TB8 B&B Lecture 4; Control of Memory 0.0 / 5 ? PsychologyTB8 B&BUniversityNone Created by: mint75Created on: 26-04-16 13:29 What characterises the default mode network (task negative)? Common brain areas always DEACTIVATED during tasks 1 of 21 Which structure is NOT included in the default mode network? Orbitofrontal cortex 2 of 21 What is a function of the ventrolateral PFC? Effortful retrieval with LOTS of competition (Left IFG selective attention) 3 of 21 What is the subsequent memory effect? Where activity at encoding predicts subsequent memory success 4 of 21 Where does activity at encoding predict subsequent memory success? VLPFC & Hippocampus 5 of 21 What is retroactive interference in retrieval? New learning interfereing with retrieval of an old memory 6 of 21 What is proactive interference in retrieval? Old learning interfering with retrieval of a new memory 7 of 21 Following damage to PFC, which is poorer; recall or recognition? Recall poorer than recognition 8 of 21 Following damage to the PFC, is source memory (discriminating between similar memories) affected? Yes 9 of 21 What is confabulation? Failure to inhibit irrelevant thoughts & detect implausible responses 10 of 21 What is the difference between semantic dementia and semantic aphasia? SD = Degradation of amodal semantic representations, SA = Deregulated semantic retrieval 11 of 21 Knowledge v.s control processes = which impairments? Semantic dementia v.s Semantic Aphasia 12 of 21 Forgetting as...? A need to control competition processes in retrieval 13 of 21 Reduced activation of VLPFC...? Retrieval induced forgetting task is easier, forget competing mems more 14 of 21 Behavioural control is? The ability to control actions based on goals, go-no go task. 15 of 21 Cognitive control is? The ability to flexibly control thoughts in accordance with goals. Think-no think task. 16 of 21 Which brain structures are involved in Think-no-think (Anderson et al 2004)? Left IFG and DLPFC 17 of 21 Development of PTSD following trauma...? Linked to difficulty in using VLPFC to suppress unwanted memories 18 of 21 What is linked to poor source memory and confabulation? PFC damage 19 of 21 What is linked to deficits in controlled semantic retrieval in semantic aphasia? Left IFG damage 20 of 21 Can forgetting be positive? Yes 21 of 21
