| Question | Answer |
| Fundamental Paradigm | When an idea of the world changes fundamentally from A to B |
| The mind and the brain is | an information processing machine |
| The brain and the sensory systems are | The origins of all mental events |
| Sensory channels are thought of as | Data filters |
| Psychology is | the study of the human mind and its functions, especially those affecting behaviour |
| Perception is | a conscious sensory experience of high-level processing, usually related to activity in the cortex |
| Sensation is | an automatic and unaware collection of low-level information |
| Sensation and perception are | difficult to separate |
| Both the sensory system and perception | are essential for an autonomous agent to survive |
| Senses allow us to | Collect and interpret sensory information in order to perceive the world and build a representation, and perform daily actions based on this perception |
| Performing actions based on perception | is done effortlessly on a day to day basis which is why perception is so important |
| E.g. eating an apple | presence of the apple is recognised by the senses. We then recognise the concept which triggers a behavioural response of grasping and eating, or avoiding if it's rotten. Evolution arguably shaped these systems to make them efficient or reliable |
| Perception can be described as | the window between the physical world and the mental state |
| We are surrounded by | the outside world but what we really experience is inside our mental state |
| Our senses act as | a channel to collect information |
| Information processing | converts the world into internal events |
| sensation and perception are the | starting points for higher cognitive processes in a network of information processing |
| Higher cognitive processes are | attention, memory and thinking which leads to behaviour / action |
| Attention helps us to | select important sensory information which is then passed to the memory. We then think about it which leads to the control or action of behaviour |
| Attention does influence | what we perceive. Therefore our perceptions are biased by what we know. |
| Psychologists are divided over | how much perception relies on the information present in the stimulus |
| Bottom-up processing | Stimulus information arrives from sensory receptors (the bottom of information processing) |
| Top-down processing | Stimulus information arrives from contextual information. This helps to organise the perceived stimulus using memory and knowledge |
| Example of top-down processing | Reading difficult handwriting is easier in a sentence than isolated words. This is because the meaning of surrounding words provide context to aid understanding |
