In ecological systems theory, how does Toby's move just before entering fourth grade represent a significant change in his life?
- A. Microsystem
- B. Mesosystem
- C. Exosystem
- D. Chronosystem
Correct Answer: D
Rationale: In ecological systems theory, the chronosystem refers to the dimension of time and how events and transitions over time can influence an individual's development. Toby's move just before entering fourth grade represents a significant change in his life that falls under the chronosystem. The microsystem involves the immediate environments and relationships that directly influence an individual, the mesosystem relates to connections between these environments, and the exosystem includes external settings that indirectly influence the individual, such as parents' workplaces. Therefore, Toby's move best exemplifies a change in the chronosystem due to the temporal influence on his development.

In a cross-sectional design, researchers study __________.
- A. the same group of participants repeatedly at different ages
- B. groups of participants differing in age at the same point in time
- C. groups of participants of the same age in different years
- D. participants of the same age at the same point in time
Correct Answer: B
Rationale: In a cross-sectional design, researchers study groups of participants differing in age at the same point in time. This design allows researchers to compare different age groups simultaneously, providing valuable insight into age-related differences without the need to track the same group over time. Choice A is incorrect because it describes a longitudinal design where the same group is followed over time. Choice C is incorrect as it involves different groups of the same age studied at different times. Choice D is incorrect as it does not capture the essence of a cross-sectional design, which involves studying groups of different ages at the same point in time.
Despite growing up in a rundown neighborhood, having divorced parents, and rarely seeing her father, Betty is a successful, happy, and healthy adult. Betty's ability to adapt effectively in the face of threats to development is known as __________.
- A. assimilation
- B. resilience
- C. age-graded development
- D. multidimensional development
Correct Answer: B
Rationale: Betty's ability to adapt effectively despite facing challenges during her childhood such as growing up in a rundown neighborhood, having divorced parents, and rarely seeing her father demonstrates resilience. Resilience refers to the capacity to achieve positive outcomes despite adverse circumstances. Betty's successful, happy, and healthy adulthood showcases her resilience in navigating and overcoming the threats to her development.
Choice A, assimilation, does not fit the context of adapting effectively to adverse circumstances. Assimilation is a cognitive process related to incorporating new information into existing schemas. Choice C, age-graded development, refers to typical developmental changes that occur in a culture at a particular age. Choice D, multidimensional development, encompasses the idea that development is influenced by multiple factors across various dimensions, which is not directly related to Betty's ability to adapt effectively despite facing challenges.
Observations of imprinting led to which major concept in human development?
- A. adaptation
- B. equilibrium
- C. the critical period
- D. classical conditioning
Correct Answer: C
Rationale: Observations of imprinting in animals, such as ducklings following the first moving object they see after hatching, led to the major concept of the critical period in human development. The critical period is a specific time frame during which an organism must experience certain stimuli to develop properly. This concept has been influential in understanding various aspects of human development, such as language acquisition and social attachment. Choices A, B, and D are incorrect. Adaptation refers to adjusting to the environment, equilibrium is about balance in cognitive processes, and classical conditioning is a learning process associated with behaviorism, none of which directly relate to the concept derived from imprinting observations.
Baby Azeez's limb movements are gentle. He stirs occasionally, and facial grimacing occurs. Although his eyelids are closed, occasional rapid eye movements can be seen beneath them. Azeez is most likely in which state?
- A. regular sleep
- B. drowsiness
- C. irregular sleep
- D. quiet alertness
Correct Answer: C
Rationale: The description of Baby Azeez's behavior matches the characteristics of irregular sleep in a newborn. During irregular sleep, limb movements are gentle, occasional facial grimacing occurs, and rapid eye movements can be seen beneath closed eyelids. This state is also known as active sleep and is associated with dreaming in newborns. Choice A, regular sleep, is incorrect as the described behaviors are not typical of this state. Choice B, drowsiness, does not match the active movements and facial grimacing observed in Azeez. Choice D, quiet alertness, is also incorrect as it does not align with the described behaviors of limb movements, facial grimacing, and rapid eye movements.
An experimental design __________.
- A. allows researchers to gather information in natural life circumstances without altering the participants' experiences
- B. looks at relationships between participants' characteristics and their behavior or development
- C. permits inferences about cause and effect because researchers evenhandedly assign people to treatment conditions
- D. has one major limitation: researchers cannot infer cause and effect
Correct Answer: C
Rationale: An experimental design permits inferences about cause and effect because researchers evenhandedly assign people to treatment conditions. This means that researchers can manipulate certain variables and observe the effects on participants, allowing them to determine causation between variables. This is a key strength of experimental research designs. Choices A, B, and D are incorrect because they do not accurately describe the primary purpose or strength of experimental designs. Experimental designs do not focus on gathering information in natural life circumstances (A), looking at relationships between characteristics and behavior (B), or have the limitation of not being able to infer cause and effect (D).
