IntroductionDuring mental rotation tasks, it is assumed that participants visualize a rotation of objects in their minds (internal visualization), but mental rotation has also been linked to the visible rotation of objects on a screen (external visualization). The angular disparity in mental rotation also influences postural sway, the movements of the body center. Postural sway is thus suspected as one type of indirect measurement of the rotation process. We compare the external visualization of rotation with the suspected internal visualization during mental rotation tasks. We suspect both are similar and thus produce a comparable effect on postural sway.MethodsOne hundred and fifty participants completed three rotation tasks with cube figures, two of which were aided by external visualization. Their center of pressure was measured throughout. The effects of external visualization, angular disparity, and their interaction on postural sway were compared using Bayesian statistics and a decision boundary of 3 or 1/3.Results and discussionThe results indicate no differences between conditions for all postural sway parameters. We observe differences between conditions in cognitive load and reaction time. However, as these partially also differ between the two external visualization conditions and do not transfer to differences between the postural sway parameters, the underlying processes in the three conditions are likely similar. Our results support the notion that the visualization of rotation is central to postural sway during mental rotation. This further supports that the rotation process of the external visualization and mental rotation are similar and thus that stimuli are indeed rotated mentally during mental rotation tasks. Our results further support that the common process between mental and manual rotation lies in the visualization instead of mental rotation being an imagined motor action. Because visual control and feedback play an essential role in many motor tasks, the results could also be of further interest for a more general link between motor and cognitive tasks and bidirectional benefits through the construction of visual similarities.

This study investigated the relationship between mental rotation ability and postural stability, with a focus on the role of the visuospatial sketchpad of working memory, as it has been found to be correlated with both concepts. A total of 87 healthy young adults completed a postural stability task on a force plate, a mental rotation task, and both spatial and object working memory tasks in a counterbalanced order. Bayesian correlations revealed weak positive correlations between mental rotation and postural stability, as well as a correlation between mental rotation and spatial working memory. A weak association was also observed between mental rotation and object working memory. No correlation was found between the working memory components and postural stability. Furthermore, the results showed that spatial working memory did not play a crucial role in predicting postural stability. We conclude that the visuospatial sketchpad, particularly the spatial working memory component, cannot explain the relationship between mental rotation and postural stability.

Main goal of this study was to investigate the influence of mental rotation tasks on postural stability. 84 participants were tested with two object-based mental rotation tasks (cube vs. human figures), an egocentric mental rotation task with one human figure, a math- (cognitive control) and a neutral task, while standing on a force plate in a both-legged narrow stance. Parameters related to the Center of Pressure course over time were used to quantify postural stability. The simultaneous solution of mental rotation tasks has led to postural stabilisation compared to the neutral condition. Egocentric tasks provoked more postural stability than object-based tasks with cube figures. Furthermore, a more stable stance was observed for embodied stimuli than for cube figures. An explorative approach showed the tendency that higher rotation angles of the object-based mental rotation task stimuli lead to more postural sway. These results contribute to a better understanding of the interaction between mental rotation and motor skills and emphasize the role of type of task and embodiment in dual task research.

Soccer is one of the sports activities, where stereotypes against women are still quite common. Also, participation is lower for women in a male-stereotyped sport. One possible explanation might be different attitudes toward female and male athletes in a male-stereotyped sport. It is the main goal of this study to investigate if male soccer players are rated more positively compared to female soccer players. 176 participants (100 cisgender women and 76 cisgender men) completed an explicit and implicit affective rating task and a self-compassion questionnaire. The results showed an own-gender bias in the explicit rating task. In the implicit affective rating task, female soccer players were evaluated more positively than male soccer players, independent of the own gender. Besides, self-compassion was related to the affective evaluations. Explicit and implicit affective ratings did not correlate. According to the implicit and explicit ratings found in this study, we suggest that it is unlikely that implicit affective evaluations are the underlying mechanism of stereotypes in soccer. However, we did not examine the relation of implicit evaluations to stereotypes in sports performance. Therefore, further studies should be conducted to investigate those effects, as well as the impact of other influencing variables on stereotypes against women and female participation in a gender-stereotyped sports activity.

The effect of different human body part stimuli in mental rotation tasks (MRTs) on postural stability was investigated in two dual-task experiments. There were significant differences within egocentric MRTs (Experiment 1, N = 46): Hand and foot stimuli tended to cause more body sway than whole-body figures and showed increased body sway for higher rotation angles in the MRTs. In object-based MRTs (Experiment 2, N = 109) different stimuli did not evoke different levels of body sway, but higher rotation angles led to higher body sway. Both experiments showed a stabilizing effect of MRTs compared to the control condition. Exploratorily analyses identified reaction time in MRTs as a significant predictor of body sway. The results suggest a heterogeneous impact of mental rotation on postural stability.

