Replicability-Report for COGNITION & EMOTION

Cognition & Emotion is published by Taylor and Francis. The journal started publishing articles in 1988.

SCImago ranks Cognition & Emotion as #158 of all psychology journals with an SJR-Impact-Factor of 1.3 in 2014. At present, the replicability-report is based on articles published from inception in 1988 to 2015. During this time, Cognition and Emotion published 1,557 articles. The replicability-report is based on 1,081 articles that reported one or more t or F-test in the text of the results section (results reported in Figures or Tables are not included).  The test-statistic was converted into z-scores to estimate post-hoc-power.  The analysis is based on 6,710 z-scores in the range from 2, just above the 1.96 criterion value for p < .05 (two-tailed), to 4.

PHP-Curve CogEmo

Based on the distribution of z-scores in the range between 2 and 4, the average power for significant results in this range is estimated to be 61%. This estimate suggests that 61% of the published significant results in this range are predicted to produce a significant results in an exact replication study with the same sample size and power (results with z > 4 are expected to replicate with nearly 100%).

The same method was used to estimate power for individual years.

The results show a flat line. However, replicability scores in the past five years have been consistently above the historic average. The replicability score in 2015 was 67%, which is above the average for psychology journals publishing research on emotion. The 2015 score can still change as more data are becoming available.
