The effect of acute pain on risky and intertemporal choice

Pain is a highly salient and attention-demanding experience that motivates people to act. We investigated the effect of pain on decision making by delivering acute thermal pain to participants' forearm while they made risky and intertemporal choices involving money. Participants (n = 107) were more risk seeking under pain than in a no-pain control condition when decisions involved gains but not when they involved equivalent losses. Pain also resulted in greater preference for immediate (smaller) over future (larger) monetary rewards. We interpret these results as a motivation to offset the aversive, pain-induced state, where monetary rewards become more appealing under pain than under no pain and when delivered sooner rather than later. Our findings add to the long-standing debate regarding the role of intuition and reflection in decision making.

Auditory attentional selection is biased by reward cues

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.

An Experimental Field Study of the Effects of Listening to Self-selected Music on Emotions, Stress, and Cortisol Levels

Music listening may evoke meaningful emotions in listeners and may enhance certain health benefits. At the same time, it is important to consider individual differences, such as musical taste, when examining musical emotions and in considering their possible health effects. In a field experiment, 21 women listened to their own preferred music on mp3-players daily for 30 minutes during a two week time  period in their own homes. One week they listened to their own chosen relaxing music and the other their own chosen energizing music. Self-reported stress, emotions and health were measured by a questionnaire each day and salivary cortisol was measured with 6 samples two consecutive days every week. The experiment group was compared to a control group (N = 20) who were instructed to relax for 30 minutes everyday for three weeks, and with a baseline week when they relaxed without music for one week (before the music intervention weeks). The results showed that when participants in the experiment group listened to their own chosen music they reported to have experienced significantly higher intensity positive emotions and less stress than when they relaxed without music. There was also a significant decrease in cortisol from the baseline week to the second music intervention week. The control group’s reported stress levels, perceived emotions and cortisol levels remain stable during all three weeks of the study. Together these results suggest that listening to preferred music may be a more effective way of reducing feelings of stress and cortisol levels and increasing positive emotions than relaxing without music.  Keywords: music, emotions, stress, cortisol levelsSpanishEstudio experimental de Campo de los efectos de la Escucha de Musica seleccionada por uno mismo en las emociones, el stress y los niveles de cortisol.Marie Helsing, Daniel Västfjäll, Pär Bjälkebring, Patrik Juslin, Terry Hartig  La escucha musical puede evocar emociones significativas en los oyentes y puede lograr algunos beneficios en la salud. Al mismo tiempo, es importante considerar las diferencias individuales, como por ejemplo el gusto musical, cuando examinamos las emociones musicales y al considerar sus posibles efectos en la salud. En este experimento de campo 21 mujeres escucharon su música preferida 30 minutos por dia durante 2 semanas utilizando reproductores de mp3 en sus propias casas. Una semana escucharon la música que eligieron como relajante y la semana siguiente la música que eligieron como energizante. Los auto-reportes de stress, emociones y salud fueron medidos con cuestionarios diarios a la vez que se midió el nivel de cortisol en saliva con 6 muestras tomadas durante dos días consecutivos cada semana. El grupo experimental fue comparado con el grupo control (N=20) que habían sido instruidas para realizar relajación durante 30 minutos todos los días durante tres semanas y con una semana de base en la cual se relajaban sin música (antes de las semanas de intervención musical). Los resultados mostraron que cuando las  participantes del grupo experimental escucharon su propia música, reportaron haber experimentado significativamente una mayor intensidad de emociones positivas y menor stress que cuando se relajaron sin música. Hubo también una disminución significativa en el cortisol desde la semana de base  a la segunda semana con la intervención musical. El grupo control reportó que los niveles de stress , percepción emocional y niveles de cortisol permanecieron estables durante las tres semanas del estudio. Estos resultados sugieren que escuchar música preferida puede ser una forma más efectiva de reducir la sensación de stress y los niveles de cortisol y de incrementar las emociones positivas que la relajación sin música. Palabras clave: Escucha musical , cortisol , respuesta al stress GermanDie Effekte vom Hören selbst gewählter Musik auf Emotionen, Stress und Cortisol Level:  Eine experimentelle Feldstudie Marie Helsing, Daniel Västfjäll, Pär Bjälkebring, Patrik Juslin, Terry Hartig Musikhören kann beim Hörer bedeutsame Emotionen auslösen und gewisse Gesundheitsvorteile bewirken.

