Study Notes

Scientific Research as a Critical Tool

Scientific research is crucial for understanding the complex world.
Without it, we rely on intuition, authority, and luck, potentially leading to inaccurate conclusions.
History shows examples of incorrect assumptions, like the geocentric model or the idea that mental illness is caused by possession.
Scientific research uses evidence to support claims, giving us an objective understanding of ourselves and the world.

The Goal of All Scientists

All scientists aim to understand the world.
Psychologists are interested in behavior, and the cognitive and physiological processes behind it.
Scientific research is based on empirical evidence, observable and tangible data.

Use of Research Information

Access to information is readily available, but it is important to assess the reliability and validity of information, especially online.
Critical thinking involves examining different perspectives: expertise, motives, evidence, and opinions of other researchers.
Decisions based on research have significant consequences in personal lives and public policy.

Educational Impact of Technology

Technology's impact on learning is a topic of ongoing research.
Some studies show an increase in student engagement and better test scores.
Other studies indicate negative impacts on sleep, communication, and time management skills.
There is no clear consensus on technology's effects on mental health, as further research is required.

Notable Researchers

Margaret Floy Washburn was the first woman to earn a PhD in psychology, focusing on animal behavior.
Mary Whiton Calkins was a prominent early American psychologist and pioneer in experimental psychology. She focused on memory and established one of the first experimental labs.
Francis Sumner: the first African American to achieve a PhD in psychology.
Inez Beverly Prosser: became the first African American woman to earn a PhD in psychology and focused on the effect of education in segregated versus integrated schools.

The Process of Scientific Research

Scientific knowledge advances using the scientific method.
This is a cyclical process of testing ideas against real-world observations.
It involves two main types of reasoning: deductive (testing ideas against observed data) and inductive (creating new ideas from observations).

The Scientific Method

The scientific method involves deriving hypotheses from theories and testing them.
If the results support the theory, the theory is supported.
If the results do not support the theory, the theory should be modified and new hypotheses are generated.
Hypotheses must be falsifiable (capable of being proven wrong).

Clinical or Case Studies

Case studies examine individuals or small groups in depth.
They can provide valuable insights into specific cases and unique phenomena.
However, it is difficult to generalize findings to the wider population.
Case studies often involve observing exceptional cases, such as conjoined twins, that provide unique data.

Naturalistic Observation

Naturalistic observation involves studying behavior in naturally occurring settings.
Observers try to remain inconspicuous to avoid influencing the behavior of the participants they are observing.
Ethical considerations influence the need for inconspicuous observation so as not to bias participants.

Archival Research

Archival research analyses existing records (historical data) to look for patterns and relationships.
Research allows researchers to extract data and information from archival records, saving time and resources.
Researchers can analyse archival research to find correlations between variables that might otherwise be difficult to explore.

Longitudinal and Cross-Sectional Research

Longitudinal research involves repeated measurements of the same group of participants over a long time period
Cross-sectional research involves comparing different groups of people at different points in time.

Correlation Research

Correlation research measures the relationship between variables.
A correlation coefficient (r) indicates the strength and direction of a relationship (ranging from -1 to +1).
A positive correlation means both variables increase or decrease together; a negative correlation means one variable increases as the other decreases.

Illusory Correlations

Illusory correlation involves believing that a relationship exists when no such relationship exists, especially when observations are unsystematic.

Experimental Research

Experiments establish cause-and-effect relationships.
The experimental group receives the treatment (independent variable), and the control group does not.
Random assignment helps ensure the groups are similar, and thus any subsequent differences are due to the experimental manipulation.
Operational definition defines how variables are measured.

Issues in Experiments

Ethical constraints can limit experimental research.
Random assignment, manipulation of variables, and operational definitions.
Researchers must avoid bias (experimenter bias)

Reporting Research

Peer-reviewed journal articles are the primary way researchers share their findings.
Scientists critically evaluate each other’s work to ensure it is methodologically sound and contributes new knowledge.

Research Involving Participants and Animals

Participants must be adequately informed about the study to ensure their autonomy and well-being.
Informed consent forms must describe the procedures and potential risks.
Animal research must follow guidelines and ethical protocols. IACUC committees oversee animal research.

Reliability and Validity

Reliability refers to the consistency of results.
Validity refers to the accuracy of results.
Reliability does not ensure validity.
