Are correlations among behavioral decision making tasks moderated by simulated cognitive impairment?

Area of Science:

• Neuroscience
• Cognitive Psychology
• Psychometrics

Background:

• Behavioral decision making tasks are prevalent in research but lack clinical assessment tools beyond the Iowa Gambling Task.
• Low correlations among existing tasks suggest they measure unique decision-making components.
• The sensitivity of these tasks to simulated impairment remains largely unexamined.

Purpose of the Study:

• To investigate the relationships among various behavioral decision making tasks.
• To determine if simulated cognitive impairment influences these relationships.
• To assess the vulnerability of these tasks to invalid performance.

Main Methods:

• Two studies involving undergraduate participants (N=166 and N=130) were conducted.
• Participants either attempted their best or simulated specific conditions like ADHD or general cognitive impairment.
• A battery of performance validity tests (PVTs) and three behavioral decision making tasks were administered.

Main Results:

• Simulated impairment groups were not distinguishable from control groups on behavioral tasks.
• Few significant correlations were found among the decision making tasks across studies.
• The pattern of task relationships did not vary based on simulator status or PVT failure.

Conclusions:

• Current behavioral decision making tasks may not be sensitive to simulated cognitive impairment.
• These tasks appear to measure largely independent aspects of decision making.
• Further research is needed to develop robust clinical assessments for decision making.
