Short-term memory (STM) is a component of memory that holds a small amount of information in an active, readily available state for a brief period of time, typically a few seconds to a minute. It's often likened to the brain's "working space," enabling tasks like reasoning and language comprehension. STM's capacity is limited, often thought to be about 7±2 items. Information not rehearsed or processed can quickly be forgotten.| Simply Psychology
The multi-store model of memory, proposed by Atkinson and Shiffrin, explains memory as three separate stores: sensory memory, short-term memory, and long-term memory. Information moves between these stores through attention, rehearsal, and retrieval, highlighting that memory is a linear process involving distinct stages.| Simply Psychology
In research, the independent variable is manipulated to observe its effect, while the dependent variable is the measured outcome. Essentially, the independent variable is the presumed cause, and the dependent variable is the observed effect.| Simply Psychology
A controlled experiment aims to demonstrate causation between variables by manipulating an independent variable while controlling all other factors that could influence the results. Its purpose is to show that changes in one variable (the independent variable) directly cause changes in another variable (the dependent variable).| Simply Psychology
In psychology research, validity refers to the extent to which a test or measurement tool accurately measures what it's intended to measure. It ensures that the research findings are genuine and not due to extraneous factors. Validity can be categorized into different types, including construct validity (measuring the intended abstract trait), internal validity (ensuring causal conclusions), and external validity (generalizability of results to broader contexts).| Simply Psychology
The experimental method involves the manipulation of variables to establish cause-and-effect relationships. The key features are controlled methods and the random allocation of participants into controlled and experimental groups.| Simply Psychology
