[Meta-cognitive beliefs about thought suppression and associated paradoxical effects].

The purpose of this study was to clarify the contents of meta-cognitive beliefs about thought suppression and to investigate the relationship between these beliefs and the paradoxical effects of thought suppression. In Study 1, we developed a scale measuring the endorsement of meta-cognitive beliefs about thought suppression. This measure, the Meta-cognitive Beliefs about Thought Suppression Questionnaire (BTQ, has four subscales: Distraction, Paradoxical Effect, Regret, and Promotion of Concentration.

Cold-hearted or cool-headed: physical coldness promotes utilitarian moral judgment.

In the current study, we examine the effect of physical coldness on personal moral dilemma judgment. Previous studies have indicated that utilitarian moral judgment-sacrificing a few people to achieve the greater good for others-was facilitated when: (1) participants suppressed an initial emotional response and deliberately thought about the utility of outcomes; (2) participants had a high-level construal mindset and focused on abstract goals (e.g.

Indelible distrust: memory bias toward cheaters revealed as high persistence against extinction.

Our ability to learn about the reputations of others-that is, who is likely to cooperate versus cheat-contributes greatly to cooperativeness in society. There has been recent debate whether humans employ memory bias favoring cheaters (i.e.

Kigamicins, novel antitumor antibiotics. I. Taxonomy, isolation, physico-chemical properties and biological activities.

Novel antibiotics named kigamicin A, B, C, D, and E were discovered from the culture broth of Amycolatopsis sp. ML630-mF1 by their selective killing activity against PANC-1 cells only under a nutrient starved condition. Under a condition of nutrient starvation, kigamicins A, B, C, and D inhibited PANC-1 cell survival at 100 times lower concentration than in normal culture.
