 Abstract | | |
Sustained attention (SA) is a vital function mediated by the right frontal - parietal cortex. The digit vigilance test (DVT) measures SA. Assessment of SA in students for their academic excellence is considered to be an essential part of a neuropsychological evaluation. The objective of this study is to determine SA in students undergoing training of integrated Yoga module (IYM). A total of 66 university students aged between 18-37 years participated in this study with a single group pre-post design. The DVT data was collected before and after the IYM. Statistical Package for Social Sciences version 19 was used for data analysis. The Kolmogorov-Smirnov test showed that the data were not normally distributed. The Wilcoxon's signed ranks test was used to compare means of data. The data analysis showed 11.66% decrease (P < 0.001) in total time taken for DVT and 31.90% decrease (P < 0.001) in error scores for DVT. The present study suggests that IYM can result in improvement of SA among students, thus paving the way for their academic excellence. Additional well-designed studies are needed before a strong recommendation can be made. Keywords: Academic excellence, integrated Yoga module, sustained attention, university students

| Introduction | |  |
Attention is an essential element of cognition and has been characterized in two ways, that is, either as a resource or capacity or as a skill of resource deployment. Sustained attention (SA) is the capacity to attend to a task in hand for a required period of time. It is closely associated with task difficulty or complexity. [1] SA is easier for simple tasks than complex tasks. It is closely associated with the mental effort required by the task in hand. [2] The capacities to study and listen to a lecture for an extended length of time are examples of SA. Various brain areas mediate attention, different ones being responsible for different types of attention. The right frontoparietal area mediates SA. Damage to the right prefrontal cortex is associated with poor SA. [3] Imaging studies have shown that vigilance tasks requiring SA activate a network of neurons in the right frontal and parietal cortices. [4] Previous reports on SA suggest that reduced anxiety can improve performance on tasks requiring SA [5] and Yoga's anxiety reducing effects [6] could also have facilitated this. Similarly, modern education system and Gurukula education system improve SA in school children, but Gurukula education system is more effective. [1] Several studies have been published analyzing the effect of different aspects of Yoga including physical postures and meditation on SA. Integrated Yoga module (IYM) consisting of physical postures (Asana), voluntary regulation of breathing (Pranayama), maintaining silence and visual focusing exercises (Trataka) improve attention span in school children. [7],[8],[9] However, the changes in SA that characterize the efficacy of IYM for university students have not been reported adequately. Hence, it the present study was designed to assess the efficacy of IYM for academic excellence in university students using digit vigilance test (DVT). The objective of this study was to assess SA using DVT in university students undergoing IYM.
| Materials and Methods | | |
Subjects
A total of 66 university students (28 males and 38 females) undergoing IYM with 28.03 ± 9.38 years of mean age participated in the present study.
Inclusion criteria
- Both male and females aged between 18-37 years were enrolled in the study.
Exclusion criteria
- Students with serious medical conditions
- Students taking medication, psychiatric drugs, alcohol or tobacco in any form
- Using any other wellness strategy.
Design
The study was designed as a Single group pre-post test and was carried out at Swami Vivekananda Yoga Anusandhana Samsthana (S-VYASA) University, Bangalore.
Informed consent
An informed consent was obtained from all the participants before initiating the study. The study was approved by the Institutional Review Board (IRB) of S-VYASA University.
Assessment
The DVT developed by Kelland and Lewis, which is a valid and reliable test to measure SA was used in the present study. [10] It consisted of numbers 1-9 arranged randomly in rows. [11] There were 30 digits per row and 50 rows per sheet [Figure 1]. The subjects were instructed to cancel the digits 6 and 9 as fast as they can. They were asked not to cross other digits and miss any of target digits. The total time taken to complete the test and errors made was noted. | Figure 1: Digit vigilance test Instructions: Please look at this sheet. There are different digits arranged in rows. The digits are randomly arranged. Please cancel the digits 6 and 9 as fast as you can. Do not cross other digits and be sure not to miss any of target digits. Do as fast as you can

Intervention
The IYM [12] of 21 days duration was practiced by all the subjects. The program was conducted in the serene and peaceful atmosphere of the S-VYASA University in a residential set up with a schedule starting from 5 AM to 10 PM. The Raja Yoga (yogic practices) in the form of Yogic Kriya (cleansing techniques), Asanas (postures), Pranayama (breathing techniques), Shavasana Abhyasa (relaxation), Dhyana (meditation), Bhaktiyoga (devotional sessions), Jnanayoga (discourses from experts), Karmayoga (daily 1 h of the session of selfless service in the university campus), Sattvika diet (high-fiber low-fat vegetarian and balanced diet) and cultural events were the key essence of this program. The program was based on the integrated approach of Yoga therapy developed at S-VYASA University for holistic development of personality.
Data collection
The DVT data was collected before and after 21 days of the IYM.
Data analysis
The subjects were asked to cancel out digits 6 and 9. The time to complete the test along with the number of correct responses and errors was noted. [10],[11] Statistical analysis was performed with the help of Statistical Package for Social Sciences version 19. The Kolmogorov-Smirnov test showed that the data was not normally distributed. Hence, Wilcoxon signed ranks test was used to compare means of the data collected before and after the IYM.
| Results | | |
The data analysis showed 11.66% decrease (P < 0.001) in total time taken and 31.90% decrease (P < 0.001) in error scores for DVT [Table 1].
| Discussion | | |
Yoga has emerged as a treatment modality to reduce cognitive deficits, with the expectation that improvement of cognition would result in clinical improvement as well as improvement of psychosocial functioning. [13],[14] Improvement of psychosocial functioning not only require SA, but also visual scanning and activation and inhibition of rapid responses. Decrease in total time taken and error scores in DVT following IYM suggest improvement in SA. Thus, the present study suggests a significant increase in SA scores in university students following IYM. The DVT requires selective and SA as well as the ability to shift attention. [15] The mechanism underlying the improvement of SA may be related to the fact that IYM is associated with increased sympathetic activity and increased sympathetic tone is associated with better vigilance. [16] Moreover, previous study on Yoga reported enhanced SA as a result of the practice of Yogic way of life. The result indicates the importance of Yoga to improve academic excellence. [8],[9] The present study is consistent with these findings, suggesting that a systematic practice of the Yoga may enhance SA, which leads to academic excellence.
| Conclusion | | |
The present study suggests that IYM enhances SA among students, thus paving the way for their academic excellence. Additional well-designed studies are needed before a strong recommendation can be made.
