I have been reading motivational articles how behavior is influenced by motivational factors eg. enviornment, learning, peers but how are they distinguished to allow us determine someone's character??
Could you explain a little more about what you mean by "character"? I see you have "characterisation" as one of your key words. Is this about characterizing a particular behavior or outcome of interest.
Thanks for the further detail. Perhaps others may suggest more, but I might direct you to a few motivational theories which have been used to explain (and predict) intentions and behavioural outcomes.
1) Expectancy-value theory (EVT) is one of the most influential theories for explaining individual behaviour and choice in achievement-related tasks (e.g., educational, occupational, leisure activities, etc.), persistence in such tasks, and performance in carrying them out (Eccles-Parsons et al., 1983; Wigfield, Tonks, & Klauda, 2016). It presents a substantive theoretical perspective that provides a “place” for characteristics and influences you list above.
2) Goal Theory - Achievement goal theory focuses on individuals’ purposes for engaging in the achievement task as the basis for their motivation, emphasizes the environment goal structure as influencing students’ construction of these purposes (Ames, 1992; Dweck, 1986; Elliott & Dweck, 1988).
3) Self-determination theory (SDT) – A theory that is specifically framed in terms of social and environmental factors that facilitate versus undermine intrinsic motivation.(Ryan & Deci, 2000). A good background read is (Vansteenkiste, Niemiec, & Soenens, 2010).
4) Social cognitive career theory (SCCT) – This is a self-efficacy theory that applies to career and related choice (Bandura, 1989; Lent, Brown, & Hackett, 1994).
These are just a few within the achievement choice framework (or closely related). Personally, I find a great deal of empirical evidence abounds for EVT, plus it has a very extensive framework of constructs.
