Final answer:
The correct answer is that as groups become more successful, their cohesiveness generally tends to increase due to reinforced unity and validation, whereas larger groups face higher risks for division and lowered cohesiveness. The correct option of choice is (A).
Step-by-step explanation:
Regarding the multiple choice question about group cohesiveness, the correct answer is A: as groups become more successful, their cohesiveness tends to increase. This is because success often leads to a stronger sense of unity and validation of the group's purpose and methods, fostering a more cohesive group environment.
Small groups, in particular, generally have strong internal cohesiveness due to the ease of interaction and the sense of connection among members.
Large groups, while being able to garner more attention for their goals, face higher risks of division and decreased cohesiveness as size increases. This could lead to a dilution of consensus (groupthink) and can also encourage social loafing. Additionally, in smaller groups, factors such as monitoring and enforcement are easier, and peer pressure is stronger, thereby reducing collective action problems.
