In an experiment on short-term memory by Wright (discussed in class), the subjects were pigeons, monkeys, and humans. A sequence of 4 pictures was presented on each trial and memory was tested for pictures at each position after various delays. When subjects were tested immediately after a trial, recall was highest for the picture. When recall was tested after the longest delay, recall was highest for the picture:

Last;First.

Explanation:

In an experiment on visual short-term memory by Wright A. A in 2015, the subjects were pigeons, rhesus monkeys and humans. A sequence of four (4) pictures was presented on each trial and memory was tested for pictures at each position after various delays.

When subjects were tested immediately after a trial, recall was highest for the last picture.

However, when recall was tested after the longest delay, recall was highest for the first picture.
