ELECTRODERMAL AND ELECTROMYOGRAPHIC PARAMETERS IN CONCEPT IDENTIEICATION
Vladimir Pishkin, Jay Talmadge Shurley · Psychophysiology · 1968
ABSTRACT This study examined concept identification (CI) performance as a function of physiological arousal and physiological activity as a function of task complexity and expectation of success or failure. The development of an unsolvable set constituted stresses used to manipulate arousal. Results showed the following: (1) a positive correlation between CI errors and muscle action potential (MAP), (2) a negative correlation between spontaneous GSRs and MAP, (3) a greater number of spontaneous GSRs in low complexity‐solvable set CI as compared with high complexity problems, (4) progressively improving CI performance in low complexity‐solvable set problems, (5) increase in MAPs with high complexity‐unsolvable set CI. These findings were interpreted as indicating that MAP reflects internal disturbance associated with inability to process information while spontaneous GSRs reflect successful information intake.
