What’s the explanation for this according to Eysenck’s theory? <LI>Draw and describe the Inverted U Theory. Explain at least two considerations in the application of the theory. <LI>What is perceptual narrowing and when is it likely to occur? <LI>Which system has limited capacity, the Pyramidal or Extra-pyramidal? </UL> <BR><IMG SRC="swash5.gif"> <P><P> <Strong>Here’s some more questions used previous years</strong> <P> <UL> <LI>Labeling motor neuron consists of several parts, these are the ones I would label: <UL> <LI>dendrites, axon <LI>axon, soma, nodes of Ranvier, dendrites <LI>post synapse, dendrites, soma, axon hillock, axon, nodes of Ranvier, pre synapse <LI>dendrites, synapse, soma, axon, sodium, schwann cells, vesicles, </UL><LI>The amount of stimulation to ‘fire’ a resting motor neuron is <UL><LI>a) ab - 55 mvl <LI>+15 mvl <LI>- 15 mvl <LI>+ 30 mv </UL> <LI>The resting motor neuron is -70 mvl - True or False <LI>The resting potential of a motor neuron is maintained by <UL><LI> Potassium <LI>Sodium Pump <LI>Chloride Pump <LI>Anions </UL> <LI>The insulation of the axon is called: <UL><LI>a) Schann <LI>b) Myelin Sheath <LI>c) Schwann Sheath <LI>d) Sodium Sheath </UL> <LI>At rest the polarity of the axon is: <UL><LI>predominately positive inside and negative outside <LI>predominately negative inside and positive outside <LI>neutral inside and outside </UL> <LI>The nerve impulse (signal) travels down the axon by a method known as: <UL><LI>Chemical conductancce <LI>Myelin Conductance <LI>Saltatory Conductance <LI>Vesicles </UL> <LI>Jumping down the axon, the impulse goes from Node Of Ranvier to Node of Ranvier True or False <LI>The benefits of having the impulse travel down the axon the way it does are: <UL><LI>it cannot be seen or touched <LI>quicker and quieter <LI>quicker and uses less energy </UL> <LI>Once the impulse (signal) reaches the end of the axon, it: <UL><LI> releases more vesicles which ‘open’ the + or - gates on the opposite dendrite <LI>it jumps across the synapse to the next dendrite <LI>stops until another impulse arrives </UL> <LI>Signals can be either inhibit (- effect) or stimulate (+ effect). True or False <LI>The main chemicals involved in nerve transmission are <UL><LI>sodium, & chloride (Na+, Cl-) <LI>sodium, chloride, & potassium (Na+, Cl-, K+) <LI>sodium, potassium, chloride, organic Anion (Na+, K+, Cl-, A-) </UL> <LI>Recurrent inhibition is where active neurons inhibit adjacent neurons - True or False <LI>The space between each motor neuron is called: <UL><LI>dendrites <LI>pre synapse <LI>synapse <LI>schwann cells </UL> <LI> The area of the brain most directly under our control covering many parts of the body is <UL><LI>posterior lobe <LI>basal ganglia <LI>brain stem <LI>motor cortex </UL> <LI> The pre motor cortex is responsible for <UL><LI>proximal muscles, and orienting and readying the body for movements <LI>sending motor plans to the motor cortex <LI>pulling plans together for the motor cortex </UL> <LI>The pathway from the brain to muscles of the body which is under our control is called the Extra-pyramidal system True or False <LI> The size principle in muscles means that large motor neurons are recruited first True or False <LI>The development of skilled movement would seem to follow the following sequence <UL><LI>put together smaller units <LI>reflex, reflex control, combining engrams, practice til auto matic, motor plans with adjustable parameters <LI>combining reflexes and motor plans, practice ‘til perfect. </UL> <LI>In a motor plan, there are parameters which allow for adjustment of the movement, rather than having to have a new plan for each movement such as dart throwing and football throwing. True or False <LI>If someone has a problem in a movement pattern, the coach/ teacher must identify which engram to change, then work on that before rebuilding the whole skill. True or False <LI>The Basal Ganglia is responsible for: <UL><LI>muscles in different parts of the body <LI>retrieving sending motor plans to motor cortex, such as walking <LI>gathering different sensory input and coordinating movement </UL> <LI> Anxiety can be said to consist of two types State and Trait - True or False <LI>The Inverted U Theory states: <UL><LI>increased stress/anxiety (arousal) hinders performance <LI>increased stress/anxiety helps performance up to an optimal level <LI>increased stress/anxiety helps performance up to an optimal level, beyond that it hinders performance </UL> <LI>Situational anxiety is called trait - True or False <LI> Signal Detection Theory is concerns the question, “Was it a signal or not?” True or False <LI>A coach/ teacher can help a performer under the Signal Detection Theory Model by: <UL><LI>moving the cut-off point <LI>moving the cut-off point, and reducing the noise <LI>drawing attention to the noise </UL> <LI> In Signal Detection Theory there are three major parameters to consider <UL><LI>the performer, the environment, and the signal <LI>noise in system, noise plus signal, cut-off <LI>noise in system, the signal, and the performer </UL> <LI>In Eysenck’s Personality Theory there is a physiological explanation to personlity True or False <LI>In Eysenck’s theory, there are two personality types on the extremes, and everything in between. These are Introvert and Endomorph - True Or False <LI>In Eysenck’s Theory, the Introvert is a stimulation seeker <LI>In Eysenck’s Theory, different sports or different positions within a sport would suit one type better than the other. True or False <LI> In Eysenck’s Theory, it means that the coach should be careful when psyching up the introvert before a game.
