According to a new study in the Journal of Consumer Research, consumers shopping for more than one person tend to pass on “guaranteed hits” in lieu of getting something unique for each person on their list.

“Having multiple recipients in mind not only means that more gifts are needed, but it may change what shoppers focus on when making gift selections,” write authors Mary Steffel (University of Cincinnati) and Robyn A. LeBoeuf (University of Florida). “Our research indicates that shoppers selecting gifts for more than one person at a time may focus on getting different gifts for each recipient rather than on simply getting what each would like best.”

This behavior is what the researchers term “overindividuation,” or the tendency for shoppers to select a variety of gifts even when they know the recipients won’t be comparing gifts. Ironically, this means that the more shoppers try to be thoughtful, the more likely they are to pass up gifts that would be better liked in favor of individuated gifts.

Consider someone giving a magazine subscription to two friends, both of whom are avid sports fans. Instead of getting both friends a sports magazine, the giver might select a technology magazine for the first friend and a travel magazine for the second, even though both friends might have preferred a sports magazine and even though the giver might have given a sports magazine to either friend if he or she were the only recipient.

In six experiments, the researchers asked shoppers to choose gifts for one or more person. In all of the studies, one gift item was pre-tested to be more appealing than the other available gift items. When shopping for one recipient, shoppers tended to choose the most appealing gift. However, when shopping for multiple recipients, shoppers tended to pass up the more appealing gift in favor of getting different gifts for each person.

“To help consumers from losing sight of what gifts people would most appreciate, we encourage gift givers to think about the type of gifts the recipient would most likely pick for themselves,” the authors conclude.

Zinc-PillsA meta-analysis of studies measuring blood concentrations of zinc in some 1,600 depressed subjects and 800 control subjects has found that zinc concentrations were significantly lower in the patients with depression. And in the studies that measured depressive symptoms, greater depression severity was associated with a greater relative zinc deficiency. The senior researcher was Krista Lanctot, Ph.D., of the University of Toronto, and results are published in Biological Psychiatry.

What the results mean from a clinical viewpoint, however, remains to be determined, the researchers point out. Since the literature on zinc and depression is largely limited to case-control and cross-sectional studies, it is not known whether depression creates a zinc deficiency or a zinc deficiency helps set the stage for depression. Zinc is an essential nutrient with multiple biological functions.

It is possible that depression creates a zinc deficiency, the researchers suggest, since appetite changes are a common component of major depression. One study of subjects with the disorder identified trends between lower zinc concentrations and weight loss and anorexia symptoms. On the other hand, a zinc deficiency can induce depressive-like behaviors in animals, which in turn can be reversed by zinc supplements, the researchers point out. Thus “the potential benefits of zinc supplementation in depressed patients warrant further investigation,” they note.

A wide variety of foods contain zinc. Oysters contain more zinc per serving than any other food, but red meat and poultry provide the majority of zinc in the American diet. Other good food sources include beans, nuts, certain types of seafood (such as crab and lobster), whole grains, fortified breakfast cereals, and dairy products.

A comprehensive overview of depression and how to offer optimal care to depressed patients can be found in the new American Psychiatric Publishing book, Clinical Guide to Depression and Bipolar Disorder: Findings From the Collaborative Depression Study.
