cognitive Flashcards
Cross-sectional design
Comparing two or more groups on a particular variable at a specific time. The opposite is a longitudinal design where the researcher measures a change in an individual over time.
Longitudinal study
research over a period of time using observations, interviews, or psychometric testing. (Similar to a repeated measures design in an experiment).
Prospective research
A study that attempts to find a correlation between two variables by collecting data early in the life of participants and then continuing to test them over a period of time to measure change and development.
Retrospective research
A study of an individual after an important change or development. For example, the study of a person after a stroke. This requires the research to “reconstruct” the life of the individual prior to the event.
Verbal protocols
A type of interview where the researcher has the participant “think aloud” while solving a problem.
Declarative memory
“knowing what“
is the memory of facts and events and refers to those memories that can be consciously recalled. There are two subsets of declarative memory
Episodic memory
the memory of specific events that have occurred at a given time and in a given place.
memoriesof events
Procedural memory
“knowing how”
is the unconscious memory of skills and how to do things.
how to perform tasks
Semantic memory
general knowledge of facts and people, for example, concepts and schemas and it is not linked to time and place.
facts
Transactive memory
a mechanism through which groups collectively encode, store, and retrieve knowledge
Anchoring bias
an individual relies too heavily on an initial piece of information offered (known as the “anchor”) when making decisions.
Availability heuristic
a mental shortcut that relies on immediate examples that come to a given person’s mind when making a decision, rather than considering all information.
Heuristics - the process by which humans use mental shortcuts to arrive at decisions. Heuristics are simple strategies that are used to quickly form judgments, make decisions, and find solutions to complex problems.
Central Executive
The part of Baddeley & Hitch’s Working Memory Model responsible for the control and regulation of cognitive processes. It binds information from a number of sources into a coherent “episode”, coordinates the sub-systems, shifts between tasks, and handles selective attention and inhibition.
control center - manages and manipulates information
Cognitive bias
a systematic error in thinking that impacts one’s choices and judgments.
A systematic error, often subconsious, automatic, makes quick decesions
Cognitive biases are systematic cognitive dispositions or inclinations in human thinking and reasoning that often do not comply with the tenets of logic, probability reasoning, and plausibility. These intuitive and subconscious tendencies are at the basis of human judgment, decision making, and the resulting behavior.
Cognitive load
The amount of information that working memory can hold at one time
