Haptic picture recognition was tested in 36 undergraduate students to determine whether haptic representations are visual or multi-modal. Participants explored target haptic pictures and were asked to recognize the target from three alternatives. Each participant completed eight control and eight interference trials in visual, lexical and tactile recognition modalities. For interference, participants were assigned to either an articulatory suppression (repeat "the" at a constant rate) or a visual interference (watch a visual display) condition, to prevent recoding into a verbal or visual code. The results showed that accuracy was higher at control compared to interference trials and for tactile compared to lexical recognition. Additionally, lexical and tactile recognition decreased with articulatory suppression whereas only tactile recognition decreased with visual interference. These findings suggest that haptic pictures may be represented by coordinating visual and verbal codes.
触觉图片识别在 36 名本科生中进行了测试，以确定触觉表示是视觉的还是多模态的。参与者探索了目标触觉图片，并被要求从三个选项中识别目标。每个参与者在视觉、词汇和触觉识别模式下完成了 8 个控制和 8 个干扰试验。对于干扰，参与者被分配到发音抑制（以恒定的速度重复“the”）或视觉干扰（观看视觉显示）条件下，以防止重新编码为口头或视觉代码。结果表明，在控制试验中，与干扰试验相比，触觉识别的准确性更高，与词汇识别相比，触觉识别的准确性更高。此外，词汇识别和触觉识别随着发音抑制而降低，而只有触觉识别随着视觉干扰而降低。这些发现表明，触觉图片可能通过协调视觉和口头代码来表示。
