About sensation, perception and attention notes
GoConqr OriginalUsing sensation, perception and attention notes
Start with the notes on sensory processing for a short introduction to sensation and perception. They set out the terms before moving on to how sensations are integrated. For a broader view, Sensation and Perception is another place to explore the unit.
Other notes focus on particular topics. The lecture notes on colour cover luminance and the visible spectrum. Perception in brief looks at perceptual organisation, while Cognitive Neuroscience notes covers attention, including spatial and feature attention.
From reading to recall
Read a section, then close the note and write down the key terms you remember. Reopen it to check what you missed. The visual cortex pathway in Short Answer Questions gives you a topic to practise explaining in your own words.
When you want a different way to review, switch to a mind map on the unit page to see connections, or use a quiz to check your recall. Pick a note and give that approach a try.
Frequently asked questions
Which note should I start with?
The notes on sensory processing are a useful starting point because they introduce the terms stimulus, sensation and perception. Read those definitions first, then try explaining them in your own words. You can move on to a more focused note when you have chosen a topic to review.
Do these notes cover attention as well as perception?
Yes. The page includes notes on auditory attention and <strong>Cognitive Neuroscience notes</strong>, which covers attentional processing and spatial and feature attention. For perception, you can explore notes on sensory processing, colour, perceptual organisation and the visual cortex pathway.
Are these notes free to use?
Yes. Every resource listed here is free to open and study without an account. The notes were made by GoConqr users, rather than by GoConqr. A free account also lets you save quiz scores and make your own quizzes, mind maps, flashcards and notes.
