1. The genetic influences that determine behavior may never be fully understood due to ________

Correct answer: B

Rationale: The correct answer is B because most behaviors are influenced by a complex interaction of many genes and the environment. Choice A is incorrect because it states that it is easy to differentiate between the effects of the environment and genes, which is not the case. Choice C is incorrect because although twin studies are commonly used in genetic research, this alone does not hinder the full understanding of genetic influences on behavior. Choice D is incorrect because even though we have some understanding of how genes impact brain chemistry, this does not mean that we fully understand the genetic influences on behavior.

2. Who proposed that the study of consciousness should be replaced by the study of behavior?

Correct answer: A

Rationale: The correct answer is John Watson. Watson, a key figure in behaviorism, believed that psychology should focus on observable behavior rather than consciousness. Abraham Maslow is known for his hierarchy of needs theory and humanistic psychology, not for advocating the study of behavior over consciousness. G. Stanley Hall was a pioneer in psychology but did not propose replacing the study of consciousness with behavior. Sigmund Freud, a prominent figure in psychoanalysis, focused on the unconscious mind rather than behavior.

3. John Bowlby's attachment theory emphasized ________.

Correct answer: B

Rationale: John Bowlby's attachment theory emphasized the quality of parental care in forming attachments. This is because Bowlby believed that a child's early experiences with their primary caregiver, especially the quality of care and responsiveness received, significantly influence the child's ability to form secure attachments. Choice A is incorrect because while the social environment plays a role, Bowlby's theory focused more on the caregiver-child relationship. Choice C is incorrect as it does not capture the central role of parental care highlighted in Bowlby's theory. Choice D is also incorrect as Bowlby's theory actually emphasized the importance of a secure attachment to parental figures for healthy emotional development.

4. _______ tends to be seen in American children, whereas _______ tends to be seen in Thai children.

Correct answer: C

Rationale: The correct answer is C: 'Undercontrolled behavior tends to be seen in American children, whereas overcontrolled behavior is seen in Thai children.' This statement is supported by cultural studies and observations. American children are often described as exhibiting undercontrolled behavior, which includes impulsivity and lack of inhibition. On the other hand, Thai children are often described as showing overcontrolled behavior, characterized by restraint and adherence to social norms. Choice A is incorrect because calm behavior is not typically associated with American children. Choice B is incorrect as overcontrolled behavior is not commonly associated with American children. Choice D is incorrect as there are observed differences in behavioral traits between American and Thai children.

5. What is the term for the age of an unborn baby, usually dated from the first day of an expectant mother's last menstrual cycle?

Correct answer: D

Rationale: The correct answer is D, Gestational age. Gestational age is calculated from the first day of the expectant mother's last menstrual cycle, providing an estimate of how far along the pregnancy is. Mental age (choice A), refers to an individual's level of cognitive functioning in relation to others of the same age group. Chronological age (choice B) is a person's actual age in years. Functional age (choice C) refers to how well a person is able to perform various activities compared to their chronological age.
