Imaginary Companions in Childhood: What Can Prospective Longitudinal Research Tell Us About Their Fate by Adolescence?

Do adolescents remember imaginary companions (ICs) from early childhood? Researchers interviewed 46 adolescent participants in a prospective longitudinal study about their ICs from early childhood (age 5½). The existence of one or more ICs was documented in early childhood for 48% of children (G. Trionfi & E. Reese, 2009). At age 16, most adolescents had forgotten their early childhood ICs: Only 5 of the 23 participants who had early childhood ICs recalled those ICs later. Eight participants who had forgotten their early childhood ICs recalled a later IC, and four participants who did not have an IC at age 5 ½ reported one by age 16. Ten of the 23 participants who had early childhood ICs claimed never to have had an IC. Girls were more likely to recall their early childhood ICs. Retrospective reports of ICs in adolescence or later life may be unreliable for investigating differences between those with and without imaginary companions. Those with ICs may not be a homogenous group, with some creating ICs throughout childhood and some desisting from this behavior in early childhood. Findings indicate that both the remembering and forgetting of ICs has potential to illuminate cognitive and creative processes surrounding both memory and imagination.     

Ethics in Transnational Forensic DNA Data Exchange in the EU: Constructing Boundaries and Managing Controversies

Under EU Law, Member States are compelled to engage in reciprocal automated forensic DNA profile exchange for stepping up on cross-border cooperation, particularly in combating terrorism and cross-border crime. The ethical implications of this transnational DNA data exchange are paramount. Exploring what the concept of ethics means to forensic practitioners actively involved in transnational DNA data exchange allows discussing how ethics can be addressed as embedded in the sociality of science and in the way scientific work is legitimated. The narratives of forensic practitioners juxtapose the construction of fluid ethical boundary work between science and non-science with the dynamic management of controversies, both of which are seen as ways to lend legitimacy and objectivity to scientific work.

Ethical boundary work involves diverse fluid forms: as a boundary between science/ethics, science/criminal justice system, and good and bad science. The management of controversies occurs in three interrelated ways. First, through a continuous process of reconstructing delegations of responsibility in dealing with uncertainty surrounding the reliability of DNA evidence. Second, threats to the protection of data are portrayed as being resolved by black-boxing privacy. Finally, controversies related to social accountability and transparency are negotiated through the lens of opening science to the public.     

Quality of Life of Children and Adolescents with Short Stature: The Twofold Contribution of Physical Growth and Adaptive Height-Related Cognitive Beliefs

This study aimed to examine the health-related quality of life (HrQoL), coping, height-related beliefs, and social support of children/adolescents with short stature, the sociodemographic, clinical, and psychosocial variables associated with HrQoL, and the moderating role of sociodemographic and clinical variables on the associations between psychosocial variables and HrQoL. 114 Portuguese children/adolescents with short stature, aged 8–18 years old, completed the Quality of Life in Short Stature Youth questionnaire and the Satisfaction with Social Support Scale. Regression analyses explained 54% of the variance of HrQoL, with significant main effects of current height deviation and height-related beliefs, and a significant interaction effect between beliefs and diagnosis. Results suggest that a multidisciplinary therapeutic approach, not only focused on hormone treatment to boost physical growth, but also including psychosocial interventions focused on the modification of height-related beliefs, may contribute to improve the HrQoL of pediatric patients with short stature.

     

Longitudinal genetic analysis of anxiety sensitivity

Anxiety sensitivity is associated with both anxiety and depression and has been shown to be heritable. Little, however, is known about the role of genetic influence on continuity and change of symptoms over time. The authors' aim was to examine the stability of anxiety sensitivity during adolescence. By using a genetically sensitive design, the authors were also able to investigate the extent to which genetic and environmental factors influence anxiety sensitivity over time. Self-reports of anxiety sensitivity were obtained for over 1,300 twin and sibling pairs at 3 time points. Data were analyzed using multivariate genetic models. Anxiety sensitivity was moderately heritable at all time points with substantial nonshared environmental contributions. Time 1 genetic factors accounted for continuity of symptoms at Times 2 and 3. New genetic factors at Time 2 also influenced Time 3 symptoms. New nonshared environmental influences emerged at each time point. Analysis of a latent factor of trait anxiety sensitivity revealed some stable nonshared environmental influences. Genetic effects were generally stable over time, with new genetic influences emerging in late adolescence. Environmental influences on anxiety sensitivity were, on the whole, more time specific; however, some stable environmental influences were also found.     

