1. This Eeorandu contains a recommendetion for your approrel. The reccmmendation is contained in Peragrnph 7.

2. The Galvanic Skin Response (G.S.R.), reflecting elcctrical changcs in the skin, has been used trcditionally es a stress indicator in the polyereph interview end is ccnsidered e prianry psychonhysiological indicator. Despite the enpbesis placed upon this neasurenent, only recently hes an cplonation of ite functionel relationship to stress started to cerçe. The electrical changes in the ckin are comlex in nature, beins produced ty severel interectins physiolcgical mechanisns. As c result, the interpretive uscfulness of this neasurement is limited. Prior vors,for vhici this ia & fcllov-on effort, was concered with the analysis end oroanizaticn of the physiolcgical processes underlying the G.S.R. As a result of thia work, nev relationshirs have been developed which eurpport the contention that the electroderal systca has two componente wiich my runction soth synergistically and ináependantly. As a result, a rationale lor G.S.R. interpretation has been developed vhich has shoim evideace of behavioral specificity. This folloy-on study is directed primarily tovard an cdeptation of thcse new fincings to the polygraph intervieu for the purpose or enhancing the utility of the G.S.2.

3. The rescarch, detailed in the accompamyins proposel, vill be part of the Stress licesurement prcgrea and io Coal-oricnted touard the polyerapb. As outlined, these inveotigations fell into the follcring erees:

a. Develctaent of behaviorel correlants to new electrodcrmal neesurements.

b. Anclysis of the relationship betucen the electroueral cystca cnd orin blood flow.

These studies represent e netural extensien end exploitation of eerlier investicatious into akin physioloy. As a result of cnrlier vore, the risk associstcd vith this contrect is considcred small. The contructor vill celiver e final report end cuch interim reports es may be requested by the Project Orficer.
