Duration perception of emotional stimuli: Using evaluative conditioning to avoid sensory confounds

It has been found that emotional pictures are estimated to last longer than neutral ones. However, emotional and neutral stimuli often differ in their physical characteristics, too. Since this might also affect time perception, we present a method disentangling a possible confounding regarding the processing of physically different stimulus material. In the evaluative condition paradigm, participants, at first, learnt the association of neutral images with a certain Landolt ring and of emotional images with another Landolt ring with a different gap position. The conditioned Landolt rings were subsequently used in a temporal bisection task. In two experiments, the results revealed a temporal overestimation of Landolt rings conditioned with emotional pictures compared to neutral pictures showing that the temporal overestimation of emotional stimuli cannot be attributed to perceptual differences between neutral and emotional stimuli. The method provides the potential for investigating emotional effects on various perceptual processes.     

Revisiting the relation between contingency awareness and attention: Evaluative conditioning relies on a contingency focus

Although evaluative conditioning has occasionally been demonstrated in the absence of contingency awareness, many recent studies imply that its acquisition depends on the availability of attentional resources during conditioning. In previous experiments attention has typically been manipulated in a general way rather than looking at the particular focus of attention. The present study investigated the role of a focus on the CS–US contingency. Two separate distraction tasks were designed that either diverted attention from the stimuli or directed it to the stimuli while drawing attention away from the contingency between the stimuli. Both types of distraction were shown to eliminate evaluative conditioning. Significant evaluative conditioning was observed in a third group of participants who were required to attend the contingencies. A mediation analysis showed that the observed discrepancy in evaluative conditioning effects between groups was mediated by contingency awareness. The results imply that attention in terms of a stimulus focus is not sufficient for evaluative conditioning to occur. Rather, attention to the contingencies between stimuli appears to be crucial in evaluative conditioning, because it is supposed to foster the acquisition of contingency awareness.     

The impact of open and closed mindsets on evaluative priming

In the present research, we argue that open versus closed mindsets, accompanying ongoing versus completed mental jobs on the prime, determine the size of congruity effects in the evaluative priming paradigm. More specifically, we hypothesised that disfluent primes that resist an easily completed encoding process should induce an open mindset and thereby result in stronger congruity effects than fluent primes that induce closed mindsets. Across two experiments, we applied two different manipulations of prime fluency: gradual demasking (Experiment 1) and colour contrast (Experiment 2). As expected, in both experiments we found robust congruity effects, but only on trials with disfluent (vs. fluent) primes. Results of a follow-up experiment suggest that these effects are not due to attentional processes. We conclude that the mindsets resulting from individuals' activities during encoding are crucial in determining the outcome of evaluative priming effects.     

Is evaluative conditioning really resistant to extinction? Evidence for changes in evaluative judgements without changes in evaluative representations

Evaluative conditioning (EC) is defined as the change in the evaluation of a conditioned stimulus (CS) due to its pairing with a positive or negative unconditioned stimulus (US). Although several individual studies suggest that EC is unaffected by unreinforced presentations of the CS without the US, a recent meta-analysis indicates that EC effects are less pronounced for post-extinction measurements than post-acquisition measurements. The disparity in research findings suggests that extinction of EC may depend on yet unidentified conditions. In an attempt to uncover these conditions, three experiments (N = 784) investigated the influence of unreinforced post-acquisition CS presentations on EC effects resulting from simultaneous versus sequential pairings and pairings with single versus multiple USs. For all four types of CS–US pairings, EC effects on self-reported evaluations were reduced by unreinforced CS presentations, but only when the CSs had been rated after the initial presentation of CS–US pairings. EC effects on an evaluative priming measure remained unaffected by unreinforced CS presentations regardless of whether the CSs had been rated after acquisition. The results suggest that reduced EC effects resulting from unreinforced CS presentations are due to judgement-related processes during the verbal expression of CS evaluations rather than genuine changes in the underlying evaluative representations.     

Emotional intelligence and resilience

This study examined the relationship between emotional intelligence (EI) and the stress process. Participants (N = 126) completed an ability-based measure of EI and then engaged with two stressors. We assessed stressor appraisals, emotions, and physiological stress responses over time. We expected that higher EI would facilitate stress responses in the direction of challenge, rather than threat. As expected, EI facets were related to lower threat appraisals, more modest declines in positive affect, less negative affect and challenge physiological responses to stress. However, findings differed for men and women. This study provides predictive validity that EI facilitates stress resilience.     

Eye'm lovin' it! The role of gazing awareness in mimetic desires

Recent studies showed that people evaluate objects more favorably when these objects are gazed-at by others, an effect coined as “mimetic desire”. In two studies, we tested whether mimetic desire stems from an automatic form of learning by examining one dimension of automaticity, i.e., people's awareness of the object-gaze association. Participants saw 6 neutral art paintings associated with a female gazing toward two of the paintings, away from two of the paintings, and closing her eyes with respect to the last two paintings. After the exposition phase, participants evaluated the paintings and performed a contingency-awareness test. Importantly, participants' responses on this test were genuinely driven by memory and not by inferences from liking. Results show that participants preferred objects that were gazed-at but only when they were aware of the object-gaze association. Hence, despite the adaptive function of joint attention, its impact on valence acquisition does not seem to qualify as an implicit learning process.     

Implicit and explicit emotional behavior and mindfulness

The objective of this study was to examine whether the “step back and watch” attitude of mindfulness manifests in less emotional behavior. We hypothesized that the “acceptance” facet of mindfulness, but not the “presence” facet, is negatively associated with the magnitude of emotional behavior in four tests, i.e., (1) rating of words, (2) rating of aversive and neutral pictures, and (3) evaluative conditioning (EC). Additionally, we hypothesized that (4) the acceptance facet is associated with increased reaction time (RT) in an emotional Stroop test, and that the presence facet is associated with decreased RT and lower error rate. The sample consisted of N = 247 non-clinical adults and was tested in a cross-sectional study. The results provide partial evidence that the acceptance facet of mindfulness may be associated with less aversive reactions towards aversive stimuli. Future studies should substantiate these findings but also determine their clinical relevance.     

Contagious resource depletion and anxiety? Spreading effects of evaluative concern and impression formation in dyadic social interaction

Two studies examined how adopting an impression formation or evaluative concern mindset affects individuals' own and their interaction partner's experience of potentially stressful social exchanges, such as first meeting situations and interethnic interaction. Our main hypothesis was that adopting an impression formation mindset would, by diverting individuals' focus away from themselves and toward others, reduce both their own and their partner's cognitive resource depletion and negative affect. Consistent with predictions, positive effects of impression formation were evident and were “contagious” in that they were evident across individuals who received the mindset instructions and their partners, who were unaware of the manipulation. The positive effects of impression formation instructions were generally evident both in comparison to evaluative concern instructions, which provided similar structure, and in comparison to no instructions at all. Thus, adopting an impression formation mindset seems an effective strategy for minimizing negative outcomes experienced in stressful social interactions.
