Motor Learning Unit 3

What is attention?

conscious awareness of a task that puts cognitive effort (energy) towards a performance

What is filter or bottle-neck theory?

The serial order of processing stimuli in motor response processing. This theory uses selective attention to filter “unimportant” noise out to avoid over-processing. It works under the assumption that there is a limited capacity to store information and does not factor in multi-tasking

What is the limitation of filter theory?

serial processing

What is selection attention a component of?

Filter theory—selective attention refers to the process of filtering out excess information that does not need processed

What is the serial order of filter theory?

Environmental information/stimuli—> the filter (info, detect, identify)—> response selection—> preparation of response—>response

When can multitasking occur according to central resource theory and multiple resource theory?

If the resources are available

What is the central resource capacity theory

There is one central source, the central reserve, of attention resources where all activities requiring attention compete (CNS). All small tasks must fit into the overall attention capacity

What is multiple resource theory?

As the stress of one stimuli increases, the attention to the other must decrease

What’s the difference between central resource capacity theory and multiple resource theory?

In central resource theory, all stimuli or tasks requiring attention must fit in our attention capacity, but in multiple resource theory all stimuli can fit but we can only give certain levels of energy or attention ratios so to speak can fit (something has to decrease for something else to increase)

What is the alternative theory of multiple resource theory?

Proposes we have several sources for attention but each source has a limited capacity of resources. Each of these sources has a pool of resources specific to a component of performing the skill

What are the three components of alternative theory?

1) Input/output modalities (visual, limbs)

2) Information processing (encoding, retrieval)

3) Type of memory code (spatial, verbal)

What does success of a task depend on in multiple resource theory?

whether the tasks demand attention from common or multiple resources

What does multiple resource theory describe?

Multi-tasking, so competition for attentional resources is occurring.

How does having a shared common resource vs multiple resource effect task success?

Tasks with shared common resources will compete for resources resulting in a decrease in attention to each vs. multiple resources result in less competition as each task is spread across a different area of focus increasing the chance for a successful performance

What is dual-task procedure?

determines the attention demands and characteristics of the simultaneous performance of two different tasks

What is the difference between the primary and secondary task?

The primary task is the task of interest and the secondary task is the basis to make inferences about the attention demands of the primary task. Ex: if the primary task performance is compromised when the secondary task is performed, inferences can be made about attention demands

What is a continuous secondary task?

Attention capacity is required for the whole performance, the primary and secondary tasks are performed separate and simultaneously

What is a Secondary Task Probe?

-attention demands will require prep

- specific components or times during performance

-primary and secondary tasks are performed separate and simultaneously

-the secondary task is discrete and performed intermittently before/during task 1 (task 2 probes task 1)

What is the difference between attention demands and attentional focus?

Demands focus on the performance of the task while focus directs attention to the action preparation and the performance environment

How can attentional focus be broken down?

the width of focus and direction of foucs

What’s the difference between the width of focus and the direction?

the width describes the environmental context whereas the direction describes the external or internal attention focus

When learning new skills what is the direction of focus compared to practiced skills?

New skills have an internal focus because the person is focusing on themselves and the movement whereas practiced skills have an external focus because the skill itself has become automatic

What is the width and direction of attention when walking down a busy street?

Width: broad

Direction: external

What is the width and direction of attention when a SKILLED player is catching a baseball

Width: narrow

Direction: external

What is attention switching?

changing attentional focus from internal and external in a situation that requires rapid decision making (open, externally paced skills like football QB)

How does a football quarterback’s attention switch during a game?

he switches from internal direction when deciding to make the throw or run to external direction as he is watching for receivers and defenders in the environment around him

When learning a new skill, direction is focused ______

internally

With a well practiced or learned skill, direction is focused ______

externally

When attention is focused internally, performance _____

decreases

When attention is focused externally, performance ____

increases

According to the action effect hypothesis, actions are best planned and controlled by their intended ____ rather than their

outcomes; movements

T/F The Action Effect Hypothesis applies to both new and learned skills

False: it only applies to learned skills because when the performer is practicing new skills they should be focusing their attention inwards to learn the movements

Why does internal focus limit your performance?

