The effect of a non-steroidal anti-inflammatory drug on two important predictors for accidental falls: Postural balance and manual reaction time. A randomized, controlled pilot study

Accidental falls in older individuals are a major health and research topic. Increased reaction time and impaired postural balance have been determined as reliable predictors for those at risk of falling and are important functions of the central nervous system (CNS). An essential risk factor for falls is medication exposure. Amongst the medications related to accidental falls are the non-steroidal anti-inflammatory drugs (NSAIDs). About 1-10% of all users experience CNS side effects. These side effects, such as dizziness, headaches, drowsiness, mood alteration, and confusion, seem to be more common during treatment with indomethacin. Hence, it is possible that maintenance of (static) postural balance and swift reactions to stimuli are affected by exposure to NSAIDs, indomethacin in particular, consequently putting older individuals at a greater risk for accidental falls. The present study investigated the effect of a high indomethacin dose in healthy middle-aged individuals on two important predictors of falls: postural balance and reaction time. Twenty-two healthy middle-aged individuals (59.5 ± 4.7 years) participated in this double-blind, placebo-controlled, randomized crossover trial. Three measurements were conducted with a week interval each. A measurement consisted of postural balance as a single task and while concurrently performing a secondary cognitive task and reaction time tasks. For the first measurement indomethacin 75 mg (slow-release) or a visually identical placebo was randomly assigned. In total, five capsules were taken orally in the 2.5 days preceding assessment. The second measurement was without intervention, for the final one the first placebo group got indomethacin and vice versa. Repeated measures GLM revealed no significant differences between indomethacin, placebo, and baseline in any of the balance tasks. No differences in postural balance were found between the single and dual task conditions, or on the performance of the dual task itself. Similarly, no differences were found on the manual reaction time tasks. The present study showed that a high indomethacin dose does not negatively affect postural balance and manual reaction time in this healthy middle-aged population. Although the relatively small and young sample limits the direct ability to generalize the results to a population at risk of falling, the results indicate that indomethacin alone is not likely to increase fall risk, as far as this risk is related to abovementioned important functions of the CNS, and not affected by comorbidities.     

The effects of mothers' past infant-holding preferences on their adult children's face processing lateralisation

Face processing development is negatively affected when infants have not been exposed to faces for some time because of congenital cataract blocking all vision (Le Grand, Mondloch, Maurer, & Brent, 2001). It is not clear, however, whether more subtle differences in face exposure may also have an influence. The present study looked at the effect of the mother's preferred side of holding an infant, on her adult child's face processing lateralisation. Adults with a mother who had a left-arm preference for holding infants were compared with adults with a mother who had a right-arm holding preference. All participants were right-handed and had been exclusively bottle-fed during infancy. The participants were presented with two chimeric faces tests, one involving emotion and the other one gender. The left-arm held individuals showed a normal left-bias on the chimeric face tests, whereas the right-arm held individuals a significantly decreased left-bias. The results might suggest that reduced exposure to high quality emotional information on faces in infancy results in diminished right-hemisphere lateralisation for face processing.     

Changing brains, changing perspectives: the neurocognitive development of reciprocity

Adolescence is characterized by the emergence of advanced forms of social perspective taking and significant changes in social behavior. Yet little is known about how changes in social cognition are related to changes in brain function during adolescence. In this study, we investigated the neural correlates of social behavior during three phases of adolescence, carrying out functional magnetic resonance imaging of participants' brains while they were Player 2 in the Trust Game. We found that with age, adolescents were increasingly sensitive to the perspective of the other player, as indicated by their reciprocal behavior. These advanced forms of social perspective-taking behavior were associated with increased involvement of the left temporo-parietal junction and the right dorsolateral prefrontal cortex. In contrast, young adolescents showed more activity in the anterior medial prefrontal cortex, a region previously associated with self-oriented processing and mentalizing. These findings suggest that the asynchronous development of these neural systems may underlie the shift from thinking about self to thinking about the other.     

Facing a Disruptive Face: Embodiment in the Everyday Experiences of “Disfigured” Individuals

In recent years, facial difference is increasingly on the public and academic agenda. This is evidenced by the growing public presence of individuals with an atypical face, and the simultaneous emergence of research investigating the issues associated with facial variance. The scholarship on facial difference approaches this topic either through a medical and rehabilitation perspective, or a psycho-social one. However, having a different face also encompasses an embodied dimension. In this paper, we explore this embodied dimension by interpreting the stories of individuals with facial limb absence against the background of phenomenological theories of the body, illness and disability. Our findings suggest that the atypical face disrupts these individuals’ engagement with everyday projects when it gives rise to disruptive perceptions, sensations, and observations. The face then ceases to be the absent background to perception, and becomes foregrounded in awareness. The disruptions evoked by facial difference call for adjustments: as they come to terms with their altered face, the participants in our study gradually develop various new bodily habits that re-establish their face’s absence, or relate to its disruptive presence. It is through these emergent habits that facial difference comes to be embodied. By analyzing the everyday experiences of individuals with facial limb absence, this article provides a much-needed exploration of the embodied aspects of facial difference. It also exemplifies how a phenomenological account of illness and disability can do justice both to the impairments and appearance issues associated with atypical embodiment.     

