INFORMATION PROCESSING MEMORY 1

WE ARE LEARNING TO... Understand the concept of selective attention and ways of improving it Identify the different parts of the memory and the functions of each QUIZ

DetectionComparison Recognition The process of recognising the stimulus, by the sense organs Making a comparison to previously stored experiences The process of recognising the most suitable choice and acting upon this decision This is related to perception Using your eyes, ears and touch to recognise the stimulus. The stimulus may be the flight/speed of the ball During this stage you will make a comparison to when you have been in this situation before and think about how you responded. For example, anticipating the height of the ball From all of your stored responses you then pick out the most suitable. This may be recognising that the ball has been hit high in Tennis and so angling your racket and jumping up to reach the ball

SELECTIVE ATTENTION The process of picking out and focussing on the parts of the display that are relevant to our performance During activity we receive a lot of info from our senses. We cannot recognise it all. We ignore the vast majority of it as it is irrelevant such as crowd noise etc... We try just to focus on the activity in question and aspects of the game which are directly of our concern

If we are more experienced in an activity they we can filter out irrelevant information more efficiently. If the important stimuli are bright in colour then we can interpret them better. E.g. a kit makes you identifiable Highlight/Cue/specific focus Practise – learn to ignore irrelevant stimuli (mental rehearsal) Make sure the performer is alert

Memory There are three stores in the memory: Short-term sensory stores (STSS) Short term memory (STM) Long term memory (LTM) There are three processes within the memory) Encoding (putting information into a store) Maintenance (Keeping it alive) Retrieval (Finding encoded information )

Look at the following items. Can you memorise them? You have 30 seconds to do so.

All information from the environment can be stored here. Has a huge capacity but only stored for half a second or less It is the first compartment of the memory which is subconscious and if not immediately attended to, information is lost Selective attention takes place here. If info is useful then it will be encoded Definition: A large capacity temporary store for all incoming sensory information

Definition: Also called the working memory. It relates to what we are thinking about at any given moment in time Encoded information is moved from the STSS to the STM. Information can be retained for up to 60 secs. It’s capacity is limited to 5-9 items Information only remains in the STM for as long as it is attended to. If attention is directed elsewhere, info is lost within 30 secs Important when learning skills. Need to be able to recall info bout performance so that you can compare it to previous performances Limited capacity means that instructions from the coach should be brief and given when the performer is paying attention, or info will be lost

Definition: A store of past experiences of almost limitless capacity and long duration All info in the STM is either stored in the LTM or is lost. The LTM is a store of well-learned past experiences It has a limitless capacity, vast, lasts a lifetime Information in the LTM is used to compare against new experiences. It stores responses to different situations

Exam Question Input of stimulus From Sensory Receptors SSTSSTMLTM Using the above model describe the main functions of the: (a)Short Term Sensory Store (2marks) (b)Short Term Memory (2 Marks) (c)Long Term Memory (2 Marks)
