OXTR rs53576 genotype and gender predict trait gratitude

Abstract

Dispositional gratitude was investigated in 190 (96 M, 94 F) participants with saliva samples genotyped for the oxytocin receptor gene single nucleotide polymorphism (SNP) rs53576 (112 A-carriers, 78 GGs). Trait gratitude was measured using the Gratitude Questionnaire-6 (GQ-6), and trait empathy was assessed with the Interpersonal Reactivity Index (IRI Perspective Taking and Empathic Concern). Due to non-normal distributions of the GQ-6 by SNP group and by gender, non-parametric analyses using simulations and bootstrap 95% CIs were conducted. Results show main effects of SNP group (with GGs scoring higher than A-carriers) and gender (with females scoring higher than males) on trait gratitude. Given the associations of both the OXTR SNP rs53576 and gender with empathy, and the prosocial associations of trait empathy and gratitude, we tested an indirect effects model using PROCESS. Results showed that both SNP group and gender had an indirect effect on trait gratitude through trait empathy.     

More gratitude,less materialism: The mediating role of life satisfaction

An empirical relationship has been documented between gratitude and materialism, such that stronger feelings of gratitude are associated with lower materialism. Building on Fredrickson's (1998, 2001) theory that positive emotions ‘broaden’ and ‘build’ we sought to expand upon this finding by (1) examining satisfaction with life as a potential mechanism for this relationship, and (2) exploring the causal direction of this relationship through experimental means. Study 1 (n = 131) demonstrated that satisfaction with life mediated the relationship between gratitude and materialism. Study 2 (n = 171) showed that that experimentally induced gratitude resulted in higher satisfaction with life and lower materialism in a high gratitude condition compared to an envy (low gratitude) condition. Implications and directions for future research were discussed.     

Speaking of pain in Greek: Implications for the cognitive permeation of emotions

ABSTRACT

Although item-memory for emotional information is enhanced, memory for associations between items is often impaired for negative, emotionally arousing compared to neutral information. We tested two possible mechanisms underlying this impairment, using picture pairs: 1) higher confidence in one’s own ability to memorise negative information may cause participants to under-study negative pairs; 2) better interactive imagery for neutral pairs could facilitate associative memory for neutral pairs more than for negative pairs. Tested with associative recognition, we replicated the impairment of associative memory for negative pairs. We also replicated the result that confidence in future memory (judgments of learning) was higher for negative than neutral pairs. Inflated confidence could not explain the impairment of associative recognition memory: Judgements of learning were positively correlated with associative memory success for both negative and neutral pairs. However, neutral pairs were rated higher in their conduciveness to interactive imagery than negative pairs, and this difference in interactive imagery showed a robust relationship to the associative memory difference. Thus, associative memory reductions for negative information are not due to differences in encoding effort. Instead, interactive imagery may be less effective for encoding of negative than neutral pairs.     

Routine cognitive errors: A trait-like predictor of individual differences in anxiety and distress

Five studies (N=361) sought to model a class of errors—namely, those in routine tasks—that several literatures have suggested may predispose individuals to higher levels of emotional distress. Individual differences in error frequency were assessed in choice reaction-time tasks of a routine cognitive type. In Study 1, it was found that tendencies toward error in such tasks exhibit trait-like stability over time. In Study 3, it was found that tendencies toward error exhibit trait-like consistency across different tasks. Higher error frequency, in turn, predicted higher levels of negative affect, general distress symptoms, displayed levels of negative emotion during an interview, and momentary experiences of negative emotion in daily life (Studies 2–5). In all cases, such predictive relations remained significant with individual differences in neuroticism controlled. The results thus converge on the idea that error frequency in simple cognitive tasks is a significant and consequential predictor of emotional distress in everyday life. The results are novel, but discussed within the context of the wider literatures that informed them.     

Development and validation of a facial expression database based on the dimensional and categorical model of emotions

ABSTRACT

The present study describes the development and validation of a facial expression database comprising five different horizontal face angles in dynamic and static presentations. The database includes twelve expression types portrayed by eight Japanese models. This database was inspired by the dimensional and categorical model of emotions: surprise, fear, sadness, anger with open mouth, anger with closed mouth, disgust with open mouth, disgust with closed mouth, excitement, happiness, relaxation, sleepiness, and neutral (static only). The expressions were validated using emotion classification and Affect Grid rating tasks [Russell, Weiss, & Mendelsohn, 1989. Affect Grid: A single-item scale of pleasure and arousal. Journal of Personality and Social Psychology, 57(3), 493–502]. The results indicate that most of the expressions were recognised as the intended emotions and could systematically represent affective valence and arousal. Furthermore, face angle and facial motion information influenced emotion classification and valence and arousal ratings. Our database will be available online at the following URL. https://www.dh.aist.go.jp/database/face2017/.     

