The field perspective, functionally connected with a concrete level of goal/action identification (Libby et al., 2009), resulted in faster recovery from a negative event.
Fifth, inducing an abstract level of identification produces greater self-control on experimental tasks than inducing a concrete level of identification (Fujita, Henderson, Eng, Trope, & Liberman, 2006).
Thus, there is considerable theoretical rationale for level of goal/action identification influencing self-regulation in clinical contexts, with a concrete level-of-identification implicated in poorer resistance to temptation.
Analysis and experiments have shown that hierarchical problem solving is most effective when the hierarchy satisfies the downward refinement property (DRP), whereby every abstract solution can be refined to a concrete-level solution without backtracking across abstraction levels.
What's more, the house had a finished basement, with stone walls and a concrete floor that was completely level.
Moreover, since control theory accounts hypothesize that mood is a function of relative goal progress, with negative versus positive affect resulting from less versus greater progress towards a goal than desired and expected (Carver & Scheier, 1990), it is hypothesized that negative affect would be associated with a shift to a more concrete level of goal/action identification.
