Effort expectation and strategic cue use in visual search

Area of Science:

• Cognitive Psychology
• Neuroscience
• Visual Perception

Background:

• Positive cues facilitate visual processing by signaling target features.
• The utility of negative cues, which indicate distractor features, is less understood due to potential mental effort costs.
• Previous research suggests cue effectiveness may depend on a trade-off between search effort reduction and the effort of using the cue.

Purpose of the Study:

• To investigate the influence of expected mental effort on the effectiveness of positive and negative visual cues.
• To examine how effort expectation interacts with actual task difficulty to affect visual search performance.
• To explore the subjective effort/benefit evaluation in cue utilization.

Main Methods:

• Manipulated effort expectation by varying the proportion of easy and difficult trials within blocks.
• Compared the impact of positive, negative, and neutral cues under controlled effort expectations.
• Assessed visual search performance and cue utilization across different conditions of expected and actual task difficulty.

Main Results:

• Benefits of positive cues increased with higher search effort.
• Negative cueing effects did not yield reliable performance benefits, irrespective of expected effort.
• Search performance was enhanced when expected effort aligned with actual task difficulty, particularly in difficult trials.

Conclusions:

• Effort expectation significantly modulates the benefits of positive cues in visual search.
• Negative cues appear ineffective in improving search performance, even when effort is anticipated.
• An interaction between effort expectation and task difficulty influences visual search, with a notable asymmetry favoring accurate effort prediction in difficult tasks.
