# Sustainable behavior in the fishing cards digital game: a comparative analysis across extraction patterns

## TL;DR

This study uses a digital game to explore how people adjust their fishing behavior when resources become limited, showing more sustainable choices over time.

## Contribution

The study demonstrates how digital games can model sustainable behavior and support environmental education through observed changes in resource extraction patterns.

## Key findings

- Participants reduced use of the most powerful fishing card when resources were limited.
- InterResponse Time increased during limited resource phases, suggesting more thoughtful decision-making.
- The study highlights the potential of digital games to teach and analyze sustainable behavior.

## Abstract

Sustainability is achieved when resources are used to meet current needs without compromising their availability for future generations. This study examined fishing behaviors across age groups using the Fishing Cards digital game. Participants (N = 30) played 40 s rounds, using two types of cards to catch fish: one less powerful and the other with greater capacity for resource extraction. The game consisted of two phases. In Phase 1, resources were unlimited, allowing participants to fish freely. In Phase 2, resources were limited and could be depleted, potentially leading to defeat in the game. The research aimed to examine whether InterResponse Time (IRT) for fishing responses changed and how card selection patterns and resource availability influenced participants’ choices. Specifically, the goal was to observe how players achieved sustainability in Fishing Cards when resources became limited. Statistical analysis was conducted using Generalized Linear Mixed Models (GLMM). Findings showed a reduction in the selection of the most powerful card and an increase in IRT during the limited resource phase, indicating more sustainable extraction patterns. As resource availability decreased, participants were less likely to use the most powerful cards. The study contributes to understanding sustainable behavior in experimental analogs and highlights the potential of digital gaming for environmental education and sustainability. Limitations are acknowledged.
