Emotional eating following a laboratory mood induction: The interaction between parental feeding practices and child temperament

Children who emotionally eat (EE) tend to consume palatable foods that are high in sugar and fat. How EE develops remains unclear, but children’s temperament and parental feeding practices may interact to shape child EE. To date, no research has explored these interaction effects on EE experimentally. Furthermore, most research has explored EE in response to generic ‘negative’ mood rather than specific negative emotions, such as boredom, which has never been explored in this context. This study aimed to explore interactions between induced mood condition (sadness, boredom, control), parent-reported non-responsive feeding practices and parent-reported child temperament (negative affect, surgency, effortful control) in predicting kilocalories consumed by children aged 4–5-years in a laboratory setting. Using three-way ANOVA, the interactions between mood state, parental feeding practice and child temperament were assessed. Results indicated that children who experienced boredom consumed significantly more total kilocalories than children in the control condition. Additionally, children with high negative affect who also had parents who reported high use of food for emotion regulation consumed significantly more kilocalories from sweet food when experiencing boredom compared to control condition, and children with high negative affect who also had parents who reported low use of food as a reward consumed significantly more kilocalories from sweet food when experiencing boredom compared to control condition. These findings suggest that feelings of boredom differentially predict children’s snack food intake, and that child negative affect and non-responsive feeding practices play an important role in the expression of this relationship.

A - 67 Does Cognitive Set-Shifting in Multilinguals Serve as a Protective Factor against Depressive Rumination?

The purpose of this study is to assess whether multilinguals' advantage in cognitive flexibility serves as a protective factor against ruminative tendencies common in depressed mood. We compared monolinguals and multilinguals in a backward inhibition task during negative and neutral moods. It was hypothesized that monolinguals compared with multilinguals would perform worse on inhibition trials compared to control when induced into a negative mood. 96 undergraduates from Queens College, a population with high linguistic diversity, were recruited from Psychology 101 courses. Participants were monolingual (n = 47) or multilingual (2+ languages; n = 49). Participants responded to questions about their language and social background before undergoing mood induction to either neutral or negative (sad) affective states. They then completed a computerized cognitive set-shifting task measuring reaction time (RT) and accuracy. A two-way ANOVA was conducted examining the effect of mood condition and mono/multilingualism status on RT and accuracy on the set-switching task for backward inhibition trials. There was a statistically significant interaction between the effects of mood condition and mono/multilingualism on RT, F(1, 92) =6.062, p = 0.002, such that multilinguals had a higher RT compared to monolinguals when induced into a negative mood. The main effects of mono/multilingualism and mood condition were not statistically significant. Difference in accuracy between groups was not statistically significant. Contrary to our hypothesis, bilinguals took longer to respond than monolinguals in a sad mood, specifically for lag inhibition trials. Additional research is needed to determine how sociocultural factors may explain multilinguals' slowed response in a negative mood.

Modeling the value-based decision to consume alcohol in response to emotional experiences.

Evidence for negative reinforcement of alcohol use is mixed; one possible explanation for this is that people make value-based decisions whether to regulate their emotions via alcohol or an alternative, and only drink-to-cope when alcohol's reinforcing value is larger than that of available alternatives. If this is the case, immediately following a negative emotional event, the value for alcohol should increase primarily in heavy drinkers, whereas in light drinkers, alternative ways of coping should be valued. We conducted a preregistered online experiment (N = 200) with a mixed design (between: heavy vs. light drinker; within: negative/neutral/positive mood induction). In each of three experimental sessions, participants first provided value ratings for a set of alcohol and food stimuli. Second, they were subjected to a mood induction. Third, they made forced choices between either two alcohol or food stimuli. We then applied a drift-diffusion model to these data and tested whether alcohol- and food-related decision-making parameters are differentially affected following the mood inductions in heavy and light drinkers. In preregistered analyses, we found that heavy drinkers did not value alcohol more but valued food less after the negative mood induction. Exploratory analyses uncovered that both heavy- and light-drinking participants valued alcohol more following the negative mood induction if they reported high alcohol craving at the start of the session. Collectively, these results provide some evidence for the idea that drinking-to-cope might be a value-based decision-making process. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Mood induction through imitation of full-body movements with different affective intentions.

