Figures & data

Table 1. Speech sound contrasts in terms of whether they share or differ for the features voicing and place of articulation

Table 2. Reaction times to right and left ear consonant–vowel contrasts differing in the features of voicing and place of articulation for the consistent and inconsistent strong handers

Figure 1. (A) Mean reaction times for the /ba /vs. /pa/ (voicing) contrast when presented to each ear for the consistent handers and the inconsistent strong handers. (B) The interaction between degree of hand preference and ear stimuli presented to when the consonant–vowel contrast involved place of articulation (/ba /vs. /ga/), with the inconsistent strong handers showing a faster reaction time for the right ear relative to the left (REA) while the consistent handers are not displaying the REA showing instead a longer reaction time for the right ear relative to the left. (C) An interaction again between degree of hand preference and ear stimulated when the contrast was place of articulation plus voicing (/ba /vs. /ka/).
