Interhemispheric transmission times (IHTTs) were calculated for 33 right-handed subjects. Verbal and manual response times (RTs) were recorded to visual stimuli exposed in either the left or right visual fields (LF, RF) for 50 msec. Each subject received 15 stimuli (dots) in the LF (1.5 degrees to the left of fixation), 15 stimuli in the RF, and 15 blank trials in both the verbal and manual response condition. IHTTs were calculated for each subject by subtracting the mean RF RT (I.E., uncrossed path) from the means LF RT (i.e., crossed path). Results indicated a nonsignificant IHTT obtained under the manual response condition of 5 msec and a highly significant IHTT obtained under the verbal response condition of 20 msec. While no significant correlation was found between IHTTs obtained under both response conditions, high correlations were found between component RT measures (i.e., manual RF RT, manual LF RT, verbal RF RT, and verbal LF RT). Thus, IHTT is independent of simple RT.
为33名右利手受试者计算了半球间传输时间（IHTT）。记录了对左视野或右视野（LF，RF）中呈现50毫秒的视觉刺激的言语和手动反应时间（RT）。每个受试者在左视野（注视点左侧1.5度）接受15次刺激（点），在右视野接受15次刺激，并在言语和手动反应条件下各接受15次空白试验。通过从平均左视野反应时间（即交叉路径）中减去平均右视野反应时间（即未交叉路径），为每个受试者计算IHTT。结果表明，在手动反应条件下获得的IHTT为5毫秒，无显著差异；在言语反应条件下获得的IHTT为20毫秒，具有高度显著性。虽然在两种反应条件下获得的IHTT之间未发现显著相关性，但在各成分反应时间测量值（即手动右视野反应时间、手动左视野反应时间、言语右视野反应时间和言语左视野反应时间）之间发现了高度相关性。因此，IHTT独立于简单反应时间。
