Reading Guide Baddeley Ch 13 Two points about aging Aging and cognitive processing Fluid vs crystallized intelligence Working memory and aging Executive deficits Speed-accuracy tradeoffs Advantages of experience: typists Aging and the components of Baddeley’s model Executive Chess Language Grammar Pronouns left-branching sentences Topics Writing Phonological loop Visuospatial scratch pad Long-term memory Recall vs recognition Strategies & training Self-performed tasks (hmm…how might this relate to what you know about levels of processing?) Prospective memory Supported vs unspported – we’ll talk about this more in class Semantic memory Bad news Good news Implicit learning Spared: Impaired: Biological influences Homeostatic regulation (in this case, glucose) Competitive stress Distraction Individual differences Average age of decline Factors that influence: Alzheimer’s disease (Baddeley doesn’t have the most accurate / up to date information on all aspects of this disorder. We’ll go over this more in this class and when we talk about memory diagnosis and amnesia) 8 aspects of cognition Problems with diagnosis Long-term memory in AD Semantic memory – the symptoms Baddeley describes here don’t kick in until mid-to-late stages of the disease in AD, although they are more prevalent in a related disorder called frontal-temporal dementia Implicit learning in AD Role of encoding deficits Working memory in AD Digit span Corsi block Recency effect in free recall Executive component? Dual-task coordination Treating Alzheimer’s disease Baddeley is mis-stating the case when it comes to acetylcholine. The current most common prescription is for an acetylcholinesterase inhibitor – in other words, a drug that stops acetylcholine from breaking down. It is not a cure, but it does seem to delay symptoms. I have worked with many, many AD patients, and they didn’t’ smell like bad fish!
