#2
What is the purpose of informed consent in developmental psychology research?
To provide participants with information about the study and obtain their voluntary agreement to participate
ExplanationInformed consent ensures participants are well-informed and willingly agree to take part in developmental psychology research.
#3
Which of the following is an example of a developmental milestone in infancy?
Rolling over from back to stomach
ExplanationRolling over from back to stomach is a significant motor skill achievement, representing a developmental milestone in infancy.
#4
Which of the following is an example of a cross-sectional study?
Comparing different age groups at one point in time
ExplanationCross-sectional studies involve comparing diverse age groups at a single time point to analyze developmental differences.
#5
What is the term for a research design that examines the effects of one or more independent variables on a dependent variable?
Experimental study
ExplanationAn experimental study investigates the impact of independent variables on a dependent variable to establish causal relationships in developmental psychology.
#6
What is the main difference between a correlational study and an experimental study?
Experimental studies involve random assignment, while correlational studies do not.
ExplanationExperimental studies utilize random assignment to groups, enabling causal inference, while correlational studies explore relationships between variables without manipulation.
#7
What is a longitudinal study in developmental psychology?
A study that follows the same group of individuals over an extended period
ExplanationLongitudinal studies track a consistent group of individuals across an extended timeframe, providing insights into developmental changes.
#8
Which research method allows researchers to assess cause-and-effect relationships in developmental psychology?
Experimental design
ExplanationExperimental design enables researchers to establish causal connections between variables in developmental psychology.
#9
What is the term for a sudden understanding of how to solve a problem, which often occurs after a period of frustration?
Insight
ExplanationInsight refers to the sudden comprehension of a problem solution, often arising after a frustrating period of contemplation.
#10
Which theorist proposed the psychosocial stages of development, including stages such as Trust vs. Mistrust and Intimacy vs. Isolation?
Erik Erikson
ExplanationErik Erikson introduced the psychosocial stages, exploring crucial developmental conflicts, such as Trust vs. Mistrust and Intimacy vs. Isolation.
#11
Which of the following is NOT a method of data collection used in developmental psychology research?
MRI scans
ExplanationMRI scans are not a typical method of data collection in developmental psychology research, which often relies on observational, survey, and experimental methods.
#12
What is the term for the phenomenon where individuals of the same age group are similar in certain characteristics or behaviors?
Cohort effects
ExplanationCohort effects refer to similarities among individuals of the same age group in specific characteristics or behaviors, influenced by shared experiences.
#13
What is the purpose of random assignment in experimental research?
To ensure that participants are assigned to groups by chance
ExplanationRandom assignment in experimental research ensures unbiased group allocation, enhancing the validity of study results.
#14
Which of the following is a limitation of cross-sectional studies in developmental psychology?
They are limited in their ability to assess developmental changes over time
ExplanationCross-sectional studies have constraints in evaluating developmental changes over time due to their snapshot-like nature.
#15
What is the term for the tendency to focus on only one aspect of a situation and ignore other important aspects?
Centration
ExplanationCentration refers to the inclination to concentrate on a single aspect of a situation while neglecting other relevant elements.
#16
According to Piaget's theory of cognitive development, which stage occurs during early childhood and is characterized by the ability to think symbolically, but with limited logical reasoning?
Preoperational stage
ExplanationThe preoperational stage in Piaget's theory involves symbolic thinking but limited logical reasoning, typically occurring in early childhood.
#17
Which of the following best describes the concept of scaffolding in Vygotsky's sociocultural theory?
Providing support and guidance to help a child learn a new skill
ExplanationScaffolding in Vygotsky's theory involves providing support and guidance to assist a child in acquiring new skills, fostering cognitive development.
#18
What is the term for the tendency to search for information that confirms one's preconceptions while ignoring contradictory evidence?
Confirmation bias
ExplanationConfirmation bias is the inclination to seek information validating preexisting beliefs while disregarding evidence contradicting those beliefs.
