The neural bases of sport fan reactions to teams: Evidence from a neuroimaging study

This study uses neuroimaging methods to identify patterns of brain activation among sport fans in reaction to team stimuli. In a whole-brain analysis without selected regions in advance, the purposes were to identify the structures involved when fans are exposed to positive, neutral, and negative events and to learn what events activate more limbic networks. A total of 53 individuals participated in and functional magnetic resonance imaging experiment involving the presentation of videos in various situations. Findings indicate the activation of the cingulate gyrus and other structures of the limbic system, as the hippocampus and parahippocampus. We also found involvement of the ventral tegmental area of the reward system. Additionally, brain activity in emotional regulation and memory areas were more influenced by positive than neutral and negative videos. It was also found the involvement of other areas not directly included in the limbic or reward systems. This study provides the neural basis of fan reactions to team-related stimuli. Sport clubs should be aware that negative content seems to be suppressed from emotional memory and positive videos trigger more emotion and memory areas than neutral and negative videos.     

The Origins of Fears of Compassion: Shame and Lack of Safeness Memories,Fears of Compassion and Psychopathology

Empirical and clinical research suggests that some individuals find self-generating compassion and receiving compassion from others difficult and aversive. However, it is unclear how these fears of compassion are linked to early experiences and to psychopathological symptoms. This study explores the relationship between shame traumatic memories, centrality of shame memories, early memories of warmth and safeness, fears of compassion, and depression, anxiety and paranoid symptoms. Participants were 302 individuals from the general community population, who completed self-report measures of fears of compassion, shame memories, early affiliative memories, and psychopathology. Shame traumatic and central memories were positively associated with fears of compassion for self, for others and from others, whereas early memories of warmth and safeness were negatively related to such fears. Path analyses revealed that fears of compassion for self and of receiving compassion from others mediated the effects of shame traumatic memory, centrality of shame memory and early memories of warmth and safeness on depressive, anxious and paranoid symptoms. These findings have implications for therapeutic interventions as these fears, as well as the negative shame-based emotional memories fuelling them, may need to be addressed in therapy to assist patients in self-generating and receiving compassion.     

Can Self-Reassurance Buffer against the Impact of Bullying? Effects on Body Shame and Disordered Eating in Adolescence

Bullying experiences are associated with body image and eating-related problems. Nonetheless, research on possible resilience factors is scant. The current study tested a path model examining the association between emotional memories of experiences of warmth and safeness, and self-reassuring abilities, and whether these abilities moderate the impact of bullying experiences on body image shame and eating psychopathology. We tested this model in a nonclinical sample of 609 adolescent girls aged 12–18 years. The examined model accounted for 22?% of body image shame variance and 51?% of eating psychopathology variance. Memories of warmth and safeness were significantly associated with self-reassurance, and negatively linked to body image shame and eating psychopathology. Self-reassurance significantly moderated the association between bullying experiences and both body image shame and eating psychopathology. The present findings suggest the relevance of assessing the quality of interpersonal experiences reported by adolescents and their potential association with self-reassuring abilities. Moreover, these results suggest that the ability to reassure and soothe the self may have a buffering effect against the negative impact of bullying experiences on adolescents’ body image and eating behaviors.     

Territorial gain dynamics regulates success in attacking sub-phases of team sports

Background and objective

Field invasion games, such as rugby union, can be conceptualised as dynamic social systems in which the agents continuously interact to contest ball possession and territorial gain. Accordingly, this study aimed to identify the collective system dynamics of rugby union phases-of-play near the try line by investigating whether ball displacement trajectory on the playing field provides insights on successful team performance.

Methods

Five rugby union matches were videotaped involving teams at a national league performance level. From these matches, 22 second phases-of-play were selected and digitized for analysis. The variable “distance gained” was investigated as a potential coordination variable describing functional coordination between players and teams. This variable concerned the distance between ball initial position and ball current position over time and was used to define the degree of territory gained by an attacking team.

Results

Analysis of distance gained dynamics in attacking sub-phases demonstrated the intermittent character of rugby union performers displacement trajectories on the playing field. Amplitude of ball movements was revealed as a distinguishing feature related to attacking effectiveness. Successful attacking phases displayed lower distances of positional retreat, with the maximum retreat distance achieved sooner in successful compared to unsuccessful phases-of-play. Autocorrelation and ApEn analyses suggested low system variability within time series data concerning both performance outcomes. However, evidence of less regularity and more complexity was found in unsuccessful phases-of-play.

Conclusion

Results suggested that distance gained dynamics manifests a characteristic collective behaviour pattern that captures the macroscopic functional order of multi-player attack–defence systems in team sports like rugby union.     

Maternal concepts and expectations regarding a preterm infant

The objective of the present study was: (a) to identify the concerns, verbally expressed, of 50 mothers regarding their preterm infants (PT) and then compare their verbal expression with those of 25 mothers of full-term infants (FT); and (b) to correlate the mothers' verbal expressions with maternal and infant variables. The following instruments were used to compose and characterize the sample: Structure Clinical Interview for DSM III-R Non-Patient (SCID/NP), State-Trait Anxiety Inventory (STAI), Beck Depression Inventory (BDI), and medical charts. Results showed that there was no difference between groups in term of mothers' expectations and conceptualizations; both groups exhibited predominantly positive expectations and concepts. In comparison with FT mothers, PT mothers verbally expressed more feelings and reactions predominantly negative or conflicting in relation to infant birth. Higher levels of maternal anxiety and depression in the PT Group were correlated with more verbal expressions about negative or conflicting emotions. In addition, lower birth weight, higher neonatal risk and longer length of stay in intensive care nursery of the infants were related with more negative or conflicting concepts by the mothers.     

Reinforcement learning, conditioning, and the brain: Successes and challenges

The field of reinforcement learning has greatly influenced the neuroscientific study of conditioning. This article provides an introduction to reinforcement learning followed by an examination of the successes and challenges using reinforcement learning to understand the neural bases of conditioning. Successes reviewed include (1) the mapping of positive and negative prediction errors to the firing of dopamine neurons and neurons in the lateral habenula, respectively; (2) the mapping of model-based and model-free reinforcement learning to associative and sensorimotor cortico-basal ganglia-thalamo-cortical circuits, respectively; and (3) the mapping of actor and critic to the dorsal and ventral striatum, respectively. Challenges reviewed consist of several behavioral and neural findings that are at odds with standard reinforcement-learning models, including, among others, evidence for hyperbolic discounting and adaptive coding. The article suggests ways of reconciling reinforcement-learning models with many of the challenging findings, and highlights the need for further theoretical developments where necessary.

Spiritist Hospital Chaplaincy in Brazil: 5 Years of Documented Experience

Spiritist Hospital Chaplaincy in Brazil has been growing significantly in recent years, with the implementation of new services through the work of Spiritist Medical Associations (SMAs) in different regions of the country. This article describes the importance of historical interconnections from the advent of spiritism in the world and its introduction in Brazil to the emergence of Spiritist Hospital Chaplaincy in our country and presents the documented experience over 5 years of spiritist chaplain care, in the period from 2012 to 2016, guided by the SMA of Piracicaba at the Unimed Hospital of Piracicaba (São Paulo). We documented 41,914 visits to 13,983 inpatients and an analysis of these records allowed us to reflect on the importance of this service and confirm its expansion and acceptance by different contemporary religious beliefs.
