Yes, I Can: The Interplay of Need for Cognition and Task Confidence in Cognitive Task Performance.

Need for Cognition (NFC) refers to the enjoyment of and the search for intellectual challenges. Although numerous studies suggest associations between NFC and cognitive performance, the processes and factors that may mediate the relationship are not yet well understood. Based on the literature suggesting that self-efficacy (SE) expectancies mediate the relationship between NFC and cognitive performance, we sought to investigate this relationship systematically under controlled laboratory conditions.

Experiencing sweet taste is associated with an increase in prosocial behavior.

Taste may be the first sense that emerged in evolution. Taste is also a very important sense since it signals potential beneficial or dangerous effects of foods. Given this fundamental role of taste in our lives, it is not surprising that taste also affects our psychological perception and thinking.

Neural underpinnings of open-label placebo effects in emotional distress.

While placebo effects are well-known, research in the last decade revealed intriguing effects that placebos may have beneficial effects even when given without deception. At first glance, this seems paradoxical, but several studies have reported improvements in pain, depression, or anxiety. However, it still remains unclear whether these results represent objective biological effects or simply a bias in response and what neural underpinnings are associated with the open-label placebo effects.
