|Title||Processing Resources, Prices & Purchase Likelihood|
|If the original article contained multiple experiments, which one did you attempt to replicate? e.g., you might respond 'Study 1' or 'Experiment 4'.||Study 3|

|Brief Statement of Original Result||2 (processing resources constrained or unconstrained) X 2 (price round, $80, or non-round, $81.43) between subjects design. Outcome variable is self-reported purchase likelihood of digital camera binoculars on a 9-point scale. When processing resources are constrained, purchase likelihood is higher if the price is $80, but when processing resources are unconstrained, purchase likelihood is higher if the price is $81.43.|
|Type of Replication Attempted||Fairly Direct Replication|
|Result Type||Failure to Replicate|
|Difference?||Same Direction, .82, .48|
|Number of Subjects||801|
|Number of Subjects in Original Study||177|
|Year in which Replication Attempt was Made||2015|

|Detailed Description of Method/Results||
Participants were randomly assigned by Qualtrics to either remember a 7-letter randomly generated string or a single letter (all participants were asked to remember either the same string or letter, each of which was randomly generated.)|
Participants were next asked to evaluate a pair of digital camera binoculars. A photo of the binoculars was presented, with the phrase "This is a pair of binoculars and digital camera combo perfect for viewing all the action up-close and capturing it digitally as well." and a list of three features. The price was displayed beneath the binoculars. Participants were randomly assigned by Qualtrics to either see a round price, $80, a non-round price, $81.43, and a non-round lower price, $78.57. The first two prices are identical to those used in the original study, while the third price is new to this replication.
Participants were then asked to indicate their likelihood of purchasing the digital camera binoculars on a 9-point scale, where 1 = very unlikely and 9 = very likely.
The study consisted of six possible conditions. Four of the six conditions were replications of the original study. The two other conditions, corresponding to the non-round lower price, were added to test the effect of round prices with a price point lower than $80.
A two-way ANOVA predicting purchase likelihood from price and processing resources yields no significant main effects (main effect for price F(2, 795) = .72, p = .49; main effect for resources F(1, 795) = .01, p = .94; and no significant interaction effect F(2, 795) = .37, p = .69).
Focusing on the 4 replication conditions, a 2 way ANOVA predicting purchase likelihood from price and processing resources yields no significant main effects (main effect for price F(1, 527) = .10, p = .75; main effect for resources F(1, 527) = .07, p = .80; interaction effect F(1, 527) = .42, p = .52).
Simple effects analyses did not replicate the simple effects reported in the paper. The simple effect for constrained processing resources, t(527) = .22, p = .82, d = .019 ; the simple effect for unconstrained processing resources, t(527) = .71, p = .48 d = .06.