When the attention is directed inwards, the motor system is constrained while it focuses on improving consistency and naturality of posture and positioning. This conscious control takes up energy and slows the performer down and decreases reaction time

What is the constrained action hypothesis?

States that the motor control system is constrained when the performer tries to consciously control their movements, creating interference in the motor system

What’s the difference between the action effect hypothesis and the constrained action hypothesis?

the action effect hypothesis describes well-learned actions are better performed when they are planned based on their intended outcomes rather than movements whereas the constrained action hypothesis applies to all movements because it describes the constrain internal focus places on the motor system

When focus is external, the motor program runs on _______

autopilot

What is automaticity?

the performance of a skill without requiring attentional resources

How does automaticity benefit skill performance?

The brain has more attentional resources to direct towards external focus in the environment like time-to-contact cues, retrieval of info from memory, and selection of action/movement characteristics

How do fMRI studies show automaticity in skill performance?

Learned skills have condensed, focused regions of the fMRI light up whereas new skills have large regions of the brain activated

How is automaticity achieved?

practice and training (10,000 hours to become an expert)

What is visual selective attention?

The use of vision to identify relevant environmental information to prepare and execute actions while ignoring the irrelevant ones

Active vs passive visual cues

active: actively looking/searching for

passive: responding to stimuli

Does eye movement and point of gaze indicate where visual selective attention is directed?

Not necessarily—> people use their peripheral vison to pick up signals

What do we search for when selecting visual cues?

regulatory conditions

regulatory vs nonregulatory conditions

regulatory will help you achieve the action or goal, nonregulatory is the extra information that needs filtered out

What is feature integration theory?

describes how visual cues are selected: we initially search according to specific features and group stimuli together before directing attention on the environment to narrow in our focus

What is visual mapping?

locating objects in the environment around you and determining which ones pop out (more features will take longer to map, more practice allows this skill to become more automatic)

What is a movement filter?

filters focus to the movement or moving objects only (ie: focusing on the opponent)

How are visual cues selected (advanced performer)?

they will select the minimal amount of essential information—skilled players pick out this info more quickly and accurately than novices which allows them to anticipate their opponents actions for quicker RT/MT

What are examples of minimal essential information for successful performance?

time to contact, movement of opposing players, etc

Visual search picks up cues that influences which 3 aspects of action preparation?

1) action selection —recall schema (check positioning)

2) constraining of the selected action to determine specific movement features for performing the action (this controls the degrees of freedom)

3) timing of the action - perception action coupling

By influencing the three aspects of action preparation, the visual system enables a person to _____

prepare and initiate movements of an action that conform to the specific requirements of the performance context

What does action selection/recall schema help with in visual cue search?

postural adjustments and positioning

What does constraining of the selected action help with in visual cue search?

controlling the degrees of freedom to allow the performer to become automatic and not internally constrained

When making a free throw, where do experts look?

directly at the backboard or hoop for a longer period than near experts (key during the final eye movement fixation prior to ball release)

What is low handicap vs high handicap in putting?

low: more skilled

high: less skilled

In the putting prep phase, did low or high handicap golfers take more time?

low handicap took less prep time

Where did low handicap golfers fix their gaze during prep?

Low handicap fix their eye movement on the ball versus the putter like high handicap putters

Where does fixating gaze in putting have more success?

the ball (rather than the putter)

What are strategies for improving visual search techniques?

experience and practice (often from implicit learning of relevant visual cues). Instruction will also help facilitate a visual search from novice to skilled

Implicit vs explicit visual search

implicit search is involuntary whereas explicit is being directly told

What is a key difference in the visual search between experts and novice players?
