Object imagery is mentally picturing a thing itself: its shape, colour, texture. Some find single objects harder to imagine than scenes or layouts.
Duckett and Simons · Neuropsychologia
In 60 adults, neither questionnaire imagery scores nor average vividness predicted memory for scenes, but memories rated more vivid than a person's own average were more often correct. Re-analyzed aphantasia data showed the same trial-level link.

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.
Monzel and colleagues · Behavior Research Methods
Using existing data from 111 people, 38 classed as having little or no imagery, the authors propose a new way to score a test in which imagining a colored pattern makes it more likely to be seen when each eye sees a different pattern. Counting trials where people saw a mix, instead of dropping them, made the score agree better with self-reported imagery, but only when few clear trials were recorded. The score explained about a tenth of the variation in self-reports, and the authors judge it better at separating groups than individuals and too weak to classify one person.

In binocular rivalry tests, people with aphantasia were primed by attending to a visible striped pattern but showed no sign of attentional templates when it was absent. The authors conclude templates and imagery are closely linked.
