Summary
Highlights
The video introduces competency number two, focusing on research methods in developmental psychology and ethical considerations. It begins by discussing basic research designs.
This section covers fundamental research designs. A case study is an in-depth investigation of a single individual, group, or situation, providing detailed insights but limiting generalizability. Ethnographic studies involve in-depth cultural analysis through participant observation, helping to understand behaviors and traditions and overcoming cultural biases. Correlational studies examine relationships between variables, identifying positive or negative correlations, but cannot establish cause and effect. An example of ice cream sales and drowning incidents illustrates this lack of causation.
Experiments are controlled procedures to determine cause and effect by manipulating independent variables and measuring dependent variables. This design offers high control but may lack real-world applicability. Developmental designs are introduced, including cross-sectional, longitudinal, and sequential studies. Cross-sectional studies compare different age groups at one point in time, being faster and more economical, but cannot track individual changes. The 'color pink' preference study is cited as an example.
Longitudinal studies collect data from the same individuals repeatedly over a long period, useful for observing developmental changes and reducing cohort effects, but are time-consuming and expensive. Sequential studies combine cross-sectional and longitudinal techniques, offering a comprehensive view of age, cohort effects, and developmental patterns, but require significant time, effort, and funding.
The discussion shifts to ethical considerations, guided by the American Psychological Association (APA) general principles. These principles ensure proper and respectful treatment of clients and participants. The five main principles are Beneficence and Nonmaleficence (doing good and avoiding harm), Fidelity and Responsibility (trust and professional standards), and Integrity (honesty and truthfulness).
The APA principles continue with Justice (fairness and equal access to psychological services, avoiding discrimination based on gender, race, socioeconomic status, or disability) and Respect for People's Rights and Dignity (protecting privacy, confidentiality, and self-determination, especially in diverse cultural contexts).
The video then focuses on the ethical guidelines set by the Psychological Association of the Philippines (PAP), which align with APA principles. These emphasize respect for dignity, competent caring, integrity, and social responsibility.
This section details the critical importance of informed consent in psychological research, especially when involving vulnerable populations such as children, individuals with disabilities, and the elderly. Researchers must obtain consent from legal guardians and assent from participants when possible, ensuring understanding of the study's purpose, risks, and benefits. Documentation, recording ethical issues, and exceptions to full informed consent are also discussed.
The video covers ethical practices related to incentives, warning against excessive rewards that may coerce participation. Deception in research is discussed, permitted only under strict conditions and followed by debriefing. Avoiding plagiarism and properly crediting authors is emphasized. Sharing research data ethically, such as using pseudo names to maintain participant privacy while contributing to scientific knowledge, is also highlighted.
The final ethical consideration addresses cultural bias and ethnocentrism. Researchers must approach cultural differences with openness, respect, and objectivity, avoiding stereotypes and the belief that one's own culture is superior. It's crucial for psychologists to recognize that behaviors and developmental practices vary across cultures and should be understood within their respective cultural contexts.
