The influence of mood on visual perception of neutral material

In the study we investigated how current mood affects spontaneous perceptual processes of neutral stimuli of low‑arousal, unrelated to any specific task. Two separate but similar procedures were carried out: one using functional magnetic resonance imaging (fMRI), the other using electroencephalography based source localization. In both experiments, sessions of passive viewing of neutral pictures were preceded by either a negative or positive mood induction. In response to neutral stimuli, we observed higher activation of visual areas after positive mood induction and lower activations in medial prefrontal and right frontotemporal regions after negative mood induction. We conclude that in relatively safe laboratory conditions, after being exposed to negative emotional content, automatic processes of affective control are recruited by the prefrontal cortex. This results in attenuation of processing of incoming stimuli, as the stimuli do not carry salient information with respect to bottom‑up or top‑down processes. The observed effects may therefore represent an implicit mechanism of perceptual modulation

Your Morals Are Your Moods

We test the effect of players' moods on their behavior in a gift-exchange game. In the first stage of the game, player 1 chooses a transfer to player 2. In the second stage, player 2 chooses an effort level. Higher effort is more costly for player 2, but it increases player 1's payoff. We say that player 2 reciprocates if effort is increasing in the transfer received. Player 2 is generous if an effort is incurred even when no transfer is received. Subjects play this game in two different moods. To induce a `bad mood', subjects in the role of player 2 watched a sad movie before playing the game; to induce a `good mood', they watched a funny movie. Mood induction was effective: subjects who saw the funny movie reported a significantly better mood than those who saw the sad movie. These two moods lead to significant differences in player 2's behavior. We find that a bad mood implies more reciprocity while a good mood implies more generosity. Since high transfers are relatively more common, player 1 makes more money when second movers are in a bad mood.

Nursing students' anxiety and clinical performance

This study examined how mood states affect nursing students' performance on a treatment procedure consisting of a novel combination of familiar clinical steps. Thirty third-year and fourth-year nursing students were first taught the procedure and then given both an anxious-mood and a calm-mood induction in a randomly assigned counterbalanced order. Anxiety was induced by showing a video of interviews with frontline nurses and doctors during the severe acute respiratory syndrome epidemic in Hong Kong, China; calmness was induced by a video of a nursing student's pleasant orientation to a clinical placement site. Nursing students were significantly less proficient in performing the newly acquired procedure after an anxious-mood induction (focused on occupational risks) than after a calm-mood induction. Therefore, managing clinical training site anxiety among nursing students may help to optimize learning and clinical performance. © SLACK Incorporated.postprin

Positive and neutral mood inductions: ties to creativity

Positive mood may broaden cognition, allowing for an increase in creativity. This study tested whether creativity could be increased when positive mood and creativity were induced through verbal instructions that direct ed participants to revisit memories that depicted positive mood and/or creative moments. This experiment had a 2(mood induction positive/neutral) X 2(creativity induction yes/no) design, and 112 participants in four condi tions: 22 in the first, 33 in the second, 25 in the third, and 32 in the fourth. Mood and creativity inductions were autobiographical, as this method is the most effective technique for inducing mood. Scales used were the Torrance Tests of Creative Thinking and the Brief Mood Introspection Scale. Findings indicated that creativity can be increased when positive mood and creative thinking are induced in the same experimental condition versus inducing creativity or mood separately or not at all. This study has implications for understanding factors that produce creative though

Negative mood state impairs false memory priming when problem-solving

The aim of this study was to investigate the effect of emotional mood states on the ability to create effective primes using the recently developed false memory priming paradigm. A negative or positive mood state was induced before Deese/Roediger-McDermott (DRM) list presentation. A further control group experienced no mood induction. Participants were then presented with Compound Remote Associate Task (CRAT) problems, half of which had been primed by the previous DRM lists whose critical lure was the solution to the CRAT problem. The results of this study showed that induction of a negative mood state not only impaired recall of critical lures but also diminished their effectiveness as primes for solving CRAT problems. In contrast, for both positive mood and control conditions, the false memory priming advantage was evident, with a higher proportion of primed problems solved in comparison to those not primed. Findings are discussed in relation to the role of affect on semantic activation and the adaptive consequences of false memories

