Behavior in the context of organs l.jpg
Behavior in the contextof organs

  • Organs are parts of organism …

  • Organs have specialized functions for survival of organism…

  • Organs include, most importantly, the human brain


Behavior in the context of organs4 l.jpg
Behavior in the contextof organs

  • Main area of research at organ level is the BRAIN

  • The brain is the organ of human behavior …

  • The brain, interacting with environmental influences, determines how we behave…


Behavior in the context of organs5 l.jpg
Behavior in the contextof organs

  • All environmental influences must be received via the senses, perceived, and processed by the brain before a person can behave.

  • Everything we smell, see, hear, taste, or touch is experienced in our brains.

  • No behavior occurs without sensory information being relayed to the brain.



Main brain functions l.jpg
Main Brain Functions

  • There are FIVE MAIN brain functions:

  • Sensation

  • Motion / Movement

  • Reproduction / Internal Regulation

  • Emotion

  • Thought / Cognition

  • Most important for crime?

Brain structure and process11 l.jpg
Brain Structure and Process

  • Brain can be divided into:

  • Cortex and Subcortex



Brain structure and process13 l.jpg
Brain Structure and Process

  • Cerebrum -- largest portion of cortex -- wrinkled mass in 2 hemispheres

  • Divided into FOUR LOBES

  • http://en.wikipedia.org/wiki/Cerebral_cortex


Brain structure and process14 l.jpg
Brain Structure and Process

  • Frontal lobe – thought, intellect, associations, planning, intent, inhibition/self control

  • Parietal lobe – works with frontal lobe, movement, sensation

  • Occipital lobe – vision, abstract concepts

  • Temporal lobe – hearing, learning/memory, autonomic response, regulation of hormones, emotion, aggression

Obviously then …

  • The parts most important for criminal behavior are frontal lobes and temporal lobes

  • Thus, overactive temporal lobe or underactive frontal lobe can result in “bad” behavior …
