The Claim
Instrumental behavior, measured as spacebar presses to retrieve food memories, does not exhibit a consistent nonlinear relationship with time since last food consumption across empirical studies, suggesting that behavioral measures are less sensitive to abstinence duration than self-reports.
What the research says
Challenges is higher
Challenge is ahead, but a single strong supporting study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
The number of times people press a spacebar to recall food memories does not change in a predictable nonlinear way based on how long it has been since they last ate, and this behavioral measure is less responsive to food abstinence duration than people's own reports.
See the scientific wording
Instrumental behavior (spacebar presses to retrieve food memories) does not consistently show a nonlinear relationship with time since last food consumption across studies, indicating that behavioral measures may be less sensitive to abstinence duration than self-reports.
When a person hasn't eaten for a while, the brain's response to food-related signals becomes weaker over time, so actions like pressing a button to see food pictures don't keep increasing even though the person says they want food more.
What the research says
1 studyStudy: Connecting self-report and instrumental behavior during incubation of food craving in humans
People say they crave food more after not eating for a while, and this study found that their actions — like pressing buttons to see food pictures — also tend to increase after longer breaks, though not as strongly. So, behavior does change with time, contrary to what the claim says.
