The present study examined the effects of imposed monitoring and blunt
ing coping strategies on emotional reactivity in 40 subjects who prepa
red themselves for upcoming neutral and aversive slides. Besides subje
ctive indices, electrodermal measures and eye blink startle responses
were used to evaluate the effect of preparatory strategies. In order t
o investigate whether effects of strategies are modulated by individua
l differences in coping style, habitual monitoring was assessed with t
he Miller Behavioral Style Scale (MBSS, Miller, 1987). It was found th
at monitoring instructions resulted in higher levels of subjective anx
iety during the anticipation of aversive slides than blunting instruct
ions. In addition, when confronted with the frightening and neutral st
imuli, monitoring instruction subjects showed smaller electrodermal re
activity than blunting instruction subjects. These effects were not fo
und to be modulated by habitual coping style. Overall, the startle mea
sure yielded no meaningful effects. Taken together, the results seem t
o indicate that emotional reactivity under threatening conditions is m
ore affected by imposed coping strategies than by habitual coping styl
es as indexed by the MBSS.
