Neuroticism
◦ aggressive, cold, egocentric, impersonal
◦ antisocial, unempathic, creative
◦ social, lively, active, assertive,
◦ carefree, dominant, surgent
◦ anxious, depressed, guilt-prone
◦ irrational, shy, moody emotional

Neuropsychologist

Basic theory:
◦ Personality based on the interaction of two systems
 Approach
 Inhibition

Approach System

Located in the Septal area and the lateral
hypothalamus

Causes one to be sensitive to potential
rewards and to be motivated to seek rewards

Inhibition system

Controlled by septo-hippocampus

Causes one to be sensitive to potential
punishments and to be motivated to avoid
those punishments





Added a third dimension
Flight or Fight system
Controls tendency to be aroused or
aggressive
Controlled by amygdala
Parallel to Eysenck’s “psychoticism”



Dopamine
Serotonin
Norepinephrine
Feeding, drinking, movement
Imbalanced dopamine activity can cause brain
dysfunction and disease.

Serotonin depletion:
Irrational anger, hypersensitivity to rejection,
pessimism, obsessive worry, fear of risk taking

Serotonin (5HT), many receptor subtypes

Hunger

Aggressive Behavior

Sleep Onset

Depression and OCD
◦ Too little 5Ht, increase in hunger (carbohydrates)
◦ Too little 5HT, violence, antisocial and suicidal behavior
◦ Too much 5HT, causes sleep
◦ Warm milk and turkey contain tryptophan (a precursor to Serotonin)
◦ Too little 5HT

Hypersecretion = too much hormone
Hyposecretion = too little hormone

2) mixed function (e.g., pancreas, thymus)

3) function not entirely known (e.g, pineal)

T3 and T4 are the major thyroid hormones
T4 = thyroxine

elevated body temperature, increased
appetite with weight loss, accelerated heart
