Study Notes
Understanding Theories & Hypotheses
- Theories provide a broad explanation for a phenomenon, encompassing human behavior.
- Hypotheses are specific predictions derived from theories, used to test particular aspects.
- Theories evolve through repeated testing and confirmation of hypotheses.
- A supported hypothesis strengthens the credibility of the corresponding theory.
Evaluating Theories
- Theories differ from opinions and beliefs; they require evidence and logical reasoning.
- Not all theories hold equal weight, and multiple theories can coexist regarding complex topics like depression.
- A strong theory accurately explains past research and generates new hypotheses.
- The popularity or acceptance of a theory does not determine its quality; evidence matters more.
Biopsychosocial Model
- This model explains behavior as an interplay of biological, psychological, and sociocultural factors.
- Biological influences include brain structures, chemicals, hormones, and external substances.
- Psychological influences encompass memories, emotions, and personality traits.
- Sociocultural influences encompass family dynamics, peers, ethnicity, and cultural norms.
Scientific Literacy & Critical Thinking
- Scientific literacy involves understanding, analyzing, and applying scientific information.
- Critical thinking encourages curiosity and skepticism when evaluating information and personal beliefs.
- Essential skills for developing critical thinking:
- Cultivating curiosity.
- Examining evidence and its source.
- Identifying assumptions and biases.
- Avoiding overly emotional reasoning.
- Tolerating ambiguity and multiple perspectives.
- Considering alternate viewpoints.
The Principle of Parsimony
- The simplest explanation for a phenomenon is generally preferred over more complex ones.
Origins of Psychology as a Science
- Empiricism emphasizes knowledge gained through experience and careful observation, not common assumptions.
- Determinism proposes that all events are governed by cause-and-effect relationships.
Historical Figures & Concepts
-
Galen's theory of four temperaments linked personality to bodily fluids:
- Sanguine (blood): impulsive, pleasure-seeking, charismatic.
- Choleric (yellow bile): ambitious, energetic, potentially aggressive.
- Melancholic (black bile): independent, perfectionist, introverted.
- Phlegmatic (phlegm): quiet, relaxed, content with life.
-
Zeitgeist refers to the prevailing beliefs and attitudes of a specific culture and time period.
-
Materialism asserts that humans and living beings are purely physical matter.
-
Dualism posits the existence of non-material aspects of humans, like a mind or soul separate from the body.
Key Contributions in Early Psychology
- Psychophysics studies the connection between the physical world and its mental representation.
- Fechner's weight experiment illustrated the principles of psychophysics.
- Titchener focused on identifying the basic elements of thought processes.
Darwin and the Impact of Evolution
- Charles Darwin's theory of evolution by natural selection emphasizes the importance of inherited traits that enhance survival and reproduction.
- Darwin's work extended to understanding behavior; he argued that behaviors also evolve through natural selection.
Emergence of Psychological Fields
- Clinical psychology specializes in diagnosing and treating mental disorders.
- Localization of brain function suggests that specific brain areas control particular mental abilities and personality traits.
- Phrenology (mid-1800s) incorrectly linked skull bumps to mental traits, but contributed to the localization concept.
- Humanistic psychology emphasizes individual uniqueness, freedom, rational thought, and the distinct nature of humans compared to other animals.
Hebb's Law and Neural Plasticity
- Hebb's Law states that repeated stimulation between neurons strengthens their connection.
- This principle supports the idea that neuronal connections can be modified through experience.
Cross-Cultural Psychology
- Compares individual and group behaviors across cultures.
- Helps understand the societal influence on behaviors, beliefs, and values.
Cognitive Neuroscience
- Integrates cognitive psychology and biopsychology.
- Investigates the neural processes underlying mental functions, such as memory, attention, and language.
Positive Psychology
- Promotes well-being by fostering self-acceptance and enhancing social relationships.
- Aims to help individuals thrive and flourish through positive experiences and strengths.
