Cognitive Psychology
What is Cognitive Psychology? The cognitive approach helps us understand how mental processes shape our behaviour Cognition means knowing: how we come to know the world around us
Cognitive psychology 3 The cognitive approach It is about the way people deal with information. We can receive sensory information, change it, store it, use it and process it in different ways. We can use existing knowledge to help us to interpret new information. Cognition includes a range of different mental activities: attention perception memory decision-making language. How do we take in sensory information?
How we take in sensory information
Cognitive Psychology - Sensation vs. Perception Our senses encode information accurately (sensation) Then our mind interprets it according to what makes most sense (perception) Cognitive processors actively organise and manipulate information that we receive – humans do not merely passively respond to their environment
The human mind is compared with a computer – we are information processors
How do we perceive the world ? Can we believe the evidence of our own eyes? Do we all ‘see’ the same thing? Is seeing innate? Or is it learnt?

In this illustration, the stairs should turn upside down during a steady gaze. The wall with the floating glass sphere will shift from the foreground to the background (or vice-versa)
Stare at the picture (on the left) for about 45 seconds Stare at the picture (on the left) for about 45 seconds. Then, stare at the white section of this image (the right section).

By looking at exceptions we learn more about memory http://www.youtube.com/watch?v=OmkiMlvLKto
If you are fascinated by these concepts…. Check out this film http://www.echalk.co.uk/amusements/OpticalIllusions/pinwheel/pinwheel.html Just for fun
You will be learning about 2 different theories of memory I am going to tell you a story…………
