Module 3 Journal (Go to FILE, the DOWNLOAD AS, and the pick a format that you can edit) Your journals are meant to help you take notes and study as you move through the modules. They should be completed little by little as you do each lesson, not as a stand-alone assignment to be done all at once. For each term the textbook definition has been provided to you. You will create an example, application, or other means of helping you remember the term. The last column should be written in a complete and grammatically correct sentence. It should not be a repeat of other examples. Term Definition or Description How will you remember? (Written in a complete sentence. Do not repeat previous examples.) 3.01: Sensation: Do You Feel It? 1. Synesthesia disorder in which the signals from the various sensory organs are processed in the wrong cortical areas, resulting in the sense information being interpreted as more than on sensation 2. Sensation The process that occurs when special receptors in the sense organs are activated, allowing various forms of outside stimuli to become neural signals in the brain. 3. Stimuli Anything in a person’s environment that can be picked up by the senses (e.g. dog
barking, smelly garbage) 4. Transduction Conversion of energy in the environment into messages our nervous system can interpret. 5. Just noticeable different (difference threshold) The smallest noticeable difference that can be detected between two stimuli. 6. Absolute threshold The smallest amount of stimulation that we can detect 50% of the time. 7. Habituation Tendency of the brain to stop attending to constant, unchanging information. 8. Sensory adaptation Tendency of sensory receptor cells to become less responsive to a stimulus that is unchanging. 9. Weber’s Law Law explaining that there is not a specific value for difference thresholds, but rather it is a constant proportion based on the size of the initial stimulus. 10. Signal Detection Theory A collection of concepts that seeks to explain how and why people will respond differently to the same stimuli under different circumstances. 11. Hit Correctly detecting a targeted situation when it is present 12. Miss Failure to detect a targeted situation when it is present 13. False alarm Incorrectly detecting a target that is not actually present.
14. Correct rejection Properly detecting no target when none is present. 15. Subliminal Any perception below the absolute threshold. 16. Adaptation Decreased sensitivity to stimuli occurring when sensory receptors become less responsive to fixed stimuli. 3.02: Vision & Hearing 17. Visual accommodation The change in the thickness of the lens as the eye focuses on object that are far away or close. 18. Rods Visual sensory receptors found at the back of the retina, responsible for non color sensitivity to low levels of light.
