Normality and abnormality

Defining Normality and Abnormality

Much of the practice and research conducted by clinical psychologists focuses on abnormality, also known as mental disorders, psychiatric diagnoses, or, more broadly, psychopathology. Through their training and their professional activities, clinical psychologists become very familiar with the definitions of various forms of abnormal behavior and the ways it differs from normal behavior. But be...

Normality and abnormality.

‘Normal’ comes from the latin norma, a carpenter’s square, and in mediaeval times meant something at a right angle or perpendicular. A few centuries later it came to mean conforming to a standard and was used in physics to refer to the average of a set of variables. If the variable concerned, such as head size or IQ, is continuous and has a normal distribution, by convention the normal range ha...

Critically assess attempts to distinguish psychological normality and abnormality

The abnormality as a deviation-from-the-average definition sees abnormality as statistically infrequent behaviour. Yet this does not distinguish between desirable and undesirable behaviour. Some behaviour can be seen as desirable yet be statistically infrequent, e.g. creative genius. Also there are behaviours that are so common that they are regarded as being statistically frequent, yet are cat...

Normality, Projective Normality and Egz Theorem

In this note, we prove that the projective normality of (P(V )/G,L), the celebrated theorem of Erdös-Ginzburg-Ziv and normality of an affine semigroup are all equivalent, where V is a finite dimensional representation of a finite cyclic group G over C and L is the descent of the line bundle O(1)⊗|G|.
