Stable characteristics or traits.

Behaviour is a function of personality and the environment.

Innate characteristics dictate your personality producing consistent behaviours. (nature)

90

91
Q

Catastrophe theory

A

As arousal increases so does performance, up to a certain point at which a dramatic decrease in performance occurs.

92
Q

Drive theory

A

As arousal increases so does performance.

92
Q

Aggression

A

An emotional response to an individual perceived as a frustrating rival.

93
Q

Cognitive anxiety

A

Psychological reactions, like stress

93
Q

Inverted U theory

A

As arousal increases so does performance up to the optimal point, after so, performance decreases gradually.
Optimal point changes with sport.

93
Q

Competitive trait anxiety

A

An enduring personality trait, giving a tendency to view all competitive situations as threatening.

93
Q

Optimal performance zone (arousal) (peak flow)

A

High focus on task
Movement feels effortless
Clear goals
High levels of self-efficacy
Sub-conscious feelings of control, like being on autopilot.

93
Q

Competitive state anxiety

A

Anxiety felt in a particular competitive situation

93
Q

Somatic anxiety

A

Physiological reactions to stress, like sweating, butterflys, shaking.

93
Q

Aggressive cue hypothesis

A

Frustration will only lead to aggression when learned triggers are present.

94
Q

Assertive behaviour

A

Forceful behaviour which occurs within the rules of the sport.

95
Q

Frustration-aggression hypothesis

A

When a performer is blocked from their goal they become frustrated. Frustration leads to aggression.
Aggressive act will have a cathartic effect on the performer.

96
Q

Instinct theory (of aggression)

A

Aggression is an innate trait.

97
Q

Social learning theory (of aggression)

A

Aggression is a learned response, developed from copying others.

98
Q

Achievement goal theory

A

Motivation is based on type of goal set.
Performance or outcome goals.

99
Q

Incentive value

A

The pride experienced by the individual after success has been achieved.
The harder the task, the greater the incentive value.

100
Q

Characteristics of NACH

A

Seeking out challenging situations
Taking risks
Displaying high levels of task persistence
Valuing feedback
Developing a self-serving bias.

101
Q

Characteristics of NAF

A

Low task persistence
Dislike of feedback or evaluation
Selecting the easy option when choice is available

102
Q

Probability of success

A

The extent to which the performer is likely to complete the task correctly.

103
Q

What is an Ischaemic stroke?

A

Occurs when a blood clot stops the supply of blood reaching the brain.
The most common type of stroke.

104
Q

What is a Haemorrhagic stroke?

A

A haemorrhagic stroke is a result of a weakened blood vessel to the brain bursting.

105
Q

What is beta oxidation?

A

When stored fat is broken down into fatty acids, before being converted into acetyl-coenzme A

106
Q

Simple definition of the krebs/citric acid cycle?

A

Oxidation of acetyl-coenzyme A.
This results in 2 ATP and produces carbon dioxide as a waste product.

107
Q

Simple definition of the Electron transport chain?

A

The transfer of electrons down a carrier chain, hydrogen is oxidised.
Resynthesis 34 ATP and produces water as a waste product

108
Q

What is the cognitive stage of learning?

A

This is the first stage where learning is very much trial and
error. The performer lacks a clear mental image of what the skill should look like so learns
through observing others to develop understanding of the relationships between subroutines. Large errors will often be made.

109
Q

What is the Associative stage of learning?

A

Associative learners are in the practice stage. They will have
developed a mental image of the skill but will still be reliant on some external feedback.
They are starting to develop intrinsic feedback by comparing their performance to others.
Though errors are still evident they are smaller and there are fewer of them.

110
Q

What is the Autonomous stage of learning?

A

Performance of skills can be completed with little thought
allowing the performer to concentrate on other aspects such as tactics and strategies.
Intrinsic feedback is highly developed so the performer can self-correct. They’re very few, if
any smaller errors in skill execution.
