Q

What are continuous skills?

A

The end of the movement cycle is also the beginning of the next. The skill is usually repeated until a time or distance goal has been achieved. E.x swimming

Q

What are abilities?

A

Abilities are genetically predetermined characteristics

Abilities differ from skills as skills are learned whereas abilities are genetic characteristics.

Abilities use both perceptual motor skills and physical proficiency abilities

21
Q

Define abilities

A

Ability refers to a general trait or capacity of the individual that is related to the performance and performance potential of a variety of skills or tasks.

22
Q

Define the term technique

A

Technique in general terms is a “way of doing”. In the performance of a specific sports skill it is defined as the “way in which that sports skill is performed”.

23
Q

State the relationship between ability, skill and technique

A

Skill = ability + selection of an appropriate technique

24
Q

Discuss the differences between Skilled and Novice Performers

A

Skilled

Fluent Movements

Know what they want to achieve and how to achieve it

Efficient – Energy is not wasted

Consistent performers

Accurate in the application of skill

Novice

Often un-coordinated movements

Do not always know what they are trying to achieve

Inefficient movements – Lots of energy wasted

Inconsistent performers

Inaccurate

25
Describe a simple model of information processing
Information processing is the system by which we take information from our surrounding environment, use it to make a decision and then produce a response: input–decision-making– output.
26
Welford's Model of information processing
sense organs * perception * short-term memory * long-term memory * decision-making * effector control * feedback
27
What are the three sensory inputs?
- Exteroceptors - propioceptors - interoceptors
28
What do exteroceptors do?
provide information from outside of the body, about the external environment, like touch, pressure, temperature
29
What do proprioceptors do?
provide information about the position and posture of our body in space. They sense stimuli from the muscles, tendons and joints
30
What are interceptors?
provide information about the events in the viscera. E.g receptors sensing blood pressure, plasma osmolarity, blood glucose concentration
31
Explain the Signal Detection Process
Often referred to as the detection–comparison–recognition process (DCR). Limit to background noise, intensity of the stimulus, efficiency of the sense organs, early signal detection and improving signal detection.
32
What is the short term sensory store?
All incoming information held here for a brief time. Information is only retained and passed to the STM if it’s rehearsed (mentally processed)
33
What is short term memory?
Rehearsed info from the STSS is passed onto the STM 90% of the information lost within the first 10 seconds. STM has a limited capacity (7±2 pieces if info)
34
Long term memory
No capacity limitations It is where all the info that enters the STM and is rehearsed, is stored. Info from STM is stored as LTM or lost
35
Discuss the relationship between selective attention and memory
This theory states that all input enters the STM Selected stimuli are compared to the LTM in order to make a decision Past experience helps with signal attention
36
What are the different methods of memory improvement?
brevity clarity chunking organization association practice coding
37
Define the term response time
Response time = reaction time + movement time
38
Outline factors that effect response time
Response time is an ability, having individual and group variance (for example age, gender, physical fitness, fatigue, distraction, alcohol, personality type, and whether the stimulus is auditory or visual.
39
Evaluate the concept of psychological refractory period (PRP)
The term psychological refractory period (PRP) refers to the period of time during which the response to a second stimulus is significantly slowed because a first stimulus is still being processed
40
Describe a motor program
a set of movements stored as a whole in the memory regardless of whether feedback is used in their execution
41
42
What is open-loop perspective
Performance of a skill without feedback Very fast movements
43
What is closed-loop perspective?
Feedback is utilized to adjust the program Allows us to adjust movement during its execution
44
What is Adams' closed loop theory
Memory trace: responsible for selecting and initiating the movement (comparing to LTM) Perceptual trace: a reference model acquired through practice. It is used to adjust the movement. This is accomplished by comparing the incoming feedback to the perceptual trace Feedback is used to modify on-going action
45
Explain the differences in the performance of a dive start by a skilled swimmer and a novice swimmer
**Fluent movement** compared to the novice. Appears to be one fluid motion. The skilled diver is **accurate** compared to the novice. The skilled diver is **controlled,** ie body position is properly controlled and maintained. **Goal-directed**. The skilled swim diver is completing the dive to give him/her the most advantage for the swimming race. **Learned.** The skilled diver has been well-coached over a period of time. **Aesthetic.** The skilled diver's movement is pleasing to the eye.
46
What are the different feedbacks
Intrinsic Feedback Extrinsic Feedback Knowledge of Results Knowledge of Performance Positive feedback negative feedback
47
What is intrinsic feedback
Available to a player without outside help
48
What is extrinsic feedback?
Provided by someone or something else (coach, stopwatch)
49
What is the knowledge of results
Post-response information about the outcome of an action.
50
What is the knowledge of performance
Post-response information concerning the nature of the movement. The ‘feel’ of a movement
51
What is positive feedback
