In which the impact of EMOTION was tested for each level of WEIGHT.As shown in Figure A, participants made a “Fat” categorizing selection a lot more frequently for sad male faces in comparison to neutral male faces within the , , , and weight levels, t p d .; t p d .; t p d .; t p d .As expected, there was no substantial distinction in any WEIGHT levels by EMOTION in female faces, all p .Lastly, to verify no matter whether the sex of participants had any systematic impact on our findings, we performed an exploratory fourway repeatedmeasures ANOVA that integrated participants’ sex as an added betweengroup element.Nonetheless, we couldn’t observe a important major or threeway interaction impact involving sex (all p ).As stated earlier, we hypothesized that the emotional expressions (neutral or sad) of facial stimuli would influence perceptual judgment on the weight of faces.More particularly, we hypothesized that the perceptual selection threshold that determines binary responses (normal vs.fat) of our twoalternative forced option task could be modulated by the presence of taskirrelevant negative impact of facial stimuli, resulting in additional sensitive (frequent) “Fat” choices for sad faces in comparison to neutral faces, even in reduce levels of weightiness.The systematic adjust on the perceptual threshold we hypothesized (i.e lower choice threshold for sad faces) was tested by comparing psychometric curve match parameters estimated from each individual.In the NakaRushton contrast response model we employed, the C parameter represents the perceptual threshold or the PSE.The indicates of C parameters for male neutral and male sad faces had been .(SE ) and .(SE ), respectively.On theWeight level of Tilfrinib site morphed faces Face type Male neutral Male sad Female neutral Female sad . . . . . . . . . . . . . . . . . . . . . . . .Frontiers in Psychology www.frontiersin.orgApril Volume ArticleWeston et al.Emotion and weight judgmentFIGURE (A) Male face data.(B) Female face data.Average probability of fat responses as a function of weight levels (overweight) and emotional expressions.Error bars denote the SE of your mean.p .; p .; p .(C) For the weight judgment information, psychometric curves have been fitted by using the NakaRushton response function.A leftwardshift of a psychometric curve of Male Sad faces (red line) comparedto Male Neutral faces (blue line) was observed.A horizontal dotted line represents the probability of fat decision.(D) Scatter plot of your partnership amongst BAOP (Belief About Obese Persons) scores and C variations amongst Male Neutral faces ale Sad faces.Larger BAOP scores indicate a stronger belief that obesity just isn’t below the obese person’s manage.Solid line represents a linear fit.other hand, the indicates of C parameters for female neutral and female sad faces have been .(SE ) and .(SE .; see Table for any complete list of parameters).On these C parameters, we performed a twoway (GENDER EMOTION) repeatedmeasures ANOVA.We identified a significant interaction effect, F p partial along with a PubMed ID:http://www.ncbi.nlm.nih.gov/pubmed/21549324 important major impact of EMOTION, F p partial .Subsequent simple impact analyses have been carried out separately for male and female faces.As expected, we identified a important distinction of C parameters in male faces, t p d but no difference in female faces, t p d .It should really be noted that we did not observe any meaningful difference amongst C of male neutral faces and C of female neutral faces, t p d further confirming that the preceding signi.