Theories of human emotion, including some emotion embodiment theories, suggest that our moods and affective states are reflected in the movements of our bodies. We used the reverse process for mood regulation; modulate body movements to regulate mood. Dancing is a type of full-body movement characterized by affective expressivity and, hence, offers the possibility to express different affective states through the same movement sequences. We tested whether the repeated imitation of a dancer performing two simple full-body dance movement sequences with different affective expressivity (happy or sad) could change mood states. Computer-based systems, using avatars as dance models to imitate, offer a series of advantages such as independence from physical contact and location. Therefore, we compared mood induction effects in two conditions: participants were asked to imitate dance movements from one of the two avatars showing: (a) videos of a human dancer model or (b) videos of a robot dancer model. The mood induction was successful for both happy and sad imitations, regardless of condition (human vs. robot avatar dance model). Moreover, the magnitude of happy mood induction and how much participants liked the task predicted work-related motivation after the mood induction. We conclude that mood regulation through dance movements is possible and beneficial in the work context.

The influence of induced dysphoria on autobiographical memory specificity and social problem solving: Examining the role of executive function

Negative mood induction leads to reductions in autobiographical memory specificity (AMS) and social problem-solving (SPS). The aim was to establish if executive function contributes to changes in AMS and SPS following negative mood induction. Forty-four participants (study 1) completed the autobiographical memory test and measures of executive function (letter & category fluency) before and after a positive or negative mood induction (MI). Forty participants (study 2) completed the means-end problem solving task (MEPS) and (letter & category) fluency tasks before and after a positive or negative MI. In study 1, participants exhibited impaired AMS and fluency performance following a sad MI. Decrease in memory specificity pre-to post-MI was related to reductions in happy mood and letter fluency. In study 2, participants exhibited poorer performance on the MEPS and fluency tasks following a sad MI. Decreases in the number of relevant solutions generated on the MEPS pre-to post-MI was linked to increases in sad mood and decreases in letter fluency. In both studies, the influence of mood became non-significant once the effect of executive function was accounted for, which suggests that changes in AMS and SPS in response to induced mood were related to concomitant changes in executive function.

Melodic Melodies: Is That All There is to Music?

Music has great benefits; music can improve mood which in turn enhances cognitive performance in the brain. The objective of this literature review is to see how musical induction, the process of using mood induction through music, can change affect. Affect is the emotional reactive response to stimuli. With time, affect can influence mood, becoming an emotional state that stays stagnant for a prolonged period of time. Positive affect and mood benefit cognitive performance in 4 domains: attention and processing speed, working memory, declarative memory, and executive function. Results from scientific journals, blogs, and journal articles were reviewed to [paraphrased + shortened research question]. Studies suggest that musical induction can induce positive affect, enhancing cognitive performance in memory, processing speed, and attention. Since music is prevalent in daily lives, understanding how brain functions benefit positively from musical induction is extremely important; these tools and knowledge will be beneficial in solving mental health issues and other crises.

Making Versus Viewing Art: Effects on Affect, Enjoyment, and Flow

In two studies, we compared whether making and viewing art improved affect and whether the affective benefits were due to participants’ experience of enjoyment and flow. In Study 1, participants engaged in an art-making and art-viewing activity separated by one week. In Study 2, participants were randomly assigned to an art-making or art-viewing activity. In both studies, we induced a negative mood in participants by having them watch a sad film clip. We measured positive and negative affects before and after the mood induction and after the activity. In Study 2, participants rated levels of enjoyment and flow experienced during the activity. Both making and viewing art reduced negative affect equally. However, making art improved positive affect more than viewing art, and making art was associated with greater enjoyment than viewing art. Actively making art is a potentially more powerful way to improve affect than passively viewing art.

