Title Memory compression in Vis. Working Memory
If the original article contained multiple experiments, which one did you attempt to replicate? e.g., you might respond 'Study 1' or 'Experiment 4'. Both experiments

Brief Statement of Original Result Observers remembered more colors when the presences of colors were not independent of each other.
Type of Replication Attempted Fairly Exact Replication
Result Type Successful Replication
Difference? Same Direction, 0.001
Number of Subjects 40
Number of Subjects in Original Study
Year in which Replication Attempt was Made 2011
Name of Investigators (Real Names Required) Liqiang Huang
Detailed Description of Method/Results 8 items of 8 different colors were presented. For each subject, these colors randomly form 4 frequent pairs (2 colors/pair). In block 1-7, each display include 2 familiar pairs and the other 4 colors are randomly distributed. In block 8-10, all 8 colors are randomly distributed. It was found that the number of memorized colors indeed benefit significantly from the covariance of colors. This replicated the original finding.
Any Known Methodological Differences
(between original and present study)?
I tried a fairly exact replication. Some details (e.g., sizes and arrangements of items, exact color appearance) are different. But given this is a successful replication, these do not matter too much.
