Study Notes

Psychology History

Psychology originates from the words "Psykhe" and "logia," translating to "study of the soul/spirit."
Early psychology grappled with the question of how to scientifically study the intangible soul.
Modern psychology focuses on the study of the mind and behavior.

Hippocrates (460 BCE)

Hippocrates introduced the theory of humorism, suggesting the concentration of four bodily fluids influences health.
These four fluids (blood, phlegm, yellow bile, black bile) corresponded to the four elements (fire, earth, air, water).
An imbalance in the humors caused illness.

Galen (129 CE)

Galen built upon Hippocrates' theories, clarifying the relationship between humors and temperament.
Galen posited that each person had a unique mix of the four humors, influencing their personality.

Rene Descartes (1586)

Descartes proposed substance dualism, arguing that minds and bodies are distinct and different.
Minds are immaterial and think, while bodies are physical.
His philosophy had a heavy influence from religion.

Emergence of Psychology

The 1800s saw psychology emerge as a distinct field.
Increasing scientific understanding led to attempts to study the mind scientifically.
Figures like Steven Blankaart explored the relationships between mind and body.

Wilhelm Wundt

Wundt established the first psychology laboratory in 1879.
He pioneered introspection as a method for studying conscious experience.
His focus on the structures of conscious experience led to structuralism.

Sigmund Freud

Freud emphasized the role of the unconscious mind.
He believed that mental disorders stem from unconscious conflicts.
His psychoanalysis theory was influential but has also been criticized.

Occam's Razor

Occam's Razor is a principle of parsimony.
It suggests choosing the simplest explanation supported by evidence.

Humans vs Animals

Early 20th-century views were hesitant to attribute mental characteristics to animals.
The capacity for thought was considered a unique human trait.
Research suggests mental processes aren't unique to humans, but rather evolved for survival.

John B. Watson

Watson, a prominent psychologist, emphasized behavior.
He rejected introspection, focusing instead on observable behaviors.
He believed that environment plays a significant role in shaping behavior.

Behaviorism

Behaviorism is a theoretical orientation that focuses on observable behaviors.
Behaviorists like Skinner investigated how associations, reinforcement, and punishment shape behavior.

Competing Perspectives

Humanism opposed behaviorism, emphasizing human experience and subjectivity.
Cognitivism arose, focusing on mental processes.
These approaches offer various perspectives on understanding the human condition.

Science in Psychology

The scientific method provides a systematic approach to testing theories.

The Problem With "Common Sense"

Common sense is a useful starting point for questioning but it may not always be accurate.
People can hold conflicting beliefs at once.

Standard Deviation and Variance

Standard deviation measures data dispersion.
It's crucial for understanding data distribution within a population or sample.

Measuring Variables

Operational definitions allow for consistent data measurement in studies.
The mode, median, and mean are central tendency measurements.

Data Spread (Variability)

Understanding data spread is necessary for accurate interpretation.

Hypotheses, Theories, Laws

A theory provides comprehensive explanations of observations based on gathered evidence.

Research Methods

Researchers often conduct descriptive studies to explore phenomena.
Case studies offer detailed examinations of individuals but may lack generalizability.
Surveys yield data from larger groups but may suffer from response bias.
Correlational studies examine relationships between variables.
Experiments allow researchers to determine cause-and-effect relationships.

Evaluating Data

Data reliability ensures consistent and repeatable measurements.
Validity assesses the accuracy of a measuring instrument in measuring what it intends to measure.

Topic 3: Research Methods

The "Importance of Choosing the Right Method" details how the best methods will deliver the most appropriate results.
Objective evaluation is needed to assess the impact of various methods.
Anecdotal evidence is insufficient to determine causes or suggest methods.
Various types of studies (descriptive, case studies, surveys, correlational, and experimental) are discussed with their strengths and weaknesses.

Topic 4: Research Ethics

Research ethics are crucial for protecting research subjects.
The need for ethical research is heightened when examining humans and animals.
Ethical boards and committees assess the safety of participants and animals involved in research.
Key ethical considerations are informed consent, the avoidance of deception, minimization of harm to participants, and anonymity/confidentiality.

Topic 4: Research Ethics - Continued

The replacement, reduction, and refinement approach (3Rs) help guide how experiments are carried out in animal research.
The Nuremberg Code is an important ethical framework for research.
