Main question
Do people with self-reported porn problems show an addiction-like neural response?
Summary
Prause and colleagues (2015) measured an EEG signal (the late positive potential) while people with self-reported pornography problems viewed sexual images. They found no addiction-like amplified response, and argued the results are inconsistent with a “porn addiction” model.
Why it matters
This study is important for the behavioural addiction debate because it provides a skeptical data point. It has itself been criticized, and its interpretation remains contested. It is included here to represent both sides of the neural cue reactivity question honestly.
Findings
- Found that people who reported problems with pornography did not show the amplified neural response to sexual images that an addiction model would predict.
- Interpreted the results as inconsistent with a 'porn addiction' framing.
Limitations
- Small sample size.
- Interpretation is contested; the study has been criticized on methodological and conceptual grounds.
- A single EEG measure (late positive potential) cannot settle a complex classification question.
- verification needed (DOI/PMID not recorded)
Clinical relevance
Provides a skeptical data point against "porn addiction".
Relevance to problematic pornography use
Contested evidence relevant to the addiction framing of PPU.
