چکیده

Motor imagery (MI), the mental simulation of movement without execution, provides a behavioural tool to evaluate sensorimotor representations. However, its characterisation in young children remains debated. This study investigated age-related differences in MI across early primary school years using a multi-task battery. One hundred and eighteen children aged 5–8 years (61 females), spanning the final year of kindergarten (GSM), first grade (CP), second grade (CE1), and third grade (CE2), completed executed and imagined trials of five functional tasks (standing up, typical gait, precision gait, drawing, and cube handling). Psychometric properties of the battery were evaluated. To ensure feasibility, engagement with imagery tasks was verified by comparing executed-imagined consistency in complexity-duration structure (i.e., complex tasks take longer both when executed and when imagined). Age-related differences were evaluated in terms of execution–imagery isochrony and variability across classes. Internal consistency was excellent (α = .91–.98) and test–retest reliability ranged from moderate to excellent (ICC = .68–.92). Engagement increased by age but already exceeded 70 % in the youngest group. Isochrony improved with age for simpler, highly practised tasks (typical gait, standing up), whereas more complex tasks (precision gait, cube handling) showed stable performance across classes. Variability decreased with age, and older children’s performance became increasingly influenced by task complexity demands. Findings demonstrate that mental chronometry can reliably capture MI abilities in children as young as five, revealing both developmental gains and task-specific constraints. These results highlight the feasibility of MI assessment in early childhood, warranting the need for longitudinal neuroimaging approaches to clarify mechanistic insights.

چکیده به فارسی

تصویرسازی حرکتی (MI)، شبیه‌سازی ذهنی حرکت بدون اجرا، ابزاری رفتاری برای ارزیابی بازنمایی‌های حسی‌حرکتی فراهم می‌کند. با این حال، ویژگی‌های آن در کودکان خردسال همچنان محل بحث است. این مطالعه تفاوت‌های مرتبط با سن در MI را در سال‌های ابتدایی دبستان با استفاده از یک مجموعه چندتکلیفی بررسی کرد. صد و هجده کودک ۵ تا ۸ ساله (۶۱ دختر)، شامل سال آخر پیش‌دبستانی (GSM)، پایه اول (CP)، پایه دوم (CE1) و پایه سوم (CE2)، آزمون‌های اجراشده و تصویرسازی‌شده پنج تکلیف عملکردی (برخاستن، راه رفتن معمولی، راه رفتن دقیق، نقاشی و جابجایی مکعب) را کامل کردند. ویژگی‌های روان‌سنجی مجموعه مورد ارزیابی قرار گرفت. برای اطمینان از امکان‌سنجی، مشارکت در تکالیف تصویرسازی با مقایسه سازگاری اجرا-تصویرسازی در ساختار پیچیدگی-مدت زمان (یعنی تکالیف پیچیده‌تر هم در اجرا و هم در تصویرسازی زمان بیشتری می‌برند) بررسی شد. تفاوت‌های مرتبط با سن از نظر هم‌زمانی اجرا-تصویرسازی و تغییرپذیری بین پایه‌ها ارزیابی شد. انسجام درونی عالی بود (α = .91–.98) و پایایی آزمون-بازآزمون از متوسط تا عالی متغیر بود (ICC = .68–.92). مشارکت با افزایش سن بیشتر شد اما حتی در گروه سنی پایین‌تر نیز بیش از ۷۰٪ بود. هم‌زمانی برای تکالیف ساده‌تر و با تمرین بیشتر (راه رفتن معمولی، برخاستن) با افزایش سن بهبود یافت، در حالی که تکالیف پیچیده‌تر (راه رفتن دقیق، جابجایی مکعب) عملکرد پایداری در بین پایه‌ها نشان دادند. تغییرپذیری با افزایش سن کاهش یافت و عملکرد کودکان بزرگ‌تر به طور فزاینده‌ای تحت تأثیر پیچیدگی تکلیف قرار گرفت. یافته‌ها نشان می‌دهد که کرونومتری ذهنی می‌تواند به طور قابل اعتمادی توانایی‌های MI را در کودکانی به سن پنج سالگی اندازه‌گیری کند و هم پیشرفت‌های رشدی و هم محدودیت‌های وابسته به تکلیف را آشکار سازد. این نتایج امکان‌سنجی ارزیابی MI در اوایل کودکی را برجسته می‌کند و نیاز به رویکردهای طولی تصویربرداری عصبی برای روشن شدن بینش‌های مکانیکی را نشان می‌دهد.

