Test Two Flashcards
Neuron
Nerve cells contains:
- Dendrites: receive stimulation
- Axon: Passes the message on
Hypothalamus
Lies underneath the the thalamus near the bottom center of the brain
- controls the pituitary gland and also regulates homeostasis (hunger, thirst, body temperature
Amygdala
Links perception and thoughts about the world with their emotional meaning
- Effects negative emotion: fear and anger
- Responsible for detecting fear and preparing for emergency events
Hippocampus
Processes memories
Cortex
Outermost layer of the brain
- Wraps around the hypothalamus, thalamus, amygdala and hippocampus
Neocortex
This is the largest part of the cortex
Frontal Cortex
This is divided into two lobes
- Aspect of cognition: ability to plan ahead and to anticipate consequences
- Aspects of emotional experience: empathy and moral reasoning
Electroencephalography (EEG)
Electrodes are placed on the scalp to pick up electrical signals generated by the brain activity
- Strengths: High temporal precision
- Weakness: Poor spatial localization
Megnetoencephalography (MEG)
Detect magnetic indications of brain activity
- Opposed to electrical
- Strengths: High temporal precision
- Weakness: Poor spatial localization
Positron Emission Tomography (PET)
Create a map of brain activity by following the location of a harmless radioactive tracer injected into the blood stream
- The harder the brain works the more blood it needs
- Follows blood flow
Functional Magnetic Resonance Imaging (fMRI)
Monitors magnetic pulses generated by oxygen in the blood to map where the brain is the most active at a given moment
- BOLD: blood oxygen level dependent
- BOLD compares how much the brain lights up from activity one to activity two
Somatic Marker Hypothesis
.
Corpus Callosum
.
Anterior Cingulate
.
Neurotransmitter
Communication between neurons
Synapse
gap between the neurons
Hormone
Biological chemicals that affect the entire body
Central Nervous System
brain and spinal cord
- epinephrine and norepinephrine work together here
Peripheral Nervous System
.
Endorphins
.
Serotonin
NAC
- stability
- neuroticism, agreeableness, conscientiousness
Gonads
testies and overies
Adrenal Cortex
.
Epinephrine
the fight in flight
- increases heart rate
Norepinephrine
the flight in fight
Oxytocin
the love hormone
Testosterone
high levels in males lead to agressiveness
- both male and females have this
Estrogen
.
Cortisol
relates to stress levels
- Regulates blood pressure
Personality Trait
.
Allele
.
Epgenetics
.
Mate Selection
.
Mating Strategies
.
Active Person-Environment Transaction
The person seeks out compatible environments and avoids incompatible ones
Cohort Effect
Birth year confounds the results: certain things were not the same in this year than 50 years ago
- Example: not everyone went to school, may effect the results
Cross-Sectional Study
Simply survey people at different ages simultaneously
Cumulative Continuity Principle
The idea that personality becomes more stable and unchanging as a person gets older
Heterotypic Continuity
Personality changes with age
- a shy child at a social even might hide behind a parent, a shy adult is unlikely to do that but still might avoid conversing with others
Evocative Person-Environment Transaction
Attributes of the individual draw out particular responses from others in their environment
Longitudinal Study
Same people are repeatedly measured over the years from childhood through adulthood
Maturity Principle
The idea that traits associated with effective functioning increase with age
- Tendency of socially adaptive traits to increase with age
- People become better equipped to deal with the demands of life as they acquire experience and skills
Narrative Identity
The story one tells oneself about who one is
- author for your life
Person-Environment Transactions
Processes wherein people respond to, seek out, and/or create environments that are compatible with or magnify their personality traits
- Aggressive person is attracted to another aggressive person
Personality Development
.
Rank-Order Consistency
People tend to maintain the ways in which they are different from other people the same age
- A person who is more extraverted as a child will maintain that same level of extravert as an adolescent, an adult and so on.
