Age discrimination

Age discrimination is or group on the grounds of age. Although theoretically the word can refer to the discrimination against any age group, age discrimination usually comes in one of three forms: discrimination against youth (also called adultism), discrimination against those 40 years old or older , and discrimination against elderly people.

In the United States, the Age Discrimination in Employment Act prohibits employment discrimination nationwide based on age with respect to employees 40 years of age or older. The Age Discrimination in Employment Act also addresses the difficulty older workers face in obtaining new employment after being displaced from their jobs, arbitrary age limits.

Melancholia

Melancholia (from Greek μελαγχολία - melancholia, it also has a number of other names: lugubriousness, from the Latin lug ere, to mourn; moroseness, from the Latin morosus, self-willed, fastidious habit; wistfulness, from old English wist: intent, or saturnine, see Saturn (mythology)), in contemporary usage, it is a mood disorder of non-specific depression, characterized by low levels of enthusiasm and eagerness for activity.

In a modern context, "melancholy" applies only to the mental or emotional symptoms of depression or despondency; historically, "melancholia" could be physical as well as mental, and melancholic conditions were classified as such by their common cause rather than by their properties. Similarly, melancholia in ancient usage also encompassed mental disorders which might now be classed as schizophrenias or bipolar disorders.

Non-human

Psychopathology in non-human primates has been studied since the mid 20th century. Over 20 behavioral patterns in captive chimpanzees have been documented as (statistically) abnormal for their frequency, severity or oddness - some of which have also been observed in the wild. Captive great apes show gross behavioral abnormalities such as stereotypy of movements, self-mutilation, disturbed emotional reactions (mainly fear or aggression) towards companions, lack of species-typical communications, and generalized learned helplessness. In some cases such behaviors are hypothesized to be equivalent to symptoms associated with psychiatric disorders in humans such as depression, anxiety disorders, eating disorders and post-traumatic stress disorder. Concepts of antisocial, borderline and schizoid personality disorders have also been applied to non-human great apes.

The risk of anthropomorphism is often raised with regard to such comparisons, and assessment of non-human animals cannot incorporate evidence from linguistic communication. However, available evidence may range from nonverbal behaviors - including physiological responses and homologous facial displays and acoustic utterances - to neurochemical studies. It is pointed out that human psychiatric classification is often based on statistical description and judgment of behaviors (especially when speech or language is impaired) and that the use of verbal self-report is itself problematic and unreliable.