Inhibitory control towards angry stimuli in patients with binge eating disorder: a pilot study

BackgroundEmotion regulation theories and the negative urgency concept assume that negative mood increases binge eating. Negative emotions are considered as a trigger for binge eating, while binge eating itself is regarded as an impulsive behavior and should thus be increased within the negative urgency concept. Anger might be a specific negative emotion triggering binge eating in patients with binge eating disorder (BED). We investigated how inhibitory control as one main factor of impulsivity is influenced by anger stimuli in patients with BED and two control groups.MethodsWe compared patients with BED (N = 20) with normal-weight healthy control participants (NW-CG, N = 20) and BMI-matched overweight and obese control participants (BMI-CG, N = 18). We used the emotional Stop Signal task (eSST) to investigate inhibitory control, where we presented angry facial expressions in comparison with neutral facial expressions as emotional stimuli.ResultsAll participants showed decreased inhibitory control in the angry versus neutral condition, i.e., a faster Stop Signal Reaction Time and a lower percentage of correct reactions. However, no significant group differences emerged in terms of performance. Performance in the eSST did not correlate with negative urgency, disorder- or emotion-related characteristics.ConclusionsThe current pilot study does not deliver evidence for decreased inhibitory control towards angry stimuli in patients with BED, as we detected a general and not disorder-related effect in all participants that might represent the conjunction of inhibitory control and anger. A direct mood induction technique might have led to different results. Further research in healthy and clinical groups is needed.

Interpersonal stress and proinflammatory activity in emerging adults with a history of suicide risk: A pilot study

Interpersonal stress during adolescence and young adulthood can threaten healthy developmental trajectories. A “primed” proinflammatory response to acute stress may serve as an underlying process that results in negative outcomes for youth. The present pilot study examined the relation between interpersonal stress and two proinflammatory cytokines in a sample of 42 university-recruited emerging adults with recent suicidal thoughts and behaviors. Participants completed self-report measures of mood, suicidal thoughts and behaviors, recent peer-related stressors, and interpersonal sensitivity. They also participated in an acute laboratory social stress task and provided three saliva samples to measure their proinflammatory responses (IL-6 and TNF-α) to the stressor. Participants reported significant increases in sadness and exclusion, and significant decreases in inclusion, following task participation. Importantly, no participants reported an increase in or onset of suicidal thoughts. No significant associations between interpersonal stress and proinflammatory cytokines were found. Changes in affect during the task coupled with lack of increased suicidal thoughts indicate it is acceptable to use this exclusion and rejection paradigm with this population, with proper debriefing and positive mood induction procedures. Given all other nonsignificant associations, future research considerations are discussed, including impact of COVID-19 on task potency and incorporation of multiple stress response systems.

Longitudinal and experimental investigations of implicit happiness and explicit fear of happiness

ABSTRACT Some individuals devalue positivity previously associated with negativity (Winer & Salem, 2016). Positive emotions (e.g. happiness) may be seen as threatening and result in active avoidance of future situations involving positivity. Although some self-report measures can capture emotions of happiness-averse individuals, they are not always capable of capturing automatic processing. Thus, we examined the association between implicitly-assessed happiness and explicit (i.e. self-reported) fear of happiness in three studies. In Study 1, participants completed the Fear of Happiness Scale (FHS) and an implicit measure of emotions at four-time points over approximately one year. The implicit measure required participants to choose which emotion (i.e. anger, fear, happiness, sadness, or none) best corresponded to 20 individual Chinese characters. In Studies 2 and 3, we utilized an experimental design, implementing a mood induction to emphasise the relationship between explicit fear of happiness and implicitly-assessed happiness. Participants completed the FHS and chose which emotion they believed the artist tried to convey in 20 abstract images. Results indicated that greater self-reported fear of happiness was related to reduced implicit happiness. Findings from these studies provide compound evidence that individuals who hold negative views of positivity may process implicit happiness in a devaluative manner.

Effect of Taste-Induced Mood on ERP and Emotional Assessment of Images.

