Injecting a person with an excitatory chemical that activates the sympathetic nervous system is likely to increase his or her subjective experience of intense fear and anxiety. Use one of the major theories of emotion to account for the effects of this chemical on a person's emotional state.
Which theory of emotion would have the greatest difficulty explaining these effects?

a. James-Lange theory
b. Cannon-Bard theory
c. Two-Factor theory

Research students should note that the Cannon-Bard theory would have the most difficult time explaining the increase in fear produced by the chemical.

Explanation: Research students can use any of the theories of emotion to discuss the possible effect of this chemical:-

James-Lange theory:- the chemical would intensify his or her physiological response, which in turn would intensify the experienced emotion.

Cannon-Bard theory:- the physiological change might be increased by the chemical but that would not affect the experienced emotion.

Two-factor theory :- the chemical would intensify the physiological response, which would change the cognitive label applied.

an aneroid barometer is different from a mercury barometer in that it provides readings that increase as air pressure increases.