Selbstberichteter Stress, Emotionenund Gesundheit wurden mithilfe eines Fragebogens täglich, der Cortisolspiegel mit 6 Beispielen an zwei aufeinander folgenden Tagen wöchentlich gemessen. Die experimentelle Gruppe wurde mit einer Kontrollgruppe verglichen (N=20), die angewiesen wurde, 3 Wochen lang täglich 30 Minuten zu entspannen; mit einer baseline-Woche, während der sie eine Woche lang ohne Musik entspannten (vor der Musik-Interventionswoche). Die Ergebnisse zeigten, dass die Teilnehmer der experimentellen Gruppe berichteten, sie hätten bei ihrer selbst gewählten Musik signifikant höhere intensive positive Emotionen und weniger Stress, als wenn sie ohne Musik entspannten. Außerdem fand sich eine signifikante Abnahme des Cortisols von der baseline-Woche zur 2. Woche mit Musikintervention. Die von der Kontrollgruppe berichteten Stresslevel, erlebten Emotionen und der Cortisolspiegel blieben während all der drei Studienwochen stabil.

Stress, emozioni e salute sono stati misurati da un questionario ogni giorno e il cortisolo della salia è stato misurato con 6 campioni due giorni consecutivi ogni settimana. Il gruppo di sperimentazione è stato messo a confroto con un altro gruppo di controllo (N= 20) al quale è stata assegnata una settimana di controllo di relax senza musica e dopo hanno avuto istruzione di rilassarsi per 30 minuti ogni giorno per tre settimane. I risultati hanno mostrato che quando i partecipanti del gruppo hanno ascoltato la loro musica essi hanno riferito di aver avuto meno stress e di aver vissuto emozioni positive in un livello significativamente piú alto rispetto a quando si rilassavano senza musica. C’è stata anche una diminuzine significativa del cortisolo nel passaggio tra la settimana di controllo alla settimana in cui è stata introdotta la musica.

Intuition and Moral Decision-Making - The Effect of Time Pressure and Cognitive Load on Moral Judgment and Altruistic Behavior

Do individuals intuitively favor certain moral actions over others? This study explores the role of intuitive thinking-induced by time pressure and cognitive load-in moral judgment and behavior. We conduct experiments in three different countries (Sweden, Austria, and the United States) involving over 1,400 subjects. All subjects responded to four trolley type dilemmas and four dictator games involving different charitable causes. Decisions were made under time pressure/time delay or while experiencing cognitive load or control. Overall we find converging evidence that intuitive states do not influence moral decisions. Neither time-pressure nor cognitive load had any effect on moral judgments or altruistic behavior. Thus we find no supporting evidence for the claim that intuitive moral judgments and dictator game giving differ from more reflectively taken decisions. Across all samples and decision tasks men were more likely to make utilitarian moral judgments and act selfishly compared to women, providing further evidence that there are robust gender differences in moral decision-making. However, there were no significant interactions between gender and the treatment manipulations of intuitive versus reflective decision-making.

Anticipated Guilt for Not Helping and Anticipated Warm Glow for Helping Are Differently Impacted by Personal Responsibility to Help

One important motivation for people behaving prosocially is that they want to avoid negative and obtain positive emotions. In the prosocial behavior literature however, the motivations to avoid negative emotions (e.g., guilt) and to approach positive emotions (e.g., warm glow) are rarely separated, and sometimes even aggregated into a single mood-management construct. The aim of this study was to investigate whether anticipated guilt if not helping and anticipated warm glow if helping are influenced similarly or differently when varying situational factors related to personal responsibility to help. Helping scenarios were created and pilot tests established that each helping scenario could be formulated both in a high-responsibility version and in a low-responsibility version. In Study 1 participants read high-responsibility and low-responsibility helping scenarios, and rated either their anticipated guilt if not helping or their anticipated warm glow if helping (i.e., separate evaluation). Study 2 was similar but here participants rated both their anticipated guilt if not helping and their anticipated warm glow if helping (i.e., joint evaluation). Anticipated guilt was clearly higher in the high-responsibility versions, but anticipated warm glow was unaffected (in Studies 1a and 1b), or even higher in the low-responsibility versions (Study 2). In Studies 3 (where anticipated guilt and warm glow were evaluated separately) and 4 (where they were evaluated jointly), personal responsibility to help was manipulated within-subjects. Anticipated guilt was again constantly higher in the high-responsibility versions but for many types of responsibility-manipulations, anticipated warm glow was higher in the low-responsibility versions. The results suggest that we anticipate guilt if not fulfilling our responsibility but that we anticipate warm glow primarily when doing over and beyond our responsibility. We argue that future studies investigating motivations for helping should measure both anticipated negative consequences for oneself if not helping, and anticipated positive consequences for oneself if helping.

Auditory-Induced Emotion Mediates Perceptual Categorization of Everyday Sounds

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.

