Psychology 1100 Final Exam Review Session ● Functions of brain - (-70mV is resting potential) ● Conditioning (9-10 questions of exam 2) - Spontaneous never recovers a full strength - Spontaneous recovery ● Textbook: only read topics in syllabus - Chapter 8 - Priming ● Implicit memory: unaware memory ● Trace consolidation: The way short term memory must exist in your brain, is what’s on your mind right now. An active process. Active thing in the brain (neurons signaling) - Dynamic pattern of ongoing activity. - Long term memory: stuff you know that you’re not thinking of right now. Trace consolidation makes it so you can bring information from long term memory into short term memory. - Through elaborative encoding, you're committing short term memory and making a permanent pattern out of it to commit to LTM. Now you can bring forth info in the LTM to STM. - Forming LTM forms a structural pathway in the brain. Pathway for everything you’ve ever learned. - Traces on information you’ve associated with stimulus lead you to the actual anchored stimulus in your brain. ● Sensation vs. Perception*: Experiencing vs Knowing - Visual experiences leads to sensation of seeing colors. (certain wavelengths transmit the color blue) - Perception: Knowing what you’re seeing (ex: blue shirt) ● No ?’s on Split brain patients ● Distal Stimulus: the thing you’re receiving (ex: dog, tree) ● Proximal Stimulus: Projection of the stimulus onto the retina. Little upside image. Retinal Image. ● Lateral Inhibition: Neighboring receptor cells tend to inhibit each other (using inhibitory interneurons to connect them). The result is an exaggeration of contrasts: dark looks darker and light looks lighter - An example is brightness contrast: neighboring regions of different brightness have their boundaries sharpened as their brightness/darkness difference is increased. - Emphasized boundaries ● Weber’s Law: Just noticeable difference j.n.d. Change in intensity over intensity is constant. - One question about this. ● Psychophysics: relation of physical variables of environment to sensations in our experience. To be detected, intensity must exceed the absolute threshold. For a change to be detected, intensity must
