While sustainable diets are widely acknowledged for their ecological benefits, the interplay of social-emotional factors shaping such choices remained relatively underexplored. This study explored the interplay between guilt proneness, emotional support from best friends, and open- mindedness and their influence on young adults’ pro-environmental dietary choices. These variables were selected for their distinct impacts on decision-making processes and behavioural intentions, as guilt proneness motivates alignment with moral values, emotional support provides social reinforcement and validation, and open-mindedness encourages adoption of atypical diets. Plant-based diets involve (mostly) excluding meat including variations like flexitarian and pescetarian diets, while vegetarian diets exclude meat, and vegan diets exclude meat and animal-derived foods and products. The dietary choices in this study rank from the least to the most sustainable diet, being omnivores, plant-based, vegetarian, and ultimately, vegan. The cross-sectional design incorporated 213 individuals aged 17 to 26 from multiple genders and nationalities. The multiple stages assessment included a 45-minute online survey that employed specific tests to assess the factors. Dietary choice was assessed using the Dietarian Identity Questionnaire, guilt proneness using the Test of Self-Conscious Affect–3, emotional support from best friends using the Official short version of the Network Relationship Inventory, and open-mindedness using the Big Five Inventory-2. The multiple regression analyses indicated that guilt proneness, emotional support from best friend, open-mindedness, and the three-way interaction of these variables were non-significant predictors of dietary choice. These results diverged from initial hypotheses, emphasizing the need for exploration within different contexts and populations. The study's strengths included its cross-sectional design encompassing multiple nationalities and genders, and the thorough validation of statistical assumptions. However, the questionable to low reliability of some measures and the unequal gender distribution possibly affected the generalizability of the findings. Additional factors that may influence dietary choices among young adults, including cultural norms, socioeconomic status, anticipated pride, and peer influence, should be incorporated in future research. Interventions aimed at promoting pro- environmental dietary choices among young adults must adopt a holistic approach, considering individual, social, and environmental factors to facilitate long-term behaviour change.Show less

It is important that they get support to get financially back on track. However, they often refrain from seeking help, likely due to the shame associated with their financial situation (Keizer, 2016; Plantinga, 2019). This shame hinders their ability to adopt problem-focused coping strategies and consequently improve their financial circumstances (De Hooge et al., 2010). However, shame resilience shows a promising role in addressing this issue. It involves reducing feelings of entrapment, powerlessness, and isolation, thereby managing feelings of shame in a way so that enables people to effectively deal with their situation (Brown, 2006). This study investigates the effectiveness of shame resilience interventions in increasing communication between creditors and debtors. We conducted an experiment involving participants in debt and manipulated creditor letters to increase shame resilience. Results indicate that shame resilience interventions significantly increase willingness to contact creditors and improve the perceived trustworthiness of the company. These findings suggest that applying shame resilience interventions can assist people in taking the first step toward seeking help to address their debt.Show less

Benedict Anderson emphasizes this importance in his theory of an “Imagined Political Community”, whereby a subconscious feeling of belonging is needed within a group in order to establish the existence and continuation of a nation. However, this feeling of belonging is not automatically established, but requires the help of several concepts that can define an identity. Language, culture and history can be seen as three overarching concepts that aid in the feeling of belonging, thereby aiding in the construction of a nation identity felt within a nation. Oftentimes, the state within a nation makes use of these concepts to further emphasize the way its population should feel connected to their nation, and thereby the state. However, while looking at Arab states, entire populations do not necessarily align with state-led views, allowing for the formation of minorities. Two such minorities within Arab states are the Swahili speaking Zinjibaris in Oman and the Nubians in Egypt. While differing in history, as the Zinjibaris have only been present in Oman since the 1960s, and the Nubians since the pharaonic era, each minority is still able to find themselves as minorities within an Arab majority. This thesis thereby focuses on the extent to which each of these minorities aligns themselves with the state-led views on national identity and that of the majority population of each respective country. Each of the minorities is able to negotiate and construct their national identities within the framework of state-led national identity formation in different ways. Keeping the concepts language, culture and history in mind, the Zinjibaris are able to find themselves in the state’s perspective of a culturally diverse Omani national identity. In contrast, the Nubians are not able to find themselves within the Egyptian state-led views of a religiously diverse country, whereby Nubian heritage preservation takes the primary role in the Nubian perspective of national identity. Thus, portraying the difference in the way minorities are able to feel a sense of belonging in their countries of residence.Show less

However, their influence on defensive responses to threat has yet to be investigated. This study examines whether a placebo manipulation can impact subjective pain ratings in response to the shock, as well as heart rate during shock anticipation, in healthy individuals. Participants (n=72) were tested in a Pavlovian threat conditioning paradigm over two days with a 24-hour interval, in a within-subject design. A sham analgesic electrical stimulation (TENS) was used to induce a placebo effect. The placebo conditioning process paired a placebo stimulus ("painful shock + TENS") with a low pain response, followed by two sessions of associative threat conditioning. Subjective pain ratings and heart rate, as an indicator of the freezing response, were measured across different conditions. The STAI-trait questionnaire was also completed. Results indicated higher subjective pain levels in response to the painful shock compared to the TENS shock during the threat acquisition phase. Importantly, during this phase, stronger heart rate deceleration, indicative of freezing, was observed when anticipating the painful shock versus the TENS shock. There was no evidence the placebo effect persisted during the threat retention stage, as there were no significant differences in heart rate while anticipating the two conditions. Trait anxiety did not significantly influence the placebo response. These findings demonstrate that a placebo intervention affects not only subjective experiences but also physiological responses to threat, highlighting the potential of using placebos as co-interventions for individuals experiencing anxiety.Show less

