It is not an either/or question. The coefficient for a dummy variable
shows you the status of one group relative to the other. In your case, one
gender scores 1.67 points lower than the other (or, if you prefer, one
gender scores 1.67 points higher than the other). Which one is
higher/lower depends on how gender is coded.
In regression analysis, how do we interpret dichotomus
variables...How would I know if it is male or female which accounts
for decrease in blood flow.
To put it another way, it wouldn't make any sense to talk about an effect
of gender if your sample only had one gender. If males have higher scores
it automatically follows that females have lower scores. You don't say
that one gender has an effect on blood flow while the other does not.
For brief discussions of dummy variables, see pp. 10-12 of
Or (see especially pp. 8-9)
