Effects of male postpartum depression on father–infant interaction: The mediating role of face processing

It is estimated that postpartum depression affects up to 25% of men. Despite such high prevalence, the majority of studies on postpartum depression are focused on mothers, and the role of paternal depression and its effects on infant development have been overlooked by researchers and clinicians. The present study aimed to fill this gap by investigating the effect of paternal postpartum depression on father–infant interactions. In addition, we examined whether differences in face recognition mediated the effects of paternal postpartum depression on father–infant interactions. A total of 61 father–infant dyads (17 postpartum depression, 44 controls) took part in the study. Results revealed that compared to controls, fathers with postpartum depression had a worse pattern of interaction with their infants on measures of responsiveness, mood, and sensitivity; they also had greater difficulty in recognizing happy adult faces, but greater facility in recognizing sad adult faces. Depressed fathers attributed greater intensities to sad adult and infant faces. The tendency to attribute greater intensity to sad adult faces was confirmed as a partial mediator of the effect of paternal postpartum depression on measures of father responsiveness and as a full mediator of the effects of paternal depression on father sensitivity. Clinical implications and suggestions for further studies are discussed.     

How valuable is a well‐crafted design and name brand?: Recognition and willingness to pay

Preferences for similarly designed consumer products, evaluated blind and branded and also with and without prices, were tested in a consumer setting. The consumer's perceptual experience led to preference of the well‐crafted high‐priced option. This preference was enhanced by priming consumers with background information about the brand, perhaps causing the subjects to guess which choice was the well‐known brand before evaluation. Preferences for that choice increased again when brand names were visible during evaluation. When actual prices were added to the evaluations, preferences for the well‐known brand were very robust to high prices, indicating the strength of the brand name. Using the least preferred option and the lowest price as an anchor, the consumers' price threshold to pay for the preferred design and the brand name was computed. Attempts to explain and predict individual differences of choices using measures of inherent design acumen, prior experience, and purchasing behavior were largely unsuccessful.
