Hierarchical process memory: memory as an integral component of information processing

Open access
Hasson, Uri, Chen, Janice, Honey, Christopher J.·2015·Trends in Cognitive Sciences

Abstract

Models of working memory (WM) commonly focus on how information is encoded into and retrieved from storage at specific moments. However, in the majority of real-life processes, past information is used continuously to process incoming information across multiple timescales. Considering single-unit, electrocorticography, and functional imaging data, we argue that (i) virtually all cortical circuits can accumulate information over time, and (ii) the timescales of accumulation vary hierarchically, from early sensory areas with short processing timescales (10s to 100s of milliseconds) to higher-order areas with long processing timescales (many seconds to minutes). In this hierarchical systems perspective, memory is not restricted to a few localized stores, but is intrinsic to information processing that unfolds throughout the brain on multiple timescales.

  • The brain constructs simulations (as concepts) across many different timescales.

    “As a prediction generator, the brain is constructing simulations (as concepts) across many different timescales (i.e. integrating information across the few moments that constitute an event, but also across longer time frames at various scales; for similar ideas, see Wilson et al., 2010; Hasson et al., 2015).”

    From The theory of constructed emotion: an active inference account of interoception and categorization (2016) · cites this paper as Hasson et al., 2015

    The Abstract and “A method for mapping processing timescales” describe the brain integrating information across a hierarchy of timescales, from moments to minutes. That supports the cited comparison to a similar multiscale idea, but these passages do not describe the brain constructing simulations as concepts. (LLM, conf=0.86)

  • Cortical processing timescales increase along a hierarchy from early sensory regions (tens of milliseconds) to high-order regions (hundreds of seconds).

    “Processing timescales increase from tens of milliseconds in early sensory regions (e.g. for detecting phonemes in early auditory areas), to a few seconds in mid-level sensory areas (e.g. for integrating words into sentences), up to hundreds of seconds in regions including the temporoparietal junction, angular gyrus, and posterior and frontal medial cortex”

  • The topography of event timescales is broadly consistent with previous work measuring sensitivity to temporal scrambling.

    “This topography of event timescales is broadly consistent with that found in previous work (Hasson et al., 2015) measuring sensitivity to temporal scrambling of a movie stimulus”

  • The topography of event timescales provides converging evidence for the process memory framework.

    “The topography of event timescales revealed by our analysis provides converging evidence for an emerging view of how information is processed during real-life experience (Hasson et al., 2015).”

    From Discovering Event Structure in Continuous Narrative Perception and Memory (2017) · cites this paper as Hasson et al., 2015

  • The process memory framework argues that perceptual stimuli are integrated across longer and longer timescales along a hierarchy from early sensory regions to default mode network regions.

    “The “process memory framework” argues that perceptual stimuli are integrated across longer and longer timescales along a hierarchy from early sensory regions to regions in the default mode network.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
