According to the National Research Council, painful work-related upper limb disorders are caused by different pathophysiological mechanisms, one of which is repetitive strain injury (RSI). Forearm pain, tenderness, and paresthesias are thought to result from a continual risk of exceeding limits of "cumulative trauma load tolerance" (CTLT, cf. NRC 2001) in… (More)
To test Levonian's retentivity-accessibility hypothesis on arousal and retention 48 undergraduates participated in an experiment on retention while skin resistance was recorded. Results support Levonian's hypothesis only for longer-term (30-min.) retention but not for short-tem (3-min.) retention.
Eighty students were trained on a maze-like ballboard over a series of 24 trials, while the skin impedance level was recorded from the palmar and dorsal sides of their fingers. A principal component analysis of the cross-products for the palmar and dorsal data treated separately resulted in two components for the palmar data (55% and 25% of variance) and… (More)
