Memorable Images & Orientation

My tests, using the recently published MIT image memorability algorithm, suggests that an image’s memorability can be affected by its orientation. Take the same image, rotate it 90-degrees, and the score changes.

Two Views (portrait vs. landscape) of the Same Abstract

First, for context (what are we looking at?), here’s how the abstract was made

Rotating seem “right”  to me at the time (two years ago)

Subconscious at work? I neither knew nor thought about “memorable” then.

Above – Memorability: High (score: 0.808 )

Below – Memorability: Medium (score: 0.627)

These scores are the probability that, having seen the image previously, you’d remember it when seen later. 81% vs 63% is quite a difference.

Landscapes, as a genre, are notoriously non-memorable – even iconic landscapes.

Could the different scores for these images be due to the fact that the brain subconsciously sees the 2nd image for what it really is & says “landscape, forget it”?
