Effets de l’expression écrite d’un événement positif et négatif sur le niveau d’anxiété d’étudiants de différentes disciplines

This study concerns the field of writing and its influence on the emotional state of writers (Pennebaker, 2002). In this field of research, participants are usually requested to express their feelings and emotions following the occurrence of negative events. It is thus important to collect data concerning the influence of positive experiences. By contrast, our study aimed at exploring the impact of expressive writing in two opposite contexts. One context concerns a negative experience (exam's failure) and the other context refers to a positive experience (exam's success). Expressive writing is usually studied in relation to mental (mostly depression) and physical health of the participants. The impact of expressive writing affect on the writers’ anxiety has more rarely been investigated. This is the reason why we have examined the effect of writing on the levels of anxiety of writers. Writing expertise has also been shown to depend on academic disciplines. To fulfill these different goals, undergraduate students (n = 119) belonging to three different university discipliones (arts, sciences and psychology students) responded to the S-Anxiety scale and when then required to write about their feeling concerning the positive or negative topics. The level of anxiety was again measured afterwards. The main question under investigation is to know if emotion regulation (in the sense of Lepore et al., 2002) would vary as a function of the nature of the described event. We hypothesize that variations in anxiety would depend on these events and that impact of emotional regulation would also differ according to the students’ curses. The results show that sciences students are not as verbose (measures in terms of verbal volume) than arts and psychology students. Moreover, emotional content of writing has been analyzed with Emotaix-Tropes (Piolat and Bannour, 2009a). Whatever the course, students produced both positive and negative lexicon for the two topics. However, positive lexicon was proportionally more important in the Success and an inverse result was observed in the Failure situation. The anxiety level was higher following the use of negative valence lexicon and was lower following the use of lexicon of positive valence. The short term beneficial effect of disclosure is thus not observed in case of a negative event. In addition, students with a scientific curse showed more variations in their emotional state.     

A Room with an Overview: the Effects of Schematic Processing,Mood and Exposure Duration on Memory Accuracy

Studies often posit the processing dichotomy of positive vs. negative affect. People in a negative mood tend to process information in a more systematic manner while those in a positive mood tend to adopt a more heuristic, schema-directed processing style. A 3 (mood: negative vs. neutral vs. positive) × 2 (exposure duration: one vs. five minutes) × 2 (schema-consistent vs. schema-inconsistent items) experimental design was employed in a real-life setting and, using the incidental learning paradigm, to test recognition memory for objects in a typical office. Following the affect-as-information approach, we hypothesized that induced positive mood would lead participants to engage in a more schema-directed processing leading to less accurate memory, while induced negative mood will lead to a more analytic and detailed processing, leading to higher memory accuracy and fewer memory errors. Results revealed a significant effect of duration, indicating that participants made more schema-consistent errors when their stay in the office was shorter. The significant interaction of mood and exposure duration suggests that effect of the exposure on memory accuracy applies to people in negative and neutral mood, while people in positive mood tend to maintain schema-directed processing style for longer period of time.     

The influence of mood on the search for supporting versus conflicting information: dissonance reduction as a means of mood regulation?

Focusing on similarities between the mood regulation approach and dissonance theory, this article addresses the interplay between dissonance and mood by examining how individuals search for information after making a decision while under the influence of positive versus negative mood. Study 1 suggested that negative mood increased the preference for consonant over dissonant information after decisions, whereas positive mood led to a more balanced information search. In Study 2, participants in negative mood rated consonant information as more pleasant and dissonant information as more annoying than participants in positive mood. In addition, the results suggested that mood regulation processes took place. In Study 3, the findings from Study 1 were replicated with a paradigm in which higher stakes were involved.     

Les effets de l’ingestion aiguë d’alcool sur le jugement d’expressions faciales émotionnelles spontanées et dynamiques

