Based on research on the increasingly popular unconscious thought effect (UTE), it has been suggested that physicians might make better diagnostic decisions after a period of distraction than after an equivalent amount of time of conscious deliberation. However, published attempts to demonstrate the UTE in medical decision making have yielded inconsistent results. In the present study, we report the results of a meta-analysis of all the available evidence on the UTE in medical decisions made by expert and novice clinicians. The (...) meta-analysis failed to find a significant contribution of unconscious thought to the accuracy of medical decisions. This result cannot be easily attributed to any of the potential moderators of the UTE that have been discussed in the literature. Furthermore, a Bayes Factor analysis shows that most experimental conditions provide positive support for the null hypothesis, suggesting that these null results do not reflect a simple lack of statistical power. We suggest ways in which new studies could usefully provide further evidence on the UTE. Unless future research shows otherwise, the recommendation of using unconscious thought to improve medical decisions lacks empirical support. (shrink)

The coexistence of genetically modified (GM) crops and non-GM crops is a myth because the movement of transgenes beyond their intended destinations is a certainty, and this leads to genetic contamination of organic farms and other systems. It is unlikely that transgenes can be retracted once they have escaped, thus the damage to the purity of non-GM seeds is permanent. The dominant GM crops have the potential to reduce biodiversity further by increasing agricultural intensification. There are also potential risks to (...) biodiversity arising from gene flow and toxicity to nontarget organisms from herbicide-resistant (HT) and insect-resistant (Bt) crops. Unless whole regions are declared GM agriculture free, the development of distinct systems of agriculture (GM and non-GM) will be impossible as GM agriculture emerges at the expense of all other forms of production.

The purpose of this paper is to study Leonardo Polo's conception of the principle of identity. This identity is also called Origin; however, an adequate understanding of that expression requires a careful study of the way man comes to be aware of it.

Higher plants must undergo a major developmental switch, the transition to flowering, if they are to successfully complete their life cycle. In many plants, the crucial decision of when to begin to produce flowers is primarily controlled by environmental signals. The process of floral induction involves the integration of the activities of two types of genes: those that control flowering time as a response to the environment as well as an endogenous clock, and those that determine the floral identity of (...) the cells. The first direct link between these two classes of genes has now been demonstrated(1). Forced expression of CONSTANS, a flowering‐time gene, promotes flowering through the transcriptional activation of LEAFY, a flower‐meristem‐identity gene. (shrink)

This book aims to enrich our understanding of the role the environment plays in processes of life and cognition, from the perspective of enactive cognitive science. Miguel A. Sepúlveda-Pedro offers an unprecedented interpretation of the central claims of the enactive approach to cognition, supported by contemporary works of ecological psychology and phenomenology. The enactive approach conceives cognition as sense-making, a phenomenon emerging from the organizational nature of the living body that evolves in human beings through sensorimotor, intercorporeal, and linguistic (...) interactions with the environment. From this standpoint, Sepúlveda-Pedro suggests incorporating three new theses into the theoretical body of the enactive approach: sense-making and cognition fundamentally consist of processes of norm development; the environment, cognitive agents actually interact with, is an active ecological field enacted in their historical past; and sense-making occurs in a domain consisting of multiple normative dimensions that the author names enactive place.
