An Agonistic Model of Dialogue

In this article, Schellhammer's statements that learning is only possible in tension and that difference and diversity are prerequisites for tension are discussed in light of a certain event that occurred at a Summer School on Pluralism, Development, and Social Change. The article aims to explore Bildung, and especially learning in tension, through a concrete case study in which cultural diversity is a key issue. Reflecting on the case, psychological, philosophical, and sociopolitical perspectives are presented, each of which casts a different light on what happened. In the final reflection, we turn to the question of what dialogical self theory (DST) can offer when it comes to learning in tension, and how DST can be enriched and challenged by other approaches. We argue that DST facilitates the development of intercultural competence through dialogue with the unknown other in the self. Philosophical notions of cosmopolitanism and Socratic self-examination can shed further light on resistance to and conditions for transformative dialogues. They also place these in a historical and global perspective. We introduce an agonistic model of dialogue, in which the structural power inequalities and privileges people bring into dialogical spaces are explicitly addressed, thereby sowing the seeds of postdialogue transformative action in a personal and professional sense—for example, in transformative justice initiatives.     

Mindfulness and psychological distress in men during the COVID-19 pandemic: The mediating role of environmental mastery and purpose in life

Men's mental health has been severely affected during the COVID-19 pandemic, with many studies focussing on the determinants of men's psychological distress. This study aimed at examining the relationships between mindfulness, environmental mastery (EM), purpose in life (PL) and indicators of psychological distress (i.e., common mental disorders and perceived stress). This was a cross-sectional online study in which participants were 1,006 men aged between 29 and 39 years (45.1%), residing in Brazil during the first wave of the COVID-19 pandemic. A parallel multiple mediator model was used to test the study variables' relationships, using mindfulness as the independent variable and indicators of psychological distress as the dependent variables. Results indicated that EM and PL significantly mediated the effects of mindfulness on men's psychological distress, lowering its levels and accounting for 31% of common mental disorders and 51% of perceived stress. Implications for public health policies and clinical practice are discussed.     

Computerized stroop test to assess selective attention in children with attention deficit hyperactivity disorder

Research shows abnormal function of the pre-frontal cortex in Attention Deficit Hyperactivity Disorder (ADHD). This cortex is involved in the control of executive functions related to planning and execution of goal-oriented strategies, working memory, inhibitions, cognitive flexibility, and selective attention. Selective attention involves focus on the target stimulus, ignoring competing distractions. The Stroop Test (Stroop, 1935) is usually used to evaluate selective attention. This study investigated whether children with ADHD could exhibit modified performance in the Stroop Test. Using a computerized version of this test (Capovilla, Montiel, Macedo, & Charin, 2005), the study compared the reaction times (RTs) of 62 Brazilian children, between 8 and 12 years of age, 31 of whom were diagnosed with ADHD and sent to psychiatric clinics, and 31 without ADHD studying in regular schools. All children with ADHD satisfied the criteria of the DSM-IV-TR and were evaluated with the Conners Abbreviated Questionnaire (Goyette, Conners, & Ulrich, 1978), completed by parents and teachers. The results revealed that children with ADHD exhibit greater interference in RT than children without ADHD. This corroborated the hypothesis that children with ADHD exhibit a deficit in selective attention, consisting in augmented RTs, as measured by the Computerized Stroop Test.     

Does Maternal Prenatal Stress Adversely Affect the Child’s Learning and Memory at Age Six?

Prenatal maternal stress has been shown to affect postnatal development in animals and humans. In animals, the morphology and function of the offspring’s hippocampus is negatively affected by prenatal maternal stress. The present study prospectively investigated the influence of prenatal maternal stress on learning and memory of 112 children (50 boys, 62 girls, Age: M=6.7 years, SD=8.4 months), with the Test of Memory and Learning (TOMAL). Maternal stress levels were determined three times during pregnancy by self-report questionnaires. Furthermore, maternal saliva cortisol samples were used as a measure of hypothalamus-pituitary-adrenal axis functioning. Results of hierarchical multivariate regression analyses showed that maternal life events measured during the first part of pregnancy were negatively associated with the child’s attention/concentration index, while controlling for overall IQ, gender, and postnatal stress. No associations were found between prenatal maternal cortisol and the offspring’s learning and memory.     

Long-term musical training may improve different forms of visual attention ability

Many studies have suggested that structural and functional cerebral neuroplastic processes result from long-term musical training, which in turn may produce cognitive differences between musicians and non-musicians. We aimed to investigate whether intensive, long-term musical practice is associated with improvements in three different forms of visual attention ability: selective, divided and sustained attention. Musicians from symphony orchestras (n = 38) and non-musicians (n = 38), who were comparable in age, gender and education, were submitted to three neuropsychological tests, measuring reaction time and accuracy. Musicians showed better performance relative to non-musicians on four variables of the three visual attention tests, and such an advantage could not solely be explained by better sensorimotor integration. Moreover, in the group of musicians, significant correlations were observed between the age at the commencement of musical studies and reaction time in all visual attention tests. The results suggest that musicians present augmented ability in different forms of visual attention, thus illustrating the possible cognitive benefits of long-term musical training.     

Quality of life of patients with amyotrophic lateral sclerosis

The aim of this study is to evaluate the correlation between different measures of quality of life (QoL), functional status and mood status in patients with amyotrophic lateral sclerosis (ALS). A sample of 40 patients with ALS was recruited and scales for the evaluation of health-related QoL (SF36), patient-centered QoL (SEIQoL), functional status (ALSFRS) and depression (ZDS) have been administered to them. All the correlations (Pearson's r) between the scores have been considered and the t-test was performed in order to compare male with female patients. No correlation emerged between the different measures of QoL and functional status, apart from the scores of the Physical Functioning subscale of the SF36 which resulted positively correlated (p?相似文献   

The impact of cortisol reactivity to acute stress on memory: sex differences in middle-aged people

Stress has been identified as a main factor involved in the cognitive changes that occur during the aging process. This study investigated sex differences in the relationship between the magnitude of the acute stress-induced salivary cortisol response and memory performance among middle-aged people. To this end, 16 men and 16 women (aged 54-72 years) were exposed to the Trier Social Stress Test and a control condition in a crossover design. Afterwards their memory performance was measured using a standardized memory test (Rey's Auditory Verbal Learning Test). Only among women, there was an acute impact of stress on memory performance and a significant relationship between a higher cortisol response to the stressor and poorer memory performance in both the stress and control conditions. Additionally, a poorer memory performance was related to earlier timing of sexual maturation (age at menarche), which was also marginally related to higher cortisol reactivity to stress. These results confirm that sex is a critical factor in the relationship between cortisol and poor memory performance. Furthermore, the findings emphasize a strong link between the individual cortisol response to stress and memory functioning among postmenopausal women.