In these times of intense political debate about climate change, it is more important than ever to understand which factors are central to adopting environmentally friendly behavior, such as buying an electric car instead of a conventional one. The stage model of self-regulated behavioral change (SSBC) offers a promising explanatory approach in which explicit attitudes, which are connected to factors such as mindfulness, play an essential role. So far, the role of implicit attitudes regarding environmental behavior was neglected in this model. Accordingly, the present study investigated if the (goal) intention to buy an electric car can be predicted by established variables like explicit attitudes, personal and social norms, and the perceived usefulness of electric vehicles and implicit attitudes. Besides, it was investigated if attitudes depend on socio-demographic variables and mindfulness aspects. For this purpose, 168 participants completed questionnaires and performed an explicit rating and an implicit affective priming task with pictures of electric vs. conventional cars. The results showed that while explicitly, electric cars were rated more positively, implicitly, this difference could not be shown. Furthermore, mindfulness was not significantly associated with attitudes or goal intention. However, goal intention was significantly predicted by explicit and implicit attitudes, personal norms, and perceived usefulness, while explicit attitudes mediated the effects of the last two variables. Accordingly, we concluded that implicit attitudes should be integrated into existing models of behavioral change and further predictors need to be identified.

In this study, the affective explicit and implicit attitudes toward electric and gasoline cars are investigated. One hundred sixty-five participants (103 cisgender women, 62 cisgender men) completed an explicit and implicit affective rating task toward pictures of electric and gasoline cars, measurements of sustainability, future and past behaviors, and mindfulness. The results showed a positive emotional attitude for the electric cars compared with the gasoline cars only for the explicit rating but not for the implicit one. Furthermore, factors that correlated to the attitudes were investigated: explicit ratings in car owners correlated with age, degree, sustainability in general, and the expressed intention to purchase an electric car in the future. Implicit attitudes in car owners correlated with the overall score of mindfulness and the dimension of “non-reactivity.” For the non-car owners, explicit attitudes correlated with the expressed intention to purchase an electric car in the future and the mindfulness dimension of “describing”. In this group, the implicit attitude correlated negatively with the mindfulness intention of acting with awareness. This indicates that several different factors should be considered in the development of promotion campaigns for the advantage of sustainable mobility behavior.

The coronavirus pandemic has a high impact on mental health, as for example, anxiety. It was the main goal of this study to investigate if rumination and worry mediate the possible relation of self-compassion and fear of the future in females and males of three European and three Middle Eastern countries during the coronavirus pandemic. 2765 men and women participated and answered questions regarding their fear of the future on the one hand and completed the reflection-rumination questionnaire, the Penn-state worry questionnaire, and the self-compassion scale. The results of a mediation analysis demonstrated a relation between self-compassion and fear of the future, which was mediated by worry but not by rumination, independent of gender and country. Furthermore, the fear of the future variable was predicted by different factors in each country. The only clear difference between the participants of the European and the Middle Eastern countries was that women show more fear of the future only in the European countries but not in the Middle Eastern countries. However, there were also differences between the three European and the three Middle Eastern countries. The results indicate that in general, psychological consequences of the coronavirus pandemic should be investigated for each country separately. It does not to seem possible to infer results from one country to another country even on the same continent.

Implicit and explicit attitudes influence our behavior. Accordingly, it was the main goal of the paper to investigate if those attitudes are related to body image satisfaction. 134 young women between 18 and 34 years completed an explicit affective rating and an implicit affective priming task with pictures of women with different BMIs. Because it is well known that mindfulness, self-compassion and social media activity influence body image satisfaction, these variables were registered as well. The results confirmed an explicit positive affective bias toward pictures of slim women and a negative bias toward emaciated and obese body pictures. It adds to the literature that the explicit positive bias does not hold true for the strongest form of underweight, suggesting that instead of dividing different body shapes into two groups, different gradings of under- and overweight should be considered. Concerning the affective priming task, no significant differences between the different pictures could be carved out. Implicit and explicit affective attitudes were not related to the body satisfaction of the participating women. In line with former studies, body satisfaction was predicted by the actual-ideal weight discrepancy, the BMI, aspects of mindfulness and self-compassion. This study indicates that implicit and explicit affective attitudes toward underweight and overweight women are unrelated to the participants' body satisfaction.