To address this effectively, it’s important to understand to what extend factors such as academic stress, parental expectations and family well-being influence the development of anxiety and mood disorders. Relatively little is known about the anxiety and worry experienced by early adolescent children and the extent to which this is culture dependent. The present study sought insight in the worries of children aged 10-12 years from Western and non-Western cultural backgrounds. In addition, the extent to which internalizing symptoms are related to achievement anxiety, parental expectations and family well-being was examined. This was done by interviewing 74 Indian children (M = 10.92 ; SD = 0.75) and 69 Dutch (M = 11.17 ; SD = 0.92) children using the Cultural Formulation Interview. In addition, the amount of internalizing complaints and family welfare were determined using RCADS and FASIII. Results showed that children from India more often experienced achievement-oriented anxiety than Dutch children, and that this was associated with a greater amount of internalizing symptoms. The parental expectations that Indian children experienced were often achievement-oriented expectations regarding school or future profession, whereas the parental expectations of Dutch children were more often focused on being able to show responsibility for tasks. This might be explained by the values transmitted from parent to child within individualistic and collectivistic culture. Evidence exists that cultural values remain present when families from collectivist cultures move to a country with a more individualistic culture. It is therefore extremely important to be aware of these cross-cultural differences within mental health care, as well as education, when dealing with adolescents with anxiety and mood problems.Show less

It is hypothesized that exercise of moderate and high intensity enhance creativity more effectively than exercise of lower intensity. The study also investigates if arousal, positive high-arousal affect, and negative high-arousal affect serve as intermediary variables in this relationship. Scarce previous research has suggested a relationship between exercise-intensity and creativity, but studies comparing different exercise-intensities on creativity and potential underlying mechanisms were lacking. To address this knowledge gap, this study compares different intensities, namely low-intensity (cycling at 55% of maximum heart rate), moderate-intensity (cycling at 70% of maximum heart rate), high-intensity (cycling at 85% of maximum heart rate) and a control group, on divergent creativity (i.e., number and uniqueness of creative ideas); And looks at affect and arousal as underlying mechanisms. Happy (positive), elated (positive), upset (negative), tense (negative) and stressed (negative) are used as indicators for high-arousal affect and feelings of wakefulness and alertness as indicators for arousal. Participants in this study completed two appointments, of which the first appointment consisted of a fitness test to measure participants’ maximum heart rate. During the second appointment, participants were randomly assigned to one of the four conditions and their affect and arousal were measured before and after the exercise or control task. Creativity was measured after the exercise or control task was completed. A Kruskal-Wallis Test showed that participants in the moderate-intensity and high-intensity exercise did not show higher creativity. Further, macro PROCESS model 4 revealed a significant effect of moderate-intensity and high-intensity exercise on arousal in comparison to low-intensity exercise and a significant effect of moderate-intensity exercise on positive high-arousal affect, in comparison to the control group. Other than this, the model revealed that none of the mediators significantly explained a relationship between exercise-intensity and creativity. This study thus suggests that exercise-intensity does not play a significant role in creativity enhancement, nor does arousal or high-arousal affect. However, future research is needed to confirm this for other modes of exercise, regular exercise instead of acute bouts of exercise and for different individual characteristics, such as age and gender.Show less

While TMS appears promising for stroke rehabilitation, there is variability in the level of improvement individuals exhibit. This variability may be attributed to oscillatory neurophysiology, which refers to the rhythmic electrical activity of the brain. Therefore, this study investigated phase-dependent changes in cortical excitability after TMS among stroke patients in affected and unaffected hemispheres. We investigated motor-evoked and TMS-evoked potentials at four phases of the ongoing motor cortical mu rhythm (trough, peak, rising, falling) in both hemispheres (affected, unaffected). Participants comprised N=11 chronic subcortical stroke patients (6 female, mean ± std age: 58 y ± 11.4) with affected lateralized upper-limb impairment. Four blocks of 150 TMS pulses were applied on each hemisphere, targeting the primary motor hotspot of the first dorsal interosseus muscle of the contralateral hand. Participants watched nature videos during stimulation to maintain consistent attention levels. Cortical excitability was assessed by analyzing motor-evoked potentials (MEP) and TMS-evoked potentials (TEP). Results showed that motor responses (measured through MEP amplitudes) were significantly larger at the trough and rising phase compared to the peak phase. No significant differences were observed between the affected and unaffected hemispheres. TEP components, the brain signals in response to TMS, did not exhibit significant phase-dependent changes. While our findings showed a nonsignificant effect of stroke severity, exploratory correlation analyses presented a positive association between higher remaining movement function and enhanced phase-dependent responses to TMS. The findings build upon previous research indicating phase-dependent changes in cortical excitability for MEPs but not for TEPs. The larger MEP amplitudes during trough and rising phases suggest that TMS can be more effective at specific points of cortical activity. Further exploration is needed to assess the efficacy of phase-specific TMS interventions in clinical settings, potentially through larger-scale clinical trials with longitudinal designs and comparative effectiveness studies, aiming to evaluate functional outcomes and determine their impact on motor recovery.Show less