Adult Age Differences in Dual Information Processes: Implications for the Role of Affective and Deliberative Processes in Older Adults' Decision Making

Age differences in affective/experiential and deliberative processes have important theoretical implications for judgment and decision theory and important pragmatic implications for older-adult decision making. Age-related declines in the efficiency of deliberative processes predict poorer-quality decisions as we age. However, age-related adaptive processes, including motivated selectivity in the use of deliberative capacity, an increased focus on emotional goals, and greater experience, predict better or worse decisions for older adults depending on the situation. The aim of the current review is to examine adult age differences in affective and deliberative information processes in order to understand their potential impact on judgments and decisions. We review evidence for the role of these dual processes in judgment and decision making and then review two representative life-span perspectives (based on aging-related changes to cognitive or motivational processes) on the interplay between these processes. We present relevant predictions for older-adult decisions and make note of contradictions and gaps that currently exist in the literature. Finally, we review the sparse evidence about age differences in decision making and how theories and findings regarding dual processes could be applied to decision theory and decision aiding. In particular, we focus on prospect theory ( Kahneman & Tversky, 1979 ) and how prospect theory and theories regarding age differences in information processing can inform one another.

Greater Emotional Gain from Giving in Older Adults: Age-Related Positivity Bias in Charitable Giving

Older adults have been shown to avoid negative and prefer positive information to a higher extent than younger adults. This positivity bias influences their information processing as well as decision-making. We investigate age-related positivity bias in charitable giving in two studies. In Study 1 we examine motivational factors in monetary donations, while Study 2 focuses on the emotional effect of actual monetary donations. In Study 1, participants (n = 353, age range 20-74 years) were asked to rate their affect toward a person in need and then state how much money they would be willing to donate to help this person. In Study 2, participants (n = 108, age range 19-89) were asked to rate their affect toward a donation made a few days prior. Regression analysis was used to investigate whether or not the positivity bias influences the relationship between affect and donations. In Study 1, we found that older adults felt more sympathy and compassion and were less motivated by negative affect when compared to younger adults, who were motivated by both negative and positive affect. In Study 2, we found that the level of positive emotional reactions from monetary donations was higher in older participants compared to younger participants. We find support for an age-related positivity bias in charitable giving. This is true for motivation to make a future donation, as well as affective thinking about a previous donation. We conclude that older adults draw more positive affect from both the planning and outcome of monetary donations and hence benefit more from engaging in monetary charity than their younger counterparts.

The Arithmetic of Emotion: Integration of Incidental and Integral Affect in Judgments and Decisions

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.

Regulation of experienced and anticipated regret in daily decision making

Decisions were sampled from 108 participants during 8 days using a web-based diary method. Each day participants rated experienced regret for a decision made, as well as forecasted regret for a decision to be made. Participants also indicated to what extent they used different strategies to prevent or regulate regret. Participants regretted 30% of decisions and forecasted regret in 70% of future decisions, indicating both that regret is relatively prevalent in daily decisions but also that experienced regret was less frequent than forecasted regret. In addition, a number of decision-specific regulation and prevention strategies were successfully used by the participants to minimize regret and negative emotions in daily decision making. Overall, these results suggest that regulation and prevention of regret are important strategies in many of our daily decisions.

Scope insensitivity in helping decisions: Is it a matter of culture and values?

The singularity effect of identifiable victims refers to people's greater willingness to help a single concrete victim compared with a group of victims experiencing the same need. We present 3 studies exploring values and cultural sources of this effect. In the first study, the singularity effect was found only among Western Israelis and not among Bedouin participants (a more collectivist group). In Study 2, individuals with higher collectivist values were more likely to contribute to a group of victims. Finally, the third study demonstrates a more causal relationship between collectivist values and the singularity effect by showing that enhancing people's collectivist values using a priming manipulation produces similar donations to single victims and groups. Moreover, participants' collectivist preferences mediated the interaction between the priming conditions and singularity of the recipient. Implications for several areas of psychology and ways to enhance caring for groups in need are discussed.

Happiness and arousal: framing happiness as arousing results in lower happiness ratings for older adults

Older adults have been shown to describe their happiness as lower in arousal when compared to younger adults. In addition, older adults prefer low arousal positive emotions over high arousal positive emotions in their daily lives. We experimentally investigated whether or not changing a few words in the description of happiness could influence a person’s rating of their happiness. We randomly assigned 193 participants, aged 22–92 years, to one of three conditions (high arousal, low arousal, or control). In line with previous findings, we found that older participants rated their happiness lower when framed as high in arousal (i.e., ecstatic, to be bursting with positive emotions) and rated their happiness higher when framed as low in arousal (i.e., satisfied, to have a life filled with positive emotions). Younger adults remained uninfluenced by the manipulation. Our study demonstrates that arousal is essential to understanding ratings of happiness, and gives support to the notion that there are age differences in the preference for arousal.

