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
• Behavior • Cognition • Physical |
• 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 o Luther |
