Identification and standardization of bilateral electrodermal parameters of learning abilities and disabilities.
Data are presented for identified and standardized bilateral electrodermal parameters of normal subjects with learning abilities and those with learning disabilities during cognitive workload in three different sessions. The electrodermal parameters are presented in terms of specific mumhos and represent the first identification and standardization of human abilities and disabilities. It was found that normal subjects had an electrodermal activity level which ranged between 6.5-8.5 mumhos bilaterally. Furthermore, 15 sub-groups of subjects with learning disabilities were identified based on their Left and Right electrodermal activity levels. They could be grouped under three main categories: (1) those subjects with lower than 5.01 mumhos Left and/or Right electrodermal activity level; (2) those with higher than 10.1 mumhos Left and/or Right activity level; and (3) those with mixed electrodermal activity having lower than 5.01 mumhos Left and/or Right activity in one session and higher than 10.1 mumhos activity in another session. These identified and standardized parameters have clinical implications and applications for the electrophysiological evaluation and psychophysiological treatment of learning disabilities.
