RESUMO

The study aimed to investigate the effects of an embodied mindfulness treatment on chronometric mental rotation. Forty-four women and 47 men participated and were randomly divided into two groups: a mindfulness induction group and a control group. They completed two sets of 150 mental rotation tasks with cube figures each. Subjective cognitive effort (measured after each block), reaction time, and accuracy were analyzed using linear mixed models with the factors of time, mindfulness, angular disparity, and gender. The significant finding was a three-way interaction between pre-post testing, mindfulness, and gender for reaction times. This interaction suggests that women might benefit more from the mindfulness induction, while men may benefit more from the control condition. The analysis of subjective cognitive effort indicates that women and men perceive the same cognitive effort when solving cube-figure tasks.

RESUMO

OBJECTIVES: The aim of this study was to investigate the impact of a mindfulness intervention (IG) compared to an inactive control group (CG) on explicit and implicit attitudes toward vegetarian and meat-based foods, nutrition behavior measures, trait mindfulness and wellbeing. METHODS: In the IG (N = 66), we implemented a mindfulness-based intervention consisting of eight weekly group sessions online, along with an additional half-day session held on campus. The CG (N = 71) received no intervention or training. We employed a pre-/post-intervention design involving questionnaires (trait mindfulness, wellbeing, sustainable nutrition behavior scale), an online supermarket scenario, as well as an explicit rating task and an implicit association task using pictures of vegetarian and meat-based foods. Additionally, a voluntary follow-up testing was conducted two months after the final group session. RESULTS: No intervention effects were observed on explicit and implicit attitudes, wellbeing, or nutrition behavior measures. However, there was an increase in trait mindfulness within the IG. Exploratory cross-sectional findings indicated that trait mindfulness facets such as "Acting with Awareness" and "Outer Awareness", along with explicit attitudes, were significant predictors of self-reported sustainable consumption behavior. Additionally, sex and explicit attitudes were identified as significant predictors of vegetarian consumption behavior in the online supermarket task. CONCLUSION: Our findings could not substantiate previous claims regarding the potential causal effects of mindfulness practice on sustainable consumption behavior, specifically in the realm of sustainable and vegetarian nutrition, as well as subjective wellbeing. Future studies may benefit from implementing longer-term mindfulness-based interventions and considering other potential decisive factors, such as connectedness to nature and others. Integrating training elements focusing on these specific variables into the intervention could be valuable.

RESUMO

The sense of agency varies as a function of arousal in negative emotional contexts. As yet, it is unknown whether the same is true for positive affect, and how inter-individual characteristics might predict these effects. Temporal binding, an implicit measure of the sense of agency, was measured in 59 participants before and after watching either an emotionally neutral film clip or a positive film clip with high or low arousal. Analyses included participants' individual differences in subjective affective ratings, physiological arousal (pupillometry, skin conductance, heart rate), striatal dopamine levels via eye blink rates, and psychopathy. Linear mixed models showed that sexual arousal decreased temporal binding whereas calm pleasure had no facilitation effect on binding. Striatal dopamine levels were positively linked whereas subjective and physiological arousal may be negatively associated with binding towards actions. Psychopathic traits reduced the effect of high arousal on binding towards actions. These results provide evidence that individual differences influence the extent to which the temporal binding is affected by high arousing states with positive valence.

