From the Lab: The Value of Touch

In yesterday’s blog post, we saw that the physical presence of a item (as compared to an image of it or a description of it), can lead to greater perceptions of the item’s value. As it turns out, this effect can be further enhanced by allowing the audience to touch the item.

In a 2007 study by Bianca Grohmann, Eric Spangenberg, and David Sprott, they found that when participants were allowed to touch a variety of products, they evaluated those products even more favorably than when the products were merely present. (Other studies have found that they were also more likely to buy them.) Their findings suggest a hierarchy of perceived value: a product that is touched > a product that is present > a product that is pictured > a product that is described. It also provides more evidence for the value of props, particularly when the audience is allowed to handle them.

Additional research has revealed several important caveats to this rule, however.

First, this hierarchy only holds true when the quality of a product is high. Obviously, when the quality of a product is low, touch will not improve perceptions of its value. In fact, when low quality products can readily be compared to high quality products, touch actually reduces perceptions of their value.

Second, allowing people to touch a product only increases their perception of its value when there is something of value about the product can be revealed by the touching. For example, while allowing people to touch a fluffy towel will increase its value, allowing people to touch a DVD case will not.

Third, if an object has been touched by other people first, people may actually impart lower value to it. In other words, touch by others can have a contaminating effect on the product. However, if someone highly attractive touches the product, this can actually increase its value.

From the Lab: Hug Your Spouse (Updated)

Yesterday, we saw that receiving social support from a friend can be an effective way to reduce speech anxiety. Today, we’ll look at another strategy that can be even more effective.

Today’s strategy comes from a 2007 study in Psychoneuroendocrinology. Like yesterday’s study, it was based on the Trier Social Stress Test (TSST), which includes preparing and delivering a 5 minute speech in which you pitch yourself as the best candidate for a job.

This study included one control group and two experimental groups. In the experimental group, participants (all of whom were married or cohabiting females) were asked to bring their partners (all male) with them. During the preparation period, their partners were told to give the participants support in one of two ways. One group was told to give the participants verbal social support, as in yesterday’s study. The other was told to give the participants physical social support in the form of a standardized shoulder massage.

Interestingly, in this study, verbal social support provided no benefit, a finding which the authors note is consistent with previous studies “indicating reduced responsiveness to verbal social support by a spouse in women.”* The shoulder massage, however, helped quite a bit, suggesting that physical social support can also be effective in reducing speech anxiety—perhaps even more effective! Whether it’s a shoulder massage, or even just a hug, receiving comforting touch from a loved one can make the task of speaking significantly less stressful.


* What should we take away from this finding? That it’s useless for husbands to verbally support their wives? Certainly not. Instead, what I’d take away from this is that everyone has different strategies that work for them. For some people, talking to a friend or their spouse will help a lot—for others, it won’t help at all. Or to reference another strategy from The Science of Speaking, some people think that power posing is ridiculous, while others maintain that it has completely changed their lives. As always, The Science of Speaking is a toolbox: pick the tools that work best for you.
