Language learning platforms or channels have always been a challenge and source of inspiration for the respective SLA researchers. The two widely used channels are learning exercises and tasks, which have received much research but which is more effective in developing language skills (listening here), is still controversial. Additionally, learners' features, including their learning styles, might be either an effective or an affected factor in applying either channel. To shed light on both problems, this experimental research employing 55 conveniently sampled Iranian intermediate EFL learners categorized into experimental and control groups was conducted. The experimental groups exposed to both pre-and post-tests received task- and exercise-based listening instructions separately for ten sessions. Their perceptual learning styles were also measured after the interventions. The respective parametric statistical analysis (i.e., independent-samples t-test) showed that both groups performed roughly equally in the post-test, and there was statistically no significant difference between intervention types. ANCOVA was run concerning each sub-style to address the status of the learning styles. Similarly, the relationship between listening ability and method type showed no statistically significant differences, regardless of whether the effectiveness of either treatment was natural. Both listening activities worked efficiently to enhance learners' listening comprehension abilities. Statistically speaking, the results confirmed the non-significantly differentiating effects of both independent variables on developing listening skills and modifying learning styles. The findings are more challenging rather than concluding, which, while bearing specific pedagogical insights, motivates further research.

Fatigue is a common and debilitating symptom among older adults, significantly impacting their quality of life and functional capacity. The relationship between serotonin and fatigue in aging is complex, involving multiple neurobiological pathways that influence sleep, mood, cognitive function, and energy metabolism. Understanding these mechanisms is crucial for developing effective management strategies. This review aims to elucidate the role of serotonin in the development of fatigue in elderly individuals and evaluate potential therapeutic strategies to mitigate this condition. A comprehensive review of recent literature was conducted, focusing on the neurobiological mechanisms linking serotonin to fatigue, the efficacy of pharmacological and non-pharmacological interventions, and future research directions. Studies were selected based on their relevance to serotonin’s role in aging and fatigue management. Serotonin plays a critical role in regulating various physiological and psychological functions that impact fatigue. Age-related declines in serotonin synthesis, receptor sensitivity, and transporter function contribute to increased fatigue through disrupted sleep, mood disorders, cognitive decline, and altered energy metabolism. Pharmacological treatments, including selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs), have shown efficacy in alleviating fatigue related to depression and chronic pain. Non-pharmacological interventions, such as cognitive behavioral therapy (CBT), exercise, sleep hygiene, and dietary modifications, are also effective in managing fatigue. Combining these approaches may offer the best outcomes for elderly patients. Addressing fatigue in older adults requires a multifaceted approach that integrates both pharmacological and non-pharmacological strategies. Personalized treatment plans considering individual patient profiles and preferences can enhance therapeutic efficacy. Future research should focus on exploring novel therapeutic targets within the serotonergic system, developing personalized medicine approaches, and evaluating the long-term impact of combined therapies.

Background: The effects of wearing common masks during maximal exercise activities on individuals remain unclear.Aim: This study aimed to examine the effect of wearing surgical and N-95 masks on physiological, perceptual, and performance responses in healthy men performing a maximal shuttle run test.Materials and Methods: Fifteen healthy men (age 23.78 ± 2.0) participated in three sessions: without a mask, with a surgical mask, and with an N-95 mask, with a one-week interval between each session. After each test, physiological variables (heart rate, blood lactate concentration, and oxygen saturation), perceptual variables (comfort/discomfort and perceived exertion), and performance variables (maximum oxygen consumption and shuttle run test duration) were measured. Data were analyzed using repeated measures ANOVA to compare differences between the conditions.Results: Significant differences were observed between the conditions with and without a mask in terms of oxygen saturation (P= 0.043), blood lactate concentration (P= 0.026), and perceived exertion, maximum oxygen consumption, and shuttle run test duration (P= 0.001), with the no-mask condition demonstrating superior outcomes in all variables. The type of mask (surgical or N-95) did not significantly affect the measured variables. Wearing both masks led to an increased sensation of moisture, heat, shortness of breath, and fatigue.Conclusion: Wearing masks, especially during intense physical activities, may impair physiological and performance metrics, recommending mask-free outdoor settings when feasible.
