Front 12

Which evidence is most detrimental to the James–Lange theory?

Back 12

Patients with pure autonomic failure experience emotions.

Front 13

Which of the following is characterized by extreme sympathetic nervous system arousal?

Back 13

panic attack

Front 14

The Behavioral Activation System is associated with:

Back 14

low to moderate arousal, tendency to approach new objects, and pleasant mood.

Front 15

Impulsive behavior and poor decisions are common symptoms of:

Front 17

The term "serotonin turnover" refers to the amount of serotonin that is:

released at synapses and resynthesized.

Front 18

According to a number of animal studies, under which of the following conditions is the probability of violent behavior greatest?

Back 18

low serotonin turnover

Front 19

High levels of phenylalanine in the diet impair the synthesis of serotonin because it:

Back 19

Competes with an active transport mechanism shared by tryptophan.

Front 20

According to one hypothesis, if serotonin is released during aggressive behavior, then individuals with low serotonin release are more aggressive because of:

Back 20

increased serotonin receptor sensitivity.?