Generasi ASIK: Mewujudkan Santri TKA/TPA Baitul Ma’ruf yang Aktif, Smart, Inovatif, dan Kritis melalui Pembelajaran Kreatif dan Menyenangkan

Putri Cahyani Agustine; Iis Juniati Lathiifah; Muhammad Tohir; Cyndi Rahmania; Apriani Apriani Jurnal Pelayanan dan Pengabdian Masyarakat (Pamas), 2026, Vol. 10, Issue 4, pp. 489-501 https://doi.org/10.52643/pamas.v10i4.7124

چکیده

The objective of this community service initiative is to assist parents and teachers in fostering a "Qur’anic generation" that is ASIK, a generation not only proficient in reciting the holy Qur’an but also skilled in language and logical reasoningthereby enhancing the quality of education in Pangkalpinang City. Based on observations and interviews conducted at the Baitul Ma’ruf Quran Education Center (TPA) in Pangkalpinang, several issues have been identified at the TKA/TPA, specifically concerning the quality of services and comfort, education, health, and social aspects. Students also need to develop an awareness of the importance of becoming critical and innovative individuals, so that they do not fall behind as the flow of information continues to accelerate. This community service initiative was carried out in three stages: preparation, implementation, and evaluation. The activities focused on four key aspects: the installation of an organizational structure board and signage for the TKA/TPA to address quality; literacy and numeracy programs (Smart) and religious outreach (Active) to support education; the preparation of traditional Bangka cuisine (Innovative) to promote health; and social outreach sessions (Critical) to foster social engagement among the participants. The activity was attended by 40 students from the Baitul Ma’ruf TKA/TPA (Islamic kindergarten/elementary Quran education center). The participant satisfaction evaluation yielded an average score of 89.28, falling into the "very satisfied" category. The improvement in participants' numeracy literacy skills is evidenced by the results of numeracy literacy assessments: the average score at the beginning of the program was 46.46, which increased to 73.73 following the numeracy literacy learning activities. The outcomes of the activity also included an improved understanding among participants regarding how to deliver a lecture, how to create calligraphy, and how to select natural ingredients native to the Bangka region that can be used to prepare local delicacies with health benefits

چکیده

Early Childhood Care and Development (ECCD) serve as a foundational framework for the holistic growth and lifelong learning of young children. In the Philippines, its implementation is mandated by Republic Act No. 10410 and strengthened by Republic Act No. 12199, which emphasize quality early childhood education delivered by competent Child Development Workers (CDWs) and supported by strong institutional systems; however, implementation continues to face challenges related to limited resources, professional development gaps, administrative constraints, and varying levels of community and parental involvement. This study examined the level of readiness and the challenges encountered by CDWs in implementing the ECCD Curriculum in Barangay Child Development Centers in the Municipality of Mabinay, Negros Oriental. A quantitative descriptive-correlational design was employed, using a validated researcher-made Likert-scale questionnaire administered to ten (10) purposively selected CDWs during School Year 2025–2026. Data were analyzed using frequency, percentage, weighted mean, and Pearson product-moment correlation at the 0.05 level of significance. Findings revealed that the respondents were highly ready in their understanding of the ECCD curriculum (WM = 4.28) and in pedagogical skills and instructional practices (WM = 4.28), but only moderately ready in terms of resources and materials (WM = 3.80) and support, supervision, and professional development (WM = 3.84). Challenges were generally moderate, with insufficient toys and learning materials, varied learning needs of children, and heavy workload and administrative tasks emerging as the most notable concerns. ECCD-related training showed a strong, significant positive relationship with readiness (r = 0.795, p = 0.006), whereas age, educational attainment, and years of experience were not significantly related to readiness, no profile variable was significantly related to the challenges encountered, and readiness was not significantly related to challenges (r = 0.081, p = 0.824). The study concludes that while CDWs are generally prepared to implement the ECCD Curriculum, their effectiveness is constrained by largely systemic and environmental challenges. These findings imply the need for continuous professional development combined with improved resource allocation, reduced administrative workload, strengthened institutional support, and stronger collaboration among local government units, parents, and community stakeholders.

