Assessing the representational structure of softness activated by words

Area of Science:

• Psychology
• Material Science
• Sensory Perception

Background:

• Softness is a key material property perceived through direct interaction (haptic) and indirectly via vision or language.
• Prior experiences with soft materials form associations, shaping our mental representations of perceptual softness.

Purpose of the Study:

• To investigate the structure of representational space for softness when activated by words.
• To compare verbal representations with existing haptic and visual perceptual spaces.

Main Methods:

• An online study rated sensory aspects of soft materials presented as written names.
• Results were compared with previous studies using visual and haptic information.
• Correlation, Procrustes, and classifier analyses were employed.

Main Results:

• Representational spaces for verbally presented materials generally matched those from haptic and visual experiments.
• Verbal representations were more predictable from visual data than from haptic data.
• Material identification difficulties in haptic experiments were ruled out as a cause for discrepancies.

Conclusions:

• The representational space of perceived softness is multidimensional.
• Verbal cues for softness are more closely linked to visual perception than to haptic perception.
• Understanding the interplay between different sensory modalities is crucial for comprehending material perception.
