What is Cognitive Psychology?
Cognitive Psychology is the scientific study of thought and experience
Information Processing Approach
Humans as “stimulus response
machines”
- Information comes in through
the senses
- It is processed by a series of
modules that change the
information in a systematic way
- The output of this processing
modules ultimately cause an
observable response
Assumptions of Information Processing Approach
- Serial processing: Only one step
at a time - Bottom-up processing: all
processes are directly triggered
by the stimulus
STIMULUS => Attention => Perception => Thought processes => Decision => RESPONSE/ACTION
Criticism of Information Processing Approach
Does not allow for parallel
processing
- Ignores top-down processing, i.e. influences of an individual’s prior
knowledge, goals, and expectations
- Oversimplification
Bottom-up processing: Representation in our heads
- If you can have a thought about it, then ‘it’ exists in your neurons
- Image is represented in your head by the activity of a large number of neurons, although it looks and feels like something meaningful to you]
Rate coding
Greater rate of a neuron’s response is used to code/represent info
Temporal coding
- Greater synchrony of the responses of several neurons is used to code information
(e.g. to bind together different aspects of an image, like
colour, motion, shape, …)
