In which group process does a member gain hope by observing others' progress?

The correct choice highlights the beneficial effect of observing others who are experiencing improvements in their situations, thereby fostering a sense of hope in members of the group. Instillation of Hope occurs when individuals see that others, who may have similar issues or struggles, make positive strides. This observation often motivates group members to believe in their capacity for change and progress, enhancing their own outlook and encouraging persistence in the face of challenges.

This group process is particularly important in therapeutic or support settings, as it cultivates an environment where individuals can draw strength and motivation from each other's successes. By feeling inspired by others, individuals may feel more empowered to set and pursue their own goals, contributing to their overall growth and healing journey.

In contrast, the other responses represent different concepts: Contagion refers to the influence of group dynamics and emotions spreading among members, Conflict Resolution involves the methods and strategies to address disputes, and Universality is the recognition that others share similar experiences, which provides comfort but does not directly lead to enhancing hope through observation of progress. Each of these concepts has significance in group processes, but they do not specifically focus on the hope derived from witnessing the successes of others as the instillation of hope does.
