Psychology Exam 2: Study Deck Flashcards
How do nature and nurture differ, and an example of each?
Nature refers to the genes we were born with that can impact how our personality is formed and influence the way we develop from childhood through adulthood; Nurture refers to the environmental factors that impact who we are.
What does variation (phenotypic) mean in natural selection?
The physical appearance of organism.
What is the human genome?
Complete instructions; all genetic material in chromosomes of organism.
What do studies of twins and fraternal reared apart and together show?
Identical twins who both reared together and apart are much more similar than fraternal twins reared together.
What does the graph “verbal ability over time’ show about the child-parent correlation in verbal ability scores?
The child is more similar to their biological mother either in the same household or with adoptive parents.
What do studies of twins show about identical twins than fraternal twins?
A human experiment studied identical twins and found that they were similar in personality and abilities.
What does differential reproduction mean in natural selection?
Individuals with favorable characteristics pass traits to the next generation.
What are the three ingredients of natural selection, and an example of it?
Variation, Differential Reproduction, and Heredity
What does heredity mean in terms of natural selection?
The genetic transfer of characteristics from parents to offspring.
What are the components of chromosomes?
Chromosomes: Threadlike structures made of DNA molecules that contain genes.
DNA (deoxyribonucleic acid): A spiraling, complex molecule, containing the genes that code instructions for the synthesis of proteins.
Genes are segments of DNA capable of synthesizing proteins.
What is the correlation between the heritability of disorders and twin study heritability?
Since twins share the same genes, and if one is more prone to developing a psychological disorder, the other is as well.
Fraternal twins result in
A. A single egg is fertilized by a single sperm and then splits.
B. A single egg is fertilized by two sperm and then splits.
C. Two eggs are fertilized by two sperm.
D. Two eggs are fertilized by a single sperm.
C. Two eggs are fertilized by two sperm.
Identical twins result in
A. A single egg is fertilized by a single sperm and then splits into two
B. Two eggs are fertilized by two sperm
C. Two eggs are fertilized by a single sperm
D. A single egg is fertilized by two sperm and then splits
A. A single egg is fertilized by a single sperm and then splits into two
How does the interaction of genes and environment work, and what is an example?
Genetic interaction with your environment can affect behavior.
Example: Temperament [mood] and Parenting.
One can have an agitated temperament and that could influence your parenting style, which can then be part of the environment that influences the behavior of your children.
What does self-regulation mean in terms of how the interaction of genes and the environment work?
Rather than acting as blueprints that lead to the same result, they result in the environmental context.
What does epigenetics mean in terms of how the interaction of genes and the environment work?
The study of how environments can trigger or block genetic expression.
Why might natural selection have resulted in greater male promiscuity?
Men who had the trait of promiscuity were more likely to have their genes continue and even spread, in the next generation.
What does the sexual double standard (SDS) imply about male and female sexual behaviors?
Male and female sexual behaviors should be judged by different standards, such as the belief that casual sex is acceptable for men, but not for women.
What does a double standard mean?
A rule or principle which is unfairly applied in different ways to different people or groups.
In terms of culture and the self, what do individualist cultures value?
Giving priority to one’s goals over group goals and defining one identity in terms of personal attributes rather than group identifications.
In terms of culture and the self, what do collectivist cultures value?
Giving priority to the goals of one’s groups (often one’s extended family or work group) and defining one’s identity in terms of group identifications.
From the very first weeks of life, infants differ in their characteristic emotional reactions, with some infants being intense and anxious, while others are easygoing and relaxed. These differences are usually explained as differences in ______________.
Tempermant
What does intersex mean?
A condition present at birth due to unusual combination of male and female chromosomes, hormones, and anatomy; possessing biological sexual characteristics of both sexes.
What two sex chromosomes determine a female vs a male individual?
X + X = Female
X + Y + Male
