    Chocolate is a popular food and its consumption has long been associated with enjoyment and pleasure. The effect of chocolate on mood too has long been recognised. Chocolate is thought to have interactions with neurotransmitters which contribute to mood modulation and appetite regulation. However, the evidence in chocolate and mood studies remains highly controversial. As more is known about the influence of chocolate on mood, the reasons for these effects appear increasingly complex and inter-related.

    Emotions are ambiguous. Many techniques have been employed to perform emotion prediction and to understand emotional elicitations. Brain signals measured using electroencephalogram (EEG) are also used in studies about emotions. Using KDE as feature extraction technique and MLP for performing supervised learning on the brain signals. It has shown that all channels in EEG can capture emotional experience. In addition it was also indicated that emotions are dynamic as represented by the level of valence and the intensity of arousal. Such findings are useful in biomedical studies, especially in dealing with emotional disorders which can results in using a two-channel EEG device for neurofeedback applications.

    Ample research has shown that light influences our emotions, cognition, and sleep quality. However, little work has examined whether different light exposure-related behaviors, such as daytime exposure to electric light and nighttime usage of gadgets, especially before sleep, influence sleep quality and cognition. Three-hundred-and-one Malaysian adults (MeanAge±SD = 28 ± 9) completed the Light Exposure Behavior Assessment tool that measured five light exposure behaviors. They also completed the Morningness-Eveningness Questionnaire, Positive and Negative Affect Schedule, Pittsburgh Sleep Quality Index, and single items assessing trouble in memory and concentration. A partial least square structural equation model, showing 72.72% predictive power, revealed that less use of wearable blue filters outdoors during the day and more within one hour before sleep predicted early peak time (direct effect = -0.25). Increased time spent outdoors predicted a positive affect (direct effect = 0.33) and a circadian phase advancement (direct effect: rising time = 0.14, peak time = 0.20, retiring time = 0.17). Increased use of mobile phone before sleep predicted a circadian phase delay (direct effect: retiring time = -0.25; rising time = -0.23; peak time = -0.22; morning affect = -0.12), reduced sleep quality (direct effect = 0.13), and increased trouble in memory and concentration (total effect = 0.20 and 0.23, respectively). Increased use of tunable, LED, or dawn-simulating electric light in the morning and daytime predicted a circadian phase advancement (direct effect: peak time = 0.15, morning affect = 0.14, retiring time = 0.15) and good sleep quality (direct effect = -0.16). The results provide valuable insights into developing a healthy light diet to promote health and wellness.

    BACKGROUND: Artificial intelligence chatbot research has focused on technical advances in natural language processing and validating the effectiveness of human-machine conversations in specific settings. However, real-world chat data remain proprietary and unexplored despite their growing popularity, and new analyses of chatbot uses and their effects on mitigating negative moods are urgently needed.

    OBJECTIVE: In this study, we investigated whether and how artificial intelligence chatbots facilitate the expression of user emotions, specifically sadness and depression. We also examined cultural differences in the expression of depressive moods among users in Western and Eastern countries.

    METHODS: This study used SimSimi, a global open-domain social chatbot, to analyze 152,783 conversation utterances containing the terms "depress" and "sad" in 3 Western countries (Canada, the United Kingdom, and the United States) and 5 Eastern countries (Indonesia, India, Malaysia, the Philippines, and Thailand). Study 1 reports new findings on the cultural differences in how people talk about depression and sadness to chatbots based on Linguistic Inquiry and Word Count and n-gram analyses. In study 2, we classified chat conversations into predefined topics using semisupervised classification techniques to better understand the types of depressive moods prevalent in chats. We then identified the distinguishing features of chat-based depressive discourse data and the disparity between Eastern and Western users.

    RESULTS: Our data revealed intriguing cultural differences. Chatbot users in Eastern countries indicated stronger emotions about depression than users in Western countries (positive: P

    Centella asiatica (L.) Urb. has been used as an herbal brain tonic for mental disorders and enhancing memory, but no review of the overall evidence of C. asiatica and cognitive function has been conducted. This study aims to determine the effects of C. asiatica on cognitive function and its related properties. The current systematic review includes five randomized controlled trials (RCTs) conducted to determine the effect of C. asiatica alone and six RCTs conducted to determine the effect of C. asiatica-containing products. Meta-analysis indicated that there are no significant differences in all cognitive function domains of C. asiatica when compared to placebo. However, it could improve mood by increasing alert scores [SMD: 0.71 (95% CI; 0.01 to 1.41); I2 = 30.5%] and decreasing anger scores at 1 hour after treatment [SMD: -0.81 (95%CI; -1.51 to -0.09); I2 = 36.6%]. None of the studies reported adverse effects of C. asiatica. In conclusion, there is not strong evidence to support the use of C. asiatica for cognitive function improvement in each cognitive domain. C. asiatica could improve alertness and relieve anger. However, some limitations should be aware including dose regimen, plant preparation, standardization, and product variation. Future well-designed clinical trials using suitable doses of standardized C. asiatica are still needed.

