Study Notes
Statistics in Psychology
- Neuman-Keuls test is a statistical test used in psychology.
Structure of a Neuron
- A vertebrate motor neuron consists of:
- Axon
- Soma
- Myelin sheath (but not cortisol)
Measures of Dispersion
- Variance is a measure of dispersion.
- Range is a measure of dispersion.
Punishment and Reinforcement
- Having crayons taken away is a form of punishment by removal.
- Being made to wash off the drawing is a form of punishment by application.
Memory
- Visual sensory memory lasts for a fraction of a second.
- Selective attention moves information from short-term memory to long-term memory.
Schedules of Reinforcement
- Fixed ratio schedule: reinforcement is provided after an unpredictable number of responses.
- Fixed interval schedule: varying amount of time passes between two reinforcements.
- Variable ratio schedule: number of responses required for reinforcement is always the same.
- Variable interval schedule: the interval of time that must pass before reinforcement is always the same.
Retrieval of Memories
- Bits and pieces of information are gathered from various sources and put back together in a process called constructive processing.
Decision Making
- One model of decision making relies on simplifying strategies or rules of thumb based on past experiences, fairness, past events, and aversion to loss.
Cognitive Development (Piaget's Theory)
- During the pre-operational stage (2-7 years), children:
- Focus only on one feature of an object, while ignoring other relevant features.
- Are unable to mentally reverse an action.
- Cannot conserve, reverse their thinking, and classify objects in terms of various characteristics.
Item-Response Theory
- Item-response theory talks about how items should function based on the knowledge of an ability or trait.
- It compares responses to items to determine how well the items function.
Groupthink
- Characteristics of groupthink include:
- Excessive optimism and risk taking.
- Silence being interpreted as consent.
- Members reducing their efforts and performance levels while acting as a part of the group.