The responsiveness of negative cognitive content to an induced negative mood state in those with and without a previous history of depression in a student sample

This study investigates the responsiveness of cognitions to an induced negative mood state in those with and without a previous history of depression in a non-clinical student sample (n = 101). The Automatic Thought Questionnaire (ATQ-30) was used to observe the negative cognitive content. The negative mood state was induced in small groups utilising the Velten Negative Mood Induction Procedure (VNMIP). Self-reported mood was measured using the University of Wales Institute of Science and Technology (UWIST) Mood Adjective Checklist (UMACL) before and after VNMIP. The effects of previous history of depression (without history or with previous history of depression) and self-reported mood (pre or post negative mood induction) on cognitive content was shown in a 2 x 2 ANOVA with time (pre-test vs. post-test) as a within subjects factor and history of depression (with a history of depression vs. without a history of depression) as a between subjects factor. The results indicate no significant interaction between time and group in their effects on negative cognitive content. Also, there was no significant main effect for time on negative cognitive content. However, there was a significant main effect for previous history of depression on negative cognitive content. Findings are discussed on the basis of the literature and possible applications for practice

Emotion word processing: does mood make a difference?

Visual emotion word processing has been in the focus of recent psycholinguistic research. In general, emotion words provoke differential responses in comparison to neutral words. However, words are typically processed within a context rather than in isolation. For instance, how does one's inner emotional state influence the comprehension of emotion words? To address this question, the current study examined lexical decision responses to emotionally positive, negative, and neutral words as a function of induced mood as well as their word frequency. Mood was manipulated by exposing participants to different types of music. Participants were randomly assigned to one of three conditions—no music, positive music, and negative music. Participants' moods were assessed during the experiment to confirm the mood induction manipulation. Reaction time results confirmed prior demonstrations of an interaction between a word's emotionality and its frequency. Results also showed a significant interaction between participant mood and word emotionality. However, the pattern of results was not consistent with mood-congruency effects. Although positive and negative mood facilitated responses overall in comparison to the control group, neither positive nor negative mood appeared to additionally facilitate responses to mood-congruent words. Instead, the pattern of findings seemed to be the consequence of attentional effects arising from induced mood. Positive mood broadens attention to a global level, eliminating the category distinction of positive-negative valence but leaving the high-low arousal dimension intact. In contrast, negative mood narrows attention to a local level, enhancing within-category distinctions, in particular, for negative words, resulting in less effective facilitation

Phenomenological characteristics of autobiographical memories: responsiveness to an induced negative mood state in those with and without a previous history of depression.

This document is the Accepted Manuscript version of a published work that appeared in final form in Advances in Cognitive Psychology. To access the final edited and published work see http://dx.doi.org/10.5709/acp-0190-8.In this study we investigated the relative accessibility of phenomenological characteristics in autobiographical memories of 104 students with and without a previous history of a depression. Participants recalled personal events that were elicited with cue words and then asked to rate these personal events for a number of phenomenological characteristics. The characteristics were typicality, rumination, valence, importance of others, expectancy, desirability, and personal importance. The effects of previous history of depression (without history or with previous history of depression) and self-reported mood (pre- and post-negative mood induction) on autobiographical recall was examined by employing a mixed factor design. Self-reported mood was measured as a manipulation check, before and after Mood Induction Procedure. Typicality, rumination and personal importance showed significant interaction effects in those with a history of depression. Ordinal regression supported the finding that those with a history of depression had a higher chance of typicality and personal importance than those without a history of depression. The results indicate that recall of autobiographical characteristics is in part dependent on induced negative mood state and on previous history of depression. The findings may prompt future research into targeted interventions that reduce individual tendencies for heightened cognitive reactivity in negative mood states for those with a history of depression