    Semai descriptions of their beliefs about health and disease vary from person to person. Moreover, at different times the same person expresses mutually incongruent beliefs. This amorphousness and fluidity merit analysis rather than neatening. This paper details Semai beliefs, loose ends and all, and suggests that their formal peculiarities are due to the prevalence of synecdoche in conceptual organization. Their inconsistency and fluidity may stem from individualistic egalitarianism within Semai society and powerlessness in the face of nonSemai attack. Finally, it is suggested that construing indigenous medicine as a crude form of Western medicine leads to overtidiness and consequent error.

    BACKGROUND: Assessing communication skills is necessary to facilitate pro-communication skills development programs. The 23-item Communication Scale (CS) is the most widely used tool for this purpose. Since there is a scarcity of validated tools to assess communication skills among Bangladeshi adolescents, we translated this questionnaire into Bangla and validated it on a Bangladeshi adolescent sample.

    METHODS: We conducted two independent rounds of large-scale surveys that yielded data from 621 Bangladeshi adolescents (AgeMean ± SD = 16.44 ± 1.32), of which 378 were males, and 244 were females. The participants completed the Bangla CS. A subset of the participants (n = 160) also completed the Bangla Beck's Hopelessness Scale (BBHS)-a measure of hopelessness.

    RESULTS: Exploratory factor analysis on the first-round data (n = 340) discarded six items and retained 17 items and revealed a unidimensional factor structure. Confirmatory Factor Analysis on the second-round data (n = 281) supported the unidimensional structure (CFI = 0.94, TLI = 0.93). Measurement invariance analysis indicated that the unidimensional structure was robust across gender (143 males vs 139 females). The scale exhibited a negative correlation with BBHS revealing the scale's concurrent validity (r = - 0.16, p  0.70) across a sizable range of communication skills continuum (θ = - 5.3 to 2.3) and had excellent marginal reliability (0.80). All items had adequate discriminating power (0.90 ± 0.20).

    CONCLUSION: The psychometric analysis of the 17-item Bangla-CS indicated that the scale is reliable and valid. We recommend that researchers and mental health practitioners utilize this scale to evaluate communication skills among Bangladeshi adolescents.

    Personal ups and downs are appropriate responses to the ups and downs of life. However, some experiences emotional extremes in moods and disturbed their normal life. Individuals who have depression at times and mania or hypomania at others are called manic-depressive; and the combination is known as manic-depressive psychosis (MDP). This paper attempts to look at manic-depressive psychosis (MDP) from the western approaches as well as from the Islamic point of view. The treatments proposed by both streams are also provided.

    Measures of anxiety in behavioural tests remain largely unclear even decades after their establishment. Differences in the severity of anxiety measured by anxiety tests is an important issue that must be addressed. To test the hypothesis that the addition of light as an aversive stimulus will elicit a difference in behaviour between aged and young animals, we compared the responses of aged and young animals in the home cage emergence test (HCET) and elevated plus maze (EPM), in high aversive bright light and low aversive dim light conditions. In the HCET, our results demonstrated that young animals escaped with shorter latency and greater frequency than aged animals in both bright and dim light conditions, indicating that young animals display greater exploratory tendencies than aged animals. In the EPM, bright light conditions induced anxiogenic effects in both age groups. Interestingly, two-way ANOVA showed a significant interaction effect of age and light on the number of entries into the open arms of the EPM as well as frequency of escape in the HCET. These results show that the addition of light as an aversive stimulus in the EPM and HCET produced different responses in aged versus young animals in each test. In conclusion, significant interactions between age and light affected aged and young animals differently in the HCET and EPM, indicating that the two tests measure different aspects of anxiety.

    Mood profiling has a long history in the field of sport and exercise. Several novel mood profile clusters were identified and described in the literature recently (Parsons-Smith et al., 2017). In the present study, we investigated whether the same clusters were evident in an Italian-language, sport and exercise context. The Italian Mood Scale (ITAMS; Quartiroli et al., 2017) was administered to 950 Italian-speaking sport participants (659 females, 284 males, 7 unspecified; age range = 16-63 year, M = 25.03, SD = 7.62) and seeded k-means clustering methodology applied to the responses. Six distinct mood profiles were identified, termed the iceberg, inverse iceberg, inverse Everest, shark fin, surface, and submerged profiles, which closely resembled those reported among English-speaking participants (Parsons-Smith et al., 2017). Significant differences were found in the distribution of specific mood profiles across gender and age groups. Findings supported the cross-cultural generalizability of the six mood profiles and offer new research avenues into their antecedents, correlates and behavioral consequences in Italian-language contexts.