A meta‐analysis of the effects of speakers' accents on interpersonal evaluations

This paper reports a meta‐analysis of the empirical literature on the effects of speakers' accents on interpersonal evaluations. Our review of the published literature uncovered 20 studies that have compared the effects of standard accents (i.e., the accepted accent of the majority population) versus non‐standard accents (i.e., accents that are considered foreign or spoken by minorities) on evaluations about the speakers. These 20 studies yielded 116 independent effect sizes on an array of characteristics that were selected by the original researchers. We classified each of the characteristics as belonging to one of three domains that have been traditionally discussed in this area, namely status (e.g., intelligence, social class), solidarity (trustworthiness, in‐group–out‐group member), and dynamism (level of activity and liveliness). The effect was particularly strong when American Network accented speakers were compared with non–standard‐accented speakers. These results underscore prior research showing that speakers' accents have powerful effects on how others perceive them. These and other results are discussed in the context of the literature along with implications for future research in this area. Copyright © 2011 John Wiley & Sons, Ltd.     

Don't mind meat? The denial of mind to animals used for human consumption

Many people like eating meat, but most are reluctant to harm things that have minds. The current three studies show that this dissonance motivates people to deny minds to animals. Study 1 demonstrates that animals considered appropriate for human consumption are ascribed diminished mental capacities. Study 2 shows that meat eaters are motivated to deny minds to food animals when they are reminded of the link between meat and animal suffering. Finally, Study 3 provides direct support for our dissonance hypothesis, showing that expectations regarding the immediate consumption of meat increase mind denial. Moreover, this mind denial in turn reduces negative affect associated with dissonance. The findings highlight the role of dissonance reduction in facilitating the practice of meat eating and protecting cultural commitments.     

To not make definite what is indefinite: A phenomenological analysis of perception and its epistemological consequences in human science research

Abstract

This paper explores the basics of human science, namely within the understanding of perception, which in fact is about how we as humans are in relationship to the world. There are several philosophical and psychological traditions trying to explain the nature of perception, the perceived, and the role of the perceiver. An idea that we argue against is that perception is about a changing subject perceiving a constant world, which means that there is a sharp dividing line between subject and object. Instead we argue that subject and object make up a dynamic relationship.     

Neurological subtle signs and cognitive development: A study in late childhood and adolescence

Introduction and Aim: Neurological subtle signs (NSS) are often observed during the neurological examination of children and tend to disappear with age. Their persistence into late adolescence or young adulthood has been related to psychiatric and neurocognitive disorders. To provide a better understanding of their functional basis, a longitudinal correlational study with neurocognitive measurements was performed.

Method: We conducted multiple regression and correlation analyses of NSS with demographic and cognitive measures on a subset of 341 healthy children (56% males), taking part in a longitudinal dental study. Participants, whose ages ranged between 11–15 years, at first evaluation, undertook yearly, during 5 years, a 6-item NSS exam (producing a total score ranging between 0–18) and a comprehensive battery of neurocognitive tests. Effects of age, gender, IQ, and 7 neurocognitive factors on NSS were analyzed.

Results: Over the years, NSS scores correlated consistently with selective attention (Stroop test), motor speed (finger tapping), and visuomotor speed (pegboard speed).

Discussion: These results suggest that the disappearance of NSS in late childhood and adolescence occurs primarily in parallel with the development of motor and visuomotor functions and secondarily in relation to higher order functions such as selective attention (Stroop) and executive control (B-A Trails difference).     

Adopted children's language difficulties and their relation to symptoms of reactive attachment disorder: FinAdo study

This study investigated the potential association between symptoms of reactive attachment disorder and language difficulties among internationally adopted children in Finland (the FinAdo study). The language difficulties were assessed using a standardised Five to Fifteen (FTF) parental questionnaire and the symptoms of reactive attachment disorder using a FinAdo questionnaire. The study sample consisted of 689 6–15 year old children (49.2% boys, response rate 48%). Twenty-nine percent of the children were reported to have language difficulties and 8% severe language difficulties (10% and 2%, respectively, in the general population). A child's symptoms of reactive attachment disorder were associated with language difficulties and severe language difficulties, OR 2.15, 95% CI [1.39, 3.31] and OR 4.33, 95% CI [1.57, 11.98], respectively, the associations being robust to adjustments for background factors.     

Attention control: Relationships between self-report and behavioural measures,and symptoms of anxiety and depression

Previous research has demonstrated differences in processing between fear-relevant stimuli, such as snakes and spiders, and non-fear-relevant stimuli. The current research examined whether non-fear-relevant animal stimuli, such as dogs, birds and fish, were processed like fear-relevant stimuli following aversive learning. Pictures of a priori fear-relevant animals, snakes and spiders, were evaluated as negative in affective priming and ratings and were preferentially attended to in a visual search task. Pictures of dogs, birds and fish that had been trained as CS+ in an aversive conditioning design were evaluated more negatively and facilitated dot probe detection relative to CS? pictures. The current studies demonstrated that stimuli viewed as positive prior to aversive learning were negative and were preferentially attended to after a brief learning episode. We propose that aversive learning may provide a mechanism for the acquisition of stimulus fear relevance.
