Introduction to Biological Psychology Exam 5 – Study Guide Chp 14: Higher Cognitive Functions Know the concept of executive functions and component processes (e.g. working memory, inhibition, etc) Executive Function processing is done by multiple systems Executive Control involves being able to process/devote reasoning relative to a goal Working Memory activated task-relevant information Inhibition 1) preventing distracting information from gaining access to working memory 2) preventing an alternative, goal-irrelevant response from occurring Perseventive Behavior applying initial rule over and over even though told it is incorrect Know the components of attention (e.g. orienting and detection) and brain regions involved Orienting Posterior Parietal Association Cortex (lesions produce contralateral neglect) Detection Anterior Frontal Association Cortex (lesions produce difficulty shifting focus of attention) Be familiar with contralateral neglect Contralateral Neglect ignoring a part of the body or world on the side opposite (i.e. contralateral) that of a brain injury Know the subdivisions of the frontal cortex Anterior Frontal Association Cortex involved in selective, conscious processing (attention) -damage: inability to focus on goal Lateral Prefrontal Cortex working memory center, currently activated task-relevant information, manipulation of information within working memory, source memory and memory for temporal information, flexible thinking, planning, inhibition DLPFC plays a role in actively maintaining information, task switching Anterior Cingulate Cortex conflict monitoring Ventromedial/Orbitofrontal rational decision making/ social and emotional judgment Know the definition of working memory and Baddeley’s model of WM Working Memory currently activated task-relevant information Baddeley’s Model of Working Memory Viseo-spatial Sketchpad  Central Executive  Phonlogical Loop Know the brain region involved in working memory, source memory and temporal order DLPFC Be familiar with cellular mechanisms of working memory (e.g. single cell recordings) Monkey trained to release bar when a stimulus/location pair was given: -Neurons can learn to respond selectively to information in their receptive field (neuron is the computational unit of cognition) Be familiar with tasks used to assess executive functions

WCST given a cue card, then 4 other cards, asked to sort by different categories, then told whether category is correct or no, after 10, told incorrect, key: can you adapt to a new rule? (if not, possible damage to frontal lobe) Stroop slowest during response conflict/competition condition (incongruent) Recency Judgment ask to order something relative to another item (recognition spared, but recency judgment not) Know the hypothesized role of the anterior cingulate in executive functions (e.g. conflict monitoring) Anterior Cingulate conflict monitoring/ context maintenance (bias task-relevant pathways) Be familiar with the work on split-brain patients
