Chapter 15: Problem 10

Research indicates that the symptoms of OCD _____ a. are similar to the symptoms of panic disorder b. are triggered by low levels of stress hormones c. are related to hyperactivity in the orbitofrontal cortex d. are reduced if people are asked to view photos of stimuli that trigger the symptoms

Short Answer

Expert verified
c. The symptoms of OCD are related to hyperactivity in the orbitofrontal cortex

Step by step solution

01

Understand what each choice implies

Each choice implies a different aspect or cause of the symptoms of OCD. Some choices imply a similarity to another disorder, a role of stress hormones, a neurobiological cause, or a potential method of reducing symptoms.
02

Compare choices to known information about OCD

Using knowledge or research on OCD, each statement should be compared to what is known about the disorder. The brain area mentioned, the orbitofrontal cortex, has been linked to OCD, which makes choice c a likely answer. However, all options need to be considered.
03

Eliminate incorrect choices

It is known that OCD and Panic Disorder are distinct disorders with separate symptoms, so choice a must be incorrect. There is no evidence that low levels of stress hormones trigger OCD, so choice b can be eliminated. Viewing triggering stimuli tends to increase, not reduce, OCD symptoms, so choice d is not correct.
04

Choose the correct answer

After comparing all options to known information about OCD and eliminating the choices that are clearly incorrect, the remaining choice, 'c. are related to hyperactivity in the orbitofrontal cortex', is chosen as the correct answer.
