Comparison between two continuous performance tests for identifying ADHD: Traditional vs. virtual realityEjecución continua para la detección del TDAH: pruebas tradicionales frente a la realidad virtual

Background/Objective: Continuous Performance Tests (CPTs) have demonstrated validity when differentiating children with ADHD from healthy controls. However, these CPTs have limitations such as low ecological validity. New CPTs based on the use of Virtual Reality (VR) have appeared as supposedly improved methods for assessing ADHD. This study aims to compare the discriminant value of attentional variables produced by a VR CPT (Aula Nesplora) with that of variables from a traditional CPT (Test of Variables of Attention; TOVA) for identifying ADHD. Method: A total of 338 children aged between 6 and 16 years old (M = 10.84, SD = 3.01) participated in the study: 31.95% correspond to the inattentive presentation, 15.38% to the impulsive-hyperactive presentation, 22.78% to the combined presentation, and the remaining 29.88% correspond to children without ADHD. Results: Results indicated that Aula Nesplora predicts ADHD presentations better than TOVA. It also differentiates better between ADHD and non-ADHD students. Conclusions: These findings show the potential advantages of using virtual reality in ADHD assessment, as it facilitates the diagnosis of ADHD and the differentiation of its presentations in a realistic environment.     

Psychometric properties of the Shared Decision-Making Questionnaire (SDM-Q-9) in oncology practicePropiedades psicométricas del Questionnaire Shared Decision-Making (SDM-Q-9) en oncología

Background/Objective: This study sought to assess the psychometric properties of the 9-item Shared Decision-Making Questionnaire (SDM-Q-9) in patients with resected, non-metastatic cancer and eligible for adjuvant chemotherapy. Method: A total of 568 patients were recruited from a multi-institutional, prospective, transversal study. Patients answered the SDM-Q-9 after visiting their medical oncologist who, in turn, completed the SDM-Q–Physician version. Reliability, factorial structures [exploratory factor analysis (EFA), confirmatory factor analysis (CFA)], and convergent validity of the SDM-Q-9 scores were explored. Results: SDM-Q-9 showed a clear factorial structure, compatible with a strong and replicable general factor and a secondary group factor, in patients with resected, non-metastatic cancer. Total sum scores derived from the general factor showed good reliability in terms of omega coefficient: .90. The association between patient and physician perception of SDM was weak and failed to reach statistical significance. Males and patients over 60 years of age displayed the greatest satisfaction with SDM. Conclusions: SDM-Q-9 can aid in evaluating SDM from the cancer patients’ perspective. SDM-Q-9 is helpful in studies examining patient perspectives of SDM and as an indicator of the degree of quality and satisfaction with health care and patient-physician relationship.     

The influence of rule availability and item similarity on metacognitive monitoring during categorisation

In four experiments, we examined the sources of metacognitive judgments during the categorisation of new items after the learning of old items was completed. In the rule condition, the categorisation rule was explicitly given to the participants during learning, while in the no-rule condition participants relied on feedback to infer category membership. In the transfer phase, two types of novel items were used: good and bad transfer items. Transfer items also differed in the level of similarity to their training pairs. In the rule condition, all types of transfer items were classified with high accuracy and confidence. In the no-rule condition, a dissociation between accuracy and confidence was revealed. Good transfer items were classified more accurately than bad transfer items, whereas similar items were classified with higher confidence than dissimilar items. The obtained results suggest the utilisation of two potential cues for metacognitive judgments: declarative knowledge if the correct rule is explicitly available, and item similarity if it is difficult to infer the correct rule from feedback.     

Factor Structure and Internal Consistency of a Spanish Version of the Family Quality of Life (FaQoL)

This study examines the factor structure and internal consistency of the Spanish version of the Family Quality of Life scale (FaQoL). After translating and back-translating the instrument, we administered it to 324 families with a child with disabilities or developmental delays or who was at risk and who was enrolled in an early intervention (EI) program. Families were recruited from EI services in Spain, from 12 autonomous communities. Children’s average age was 38.6 months. Results showed the FaQoL scores had high internal consistency. Confirmatory factor analysis showed an adequate fit with the original factors, even slightly higher than the original four-factor solution. These results allow factors scores to be used reliably with Spanish families.     

Projective Geometry in Logical Space: Rethinking Tractarian Thoughts

Customary interpretations state that Tractarian thoughts are pictures, and, a fortiori, facts. I argue that important difficulties are unavoidable if we assume this standard view, and I propose a reading of the concept taking advantage of an analogy that Wittgenstein introduces, namely, the analogy between thoughts and projective geometry. I claim that thoughts should be understood neither as pictures nor as facts, but as acts of geometric projection in logical space. The interpretation I propose thus removes the root of the identified difficulties. Moreover, it allows important clarification concerning some central aspects of the Tractarian theory of representation, and it yields a unifying elucidation regarding Wittgenstein’s remarks on the solipsistic thesis.     

