Polarity correspondence effect between loudness and lateralized response set.

Chang S, Cho YS - Front Psychol (2015)

Bottom Line: Performance is better when a high pitch tone is associated with an up or right response and a low pitch tone with a down or left response compared to the opposite pairs, which is called the spatial-musical association of response codes effect.In Experiments 1 and 2, in which participants performed a loudness-judgment task and a timbre-judgment task respectively, the correspondence effect was obtained between loudness and response side regardless of whether loudness was relevant to the task or not.The results suggest that loudness produced polarity codes that influenced response selection (Experiments 1 and 2), and additional spatial codes provided by stimulus position modulated the effect, generating the stimulus eccentricity effect (Experiments 3 and 4), which is consistent with the polarity correspondence principle.

ABSTRACT
Performance is better when a high pitch tone is associated with an up or right response and a low pitch tone with a down or left response compared to the opposite pairs, which is called the spatial-musical association of response codes effect. The current study examined whether polarity codes are formed in terms of the variation in loudness. In Experiments 1 and 2, in which participants performed a loudness-judgment task and a timbre-judgment task respectively, the correspondence effect was obtained between loudness and response side regardless of whether loudness was relevant to the task or not. In Experiments 3 and 4, in which the identical loudness- and timbre-judgment tasks were conducted while the auditory stimulus was presented only to the left or right ear, the correspondence effect was modulated by the ear to which the stimulus was presented, even though the effect was marginally significant in Experiment 4. The results suggest that loudness produced polarity codes that influenced response selection (Experiments 1 and 2), and additional spatial codes provided by stimulus position modulated the effect, generating the stimulus eccentricity effect (Experiments 3 and 4), which is consistent with the polarity correspondence principle.

Figure 2: Mean reaction times (RTs) as a function of loudness and response side in Experiment 1 are shown along with their SE.

Mentions: The main effect of loudness was significant, F(1,15) = 7.95, p = 0.0130, MSE = 628, = 0.23. The mean RT was shorter for high-level loudness tones (M = 343 ms) than low-level loudness tones (M = 361 ms). The main effect of response side was also significant, F(1,15) = 6.15, p = 0.0255, MSE = 293, = 0.10, showing that responding with the right hand (M = 346 ms) was faster than with the left hand (M = 357 ms). Of importance, a significant interaction between loudness and response side was obtained, F(1,15) = 4.76, p = 0.0454, MSE = 1,098, = 0.24, indicating a correspondence effect between loudness and response side. The mean RT was shorter with loud-right/soft-left mapping (M = 343 ms) than loud-left/soft-right mapping (M = 361 ms; see Figure 2).