Pseudoinefficacy: negative feelings from children who cannot be helped reduce warm glow for children who can be helped

In a great many situations where we are asked to aid persons whose lives are endangered, we are not able to help everyone. What are the emotional and motivational consequences of "not helping all"? In a series of experiments, we demonstrate that negative affect arising from children that could not be helped decreases the warm glow of positive feeling associated with aiding the children who can be helped. This demotivation from the children outside of our reach may be a form of "pseudoinefficacy" that is non-rational. We should not be deterred from helping whomever we can because there are others we are not able to help.

Negative emotion provides cues for orienting auditory spatial attention

The auditory stimuli provide information about the objects and events around us. They can also carry biologically significant emotional information (such as unseen dangers and conspecific vocalizations), which provides cues for allocation of attention and mental resources. Here, we investigated whether task-irrelevant auditory emotional information can provide cues for orientation of auditory spatial attention. We employed a covert spatial orienting task: the dot-probe task. In each trial, two task-irrelevant auditory cues were simultaneously presented at two separate locations (left-right or front-back). Environmental sounds were selected to form emotional vs. neutral, emotional vs. emotional, and neutral vs. neutral cue pairs. The participants' task was to detect the location of an acoustic target that was presented immediately after the task-irrelevant auditory cues. The target was presented at the same location as one of the auditory cues. The results indicated that participants were significantly faster to locate the target when it replaced the negative cue compared to when it replaced the neutral cue. The positive cues did not produce a clear attentional bias. Further, same valence pairs (emotional-emotional or neutral-neutral) did not modulate reaction times due to a lack of spatial attention capture by one cue in the pair. Taken together, the results indicate that negative affect can provide cues for the orientation of spatial attention in the auditory domain.

Attentional and emotional prioritization of the sounds occurring outside the visual field

The ability to detect and localize sounds in an environment is critical for survival. Localizing sound sources is a computational challenge for the human brain because the auditory cortex seems to lack a topographical space representation. However, attention and task demands can modulate localization performance. Here, we investigated whether the localization performance for sounds occurring directly in front of or behind people could be modulated by emotional salience and sound-source location. We measured auditory-induced emotion by ecological sounds occurring in the frontal or rear perceptual fields, and employed a speeded localization task. The results showed that both localization speed and accuracy were higher, and that stronger negative emotions were induced when sound sources were behind the participants. Our results provide clear behavioral evidence that auditory attention can be influenced by sound-source location. Importantly, we also show that the effect of spatial location on attention is mediated by emotion, which is in line with the argument that emotional information is prioritized in processing. Auditory system functions as an alarm system and is in charge of detecting possible salient events, and alarming for an attention shift. Further, spatial processing in the auditory dorsal pathway has a function of guiding the visual system to a particular location of interest. Thus, an auditory bias toward the space outside the visual field can be useful, so that visual attention could be quickly shifted in case of emotionally significant information.

The affect heuristic, mortality salience, and risk: domain-specific effects of a natural disaster on risk-benefit perception

We examine how affect and accessible thoughts following a major natural disaster influence everyday risk perception. A survey was conducted in the months following the 2004 south Asian Tsunami in a representative sample of the Swedish population (N = 733). Respondents rated their experienced affect as well as the perceived risk and benefits of various everyday decision domains. Affect influenced risk and benefit perception in a way that could be predicted from both the affect-congruency and affect heuristic literatures (increased risk perception and stronger risk-benefit correlations). However, in some decision domains, self-regulation goals primed by the natural disaster predicted risk and benefit ratings. Together, these results show that affect, accessible thoughts and motivational states influence perceptions of risks and benefits.

The Effect of Interior Aircraft Noise on Pilot Performance

This study examined the effect of the interior sounds of an aircraft cockpit on ratings of affect and expected performance decrement. While exposed to 12 interior aircraft sounds, of which half were modified to correspond to what is experienced with an active noise reduction (ANR) headset, 23 participants rated their affective reactions and how they believed their performance on various tasks would be affected. The results suggest that implementation of ANR-technique has a positive effect on ratings of expected performance. In addition, affective reactions to the noise are related to ratings of expected performance. The implications of these findings for both research and pilot performance are discussed.

Regulation of Experienced and Anticipated Regret for Daily Decisions in Younger and Older Adults in a Swedish One-Week Diary Study

Regret and regret regulation were studied using a weeklong web-based diary method. 108 participants aged 19 to 89 years reported regret for a decision made and a decision to be made. They also reported the extent to which they used strategies to prevent or regulate decision regret. Older adults reported both less experienced and anticipated regret compared to younger adults. The lower level of experienced regret in older adults was mediated by reappraisal of the decision. The lower level of anticipated regret was mediated by delaying the decision, and expecting regret in older adults. It is suggested that the lower level of regret observed in older adults is partly explained by regret prevention and regulation strategies.
