QQWFDP P h Emotions are physiological arousal expressive behavior and conscious experience There is a cognitive and physiological element to them They have a particular internal feelingbodily response and they are either liked or disliked They cause external bodily outcomes Facial expressions etc They trigger action responses and cognitive responses Emotions do not last long moods last longer The motivate us for action They are explicit by evaluating cognitive appraisal and implicit by coding hedonicity i Both directly in uence our behavior They regulate social behaviors and help maintain selfesteem 3 Categorization of Emotion a Basic Emotions i Anger Attack AggressionConfrontation ii Fear Threat or Danger FightFlightFreezing iii Sadness Losses Seeking Comfort or Withdrawal iv Disgust BodilyMoral violation Rejection v Surprise Nonexpectation AlertnessInquisition vi Joy RewardGain AttachmentApproaching b NonBasic Emotions Emotional blends Social Emotions i Pride ii Embarrassment iii Guilt iv Shame V Maternal Love vi Sexual Love vii Infatuation viii Admiration ix J ealously 4 Basis of Emotions Physiology or Cognition a 99057 f Emotions can be seen as biological responses that we have little control over Or they can be de ned as a conscious experience rather than a biological response We are not good at detecting our levels of physiological arousal We recognize different emotions because of our mental evaluation of a situation Measurements of heart rate breathing and blood pressure can help determine emotions Selfreport questionnaires measure emotional experience 5 Theories of Emotions a Lange and James propose that emotional experience is a result of physiological arousal i This is the somatic theory of emotions ii The body informs the mind iii Body changes are accompanied by different emotions and perception of these changes determine emotions iv Differences in emotions are the direct results of different patterns of psychological responses V Distinctive patterns in the ANS are associated with different emotions Cannon suggest that arousal is a signal system for the brain to act and produce emotions i Emotions are emergency situations which trigger different brain processes ii A heightened arousal system prepares body to cope with situation iii The conscious emotional experience is registered in the cortex iv Instantaneous emotional feeling v Flawed because than people who do not receive physiological arousal should not experience emotions False autonomic feedback and Excitation transfer theory both suggest that there is more emotional experience than physiological arousal Two Factor Theory of Emotion i Physiological and situational factors play a role in emotion ii Autonomic arousal intensi es the emotion iii Physiological arousal determines the quantity of the emotion iv Cognitive attribution is the critical factor in emotional experience e Cognitive Appraisal Model i Cognitive appraisal determines the level of physiological appraisal and type of emotion we eXpect to experience ii We learn what to eXpect from previous stimuli f Pavlov i Classical Conditioning 1 CS gt US ii Instrumental Conditioning 1 RewardsPunishments Lecture 2 1 Issues of Affective Neuroscience a What are the underlying brain circuits b How emotional eXperiences emerge from the brain circuit i Emotional abilities are instinctual ii Organism39s learn to make effective behavioral choices in order to survive iii Different emotional tendencies emerge at different parts of development 2 History of Affective Neuroscience a Classical Psychoanalysis i Feelings and thoughts are everything while biology does not matter b Radical Behaviorism i Feelings and thoughts do not matter behavior is a set of learned responses c Timeline of Affective Neuroscience Print Slide 9 and learn dates circled in red 3 Major Theories a Somatic Marker Hypothesis i A key role for bodily feedback in emotion implicating the PCF where somatic markers are stored ii Somatic markers are physiological reactions that tag previous emotional events as significant iii Emotions are informations and feelings are monitors iv Somatic markers allow decisions to be made where logical analysis is impossible b Valence Asymmetry Hypothesis i Promotes adaptive goals by linking choices to emotional consequences ii Left PCF Positive goals iii Right PCF Negative goals c Emotion Systems i Single System Model A particular region is responsible for a particular emotion ii Multiple System Model Various regions serve for different emotions 4 Big Questions a Is pleasure simply a sensation i No it39s more of a cognitive emotion b Hedonic impact is added to pure sensation signal Is human pleasure similar or different than other animals i The same limbic brain circuit and neurochemical activity occurs but human cognition adds richness d Pleasure is not simply getting what you want it is getting what benefits you Liking is a hedonic value wanting is a drive e Can pleasure be assessed by objective measures i Basic core emotions can but cognitive functioning can not f Are pleasure and pain on a continuum i Pleasure is generally negatively correlated with pain but sometimes they are in uenced indirectly g Does pleasure have evolutionary function i Pleasure drives motivation and optimizes behavior h What brain substrates actually cause pleasure i A single area does not implicate pleasure Some must remain intact for hedonic value Lecture 3 1 Mind vs Brain Mental vs Neural a CellularMolecular Links emotional processes to action potentials local field potentials and neurotransmitter actions i Neural representation The way that neural transmissions respond to the outside world b Cognitive Links emotions to brain substrates i Mental representation abstraction relating to things in the external world ii Cognitive processes Thinking attention memory learning decision making interpretation c Stimulation of corteX produces mental sensations of thinking and memory 2 History of the Study of the Brain a Do mental experiences arise in the heart or brain b MindBody Problem How can a physical substance give rise to mental experiences i Dualism Mind and body are separate ii DualAspect Theory Mind and body are two levels of explanation for the same thing iii Reductionism The mind will eventually be explained in terms of physicalbiological terms c Early anatomists believed the ventricles were very important and the cortex was misrepresented d Phrenology i Different parts of cortex serve different functions still used Functional Specialization There is some degree of specialization but not each region does not have a specific function ii Differences in personality ability are represented in differences in the skull sizeshape and lumps discredited e Broca s Observation Specialized language faculty in brain i Patients with lesions in this area could not speak but had good cognitive abilities ii There are two language faculties in the brain 1 Comprehension 2 Production f Minds without Brains The Computer Metaphor i During the 20th century researcher were concerned with observations of behavior not what the brain was doing during behavior This lead to behavioral models that did not reference the brain ii This was inspired by thinking of the mind as following processes like a computer iii Input gt Perception gt Attention gt Short term memory gt Output g The Return of the Brains i Structural images allow precise imagining of the brain CT MRI ii PET adapted to models of cognition iii Levels of oxygen in blood measure cognitive functioning 3 Main Challenges a Is it possible to study the mind without the brain i Software Mind Hardware Brain ii Brain provides constraints on the nature of cognition iii It39s hard to give a purely cognitive answer but easy to answer in terms of neural processing b Functional imaging tells us where cognition occurs but not how i ii Lecture 4 Data tells us wherewhen Theory tells us how 1 Basic Knowledge of the Brain and its Units a Central Nervous System Brain spinal cord cerebrum and cerebellum i ii iii iv vi vii viii Has 100 billion neurons and
