Can you smell your grandmother's kitchen in your mind? Olfactory aphantasia is the inability to voluntarily conjure smell, on its own or alongside other missing senses.

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.

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.
Zeman · Neuropsychologia
Ten years after aphantasia was named, Adam Zeman argues it likely has several subtypes and that most abilities are spared, with memory for one's own past differing most. He urges an open mind in this young field.
Zeman and colleagues · Cortex
Researchers define aphantasia as the absence of voluntary sensory imagery, often extending beyond vision to other modalities. This formal definition establishes a standardized framework for classifying multisensory and global imagery deficits.
Monzel and colleagues · Cortex
Researchers propose defining aphantasia as the absence or reduction of voluntary sensory imagery across any modality. This unified terminology avoids a proliferation of new terms while acknowledging that imagery deficits can be specific or multisensory.
