Brief Statement of Original Result In a recognition task, inverting sexualized images of male targets produces longer response times than upright sexualized male targets. The difference is less pronounced when inverting sexualized female targets.
Type of Replication Attempted Highly Direct Replication
Result Type Successful Replication
Difference? Not Applicable
Number of Subjects 102
Number of Subjects in Original Study 78

Detailed Description of Method/Results Participants viewed 24 images of sexualized males and 24 images of sexualized females. Half of each were presented in an upright position, and half were inverted. (Stimuli were not counterbalanced across upright/inversion condition, in accordance with the original study's methods.) Participants were then asked to indicate which of two L-R mirror images had appeared earlier.

The study used a 2 (Position: Upright vs. Inverted) x 2 (Target Sex: Male vs. Female) x 2 (Participant Sex: Male vs. Female) design, in which the Position and Target Sex were manipulated within subjects while Participant Sex was treated as a between-subjects factor. The main dependent variable being analyzed is response time for correct responses.

The original results reported that inverted bodies would produce longer response times than upright bodies, and the current study replicated this effect, F(1,100)=9.82, p=.002, partial eta squared=.089. The original results also reported a marginally significant interaction between Position and Target Sex (p=.096, partial eta squared=.036), while the current study found a fully significant interaction, F(1,100)=16.40, p<.001, partial eta squared=.141. However, the current study confirmed the main point of the original analyses, in that response times for inverted female targets were not longer than response times for inverted male targets. In fact, the difference was significant in the opposite direction, t(101)=3.18, p=.002, which further supports the conclusions of the original study.

As in the original study, the current study also did not find any differences across target sex or participant sex (p's>.50).

The averages and standard deviations for response times for correct responses in each condition are listed below:

Male upright: 1655.82 (641.83)
Male inverted: 1927.51 (577.22)
Female upright: 1755.35 (783.74)
Female inverted: 1765.14 (579.43)