This study is interested in the link between acute alcohol consumption and the perception of dynamic and spontaneous emotional facial expressions (EFE). The noxious effects of alcohol on EFE recognition are now well demonstrated (Attwood et al., 2009a). Studies showed that alcohol drinking impairs the judgment of facial expressions, especially of negative ones (EFE of anger and disgust notably). However, such effects have been observed for the judgment of artificial material (static/posed/morphed/EFE). Yet, everyday EFE are far from the archetypes used in the lab. Therefore, the present study aims at completing previous observations, this time for the identification of dynamic and spontaneous EFE. Dynamic and spontaneous EFE of amusement, interest, irritation, anxiety, and neutral were judged by 63 normal male drinkers. Buck et al.’s (1972) paradigm was adopted since it is recommended for the study of nonverbal behavior in the process of communication ( [Buck, 1990] , [Wagner, 1990] , [Wagner et al., 1986] and [Zuckerman et al., 1976] ). The emotion to be identified is the one self-reported by the EFE sender. On the pretext of tasting drinks, participants were randomly assigned to one out of six experimental conditions. Two conditions are concerned with the nature of the drink (alcohol or non-alcohol drink). Three other conditions relate to the participant's experimentally manipulated belief regarding the nature of the drink (non-alcohol drink, slight alcohol drink, hard alcohol drink). Results confirm the emotion identification impairment due to alcohol usually noted, thus showing that the effects of alcohol are also observed for the perception of spontaneous and natural facial expressions. Indeed, the comparison of participants who drank alcoholic drinks versus those who did not drink alcohol shows that the formers identify less well emotions than the latter. Moreover, results show that beliefs do not play a role in this deficit since participants’ identification errors are not linked to the belief they hold regarding the nature of the drink (with/without alcohol). Finally, the confusion matrix analysis brings to light the existence of recurrent confusions amongst alcoholized participants, confusions that do not appear amongst sober participants. Thus, results show that, to the exception of EFE of amusement, participants who drank alcohol recurrently assess stimuli as displaying anxiety. To conclude, it comes out that acute alcohol drinking alters the capacity to accurately identify spontaneous emotions expressed by faces, which capacity is essential to the smooth unfolding of human interactions.     

Mood,dissociation and false memories using the Deese‐Roediger‐McDermott procedure

Who is likely to have a false memory? Does being in a certain transient state, such as a negative mood, mean that a person is more like to have a false memory? These important questions are examined using the Deese‐Roediger‐McDermott (DRM) procedure. The amount of false memories was compared with people's score on a dissociation measure and by mood. Unlike past research, which has used different procedures to explore false memories, we found that dissociation was not associated with false memories. We argue that this is because the DRM procedure requires two processes for a false memory (the generation of the critical lure and mistaking its source), while most false memory procedures only require one process (source monitoring error) because the errant information is suggested to the participant. This pattern of results suggests that only errors with the source monitoring process are associated with dissociation. We found that mood was related to false memories, but it was dependent on the specific task demands. If participants were told to recall as many words as they could, then people in a negative mood had more false memories. However, if they were told to recall as many words as they felt like recalling, then there were more false memories for people in a positive mood. This can be explained by the mood‐as‐input hypothesis. Results are discussed in relation to both theories and applications of memory.     

Did I do that? Self–esteem–related differences in reactions to romantic partners’ moods

This study examined the relation between self–esteem and responses to a romantic partner's moods. College students in dating relationships imagined one scenario in which their romantic partners were in a positive mood and one in which their partners were in a negative mood. A probable source of each mood was suggested to half the participants. Participants reported their cognitive, affective, behavioral, and attributional responses to each scenario. When the partner's mood was negative and ambiguous in cause, participants with low self–esteem felt more responsible for the mood, more rejected, and more hostile than did those with high self–esteem. A mediational analysis suggested a dependency regulation explanation of the results, such that low self–esteem people perceived self–directed negativity in their partners’ bad moods and in turn responded with more negativity toward their partners.     

Event centrality of positive and negative autobiographical memories to identity and life story across cultures

The aim of this study was to investigate whether cultural differences exist in event centrality, emotional distress and well-being in a total of 565 adults above age 40 from Mexico, Greenland, China and Denmark. Participants completed questionnaires to determine their level of post-traumatic stress disorder and depression symptoms, and of life satisfaction. They also completed event centrality scales for their most positive and most negative life events. Across cultures, participants rated positive events as more central to their identity and life stories, compared with negative events. Furthermore, participants with higher levels of emotional distress rated negative events as more central to their identity and life story, compared with participants with lower scores. However, a converse pattern was not found for positive events. Finally, participants with higher scores of life satisfaction tended to rate positive events as more central and negative events as less central to their identity and life story, compared with participants with lower scores. It is concluded that across cultures, positive events are considered more central to identity and life story than negative events and that event centrality ratings tend to be affected in similar ways by higher versus lower levels of emotional distress or well-being.     

