This experiment will test how attention manipulations affect individual problem-solving strategies. Specifically, in the case of ill-structured, complex, and novel problems. The experiment has two aims. First to show that problem-solving strategies are prone to attention manipulations. Second to show that manipulations can shift problem-solving strategies in predictable ways. In doing this, we are performing a direct replication of a prior experiment to strengthen the case for the prior results. The study mainly consists of two ill-structured, complex, and novel problems. The two tasks employ each a problem description and a set of 10+ items the participants need to rank-order in terms of importance to the survival goal in the problem-situations. The presence of multiple and interdependent items makes the problems complex. The absence of clearly defined alternatives makes the problem ill-structured. To make the problem novel, we select participants who lack survival training, so that participants need to solve the problems using new approaches. The experiment will have a mixed factorial design whereby there will be three groups of participants (two manipulation conditions and one control condition) and within each group, the participants will perform two tasks. The first task is done before the manipulation and is the same for all participants. Therefore, the behavior between conditions should be equivalent. The manipulation happens after the first task is finished. The second task is the same for all participants so we can compare the change in behavior of the participant in the second task relative to their behavior in the first task between the conditions. In other words, the hypotheses of the experiment focus on the standardized change in behavior and performance before and after the manipulation between the experimental conditions.

This experiment will test how attention manipulations affect individual problem-solving strategies. Specifically, in the case of ill-structured, complex, and novel problems. This experiment is a replication of the experiment preregistered at: https://osf.io/nvfdc The goal of this project is to implement post-hoc manipulation checks to show that the espoused decision policies employed by the participants are directed by the manipulations of the experiment. The experiment has a smaller sample than the one described at https://osf.io/nvfdc and will not collect data on the pandemic control variables. We remove these control variables because the aim of this experiment is not to replicate the results of the previous study but to show how the manipulation affects the participant's espoused decision policy. In this way, the hypotheses of the experiment are different.
