Apo lipoprotein E (APOE)V. Other Disorders with Alzheimer’s Dementia SymptomsVI. Multi-Infarct DementiaOutline of Current LectureI. Pick’s DiseaseII. Depressive Pseudo DementiaIII. Basic Cognitive Functions – Information ProcessingIV. Attention (and Memory)V. Automatic ProcessingVI. Aging and DrivingCurrent LectureI. Pick’s Diseasea. Not commonb. More womenc. Onset 40-60 years of aged. “Pick bodies” in Frontal/Temporal lobese. Personality changes firstf. Socially inappropriate behaviorg. Linguistic problemsThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.h. Memory fairly well intactII. Depressive Pseudo Dementiaa. 30% of all dementiasb. Symptoms:i. Apathyii. Psychomotor slowingiii. Impaired concentrationiv. Delusionsv. Confusionvi. Complain at memory lossIII. Basic Cognitive Functions – Information Processinga. Information Processing:i. Attention1. Aging & Driving2. Memory3. Factors that can influence memory4. Memory training studiesIV. Attention (and Memory)a. Questions:i. Under what conditions do older adults have trouble?ii. Why are there age-related deficits when they do exist?iii. Organization Problem?iv. Processing Deficits?b. Selective Attention: ability to distinguish relevant from irrelevant informationc. Visual Search Task: Identify whether or not target is present in a displayi. Target & Distractorii. Selectively attend to target while filtering distractorsiii. Age-Related Declinesd. Divided Attention: Ability to simultaneously process 2 or more sources of informationi. Large age differencese. Sustained Attention: Actively process incoming information over a period of timei. Vigilance task1. The Mackworth Clock Testf. Theories of Attention and Agingi. Attentional Resources Theory – Aging reduces available cognitive resourcesii. Inhibitory Deficit Hypothesis – Aging reduces ability to tune out irrelevant informationiii. Context Processing Deficiency Hypothesis – Aging reduces the ability to take context into accountg. Attentional Resources: Limitedh. Effortful Processing – takes a lot of effort/focus to doi. Large age-related deficitsii. Novel tasksiii. Draws upon limited attentional capacityV. Automatic Processinga. Task components no longer require attentionb. Well practiced taskc. Occurs without intentiond. Runs to completion once initiatede. Does not consume attentional resourcesVI. Aging and Drivinga. Bio = physical changes affect drivingb. Psycho = cognitive changes affect driving changes affect identityc. Social = Driving and independence, Practical implications, Ageist Attitudesd. Types of Accidents:i. Younger adults = speed & alcoholii. Older adults = Intersections, especially left hand turnse. Implicationsi. Attention Selection, Attention Shiftingii. Role of Inhibition?iii. Attentional Failures?iv. Benefit from cues – Red light w/ signal to wait until left turn
