According to what is known as “
The Yerkes-Dodson law
,” performance increases with physiological or mental arousal (stress) but only up to a point. When the level of stress becomes too high, performance decreases.
What is inverted-U theory?
The Inverted-U Theory
illustrates the relationship between pressure and performance
. Also known as the Yerkes-Dodson Law, it explains how to find the optimum level of positive pressure at which people perform at their best. Too much or too little pressure can lead to decreased performance.
What is the inverted-U theory of stress?
The Yerkes-Dodson law is a model of the relationship between stress and task performance. It
proposes that you reach your peak level of performance with an intermediate level of stress, or arousal
. Too little or too much arousal results in poorer performance. This is also known as the inverted-U model of arousal.
What is catastrophe theory psychology?
CATASTROPHE THEORY. Physiological arousal is
related to performance
in an inverted ‘U’ fashion when the athlete is not worried or has low cognitive anxiety state anxiety. If cognitive anxiety is high, the increases in arousal pass a point of optimal arousal and a rapid decline in performance occurs (the catastrophe).
What is multidimensional anxiety theory?
Theory that predicts that an increase in cognitive state anxiety (worry)
has a negative effect on performance
. The theory is based on the premise that state anxiety is multidimensional with its two components (cognitive anxiety and somatic anxiety) influencing performance differently.
How does the inverted U theory work?
The ‘inverted U’ theory proposes that
sporting performance improves as arousal levels increase but that there is a threshold point
. Any increase in arousal beyond the threshold point will worsen performance. At low arousal levels, performance quality is low. … At high arousal levels, performance quality deteriorates.
What is arousal state?
Affect arousal describes the
state of feeling awake, activated, and highly reactive to stimuli
. There are both psychological and physiological components to the state of arousal. Psychologically, the state of arousal is associated with the subjective experience of feelings including high energy and tension.
When is it good to have high physiological arousal?
Higher arousal levels can sometimes help us perform better, but it can also impair performance if arousal levels are too high. This concept is commonly referred to as the Yerkes-Dodson Law. The law states that increased levels of arousal will improve performance, but only up until the optimum arousal level
is reached
.
What is the optimal level of stress?
Optimal Levels of Arousal (i.e. Stress)
Research shows that
moderate arousal
is generally best; when arousal (stress) is very high or very low, performance tends to suffer.
What is inverted U shaped curve?
INTRODUCTION. The so called “inverted U-shaped dose-effect curve” (IUSDEC) is
a nonlinear relationship
which has been frequently reported when studying the negative or positive actions of pharmacological and non-pharmacological treatments on cognitive functions and memory.
What are the 4 theories of arousal?
- Drive Theory.
- Inverted U hypothesis.
- Catastrophe Theory.
- Zone of Optimal Functioning (ZOF) Theory.
What is catastrophe theory anxiety?
Catastrophe theory proposes that
cognitive anxiety acts as the splitting factor that determines whether the effect of physiological arousal will be small and smooth, large and catastrophic or somewhere between these two extremes
(Fazey & Hardy, 1988).
What is stress arousal?
Stress is an emotion that can have a positive or negative outcome. It is
caused by a stimulus
, which results in arousal and possible action. Arousal is another emotion that involves activation and excitation. At high levels of stress and arousal, actions can be inhibited.
What is the definition cognitive anxiety?
The authors broadly defined cognitive anxiety as
“negative expectations, worries, and concerns about oneself, the situation at hand, and potential consequences”
and somatic anxiety as “the perception of one’s physiological arousal.” A similar two-factor structure was replicated in a number of studies, with the somatic …
What does anxiety stand for?
Anxiety
is a normal emotion. It’s your brain’s way of reacting to stress and alerting you of potential danger ahead. Everyone feels anxious now and then. For example, you may worry when faced with a problem at work, before taking a test, or before making an important decision. Occasional anxiety is OK.
What is a multidimensional person?
Describing something as multidimensional implies
that it’s complex
. You could talk about a multidimensional book filled with intricate themes, characters, plots, and symbols; or you could even call a person multidimensional if she had a particularly complicated personality.
