We buy what we grasp: How our hands lead us to choose certain products. The things we touch while shopping can affect what we buy, according to new studies. The authors suggest that tactile exposure to the object "Activated the conceptual representation of that object, which then facilitated subsequent processing of the given object." Ref. Source 3y.
Okay, I can see that. It gives you another sense to make you want to buy. My bet is, if they could also stimulate another one or two of your senses in a positive way you'd be even more prone to buying it. I mean, it only makes sense the more of your senses that are stimulated positively the more apt you are to like something. So, one day we'll be out shopping and everything will feel like suede, smell like popcorn, sound like church bells when you touch it and look mahvalous… simply mahvalous.