Tastes affect the body and our emotions. We used tasteless, sweet, and bitter stimuli to induce participants' moods, and we examined the effect of mood on an emotional evaluation of pleasant, neutral, and unpleasant images using event-related potentials, N2, N400, and late positive potential (LPP), which reflect emotional evaluation in the brain. The results indicated that mood valence was most positive for sweetness and most negative for bitterness. Moreover, there was no significant mood effect on subjective valence ratings of emotional images. Furthermore, the N2 amplitude, which is related to the early semantic processing of preceding stimuli, was unaffected by the taste induced mood. In contrast, we found that the N400 amplitude, which is related to the mismatch of emotional valence between stimuli, increased significantly for unpleasant images when participants were in a positive rather than negative mood state. Also, the LPP amplitude, which is related to the emotional valence of images, showed only the main effect of the images' emotional valence. The N2's results suggest that the early semantic processing of taste stimuli might have had a negligible impact on emotional evaluation because taste stimuli minimize semantic processing that accompanies mood induction. In contrast, the N400 reflected the effects of the induced mood, and the LPP reflected the impact of the valence of emotional images. The use of taste stimuli to induce mood revealed different brain processing of taste-induced mood effects on emotional evaluation, including N2's involvement in semantic processing, N400's involvement in matching emotions between mood and stimuli, and LPP's involvement in subjective evaluations of stimuli.

Amplified gut feelings under inflammation and depressed mood: A randomized fMRI trial on interoceptive pain in healthy volunteers

BackgroundInflammation and depressed mood constitute clinically relevant vulnerability factors for enhanced interoceptive sensitivity and chronic visceral pain, but their putative interaction remains untested in human mechanistic studies. We tested interaction effects of acute systemic inflammation and sad mood on the expectation and experience of visceral pain by combining experimental endotoxemia with a mood induction paradigm. MethodsThe double-blind, placebo-controlled, balanced crossover fMRI-trial in N = 39 healthy male and female volunteers involved 2 study days with either intravenous administration of low-dose lipopolysaccharide (LPS, 0.4 ng/kg body weight; inflammation condition) or saline (placebo condition). On each study, day two scanning sessions were conducted in an experimentally induced negative (i.e., sad) and in a neutral mood state, accomplished in balanced order. As a model of visceral pain, rectal distensions were implemented, which were initially calibrated to be moderately painful. In all sessions, an identical series of visceral pain stimuli was accomplished, signaled by predictive visual conditioning cues to assess pain anticipation. We assessed neural activation during the expectation and experience of visceral pain, along with unpleasantness ratings in a condition combining an inflammatory state with sad mood and in control conditions. All statistical analyses were accomplished using sex as covariate. ResultsLPS administration led to an acute systemic inflammatory response (inflammation X time interaction effects for TNF-α, IL-6, and sickness symptoms, all p <.001). The mood paradigm effectively induced distinct mood states (mood X time interaction, p <.001), with greater sadness in the negative mood conditions (both p <.001) but no difference between LPS and saline conditions. Significant main and interaction effects of inflammation and negative mood were observed for pain unpleasantness (all p <.05). During cued pain anticipation, a significant inflammation X mood interaction emerged for activation of the bilateral caudate nucleus and right hippocampus (all pFWE < 0.05). Main effects of both inflammation and mood were observed in multiple regions, including insula, midcingulate cortex, prefrontal gyri, and hippocampus for inflammation, and midcingulate, caudate, and thalamus for mood (all pFWE < 0.05). ConclusionsResults support an interplay of inflammation and sad mood on striatal and hippocampal circuitry engaged during visceral pain anticipation as well as on pain experience. This may reflect a nocebo mechanism, which may contribute to altered perception and interpretation of bodily signals. At the interface of affective neuroscience and the gut-brain axis, concurrent inflammation and negative mood may be vulnerability factors for chronic visceral pain.

