The power of imagination
Imagination, with insight and initiative, is necessary for life (Boyd, 1992). Without imagination, team cooperation leading to victory is impossible (Boyd, 1986; Osinga, 2007).
The imagination effect, along with the goal-free effect, the worked example effect, the split-attention effect, the redundancy effect, the modality effect, the completion effect, and the variability effect, is one of the main products of cognitive load theory (Sweller, 2004; van gog, et al. 2005).
Imagining tasks can be superior to studying them when the proper mental structurse already exists (Cooper, et al., 2001; Ginns, Chandler, & Sweller, 2003; Kalyuga, et al., 2003; Leahy & Sweller, 2005). The imagionation effect shows itself dual-channel audio and visual instruction, but not visual instruction alone (Tindall-Ford & Sweller, 2006). Likewise, the imagionation effect appears after integrated but not split-attention instructional presentation of materials (Leahy & Sweller, 2004).
What does all this mean? Stay tuned. For now, a bibliography is below.
