Understanding depression in basic education teachers
Introduction Teacher mental health is a growing global concern, particularly in under-resourced educational systems. Depression among educators compromises not only individual well-being but also the quality and equity of education. This study investigates the prevalence of depressive symptoms among Brazilian basic education teachers and explores how structural inequalities, particularly gender, race, parenthood, and prior psychiatric history, co…
The impact of parenthood on mental health within the academic community
Members of the academic community who are parents, particularly mothers, often contend with an array of additional responsibilities that create a delicate balance between academic work on the one hand and childcare and household duties on the other. Consequently, they may experience a negative impact on both their scientific careers and mental well-being. This study seeks to explore the intricate relationship between parenthood and depression sym…

A critical reflection on internationalizing gender equality certification
Purpose Internationalisation in higher education (HE) has always been romanticised and idealised but there has been limited focus on the internationalisation of gender equality and Equality, Diversity and Inclusion (EDI) certification and the role of international partnerships. Certification and Award Schemes (CAS), such as the Athena Swan Charter, can promote gender equality, best practices exchanges and foster institutional changes. Nevertheles…
Threat directionality modulates defensive reactions in humans
Features of threatening cues and the associated context influence the perceived imminence of threat and the defensive responses evoked. To provide additional knowledge about how the directionality of a threat (i.e. directed-towards or away from the viewer) might impact defensive responses in humans, participants were shown pictures of a man carrying a gun (threat) or nonlethal object (neutral) directed-away from or towards the participant. Cardia…
Exploring the effects of Covid-19-related traumatic events on the mental health of university students in Brazil
University students are vulnerable to mental health issues during their academic lives. During the COVID-19 pandemic, university students faced mental distress due to lockdowns and the transition to e-learning. However, it is not known whether these students were also affected specifically by COVID-19-related traumatic events. This study examined the impact of COVID-19-related traumatic events on 2277 university students from two federal institut…

Addiction to ultra-processed foods as a mediator between psychological stress and emotional eating during the Covid-19 pandemic
Background The coronavirus disease 2019 (COVID-19) pandemic induced psychological distress, which is linked to emotional eating and symptoms of addiction to ultra-processed foods (UPFs). Objective This study aimed to investigate whether symptoms of addiction to UPFs mediate the relationship between psychological stress due to the COVID-19 pandemic and emotional eating behaviour. Methods A cross-sectional online study was conducted from May to Nov…
Bias against parents in science hits women harder
Worldwide, parenthood remains a major driver for the reduced participation of women in the job market, where discrimination stems from people’s biases against mothers, based on stereotypes and misconceptions surrounding the vision of motherhood in our society. In academia, parenthood may be perceived as negatively affecting scientists’ commitment and dedication, especially women’s. We conducted a survey amongst Brazilian scientists and found that…
The different impacts of Covid-19 on the mental health of distinct health care worker categories
The present study sought to explore the factors associated with the odds of having probable depression and posttraumatic stress disorder (PTSD) related to traumatic COVID-19 experiences and their impact on health care workers in distinct categories. In this cross-sectional study, 1843 health care workers (nurses, nurse technicians, physicians, physical therapists, and other healthcare workers) were recruited via convenience sampling. A survey was…
Ultra-Processed Foods Elicit Higher Approach Motivation Than Unprocessed and Minimally Processed Foods
Background: Ultra-processed foods (UPF) are becoming extensively available in the food environments. UPF are industrial formulations that are designed to maximize palatability and consumption through a combination of calorie-dense ingredients and chemical additives. UPFs are also aggressively marketed, which may make them more attractive than unprocessed/minimally processed foods (UMPF). Since consumers' purchase decisions are guided by food-evok…

Appetitive drives for ultra-processed food products and the ability of text warnings to counteract consumption predispositions
Objective The present study aimed to (i) assess the appetitive drives evoked by the visual cues of ultra-processed food and drink products and (ii) investigate whether text warnings reduce appetitive drives and consumers’ reported intentions to eat or drink ultra-processed products. Design In Study I, a well-established psychometric tool was applied to estimate the appetitive drives associated with ultra-processed products using sixty-four image …
Alcohol, emotion and attention
Among the known effects of alcohol on behavior, the modulation of cognitive functions (such as attention and memory), emotion, risk-taking and aggressive behavior are noteworthy. Here, we performed literature review in order to reinterpret alcohol effects on behavior according to the Alcohol Myopia Theory. According to this construct, there is a reduction of attentional resources during alcohol intoxication, which are primarily allocated to the m…
Avoidance of smoking
Previous studies have shown that the most threatening and arousing pictures prompt the greatest evidence of defensive activation. Emotional ratings of Brazilian warning pictures described them as unpleasant but moderately arousing. To intensify avoidance of the packages, future graphic warnings should therefore generate more arousal. The ratings for the Brazilian warning pictures indicated that, except for those depicting people smoking, judgemen…

Sustained and transient modulation of performance induced by emotional picture viewing
We investigated how viewing task-irrelevant emotional pictures affects the performance of a subsequent nonemotional visual detection task. Subjects performed target-detection trials following the offset of individual unpleasant, pleasant, and neutral pictures. Sustained interference occurred when subjects viewed unpleasant pictures (mutilated bodies) in a sequential, "blocked" fashion. Such slowing down of reaction time appeared to build up with …
