520    The present study examined the relation of FH of 
       cardiovascular disease to resting blood pressure and 
       multidimensional responses to stress including cognitive 
       appraisals, affective responses, state related measures of
       appetitive and aversive motivation, and cardiovascular 
       reactivity among Mexican Americans during clearly 
       appetitive, clearly aversive, and combined appetitive/
       aversive stress tasks. Hypotheses were based on review of 
       existing literature and in part on a pilot study examining
       Mexican Americans' stress responses which suggested that 
       FH+ Mexican Americans may be predisposed toward greater 
       BAS sensitivity whereas FH- Mexican Americans may be 
       predisposed toward greater BIS sensitivity. The specific 
       aims of this study were to examine the relationship of FH 
       in Mexican Americans to (a) baseline cardiovascular 
       activity, (b) stress-related cardiovascular reactivity, 
       (c) BIS and BAS tendencies during appetitive, aversive and
       combined appetitive/aversive stress situations, and (d) 
       generalization of BIS and BAS response tendencies across 
       tasks of differing in motivational orientation. Results 
       indicated that FH+ individuals exhibited greater DBP and 
       lower SV at rest, results that were attributable to higher
       TPR at rest, than FH- individuals. This finding suggests 
       early development of sustained hypertension among this 
       group. The results from the state-related measures of BIS 
       and BAS activation, appraisal data, and intercorrelations 
       of HR, PEP, and TPR task reactivity supported the 
       hypothesis that FH+ Mexican Americans respond to stress 
       with greater Appetitive tendencies compared to FH- Mexican
       Americans, and that these tendencies generalize across 
       tasks differing in motivational orientation. Implications 
       for future research are discussed
