Unit 3 Physiological Psych Flashcards

Emotions

• consist of behavior and autonomic responses

Autonomic Responses

• involuntary regulation (heart rate, bodily fluids, etc.)

• sympathetic nervous system arousal (flight or flight)

2 Emotional Experiences:

• James Lange Theory

• Cannon Bard Theory

James Lange Theory

• stimulus is: autonomic arousal and muscle tension cause emotions

• perception of emotion leads to a label

• Spinal cord injury = less emotion

• Ex. I feel afraid because I tremble,

Cannon Bard Theory

• Stimulus is: autonomic arousal, muscle tension, and emotional all at once

• all factors cause effect of stimulus on the brain

• Ex. the dog made me tremble and I feel afraid

Locked In Syndrome

• damage to brainstem

• no motor function

• absence of:

  • body movement

  • emotionality

  • sensation

Hormone responses to stress (threat)

• hypothalamus → anterior pituitary glad → adrenal cortex (IN THIS ORDER)

• have to have one release before the other can

• elevates blood sugar and metabolic rate,

• prepares body to respond

Hypothalamus

• located in forebrain

• coordinates both the autonomic nervous system and the activity of the pituitary

• controls body temperature, thirst, hunger, and other homeostatic systems, and involved in sleep and emotional activity.

• releases corticotropin (CRF)

• releasing factor

anterior pituitary gland

• releases adrenocorticotropic hormones (ACTH)
