What does the skill acquisition module cover?

It covers four areas: classifying motor skills using continua (open and closed, gross and fine, simple and complex); the information-processing model of input, decision making, output and feedback, and the factors affecting reaction time; the cognitive, associative and autonomous stages of learning and the coaching suited to each; and the types of practice, guidance and feedback and how to select the right one for a skill and learner. The theme is how skills are learnt and improved.

What are the three stages of learning?

The cognitive stage is the beginner phase, where the learner works out what to do, makes many errors and needs lots of demonstration and positive feedback. The associative stage is the practice phase, where movements become smoother, errors reduce and the learner begins to use their own feel for the movement. The autonomous stage is the expert phase, where the skill is performed almost automatically with little conscious thought, freeing attention for tactics, and feedback becomes more detailed and technical.

What is the information-processing model?

The information-processing model describes how a performer turns information into action in four stages: input (taking in information from the senses, with selective attention filtering the important cues), decision making (choosing the right response using memory), output (sending the movement command to the muscles to act), and feedback (information about the result, used to adjust the next attempt). It explains how a player perceives a situation and produces a skilled response.

What factors affect reaction time in sport?

Reaction time is the time between a stimulus appearing and the start of a response. It is affected by the number of choices (more options slow the response, known as choice reaction time), the intensity and clarity of the stimulus, the performer's age, fitness and experience, anticipation of the cue, and arousal level. Sportspeople improve effective reaction time by anticipating cues and reducing the number of choices through practice.

What this module is about

Skill acquisition is the psychology of learning to move well, and the O-Level Exercise and Sports Science syllabus (SEAB 6081) asks you to classify skills, model how a performer processes information, track how learning progresses, and choose the practice and feedback that develop a skill fastest. It connects to sports psychology, since arousal affects both reaction time and learning. This overview links the four dot points; work each in full for the worked answers and practice questions.

Classifying skills

Start by describing the skill. The classification of skills page places motor skills on continua, open versus closed (affected by the environment or not), gross versus fine (large versus small muscle groups), and simple versus complex (few versus many decisions), and shows how to justify the placement of a sporting skill on each.

Information processing and reaction time

The information processing page sets out the input-decision-output-feedback model, the role of memory and selective attention, and the factors affecting reaction time, including a ruler-drop calculation that estimates reaction time from a fall distance.

The stages of learning

The stages of learning page describes the cognitive (beginner), associative (practice) and autonomous (expert) stages, their features, and how feedback and coaching should change as a learner progresses.

Practice, guidance and feedback

The types of practice and feedback page covers massed and distributed, fixed and variable, and whole and part practice; the types of guidance (visual, verbal, manual and mechanical); and the types of feedback (intrinsic and extrinsic, knowledge of results and performance), and how to choose the right approach for a given skill and learner.

Estimating reaction time from a ruler-drop test

A question gives the distance a ruler falls before being caught and asks for the reaction time. Take a learner who catches the ruler after it has fallen 0.20 m, using gravity $g = 9.8$ m per second squared.

Step 1: Recall the falling-object relationship

The distance fallen relates to time by:

d = \frac{1}{2} g t^2

Step 2: Rearrange to make time the subject

t = \sqrt{\frac{2d}{g}}

Step 3: Substitute the values

t = \sqrt{\frac{2 \times 0.20}{9.8}} = \sqrt{\frac{0.40}{9.8}} = \sqrt{0.0408}

Step 4: Evaluate the reaction time

t \approx 0.20 \text{ seconds}

So the learner's reaction time is about 0.20 seconds. A shorter fall distance means a faster reaction time, which is why catching the ruler higher up shows quicker reactions. Showing the formula, the rearrangement and the units secures every mark.

Solutions

Q1: A free throw is a closed skill. It is performed in a stable, predictable environment with no opponent interference, the player decides when to start, and the movement is the same each time, all features of a closed skill.
Q2: Input, decision making, output, and feedback.
Q3: In the cognitive stage the learner is a beginner working out what to do, so movements are jerky and errors are frequent. The coaching should use plenty of demonstration and simple instructions, and feedback should be positive and focus on the main points to build confidence and a basic correct model.
Q4: Intrinsic feedback comes from within the performer through their own senses and feel for the movement; extrinsic feedback comes from an outside source such as a coach or a video. Both are used to improve performance.
Q5: An open skill such as dribbling is performed in a changing environment with opponents, so the player must adapt the movement to many situations. Variable practice rehearses the skill in many different conditions, building the ability to adjust, which fixed (repetitive) practice would not develop.
