    Auditory attentional selection is biased by reward cues2016Inngår i: Scientific Reports, ISSN 2045-2322, E-ISSN 2045-2322, Vol. 6, artikkel-id 36989Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Auditory attention theories suggest that humans are able to decompose the complex acoustic input into separate auditory streams, which then compete for attentional resources. How this attentional competition is influenced by motivational salience of sounds is, however, not well-understood. Here, we investigated whether a positive motivational value associated with sounds could bias the attentional selection in an auditory detection task. Participants went through a reward-learning period, where correct attentional selection of one stimulus (CS+) lead to higher rewards compared to another stimulus (CS-). We assessed the impact of reward-learning by comparing perceptual sensitivity before and after the learning period, when CS+ and CS-were presented as distractors for a different target. Performance decreased after reward-learning when CS+ was a distractor, while it increased when CS- was a distractor. Thus, the findings show that sounds that were associated with high rewards captures attention involuntarily. Additionally, when successful inhibition of a particular sound (CS-) was associated with high rewards then it became easier to ignore it. The current findings have important implications for the understanding of the organizing principles of auditory perception and provide, for the first time, clear behavioral evidence for reward-dependent attentional learning in the auditory domain in humans.

    Exposure to arousal-inducing sounds facilitates visual search2017Inngår i: Scientific Reports, ISSN 2045-2322, E-ISSN 2045-2322, Vol. 7, artikkel-id 10363Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Exposure to affective stimuli could enhance perception and facilitate attention via increasing alertness, vigilance, and by decreasing attentional thresholds. However, evidence on the impact of affective sounds on perception and attention is scant. Here, a novel aspect of affective facilitation of attention is studied: whether arousal induced by task-irrelevant auditory stimuli could modulate attention in a visual search. In two experiments, participants performed a visual search task with and without auditory-cues that preceded the search. Participants were faster in locating high-salient targets compared to low-salient targets. Critically, search times and search slopes decreased with increasing auditory-induced arousal while searching for low-salient targets. Taken together, these findings suggest that arousal induced by sounds can facilitate attention in a subsequent visual search. This novel finding provides support for the alerting function of the auditory system by showing an auditory-phasic alerting effect in visual attention. The results also indicate that stimulus arousal modulates the alerting effect. Attention and perception are our everyday tools to navigate our surrounding world and the current findings showing that affective sounds could influence visual attention provide evidence that we make use of affective information during perceptual processing.

    Auditory-Induced Emotion Mediates Perceptual Categorization of Everyday Sounds2016Inngår i: Frontiers in Psychology, ISSN 1664-1078, E-ISSN 1664-1078, Vol. 7, nr 1565Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Research has shown that emotion categorization plays an important role in perception and categorization in the visual domain. In the present paper, we investigated the role of auditory-induced emotions for auditory perception. We further investigated whether the emotional responses mediate other perceptual judgments of sounds. In an experiment, participants either rated general dissimilarities between sounds or dissimilarities of specific aspects of sounds. The results showed that the general perceptual salience map could be explained by both the emotional responses to, and perceptual aspects of, the sounds. Importantly, the perceptual aspects were mediated by emotional responses. Together these results show that emotions are an integral part of auditory perception that is used as the intuitive basis for categorizing everyday sounds.

    Affective Response Predicts Risky Choice for Fast, but Not Slow, Decisions2018Inngår i: JOURNAL OF NEUROSCIENCE PSYCHOLOGY AND ECONOMICS, ISSN 1937-321X, Vol. 11, nr 4, s. 213-227Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We use skin conductance to measure emotional arousal in subjects who make risky choices under time pressure or time delay. Our results show a strong correlation between subjects skin conductance responses and their risky choices under time pressure but not under time delay. Subjects were more risk taking for higher levels of measured electrodermal activity (skin conductance). In line with descriptive theories of risky choice, the effect was most pronounced for choices involving losses rather than gains. Taken together, our findings indicate that participants under time pressure rely on affect at the point of decision-making. This provides support for behavioral models that recognize the role of emotional brain systems in decision-making under risk.

    Variation in the mu-Opioid Receptor Gene (OPRM1) Does Not Moderate Social-Rejection Sensitivity in Humans2019Inngår i: Psychological Science, ISSN 0956-7976, E-ISSN 1467-9280, Vol. 30, nr 7, s. 1050-1062Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Given previous findings from animal studies and small-scale studies in humans, variation in the mu-opioid receptor gene (OPRM1) has been proposed as a strong biological candidate for moderating sensitivity to social rejection. Using a substantially larger sample (N = 490) than previous studies, a prospective genotyping strategy, and preregistered analysis plans, we tested the hypotheses that OPRM1 variation measured by the functional A118G polymorphism (rs1799971) moderates (a) dispositional sensitivity to rejection and feelings of distress following social exclusion and (b) decision making involving social cognition. In three experimental tasks commonly used to assess altruism, reciprocity, and trust in humans, we found no evidence in favor of the hypotheses; nine main tests were preregistered, and all of them yielded small and statistically insignificant estimates. In secondary analyses, we used Bayesian inference and estimation to quantify support for our findings. Taken together, our results strongly suggest that the link between OPRM1 A118G variation and social-rejection sensitivity is weaker than previously thought.

    The Arithmetic of Emotion: Integration of Incidental and Integral Affect in Judgments and Decisions2016Inngår i: Frontiers in Psychology, ISSN 1664-1078, E-ISSN 1664-1078, Vol. 7, s. 325-Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    Research has demonstrated that two types of affect have an influence on judgment and decision making: incidental affect (affect unrelated to a judgment or decision such as a mood) and integral affect (affect that is part of the perceiver’s internal representation of the option or target under consideration). So far, these two lines of research have seldom crossed so that knowledge concerning their combined effects is largely missing. To fill this gap, the present review highlights differences and similarities between integral and incidental affect. Further, common and unique mechanisms that enable these two types of affect to influence judgment and choices are identified. Finally, some basic principles for affect integration when the two sources co-occur are outlined. These mechanisms are discussed in relation to existing work that has focused on incidental or integral affect but not both.
