<p> THE VISUAL PERCEPTION SYSTEM</p><p>1. What is sensation defined as?</p><p>2. What is perception?</p><p>3. What makes up the visual perception system?</p><p>4. Define visual sensation and visual perception – is there a place where one begins and the other ends?</p><p>5. Draw a flow chart to show the path of visual sensation and perception. On it, mark where light energy is detected, transduced, transmitted and then selected, organised and interpreted.</p><p>6. What’s the formal name for detecting changes in light energy?</p><p>7. Where does this happen, what does the job – and what is the outcome of detection?</p><p>8. What form of energy is used in transduction? – define transduction as well.</p><p>9. What is electrochemical energy and how does our body use it in vision?</p><p>10. Tranmission is?</p><p>11. Name (in order) the pathway used to transmit images to the occipital lobe.</p><p>12. What is meant by selection?</p><p>13. Box 2 – What are feature detectors and how do they work?</p><p>14. What is a visual field and how is this different to a receptive field?</p><p>15. Once the sensory information has been received, how is organisation carried out?</p><p>16. What is interpretation, then?</p><p>17. Box 3 – What does this let us know about the interactive nature of perceptual systems?</p><p>18. What are 2 factors that influence the organisation and interpretation of incoming sensory information?</p><p>19. Think up another example to explain the mix of factors.</p><p>20. What are the psychological factors that cause individual differences in our perceptions?</p><p>21. What other factors may affect visual perception?</p><p>22. What does the text say about the interactive nature of our perceptual systems</p><p>23. Try and explain in your own words, what light IS and how it is detected, by receptors. It may be useful to make a mini concept map to sort out the information here.</p><p>24. What does the term ‘threshold’ mean?</p><p>25. What is an absolute threshold? Give an example.</p><p>26. What’s a differential threshold? Give an example.</p><p>27. What is the signal detection theory?
