Documentary Heaven :: Food For Your Brain | Free Online Document The Little prince | V noci jsem snil, že jsem motýlem Once when I was six years old I saw a magnificent picture in a book, called True Stories from Nature, about the primeval forest. It was a picture of a boa constrictor in the act of swallowing an animal. Here is a copy of the drawing. In the book it said: "Boa constrictors swallow their prey whole, without chewing it. I pondered deeply, then, over the adventures of the jungle. I showed my masterpiece to the grown-ups, and asked them whether the drawing frightened them. But they answered: "Frighten? My drawing was not a picture of a hat.

Depressive realism Evidence for[edit] Evidence against[edit] When asked to rate both their performance and the performance of another, non-depressed individuals demonstrated positive bias when rating themselves but no bias when rating others. Criticism of the evidence[edit] Some have argued that the evidence is not more conclusive because there is no standard for "reality," the diagnoses are dubious, and the results may not apply to the real world.[33] Because many studies rely on self-report of depressive symptoms, the diagnosis of depression in these studies may not be valid as self-reports are known to often be biased, necessitating the use of other objective measures.
