The term "short-term memory" (STM) is often vague. This paper proposes a hierarchical model where attention is a subset of activated long-term memory representations, offering clearer research directions.

Area of Science:

  • Cognitive Psychology
  • Neuroscience
  • Memory Research

Background:

  • The popular term "short-term memory" (STM) lacks a precise definition.
  • Existing definitions conflate distinct cognitive processes.
  • Ambiguity hinders clear empirical investigation.

Purpose of the Study:

  • To propose a more coherent and hierarchical conceptualization of short-term memory.
  • To differentiate between activated long-term memory representations and the focus of attention.
  • To establish a framework for testable predictions in memory research.

Main Methods:

  • Conceptual analysis of existing short-term memory (STM) literature.
  • Development of a hierarchical model integrating long-term memory activation and attentional focus.

  • Discussion of research implications and testable hypotheses.

    • Main Results:

    • Short-term memory (STM) is redefined as a hierarchical construct.
    • Attention is conceptualized as a subset of currently activated long-term memory representations.
    • The proposed model offers a clearer distinction between memory activation and awareness.

    Conclusions:

    • A hierarchical model provides a more precise understanding of short-term memory (STM).
    • This conceptual refinement facilitates the generation of novel research questions.
    • The proposed framework enhances the empirical investigation of memory and attention.
