Electrophysiological Evidence of Enhanced Processing of Novel Pornographic Images in Individuals With Tendencies Toward Problematic Internet Pornography Use.

1 The simple-effect of condition (Bonferroni corrected p = 0.025) revealed that novel stimuli (5.58 ± 3.30 μV) evoked larger amplitudes compared with familiar stimuli (2.68 ± 2.90 μV) in the high tendencies toward PIPU [ F (1, 26) = 57.74, p < 0.001, η 2 p = 0.69], but there was only a marginally significant difference in amplitude between stimuli (4.98 ± 3.51 vs. 3.71 ± 3.19 μV) for the low tendencies toward PIPU [ F (1, 24) = 5.62, p = 0.026, η 2 p = 0.19] groups (see Figure 2 ).
