Development
This term describes changes that happen as a person grows older.
What is development?
This type of memory holds information for a very short time.
What is short-term memory (STM)?
This refers to how consistent a result is when repeated.
What is reliability?
This sampling method uses chance to select participants.
What is random sampling?
This is a testable statement predicting the outcome of a study.
What is a hypothesis?
This type of development involves thinking, learning, and memory.
What is cognitive development?
This memory store has a potentially unlimited capacity.
What is long-term memory (LTM)?
This refers to whether a study measures what it intends to measure.
What is validity?
This method uses people who are easiest to access.
What is opportunity sampling?
This type of hypothesis predicts a specific direction of results.
What is a directional hypothesis?
This psychologist is famous for stages of cognitive development.
Who is Piaget?
This is the process of converting information into a memory.
What is encoding?
This type of reliability checks consistency over time.
What is test-retest reliability?
This sampling method divides people into groups and selects from each.
What is stratified sampling?
This hypothesis predicts a difference but not the direction.
What is a non-directional hypothesis?
The stage where children begin to think logically about concrete events.
What is the concrete operational stage?
This model divides memory into sensory, short-term, and long-term stores.
What is the multi-store model?
When results can be applied to real-life situations, this type of validity is high.
What is ecological validity?
This method involves participants selecting themselves for the study.
What is volunteer sampling?
This hypothesis states there will be no effect or difference.
What is the null hypothesis?
This is the process where children adjust their thinking to fit new information.
What is accommodation?
This type of rehearsal involves thinking about meaning to remember better.
What is elaborative rehearsal?
This is when different researchers get similar results using the same method.
What is inter-rater reliability?
This is one disadvantage of volunteer sampling.
What is volunteer bias?
This must be clearly defined so it can be measured in a study.
What are operationalised variables?
