Why indecisive trials matter: Improving the binocular rivalry imagery priming score for the assessment of aphantasia
Researchers discovered that incorporating mixed trials into binocular rivalry scores increases the task's predictive validity for mental imagery. This provides a more reliable and efficient objective measure for identifying individuals with aphantasia.

Beyond words: Examining the role of mental imagery for the Stroop effect by contrasting aphantasics and controls
People with aphantasia showed a reduced Stroop effect in accuracy compared to controls. This suggests that mental imagery of color words interferes with perception, identifying imagery as a partial cause of this cognitive interference.

Stage 2 Registered Report: Propositional Thought Is Sufficient for Imaginal Extinction as Shown by Contrasting Participants With Aphantasia, Simulated Aphantasia, and Controls
People with aphantasia achieved successful fear extinction despite lacking mental imagery. This indicates that propositional thought is sufficient for exposure therapy, making these clinical treatments viable for those without a mind's eye.

Affective processing in aphantasia and potential overlaps with alexithymia: Mental imagery facilitates the recognition of emotions in oneself and others
People with aphantasia show reduced emotional responses to verbal stimuli and slower recognition of others' emotions. This suggests mental imagery is a vital mechanism for amplifying emotional experiences and facilitating social cognition.

Hippocampal-occipital connectivity reflects autobiographical memory deficits in aphantasia
People with aphantasia recalled fewer internal memory details, linked to reduced hippocampal-visual cortex connectivity. This suggests that functional interaction between these regions is essential for retrieving vivid personal memories.

Neuronal activation patterns during self-referential pain imagination
Imagining painful scenarios recruits brain regions associated with actual pain processing, including the somatosensory cortex. This suggests pain imagination is a top-down simulation that may be significantly altered in people with aphantasia.

No verbal overshadowing in aphantasia: The role of visual imagery for the verbal overshadowing effect
People with aphantasia did not experience the verbal overshadowing effect when describing faces. This suggests that the effect relies on visual imagery to interfere with recognition memory.

The role of dopamine in visual imagery—An experimental pharmacological study
Researchers are investigating whether acute dopamine depletion reduces the strength of voluntary mental imagery. This could identify a neurochemical mechanism for aphantasia and suggest potential pharmacological interventions to enhance imagery.

Where’s Wanda? The influence of visual imagery vividness on visual search speed measured by means of hidden object pictures
People with aphantasia were significantly slower than controls at finding hidden objects in complex scenes. This indicates that mental imagery facilitates top-down processing in real-world visual perception.

No increased prevalence of prosopagnosia in aphantasia: Visual recognition deficits are small and not restricted to faces
People with aphantasia show mild, general visual recognition deficits rather than a specific link to prosopagnosia. This suggests that mental imagery plays a broad role in enhancing recognition memory across various stimulus types.

Imaginal extinction without imagery: Dissociating the effects of visual imagery and propositional thought by contrasting participants with aphantasia, simulated aphantasia, and controls
Researchers found that imaginal extinction of fear can occur without visual imagery in people with aphantasia. This suggests propositional thought alone can drive fear reduction, potentially making exposure therapy more tolerable for patients.

No general pathological significance of aphantasia: An evaluation based on criteria for mental disorders
Researchers found aphantasia generally lacks pathological significance despite minor memory impairments and distress in a subgroup. This suggests aphantasia should be classified as a non-clinical cognitive variant rather than a disorder.

Is it really empathy? The potentially confounding role of mental imagery in self-reports of empathy
Aphantasics scored lower on verbal empathy tests but matched controls on image-based assessments. This suggests traditional empathy measures are confounded by imagery ability rather than reflecting true differences in emotional capacity.

Memory deficits in aphantasics are not restricted to autobiographical memory – Perspectives from the Dual Coding Approach
Aphantasics performed worse than controls in visual and verbal short-term and long-term memory tasks. This suggests visual imagery is a fundamental component of general memory systems, extending well beyond autobiographical recall.

Imagine, and you will find – Lack of attentional guidance through visual imagery in aphantasics
Aphantasics lack the attentional guidance typically provided by visual imagery during search tasks. This suggests mental images are functional components of cognition rather than mere epiphenomena.