RESUMO

Diagnosis and therapy of esophageal carcinoma is challenging and requires a multidisciplinary approach. The purpose of the updated German guideline "Diagnosis and Treatment of Squamous Cell Carcinoma and Adenocarcinoma of the Esophagus-version 3.1" is to provide practical and evidence-based advice for the management of patients with esophageal cancer. Recommendations were developed by a multidisciplinary expert panel based on an extensive and systematic evaluation of the published medical literature and the application of well-established methodologies (e.g. Oxford evidence grading scheme, grading of recommendations). Accurate diagnostic evaluation of the primary tumor as well as lymph node and distant metastases is required in order to guide patients to a stage-appropriate therapy after the initial diagnosis of esophageal cancer. In high-grade intraepithelial neoplasia or mucosal carcinoma endoscopic resection shall be performed. Whether endoscopic resection is the definitive therapeutic measure depends on the histopathological evaluation of the resection specimen. Esophagectomy should be performed minimally invasive or in combination with open procedures (hybrid technique). Because the prognosis in locally advanced esophageal carcinoma is poor with surgery alone, multimodality therapy is recommended. In locally advanced adenocarcinomas of the esophagus or esophagogastric junction, perioperative chemotherapy or preoperative radiochemotherapy should be administered. In locally advanced squamous cell carcinomas of the esophagus, preoperative radiochemotherapy followed by complete resection or definitive radiochemotherapy without surgery should be performed. In the case of residual tumor in the resection specimen after neoadjuvant radiochemotherapy and R0 resection of squamous cell carcinoma or adenocarcinoma, adjuvant immunotherapy with nivolumab should be given. Systemic palliative treatment options (chemotherapy, chemotherapy plus immunotherapy, immunotherapy alone) in unresectable or metastastic esophageal cancer depend on histology and are stratified according to PD-L1 and/or Her2 expression.

RESUMO

Embodied mental rotation is the influence of the body on mental rotation ability. Sports expertise enhances embodied mental rotation ability. However, sport-skill-dependent effects remain unclear. Previous studies refer to the influence of body positions on mental rotation ability. Yet, in sports, the investigation of the effect of simultaneous body and mental rotation movements is essential. Athletes need to constantly mentally and physically adapt to environmental changes and new motor tasks while being in motion themselves. This study aimed to investigate embodied mental rotation ability with simultaneous body and mental rotation in individuals with different sport skills, i.e., in open- and closed-skill sports. Forty-eight men and women, divided into two groups depending on their sport, performed 32 trials of an extended embodied mental rotation task. Simultaneous body and mental rotation were enabled by a novel test method including Virtual Reality. Results revealed shorter response times to the task stimulus in closed-skill sports participants than in open-skill sports participants. This group difference was significant for trials in which rotation directions of the own body and the mental rotation stimulus were aligned. The results might be related to sport-specific skill development processes. Motor imitation skills, as relevant in many closed-skill sports, may facilitate cognitive processes when the motion direction of the own body and of the mental rotation stimulus are aligned. The novel test method identifies potential applications that should be increasingly explored in the future, both for cognitive science and sports research.

RESUMO

Introduction: Using the morality salience paradigm, this research tested whether subliminal death stimuli lead to increased physical strength. Moreover, it was investigated if mindfulness and self-esteem instability influence terror management. Methods: In total, data from 160 undergraduate sports students were analyzed. Participants completed a word decision task in which they were presented with either the word death or pain for 28.5 ms. Before and after the task, their grip strength was measured using a hand dynamometer. Results: Linear mixed models could neither confirm the effect of the mortality salience hypothesis on strength nor an influence of mindfulness and self-esteem. Discussion: The results raise the question of a potential influence of subliminal mortality salience on athletic performance and how mindfulness and self-esteem instability affect terror management.

RESUMO

Internal transformative qualities are essential contributing factors to sustainable behavior. Besides awareness, insight, purpose, and agency, connectedness is one of those inner qualities. In this study, we investigated the relationship between connectedness to oneself (self-love), towards the environment (connectedness to nature), towards other human beings (pro-socialness), and sustainable behavior towards clothes and food. One hundred thirty-nine mostly students participated. The results showed that self-love, connectedness to nature, and pro-socialness correlate. Sustainability behavior towards food was predicted by pro-socialness, the choice of diet, and environmental and ethical reasons for nutrition. Sustainable behavior towards clothes was predicted by connectedness to nature. This study hints that the factors of inner transformative qualities and the type of sustainable behavior must be investigated differently. It strengthens the multi-facet dimensions of sustainable behavior.
