Developmental relations between ADHD symptoms and bullying perpetration and victimization in adolescence

It has previously been hypothesized that individuals with elevated attention deficit hyperactivity disorder (ADHD) symptoms are at greater risk of bullying perpetration and victimization. Using autoregressive latent trajectory models with structured residuals (ALT‐SR) and four waves (ages 11, 13, 15, and 17) of longitudinal data from the normative z‐proso study (n = 1526, 52% male), we evaluated the developmental relations between ADHD and bullying using both self‐ and teacher‐reported ADHD symptom data. Analyses suggested that ADHD symptoms primarily increase the risk of bullying perpetration, with a within‐person effect of ADHD symptoms on bullying perpetration symptoms identified across ages 13–15 (β = .13) and ages 15–17 (β = .19) based on self‐reported ADHD symptoms and a similar effect identified across ages 11–13 (β = .24) and 13–15 (β = .29) based on teacher‐reported inattention symptoms. There were also some indications of reciprocal effects and effects involving victimization that merit further exploration in future research. Results imply that the content of bullying intervention and prevention programs should take account of ADHD symptoms to ensure that those with elevated symptoms can benefit as much as their typically developing peers. This will involve addressing bullying perpetration that may reflect impulsive/reactive aggression and impaired social skills rather than instrumental aggression. Further, programs should go beyond classical curriculum/classroom‐based delivery to ensure that individuals with elevated ADHD symptoms can be successfully engaged.     

Family and food variables that influence life satisfaction of mother-father-adolescent triads in a South American country

This study explored the influence of each family member’s life satisfaction on the other family members’ life satisfaction in mother-father-adolescent triads. We also explored the influence of each family member’s satisfaction with food-related life and family life on their own life satisfaction (LS) as well as on the other family members’ LS in mother-father-adolescent triads. The influence of family eating habits, food-related parenting practices used by each parent and sociodemographic characteristics on each family member’s LS were also explored. A survey was applied to a sample of 300 two-parent families with one child between 10 and 17 years of age in Temuco, Chile. The questionnaire included the Satisfaction with Life Scale, Satisfaction with Food-related Life scale, Satisfaction with Family Life scale, Adapted Healthy Eating Index, Family Food Behavior Survey and Family Eating Habits Questionnaire. Frequency and sources of family meals as well as sociodemographic characteristics were also consulted. Three multivariate ordinal logit models were proposed, with the dependent variable LS in the three subsamples: mothers, fathers and adolescents. The three logit models were significant, but differed in the explanatory variables. Mothers’ LS was influenced by their children’s LS and vice versa. Mothers’ LS was positively influenced by both their own satisfaction with family life and the fathers’ satisfaction with family life and vice versa. Children’s LS was also positively influenced by their own satisfaction with food-related and family life. Both parents’ LS was influenced by eating habits, food-related parenting practices and sociodemographic characteristics, but in different ways. Therefore, different interventions should be implemented to improve each family member’s life satisfaction.

     

The assessment of individual “Aggressiveness” in pigeons by a variety of means

Pigeons attack or threaten animate and inanimate targets. The assessment of their aggressiveness was studied by exposing them in their home cages to three different stimuli: the experimenter's hand, a live pigeon, and a rear-projected conspecific image when the birds were exposed to intermittent access to food. A positive correlation between the hand test and live pigeon test was evident, but no relationship between either of these responses and the response to a pictorial image was observed. These results combined with other ethological observations cast doubts on the usefulness of schedule-induced responses to pictorial targets in the assessment of the individual aggressiveness in pigeons, but suggest that the hand test is an adequate and reliable procedure for such evaluations.

Effect of autonomy support and dialogic learning on school children’s physical activity and sport

This study applies an intervention based on autonomy support through dialogic learning to examine effects on motivation and the promotion of physical activity and sport involvement during schoolchildren’s leisure time. One hundred and two primary school students, aged 11–13 years, participated (M = 10.93, SD = 0.75). The sample was divided into two groups: an experimental group (49 students) and a control group (53 students). A quasi-experimental study was conducted in physical education classes over the course of 9 months. Assessments of autonomy support from teachers, family, and peers; basic psychological needs; self-determined motivation in physical education and during leisure time; planned behavior variables; physical activity intention; and estimated and actual physical exercise behavior time were included in the model. Following the intervention, the results revealed that greater autonomy support by the teacher, the family and peers, satisfaction of the basic psychological needs, self-determined motivation during physical education class and during free time, greater perceived control, favorable attitude and intention to engage in physical activity contributed to the explanation of student physical activity involvement. These results suggest that when students receive extensive social support from diverse social agents that essential precursors to physical activity are strengthened and contribute to increased motivation and actual physical activity involvement. Efforts to promote effective communications with students and other pedagogical efforts, such as providing dialogic learning opportunities, should be considered in order to strengthen physical activity motivation and involvement in students.     

Does Partisan Bias Modulate Neural Processing of Political Information? An Analysis of the Neural Correlates of Corruption and Positive Messages

Daily worldwide newspapers print articles exposing government corruption. Yet these messages do not lead to a loss of votes for the corrupt parties. Sympathizers’ partisan bias, which respectively minimizes and maximizes corruption and positive messages of their own parties respectively, is widely considered the main cause of the loss of effectiveness of political communications. Despite the well-established existence of such bias when processing political information, little is known as to its psychological origin. Through the use of neuroscience (fMRI), this study explores the underlying brain mechanisms of negative (corruption) and positive political messages related to a conservative and a socialist Spanish political party, as well as the differences between their sympathizers. The findings reveal that negative (vs. positive) political messages exert the greatest neuroimaging impact on the electorate, as shown in aversive, risk, and disappointment-related brain regions. Interestingly, we show that there exists a main partisan bias against opposite parties (and not a positive bias toward one’s own party) that stems from a higher risk, ambiguity, and disbelief provoked by both positive and negative information about rival parties. Furthermore, this bias was more pronounced among conservative supporters. The current findings provide valuable insights for political parties to improve their communication campaigns.

Distress in response to emotional and sexual infidelity: evidence of evolved gender differences in Spanish students

The authors studied gender differences in response to hypothetical infidelity in Spanish students. Using a forced-choice methodology, the authors asked a sample of 266 participants to indicate which kind of infidelity would be more distressing: emotional or sexual. Men were significantly more distressed by sexual infidelity than were women, and women were significantly more distressed by emotional infidelity than were men. Results supported the hypothesis that particular infidelity types, which resemble adaptive problems that human beings faced in the past, contribute to the psychology of jealousy. The results are consistent with previous cross-cultural research.     

Mental Attention, Consciousness, and the Progressive Emergence of Wisdom

I discuss the mental–attentional mechanisms of consciousness, meditation, and the emergence of wisdom. A developmental (neoPiagetian), dynamic flash-light model of mental attention is used. I model the initial stages of consciousness in infancy, showing that the growth of consciousness is influenced by the number of schemes that attention can coordinate. I discuss ordinary consciousness in adults and the stages/levels of adult development in consciousness. Wisdom is defined as an expectable but often missed outcome of adult development. To accelerate access to wisdom, two complementary paths are mentioned: a natural life-experience path and a meditation path. Maturational organismic factors and the role of mental attentional mechanisms in these two paths are discussed, and a constructivist neuropsychological model of what happens in the brain during meditation, and in higher consciousness, is sketched. Processes involved in higher stages of consciousness are then examined from this perspective.
