1. In the 5th substage of sensorimotor development, what does Piaget refer to as 'experimentation,' where the infant tries out new ways of playing with or manipulating objects?

A. Short-term memory
B. Working memory
C. Core memories
D. Long-term memory

Correct answer: D

Rationale: The correct answer is D, 'Long-term memory.' In the 5th substage of sensorimotor development, Piaget refers to 'experimentation' as tertiary circular reactions, where the infant tries out new ways of playing with or manipulating objects. This stage involves exploring and testing different ways of interacting with the world to understand cause and effect relationships. Choices A, B, and C are incorrect as they do not align with Piaget's concept of tertiary circular reactions and experimentation in the sensorimotor stage of development.

2. Which of the following characteristics best describes differences between bulimia nervosa and anorexia nervosa?

A. Individuals with anorexia nervosa do not have as severe health risks as individuals with bulimia nervosa have.
B. Individuals with bulimia nervosa may have a normal body weight.
C. Individuals with anorexia nervosa have been known to binge like those with bulimia nervosa on occasion.
D. Only those with bulimia nervosa display compensatory behaviors.

Correct answer: B

Rationale: The correct answer is B. Individuals with bulimia nervosa may maintain a normal body weight, while anorexia nervosa is often associated with severe underweight. Choice A is incorrect because individuals with anorexia nervosa actually face severe health risks due to malnutrition, electrolyte imbalances, and other complications. Choice C is incorrect as anorexia nervosa is characterized by restriction of food intake rather than binge eating. Choice D is incorrect as individuals with anorexia nervosa can also display compensatory behaviors such as excessive exercise or fasting.

3. Scientific research has demonstrated the __________ parenting style is most likely to lead to healthy psychological development in children.

A. Authoritarian
B. Permissive
C. Authoritative
D. Neglectful

Correct answer: C

Rationale: Scientific research has demonstrated that the authoritative parenting style is most likely to lead to healthy psychological development in children. Authoritative parents are responsive to their children's emotional needs, set clear boundaries, and encourage independence. This balance fosters a positive environment for children to thrive emotionally and psychologically. Authoritarian parenting (choice A) focuses on strict rules without much warmth, which can lead to obedience but may hinder emotional development. Permissive parenting (choice B) lacks structure and rules, potentially resulting in children feeling insecure. Neglectful parenting (choice D) is characterized by a lack of responsiveness and involvement, leading to various negative outcomes for the child's development.

4. How do early life experiences shape brain development and behavior?

A. Early life experiences have no impact on brain development.
B. Early life experiences are crucial in shaping brain development and later behavior.
C. Early life experiences are not significant in brain development.
D. Early life experiences are easily overcome by adulthood.

Correct answer: B

Rationale: Early life experiences are crucial in shaping brain development and later behavior. These experiences play a significant role in laying the foundation for future mental health and behavior. Choice A is incorrect because early life experiences do have a profound impact on brain development. Choice C is incorrect as early life experiences are indeed significant in brain development. Choice D is incorrect as early life experiences can have lasting effects into adulthood.

5. How does the diathesis-stress model explain the onset of mental disorders?

A. Stress alone is sufficient to cause mental disorders.
B. Both genetic vulnerability and environmental stress are needed to trigger a disorder.
C. Only genetic factors cause mental disorders.
D. Environmental stressors alone can cause mental disorders.

Correct answer: B

Rationale: The diathesis-stress model explains that the onset of mental disorders results from the interaction of genetic vulnerability (diathesis) and environmental stress. Choice A is incorrect because stress alone is not sufficient, according to the model. Choice C is incorrect as it oversimplifies by attributing mental disorders solely to genetic factors. Choice D is incorrect because the model emphasizes the joint contribution of genetic predisposition and environmental stress.
