Hypothetical constructs
o Variables are Constructs
o We’ll use these terms interchangeably throughout the semester
o The nature of constructs
 Definition cannot be exhausted
 Multiple ways of measuring each Construct
 To say “This is self-esteem” would be reductionistic
 Theory is simple a collection of well organized constructs that are expected to relate to each other in particular ways
Operational Definition
o OD-a specific definition of a construct in terms of the operations or techniques researchers use to measure or manipulate it
o Specific way of measuring a construct
o Help us communicate ideas to others ore effectively
o Concrete definitions allow us to gather data and obtain numerical values
Frontal Lobes
Involved in speaking and muscle movements and in making plans and judgments
Parietal Lobes
Include the sensory cortex; spatial abilities
Occipital Lobes
Include the visual areas, which receive visual information from the opposite visual field
Temporal Lobes
Include the auditory areas
PARTS of a nerve
a. Dendrite
b. Cell body
c. Axon
d. Synapse
The bushy, branching extensions of a neuron that receive messages and conduct impulses toward the cell body
The extension of a neuron, ending in branching terminal fibers, through which messages are sent to other neurons or to muscles or glands
Myelin Sheath
o A layer of fatty cells segment encasing the fibers of many neurons
o Enable vastly greater transmission speed of neutral impulses
o Junction between the axon tip of the sending neuron and the dendrite of cell body of the receiving neuron
o Tiny gap at this junction is called the synaptic gap or cleft
⬢ Affect
⬢ Behavior
⬢ Cognition
⬢ Physical
⬢ Affect
o Happy; Depressed
⬢ Behavior
o Aggression; disclose; trust
⬢ Cognition
o Logical; linear thought; confusion
⬢ Physical
o The “little brain” attached to the rear of the brainstem
o It helps coordinate voluntary movement and balance
MRI and CT are similar because...
they both allow us to see structures within the brain
electrical activity
A visual display of brain activity that detects where a radioactive form of glucose goes while the brain performs a given task
Chemical and Electrical energy
o Chemical messengers that traverse the synaptic gaps between neurons
o When released by the sending neuron, neurotransmitters travel across the synapse and bind to receptor sites on the receiving neuron, thereby influencing whether it will generate a neural impulse
Case study
• Examine an individual inn depth
• Like a biography
• Freud’s major technique
• Phineas Gage-railroad worker who struck something that exploded and something went into his front lobe of his brain
• Erickson
o Gandhi
o Luther
