Children's understanding of embarrassment: Integrating mental time travel and mental state information

The current study investigated 4‐ to 8‐year‐olds’ (N = 81) understanding of embarrassment and their ability to integrate temporal and mental state information to predict and explain emotions. Participants heard stories describing characters commit trivial social transgressions, and then the next day, characters found themselves in the same situation that led to the previous transgression. For some story endings, participants were asked to predict and explain how the character felt, and for others, participants were told the character started to feel embarrassed and they were asked to explain why. Participants’ responses were coded and analysed using nonparametric statistical tests. Kruskal–Wallis analyses revealed significant developments occur between 6 and 8 years in children's understanding of embarrassment and their ability to explain individual's emotion as caused by anticipating the reoccurrence of a previous embarrassing event. Younger children demonstrated a basic knowledge of embarrassment but failed to demonstrate more advanced understanding of the emotion. Findings from the current study indicate children reach a more mature understanding of embarrassment and the implications of committing social transgressions between 7 and 8 years. Finally, the current study contributes to the literature on children's ability to infer mental states and temporally connect experiences.     

Children's recognition of emotions from vocal cues

Emotional cues contain important information about the intentions and feelings of others. Despite a wealth of research into children's understanding of facial signals of emotions, little research has investigated the developmental trajectory of interpreting affective cues in the voice. In this study, 48 children ranging between 5 and 10 years were tested using forced‐choice tasks with non‐verbal vocalizations and emotionally inflected speech expressing different positive, neutral and negative states. Children as young as 5 years were proficient in interpreting a range of emotional cues from vocal signals. Consistent with previous work, performance was found to improve with age. Furthermore, the two tasks, examining recognition of non‐verbal vocalizations and emotionally inflected speech, respectively, were sensitive to individual differences, with high correspondence of performance across the tasks. From this demonstration of children's ability to recognize emotions from vocal stimuli, we also conclude that this auditory emotion recognition task is suitable for a wide age range of children, providing a novel, empirical way to investigate children's affect recognition skills.     

Infants’ sense of approximate numerosity: Heritability and link to other concurrent traits

The ability to perceive approximate numerosity is present in many animal species, and emerges early in human infants. Later in life, it is moderately heritable and associated with mathematical abilities, but the etiology of the Approximate Number System (ANS) and its degree of independence from other cognitive abilities in infancy is unknown. Here, we assessed the phenotypic specificity as well as the influence of genetic and environmental factors on the ANS in a sample of 5-month-old twins (N = 514). We found a small-to-moderate but statistically significant effect of genetic factors on ANS acuity (heritability = 0.18, 95% CI: 0.02, 0.33), but only when differences in numerosity were relatively large (1:4 ratio). Non-verbal ability assessed with the Mullen Scales of Early Learning (MSEL) was found to be heritable (0.47; 95% CI: 0.34, 0.57) and the phenotypic association between ANS acuity and non-verbal ability performance was close to zero. Similarly, we found no association between ANS acuity and general attention during the task. An unexpected weak but statistically significant negative association between ANS acuity and scores on the receptive language scale of the MSEL was found. These results suggest that early ANS function may be largely independent from other aspects of non-verbal development. Further, variability in ANS in infancy seems to, to some extent, reflect genotypic differences in the population.

Highlights

• Assessing 514 infant twins with eye tracking, we found that infants' sense of approximate numerosity is heritable and not positively associated with concurrent attentional, cognitive or motor abilities.
• These results have implications for our understanding of development of mathematical ability and the link between cognitive abilities early in postnatal life.

     

Organizing the voice questionnaire for transgender persons

Abstract

Background: The validated Transsexual Voice Questionnaire Male to Female (TVQ^MtF) and the adapted TVQ Female to Male (FtM) (TVQ^FtM) are both 30-item-long questionnaires used to evaluate self-perception of voice in transgender persons. They are part of a series of questionnaires completed by transgender persons during follow-up of cross-sex hormone therapy (CSHT).

Aim: The aim of this study was to examine if these questionnaires can be organized.

Methods: The TVQ^MtF or the TVQ^FtM was filled out at the start of CSHT, by 145 trans women and 83 trans men. Data were analyzed by factor analyses on both the questionnaires.

Results: The factor analyses resulted in a three-factor solution for both the TVQ^MtF and the TVQ^FtM. The three factors were labeled as anxiety and avoidance, vocal identity, and vocal function.

Conclusion: Both the questionnaires can be organized into three factors. This could contribute to making shorter versions of the questionnaires. Shorter versions would be useful to hormone prescribing physicians to track down more quickly voice problems in trans people undergoing virilizing or feminizing hormone treatment.     

Simple devices for restricting the visual fields of birds

The construction and use of several simple occluders designed for long-term use is described. They permit limiting vision either to one eye or to the frontal or lateral visual fields and permit rapid interchange among these conditions.     

Doctors as patients: How psychological therapists experience the opposing ideologies

Research suggests that doctors experience higher levels of stress and mental health problems than the general population. Doctors frequently experience difficulty seeking help, and also challenges during psychological treatment, due to role reversal and competing ideologies.

Focusing specifically on the under-researched area of doctors as patients in a psychological context, this paper explores the processes underlying role transition as well as the therapeutic relationship that follows.

Furthermore, therapeutic reactions and adaptions of practice to this dynamic is also explored. A qualitative approach was employed and seven psychological therapists who had worked extensively with doctors as their patients were interviewed.

Subsequent interview data were thematically analyzed.

Six themes were generated: fear and pressure; status and control; variation of ideologies; change in practice; temporal changes; and help seeking and support.

The main barrier to recovery for doctors is difficulty in accessing services owing to the high-levels of stigma and shame that may be experienced. This research identifies some of the adaptions made by psychological therapists within their practice when working with doctors as patients.     

Cognitive-Emotional Interactions in the Brain

Abstract

Emotion and cognition are mediated by separate but interacting systems of the brain. The core of the emotional system is a network that evaluates (computes) the biological significance of stimuli, including stimuli from the external or internal environment or from within the brain (thoughts, images, memories). The computation of stimulus significance takes place prior to and independent of conscious awareness, with only the computational products reaching awareness, and only in some instances. The amygdala may be a focal structure in the affective network. By way of neural interactions between the amygdala and brain areas involved in cognition (particularly the neocortex and hippocampus), affect can influence cognition and cognition can influence affect. Emotional experiences, it is proposed, result when stimulus representations, affect representations, and self representations coincide in working memory.
