Study Notes
Theories
- Theories are formed from hypotheses that are repeatedly tested and confirmed.
- Theories can be supported or disproven by new evidence.
- They are not the same as opinions or beliefs.
- They are testable and logical.
- All theories are not equally plausible.
- A good theory can explain previous research and lead to more testable hypotheses.
- The quality of a theory is not related to the number of people that believe it.
The Biopsychosocial Model
- Explains behaviors as a product of biological, psychological, and sociocultural factors.
- Biological influences include brain structures and chemicals, hormones, and external substances.
- Psychological influences involve memory, emotions, and personality, shaping our thoughts.
- Social factors like family, peers, ethnicity, and culture influence behavior.
- All of these can affect behavior simultaneously and can interact with each other.
Research Methodology
- Random sampling is preferred for generalizability.
- A random sample is representative of the population.
- Convenience samples, such as university students, are readily available but may not be representative.
- Ecological validity ensures results can be applied to the natural environment.
- It is important to avoid overgeneralizing from convenience samples as they may not represent all populations.
Sources of Bias
- Researcher bias can occur when the experimenter treats participants differently.
- Subject bias occurs when participants try to figure out the study or respond in a way that confirms the hypothesis.
- Full debriefing is necessary after research to explain the study and any deception.
Anonymity and Confidentiality
- Anonymity means data collected during research cannot be linked to individuals.
- Confidentiality means researchers cannot share data that could be connected to individuals, and records are kept secure.
Ethics for Animal-Based Research
- Ensures ethical treatment of animals in research.
- Emphasis is placed on basic care, minimization of pain and discomfort, and justification for any necessary discomfort.
- The same standards apply if animals are sacrificed for research.
Cells and Neurotransmitters
- Neurons communicate through electrochemical reactions.
- The axon transports this information from the cell body to the axon terminals.
- Axon terminals contain neurotransmitters, chemical messengers for neuron communication.
- Different neurotransmitters have various functions.
- Sensory neurons receive information and transmit it to the brain.
- Motor neurons send messages from the brain to muscles.
- Interneurons facilitate communication between neurons.
- The structure of a neuron is related to its function.
Glial Cells
- Support neurons and are involved in immune responses, waste removal, and synchronizing neuron activity.
- Neurons have a resting potential, a stable state of negative charge inside compared to a positive charge outside.
- This is maintained by an electrostatic gradient and a concentration gradient of ions.
- When a neuron is stimulated, ion channels open, and sodium ions flow into the cell.
- The influx of positive ions changes the cell's charge and initiates an action potential.
- The action potential travels down the axon and changes the charge from negative to positive.