Psychological Adaptation and Intervention Strategies for Generations Alpha and Beta: A Comparative Study on Evolving Lifestyles and Mental Health Needs

Sayyed Hashim International Journal of Science and Research (IJSR), 2026, Vol. 15, Issue 10, pp. 2119-2121 https://doi.org/10.21275/sr261029112315

چکیده

Generation Alpha (born 2010-2024) and Generation Beta (born 2025-2039) represent an unprecedented developmental archetype defined by total digital integration and ubiquitous artificial intelligence (AI). This empirical study evaluated specialized psychological adaptation mechanisms, parenting models, and mental health intervention frameworks across these cohorts. Utilizing a mixed-methods design, quantitative data were gathered from $N = 300$ parents (Gen Alpha parents and expectant/early Gen Beta parents) using the Modified Parental Stress Scale (PSS) and Child Behavior Checklist (CBCL), supplemented by qualitative interviews with $N = 20$ pediatric mental health experts. Independent samples $t$-tests confirmed that Gen Alpha/Beta display significantly higher digital dependency anxiety ($M = 38.60, p < .001$) alongside superior visual-spatial intelligence ($M = 44.10, p < .001$) relative to normative baselines. Crucially, a proactive "Digital Integration" co-navigation parenting framework yielded significantly lower parental stress ($M = 29.50$) compared to rigid "Digital Detox" restriction models ($M = 42.80, p < .001$). A preventive clinical framework focusing on Social-Emotional Learning (SEL) and cognitive impulse management is proposed.

Classroom Behaviour and Social Adjustment among School Students: A Theoretical Perspective

M Athira; Shivanand x International Journal of Science and Research (IJSR), 2026, Vol. 15, Issue 10, pp. 2115-2118 https://doi.org/10.21275/mr261029221149

چکیده

Children's behaviour and social adjustment within the classroom are important considerations. Behaviour can refer to how a pupil engages with learning tasks, follows instructions, works with others and interacts within the classroom. Social adjustment can relate to how children feel they fit in, build friendships, communicate effectively and feel included. Although behaviour and social adjustment are two distinct areas, they will be influenced by each other. This conceptual article will discuss the relationship between behaviour and social adjustment for upper primary school students. Using theories such as ecological systems, social learning and sociocultural. School engagement, friendships and school belonging will also be discussed. It is important to consider how behaviour should be seen as more than just an individual trait. Family factors, teaching style, peer relationships, individual differences and school factors can influence how a pupil behaves. A strength based approach to children's behaviour and social adjustment will be advocated. The article will conclude with key implications for classroom settings and recommendations for future research. Future research should be culturally aware, developmentally appropriate and ethical. This article is theoretical and will not give any findings.

The effect of authoritative parenting style on toilet training ability in children aged 3-4 years

Afi Funky Najuba; Siti Maimunah Cognicia, 2026, Vol. 14, Issue 2, pp. 98-104 https://doi.org/10.22219/cognicia.v14i2.45404

چکیده

Toilet training is an essential developmental process that fosters discipline and independence in early childhood. The acquisition of toileting skills is significantly influenced by parenting approaches. Authoritative (democratic) parenting, characterized by warmth, two-way communication, and clear boundaries, offers supportive guidance during this developmental transition. This study aimed to investigate the effect of an authoritative parenting style on toilet training ability among children aged 3–4 years. A quantitative research design with a correlational approach was employed, involving 206 parents of children aged 3–4 years selected via questionnaire distribution. Data were collected using the adapted Parenting Styles and Dimensions Questionnaire-Short Version (PSDQ-SV) and the Toilet Training Readiness Scale (TTRS), and analyzed using binary logistic regression. The results revealed a statistically significant association between authoritative parenting and toilet training outcome (p = .018, p .05), though accounting for a modest proportion of the overall variance. These findings suggest that while authoritative parenting contributes positively to early toilet training progression, consistent parental guidance and child-centered readiness factors remain vital.
