Reduction of interference effect by low spatial frequency information priming in an emotional Stroop task.

The affective prediction hypothesis assumes that visual expectation allows fast and accurate processing of emotional stimuli. The prediction corresponds to what an object is likely to be. It therefore facilitates its identification by setting aside what the object is unlikely to be. It has then been suggested that prediction might be inevitably associated with the inhibition of irrelevant possibilities concerning the object to identify. Several studies highlighted that the facilitation of emotional perception depends on low spatial frequency (LSF) extraction. However, most of them used paradigms in which only the object to identify was present in the scene. As a consequence, there have yet been no studies investigating the efficiency of prediction in the visual perception of stimuli among irrelevant information. In this study, we designed a novel priming emotional Stroop task in which participants had to identify emotional facial expressions (EFEs) presented along with a congruent or incongruent word. To further investigate the role of early extraction of LSF information in top-down prediction during emotion recognition, the target EFE was primed with the same EFE filtered in LSF or high spatial frequency (HSF). Results reveal a reduction of the Stroop interference in the LSF compared to the HSF priming condition, which supports that visual expectation, depending on early LSF information extraction, facilitates the inhibition of irrelevant information during emotion recognition.

Willingness to be vaccinated against COVID-19: the role of risk perception, trust in institutions, and affects.

Introduction: Vaccination is one of the most effective ways to stop the COVID-19 pandemic and prevent severe disease. This study aims to ascertain the determinants of COVID-19 vaccination acceptance in the French population before the vaccine was introduced (France's second lockdown) and during the roll-out of the vaccination campaign (France's third lockdown). We focus on the following as determinants of willingness to be vaccinated: risk perception, affects related to the risk, and trust in political and health institutions. Method: The study was conducted among two convenient samples including 591 and 474 participants. The results show that the timing of the crisis was important. While the intention to be vaccinated was relatively low before the vaccines were introduced, it became significantly higher when the vaccination campaign was deployed. Results: The results show that risk perception and trust in health institutions are the most relevant predictors of intention to be vaccinated. Discussion: Results are discussed in terms of the effectiveness of communication campaigns.

How regulation strategies protected or worsened emotional experience during France's three lockdowns: Prepandemic versus pandemic comparisons and longitudinal approach.

The COVID-19 pandemic remains hugely challenging, but its impact on emotional experience, especially over time, has often been neglected. The French Government imposed three COVID lockdowns with varying degrees of strictness that induced different types of emotional discomfort and emotion regulation. The present longitudinal study explored affect and emotion regulation strategies in each of these lockdowns, comparing samples assessed before and during the pandemic. The objective was to understand how government measures influenced subjective experience and how people adjusted their emotion regulation accordingly. The longitudinal lockdown sample comprised 164 participants (Mage = 37.60 years, SD = 12.50). Affect and emotion regulation were assessed in the first week of each of the three lockdowns (20-27 March 2020, 23-30 November 2020, and 19-26 April 2021). The 120 participants in the prepandemic (control) sample were drawn from previous studies focusing on affect and regulation strategies in natural everyday situations. Results indicated that affect deteriorated considerably, compared with prepandemic levels. Whereas activated negative affect (nervous and worried) tended to decrease, deactivated negative affect (sad and bored) increased. Regarding emotion regulation strategies, negative emotion expression was associated with more negative affect and less positive affect, while positive emotion expression and proactive behaviour were associated with a better emotional experience. A multivariate growth curve showed that in the absence of psychological support, stressful situations and repeated lockdowns do not induce people to make better emotion regulation strategy choices. As government restrictions had a negative impact on individuals' emotional experience, support programs should be implemented in future pandemics to promote emotion regulation.

Right wing authoritarianism is associated with race bias in face detection.

Racial discrimination can be observed in a wide range of psychological processes, including even the earliest phases of face detection. It remains unclear, however, whether racially-biased low-level face processing is influenced by ideologies, such as right wing authoritarianism or social dominance orientation. In the current study, we hypothesized that socio-political ideologies such as these can substantially predict perceptive racial bias during early perception. To test this hypothesis, 67 participants detected faces within arrays of neutral objects. The faces were either Caucasian (in-group) or North African (out-group) and either had a neutral or angry expression. Results showed that participants with higher self-reported right-wing authoritarianism were more likely to show slower response times for detecting out- vs. in-groups faces. We interpreted our results according to the Dual Process Motivational Model and suggest that socio-political ideologies may foster early racial bias via attentional disengagement.

Resting high frequency heart rate variability selectively predicts cooperative behavior.

This study explores whether the vagal connection between the heart and the brain is involved in prosocial behaviors. The Polyvagal Theory postulates that vagal activity underlies prosocial tendencies. Even if several results suggest that vagal activity is associated with prosocial behaviors, none of them used behavioral measures of prosociality to establish this relationship. We recorded the resting state vagal activity (reflected by High Frequency Heart Rate Variability, HF-HRV) of 48 (42 suitale for analysis) healthy human adults and measured their level of cooperation during a hawk-dove game. We also manipulated the consequence of mutual defection in the hawk-dove game (severe vs. moderate). Results show that HF-HRV is positively and linearly related to cooperation level, but only when the consequence of mutual defection is severe (compared to moderate). This supports that i) prosocial behaviors are likely to be underpinned by vagal functioning ii) physiological disposition to cooperate interacts with environmental context. We discuss these results within the theoretical framework of the Polyvagal Theory.
