ABSTRACTThe role of sweat gland activity in the mediation of skin potential and skin conductance levels was investigated.l‐Hyoscyamine was introduced into the fingertips by iontophoresis to eliminate sweat gland activity, andd‐hyoscyamine, an inert analog of thel‐isomer, was used as a control for ion size. Neostigmine was used to potentiate sweating.l‐Hyoscyamine significantly decreased skin conductance level and the number of active sweat glands and reduced the negativity of skin potential level, but neostigmine, which promoted sweating and skin conductance, did not increase the negativity of skin potential. The lowering of skin potential on the denervated hand of a hemi‐sympathectomized patient was found to be similar in magnitude to the decrease in skin potential due to pharmacological elimination of sweat gland activity. The results are discussed in relation to hypotheses concerning the mechanism of skin

摘要:

ABSTRACTAn experiment was designed to examine the role of lying behavior, per se, as the basis for experimental psychophysiological detection of deception. In addition to the standard card‐test procedure, a second procedure required the S to say “yes” to every question posed relating to the card chosen. This variation involved telling the “truth” in respect to the critical card in contrast to the usual procedure in which he is required to “lie.” With the use of the galvanic skin response (GSR)channel, significant detection rates were obtained for both procedures with nosignificant difference between them. Some theoretical issues related to the findings

摘要:

ABSTRACTA solid‐state Schmitt trigger has been designed with the aim of providing reliable triggering at ± 5 v on any input waveform. Input impedance is high; hysteresis, rise and fall times, and circuit delay are extremely short. Power consumption is small. Power supply ripple and instability are eliminated by the use of a battery power pack. Construction time, cost, and technical difficulties are reduced with a solid‐state encapsulated mo