A routine perspective on implementing reflective career conversations in education

ABSTRACT

Reflective career conversations are a necessary instrument in the career guidance of students in vocational education. These conversations help students to learn from their (work) experiences and gain a better understanding of their motives on the labour market. Research shows that in a society in which change seems to become the only constant factor, knowing one’s own motives in work is important. However, the introduction and implementation of reflective career conversations in Dutch vocational education is problematic. In this article, we introduce the concept of ‘routines’ to better understand the nature of these problems. The concept ‘routine’ allows us to understand in much more detail what is required to induce the necessary behavioural changes that are required from teachers, students and management. Recognition of the complexity of this process and the willingness to invest are necessary prerequisites to prevent reflective career conversations from becoming the next ‘trick’ or ‘trendy innovation’.     

Compulsive Internet Use Among Adolescents: Bidirectional Parent–Child Relationships

Although parents experience growing concerns about their children’s excessive internet use, little is known about the role parents can play to prevent their children from developing Compulsive Internet Use (CIU). The present study addresses associations between internet-specific parenting practices and CIU among adolescents, as well as the bidirectionality of these associations. Two studies were conducted: a cross-sectional study using a representative sample of 4,483 Dutch students and a longitudinal study using a self-selected sample of 510 Dutch adolescents. Results suggest that qualitatively good communication regarding internet use is a promising tool for parents to prevent their teenage children from developing CIU. Besides, parental reactions to excessive internet use and parental rules regarding the content of internet use may help prevent CIU. Strict rules about time of internet use, however, may promote compulsive tendencies. Finally, one opposite link was found whereby CIU predicted a decrease in frequency of parental communication regarding internet use.     

Capturing autonomy,competence, and relatedness at work: Construction and initial validation of the Work‐related Basic Need Satisfaction scale

The satisfaction of the basic psychological needs for autonomy, competence, and relatedness, as defined in Self‐Determination Theory, has been identified as an important predictor of individuals' optimal functioning in various life domains. The study of work‐related need satisfaction seems, however, hampered by the lack of a validated measure. To assist future research, the present study aimed to develop and validate a Work‐related Basic Need Satisfaction scale (W‐BNS). Using four Dutch‐speaking samples, evidence was found for the three‐factor structure of the scale, the discriminant validity, and the reliability of the three need satisfaction subscales as well as their criterion‐related and predictive validity. The W‐BNS may therefore be considered as a promising tool for future research and practice.     

Designing for Trust: A Case of Value-Sensitive Design

In this paper, we consider the meaning, roles, and uses of trust in the economic and public domain, focusing on the task of designing systems for trust in information technology. We analyze this task by means of a survey of what trust means in the economic and public domain, using the model proposed by Lewicki and Bunker, and using the emerging paradigm of value-sensitive design. We explore the difficulties developers face when designing information technology for trust and show how our analysis in conjunction with existing engineering design methods provides means to address these difficulties. Our main case concerns a concrete problem in the economic domain, namely the transfer of control from customs agencies to companies. Control of individual items is increasingly untenable and is replaced by control on the level of companies aimed at determining whether companies can be trusted to be in control of their business and to be in compliance with applicable regulations. This transfer sets the task for companies to establish this trust by means of information technology systems. We argue that this trust can be achieved by taking into account philosophical analyses of trust and by including both parties in the trust relationship as clients for whom the information technology systems are to be designed.     

The influence of interdependent self-construal on procedural fairness effects

Various theories have been shown to account for the effects of procedural fairness on people’s attitudes and behaviors. We propose that a logical next step for organizational justice researchers is to delineate not whether, but rather when certain explanations are likely to account for people’s reactions to procedural fairness information. Accordingly, the present research tested the hypothesis that social psychological explanations would be particularly applicable to people high in interdependent self-construal. As predicted, the results of three studies showed that interdependent self-construal (ISC) moderated the relationship between procedural fairness and a variety of dependent variables (cooperation, positive affect, and desire for future interaction with the other party). In different types of interpersonal encounters (social dilemmas, reward allocations, and negotiations), procedural fairness had more of an influence on participants’ reactions among those high rather than low in ISC. Theoretical implications are discussed.
