Inferences about mental states

Abstract

Human social cognition relies on an ability to predict what others will think, feel or do in novel situations. Research in social neuroscience has consistently observed several brain regions that contribute ubiquitously to these abilities, including medial prefrontal cortex and aspects of lateral and medial parietal cortex. Interestingly, parallel work has suggested that this same network of regions subserves several seemingly distinct phenomena—notably, the abilities to remember the past, imagine the future and visualize spatial layouts—suggesting the existence of a common set of cognitive processes devoted to projecting oneself into worlds that differ mentally, temporally or physically from one's current experience. This use of self-projection to understand others' minds requires perceivers to solve three distinct cognitive challenges: (i) generating a simulated facsimile of one's own hypothetical mental states in a given situation, (ii) suppressing one's own current mental states, and (iii) deciding on the appropriateness of simulated states for understanding a particular other person. The present paper reviews recent psychology and neuroscience research aimed at understanding the underlying mechanisms that allow humans to solve each of these cognitive challenges to use self-projection to predict and understand the mental states of others.

TL;DR

This review argues that humans infer others’ mental states partly through self-projection, supported by a shared MPFC/TPJ/medial parietal network also used for episodic memory, prospection, and spatial navigation. It outlines three challenges—simulating one’s own hypothetical states, suppressing one’s current states, and judging whether self is a valid proxy—and reviews evidence on similarity, preference prediction, and TPJ-mediated self–other distinction.

Key findings

  • Mentalizing consistently engages medial prefrontal cortex (MPFC), temporo-parietal junction (TPJ), and medial parietal cortex; the same network is implicated in remembering the past, imagining the future, and spatial navigation, suggesting a common self-projection process.
  • Self-projective mentalizing is restricted to similar others: ventral MPFC tracks perceived similarity during mentalizing, and repetition suppression occurs in ventral MPFC for self-judgments following judgments of a similar other but not a dissimilar other.
  • Predicting one’s own preferences engages ventral MPFC; patients with ventral MPFC damage show inconsistent preferences (e.g., A>B, B>C, but C>A), and less ventral MPFC activity accompanies far-future versus next-24-hours preference judgments, correlating with greater impatience for immediate rewards (e.g., willingness to wait one month for a larger payment).
  • TPJ is implicated in suppressing one’s own mental states during false-belief reasoning and in non-social attentional reorienting, suggesting a shared suppression/reorienting process.

Methods

  • Review article synthesizing psychology and neuroscience research; no new primary data or sample are reported.
  • Draws on fMRI, lesion, TMS, neuropsychological patient studies, repetition suppression, false-belief tasks, and attentional reorienting tasks.
  • Main analysis is a narrative synthesis linking brain regions to the cognitive challenges of self-projection.

Limitations

  • The paper states that how perceivers infer mental states of dissimilar others remains an unsettled challenge, that the exact cognitive process of TPJ has yet to be fully uncovered, and that additional work is needed to support the suggestion that self-preference prediction relies on simulation.
  • The paper states that relatively little research has directly examined how perceivers suppress their own mental states.
  • Evident from the text: as a review, conclusions depend on cited studies, some listed as submitted or in press, and no systematic meta-analysis or new empirical test is provided.

    Significantly less ventral MPFC activity accompanied predictions about the far future compared with the present.

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.
