Perceptual fluency and recognition judgments in haptic information processing

Area of Science:

• Cognitive Psychology
• Neuroscience
• Human-Computer Interaction

Background:

• Perceptual fluency, the ease with which information is processed, influences cognitive judgments.
• Prior research has established links between perceptual fluency and memory in various sensory modalities.

Purpose of the Study:

• To investigate the role of haptic perceptual fluency in recognition memory.
• To determine if tactile exploration ease affects judgments of prior experience.

Main Methods:

• Thirty-two participants were presented with objects.
• Object haptic exploration ease was systematically varied.
• Recognition memory judgments were collected for the presented objects.

Main Results:

• Objects easier to explore haptically were more frequently misjudged as previously encountered.
• A significant correlation was found between haptic exploration fluency and false recognition rates.
• This finding extends the perceptual fluency-memory link to the tactile domain.

Conclusions:

• Haptic perceptual fluency can lead to illusory recognition, suggesting a shared mechanism across senses.
• The ease of tactile exploration impacts memory recall and familiarity judgments.
• Findings have implications for understanding sensory integration in memory and designing haptic interfaces.
