Question 1

Aggression and striving for dominance are more common in

Accepted Answer

Research has consistently shown that males exhibit more aggression and strive for dominance more often than females. This trend is observed across species, including humans. Therefore, option D is the correct choice.

Question 2

Parents enhance the survival of their genes by

Accepted Answer

Nurturing their children enhances the survival of their genes because it increases the likelihood that their children will survive to adulthood and also have their own offspring, passing on the parents' genes to future generations. Having only one child or adopting children may not necessarily enhance the parents' genetic survival, as those children may not pass on the parents' genes. Abusing children would likely decrease their chances of survival and therefore decrease the parents' genetic success.

Question 3

Imitating others is made possible biologically by

Accepted Answer

Mirror neurons are specialized brain cells that fire when someone observes another person perform an action, and this firing allows the observer to imitate that action. They play a key role in social communication and learning, allowing us to learn through mimicry and to empathize with others.

Question 4

Reportedly, Hilary Rodham Clinton has always been bold and assertive. This early display of these traits suggests the influence and importance of _____ in the development of her personality.

Accepted Answer

Biological predispositions refer to the inherent traits and characteristics that an individual is born with, which can influence their personality development.

Question 5

Specific processes that have evolved because they solve particular adaptive problems of survival are called:

Accepted Answer

Specific processes that have evolved to solve particular adaptive problems of survival are called evolved psychological mechanisms. These mechanisms are produced by natural selection because they increase the chances of survival and reproduction in the environment in which they evolved.

Question 6

Sexual jealousy

Accepted Answer

Sexual jealousy is widely believed to be an evolved psychological mechanism that has developed through natural selection. It is triggered by the perception or suspicion of a partner's infidelity and serves the function of protecting one's genetic investment in the relationship. While there may be some individual and cultural variation in the expression of sexual jealousy, its basic foundations are believed to be innate and universal. Therefore, options B and C are not accurate.

Question 7

Evolved psychological mechanisms include all of the following except

Accepted Answer

Temperament is typically considered a dispositional trait, rather than an evolved psychological mechanism. The other options (imitation, sexual jealousy, and sexual attraction based on physical appearance) are all examples of evolved psychological mechanisms.

Question 8

Evolutionary theory has implications for

Accepted Answer

Evolutionary theory provides explanations for various aspects of human behavior, including aggression, altruism, and sexual behavior. It suggests that these behaviors have evolved over time because they helped our ancestors survive and reproduce in their environments. Therefore, understanding evolutionary theory is important for understanding these complex human behaviors.

Question 9

When it comes to reproductive potential, men may choose to do which of the following?

Accepted Answer

Men have various choices when it comes to reproductive potential. They may choose promiscuity to mate with multiple partners and increase their chances of passing on their genes. On the other hand, they may choose to have children with one woman and then stay to protect and provide for them. Additionally, men may also choose not to have children but help care and protect the children of their kin, allowing their genes to be passed on indirectly through their relatives. Therefore, all the above options are valid choices for men when it comes to reproductive potential.

Question 10

Sexual fidelity, according to evolutionary theory,

Accepted Answer

According to evolutionary theory, females have a greater investment in offspring than males, as they have a limited number of eggs and carry the burden of gestation and nursing. This leads them to be more selective in choosing a mate and to value sexual fidelity more than males, who can impregnate multiple partners with little physical cost. Therefore, sexual fidelity is greater in females than in males.

Question 11

Which statement best describes the relevance of evolutionary theory for culture?

Accepted Answer

Cultural evolution is a branch of evolutionary theory that studies the transmission and transformation of cultural traits over time. This means that evolutionary theory includes cultural evolution as a significant aspect of the evolution of human societies. Therefore, option D is the best answer. Options A, B, and C are incorrect as they present a false dichotomy between evolutionary theory and cultural explanations, rather than acknowledging that the two are complementary and can work together to provide a more comprehensive understanding of human behavior and culture.

Question 12

Studies of rats deprived of maternal contact showed that the rats developed permanent deficits in the hippocampus. Such deficits (in rats or humans) could make them more vulnerable to

Accepted Answer

Studies have shown that deficits in the hippocampus can lead to difficulties in regulating emotions and may contribute to the development of depression. Aggression, introversion, and sexual promiscuity have not been directly linked to deficits in the hippocampus.

Question 13

The fundamental assumption of evolutionary approaches is that

Accepted Answer

Evolutionary approaches are based on the assumption that genetic variations that contribute to reproductive success will increase in frequency over generations through the process of natural selection. This is the central concept of evolution by natural selection, which explains the diversification and adaptation of biological species over time. The other options (B, C, and D) are not accurate descriptions of evolutionary theory.

Question 14

Parental uncertainty

Accepted Answer

Parental uncertainty is typically greater in males than in females because males cannot be certain that they are the biological fathers of their offspring, whereas females have certainty about their maternity. This uncertainty can lead to behaviors such as sexual jealousy in males rather than females.

Question 15

According to evolutionary theory, altruistic behavior has survival advantages

Accepted Answer

Altruistic behavior can have survival advantages when it enhances the survival of one's children (A), other relatives (B), or other members of one's group who are not one's relatives (C). This is because individuals who engage in altruistic behavior may receive reciprocal benefits or increase the likelihood of passing on their genes through the survival of their kin or group members. Therefore, all of the above choices are correct.

Question 16

Altruism, according to evolutionary perspectives, is most directly caused by

Accepted Answer

Evolutionary perspectives suggest that altruism is most directly caused by the emotion of empathy, as it promotes survival and reproduction of individuals who share genes with the altruistic individual. Empathy allows individuals to feel the emotions and experience of others, leading to actions that benefit the group as a whole. Reasoning and experience may play a role in altruistic behavior, but they are not the primary cause. The emotion of happiness may be a byproduct of altruistic behavior, but it is not the direct cause.

Question 17

In cultures with equal status for men and women,

Accepted Answer

In cultures with equal status for men and women, sex differences in factors that contribute to sexual attraction are reduced. This is because when there is equal status, there is less emphasis on traditional gender roles, and individuals are more likely to look for personality traits and common interests rather than just physical attractiveness or status.

Question 18

Evolutionary theory describes that sexual attraction is greatest toward

Accepted Answer

According to evolutionary theory, sexual attraction is greatest towards physically attractive partners because traits such as symmetry, clear skin, and a healthy physique are indicators of good genes and overall health, increasing the chances of producing healthy offspring.

Question 19

The sexes differ in attitudes toward sexual promiscuity, according to evolutionary theory, because of

Accepted Answer

Evolutionary theory posits that males and females have different strategies when it comes to reproduction because of differences in parental investment. Females typically invest more time, energy, and resources into raising their offspring than males do, as they carry and nurse the baby. Thus, women have evolved to be more selective about sexual partners, as they want high quality mates who will provide protection and resources for their offspring. Men, on the other hand, have less of an investment in each offspring and are able to mate with multiple partners, which increases their chances of passing on their genes. Therefore, differences in attitudes toward sexual promiscuity are primarily due to differences in parental investment between males and females.

Question 20

How does evolutionary theory explain people that choose to be celibate? People that choose celibacy

Accepted Answer

Evolutionary theory suggests that kin selection plays an important role, meaning that individuals may still contribute to the well-being of the species by taking care of their kin who can reproduce. This may explain why some individuals may choose celibacy but still care for their siblings, nieces, or nephews, who may have children and pass on their genes to the next generation.
