Methods of Studying

IV: Methods of Studying Human Development

The Scientific Method Identify research questions or problem, gather information, summarize information and make decision regarding hypothesis, interpret summarized information
Naturalistic Observation observation in natural, real-world environments
Structured Observation observation in controlled environments
Social Desirability Bias when respondents give answers to questions that they believe will make them look good to others, concealing their true opinions or experiences
Surveys, Questionnaires, Interviews the person under study answers questions about his or her experiences, attitudes, opinions, beliefs, and behavior
Open Ended Interview a trained interviewer uses a conversational style that encourages the participant, or person under study, to expand his or her responses by varying the order of questions, probe, or ask additional questions based on responses
Structured Interview an interviewer poses the same set of questions to each participant in the same way
Methods of Data Collection observation, self-report measures, physiological measures
Electroencephalography (EEG) measures electrical activity patterns produced by the brain via electrodes placed on the scalp; researchers study fluctuations in activity that occur when participants are presented with stimuli or when they sleep
Computerized Tomography (CT) compiles multiple x-rays images to create a 3D image of a person's brain; density of brain structures, bone, brain vasculature, & tissue; illustrate how the thickness of the cortex changes w/ development
Positron Emission Tomography (PET) involves injecting a small dose of radioactive material into the person's bloodstream to monitor the flow of blood; images can illustrate what parts of the brain are active as participant view stimuli and solve problems
Functional Magnetic Resonance Imaging (fMRI) measure brain activity w/ a powerful magnet that uses radio waves and to measure blood oxygen level(more active=higher); researchers able to determine which parts of the brain are active as individuals complete cognitive tasks
Diffusion Tensor Imaging (DTI) uses MRI machine to track how water molecules move in fibers connecting parts of the brain gauges the thickness & density of the brain's connections permitting researchers to measure the brain's white matter & determine changes that occur with development
Case Study an in-depth examination of a single person
Correlational Research describes the strength of the relationship between two or events or characteristics; permits researchers to examine relations among measured characteristics, behaviors, and events
Experimental Research used to test hypotheses about causal relationships
Dependent Variable what is measured in an experiment, can change as the independent variable is manipulated
Independent Variable the factor that is proposed to change the behavior under study
Cross-Sectional Research Designs compares groups of people of different ages at a single point in time ex.) 15-year-olds, 20-year-olds, and 25-year-olds studied in 2020
Longitudinal Design follows the same group of participants over many points in time ex.) 15-year0olds in 2010, 20-year-olds in 2015, 25-year-olds in 2020
Cohort Effect time of birth or generation (not actual chronological age) creates the effect
Sequential Research Designs combines the best features of cross-sectional and longitudinal research by assessing multiple cohorts over time, enabling scientists to make comparisons that disentangle the effects of cohort and age
Informed Consent participants' informed, rational, and voluntary agreement to participate
Child Assent children's agreement to participate; get consent from their parents
Passive Consent default is consent, which requires opting out; procedures typically involve notifying parents about the research and requiring them to reply if they do not want the child to participate
Confidentiality responses will remain confidential and not be disclosed to others
Applied Developmental Science a field of study that examines the lifelong developmental interactions among individuals and their contexts and applies these findings to prevent and intervene in problems and promote positive development
