Automatic behavioural responses to valence: Evidence that facial action is facilitated by evaluative processing

Are motor schemata of facial action spontaneously activated upon the processing of evaluative information? In this case, the processing of positive evaluative information should immediately trigger the motor schema of smiling, and the processing of negative information should trigger frowning. This hypothesis was tested in two experiments in which participants were required to respond to positive and negative words by either smiling or frowning. Electromyogram (EMG) activity was recorded over the brow muscle region (corrugator supercilii) and over the cheek muscle region (zygomaticus major) in order to quantify the latency of muscular response as a dependent measure. In Experiment 1 we found that participants were faster at contracting their zygomaticus muscle (which is involved in smiling) when evaluating positive words, and faster at contracting their corrugator muscle (which is involved in frowning) when evaluating negative words. In Experiment 2, participants were required to respond with the contraction of one of the two muscles whenever a word appeared on the computer screen. Again, we found that responses were faster to congruent response valence combinations than to incongruent response valence combinations. These findings support the hypothesis that evaluative processing is directly linked to motor schemata of facial muscles.     

When did her smile drop? Facial mimicry and the influences of emotional state on the detection of change in emotional expression

Participants in manipulated emotional states played computerised movies in which facial expressions of emotion changed into categorically different expressions. The participants' task was to detect the offset of the initial expression. An effect of emotional state was observed such that individuals in happy states saw the offset of happiness (changing into sadness) at an earlier point in the movies than did those in sad states. Similarly, sad condition participants detected the offset of a sad expression changing into a happy expression earlier than did happy condition participants. This result is consistent with a proposed role of facial mimicry in the perception of change in emotional expression. The results of a second experiment provide additional evidence for the mimicry account. The Discussion focuses on the relationship between motor behaviour and perception.     

Culture,Burnout, and Engagement: A Meta-Analysis on National Cultural Values as Moderators in JD-R Theory

Despite prominence and increasing application of the Job Demands-Resources (JD-R) theory across national contexts, the role of culture has not yet been systematically explored. We conducted a meta-analysis of 132 independent samples from 120 studies across 5 global regions (total N = 101,073) to fill this void. Our paper responds to long-standing concerns around neglecting differences in the relationships of workplace factors with burnout and engagement across national cultures by testing for a moderating role within JD-R theory. Results suggest strong support for the direct job demands-burnout and job resources-engagement pathways. Regarding the role of culture, our study reveals moderating roles for five out of six cultural dimensions using Hofstede’s framework. Interestingly, these cultural dimensions present a moderating impact towards relationships with either job demands or job resources, yet not both. Our findings offer a valuable starting point for further theoretical developments that can impact international business and global mobility. While these insights suggest a role of national cultural context in JD-R studies, sensitivity analyses showed that the findings were only partly stable.     

Psychometric properties of the Insomnia Catastrophizing Scale (ICS) in a large community sample

ABSTRACT

The purpose was to investigate the psychometric properties of the Insomnia Catastrophizing Scale (ICS) including factorial validity and internal consistency as well as discriminative and convergent validity. Associations with sleep parameters and daytime impairment are also examined. Drawn from a randomly selected sample of the general population, 1615 participants completed a survey on insomnia-related nighttime and daytime symptoms, health outcomes and psychological processes, including the ICS. A one-factor solution was supported for both the nighttime catastrophizing (11 items) and daytime catastrophizing (6 items) subscales. Both subscales displayed high internal consistencies (α > 0.90) and accounted for 59.1–70.1% of the variance. The insomnia disorder group had significantly higher scores than participants without insomnia on the two subscales and on the individual items. Cutoffs were established for both subscales with acceptable sensitivity and specificity. Both subscales displayed adequate convergent validity with measures indexing worry, cognitive pre-sleep arousal and anxiety. The two subscales were also significantly associated with nighttime and daytime insomnia symptoms. The ICS is a reliable and valid scale for the assessment of insomnia-related catastrophizing. Future research is needed to examine the test-retest reliability and treatment sensitivity of the ICS.     

Victimization and Exposure to Pro‐Self‐Harm and Pro‐Suicide Websites: A Cross‐National Study

The study of websites displaying methods of both physical self‐harm and suicide has become an important aspect of deliberate self‐injury and suicide research. However, little is known about contextual factors related to entering such sites. Using data from 3,567 respondents aged 15–30 in the US, UK, Germany, and Finland, we found that experiences of victimization are associated with entering pro‐self‐harm sites and pro‐suicide sites. Also, the victimization context had relevance, as online victimization was particularly related to pro‐self‐harm behavior. The findings suggest a need to organize more specific online support for the victims of violence and online aggression.     

Kant's Critique of Instrumental Reason

I argue against the prevalent view that in addition to the categorical imperative of morality, Kant accepts a further law of practical reason, ‘the’ Hypothetical Imperative. Kant rejects the idea that instrumental reason can be a source of a priori, objectively necessary normative requirements. His critique of instrumental reason is a central component of his argument for the supreme rational authority of morality: only moral reason can provide genuine, objective normative‐practical necessities. There are no objective practical necessities in our pursuit of empirical ends and desires. Hence, non‐moral agency is a rationally impoverished form of agency.
