Imagine, and you will find – Lack of attentional guidance through visual imagery in aphantasics

Aphantasia is the condition of reduced or absent voluntary imagery. So far, behavioural differences between aphantasics and non-aphantasics have hardly been studied as the base rate of those affected is quite low. The aim of the study was to examine if attentional guidance in aphantasics is impaired by their lack of visual imagery. In two visual search tasks, an already established one by Moriya (Attention, Perception, & Psychophysics, 80(5), 1127-1142, 2018) and a newly developed one, we examined whether aphantasics are primed less by their visual imagery than non-aphantasics. The sample in Study 1 consisted of 531 and the sample in Study 2 consisted of 325 age-matched pairs of aphantasics and non-aphantasics. Moriya’s Task was not capable of showing the expected effect, whereas the new developed task was. These results could mainly be attributed to different task characteristics. Therefore, a lack of attentional guidance through visual imagery in aphantasics can be assumed and interpreted as new evidence in the imagery debate, showing that mental images actually influence information processing and are not merely epiphenomena of propositional processing.

Perspective-Taking: In Search of a Theory

Perspective-taking has been one of the central concerns of work on social attention and developmental psychology for the past 60 years. Despite its prominence, there is no formal description of what it means to represent another’s viewpoint. The present article argues that such a description is now required in the form of theory—a theory that should address a number of issues that are central to the notion of assuming another’s viewpoint. After suggesting that the mental imagery debate provides a good framework for understanding some of the issues and problems surrounding perspective-taking, we set out nine points that we believe any theory of perspective-taking should consider.

Sign theory at work: The mental imagery debate revisited

This article attempts to give a plausible explanation to the long-debated question about the nature of mental imagery (MI). The traditional approach to this question is based on the representational paradigm, which, I claim, is misguided. Instead of representational aspects of mental imagery, I emphasize the functions of mental imagery, the variety of properties that images exhibit in experimental studies, and the relations between different characteristics of images, their functions and the subject of imagery. That is, I propose to account for mental imagery as a sign system, consisting of different types of signs. A mental image can contain important properties as parts of the complex sign. This approach to the explanation of the nature of MI is beneficial, since it suggests the phenomenon of mental imagery, which overcomes some long-standing controversies on the issue.

The heterogeneity of mental representation: Ending the imagery debate

The possible ways that information can be represented mentally have been discussed often over the past thousand years. However, this issue could not be addressed rigorously until late in the 20th century. Initial empirical findings spurred a debate about the heterogeneity of mental representation: Is all information stored in propositional, language-like, symbolic internal representations, or can humans use at least two different types of representations (and possibly many more)? Here, in historical context, we describe recent evidence that humans do not always rely on propositional internal representations but, instead, can also rely on at least one other format: depictive representation. We propose that the debate should now move on to characterizing all of the different forms of human mental representation.

Reading imaginatively: The imagination in cognitive science and cognitive literary studies

I argue that literary studies can contribute to the “imagery debate” (between pictorialist, propositionalist, and enactivist accounts of mental imagery). While imagery questionnaires are pictorially configured and conflate imagining and seeing with pictorial representation, literary texts can exploit language's capacity for indeterminacy and therefore elicit very different imaginative experiences, thus illuminating the non-pictorial qualities of mental imagery.
