1. Statement of the Problem The main purpose of this study is to correlate the exposure to nature with positive effect on sustained attention. Specifically, this study aimed to answer the following questions 1. What are the Choice Reaction Time and Simple Reaction Time when exposed to nature in sustained attention before and after the intervention of the: 2. 1.1. control group and 1.1. experimental group What is the Choice Reaction Time and Simple Reaction Time of the participants in sustained attention in the pretest and posttest of the: 3. 4. 2.1. control group and 2.1. experimental group? Is there a significant mean-gain from the pretest to the posttest in of the: 3.1. control group and 3.1. experimental group? Is there a significant difference in the mean-gains in exposure to nature between the control and experimental groups? 5. What are the attitudes of the participants towards the exposure to nature as a positive effect? 6. Is there a relationship between the participants’ attitude towards exposure to nature and their sustained attention level? 7. What intervention may be proposed to enhance the sustained attention level? Null Hypotheses Ho1: There is no significant difference between the hypothetical and the actual means of the participants in sustained attention in the pretest and posttest of the: 1.1. control group (pre exposed to nature) and 1.2 experimental group (exposed to Nature). Ho2: There is no significant mean-gain from the pretest to the posttest in sustained attention of the: 2.1 control group and 2.2 experimental group. Ho3: There is no significant difference in the mean-gains in sustained between the control and experimental groups. Ho4: There is no significant correlation between the participants’ attitude towards sustained attention and its positive effect in exposure to nature Experimental Group Nature Control Group Pretest Simple Reaction Time (SRT, Vigilance) Choice Reaction Time (CRT, Vigilance) Post test Analysis and Interpretation of Data Conclusion and Recommendation 4 2. Statement of the Problem This study determined the actual Exposure to nature can promote a positive effect on sustained attention.. Specifically, this research gathered information to answer each of the following questions: 1. What is the demographic profile of participants in terms of: 1.1 Gender; 1.2 Age; 1.3 Length of exposure to nature ; and 1.4 Highest educational attainment 2. What is the extent exposed to nature of the participants in each of the following categories: 2.1. Attitudes;; 2.2. Attention; 3. What is the extent of indoor of the participants in each of the following categories: 3.1. Attitudes; 3.2. Attention; 4. Is there a significant difference in the extent of Exposed to nature of the participants when data are categorized according to: 4.1 Gender; 4.2 Age; 4.3 Length of exposure to nature; and 4.4 Highest educational attainment 5 5. Is there a significant difference in the indoor relaxing of the participants when data are categorized according to: 5.1 Gender; 5.2 Age; 5.3 Length of exposure to nature; 5.4 Highest educational attainment; and 5.5 Highest educational attainment 6. Is there a significant difference in the nature and indoor setting of the participants? Hypotheses This study posited the following research hypotheses: 1. There is no significant difference in the exposed to nature of the participants when data are categorized according to gender, age, length of exposure to nature, and highest educational attainment 2. There is no significant difference in the extent of relaxing indoors of the participants when data are categorized according to gender, age, length of exposure to nature, and highest educational attainment 3. There is no significant difference in exposed to nature and of relaxing indoors of the participants 6 Conceptual Framework Independent Variable Dependent Variable Relaxing Indoors Exposing to Nature 1.

What are the experiences of the participants in connection of their exposure to nature? 2. How do these participants cope with the challenges of the experience? 3. What insights can the participants of this study share their peers and to academe in general? Research Participants Using purposive criterion sampling, 13 participants will be invited to participate for the data collection process - six for the individual in-depth interviews and seven for the Focus Group Discussion to validate the findings. The sample size was based on the guidelines set by Creswell (2013) for phenomenological studies who recommended at least 5 to 25 informants to be interviewed until data saturation is achieved. In this study, the recruitment of participants was based on snowball sampling, with informal contacts being vital in accessing initial participants. No variables since it is a qualitative.
