Introduction to Psychology

• Psychology is the scientific study of the mind and behavior.
• It involves the study of conscious and unconscious phenomena, as well as feeling and thought.
• It is an academic discipline and applied science which seeks to understand individuals and groups by establishing general principles and researching specific cases.

Types of Psychology

• Abnormal psychology studies unusual patterns of behaviour, emotion and thought, which may or may not be understood as precipitating a mental disorder.
• Behavioral psychology is a learning theory based on the idea that all behaviors are acquired through conditioning.
• Biopsychology examines the role of biological processes and genetics on human behavior.
• Cognitive psychology is the study of mental processes such as attention, language use, memory, perception, problem solving, and creativity.
• Comparative psychology is the scientific study of the behavior and mental processes of non-human animals, especially as these relate to the phylogenetic history, adaptive significance, and development of behavior.
• Counseling psychology focuses on providing therapeutic treatments to clients who experience a wide variety of symptoms.
• Cross-cultural psychology is a branch of psychology that looks at how cultural factors influence human behavior.
• Developmental psychology is the scientific study of how and why human beings change over the course of their life.
• Educational psychology is the study of how people learn, including teaching methods, instructional processes, and individual differences in learning.
• Experimental psychology employs scientific methods to study the mind and behavior.
• Forensic psychology involves applying psychology to the field of criminal investigation and law.
• Health psychology focuses on how biology, psychology, behavior, and social factors influence health and illness.
• Personality psychology studies the patterns of thoughts, feelings, and behavior that make a person unique.
• Social psychology uses scientific methods to study how people's thoughts, feelings, and behaviors are influenced by the actual, imagined, or implied presence of others.

Ethics

• Ethics refers to the correct rules of conduct necessary when carrying out research.
• Researchers have a moral responsibility to protect research participants from harm.
• Informed consent is a vital ethical consideration, ensuring potential participants are fully aware of the research's purpose, procedures, and potential risks before agreeing to participate.
• Participants should be fully aware of the purposes of the research and should explicitly and freely agree to participate.
• Deception should be avoided unless it is necessary for the research and justified by its potential benefits.
• Debriefing involves informing participants about the true nature of the study after it has been completed, especially if deception was used.
• Confidentiality ensures that the data collected from participants is kept private and not disclosed without their permission.
• Researchers should minimize any potential risks to participants' physical or psychological well-being.
• Institutional Review Boards (IRBs) review research proposals to ensure ethical standards are met.
• Researchers should avoid conflicts of interest that could compromise the integrity of the research.
• Researchers should accurately report their findings and avoid falsifying or manipulating data.
• Special considerations are necessary when conducting research with vulnerable populations, such as children or individuals with cognitive impairments.
• Cultural sensitivity is important to ensure research is conducted in a way that respects the values and beliefs of different cultures.

Scientific Methods

• The scientific method is a systematic approach used to acquire knowledge and understand the world.
• It involves formulating a question, developing a hypothesis, designing a study, collecting data, analyzing results, and drawing conclusions.
• Observation involves carefully watching and recording behaviors or phenomena.
• A hypothesis is a testable statement about the relationship between variables.
• Experiments involve manipulating one or more variables to determine their effect on another variable.
• Surveys involve collecting data from a sample of individuals through questionnaires or interviews.
• Case studies involve in-depth investigations of a single individual, group, or event.
• Correlational studies examine the relationship between two or more variables without manipulating them.
• Data analysis involves using statistical techniques to summarize and interpret the data collected.
• Conclusions are drawn based on the results of the data analysis, and they are used to support or refute the hypothesis.
• Replication involves repeating a study to see if the results are consistent.
• The scientific method helps ensure that research is objective, systematic, and reliable.
• It helps to minimize bias and errors in research findings.
• Peer review is a critical part of the scientific method, where experts in the field evaluate research before it is published.
• Theories are developed based on accumulated evidence from multiple studies.
• The scientific method is an iterative process, where new findings build upon previous research.

Types of Research

• Qualitative Research explores and examines opinions to understand trends in thoughts and opinions, dive deeper into the problem.
• Quantitative Research emphasizes objective measurements and the statistical, mathematical, or numerical analysis of data collected through polls, questionnaires, and surveys, or by manipulating pre-existing statistical data using computational techniques.
• Descriptive research describes the characteristics of a population or phenomenon being studied, focusing on the what, when, where, and how of a topic.
• Correlational research examines the relationship between two or more variables, without manipulating them, to determine if they are associated.
• Experimental research involves manipulating one or more variables to determine their effect on another variable, allowing researchers to establish cause-and-effect relationships.
• Longitudinal research involves studying the same group of individuals over an extended period of time, to observe changes and developments.
• Cross-sectional research involves collecting data from a diverse population at a single point in time.
• Survey research involves collecting data from a sample of individuals through questionnaires or interviews.
• Case study research involves an in-depth investigation of a single individual, group, or event.
• Meta-analysis involves combining the results of multiple studies to draw overall conclusions.
• Basic research aims to expand knowledge and understanding of fundamental principles.
• Applied research aims to solve practical problems and improve real-world outcomes.
