Neurophysiology -
MBD (minimal brain dysfunction)
May be manifested in episodes of rage associated with child and spousal abuse, suicide, homicide
Common in prison populations
Arousal Theory
- Too much arousal causes anxiety, too little causes boredom
“Sensation seekers”
Require high levels of stimulation, seek our exciting activities
May include criminal & violent activities
Level of arousal may be result of
Brain chemistry, number brain cells with neurotransmitter, receptor sites, heart rate
Evolutionary Views of Crime
1) Aggression facilitates dominance over scarce resources
- Provides advantage in survival and reproduction
2) Gender differences in reproduction encourage aggression in males
- More sexual partners, more offspring
- Aggressive males have greater impact on gene pool
- Accounts for jealousy, war, spousal abuse

2) Severity of punishment
3) Celerity (speed) of punishment
Why Death Penalty Is Ineffective

Convicted criminals
Can Incapacitation Deter Crime?
Structural Theories of Violence
Basic Perspectives
Social Structure Theories - Strain Theory
Barriers to achievement create frustration and anger, resulting in crime