A redesigned mood induction procedure: The emotional rollercoaster of life under experimental control

The aim of this study was to develop a new mood induction procedure in which a positively and a negatively loaded images presented sequentially (or vice versa) alter participants’ mood state. A second objective was to investigate whether baseline results can be replicated at 6 months and whether these induced mood changes depend on sex, age, and image quality (colour and recognition). 82 participants underwent a mood induction procedure at baseline and 6 months. After a measurement in which current happiness, sadness and anger was assessed, they were exposed to two subsequent images of opposite emotional loading. After each image, they were asked to report their mood. Multi-level analyses showed significant effects of both the first image and the second image on participants’ mood. Replication at 6 months was mostly confirmed. Interactions with sex and age were demonstrated partially. No significant colour and recognition effects were found. Unexpectedly, significant order effects of emotional loading were found for all three mood items. This redesigned mood induction procedure resulted in congruent effects on subjective mood. The need for replication of these findings, as well as the extension of the paradigm to clinical populations, is encouraged.

The impact of affective states and traits on perceptual stability during binocular rivalry

Affective states and traits have been associated with different measures of perceptual stability during binocular rivalry. Diverging approaches to measuring perceptual stability as well as to examination of the role of affective variables have contributed to an inconclusive pattern of findings. Here, we studied the influence of affective traits, such as depressiveness and trait anxiety, and states, which were manipulated with a musical mood induction paradigm, on different measures of perceptual stability (dominance ratios and phase durations) during binocular rivalry. Fifty healthy participants reported alternations in two conditions: a biased perception condition with an unequal probability of perceiving stimuli, using an upright versus a tilted face with a neutral expression, and a control condition with equal chances of perceiving stimuli, using Gabors of different orientations. Baseline positive state affect significantly predicted longer phase durations whereas affective traits did not yield any such effect. Furthermore, in an exploratory analysis, induced negative affect attenuated stimulus related bias in predominance ratios. Overall, we found a strong correlation between both measures of perceptual stability (phase durations and dominance ratios). Our findings thus question the distinction between different measures of perceptual stability during binocular rivalry and highlight the role of affective states in its formation.

Tell me how you feel, I will tell you what you look at: Impact of mood and craving on alcohol attentional bias in binge drinking.

Alcohol-related attentional bias (AB) is thought to play a key role in the emergence and maintenance of excessive alcohol use. Recent models suggest that AB, classically considered as a permanent feature in alcohol use disorders, is rather modulated by temporary motivational states. We explored the influence of current mood and craving on AB in binge drinking, through a mood induction procedure combined with eye-tracking measures of AB. In Experiment 1, we measured AB (visual probe task with eye-tracking measures) among binge drinkers (n = 48) and light drinkers (n = 32) following positive, negative and neutral mood inductions. Participants reported subjective craving and mood before/after induction. In Experiment 2, we measured AB among the same binge drinkers compared with 29 moderate drinkers following alcohol-related negative, non-alcohol-related negative and neutral mood inductions. In Experiment 1, induced negative mood and group positively predicted subjective craving, which was positively associated with AB. We found no effect of induced positive mood nor a direct mood-AB association. In Experiment 2, the relationships AB presented with both induced negative mood and group were again mediated by craving. Inducing alcohol-related negative mood did not modify the mood-craving association. Alcohol-related AB is not a stable binge drinking characteristic but rather varies according to transient motivational (i.e., craving) and emotional (i.e., negative mood) states. This study provides important insights to better understand AB in subclinical populations and emphasizes the importance of considering motivational and affective states as intercorrelated, to offer multiple ways to reduce excessive alcohol use.

Perception of emotion in the facial expressions and body language of athletes

Facial expressions are commonly believed to reliably convey emotional information, but some research suggests that people are better at perceiving emotions through body language. We hypothesized that individuals' emotional perception would improve when body imagery was presented, relative to viewing the face alone. Following musical mood induction, participants were shown images of winning and losing tennis players that were cropped to show either (a) only the face, (b) only the body, or (c) both the face and the body, before rating each player's perceived level of arousal and emotional experience. Results showed there was a reciprocal emotional rating effect for face imagery, with participants mistakenly rating losing faces as experiencing more positive emotion than winning faces did; when body imagery was shown along with the face, participants' emotional perception was more accurate. Significant gender differences were observed in ratings of female versus male players. Our study indicates that without further context, emotional perception is unreliable from the face alone. Theoretical and practical implications are discussed.