Fishing for happiness: the effects of generating positive imagery on mood and behaviour

Experimental evidence using picture-word cues has shown that generating mental imagery has a causal impact on emotion, at least for images prompted by negative or benign stimuli. It remains unclear whether this finding extends to overtly positive stimuli and whether generating positive imagery can increase positive affect in people with dysphoria. Dysphoric participants were assigned to one of three conditions, and given instructions to generate mental images in response to picture-word cues which were either positive, negative or mixed (control) in valence. Results showed that the positive picture-word condition increased positive affect more than the control and negative conditions. Participants in the positive condition also demonstrated enhanced performance on a behavioural task compared to the two other conditions. Compared to participants in the negative condition, participants in the positive condition provided more positive responses on a homophone task administered after 24h to assess the durability of effects. These findings suggest that a positive picture-word task used to evoke mental imagery leads to improvements in positive mood, with transfer to later performance. Understanding the mechanisms underlying mood change in dysphoria may hold implications for both theory and treatment development.     

Is manipulation of mood a critical component of cognitive bias modification procedures?

This paper investigates whether changes in mood state are an important component of cognitive bias modification (CBM) procedures. In a novel CBM procedure participants read either positive or negative statements relating to social issues for 5 min. Interpretation bias was measured by means of a scrambled sentence test, which was presented both before and after the CBM procedure. Participants who read the positive statements made more positive resolutions to the scrambled sentences, while participants who read the negative statements made more negative resolutions. Thus, the appropriate positive and negative interpretative biases were induced by the CBM procedure. However, significant mood changes also occurred following CBM. In Experiment 2, a musical mood induction procedure was presented with depressing or elating music. As before, a scrambled sentence test was presented both before and after the musical mood induction. Mood changed in accordance with the valence of the music to the same extent as with CBM. Critically however, performance on the scrambled sentence task did not change for both groups. This demonstrates that a change in mood state is not sufficient for a change in cognitive bias to occur.     

Is the seductive details effect moderated by mood? An eye‐tracking study

According to the seductive details (SD) effect, interesting, but irrelevant information in learning materials reduces learning outcomes. Basic research suggests that subjects in positive mood are more distractible by task‐irrelevant stimuli than subjects in negative mood. Hence, mood could moderate the SD effect. We tested this assumption by comparing eye movements to seductive pictures in participants in positive versus negative mood. As expected, participants in positive mood fixated pictures longer and more frequently than participants in negative mood, which can be interpreted in terms of mood‐based higher distractibility. However, this did not translate to a more pronounced SD effect in the learning test. Unexpectedly, there was no SD effect in either mood condition. We discuss implications of the eye‐tracking data as well as potential reasons for the nonexistent SD effect in our study.     

Effects of mood on self-appraisal of health status

Two experiments investigated the effects of temporary mood on the self-perception of health status. In Experiment 1, participants viewed one of two videotapes designed to induce either positive or negative mood. Under the guise of a second experiment, they were asked to imagine an illness-related scenario and to provide judgments concerning their health status. As predicted, positive-induction participants judged their health more favorably than negative-induction participants. Experiment 2 examined the mediating role of illness-relevant thinking in this mood effect. After seeing one of the two mood-induction tapes, some participants were asked to imagine either an illness-related or illness-unrelated scenario. A third group was given no instructions concerning imagination. As predicted, the relative effect of negative mood on health appraisal was attenuated only among those who imagined a scenario unrelated to health. Furthermore, the pattern of symptom recall data mirrored the self-appraisal findings. The data are consistent with the notion that negative mood can affect subjective appraisals of health by increasing the accessibility of illness-related memories. Implications for diagnostic practice are explored.     

Attentional selection is biased toward mood-congruent stimuli

One can exert significant volitional control over the attentional filter so that stimuli that are consistent with one's explicit goals are more likely to receive attention and become part of one's conscious experience. Here we pair a mood induction procedure with an inattentional blindness task to show that one's current mood has a similar influence on attention. A positive, negative, or neutral mood manipulation was followed by an attentionally demanding multiple-object tracking task. During the tracking task, participants were more likely to notice an unexpected face when its emotional expression was congruent with participants' mood. This was particularly true for the frowning face, which was detected almost exclusively by participants in the sad mood induction condition. This attentional bias toward mood-congruent stimuli provides evidence that one's temporary mood can influence the attentional filter, thereby affecting the information that one extracts from, and how one experiences the world.     