Do we need visual subjects?

It is widely accepted within contemporary philosophy of perception that the content of visual states cannot be characterized simply as a list of represented features. This is because such characterization leads to the so-called ‘Many Properties’ problem, that is, it does not allow us to explain how the visual system is able to distinguish between scenes containing different arrangements of the same features. The usual solution to the Many Properties problem is to characterize some basic elements of content as subjects, to which features are attributed by a predication-like relation. In this paper, I reconsider this solution and claim that the Many Properties problem can be solved without postulating such subjects. What is more, I argue that an alternative approach has stronger justification given the empirical data concerning human vision.     

Temperament and Behavioral Problems in Young Children: the Protective Role of Extraversion and Effortful Control

This study examines the relationships between temperament traits (negative affectivity, extraversion and effortful control) and children’s externalized and internalized behavioral problems. The sample was composed of 424 children from the ages of 3–6 years old (60% male). Use of a hierarchical regression analysis revealed direct and interactive effects. Specifically, reactive temperamental traits were found to predict behavioral problems in children: negative affect tended to increase externalizing problems, and extraversion tended to decrease internalizing problems. The regulative temperament trait (“effortful control”) negatively predicted both internalizing and externalizing problems. To explore moderating effects, post‐hoc analyses were conducted using the Johnson–Neyman technique with Hayes’s PROCESS. Our analyses revealed that high levels of negative affect (characterized in our study by a higher load of anger or frustration than of fear or sadness) makes a significant and strong contribution to internalizing problems when effortful control reaches its highest levels. Thus, our results endure the protective role of extraversion as preventing the emergence of internalizing problems, and the protective role of effortful control as preventing the emergence of both, internalizing and externalizing, problems. The results also alert to the potential risk of a combination between high levels of effortful control and high levels of negative affect. Overall findings are discussed with regard to previous and future research.     

A Unique Historical Case to Understand the Present Sustainable Development

Every innovation seeks to become a profitable business, with this considered to be the engine for economic prosperity. When an innovation is revolutionary, its long-term consequences can be revolutionary too. The Haber-Bosh process for ammonia synthesis is arguably the twentieth century’s most significant innovation, and its importance to global food production and its impact on the environment are not expected to diminish over the coming decades. The historical case of the ammonia synthesis process invented by Fritz Haber and the ensuing innovation provides an incomparable opportunity to illustrate the interactions across contemporary needs, prominent scientists, political concerns, moral dilemmas, ethics, governance and environmental implications at a time when the concept of sustainability was still in its infancy. Despite its high economic and environmental costs, no cleaner or more efficient sustainable alternative has so far been found, and so replacing this “old” innovation that still “feeds” a large part of the world’s population does not appear to be on the cards in the near future.     

Supporting families of transgender children/youth: Parents speak on their experiences,identity, and views

ABSTRACT

Background: Transgender children/youth demonstrate the best possibility for resilience and positive mental health when they are part of an affirming and supportive family. To optimize families in supporting transgender children/youth, parents/caregivers need to be supported. Transgender children/youth and their families regularly navigate a myriad of challenges through society.

Aims: Within the extant literature on transgender children and youth, relatively little attention is focused on the experiences of parents/caregivers and how their close family relationships are affected. The present qualitative study addresses this gap in knowledge through its exploration of the experiences, identities, and views of parents/caregivers of transgender children/youth.

Method: The study is longitudinal and this article represents the first wave. Fourteen parents of 12 transgender children/youth, aged 6–17, participated in in-depth semistructured interviews. Participants were recruited via social media and at an on-site conference for transgender youth and their families. All children/youth had socially transitioned. Those who were eligible for puberty suppression and/or hormone therapy were receiving those. The interviews were inductively coded for themes by two coders using the constant comparative method.

Results: Participants' reports on their experiences yielded three themes: (1) transgender issues as the family's focus; (2) proactivity, child-focused: preemptive actions to prevent adverse consequences; and (3) self-care. These themes included subthemes on effective coping strategies to mitigate struggles. Three themes related to participants' identity and views emerged: (1) identity reformation, (2) self-evaluation, and (3) views of future. These themes included subthemes that reflected how participants viewed themselves, their child, and the future.

Discussion: A transgender identity in one family member affects all household members. Parents/guardians may experience guilt and self-doubt over decisions. Factors that may improve outcomes with extended family and schools include families' preemptive dissemination of information on transgender identities and explicating expectations of respect and nonintrusion. Ingrained traditions may force life-altering decisions.
