This article is distributed under the terms of the Creative Commons Attribution 4.0 International The broad diagnostic category of DSM Major Depressive Disorder (MDD) was established in 1980 – in practice it seems that MDD can be interpreted as inclusive of patients with a wide range of dysphoric feelings including depression, anxiety, mood swings and emotional blunting/ unemo...

Economic theory reduces the concept of rationality to internal consistency. As far as beliefs are concerned, rationality is equated with having a prior belief over a “Grand State Space”, describing all possible sources of uncertainties. We argue that this notion is too weak in some senses and too strong in others. It is too weak because it does not distinguish between rational and irrational be...

Economists claim that principles of rationality are normative principles. Nevertheless, they go on to explain why it is in a person’s own interest to be rational. If this were true, being rational itself would be a means to an end, and rationality could be interpreted in a non-normative or naturalistic way. The alternative is not attractive: if the only argument in favor of principles of ration...

Economic theory reduces the concept of rationality to internal consistency. The practice of economics, however, distinguishes between rational and irrational beliefs. There is therefore an interest in a theory of rational beliefs, and of the process by which beliefs are generated and justified. We argue that the Bayesian approach is unsatisfactory for this purpose, for several reasons. First, t...

PURPOSE The relationship between dental fear and temperament in children was investigated in 124 Swedish children aged 5-7 and 10-12 years. They represented dentally fearful (65) and not fearful (81) children, and were drawn from a larger population-based patient pod. The aims of the investigation were to study the relationships between temperament on one hand, and dental fear and dental behavi...

Psychological traits are commonly inferred from covariation in sets of behavioral measures that otherwise appear to have little in common. Emotionality in mice is such a trait, defined here by covariation in activity and defecation in a novel environment and emergence into the open arms of an elevated plus maze. Behavioral and quantitative trait analyses were conducted on four measures obtained...

mega city-regions or metropolitan regions- that was introduced for the first time in a cabinet article in 1995- are becoming a dominant form of human settlements both in developed and developing countries. despite of all contentious discussion on economic and demographic significance of metropolitan regions and so rationality of establishing a distinct structure for their effective management a...

BACKGROUND Difficult temperament in infancy is a risk factor for forms of later internalizing and externalizing psychopathology, including depression and anxiety. A better understanding of the roots of difficult temperament requires assessment of its early development with a genetically informative design. The goal of this study was to estimate genetic and environmental contributions to individ...

Frontal EEG asymmetry patterns represent markers of individual differences in emotion reactivity and regulation, with right hemisphere activation linked with withdrawal behaviors/emotions (e.g., fear), and activation of the left hemisphere associated with approach (e.g., joy, anger). In the present study, gender was examined as a potential moderator of links between infant temperament at 5 mont...
