Into the Unknown: Examining Neural Representations of Parent–Adolescent Interactions

The parent–adolescent relationship is important for adolescents’ emotion regulation (ER), yet little is known regarding the neural patterns of dyadic ER that occur during parent–adolescent interactions. A novel measure that can be used to examine such patterns is cross-brain connectivity (CBC)—concurrent and time-lagged connectivity between two individuals’ brain regions. This study sought to provide evidence of CBC and explore associations between CBC, parenting, and adolescent internalizing symptoms. Thirty-five adolescents (mean age = 15 years, 69% female, 72% Non-Hispanic White, 17% Black, 11% Hispanic or Latino) and one biological parent (94% female) completed an fMRI hyperscanning conflict discussion task. Results revealed CBC between emotion-related brain regions. Exploratory analyses indicated CBC is associated with parenting and adolescent depressive symptoms.

Equipment set-up among Olympic sprint and slalom kayak paddlers

The anthropometry and equipment set-up for sprint (31 male; 11 female) and slalom (12 male; 12 female) kayak paddlers who competed at the 2000 Olympic Games in Sydney were measured in the 15 day period before competition. This paper provides normative data for equipment set-up in these sports, as well as information about differences in rigging and paddle dimensions between sprint and slalom kayak paddlers. These differences were consistent for both male and female athletes, with sprint paddlers seated higher and using longer paddles with longer, though narrower, blades (p < 0.0001). Among male sprint paddlers, only minor differences in equipment set-up were found between competitors ranked in the top 10 places compared to the rest of the field. Considering all male paddlers initially, then sprint paddlers alone, significant (p < 0.01) regression equations were developed for the prediction of foot bar distance (r2 = 0.482 and 0.589 respectively) and hand grip distance (r2 = 0.400 and 0.541 respectively). The process of fine tuning equipment set-up often requires hours of practice with subjective feedback from the athlete. The normative data presented in this paper should assist coaches with this process as their athletes evolve toward their individual optimum set-up.     

Key non-controversial concepts of population education

The important components of population education should focus on sexuality rather than sex education; content for inclusion depends upon whether the goal is population awareness or critical awareness. Population awareness is the better understanding of the nature, causes, and consequences of population changes experienced by a community, country, region. Critical awareness is the intent and ability to change the sociocultural or educational characteristics that influence fertility, mortality, and migration. 6 basic concepts with universal applicability are discussed, because if not handled properly, the topic become controversial. The concepts are linked to developing thinking or reasoning ability. The concepts are as follows: 1) respect for others, particularly those of the opposite sex; 2) development of self-esteem for both boys and girls; 3) the knowledge that planning is possible and desirable; 4) postponement of first pregnancy; 5) acceptance of responsibility for the consequences of behavior; and 6) the ability to recognize and withstand social pressure. When children learn respect for others, there is little likelihood that others will be harmed. Respect for girls and women is particularly important, and harmful stereotyping and their effects should be pointed out. The key is to develop healthy attitudes and values toward people, not just an intellectualization of gender issues. Self-esteem is used here to mean self-worth in the present and the future. Children can be helped to develop confidence, perseverance, and optimism. Children need to understand that carefully thought out decisions should precede a birth; fatalism and destiny is a choice. Postponing the first pregnancy can lead to economic, emotional, and physical benefits. Risk to the health of the mother and baby occurs during the teen years. The best time for pregnancy is between the ages of 20 and 30 years. A pregnancy in the teen years may have longterm consequences such as more pregnancy and delivery complications or infertility. Social pressure may force behavior that does not conform to one's own convictions or be applicable to best options for the individual.     

The experience of arousal: a new basis for studying arousal effects in sport

Sports psychologists have for some time put forward the inverted-U-hypothesis as a useful working model of the relationship between arousal and performance. Although some emphasis in the sports psychology literature has been placed on the limitations of the hypothesis, generally the notion of an optimal level of arousal has been well received. A few authors have been less tolerant of the arguments put forward in the inverted-U-hypothesis and the restrictions of its theoretical stance. Sports psychologists have been slow to suggest or adopt diverse theoretical perspectives and consequently little real progress has been made. The danger is that this approach has become widely accepted almost without question. This review paper attempts to sum up the current position and, based on recent work, recommend alternative interpretations of arousal effects in sport.
