Human Growth and Development Exam 1
1. What are the most obvious organized patterns of behavior in a newborn baby?
- A. Reflexes
- B. States of arousal
- C. Shrill cries
- D. Sleep patterns
Correct answer: A
Rationale: The correct answer is A: Reflexes. Reflexes are automatic, involuntary responses to specific stimuli and are the most obvious organized patterns of behavior in a newborn baby. Examples of newborn reflexes include sucking, rooting, grasping, and the Moro reflex. These reflexes are crucial for the newborn's survival and overall development. Choice B, states of arousal, refers to different levels of consciousness and responsiveness, not organized behavior patterns. Choice C, shrill cries, is a form of communication and not an organized behavior pattern. Choice D, sleep patterns, while important for newborns, are not the most obvious organized behavior patterns.
2. Researchers randomly assigned adolescents to either a single-grade classroom or a mixed-age classroom. This is an example of a __________.
- A. naturalistic observation
- B. case study
- C. natural experiment
- D. field experiment
Correct answer: D
Rationale: In this scenario, the researchers randomly assigned adolescents to either a single-grade classroom or a mixed-age classroom, which is an example of a field experiment. A field experiment involves manipulating independent variables in a natural setting to observe the effects on participants. This design allows for more control over variables compared to naturalistic observation, case studies, or natural experiments. Naturalistic observation involves observing subjects in their natural environment without manipulating any variables. A case study focuses on in-depth analysis of a single individual or a small group. A natural experiment involves observing naturally occurring events without intervention or manipulation by the researcher.
3. What is one challenge associated with longitudinal research?
- A. It does not allow for inferences about cause-and-effect relationships.
- B. Participants may relocate or drop out of the study.
- C. Findings may not be applicable to real-world scenarios.
- D. It does not allow for the examination of individual developmental patterns.
Correct answer: B
Rationale: One challenge associated with longitudinal research is that participants may relocate or drop out of the study over time. This can result in missing data and potential biases in the findings, impacting the study's overall validity and reliability. Furthermore, it can present difficulties for researchers in accurately monitoring and analyzing changes in individuals over an extended period. Options A, C, and D are incorrect because longitudinal research can indeed allow for inferences about cause-and-effect relationships, findings can be generalized to the real world with appropriate design and sampling, and it is suitable for studying individual developmental patterns.
4. Spatial skills __________.
- A. increase exponentially in early childhood
- B. support children's improved executive function
- C. develop gradually over childhood and adolescence
- D. are typically housed in the left hemisphere
Correct answer: C
Rationale: Spatial skills develop gradually over childhood and adolescence, reflecting the increasing complexity of these abilities. Choice A is incorrect because spatial skills do not increase exponentially in early childhood but rather develop steadily. Choice B is incorrect as spatial skills are not directly linked to executive function. Choice D is incorrect because spatial skills are not typically housed in a specific hemisphere but involve a network of brain regions.
5. Dr. George predicted that positive reinforcement would increase prosocial behavior in preschoolers. Dr. George's prediction is an example of a __________.
- A. theory
- B. research question
- C. hypothesis
- D. research design
Correct answer: C
Rationale: Dr. George's prediction that positive reinforcement would increase prosocial behavior in preschoolers is an example of a hypothesis. A hypothesis is a specific, testable prediction about the relationship between variables based on existing knowledge or theories. In this case, Dr. George is making a prediction about the effect of positive reinforcement on prosocial behavior, which can be tested through research. Choice A, 'theory,' is incorrect because a theory is a broader explanation that integrates a range of findings and observations. Choice B, 'research question,' is incorrect as it refers to an inquiry that asks about the relationship between variables but lacks the specificity and testability of a hypothesis. Choice D, 'research design,' is incorrect as it pertains to the overall strategy or plan for conducting a research study, not the specific prediction Dr. George made.
