1. Types of Memory - ANSWER 1. Short term "working" memory
- Temporary storage and manipulation
- Holds information in mind long enough to complete a task
- Limited capacity and duration (seconds)
- Verbal/visuspatial/motor
2. Long term memory
- Requires encoding, storage, retrieved
- Large but limited capacity
- Semantic / episodic / procedural
2. Selection and Prioritization - ANSWER 1. Human information processing capacity is limited so
process information selectively
How do we select and prioritize information to process?
- Limited capacity
- Attention can be shifted
- Attention can be divided
,3. Cognitive Processing - ANSWER 1. Attention can be shifted
- Voluntary or reflexive
2. Resources can be divided, but...
3. Capacity is limited (demands > resources)
4. What do motor programs specify? - ANSWER 1. Which muscles involved
2. Order of muscles involved
3. Relative forces of each muscle
4. Relative timing and sequencing of contractions
5. Duration of each contraction
5. Output of information processing - ANSWER 1. Open-loop system
- Output based solely on motor program (short, fast mvt - shoting basketball)
2. Closed-loop system
- Results of output fed back into the system if it does not achieve desired goal
- Error detection -> corrective responses
6. Factors affecting reaction time: Response selection - ANSWER 1. Number of alternative
responses
- RT increases as the number of alternatives increases
- Simple RT (only 1 possible solution) vs. choice RT (2+ possibilities)
- Hick's Law (Choice RT) = increasing number of choices increase RT
- sports
2. Stimulus-response compatibility
- RT is faster when stimulus and response correspond
- if not, may affect accuracy
- ex. Switch up = "on"/down = "off"
, 3. Response complexity
- more complex response =
more muscles involved
- increased RT
- design technology (phone settings)
4. Practice decreases RT
a) Stim. Identification: identify and recognize quicker
b) Response Selection: better awareness on possible options and knowing which is most effective
c) Response Programming: increased efficiency is specifying response parameters
- using in context-specific practice
7. Stroop Effect - ANSWER Explains the decreased speed of naming the color of ink used to print
words when the color of ink and the word itself are of different colors - Distractor interference
2. Dendrites - postsynaptic membrane (receive info from synapse)
3. Myelin - enhance speed and efficiency of communication
4. Ranvier nodes - speeds up neural transmission
5. Terminal branches (presynpatic membrane) - neurotransmitter released into next synapse
9. Structures of CNS - ANSWER 1. Brain
- forebrain
- midbrain
- hindbrain
2. Spinal Cord
