- 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 - Dendrite
- The bushy, branching extensions of a neuron that receive messages and conduct impulses toward the cell body
- Axon
- 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 - Synapse
-
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
o Happy; Depressed
⬢ Behavior
o Aggression; disclose; trust
⬢ Cognition
o Logical; linear thought; confusion
⬢ Physical - Cerebellum
-
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
- EEG
- electrical activity
- PET
- 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
