Daphnia females adjust sex allocation in response to current sex ratio and density
2018
Cyclical parthenogenesis presents an interesting challenge for the study of sex allocation, as individuals’ allocation decisions involve both the choice between sexual and asexual reproduction, and the choice between sons and daughters. Male production is therefore expected to depend on ecological and evolutionary drivers of overall investment in sex, and those influencing male reproductive value during sexual periods. We manipulated experimental populations, and made repeated observations of natural populations over their growing season, to disentangle effects of population density and the timing of sex from effects of adult sex ratio on sex allocation in cyclically parthenogenetic Daphnia…
Predicting adolescent adjustment and well-being: The interplay between socio-emotional and personal factors
2019
Social and emotional factors such as emotional competence and self-esteem are protective factors that promote adolescent mental health and well-being. In this paper, we will examine the combined contribution of these socio-emotional factors in addition to personal factors, in the prediction of psychological adjustment and subjective well-being in adolescence. The study included 840 adolescents aged between 12 and 16 years old (M = 13.37, SD = 1.16, 51.4% girls). We measured personal variables (sex, age, number of siblings), socio-emotional variables (emotional competence and self-esteem), psychological adjustment (emotional and behavioural problems) and subjective well-being (life satisfact…
The Protective Role of Prosocial Behaviors on Antisocial Behaviors: The Mediating Effects of Deviant Peer Affiliation
2014
Prosocial behaviors, actions intended to help others, may serve a protective function against association with deviant peers and subsequent delinquent and antisocial behaviors. The present study examined the relations among specific types of prosocial behaviors, deviant peer affiliation, and delinquent and aggressive behaviors. Six hundred and sixty-six adolescents (46% girls; M age = 15.33, SD = .47) from Valencia, Spain completed questionnaires of prosocial behaviors, affiliation with deviant peers, antisocial behaviors, and aggression. Results showed that antisocial behaviors were negatively related only to specific forms of prosocial behaviors. Further analyses showed that deviant peer …
Achievement strategies in peer groups and adolescents' school adjustment and norm-breaking behavior.
2006
The present study examined the extent to which the achievement strategies deployed by adolescents, and those used by their peers would predict adolescents' school adjustment, academic achievement and problem behavior. The participants were 287 14-15-year-old comprehensive school students (121 boys and 165 girls) from a middle-sized town in central Sweden. The results showed that not only the maladaptive strategies used by adolescents, but also those reported by their peers predicted adolescents' norm-breaking behavior, low school adjustment and low level of achievement: high levels of failure expectations and task-avoidance among adolescents' peers were positively associated with adolescent…
Insights Into Aspects Behind Internet-Related Disorders in Adolescents: The Interplay of Personality and Symptoms of Adjustment Disorders
2017
Abstract Purpose Problematic Internet use (PIU) that has recently been referred to as Internet-related disorder is a growing health concern. Yet, it is unclear why some adolescents are developing problematic use, whereas others sustain control. Based on previous research, we hypothesize that personality traits (low conscientiousness and high neuroticism) act as predispositions for PIU. We further hypothesize that PIU can be understood as a maladaptive reaction toward critical life events and that these maladaptive reactions are exacerbated by dysfunctional personality traits. Methods The study investigates the prevalence of distinct subtypes of PIU among a sample of adolescents (n = 1,489; …
Assessing Planning Ability Across the Adult Life Span: Population-Representative and Age-Adjusted Reliability Estimates for the Tower of London (TOL-…
2015
Planning ahead the consequences of future actions is a prototypical executive function. In clinical and experimental neuropsychology, disc-transfer tasks like the Tower of London (TOL) are commonly used for the assessment of planning ability. Previous psychometric evaluations have, however, yielded a poor reliability of measuring planning performance with the TOL. Based on theory-grounded task analyses and a systematic problem selection, the computerized TOL-Freiburg version (TOL-F) was developed to improve the task's psychometric properties for diagnostic applications. Here, we report reliability estimates for the TOL-F from two large samples collected in Mainz, Germany (n = 3,770; 40-80 y…
Perceived social support and mortality in older people.
2006
Objectives This study examines the effect of perceived social support on all-cause mortality at a 10-year follow-up as well as the plausible mediating factors in this association. Methods We measured perceived social support in 206 Finnish men and women aged 80 years old by using the Social Provision Scale, which consists of six dimensions: attachment, social integration, opportunity for nurturance, reassurance of worth, reliable alliance, and guidance. Results By using a theoretical framework that divided perceived social support into assistance-related and non-assistance-related support, we found that the risk of death was almost 2.5 times higher in women in the lowest tertile of non-assi…
Practice-Related Improvements in Postural Control During Rapid Arm Movement in Older Adults: A Preliminary Study
2012
International audience; Background. Postural control associated with self-paced movement is critical for balance in older adults. The present study aimed to investigate the effects of a virtual reality based program on the postural control associated with rapid arm movement in this population. Methods. From an upright standing position, participants performed rapid arm raising movements toward a target. Practice-related changes were assessed by pre- and posttest comparisons of hand kinematics and center of pressure displacement parameters measured in a training group (mean age: 71.50 +/- 2.67 years, n = 8) and a control group (mean age: 72.87 +/- 3.09 years, n = 8). Training group participa…
Hospital Contacts for Psychiatric Disorders in Parents of Children With Cancer in Denmark
2021
Abstract Background Having a child diagnosed with cancer is a devastating experience that may affect parents’ mental health. We aimed to assess the risk of hospital contacts for psychiatric disorders in parents of children with cancer. Methods We conducted a nationwide population-based cohort study using Danish registry data. Parents of children diagnosed with cancer between 1982 and 2014 (n = 6689 mothers, n = 5509 fathers) were matched with comparison parents of cancer-free children (n = 67 544 mothers, n = 55 756 fathers). We used Cox proportional hazards models to estimate the risk of hospital contacts for any psychiatric disorder and specific disorders. Cox models were also used to inv…
The role of emotion awareness and mood: somatic complaints and social adjustment in late childhood.
2014
Emotion awareness is a key concept related to different child adjustment outcomes. This relationship, influenced by mood, has been found in the preadolescent and adolescent population for somatic complaints. However, little is known in the case of younger children and when other adjustment outcomes are included. The objective of this work is to analyze the contribution of emotion awareness and mood upon different adjustment outcomes (somatic complaints, maladjustment, and peer sociometric status), in children aged 8-12 years old. Self-reported questionnaires and peer-nomination scales were administered to 1423 children (mean age = 9.8 years old). Results support the influence of emotion awa…
