environmental factors that influence behavior.
Cognitive approach: An approach to psychology that examines mental processes such as
thinking, problem-solving, and memory.
Humanistic approach: An approach to psychology that emphasizes the potential for personal

Chapter 2: Psychological Research
, This chapter focuses on the methods used in psychological research, including descriptive research,
correlational research, and experimental research. It also covers the ethical principles and challenges
involved in conducting research with human and animal participants.
Key points:
1. Descriptive research methods, such as naturalistic observation and case studies, are used to
describe behavior and mental processes.
2. Correlational research methods are used to examine relationships between variables, but do not
establish causation.
3. Experimental research methods involve the manipulation of an independent variable to observe
its effects on a dependent variable, and can establish causation.
4. Ethical principles in psychological research include informed consent, debriefing, confidentiality,
and the avoidance of harm to participants.
5. Challenges in conducting research with human participants include issues of diversity,
participant demand characteristics, and the placebo effect.
6. Challenges in conducting research with animal participants include ethical considerations, the
use of appropriate species, and minimizing harm to animals.
Important definitions:
Descriptive research methods: Research methods used to describe behavior and mental
processes.
Correlational research methods: Research methods used to examine relationships between
variables, but do not establish causation.
Experimental research methods: Research methods involving the manipulation of an
independent variable to observe its effects on a dependent variable, and can establish causation.
Informed consent: A principle of ethical research that requires participants to be fully informed
about the nature of the research and its potential risks and benefits before agreeing to
participate.
Debriefing: A principle of ethical research that requires participants to be fully informed about
the nature of the research and its findings after the study is completed.
Diversity: The range of different backgrounds and experiences among research participants.
Participant demand characteristics: The tendency of participants to try to guess what the
researcher is studying and to act accordingly.
Placebo effect: The tendency of participants to experience a change in behavior or mental
processes due to their belief that a treatment or intervention is effective.
Ethical considerations: The principles and guidelines that govern the treatment of human and
animal participants in psychological research.
Main ideas:
This chapter provides an overview of the methods used in psychological research, including descriptive
research, correlational research, and experimental research. The chapter emphasizes the importance of
ethical principles in research and the challenges involved in conducting studies with human and animal
participants. By providing examples of research studies and the methods used, the chapter helps
students understand how psychological research is conducted and how results are interpreted.
