Induced boredom suppresses the recall of positively valenced information: A preliminary study

The mood-congruence memory (MCM) effect in the case of depressed mood is typically evidenced by enhanced recall of negatively valenced information and/or a corresponding reduction in the recall of positive information. However, the impact of the related affect of boredom on memory has been overlooked. A sample of undergraduate and graduate students (n = 28) were asked to either read an interesting story (Low Boredom condition) or complete a tedious vowel-counting task (High Boredom condition) after studying a list of neutral, negative, and positive words. Following the experimental manipulation, the participants were asked to recall as many words from the list as they could remember. The participants in the low boredom (LB) group reported (i.e., recalled words + misremembered words) significantly more positive words than participants in the high boredom (HB) condition. However, no differences were found between groups in terms of the total number words reported, total number of positive, neutral or negative words recalled, or the overall accuracy of recall. Boredom appears to inhibit the reporting and recall of positively valenced information, but seems to have less influence on the recall and reporting of emotionally negative information than what is typically reported in studies with depressed mood. This finding is consistent with a conception of boredom as an affect state that is more closely tied to the perceived depletion of potential positive reinforcement (e.g., novelty, enjoyment, meaningfulness) than the depletion of negative reinforcement (e.g., escape from suffering, loss, failure). Larger implications of the findings are discussed.

Proposal of Episodic Memory Retrieval Method on Mood Congruence Effects

Developments in robotics have advanced the development of robots that can communicate with humans. However, a few robots are only capable of stereotypic responses, and this leads to barriers in smooth communication between humans and robots. In this study, in order to represent mood congruence effects, an episodic memory retrieval method is proposed based on a robot’s emotional values that represent its internal state. In the study, impression evaluation experiments were conducted to prove the effectiveness of the proposed method.

The Effect of Mood on Performance in a Nonnormal Situation

The effect of mood on performance in everyday situations is widely studied and the results commonly reveal a mood-congruence relationship. However, little is known about the effect of mood on performance in nonnormal situations such as those experienced during an unscheduled event. This study investigated whether induced mood (positive or negative) influenced performance during an unscheduled aircraft evacuation. Forty-five participants (15 female), with an average age of 21.90 (SD = 3.96) years, were randomly exposed to either positive or negative mood facilitation. Following this, all participants watched the same preflight safety video, and then had to conduct an unscheduled evacuation following a simulated water ditching. Participants exposed to a positive mood manipulator were found to commit fewer errors during the evacuation exercise and completed the evacuation in less than half of the time taken by participants who were exposed to a negative mood manipulator. In safety-critical environments such as aviation, these results highlight the advantages of creating an atmosphere or environment that induces positive moods.

The Effects of Gender Differences in Patients with Depression on Their Emotional Working Memory and Emotional Experience

A large amount of research has been conducted on the effects of sex hormones on gender differences in patients with depression, yet research on cognitive differences between male and female patients with depression is insufficient. This study uses emotion pictures to investigate the differences of the emotional working memory ability and emotional experience in male and female patients with depression. Despite identifying that the working memory of patients with depression is impaired, our study found no significant gender differences in emotional working memory. Moreover, the research results revealed that memory effects of mood congruence are produced in both men and women, which may explain why the depression state can be maintained. Furthermore, female patients have more emotional experiences than male patients, which is particularly significant in terms of negative emotional experiences. This result provides cognitive evidence to explain why women suffer from longer terms of depression, are more susceptible to relapse, and can more easily suffer from major depressive disorder in the future.

Mood congruence effect in autobiographical recall: Is mood a mediator?

In the present study we test the hypothesis that the effect of mood congruence in autobiographical recall is underlain by mood. Thirty-eight female participants were subjected to positive, negative and neutral mood inductions, and then asked to recall three personal memories. Participants? mood was assessed using self-report questionnaires and by electromyograph (EMG) measurements of corrugator supercilii and zygomaticus major muscle activity. We replicated the congruence effect between the mood inductions and the valence of the participants? recalled memories. Furthermore, this effect was mediated by mood, as measured by EMG and self-report questionnaires. The results suggest that mood influences the mood congruence effect in a way that cannot be explained by semantic priming alone.
