People learn about others' feelings and emotions by picking up information they gather from physical appearance, verbal, and nonverbal communication.  Facial expressions, tone of voice, hand gestures, and body position or movement are just a few examples of ways people communicate without words.  A real-world example of social perception would be understanding that others disagree with what one said when one sees them roll their eyes.  There are four main components of social perception: observation, attribution, integration, and confirmation.

The native flora of the Saskatchewan includes vascular plants, plus additional species of other plants and plant-like organisms such as algae, lichens and other fungi, and mosses.  Non-native species of plants are recorded as established outside of cultivation in Saskatchewan, of these some non-native species remain beneficial for gardening, and agriculture, where others have become invasive, noxious weeds.  Saskatchewan is committed to protecting species at risk in Canada.  The growing season has been studied and classified into plant hardiness zones depending on length of growing season and climatic conditions.  Biogeographic factors have also been divided into vegetative zones, floristic kingdoms, hardiness zones and ecoregions across Saskatchewan, and natural vegetation varies depending on elevation, moisture, soil type landforms, and weather.  The study of ethnobotany uncovers the interrelation between humans and plants and the various ways people have used plants for economic reasons, food, medicine and technological developments.  The Government of Saskatchewan has declared 3 indigenous plants as provincial symbols. Organizational orientation is defined as an individual's predisposition toward work, motivation to work, job satisfaction, and ways of dealing with peers, subordinates, and supervisors on the job (Papa 2008).  It can also be referred to the different ways people approach their roles in an organization and the different approaches people have toward work and the place of work in their lives (organizational orientations).  Three organizational orientations have been identified as, upward mobile, indifferent, and ambivalent (Goodboy 2007).  These three types of orientations are associated with organizational communication behavior and organizational outcomes such as employee job satisfaction and motivation.  Presthus believed that these orientations results in employees having different orientations toward work itself, motivation to work, and job satisfaction (McCroskey 1998).

The Celts ( or , see pronunciation of "Celt" for different usages) were an Indo-European people in Iron Age and Medieval Europe who spoke Celtic languages and had cultural similarities, although the relationship between ethnic, linguistic and cultural factors in the Celtic world remains uncertain and controversial.  The exact geographic spread of the ancient Celts is also disputed; in particular, the ways in which the Iron Age inhabitants of Great Britain and Ireland should be regarded as Celts has become a subject of controversy. Poland in Antiquity is characterized by peoples belonging to numerous archeological cultures living in and migrating through various parts of the territory that now constitutes Poland in an era that dates from about 400 BC to 450–500 AD.  These people are identified as Celtic, Germanic, Baltic and Thracian tribes.  Other groups, difficult to identify, were most likely also present, as ethnic composition of archeological cultures is often poorly recognized.  While lacking use of a written language to any appreciable degree, many of them developed relatively advanced material culture and social organization, as evidenced by the archeological record, for example judged by the presence of richly furnished, dynastic "princely" graves.  Characteristic of the period was high geographical migration rate of large groups of people, even equivalents of today's nations.  This article covers the continuation of the Iron Age (see Bronze and Iron Age Poland), the La Tène and Roman influence and Migration periods.  La Tène period is subdivided into La Tène A, 450 to 400 BC; La Tène B, 400 to 250 BC; La Tène C, 250 to 150 BC; La Tène D, 150 to 0 BC.  400 to 200 BC is also considered the early pre-Roman period and 200 to 0 BC the younger pre-Roman period (A).  It was followed by the period of Roman influence, of which the early stage had lasted from 0 to 150 AD (0–80 B, 80–150 B), and the late stage from 150 to 375 AD (150–250 C, 250–300 C, 300–375 C).  375 to 500 AD constituted the (pre-Slavic) Migration Period (D and E).
