Zeman and colleagues · Trends in Cognitive Sciences
Replying to a proposal that aphantasia reflects broken mental "rendering," this letter argues that conscious object imagery is unlikely to be a useless by-product. Links with memory, empathy and emotion suggest it may support social life.
Balaban and Ullman · Trends in Cognitive Sciences
This short letter replies to a proposal that visual imagery, which it treats as the mind's "graphical rendering", plays a central role in social life. It agrees imagery may matter socially but doubts a direct link. Instead it suggests an indirect one: pictures, seen or imagined, may stir old emotional systems that words cannot trigger, which could explain why people with aphantasia react less to written descriptions of distressing events. It still argues that rendering is probably not crucial and that much of imagination's work is done by simulating how things physically behave rather than by making pictures.
Nanay · Trends in Cognitive Sciences
Aphantasia is a heterogeneous condition with distinct subtypes, including variations in voluntary control and sensory modalities. Recognizing these differences is essential for developing accurate experimental methodologies and explanations.
Balaban and Ullman · Trends in Cognitive Sciences
Researchers propose that the mind separates physical simulation from graphical rendering, much like a game engine. This suggests aphantasia may be a case of "broken rendering" where underlying spatial and physical representations remain intact.
Liu and Bartolomeo · Trends in Cognitive Sciences
In this Letter, the authors propose that aphantasia involves weaker functional links between high-level visual areas and the left prefrontal cortex. They argue this may explain how visual knowledge survives without imagery, pending confirmation.
Michel and colleagues · Trends in Cognitive Sciences
Aphantasia may involve nonconscious imagistic representations that lack phenomenal awareness, similar to blindsight. This suggests the condition is primarily a deficit of conscious access rather than a total absence of mental imagery.
Zeman · Trends in Cognitive Sciences
About 1% of people report no visual imagery and about 3% report imagery as vivid as seeing, and objective tests are starting to back these reports up. The review suggests conscious imagery is not needed for thinking or creativity.
Palombo, Sheldon and Levine · Trends in Cognitive Sciences
Autobiographical memory varies significantly across individuals, ranging from highly superior to severely deficient capacities. This suggests that memory is a trait-like profile driven by distinct neural connectivity and cognitive strategies.
Pearson and colleagues · Trends in Cognitive Sciences
This review argues that visual imagery works like a weak form of seeing, with brain activity resembling perception's as early as the primary visual cortex. It also covers intrusive imagery in disorders such as PTSD and imagery-based therapy.
Pearson and Westbrook · Trends in Cognitive Sciences
Researchers propose a dichotomous framework for phantom perception, distinguishing between voluntary mental imagery and involuntary experiences like illusions or synesthesia. This classification helps unify diverse sensory phenomena and provides a roadmap for studying the neural mechanisms of constructive perception.
