MCAT Psych #10 Flashcards
interpersonal attraction
phenomenon of individuals liking each other
influenced by many factors, including physical characteristics, similarity, self-disclosure, reciprocity, and proximity.
interpersonal attraction: physical characteristics
Humans are attracted to people based on outward appearance such as more symmetric face or body proportions of the golden ratio.
interpersonal attraction: similarity
Attracted to people who are more similar (attitudes, age, height). Easier to hangout with these people.
• People like to have their values and choices validated
• Opposites attract: nurturer with someone who likes to be nurtured.
interpersonal attraction: self-disclosure
sharing one’s fears, thoughts, and goals with another person and being met with nonjudgmental empathy.
• Needs to be reciprocal
interpersonal attraction: reciprocity
the phenomenon whereby people like others better when they believe the other person likes them.
• Even if you disagree, if you think they like you, you will have increased interest in them.
interpersonal attraction: proximity
being physically close to someone
• Part of this is convenience.
• Ex: same dorm, sit close in class.
• Mere exposure effect or familiarity effect: people prefer stimuli that they have been exposed to more frequently.
o Ex: hearing a song and not liking it but then beginning to like it after 5 more times.
mere exposure/familiarity effect
people prefer stimuli that they have been exposed to more frequently.
o Ex: hearing a song and not liking it but then beginning to like it after 5 more times.
aggression
a behavior that intends to cause harm or increase social dominance. Physical and verbal
o Threat display can lead to bodily and physical harm ensuing or withdrawal of one of the parties
o Evolutionarily aggression offers protections against perceived and real threats.
o Parts of the brain contribute to violent behavior
Amygdala: part of the brain responsible for associating stimuli and their corresponding rewards or punishments.
• Tells us if something is a threat. When activated it increases aggression. The prefrontal cortex can pump the breaks on this.
o Cognitive neoassociation model: states that we are more likely to respond to others aggressively when we are feeling negative emotions, such as being tired, sick, frustrated, or in pain.
o Viewing violent behavior increases aggression.

attachment
an emotional bond between a caregiver and a child
o Development of attachment begins during infancy and is very important for the first two years of a child’s life.
o In attachment, a secure base is a caregiver who is consistent, available, comforting, and responsive.
attachment involves
child and caregiver (doesn’t have to be parent)
what are the four main attachment styles
secure attachment
avoidant attachment
ambivalent attachment
disorganized attachment
secure attachment
a child has a consistent caregiver and is able to go out and explore, knowing that he or she has a secure base to return to.
• Important for child’s social development
• Upset when the caregiver leaves and happy when comes back.
• Trusts that the caregiver will be there for comfort but will also take comfort form others.
avoidant attachment
the caregiver has little or no response to a distressed child.
• No distress when caregiver leaves and no relief when returns
• Show no preference between caregiver and stranger.
ambivalent attachment
the caregiver has an inconsistent response to child’s distress, sometimes responding appropriately, sometimes neglectfully.
• Distressed when caregiver leaves but mixed emotion when returns.
disorganized attachment
show no clear pattern of behavior in response to the caregiver’s absence or presence, but instead can show a mix of different behaviors.
• Associated with erratic behavior and social withdrawal by the caregiver
• Red flag for abuse.
sometimes exhibits repetitive behaviors or seems dazed and confused
secure base
is a caregiver who is consistent, available, comforting, and responsive.
social support
the perception or reality that one is cared for by a social network.
o Although it is present at all times, it is most pronounced and necessary when someone suffers a personal or family tragedy.
what are the different categories of social support
emotional support esteem support material support informational support network support
emotional support
listening, affirming, and empathizing with someone’s feelings
• Ex: I’m sorry for your loss card or visiting someone in the hospital
esteem support
touches more directly on affirming the qualities and skills of a person
• Ex: telling a school friend that has missed a lot of school that making up the work will be easy because they are smart.
material support
syn: tangible support
any type of financial or material contribution to another person.
• Ex: donating money or making a meal
informational support
providing information that will help someone
• Ex: doctor to patient explaining diagnoses.
network support
gives a person a sense of belonging.
• Ex: physical hug, gestures, group activities.

social support provides _____ benefits
health
foraging
seeking out and eating food, driven by biological, psychological, and social influence.
Bio: sensation of hunger is driven by the hypothalamus, genes dictate who in the group will do what foraging roles.
Cognitive skills such as spatial awareness, memory, and decision making play a role in the success of foraging.
• Species that forage as a group: learned through observation
lateral hypothalamus and what happens if damaged
hunger, always full
ventromedial hypothalamus and what happens if damaged
satiety, never full
mating system
describes the organization of a group’s sexual behavior.
monogamy
refers to an exclusive mating relationship
polygamy
o Polygandry: a male having exclusive relationships with multiple females
o Polygyny: female having exclusive relationships with multiple males
polygandry
a male having exclusive relationships with multiple females
polygyny
female having exclusive relationships with multiple males
promiscuity
a member of one sex mating with a member of the opposite sex, without inclusivity.
A member of one sex mating with ANY member of the opposite sex
mate choice or intersexual selection
dthe selection of a mate based on attraction
mate bias
how choosy members of the species are while choosing a mate.
• Evolutionary aimed at increasing the fitness of the species
• Direct benefits: providing material advantages, protection, or emotional support
• Indirect benefits: promoting better survival of offspring
5 mechanisms of mate choice
- phenotypic benefits
- sensory bias
- Fisherian or runaway selection
- indicator traits
- genetic compatibility
direct benefits
mate bias
providing material advantages, protection, or emotional support
indirect benefits
mate bias
promoting better survival of offspring
Direct benefits provide advantages to the ____. Indirect benefits provide advantages to the ____
mate
offspring
phenotypic benefits
mate choice
observable traits that make a potential mate more attractive to the opposite sex. Indicate increased production and survival of offspring.
Ex: males that are more nurturing
sensory bias
mate choice
development of a trait to match a preexisting preference that exists in the population.
Ex: pillar crabs building a specific territory that attracts mates (tricks them into thinking it is a food source)
Fisherian or runaway selection
mate choice
a positive feedback mechanism in which a particular trait that has no effect or a NEGATIVE effect on survival becomes more and more exaggerated over time.
Ex: peacock plumage, trait is attractive, more likely to get passed on
indicator traits
mate choice
traits that signify overall good health and well-being of an organism increase attractiveness to mates.
Ex: female cats like male cats with clean coat.
genetic compatibility
mate choice
the creation of mate pairs that, when combined, have complementary genetics.
Ex: being attracted to people who are very different reduces the probability of offspring being homozygotic for a disease-carrying allele.
altruism
a form of helping behavior in which the person’s intent is to benefit someone else at some cost to himself. Can be motivated by selflessness or egoism such as public recognition.
Empathy: the ability to vicariously experience the emotions of another
• Influences helping behavior
Empathy-altruism hypothesis: one explanation for the relationship between empathy and helping behavior: one individual helps another person when he or she feels empathy for the other person, regardless of the cost.
• Debated: maybe only when benefits outweigh costs.

game theory
attempts to explain decision-making behavior.
used to study decision making
A game is defined by its players, the information and actions available to each player at decision points, and the payoffs associated with each outcome.
evolutionary stable strategy
via natural selection, strategies are inherited traits passed along within the population, with the object of the game being becoming more fit than competitors.
