“…Research in mostly terrestrial settings, for example, has shown that people who are more sensitive to crowding tend to be more skilled in their activity (Needham, Rollins, & Vaske, 2005), visit more remote or backcountry areas (Needham, Rollins, & Wood, 2004), and are motivated to seek quietude (Absher & Lee, 1981). Attributes such as proximity or closeness, solitude, and interactions without disruptions also appear to influence perceptions of crowding (Hammitt, 1982;Hammitt & Madden, 1989;Twight, Smith, & Wissinger, 1981).…”
