Midterm 2 Flashcards
Lecture 10:
What is Attention?
characteristics that establish limits to skill performance
- attention limits influence performance when we do more than one activity at the same time
Lecture 10:
What happens to attention when multitasking?
When simultaneously performing multiple tasks, we experience no performance difficulties but we cannot do all the tasks as well as we wish to
Lecture 10:
What are the 3 theories of attention?
1.) Filter Theory
2.) Central-Resource Capacity Theories of attention
3.) Kahneman’s Attention Theory
Lecture 10:
What is the Filter Theory/Bottleneck Theory of Attention?
Explains the difficulty with doing multiple tasks at one time because of the inability to serially process multiple stimuli
- Focusses on the task only
Lecture 10:
What is the Central-Resource Capacity Theories of Attention?
Propose one central source of attentional resources for which all activities requiring attention compete against
- divides attention amongst many tasks
Lecture 10:
What is Kahneman’s Attention Theory?
Attention viewed as cognitive effort related to the mental resources needed for specific activities
Lecture 10:
In Kahneman’s Attention Theory, what determines the amount of attention capacity available?
Amount of attention capacity available is determined by arousal levels.
- if arousal level is high, than attention capacity will increase
- to have maximal attention resources available, a person must be at an optimal arousal level
Lecture 10:
Based on Kahneman’s Attention Theory, what are the 3 rules people use when al;locating attention resources?
1.) Allocate attention to ensure completion of atleast 1 task
2.) Enduring Dispositions - involuntary attention given to atleast 2 characteristics of events (event is meaningful)
3.) Momentary Intentions - allocate attention according to one’s specific intentions
Lecture 10:
What are Multiple Resource Theories?
Opposite of central resource theories
- propose we have several resources for attention, each with a limited capacity.
Lecture 10:
For Multiple Resource Theories, what do the multiple sources need?
Multiple sources based on specific information processing need…
- input & output modalities
- stages of information processing
- codes of processing information
Lecture 10:
When discussing the Multiple Resource Theory; what does the success of performing 2+ tasks depend on?
depends on whether tasks demand attention from a shared resource or different resources
Lecture 10:
When Focussing Attention, What is Attentional Focus?
The directing of attention to specific aspects of our performance or performance environment
Lecture 10:
What are 3 key ways of focussing attention?
1.) Width of Focus - broad or narrow
2.) Direction of Focus - external or internal
3.) Attention Switching - changing of attentional focus
Lecture 10:
What is Automaticity?
The performance of a skill with little to no demand on attention capacity
- relates to evaluation of task demands
- different brain areas are active when tasks are automatized
Lecture 10:
What is Visual Selective Attention?
Refers to the detection & selection of performance-related information from the environment
- visual search located relevant information int eh environment to enable a person to determine how to prepare & perform a skill in a specific situation
Lecture 10:
How do eye-movements aid in visual selective attention?
Eyes track the location of central vision while observing a scene
Lecture 10:
When discussing how eye-movements aid in visual selective attention, what is “Point of Gaze”?
What a person is visually attending to is inferred from the “point of gaze” (locus of central vision)
Lecture 10:
What is the relationship between eye movements & visual attention?
Visual attention can be directed to an environmental feature without looking at it directly
Lecture 10:
How are Visual Cues Selected?
- what is the Feature Integration Theory?
The performer looks for specific cues in the environment that enable them to achieve a specific action goal
- Feature Integration Theory = initial visual search is based on specific features (eg; colour & shape) & selection of features occurs when a person focuses the attentional spotlight on master map of all features
Lecture 10:
When discussing visual search, what 3 aspects of the action control process does it influence?
1.) Action Selection
2.) Constraining of the Selected Action
3.) Timing of Action Initiation
**all 3 preparation processes influenced by visual search in both open & closed motor skills
Lecture 10:
What is the “Quiet Eye”?
The amount of time devoted to the final Fai action just before movement initiation
- directed to a critical location or object in performance
- stable fixation of performers gaze
- onset occurs just before the first movement
- duration of quiet eye is longer for elite performers
Lecture 11:
Define Memory
Memory is the capacity that permits organisms to benefit from past experiences
Lecture 11:
What are the 2 Functional Systems that memory structure is comprised of?
1.) Working Memory
2.) Long-Term Memory
Lecture 11:
What are the 3 Main Functions of Memory?
