Abnormal PsychologyPsychological Disorders

Before we begin…• Be careful about joking about

psychological disorders… You are not OCD just because

you like your hands clean.

• People-centered language Please be compassionate!

Depression: Cognitive Errors• Sadder-but-wiser effect

a negative way, focus on the negative aspects of any situation, and has pessimistic expectations of the future

• College student effect College students are at a much

higher risk for depression due to drastic life changes; those who go in with both realistic expectations and optimism succeed most

Why? Biological perspective

Depressed brain Lack of norepinephrine and

serotonin Less good Omega-3 fatty acids

emotions) inactive Hippocampus vulnerable to

stress-related damage Genetic influences

I can compose melodies without effort. I can paint…I feel pleasure, a sense of euphoria or elation. I want it to last forever. I don’t seem to need much sleep. I’ve lost weight and I feel healthy, and I like myself. I’ve just bought six new dresses, in fact, and they look quite good on me. I feel sexy and men stare at me. Maybe I’ll have an affair or perhaps several.”
