No full textImplicit prejudices based on race and sexual orientation do not predict COVID-19 vaccine hesitancy in Italy during the post-pandemic era
No full textBackground. COVID-19 has led to over 14 million deaths worldwide, evidencing the importance of
investingating its antecedents. However, despite the increasing research efforts, the psychological
underpinnings of vaccine rejection and vaccine hesitancy have not yet been completely understood.
Previous literature showed in large samples that vaccine rejection is associated with explicit prejudice
towards immigrants in UK and Ireland (Murphy et al., 2021).
Aims. Building upon the existing literature and recognizing a research gap, our research aims to delve into
the intricate nexus of factors contributing to vaccine hesitancy. Specifically, we investigate the role of social
behavior by focusing on implicit prejudices concerning Race and Sexual Orientation.
Method. The present study involved the administration of two Implicit Association Tests (IATs), focusing
on Race and Sexual Orientation, and VH score. A regression (employing generalized linear models) with
the IAT score as predictor and VH score as predicted for each IAT, and two independent samples T-test for
comparing race IAT and sexual orientation IAT scores in participants with high- vs low VH.
Results. Results showed that vaccine hesitancy and vaccine rejection are not releted to implicit prejudice
for either race and sexual orientation in our sample of young Italian students in the post-pandemic era

Off-line rTMS of left Dorsolateral Prefrontal Cortex reduces food cravings in females but not males.
No full textDysfunction of the left dorsolateral prefrontal cortex (DLFPC) has been crucially implicated in craving for food. Here, we aimed at expanding this result by investigating gender differences in food cravings in female (n=8; age=20.38yrs; BMI=22.54) and male (n=9; age=20.67yrs; BMI=20.89) healthy participants. Off-line repetitive transcranial magnetic stimulation (rTMS; 15 mins, 900 pulses) was administered on the left DLPFC and on the vertex (as control condition) before and after exposure to sweet food. Desire for salty and sweet food consumption was assessed by visual analogue scales (VAS) and calories consumed before and after rTMS. While after vertex-rTMS women expressed higher desire for sweet but not for salty foods with respect to men, desire for food did not change and remained stable before and after DLPFC-rTMS. No differences were observed in the consumed calories after the two rTMS stimulation. Our results provide preliminary evidence of a brain mechanism by which cognitive inhibition decreases the desire for sweet foods and implicates lower ability to suppress cravings in women as a contributing factor to gender differences possibly in binge eating disorder and obesity

Neural underpinnings of superior action prediction abilities in soccer players.
Full text linkThe ability to form anticipatory representations of ongoing actions is crucial for effective interactions in dynamic environments. In sports, elite athletes exhibit greater ability than novices in predicting other players actions, mainly based on reading their body kinematics. This superior perceptual ability has been associated with a modulation of visual and motor areas by visual and motor expertise. Here, we investigated the causative role of visual and motor action representations in experts ability to predict the outcome of soccer actions. We asked expert soccer players (outfield players and goalkeepers) and novices to predict the direction of the ball after perceiving the initial phases of penalty kicks that contained or not incongruent body kinematics. During the task, we applied repetitive transcranial magnetic stimulation (rTMS) over the superior temporal sulcus (STS) and the dorsal premotor cortex (PMd). Results showed that STS-rTMS disrupted performance in both experts and novices, especially in those with greater visual expertise (i.e. goalkeepers). Conversely, PMd-rTMS impaired performance only in expert players (i.e. outfield players and goalkeepers), who exhibit strong motor expertise into facing domain-specific actions in soccer games. These results provide causative evidence of the complimentary functional role of visual and motor action representations in experts action prediction