Short-term mood repair through art-making: Positive emotion is more effective than venting

We examined two mechanisms by which creating visual art may serve as a form of short-term mood repair. After viewing a film that induced a negatively valenced mood, participants were given a self-report affect grid that assessed mood valence and arousal. Participants then engaged in one of three tasks: creating a drawing expressing their current mood (venting), creating a drawing depicting something happy (positive emotion), or scanning a sheet for specific symbols (distraction control). Mood valence and arousal were then reassessed. Arousal remained unchanged after the interventions in all conditions. Valence became more positive in all three conditions, but the greatest improvement occurred after the positive emotion intervention. Valence improved no more after venting than after the control task. Results show that in the short-term, attending to and venting one’s negative feelings through art-making is a less effective means of improving mood than is turning away from a negative mood to something more positive. These findings are consistent with research on the beneficial effects of positive emotions and cast doubt on the often assumed view that artists improve their well being by expressing suffering.     

Self-Esteem, Mood, and Intentions to Use Condoms: When Does Low Self-Esteem Lead to Risky Health Behaviors?

The authors assessed the interactive effects of self-esteem and mood on intentions to engage in unprotected sexual intercourse. Prior research has shown that people with low self-esteem tend to evaluate themselves unfavorably when in a negative mood state, whereas people with high self-esteem are less susceptible to changes in self-evaluation following a negative mood induction. The authors hypothesized that people who engage in negative self-evaluations may be more likely to report intentions to engage in unprotected sexual intercourse. Undergraduate females were randomly assigned to a positive or negative mood induction condition. Consistent with their hypotheses, the authors found that among participants who were in a negative mood state, those with low self-esteem were more likely to report intentions to have sexual intercourse without a condom than were those with high self-esteem. In contrast, among participants in a positive mood, there were no differences between those who were low and high in self-esteem.     

How valence affects language processing: Negativity bias and mood congruence in narrative comprehension

The present research examined how positive and negative moods affect readers’ understanding of positive and negative story endings. It demonstrated how negativity bias and mood congruence emerge during narrative comprehension. Participants were induced to experience either a positive or a negative mood and then read stories that could have either a positive or a negative ending. In Experiment 1, participants took longer to integrate negative endings than positive endings, independent of their mood. In Experiment 2, participants judged as more surprising those endings that did not match their mood. The present results illustrate that ending valence has strong influence on moment-by-moment reading, but that readers’ moods influence expectations for story outcomes once readers reflect on a complete representation of the story.     

Effects of mood states on information processing strategies: Two studies of automatic and controlled processing using misattribution paradigms

To test the hypothesis that a positive mood facilitates automatic processing and a negative mood facilitates controlled processing, two experiments were conducted. In Experiment 1, after positive or negative mood was induced, participants rated the attractiveness of products while listening to a music tape that they were told would have the effect of inducing a positive, negative, or neutral mood. As predicted, augmentation effects were clearer in the negative mood condition than in the positive mood condition. In Experiment 2, participants were first presented with lists of names of non-famous Japanese companies either once or four times. One or two days later, they were presented with these names again, together with new names, and were asked to judge whether those names were famous or-non-famous. As predicted, subjects in a positive mood showed more false fame judgments than those in a negative mood because those in a positive mood did not control their feeling of familiarity correctly. These results indicated that those in positive moods are more likely to engage in automatic processing.     

Interactive effects of personality and mood on emotion-congruent memory and judgment

Prior research on emotion congruency has tended to focus on either the effects of mood states or of personality traits on cognition. The aim of the present research was to explore when and how personality traits and mood states interact to influence emotion-congruent memory and judgment. In Study 1, participants filled out measures of personality and natural mood and then completed a series of memory and judgment tasks. The same procedure was used in Study 2, except a positive or negative mood state was induced prior to completion of the cognitive tasks. Extraversion and positive affectivity were related to retrieval of positive memories and the tendency to make positive judgments. Neuroticism and negative affectivity were related to retrieval of negative memories and the tendency to make negative judgments. In addition, several significant personality by mood interaction effects on memory and judgment were obtained in Study 2, which suggests that personality and mood effects on cognition are not independent of one another. Discussion focuses on integrating mood-congruency theories with personality theories and specifying the conditions under which mood by trait interaction effects effects emerge.
