What is shown to help treat schizophrenia?
Exercise
* Have better inhibitory control
* Individual has better emotional control and inhibitory control
How are motor skills classified in terms of taxonomies?
- Task Organization
- Motor and Cognitive Elements
- Level of Environmental Predictability
List:
Types of task organization
- Discrete skill
- Serial skill
- Continuous skill
Define:
Discrete skill
A skill organized such that the action is usually brief and has a well-defined beginning and end (e.x. hitting a golf ball)
Define:
Serial skill
A type of skill characterized by serial discrete actions connected in a sequence
True or False:
Serial skills are brief
Not quite. Serial skills are characterized by serial discrete actions, where often the order of the action is critical to performance success (e.x. driving manual car, make a cup of coffee)
Define:
Continuous skill
A skill that unfolds without a recognizable beginning or end, in an ongoing and often repetitive fashion (e.x. swimming)
True or False:
No task is continuous
Technically true, thus tasks have to be described on a spectrum
List:
Types of motor and cognitive elements
- Motor skill
- Cognitive skill
- Motor/Cognitive skill
Define:
Motor skill
Primary determinant of movement success is the quality of the movement (e.x. buttoning a shirt), primarily motor in nature
Define:
Cognitive skill
Primary determinant of success is the quality of the performer’s decision making (e.x. chess)
What activities require motor and cognitive skills?
Team sports (skills + strategy/decision making with team)
List:
Levels of environmental predictability
- Closed skill
- Open skill
- Semi-predictable skill
Define:
Closed skill
Skill performed in an environment that is predictable or stationary and that allows individuals to plan their movements in advance (e.x. bowling)
True or False:
In a closed skill, the environment is dynamic
False, the environment is predictable and stable
Define:
Open skill
Skill performed in an unpredictable or in motion environment, requiring individuals to adopt their movement in response to the dynamic properties of their environment (e.x. team sports)
What skills are semi-predictable?
Driving a car (on open road vs. congested traffic)
If a patient has a pre-motor lesion, what skills do they have to be kept away from?
Open skills
Define:
Reaction time (RT)
The interval between the onset of a signal (stimulus) and the initiation of a response
What type of reaction time tasks are there?
- Simple reaction time (SRT)
- Choice reaction time (CRT)
- Discriminant reaction time (DRT)
What is the discriminant reaction time also known as?
Go/No Go Task
In reaction time tasks:
What is the foreperiod?
The time between warning signal and go signal, randomized to prevent anticipation
In reaction time tasks:
What is the reaction time?
The time between go signal and when the movement starts
True or False:
SRT task does not address executive function
True
