|Detailed Description of Method/Results||
Spatial distance was primed by graphing a pair of points on a coordinate plane. In the three conditions the points were increasingly far apart. |
Participants completed the task in between a series of unrelated experimental tasks. They were provided with a sheet of paper (face down) and told not to flip it over until directed to. No other cover story was given. During the experiment the computer gave instructions to flip over the paper, which told participants to graph (one of three) coordinate points on the coordinate plane. Upon completing the task, participants responded to three questions, measuring the strength of their bond to their parents, siblings, and hometown on a scale from 1(not at all strong) to 7 (extremely strong).
At the conclusion of the experiment participants were probed for suspicion and debriefed.
Sixteen participants failed to complete the grid correctly and were removed from the analysis, leaving 167 participants. (Removal of participants did not change the results of the analyses.) A one-way ANOVA was used to test differences in bond strength between the three spatial-prime groups. As Figure 1 shows, there was a marginal difference between the conditions in the expected direction (close prime: M = 5.38, SD = 0.95; intermediate prime: M = 4.98, SD = 1.00; distance prime: M = 5.08, SD = 1.06), F(2, 158) = 2.43, p = .09. Cohen'ÃƒÂƒÃ‚ÂƒÃƒÂ‚Ã‚Â‚ÃƒÂƒÃ‚Â‚ÃƒÂ‚Ã‚Â™s d for the close v. distance conditions was .31 (original d = .64.)
The data were combined with another replication attempt made by the same authors (also available on psychfiledrawer) and examined with Bayesian parameter estimation. By specifying a region of practical equivalence (ROPE) around the null it is possible to accept the null if parameter estimates do not exceed this ROPE. We selected a ROPE of -0.1 to 0.1 for the standardized mean difference (effect size) of spatial prime when comparing close vs. distance conditions as effect sizes must be greater than |0.1| to be considered "small" (Cohen, 1988).
We used a vague prior to estimate the standardized mean difference between spatial distance and family bond strength given the combined sample of 412 participants. Using R scripts (Kruschke, 2011), we implemented Markov Chain Monte Carlo algorithms to generate a set of 100,000 standardized mean difference parameter values.
The R script outputs a histogram of credible parameter estimates (Figure 2) and reports the highest density interval (HDI) that contains 95% of the estimates of effect size. The mean effect size estimate when comparing close vs. distance conditions was .14, 95% HDI [-.05, .36]. The HDI does not completely fall within our ROPE (-.10 to .10), preventing us from concluding in favor of the null hypothesis. However, given that 10.5% of the credible estimates of effect size were less than zero, and the mean effect size was d = .14, we find little support for the original medium sized effect reported (d = .64).

|Any Known Methodological Differences |
(between original and present study)?
|In the original study the experimenter provided plotting instructions, coordinates, and bond ratings together in a paper packet. To reduce expectancy effects, in our replications experimenters were blind to the purpose of the grid task. The experimenter provided only the coordinate grid and plotting instructions; all bond questions were administered on the computer.|
