Auditory aphantasia is the inability to voluntarily hear sounds, music, or voices in your mind, sometimes called a silent mind. Closely tied to inner speech.

Researchers expand aphantasia definition beyond "inability to visualize." This broader framework impacts how we understand and identify with the condition.

My journey understanding the cognitive profiles of aphantasia and hyperphantasia started when I learned at age 30 that most of you have a superpower I don’t.

Researchers found that anauralia and aphantasia share a 0.8% prevalence but have distinct psychological profiles. This suggests that the absence of sensory imagery is modality-specific rather than a single, unified condition.
Suggate, Milton and Tree · Neuropsychologia
People with aphantasia were more accurate but slower than controls on multimodal mental comparison tasks. This suggests that sensory cognition can be successfully achieved through propositional rather than imagistic strategies.
Rollo and colleagues · Brain and Cognition
In 49 healthy young adults, 20 minutes of weak, randomly fluctuating electrical current over both temples lowered ratings of how easily they could change one imagined sound into another, compared with a sham session on another day. Ratings of how vivid the imagined sounds were fell by a slightly smaller amount, a trend that did not reach significance. The ratings were self-reported during stimulation, and because no other brain area was stimulated for comparison, the authors cannot rule out a general effect, for example on attention.

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.