1.) Storage of Information
2.) Retrieval of Information
3.) System-Specific Functions
Lecture 11:
What is the 2-Component Memory Model?
Suggests that working memory & long-term memory are inter-related
Lecture 11:
Based on the 2-Component Memory Model, what are the 3 Subsystems of each functional system of memory?
Working Memory
1.) Phonological loop
2.) Visuospatial Sketchpad
3.) Central Executive
Long-Term Memory
1.) Procedural Memory
2.) Semantic Memory
3.) Episodic Memory
Lecture 11:
What is Working Memory?
Associated with sensory, perceptual, attentional, & short-term memory processes
- the temporary use & storage of information
Lecture 11:
What is the main function of the Working Memory?
Enables people to respond according to the demands of a “right now” situation
- used for critical decision making, problem solving, movement production, & evaluation
- interacts with long-term memory
- interactive workspace
Lecture 11:
How long does Working Memory last & what is it’s capacity?
Duration = 20-30 seconds before losing parts of information
Capacity = stores about 7 items, +/- 2 items
- people can increase capacity of an item in their memory
Lecture 11:
How do you process Activities?
Information active in working memory is processed in a way that allows a person to achieve the goal at hand
- involves memory of skill instructions to help when using experience as a reference to help future performance
Lecture 11:
What is Long-Term Memory?
Permanent storage of information that allows people to have information about specific past events & general knowledge
Lecture 11:
What is the Duration & Capacity of Long-Term Memory?
- Duration = information resides in a relatively permanent state
- Capacity = relatively unlimited capacity for information
Lecture 11:
What are the 3 Types of Memory Systems in Long-Term Memory?
- define each
1.) Procedural - allow us to know “how to do” something rather than allowing us to know “what to do”
2.) Semantic - knowledge about world based on experiences
3.) Episodic - knowledge about personally experienced events & their temporal associations “mental time travel”
Lecture 11:
Declarative Knowledge vs Procedural Knowledge
Declarative = knowledge about what to do in a situation that can be verbalized
Procedural = knowledge enabling skill performance & typically cannot be verbalized
Lecture 11:
Define Encoding (a remembering & forgetting term)
Encoding is a memory process of transforming to-be- remembered information into a form that is stored in memory
Lecture 11:
Define Storage (a remembering & forgetting term)
Placing information in Long-Term memory
Lecture 11:
Define Rehersal (a remembering & forgetting term)
Process that transfers information from working memory to long-term memory
Lecture 11:
Define Retrieval (a remembering & forgetting term)
Process of searching through long-term memory for information needed for present use
Lecture 11:
What are 2 types of Explicit Memory Tests?
- benefit of these tests
1.) Recall Tests
2.) Recognition Tests
Benefit = each test provides different information about what has been remembered or forgotten
Lecture 11:
What are Implicit Memory tests?
Tests that ask someone to verbally describe how to perform a skill & then having them perform it
Lecture 11:
What are 3 Key Causes of Forgetting?
1.) Trace Decay
2.) Proactive Interference
3.) Retroactive Interference
Lecture 11:
What are 2 groups of movement characteristics related to Memory performance?
1.) Location & Distance Characteristics
2.) Meaningfulness of the Movement
Lecture 11:
What are a few Location & Distance Characteristics related to movement & memory performance?
- movement endpoint is remembered better than movement distance
- arm end-location within persons own body space is remembered more than outside body surface
- implications for teaching motor skills = teachers can emphasize limb positions for successful performance
Lecture 11:
How does Meaningfulness of the Movement relate to movement & memory performance?
Movement becomes meaningful if it can be related to something someone knows (eg; move hands to the 2 o’clock position)
Lecture 11:
What are a few strategies used to help Enhance Memory Performance?
1.) Increase movement’s meaningfulness - use visual metaphoric imagery & verbal labels
2.) Increase Intention to Remember - intentional & incidental memory
3.) Subjective Organization - organize routines into units/groups of movements
Lecture 11:
What is the Encoding Specificity Principle?
Refers to the close relationship between memory encoding & retrieval memory processes
- the more the test resembles the practice, the better the retention performance is
Lecture 12:
Define Performance & provide a few details about it
observable behaviour executed at a specific time & location
- temporary & may not result from practice (could be based on better equipment, more energy, etc)
- may be influenced by performance variable
Lecture 12:
Define Learning & provide a few details about it
A change in the capability to perform a skill
- relatively permanent & due to practice
- not influenced by performance variables