The impact of emotional faces on younger and older adults’ attentional blink

ABSTRACT

The attentional blink (AB) is the impaired ability to detect a second target (T2) when it follows shortly after the first (T1) among distractors in a rapid serial visual presentation (RSVP). Given questions about the automaticity of age differences in emotion processing, the current study examined whether emotion cues differentially impact the AB elicited in older and younger adults. Twenty-two younger (18–22 years) and 22 older adult participants (62–78 years) reported on the emotional content of target face stimulus pairs embedded in a RSVP of scrambled-face distractor images. Target pairs included photo-realistic faces of angry, happy, and neutral expressions. The order of emotional and neutral stimuli as T1 or T2 and the degree of temporal separation within the RSVP systematically varied. Target detection accuracy was used to operationalise the AB. Although older adults displayed a larger AB than younger adults, no age differences emerged in the impact of emotion on the AB. Angry T1 faces increased the AB of both age groups. Neither emotional T2 attenuated the AB. Negative facial expressions held the attention of younger and older adults in a comparable manner, exacerbating the AB and supporting a negativity bias instead of a positivity effect in older adults.     

Oh,the things you don’t know: awe promotes awareness of knowledge gaps and science interest

ABSTRACT

Awe is described as an a “epistemic emotion” because it is hypothesised to make gaps in one’s knowledge salient. However, no empirical evidence for this yet exists. Awe is also hypothesised to be an antecedent to interest in science because science is one way to fill those knowledge gaps. Results from four pre-registered studies (N?=?1518) indicate that manipulating awe through online (Studies 1a, 1b, and 1c) and virtual reality (Study 2) videos, led to greater awareness of knowledge gaps. Awareness of knowledge gaps was consistently associated with greater science interest and to choosing tickets to a science museum over tickets to an art museum (Study 1b). These effects were not consistently observed on, nor moderated by, other measures related to cognition, religion, and spirituality. However, exploratory analyses showed that science interest was better predicted by positive emotions than by awe. Still, these results provide the first empirical evidence of awe as an “epistemic emotion” by demonstrating its effects on awareness of knowledge gaps. These findings are also extended to the effects of awe on science interest as one possible outcome of awareness of knowledge gaps.     

State emotional clarity and attention to emotion: a naturalistic examination of their associations with each other,affect, and context

ABSTRACT

Despite emotional clarity and attention to emotion being dynamic in nature, research has largely focused on their trait forms. We examined the association between state and trait forms of these two constructs, and how they are related to affect intensity and two contextual variables: Social context and significant event occurrence. Seventy-nine adults recruited from the community reported eight times a day for a week on the extent to which they were clear about their emotions, attended to their emotions, levels of affect intensity, the number of people with whom they were interacting, and whether a significant event had occurred. State clarity and attention were positively associated, demonstrating a moderate relation similar to that of their trait forms. Trait and state attention, but not trait and state clarity, were significantly positively associated. Positive and negative affect were quadratically associated with clarity and attention, with the highest levels of affect intensity reported at high levels of clarity and attention. Clarity and attention were positively associated with increasing numbers of people with whom people were interacting. Attention and clarity were elevated when significant events occurred – especially during positive events. We discuss the findings in the context of functional adaptation theories of emotion.     

Automatic control of negative emotions: Evidence that structured practice increases the efficiency of emotion regulation

Emotion regulation (ER) is vital to everyday functioning. However, the effortful nature of many forms of ER may lead to regulation being inefficient and potentially ineffective. The present research examined whether structured practice could increase the efficiency of ER. During three training sessions, comprising a total of 150 training trials, participants were presented with negatively valenced images and asked either to “attend” (control condition) or “reappraise” (ER condition). A further group of participants did not participate in training but only completed follow-up measures. Practice increased the efficiency of ER as indexed by decreased time required to regulate emotions and increased heart rate variability (HRV). Furthermore, participants in the ER condition spontaneously regulated their negative emotions two weeks later and reported being more habitual in their use of ER. These findings indicate that structured practice can facilitate the automatic control of negative emotions and that these effects persist beyond training.
