在4个实验中，参与者被引导专注于积极结果的前景（接近预期）或消极结果的前景（回避预期），随后进行相对半球激活的行为测量。结果发现，方法，相对于回避相关的预期状态，产生更大的相对右（相对减少左）半球激活。实验3还表明，这种模式的激活被逆转时，接近和回避状态不仅是预期的，但也情绪激动。最后，实验4重复了先前的研究结果，证明了接近和回避预期状态对创造性和分析性问题解决的影响（R。S. Friedman & J.Forster，2001，2003），并提供了证据表明，这种影响是由相对半球激活的差异介导的。
In 4 experiments, participants were led to focus on either the prospect of positive outcomes (approach anticipation) or the prospect of negative outcomes (avoidance anticipation) and were subsequently administered behavioral measures of relative hemispheric activation. It was found that approach, relative to avoidance-related anticipatory states, produced greater relative right (diminished relative left) hemispheric activation. Experiment 3 additionally demonstrated that this pattern of activation was reversed when approach and avoidance states were not merely anticipatory but were also emotionally arousing. Finally, Experiment 4 replicated earlier findings demonstrating an influence of approach and avoidance anticipatory states on creativity and analytical problem solving (R. S. Friedman & J. Forster, 2001, 2003) and provided evidence that such effects are mediated by differences in relative hemispheric activation.
