Study Notes
Biological Psychology
- Biological psychologists study the biological basis of behavior
- Biological psychologists are also known as Physiological psychologists
Human Brain
- The brain controls thought, feelings, and behavior
- Behavior is dictated by biology
- Different parts of the brain perform different functions
Lobes of the Brain
- The cerebrum is divided into four lobes: parietal, frontal, occipital, and temporal
- The cortex in humans is more wrinkled and convoluted than other animals, indicating higher development
- Each hemisphere has several large lobes separated by fissures
Motor Area
- Controls voluntary behavior of the body
- The body is represented on the motor area in an upside-down or opposite manner.
- The motor area is part of the motor cortex
Somatosensory Area
- Produces sensory experience, such as heat, cold, touch, pain, and the sense of body movement
- The sense on one side of the body is controlled by the somatosensory area on the opposite side.
Visual Area
- The optic nerve transmits visual information from the retina to the brain.
- Optic nerves from the right eye go to the right hemisphere, and cross over at the optic chiasma to the left hemisphere. This is the same pattern for the left eye.
Auditory Area
- Responsible for processing sounds
Language Area
- Broca's Area: Located in the frontal lobe of the left hemisphere; responsible for fluent and smooth speech; if damaged, Broca's aphasia occurs (cannot control the actual production of words, speech halts, and words are often mispronounced).
- Wernicke's Area: Located in the temporal lobe of the left hemisphere; responsible for understanding the meaning of words; if damaged, Wernicke's aphasia occurs.
Connection of the Two Hemispheres: Corpus Callosum
- Corpus Callosum is a broad band of connecting nerve fibers
- Epileptic seizures can be a result of disruption within this band
- Split-brain surgery is a way to decrease the severity of such seizures.
Functions of Left Hemisphere
- Language ability
- Complicated logical and analytical activities
- Complicated mathematical computation
- The right hemisphere is not as specialized in performing these functions
Functions of Right Hemisphere
- Spatial and pattern perception
- Identification of face and facial expression
EEG Studies
- Studies using EEG (electroencephalogram) support the differentiated specialized functions of the left and right hemispheres which is measured by brain wave activity
- Verbal tasks activate the left hemisphere more
- Spatial tasks activate the right hemisphere more
