Shut-up Toys for Second Language Learners: Impact of Digital Media on Early Adolescents' Private Speech Production in Individual and Collaborative Tasks

Researchers, parents, and policymakers from previous generations have recently expressed concern about the inevitable exposure of youngsters to digital media and its potentially detrimental effects on their development. Private speech is the overt audible self-talk people produce when engaged with challenging problem-solving tasks and is believed to aid in second language acquisition as reported (Vygotsky in Thought and language, MIT Press, 1962); (Winsler in Private Speech, Executive Functioning, and the Development of Verbal Self-Regulation, 2009). This qualitative case study explored private speech production in three young adolescents (two 11-year-olds and one 10-year-old) while completing an English as a foreign language task (Bingo! game) individually and collaboratively in physical and digital modes. Patterns of participants' private speech markers emerged from a thematic analysis of the transcribed oral interactions during eight sessions. The frequency of occurrence of the participants' private speech markers was reported and interpreted based on the emergent typology to compare collaborative and individual task completion in physical and digital modes. Regardless of the individual or collaborative nature of the task, private speech use decreased during the digital version of the game. However, collaborative tasks evoked more private speech from the participants regardless of modality. The findings of the study suggest digital media usage is likely to hinder private speech production for self-regulatory purposes in young adolescents, even in collaboration with peers.

Children's Internet use and physical and psychosocial development

Introduction

Internet use (IU) commonly refers to sedentary lifestyle and may be addictive, especially among children. The aim of this study was to investigate the relationship between IU and some aspects of child physical and psychosocial development.

Methodology

We conducted a cross-sectional survey by using a screen-time based sedentary behavior questionnaire and Strengths and Difficulties Questionnaire (SDQ)-among 836 primary school children in the Braničevo District. The children's medical records were analysed for vision problems and spinal deformities. Their body weight (BW) and height (BH) were measured and body mass index (BMI) was calculated as BW in kilograms divided by BH in meters squared (kg/m²).

Results

The average age of respondents was 13.4 (SD 1.2) years. The mean duration of daily Internet use and sedentary behavior was 236 (SD 156) and 422 (SD 184) minutes, respectively. There was no significant correlation between daily IU and vision problems (near sightedness, farsightedness, astigmatism, strabismus), and spinal deformities. However, daily Internet use is significantly associated with obesity (p < 0.001) and sedentary behavior (p = 0.01). There was significant correlation between emotional symptoms with total Internet usage time, and total sedentary score (p < 0.001 for both, r = 0.141 and r = 0.132, respectively). There was a positive correlation between the total sedentary score of children and hyperactivity/inattention (r = 0.167, p < 0.001), emotional symptoms (r = 0.132, p < 0.001), and conduct problems (r = 0.084, p < 0.01).

Conclusion

In our study, children's Internet use was associated with obesity, psychological disturbances and social maladjustment.

The effect of computer use on the occurrence of migraine

Background/Aim. Risk factors concerning computer use-related migraine onsets are still unknown. The aim of this study was to determine the prevalence of headaches in computer users as well as the effects of computer use and behavior on the prediction of migraine presence. Methods. A cross-sectional study included 1,500 subjects from the general population who were given a questionnaire to assess the presence and type of headache and questions regarding computer-assisted behavior. All examinees were divided into two groups: the first group consisted of respondents who had a headache, and the second group consisted of subjects without a headache. Results. A total of 67.9% of the subjects had a headache, of which 23.9% had a migraine. Results of multinomial regression analysis showed that significant predictors of the migraine group, compared to the group without headache, were gender (female) and family anamnesis positive for migraine, as well as spending more time on the computer, making shorter and infrequent breaks in which physical activities were less included. Furthermore, members of the migraine group, compared with the group with other types of headaches, were younger and had family anamnesis, rarely made pauses during computer use, and their pauses were shorter. Conclusion. Improper and excessive computer use could be considered a risk factor for migraine occurrence, particularly in young people who have positive family anamnesis for migraine.

Prevalence of mobile device-related lower extremity discomfort: a systematic review

Mobile device users often experience musculoskeletal discomfort due to the intensive use of these devices in static body postures. Prolonged sitting and standing at work and in free time are risk factors for various diseases and all-cause mortality. Prolonged static postures are the main cause of lower extremity discomfort. A systematic search of the articles was conducted in four different electronic databases. All selected papers were appraised using a critical appraisal tool. Fourteen studies were selected for the review. The prevalence of musculoskeletal complaints ranged from 0.4 to 72.9%. Mobile device-related lower extremity discomfort ranged from 0.4 to 9.6%. The most common body posture among mobile device users in the selected studies was sitting. There is some evidence for the association between lower extremity pain and mobile device use. Experts should take this review as a basis to provide appropriate and effective ergonomic measures, especially for working mobile device users.

Rights, justice, and equity: a global agenda for child health and wellbeing

Worldwide challenges to child health and wellbeing are rapidly becoming existential threats to children and childhood. Inequities, armed conflict and violence, nuclear proliferation, forced migration, globalisation, and climate change are among the global issues violating children's rights to optimal survival and development. Child rights-based approaches will be required to enhance the response to the civil-political, social, economic, and cultural determinants of these global child health issues. In this Viewpoint, we present a global agenda for child health and wellbeing as a blueprint for the practice of paediatrics and child health in the domains of clinical care, systems development, and policy formulation. This global agenda is grounded in the principles of rights, justice, and equity and can address the root-cause determinants of health. The 30th anniversary of the UN Convention on the Rights of the Child is a relevant moment to recommit to shared goals for children's health and wellbeing.

Effects of electronic device overuse by university students in relation to clinical status and anatomical variations of the median nerve and transverse carpal ligament

INTRODUCTION

This study investigates the results of a questionnaire, provocative tests, and ultrasonographic measurements of carpal tunnel morphological parameters in intensive and nonintensive electronic device users.

METHODS

Forty-eight university students (equal numbers of intensive and nonintensive users, ≥5 h/day and <5 h/day of electronic device usage, respectively) were randomly selected after questionnaire responses were received and evaluated clinically and by ultrasonography. All participants were right-handed.

RESULTS

Intensive users had significantly more positive results in Phalen's and Durkan's tests and reported more wrist/hand pain compared with nonintensive users (P < 0.05). Intensive users also had significantly larger median nerve cross-sectional areas, flattening ratios, and perimeters as well as greater bowing of the transverse carpal ligament compared with nonintensive users (P < 0.05).

DISCUSSION

Overuse of electronic devices may adversely affect the median nerve within the carpal tunnel and the transverse carpal ligament, resulting in numbness, tingling, and pain in the hand. Caution may be warranted when using handheld electronic devices. Muscle Nerve 56: 873-880, 2017.
