Mental simulation processes literally 'run' or 're-run' multimodal enactments of external sensory and motoric signals along with internally generated introspective events.
There is now good evidence to suggest that different structures are involved in the processing of internally generated versus externally generated events (Lieberman, 2007; Reiman et al., 1997), and this distinction is blurred by script-driven imagery procedures.
Creating alternative versions of reality seems to have parallels with recollecting the past and imagining the future in requiring the simulation of internally generated models of complex events.
Interestingly, CF thinking, like recalling the past and imagining the future, requires a person to simulate internal models of events and to compare these internally generated models with external reality (Knight and Grabowecky, 1995).
Some investors seem to have decided that, just as the spreads on corporate and mortgage-backed debt were driven down too far during the credit bubble, they may be too high now.Michael Mauboussin of Legg Mason, a fund-management group, reckons that less than 20% of all market crises arise from external events like terrorism or elections; most are internally generated.
DMN is considered to be involved in internally generated tasks, such as attending to environmental stimuli or anticipating upcoming events [ 9].
Close observation of internal experience was defined as awareness of internally generated stimuli, such as sensations, cognition, and emotions.
These findings are consistent with a generic role for the basal ganglia in internally generated predictions.
Second, we asked whether the generated simulation demonstrated that the participant successfully recombined the previously given information with internally generated events/thoughts/actions to form a (1) coherent, (2) logical, and (3) novel sequence of events.
