The effect of slow and fast music on selective attention in children with attention deficit/ hyperactivity disorder

This study examines the relationship between cognitive processes and job performance in teachers at the Cruz del Norte Educational Unit, focusing on attention, planning, organization, anxiety, and job stress. A mixed-method design was applied, combining quantitative and qualitative techniques such as psychometric tests, Pearson correlation, multiple regression analysis, Student’s t-test, the Delphi method, and the Ishikawa diagram. The results show that executive functions, particularly planning and organization, have a significant positive impact on job performance. Teachers with higher levels of these skills demonstrate better performance, with strong correlations (r = 0.72, p = 0.001; r = 0.65, p = 0.003). In contrast, anxiety and stress act as limiting factors. Multiple regression analysis indicates that anxiety (β = -0.4946, p < 0.0001) and stress (β = -0.3721, p < 0.001) negatively predict job performance. Additionally, job indiscipline—reflected in absenteeism and lateness—shows a strong negative correlation with performance (r = -0.74, p < 0.000). These findings highlight the importance of time management and organizational commitment, as well as the need to implement training and psychological support strategies to improve teacher performance and educational quality.

Abstract Child and adolescent externalizing problems have often been conceptualized broadly with imprecise language (e.g., “disruptive behavior”) or inconsistently across varying taxonomies (e.g., oppositional defiant and conduct disorder symptoms, aggressive and rule-breaking behaviors). Establishing clarity around dimensions of externalizing problems is an essential step toward more accurate measurement and construct validity across the externalizing domain. To that end, the current study investigated fine-grained dimensions in the structure of youth externalizing psychopathology. Caregiver-report survey data were collected for a national community sample of 576 youth (ages 6–14; 45% female, 25% Hispanic), including measures of irritability, oppositionality, reactive and proactive aggression, conduct problems, hyperactivity/impulsivity, and inattention. We used exploratory factor analysis (EFA) to examine relations among externalizing dimensions at the item-level followed by confirmatory factor analysis (CFA) to examine relations at the construct-level. EFA results suggested that a 3-factor model best fit the data, including factors characterized by externalizing affect (e.g., “felt mad”), externalizing behavior (e.g., “bullies, threatens, or intimidates others”), and ADHD symptoms (e.g., “talks excessively”), with a few cross-loadings. Similarly, confirmatory models indicated that a 3-factor, non-hierarchical structure fit the data best when compared to three other models. Results provide support for distinct facets of the externalizing spectrum in child psychopathology, suggesting a preliminary direction for a unifying framework. These findings highlight the potential for future measurement research to further disentangle the distinct and overlapping facets of externalizing constructs, particularly using multiple methods and informants and with replication across samples.

Music has been investigated as a potential influence on exercise performance, perceived exertion, recovery, and sleep. However, studies vary in their interventions, populations, exercise contexts, and measured outcomes. This scoping review aimed to map experimental evidence on music interventions in resistance, isometric and handgrip, aerobic exercise, acute recovery, and sleep, and to identify evidence gaps. PubMed/MEDLINE, SPORTDiscus, Scopus, and Web of Science were searched for studies published between 1980 and October 2026. Eligible studies involved human participants, compared a music intervention with a control or alternative condition, and reported exercise performance, perceived exertion, psychological responses, physiological recovery, or sleep outcomes. Screening was conducted using Rayyan. Findings were synthesised descriptively across four domains. Thirty studies involving 1,183 participants were included. Studies were published between 1981 and 2021 and examined resistance exercise (n=11), isometric and handgrip exercise (n=8), aerobic exercise and acute recovery (n=7) and sleep (n=4). The evidence maps a broad range of music interventions and outcomes, with variable findings across exercise and sleep contexts. Research gaps include limited participant diversity and insufficient investigation of sleep and recovery in athletic populations. Further studies are needed to clarify how music characteristics, individual preferences, and task demands relate to outcomes.

Reading achievement is influenced by a variety of cognitive and affective elements, with reading motivation and metacognitive awareness identified as two of the most important. This study examined (1) the relationship of students' reading motivation and reading achievement, (2) the relationship between metacognitive awareness and reading achievement, and (3) the combined contribution of reading motivation and metacognitive awareness to reading achievement among eleventh-grade students at SMAN 1 Sungai Lilin. Employing a quantitative correlational research design, The population for this research comprised 344 students enrolled in the eleventh grade from ten classes. Cluster random sampling was then applied to obtain a sample of 106 students. Data were gathered through the Motivation for Reading Questionnaire (MRQ), the Survey of Reading Strategies (SORS), and a reading achievement test. The obtained data were processed and analyzed using IBM SPSS Statistics version 25, which included descriptive statistics, Pearson product-moment correlation, partial correlation, and multiple regression. The findings showed that a positive relationship of moderate strength was associated with reading achievement (r = .600, p < .001), whereas metacognitive awareness demonstrated a strong positive relationship with reading achievement (r = .791, p < .001). In addition, the partial correlation analysis revealed a significant but weak positive association between reading motivation and metacognitive awareness after controlling for reading achievement (r = .304, p = .002). Reading motivation and metacognitive awareness explained 64.5% of the variation associated with reading achievement (R² =.645), according to the multiple regression analysis. These findings underscore the important roles of both reading motivation and metacognitive awareness in supporting students' reading achievement and suggest that both factors should be explicitly integrated into reading instruction to enhance students' reading performance
