Validation of the Short Version (TLS-15) of the Triangular Love Scale (TLS-45) across 37 Languages.

Love is a phenomenon that occurs across the world and affects many aspects of human life, including the choice of, and process of bonding with, a romantic partner. Thus, developing a reliable and valid measure of love experiences is crucial. One of the most popular tools to quantify love is Sternberg's 45-item Triangular Love Scale (TLS-45), which measures three love components: intimacy, passion, and commitment. However, our literature review reveals that most studies (64%) use a broad variety of shortened versions of the TLS-45. Here, aiming to achieve scientific consensus and improve the reliability, comparability, and generalizability of results across studies, we developed a short version of the scale-the TLS-15-comprised of 15 items with 5-point, rather than 9-point, response scales. In Study 1 (N = 7,332), we re-analyzed secondary data from a large-scale multinational study that validated the original TLS-45 to establish whether the scale could be truncated. In Study 2 (N = 307), we provided evidence for the three-factor structure of the TLS-15 and its reliability. Study 3 (N = 413) confirmed convergent validity and test-retest stability of the TLS-15. Study 4 (N = 60,311) presented a large-scale validation across 37 linguistic versions of the TLS-15 on a cross-cultural sample spanning every continent of the globe. The overall results provide support for the reliability, validity, and cross-cultural invariance of the TLS-15, which can be used as a measure of love components-either separately or jointly as a three-factor measure.

Halo It's Meat! the Effect of the Vegetarian Label on Calorie Perception and Food Choices.

In the last few years, vegetarian products have become a widespread dietary option in food industry to the point that large retail chains such as McDonald's has offered a vegetarian burger to their customers (e.g., the Grand Veggie). In the present research, two studies investigated the influence of a vegetarian label on calorie perception, frequency consumption and food choices. In the first study (N = 211) participants were randomly assigned to an experimental design 2 (burger type: Grand Veggie vs Big Mac). In the second study (N = 915), participants were either exposed to a similar burger labeled vegetarian or a meat-based. Both studies show that vegetarian products are perceived as being less caloric than their non-vegetarian equivalents. However, participants do not report more intention to eat more vegetarian products and do not lead to differences in menu composition.

The calories underestimation of "organic" food: Exploring the impact of implicit evaluations.

Specific attributes of a food product can cause it to be spontaneously but wrongly perceived as healthier than it really is (i.e., the health halo effect). Notably, there is preliminary evidence that individuals evaluate organic food as less caloric than regular, non-organic food. However, explanations regarding the cognitive mechanisms underlying the health halo effect remain scarce. Drawing from the implicit cognition literature, we hypothesize that this effect could be due to (a) the reactivation in memory of implicit positive evaluations and/or (b) the reactivation of a semantic association between the concepts "organic" and "non-caloric". We first conducted a 2 (Product label: organic versus non-organic) × continuous (Valence-IAT score) × continuous (Calorie-IAT score) study (N = 151) to test these hypotheses, and conducted a conceptual replication in a second study (N = 269). We computed Bayesian analyses alongside frequentist analyses in order to test for potential null hypotheses, as well as frequencies and Bayesian meta-regression including both datasets. Both methods provided consistent results. First, Bayesian analyses yielded extremely strong evidence in favor of the hypothesis that the organic label leads to an underestimation of caloric value. Second, they provided strong evidence that this effect is not moderated by implicit evaluations. Hence, we replicated the organic halo effect but showed that, surprisingly, it does not arise from implicit associations. We discuss these findings and propose directions for future research regarding the mechanisms underlying calories (under)estimation.

Emotional labor: The role of organizational dehumanization.

In a permanent quest for profit, employees can be reduced to a mere function or instrument, dissociated from their quality as individuals for the organization's ends. Experiencing such a feeling as an employee has been called organizational dehumanization. Scholars have recently suggested that organizational dehumanization may play a key role in the development of emotional labor. However, how organizational dehumanization and two main emotional labor strategies (i.e., surface and deep acting) are causally related remains unclear in this literature. In the present research, we argue that employees who experience organizational dehumanization and whose self is thus threatened then engage in surface acting to "conserve" their self or in deep acting to "give up" their self in service of the role. Overall, the combined results of three studies offer strong evidence that organizational dehumanization leads employees to perform more surface acting, but not more deep acting. Unexpectedly, our findings also indicate that deep acting reduces the perception of being dehumanized by the organization. In showing this, the present research sheds light on the potential dark side of deep acting, by suggesting that this strategy can change employees' perspectives in a way that may encourage them to stay in an organization that treats them as a means to an end.

Authoritarian attitudes are associated with higher autonomic reactivity to stress and lower recovery.

Right-wing authoritarianism (RWA) and social dominance orientation (SDO) both predict generalized prejudice, dehumanization, intergroup discrimination, oppression, violence, right-wing political party preference, and generally punitive attitudes. Authoritarian attitudes have been theorized to involve maladaptive emotional, cognitive, and social self-regulation. However, there is no study of authoritarianism using the functioning of the parasympathetic nervous system (PNS) as a physiological index of self-regulation, thus leaving it unclear whether regulation is "impaired" with authoritarian attitudes per se. PNS functioning is commonly assessed by examining tonic and phasic heart rate variability (HRV). These two components are recognized to be important in terms of adaptation to stress. Decreased HRV has been associated with hypoactive prefrontal regulation, hyperactive subcortical structures, maladaptive self-regulation, hyper-vigilance, decreased prosocial tendencies, defensiveness, impulsive behaviors, and aggression. Previous research suggests that self-regulatory failure may favor hostile attitudes and prejudicial intergroup behaviors. In a first study, we found that high RWA was associated with lower tonic HRV at rest. In a second study, stress-induced autonomic reactivity and poststress autonomic recovery were examined as potential pathways linking authoritarian attitudes to self-regulation. We found that high RWA and high SDO were associated with (i) lower tonic HRV during stress, (ii) greater autonomic reactivity during stress, and (iii) lower autonomic recovery. Overall, our results suggest that autonomic dysregulation during and following stress is a plausible physiological pathway connecting RWA and SDO to self-regulation. Implications of such results for research on political attitudes are discussed. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
