal correspondences in infants suffer from replication failures due to poor robustness of the reported effect with respect to experimental stimuli and testing procedure. We therefore argue that the research on cross-modal correspondences in infants would profit from using alternative testing methods in addition to preferential looking and call for replication of previously reported congruency effects.
