Personality Exam 2: Ch. 6, 8
| Question | Answer |
|---|---|
| what do people like *that* do?; focuses on one particular trait and its consequences for behavior; used to study conscientiousness, self-monitoring, and narcissism | single trait approach |
| who does *that*?; looks at relationships between a particular behavior and as many different traits as possible (i.e., California Q-Set) | many trait approach |
| which traits are the *most* important?; reducing the many to few | essential-trait approach |
| the single-trait approach of conscientiousness addresses characteristics such as (list 4) | integrity at work, job performance, purchase and maintenance of proper insurance, longer life expectancy |
| look to environment for clues to how they should act and feel; adaptable, flexible, popular, two-faced, lacking integrity | high self-monitor |
| look within; consistent, independent, honest, stubborn, distrustful | low self-monitor |
| excessive self-love; charming, good first impression, tend to be good-looking, manipulative, entitled, arrogant | narcissism |
| people who score high on narcissism may | become aggressive when threatened, not handle failure well, argue, exhibit road rage |
| 100 personality phrases sorted into forced choice, symmetrical, and normal distribution, allow one hour to complete, limited use with those who understand the instructions | California Q-Set |
| the important aspects of human life will be labeled, and that if something is truly important and universal, many words for it will exist in all languages | the lexical hypothesis |
| – tense, anxious, nervous, moody, worrying, touchy | neuroticism |
| wide interests, imaginative, intelligent, insightful, curious, sophisticated | openness to experience |
| talkative, assertive, outgoing, dominant, enthusiastic, sociable, spunky, adventurous | extraversion |
| sympathetic, kind, appreciative, affectionate, soft-hearted, warm | agreeableness |
| organized, thorough, efficient, responsible | conscientiousness |
| which two traits of the Big Five increase with age as individuals take on more responsibilities? | agreeableness and conscientiousness |
| ____ decreases with age, while ___ and ___ show more complex patterns of change | neuroticism, openness, extraversion |
| questions regarding ___: what can the structure of the brain tell us about personality? | anatomy |
| Questions regarding ____: to what degree is personality a matter of chemistry? | physiology |
| a network of neurons in the brainstem that regulates wakefulness, arousal, and attention; filters sensory information | ascending reticular activating system (ARAS) |
| introverts have a wide-open ARAS, leading to over-arousal, while extroverts have a closed-off ARAS, leading to under-arousal | Eysenck's Theory |
| almond shaped structure located deep in the brain's temporal lobe that processes emotions; abnormal functioning linked to anxiety, depression, autism, PTSD, phobias | amygdala |
| regulates arousal and serves other functions | thalamus |
| secretes hormones (biological chemicals that affect the entire body) | hypothalamus |
| processes memories | hippocampus |
| control of body movement humans’ response to reward/reinforcement learning part of the basis of sociability contributes to general activity level trait of novelty-seeking; impulse control Regulating emotions Motivation, pleasure, attention | dopamine |
| dopamine spikes when | Reward anticipation (expecting something good) Goal achievement Novelty (new stuff) Risk-taking |
| lack of dopamine (dopaminergic dysfunction) has been linked to | Has been linked to Parkinson’s-like symptoms (tremors, slow movement |
| personality effects from little dopamine | Low extraversion Reduced drive/motivation Diminished reward response (things do not feel as good) |
| behaviors from excess dopamine | Impulsivity Risk-taking Novelty seeking “Chasing the high” behavior pattern |
| Emotional regulation Mood stability Anxiety control Appetite Sleep Inhibition of impulses Some inhibition of emotional impulses can help people: avoid excessive worrying and decrease their sensitivity to the environment | serotonin |
| lack of serotonin or serotonin depletion syndrome linked to | irrational anger, hypersensitivity to rejection, chronic pessimism, obsessive worry, and fear of risk taking/excessive risk aversion |
| high serotonin (serotonin syndrome) is __ but people exhibit ___ | rare, usually from medication misuse agitation, confusion, increased heart rate, tremors |
| prevent serotonin reabsorption and increases available serotonin in brain synapses; more serotonin hanging around = better mood regulation; less clear | selective serotonin reuptake inhibitor (SSRI) |
| outer layer of the brain that has six different layers | cortex |
| outermost layer of the brain that is more complex and wrinkled than the cortex in other animals | neocortex |
| divided into two lobes on the left and right sides; ability to plan ahead and anticipate consequences, emotional experience (empathy and moral reasoning) | frontal cortex |
| nerve cells | neurons |
| brain stimulation that uses rapidly changing magnetic fields to temporarily "knock out" (turn off) areas of brain activity in order to learn more about their functions | transcranial magnetic stimulation (TMS) |
| a related technique that shows that the right frontal lobe is important for making morally relevant decisoins | transcranial direct current stimulation (tDCS) |
| electrodes are placed on the scalp to pick up electrical signals generated by the brain activity underneath (when) | electroencephalography (EEG) |
| uses delicate sensors to detect magnetic indications of brain activity (when) | magnetoencephalography (MEG) |
| brain imaging devices limitations | a researcher must do more than simply measure what the brain does |
| computers allow many different images from multiple angles to be combined into representations of very thing slices (tomographs) of the brain, allowing minute structures to be examined (where) | computed tomography (CT) scans |
| creates a map of brain activity by following the location of a harmless radioactive tracer injected into the bloodstream (where) | positron emission tomography (PET) |
| monitors magnetic pulses generated by oxygen in the blood to map where the brain is most active at a given moment | functional magnetic resonance imaging (fMRI) |
