Difficulty: MediumIdentifying the Apparent Discrepancy

In a recent behavioral study, participants were divided into two groups and asked to solve a complex logic puzzle. Group A was offered a substantial financial reward if they completed the puzzle within one hour. Group B was offered no reward and was simply asked to try the puzzle for fun. Standard behavioral theories strongly predict that large financial incentives increase motivation, thereby leading to faster completion times on cognitive tasks. However, researchers recorded that a significantly higher percentage of participants in Group B successfully completed the puzzle within the hour compared to Group A.

Which one of the following most accurately describes the apparent discrepancy presented in the information above?

  1. Group A was provided with a financial incentive predicted to improve cognitive task performance, yet they achieved a lower success rate than Group B, who received no such incentive.Answer
  2. B
    A significant number of participants in Group A failed to complete the logic puzzle within the allotted hour, even though they were offered a substantial financial reward.
  3. C
    The pressure of a substantial financial reward induced performance anxiety in Group A, which impaired their cognitive function and resulted in fewer completed puzzles.
  4. D
    Standard behavioral theories predict that financial rewards increase motivation, but these theories fail to account for the fact that completing puzzles is inherently enjoyable for most people.
  5. E
    Financial incentives consistently decrease performance on all complex cognitive tasks, whereas performing a task strictly for fun guarantees a higher rate of success.

Answer

The correct answer is the option stating that Group A was provided with a financial incentive predicted to improve performance, yet they achieved a lower success rate than Group B.
The correct answer perfectly captures the logical tension presented in the stimulus. Standard theory predicts that the financial reward given to the first group should lead to better performance. The discrepancy arises because the second group, which lacked this supposedly advantageous incentive, actually completed the puzzle at a significantly higher rate. This option isolates both halves of the surprising contrast without attempting to explain the underlying cause.

Step-by-Step Solution

1
Analyze the stimulus to isolate the two conflicting sets of facts.
Fact 1: Group A had a financial incentive (predicted by theory to increase success), and Group B had none. Fact 2: Group B had a higher success rate than Group A.
Identifying a discrepancy requires clearly defining the expectation versus the reality.
2
Evaluate the specific task requested by the question stem.
The question asks only to describe the apparent discrepancy.
It is critical to distinguish between identifying a paradox and resolving one. The correct answer must state the conflict, not explain its cause.
3
Review the options to find the precise description of the logical tension.
The correct option successfully contrasts the expectation set by the financial reward for the first group with the surprising reality of the unrewarded group's superior performance.
Other options attempt to explain the cause, focus only on one group's failure, or make unwarranted universal generalizations.

Key Concept
