Emotions as agents of social influence: insights from Emotions as Social Information (EASI) theory

Emotion is part and parcel of social influence. The emotions people feel shape the ways in which they respond to persuasion attempts, and the emotions people express influence other individuals who observe those expressions. This chapter is concerned with the latter type of emotional influence. Such interpersonal effects of emotional expressions are quite different from the traditionally studied intrapersonal effects of emotional experience. This calls for a new theoretical approach that is dedicated specifically to understanding the interpersonal effects of emotional expressions. I summarize emotions as social information (EASI) theory, which posits that emotional expressions shape social influence by triggering affective reactions and/or inferential processes in observers, depending on the observer’s information processing and the perceived appropriateness of the emotional expression. I review supportive evidence from various domains of social influence, including negotiation, leadership, attitude change, compliance, and conformity in groups. Differences and commonalities with traditional intrapersonal frameworks are discussed

Pines

Pinus is the most important genus within the Family Pinaceae and also within the gymnosperms by the number of species (109 species recognized by Farjon 2001) and by its contribution to forest ecosystems. All pine species are evergreen trees or shrubs. They are widely distributed in the northern hemisphere, from tropical areas to northern areas in America and Eurasia. Their natural range reaches the equator only in Southeast Asia. In Africa, natural occurrences are confined to the Mediterranean basin. Pines grow at various elevations from sea level (not usual in tropical areas) to highlands. Two main regions of diversity are recorded, the most important one in Central America (43 species found in Mexico) and a secondary one in China. Some species have a very wide natural range (e.g., P. ponderosa, P. sylvestris). Pines are adapted to a wide range of ecological conditions: from tropical (e.g., P. merkusii, P. kesiya, P. tropicalis), temperate (e.g., P. pungens, P. thunbergii), and subalpine (e.g., P. albicaulis, P. cembra) to boreal (e.g., P. pumila) climates (Richardson and Rundel 1998, Burdon 2002). They can grow in quite pure stands or in mixed forest with other conifers or broadleaved trees. Some species are especially adapted to forest fires, e.g., P. banksiana, in which fire is virtually essential for cone opening and seed dispersal. They can grow in arid conditions, on alluvial plain soils, on sandy soils, on rocky soils, or on marsh soils. Trees of some species can have a very long life as in P. longaeva (more than 3,000 years)
