People with aphantasia exhibit the inability to voluntarily generate or form mental imagery in their minds. Since term “aphantasia” was proposed by Zeman et al. 2015 describe this, it has gained increasing attention from psychiatrists, neuroscientists, and clinicians. Previous studies have mainly focused on definition, prevalence, measurement, its impacts individuals’ cognitive emotional processing, theoretical frameworks synthesizing existing findings, which contributed greatly our understanding of aphantasia. However, there are still some debates regarding conclusions derived research theories that were constructed various sources evidence. Building upon endeavors, current systematic review emphasizes future is much needed refine definition diagnosis aphantasia, strengthen empirical investigations at behavioral neural levels, more importantly, develop update theories. These multiple lines efforts could lead a deeper further guide researchers directions.

Human cognition relies on two modes: a perceptually-coupled mode where mental states are driven by sensory input and perceptually-decoupled featuring self-generated content. Past work suggests that imagined supported the reinstatement of activity in cortex, but transmodal systems within canonical default network also implicated mind-wandering, recollection, imagining future. We identified brain supporting using precision fMRI. Participants different scenarios scanner, then rated their several properties multi-dimensional experience sampling. found thinking involving scenes evoked or near network, while speech language network. Imagining-related regions overlapped with viewing listening to speech, respectively; however, this overlap was predominantly association networks, rather than adjacent unimodal networks. The results suggest networks support high visual auditory vividness. Different large-scale audiolinguistic

Speaking of mental imagery suggests a similarity between internal representations and external pictorial representations, such as drawings, paintings photographs. This perceived has led some philosophers cognitive scientists to consider that both types belong specific category known depictive representations. Since the role pictures often been explained in terms resemblance, same principle applied images. In this article, I start by reviewing these attempts. Then, put forward objections against core project behind attempts, particularly emphasizing what call 'homogeneity problem'. Finally, article proposes an alternative approach understanding drawing insights from literature on representation artifacts, namely recognitional accounts representation. argue one merits definition is it does not fall prey homogeneity problem other described previously.

Our eyes do not only respond to visual perception but also internal cognition involving imagery, which can be referred as coupling. This review synthesizes evidence on coupling across diverse domains including episodic memory and simulation, visuospatial memory, numerical cognition, object movement, body brightness imagery. In each domain, eye movements consistently reflect distinct aspects of mental imagery typically akin those seen in corresponding experiences. Several findings further suggest that may coincide with supports evidenced by improved cognitive performance. Available theoretical accounts serve at least two functional roles imagery: facilitating reconstruction indicating shifts attention. Moreover, recent insights into the neurobiology highlight substantially shared neural pathways externally internally directed cognition. The concludes identifying open questions promising avenues for future research such exploring moderating context individual differences
