Silent reading often involves phonological encoding of the text in addition to orthographic processing. The nature of the phonological code is debated, however: Is it an abstract code or does it contain information about the pronunciation of the visual stimulus? To answer this question, we investigated the relationship between articulation speed and reading speed, both for silent reading and reading aloud. We investigated whether people with fast articulation speed read faster than people with slow articulation speed. We recruited 94 participants, who in a Zoom session were asked to read short texts silently or aloud. They were also asked to talk about their lives and say the numbers 1-10 or the months of the year as quickly as possible. Finally, they completed an online vocabulary test and an author recognition test. Multiple regression analysis and cluster analysis showed that although the speed of reading aloud and silent reading correlated to some extent, they belonged to two different clusters. Reading aloud was mainly related to talking fluency and articulation speed, while silent reading was more related to vocabulary and knowledge about fiction authors. These findings are consistent with the hypothesis that the phonological code in silent reading typically does not contain articulatory information, although our data do not rule out the possibility that this may be the case for a small percentage of people or when people read more difficult texts.

Based on the model of emotion as social information, this study explores the effects of facial emotions and trustworthy behavior on trust decision-making in trust game through two experiments. The present study used trust game explores the impact of players' facial emotion, arousal and trustworthy behavior on individual trust decision-making through two experiments. The results can be summed up as follows: (1) in the repeated interaction with four players, individuals invest more in trustworthy players than untrustworthy players; (2) individuals invested more in trustworthy players with happy facial emotions, while untrustworthy players with angry facial emotions received less investment. High-arousal facial emotion results in a more extreme investment by the individual; (3) when the players' facial emotion and behavior are inconsistent, the individual will judge according to the player's current behavior, rather than the facial emotion or past behavior.

Persistent fatigue constitutes a prevalent and debilitating symptom in several diseases. The symptom is not effectively alleviated by pharmaceutical treatments, and meditation has been proposed as a non-pharmacological intervention. Indeed, meditation has been shown to reduce inflammatory/immune problems, pain, stress, anxiety and depression which are associated with pathological fatigue. This review synthesizes data from randomized control trials (RCTs) that explored the effect of meditation-based interventions (MeBIs) on fatigue in pathological conditions. Eight databases were searched from inception to April 2020. Thirty-four RCTs met eligibility criteria and covered six conditions (68% cancer), 32 of which were included in the meta-analysis. The main analysis showed an effect in favor of MeBIs compared to control groups (g = 0.62). Separate moderator analyses assessing control group, pathological condition, and MeBI type, highlighted a significantly moderating role of the control group. Indeed, compared to actively controlled studies, studies using a passive control group were associated with a statistically significantly more beneficial impact of the MeBIs (g = 0.83). These results indicate that MeBIs alleviate pathological fatigue and it seems that the studies with a passive control group showed a greater effect of MeBI on the reduction of fatigue compared to studies using active control groups. However, the specific effect of meditation type and pathological condition should be analyzed with more studies, and there remains a need to assess meditation effects on different types of fatigue (i.e., physical and mental) and in additional conditions (e.g., post-COVID-19).

The increasing number of Social Network Sites (SNSs) and their changing nature raise the question of why people use them. This research has a twofold objective: first, to develop a motivation scale for using SNSs; second, to compare the motivational SNSs profile of Facebook, Instagram, Twitter, Snapchat and LinkedIn. Two studies on 364 university students, using exploratory and confirmatory factor analyses, established six motivations: entertainment, social interaction, seeking information, instrumental use, self-documentation and self-enhancement. Regressions then examined the association between motivations for using SNSs, social influence measures (descriptive and injunctive norms), and frequency of use of Facebook, Instagram, Twitter, Snapchat, and LinkedIn. The results showed that social norms complement the motivations to use SNSs. Twitter use was associated with an information-seeking SNSs motivational profile. LinkedIn, Facebook, and Instagram were associated with self-documentation on SNSs. Snapchat was rather associated with instrumental motivations on SNSs. However, while all SNSs were associated with descriptive norms, only Facebook and LinkedIn were associated with injunctive norms (i.e., peer pressure). The results are discussed by applying a cross-media perspective to new motives behind SNSs use.

Paranoia consists of unfounded beliefs that harm will be caused with intent to hurt the subject. Paranoid thoughts exist on a continuum of severity from severe forms in several psychological pathologies to milder forms in a significant minority of individuals of the general population (Freeman, 2007). It can be measured using several types of questionnaires. One recent questionnaire that measures paranoia in both clinical and non-clinical populations is the revised Green et al., Paranoid Thoughts Scale (R-GPTS) (Freeman et al., 2019). This questionnaire is an improved version of the Green et al., Paranoid Thoughts Scale (GPTS) (Green et al., 2008) and has excellent psychometric properties. In the present study, the R-GPTS was translated into French and the psychometric properties of the new French version were evaluated in a sample of the general population (N = 600) and in a clinical sample (N = 22). Confirmatory factor analysis supported the original two-factor structure (social reference and persecution subscales) of the R-GPTS. Evidence of excellent internal consistency of the R-GPTS was found. Furthermore, good convergent and discriminant validity was also found. Test-retest reliability showed significant positive correlations over a 1-month period. The findings discussed above were found in the non-clinical sample. Lastly, the R-GPTS revealed good preliminary criterion validity established from the comparison between the clinical and the non-clinical groups. In conclusion, the French version of the R-GPTS is a valid and reliable tool to measure paranoia in the general population. Due to the small sample size of the clinical sample, further studies are needed in order to confirm good psychometric properties in clinical populations, even though our preliminary findings are promising.

In a preregistered research, we examined the relationships between conspiracy mentality (i.e., the individual susceptibility to endorse conspiracy theories, Bruder et al., 2013) and trust in three actors of the COVID-19 crisis: 1) Political institutions, 2) scientific and medical institutions, and 3) the medical personnel. While the two former groups have played a direct or indirect role in decisions related to public health measures, the latter has not. We expected all these relationships to be negative and mediated by the belief that the pandemic is instrumentalized by authorities to pursue secret agendas. In a study conducted with Belgian (N = 1136) and French (N = 374) convenience samples, conspiracy mentality negatively predicted trust in political institutions, and trust in scientific and medical institutions. These relations were partly mediated by belief that the pandemic is instrumentalized by authorities. In addition, distrust in political, medical and scientific institutions were highly and positively correlated, suggesting that these groups may be viewed as part of a same supra-ordinate category - the "Elites". By contrast, we found a small negative relationship between conspiracy mentality and trust in the medical personnel in the Belgian sample, but not in the French sample. Trust in the medical personnel was unrelated to the belief that the pandemic is instrumentalized, and only weakly related to distrust in political institutions. This suggests that individuals with a susceptibility to believe in conspiracy theories may not have a propensity to distrust all actors involved in the management of the pandemic, but only those directly or indirectly tied to decisions pertaining to public health measures.