    Background: Generally, neuropsychiatric patients share different symptoms across nosological categories, such as, amongst other, psychological distress, mood alterations, anxiety, and self-regulation disturbances.ReAttach is a novel psychological intervention with its key elements being external affect and arousal regulation, stimulation of multiple sensory processing, conceptualization, affective mentalization, and associative memory processing. ReAttach has been hypothesized to be effective in reducing symptom severity in different psychiatric conditions. Given the limited information currently available, the present study aimed to investigate the effect of main ReAttach elements called "Wiring Affect with ReAttach" (W.A.R.A.) on negative affect (N.A.), and to compare it with "Distraction," another well-established affect-regulating strategy.

    Methods: We used a single-blind, randomized controlled crossover equivalence design to compare the efficacy on N.A. regulation of W.A.R.A. versus Distraction in 101 patients with different neuropsychiatric disorders.

    Results: The results showed a significant difference (p < 0.001) in response to W.A.R.A. vs. Distraction, with W.A.R.A. being significantly more effective in regulating N.A., with a large effect size (dRMpooled = 2.38) and a high probability (95%) of success.

    Limitations: The heterogeneity of the study population makes generalization and clear recommendations for specific patient groups difficult. The Numeric Rating Scale might have prevented detection of increased N.A. when the baseline scores were high. More in-depth research is needed to explore the W.A.R.A. technique and the extent of confounding variables such as the placebo effect.

    Conclusions: The findings suggest that W.A.R.A. may be an effective, accessible, and brief intervention reducing negative affect. Although premature, these first results are encouraging.

    Objective: Negative affect state toward learning has a substantial impact on the learning process, academic performance, and practice of a particular subject, but such attitude toward electrocardiogram (ECG) learning has still received relatively little attention in medical education research. In spite of the significant emphasis in investigating ECG teaching method, the educators would not be able to address ECG incompetency without understanding the negative perception and attitude toward ECG learning. The purpose of this study was to assess the undergraduate students' difficulties in ECG learning and hence help educators design appropriate ECG learning curriculum to instill competent skill in ECG interpretation based on this outcome.

    Materials and Methods: A total of 324 undergraduate preclinical (year 2) and clinical (year 3-5) medical students participated in this study. The research design used thematic analysis of an open-ended questionnaire to analyze the qualitative data.

    Results: The thematic analysis detected five major emergent themes: lack of remembering (18.2%), lack of understanding (28.4%), difficulty in applying (3.6%), difficulty in analysis (15.1%), and difficulty in interpretation (17.8%), of which addressing these challenges could be taken as a foundation step upon which medical educators put an emphasis on in order to improve ECG teaching and learning.

    Conclusion: Negative attitude toward ECG learning poses a serious threat to acquire competency in ECG interpretation skill. The concept of student's memorizing ECG is not a correct approach; instead, understanding the concept and vector analysis is an elementary key for mastering ECG interpretation skill. The finding of this study sheds light into a better understanding of medical students' deficient points of ECG learning in parallel with taxonomy of cognitive domain and enables the medical teachers to come up with effective and innovative strategies for innovative ECG learning in an undergraduate medical curriculum.

    The present article reports two experiments examining the impact of recollecting emotionally valenced autobiographical memories on subsequent working memory (WM) task performance. Experiment 1 found that negatively valenced recollection significantly disrupted performance on a supra-span spatial WM task. Experiment 2 replicated and extended these findings to a verbal WM task (digit recall), and found that both negative and positive autobiographical recollections had a detrimental effect on verbal WM. In addition, we observed that these disruptive effects were more apparent on early trials, immediately following autobiographical recollection. Overall, these findings show that both positive and negative affect can disrupt WM when the mood-eliciting context is based on autobiographical memories. Furthermore, these results indicate that the emotional disruption of WM can take place across different modalities of WM (verbal and visuo-spatial).

    To develop product portfolios and affective design we need to understand the diversity in user needs. The challenge is how to predict what users want and how they will behave. One approach is to understand user emotions and affective needs, and predict successful product design that can match the needs. This paper discusses affect and its link to cognition. To provide a context, several theories are presented. A framework is described that incorporates characteristics of users, tasks, products, and use environment. The goal is to highlight the importance of emotions in enhancing the value of products. This research field, which we call Hedonomics, is new. There are many challenges in developing valid and reliable measurements of affect, which can influence human factors research as well as design.

