Bimanual Postural Similarity Facilitates Haptic Memory-Guided Reaching

This study investigates how haptic memory-guided reaching is affected by delay and arm posture similarity, finding that short delays reduce accuracy but longer delays do not when postures are similar.

Tool-sensed object information effectively supports vision for multisensory grasping

Actions obey Weber's law when precision is evaluated at goal attainment

The paper tests Weber's law in a two-finger pointing task and finds that the standard deviation of inter-finger separation increases with target distance, supporting Weber's law in action.

Not only perception but also grasping actions can obey Weber's law

This study shows that both perceptual estimates and grasping actions follow Weber's law, contradicting the idea of a perception-action dissociation in size uncertainty.

Visual uncertainty unveils the distinct role of haptic cues in multisensory grasping

The paper investigates how visual uncertainty affects multisensory grasping by manipulating haptic cues, showing that haptic position and size cues play distinct roles in integrating visual information.

A brief glimpse at a haptic target is sufficient for multisensory integration in reaching movements

The paper shows that a brief visual glimpse before movement onset is enough to improve endpoint precision through multisensory integration in reaching tasks.

Integration of haptics and vision in human multisensory grasping

The paper investigates how visual and haptic cues contribute to multisensory grasping and finds that combining haptic positional cues with visual cues achieves the same performance as full cue availability.
