Psychological refractory period. They administered the experiment again with either a less complicated first task or less complicated second task. AQA A level PE Hicks Law - Psychological Refractory Period - Information processing (no rating) 0 customer reviews. 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. The delay is caused by an increase in the time of information processing, when the initial stimulus is followed closely by a second. , time period of slowed response to a second stimulus because a first is still being processed, Experimental and Clinical Psychopharmacology, "Brain Mechanisms of Serial and Parallel Processing during Dual-Task Performance", Demonstration of a PRP paradigm using the PsyToolkit website, https://en.wikipedia.org/w/index.php?title=Psychological_refractory_period&oldid=962438588, Creative Commons Attribution-ShareAlike License, This page was last edited on 14 June 2020, at 02:18. Then use a diagram or explanation or practical example to illustrate this term/word in the Neurons that take in information send this information to specific neural networks in different locations. The PRP can be used to investigate many areas of research that study processes which require divided attention, such as reading aloud, language, or driving and talking on the phone. These differences could be due to the fact that older adults have a reduced ability to bypass the central bottleneck, through task automatization. Award up to 2 marks for application of PRP. [4 marks] A. The car in front of them would occasionally brake, causing the participant to brake. Created by: daniellecampbell; Created on: 14-03-16 14:37; Fullscreen. Write this out in your own words. Factors affecting reaction time, Hick's law, psychological refractory period, single channel hypothesis. It is that delay, with attending and then wiping out the first decision, and then attending to the second decision, that is called the Psychological Refractory Period (PRP). Refractory period in biology [edit | edit source] Main article: Refractory period (physiology) Biologically, a refractory period is the amount of time it takes for an excitable membrane to be stimulated and then be ready for stimulus again.. Action potentials in Neurons [edit | edit source]. Anticipation. These concepts vary in specific mechanisms, however, they both propose an overall limit to the amount of mental activity in which we can engage in. Meaning of psychological refractory period. Initiates movement, comes before the action. Anticipation – temporal/spatial ... in PE. Definition of psychological refractory period in the Definitions.net dictionary. PRP effects related to personality, age, and level of alcohol or caffeine intake have also been investigated. Created: Dec 9, 2018.  The processing of the second stimulus is postponed which slows down reaction time. Linked to reaction time. , The PRP affects not only simple dual tasks such as the way we read or speak, it also can affect more complicated tasks such as driving. Information processing theory models explain how the brain processes information when learning and performing sports skills.  However, studies have aimed to determine if dual-task practice can help remove elderly disadvantages. MARK SCHEME – A-LEVEL PHYSICAL EDUCATION – PHED1 – JUNE 2014 7 of 17 3 (b) When playing tennis, the ball occasionally hits the top of the net during a rally and the receiver has to adjust their response. Therefore, older adults either have the ability to use automatic-memory retrieval and bypass the bottleneck and it is just less likely to be used, or they have actual lost the ability entirely. 2.  Participants in this study performed a PRP task that measured dual-task interference. What does psychological refractory period mean? AQA A level PE Hicks Law - Psychological Refractory Period - Information processing. The reaction time is slowed down because of the first stimulus having to … We are only able to process one piece of information at a time. Alcohol impairs both speed and accuracy performance in PRP tasks, and while caffeine can reduce speed impairments, accuracy remains poor. This causes a delay before the final response can be made. Author: WeaverL  The PRP is likely caused by a combination of two approaches; the bottleneck approach and the capacity approach. Motor programmes and sub routines; Factors affecting the efficiency of the components of the information processing system and strategies for improvement. Psychological refractory period B. PRP is a product of the psychological refractory period paradigm, a paradigm in which two different stimuli are presented in rapid succession, each requiring a fast response. During the psychological refractory period, a network of brain regions in both the back and front of the brain are activated.  There is also a task 2 which requires participants to push the keyboard-letter 'v' with the left index finger when the digit displayed was a '3' and to push the letter 'c' with the left middle finger if the digit displayed was a '4'. This delay in response time when one is required to divide attention can exhibit a negative effect that is evident in many fields of study. PRP continued Psychological Refractory Period or PRP is the delay caused because of an increase in processing time when the first stimulus is closely followed by a second stimulus e.g. This covers content within the Information processing unit and includes all necessary content for the AQA specification.  Therefore, if two tasks are in separate modalities they should not interfere with each other. Factors affecting reaction time, Hick's law, psychological refractory period, single channel hypothesis. , PRP studies have challenged the notion that central attention does not play a role in reading aloud. Anticipation and Psychological Refractory Period. An example of a PRP paradigm might be that there is a task 1 which requires participants to push the keyboard-letter ‘n’ … Profile Quizzes Subscribed Subscribe? A LEVEL PE Below are a number of key terms/words that are essential for the first two modules that will be started in September. The delay in response to the second of two closely spaced stimuli. Young and old participants were assigned to practice 7 blocks of PRP paradigm design. Limited mental resources must be shared when doing two tasks at once. We are only able to process one piece of information at a time. Filtering relevant information from irrelevant information. The psychological refractory period explains the increase in reaction time. This causes a delay before the final response can be made. It is that delay, with attending and then wiping out the first decision, and then attending to the second decision, that is called the Psychological Refractory Period (PRP). Areas of study include Whiting’s model of information processing, Hicks Law as well as factors affecting reaction time, single channel hypothesis and Psychological refractory period. 6 terms. The task is: 1. Thie AQA Alevel PE resource focuses on the Hicks Law principle and it’s application to real life sporting examples. The Psychological Refractory Period (PRP) effect is a delay in responding that is assumed to be caused by a bottleneck that prevents preparation of a second action until preparation of the previous action has been completed.  However, this finding was further tested with older adults. Powered by Create your own …  In the PRP paradigm they were first asked to read the words aloud quickly, and then asked to respond to a tone by responding to the letter string (counterbalance order of words). The wikipedia link does a good job explaining the phenomenon. Thie AQA Alevel PE resource focuses on the Hicks Law principle and itâs application to real life sporting examples.