    OBJECTIVES: To assess the impact of different types of background music on patients' anxiety and perceptions in a healthcare setting.

    BACKGROUND: An overwhelming number of studies in the West have been conducted on the use of background music in reducing patients' anxiety and their perception of hospitals. Despite the optimism for Western classical music in such settings, evidence documenting the successful use of this genre of music in waiting rooms across other people groups has, thus far, been inconclusive.

    METHOD: A single-blind randomized study in which a total of 303 participants were recruited from both surgery and radiology clinics using a between-groups experimental design. Patients were seated in the waiting room for at least 20 min while music (Western classical, lo-fi) or no music was playing in the background. Participants were then required to complete a questionnaire that consisted of a shortened 6-item State Trait Anxiety Inventory (STAI-6), and eight questions relating to overall perceptions of the hospital.

    RESULTS: The results from both clinics revealed that patients in the no music condition rated themselves as feeling significantly less anxious than those in either of the two music conditions. Patients' perceptions of the hospital's overall service and expectations were higher in the no music condition.

    CONCLUSIONS: Firstly, the choice of background music should match the differing pace of the day; for example, a more upbeat song would better fit the mood of a busy clinic, leading to a more "congruent" atmosphere. Secondly, playing background music in a "task-oriented" and highly charged/anxious environment may increase arousal levels, which in turn could result in negative perceptions of the hospital and an increase in anxiety among patients. Finally, music is a cultural product and music that primes certain beliefs in one culture may not have similar effects among other people groups. Hence, specific curated playlists are necessary to convey "intentions" to different people groups.

    PURPOSE: This study aimed to investigate the relationship between uncertainty in illness and quality of life, and examine the mediating role of coping strategies and mood states in this relationship among breast cancer patients.

    METHODS: A convenience sample of 135 Malaysian women with breast cancer completed questionnaires measuring uncertainty in illness, mood states (i.e. anxiety and depression), quality of life, and copying styles.

    RESULTS: The results showed an inverse correlation between uncertainty and quality of life after controlling for the effects of age, cancer stage and time since diagnosis. Moreover, the negative association between illness uncertainty and quality of life was mediated by coping strategies and mood states.

    CONCLUSION: The findings revealed that breast cancer patients experiencing a high level of uncertainty more likely use avoidant and less likely use active emotional coping strategies which in turn amplifies anxiety and depression and undermines their quality of life. While some interventions to reduce the adverse consequences of uncertainty are recommended, the findings indicated the need for targeted psychological interventions seeking to gradually shift cancer patients' coping strategies from avoidant to active emotional coping.

    Workplace architectural lighting conditions that are biologically dim during the day are causing healthy individuals to experience light-induced health and performance-related problems. Dynamic lighting was reported beneficial in supporting individuals' psychological behavior and physiological responses during work period in Europe. It has yet to be investigated in workplaces with minimal/no natural daylight contribution in tropical Malaysia. Hence, an exploratory experimental study was initiated in an experimental windowless open-plan workplace in Universiti Putra Malaysia, Serdang. The aim was to identify dynamic lighting configurations that were more supportive of a morning boosting effect than the control constant lighting, to support dayshift individuals' psychophysiological wellbeing indicators during the peak morning work period. The immediate impact of a 2-hour morning exposure to overhead white LED (6500 K) with different horizontal illuminance levels and oscillations (lighting patterns) were investigated on physiological indicator limited to urinary 6-sulfatoxymelatonin, and psychological indicators for alertness, mood, visual comfort, cognitive and visual task performance. Not all of the investigated dynamic lighting configurations were supportive of a morning boost. Only configurations 500increased to750 and 500increased to1000 lx therapeutically supported most of the indicators. Both these configurations suppressed urinary 6-sulfatoxymelatonin, and improved alertness, cognitive performance, positive affect, and visual comfort better than 'visit 1: 500constant500' lx (control). The increasing oscillation was observed more beneficial for the morning boost in tropical Malaysia, which is in reverse to that specified in the human rhythmic dynamic lighting protocol developed by researchers from the Netherlands for application during winter. The findings from this study present the feasibility of dynamic architectural lighting acting as an environmental therapeutic solution in supporting the individuals' psychophysiological wellbeing indicators in windowless open-plan workplace in tropical Malaysia. Further investigations on the two prospective configurations are recommended to determine the better supportive one for the morning boosting effect in Malaysia.
