Motor Behavior
UNT Test #2 w/ Goggin
| Question | Answer |
|---|---|
| Primacy effect | info presented first |
| Position Effects | U-shape or inverted U-shape |
| Recency effect | info presented last |
| Long-Term Memory (LTM) | Unlimited in capacity and duration Practice leads to better and stronger LTM Riding a bicycle Affected by meaningfulness of information Rehearsal allows information to remain in LTM Must send information back to STM for retrieval |
| Short-Term Memory (STM) | Working memory (functional characteristics) Miller (1956)--limit to capacity of STM 7 + 2 items Phone number Information can be held in STM from 1-60 seconds Rehearsal, strategies to retain information Information lost through decay or interference |
| Short -Term Sensory Storage (STSS) | Sensory system (audition, vision, touch) Duration of less than one second Literal storage of information Recognition processes allow transfer of sensory information to STM Information lost through decay or interference |
| How is Memory Studied | Recall test-measure a student's ability to reproduce information Recognition test-measure a student's ability to select an answer among alternatives Savings test-measure a student's ability to relearn information faster than it was initially learned |
| Trace Decay Theory | Information is lost over time because of lack of use "Use it or lose it" Passive theory of forgetting |
| Inappropriate Retrieval Cues | Information is there, just not able to bring it forward |
| Interference Theory | Active theory of forgetting Memory is degraded by other events |
| Proactive Interference | Skill learned before interferes with the learning of a new skill |
| Retroactive Interference | Skill learned after a new skill interferes with the recall of the new skill |
| Encoding | The process of selecting stimulus information and representing it in a form that can be stored in memory Attentional mechanisms are important in encoding processes |
| Ways of testing attention | Dichotic Listening paradigm Cocktail Party Phenomenon Stroop Effect |
| Dichotic Listening paradigm | Present conflicting information in each ear One ear receives relevant information, other ear irrelevant information Process physical characteristics of irrelevant stimulus, but not meaning |
| Stroop Effect | Color/Word Effect Parallel processing in Stimulus Identification Difficulty comes in Response Selection in making a decision |
| Cranial vs. Caudal | head vs. tail |
| Superior vs. Inferior | above vs. below |
| Dorsal vs. Ventral | back vs. front |
| Ipsilateral vs. Contralateral | same side vs. opposite side |
| Axon | take information away from the cell body |
| Dendrite | take information toward the cell body |
| Sensory or Afferent Neuron | take information toward the Central Nervous System(CNS) from sensory mechanisms |
| Motor or Efferent | take information from the CNS to the muscles |
| Interneurons | connect sensory & motor neurons in the CNS |
| Impulse Transmission from Neuron1 to Neuron2 | Dendrite1 Cell Body1 Axon1 Dendrite2 Cell Body2 Axon2.... |
| Reflex Components | * Sensory receptor * Sensory or afferent Neuron * Spinal Cord * Motor or efferent Neuron * Muscle (motor unit) |
| Voluntary Action--Components | * Sensory receptor * Sensory or afferent neuron * Spinal Cord * Brain * Spinal Cord * Motor or efferent Neuron * Muscle (motor unit) |
