“…Finally, despite the existence of individual differences in the profile view of the slant of the forehead (Adams et al, 2013;Oh et al, 2016;Guerrero et al, 2016;Guerrero et al, 2018a,) an aspect that can trigger some controversy is the anthropometric measurement SFD. However, a recent study found a high level of interobserver agreement in the visual assessment of the level of the forehead slant, whose measurement obtained a high correlation with the anthropometric SFD measurement (Guerrero et al, 2016;Guerrero et al, 2018a). This backs up the validity of the anthropometric SFD measurement used in this study.…”

“…Average of the three SFD measurements was used in the analyses. The same method has been used in previous investigations (Guerrero et al, 2016;Guerrero-Apolo et al, 2018a: Guerrero-Apolo et al, 2018b.…”

“…In short, the above-mentioned data suggest that morphological variations in prefrontal regions play a fundamental role in impulsiveness, both in healthy and clinical subjects.However, impulsiveness seems not to be solely under the control of the prefrontal cortex (Braquehais et al, 2010), since temporal regions are also implicated (Hanford et al, 2016;Lyoo et al, 2006 (Guerrero et al, 2016;2018a;2018b) we explored the relationship between the slant of the forehead degree (SFD) and the CT of the entire cortex, an aspect that is yet to be studied.…”

Impulsiveness is a multidimensional psychological construct with high clinical interest because it is a risk factor for several psychiatric disorders. This study was designed to investigate structural correlates of self-reported impulsiveness, measured by using the Short Scale of Impulsive Behaviour, Barratt Impulsiveness Scale and Zuckerman Sensation Seeking Scale V. As a secondary objective, and based on preliminary findings concerning the positive relationship between impulsiveness and the slant of the forehead degrees (SFD), we explore this relationship and the correlation between SFD and cortical thickness (CT) of the entire cortex. From a sample of 48 participants' structural magnetic resonance images, three self-reports measuring impulsiveness and SFD were obtained. CT of the whole cortex was obtained for each participant through Freesurfer. Correlations between impulsiveness and CT and between CT and SFD were analyzed. Correlations between impulsiveness and SFD were also analyzed. Results showed significant adjusted and corrected correlations, both negative and positive, between impulsiveness and CT. Five negative associations with fronto-temporal and occipital areas were found. Of the 15 positive correlations, eight were with the right anterior cingulate cortex and three with left superior frontal gyrus.Positive correlations between 14 impulsiveness scores and SFD were also found. In conclusion, CT in prefrontal and temporal areas influences self-reported impulsiveness in healthy adults. Furthermore, SFD could influence the CT of regions involved in impulsiveness. Finally, we suggest that a higher SFD higher self-reported impulsiveness in healthy adults.

“…Regarding specific facial variables, fWHR is one of the most studied, with evidence that linked it with leadership in both competitive and prosocial environments (Hahn et al, 2017), integrity (Ormiston et al, 2017), sexual desire, sociosexuality and fidelity intention (Arnocky et al, 2017) and some psychopathic personality traits such as boldness, dominance, egocentricity impulsivity and general psychopathic scores (Anderl et al, 2016). There are other facial variables that have yielded significant results such as the inclination of the forehead and impulsivity (Guerrero et al, 2016;Guerrero-Apolo et al, 2018a) and the volume of gray matter in certain areas of the cortex (Guerrero-Apolo et al, 2018b), age, testosterone and strength with the lower/full face ratio, cheekbone prominence and fWHR-lower (Hodges-Simeon et al, 2016), or the difference of widths between bizygomatic and bigonial arches with traits such as self-reliance and the ability/ impairment to express and feel emotions (Gabarre-Mir et al, 2017). This impairment to express or feel emotions could be explained by the deficit in emotional information processing hypothesis.…”

The bizygomatic width when compared to the bigonial width (WD) has been proposed as a craniofacial marker of some social and personality traits, such us self-reliance or the ability to express emotions. However, no studies have examined the association between WD and psychopathic traits, as happens with other craniofacial variables such us the facial width-to-height ratio (fWHR). In a sample of 70 adults (male and female) we took measures of the bizygomatic and the bigonial arches. Subjects performed self-assessment tests to evaluate their self-reliance, their alexithymia and emotional expressiveness and their coldheartedness or callousunemotional. Results showed a significant relationship between WD and self-reliance, emotional expression and alexithymia, and a tendency towards significance with general psychopathic scores. Additionally, we found a modificatory effect of the variables sex and age when analyzing the influence of the WD on the Factor 3-"Coldheartedness" of the Psychopathic Personality Inventory-Revised (PPI-R), where this effect diminished depending on the subject's sex and age. Results suggested that the WD seem to be a good marker to be taken into consideration in further research that examines craniofacial traits and personality traits of the socio-emotional field.
