Motion adaptation and attention: a critical review and meta-analysis
The motion aftereffect (MAE) provides a behavioural probe into the mechanisms underlying motion perception, and has been used to study the effects of attention on motion processing. Visual attention can enhance detection and discrimination of selected visual signals. However, the relationship between attention and motion processing remains contentious: not all studies find that attention increases MAEs. Our meta-analysis reveals several factors that explain superficially discrepant findings.Across studies (37 independent samples, 76 effects) motion adaptation was significantly and substantially enhanced by attention (Cohen’s d=1.12, p<.0001). The effect more than doubled when adapting to translating (vs. expanding or rotating) motion. Other factors affecting the attention-MAE relationship included stimulus size, eccentricity and speed. By considering these behavioural analyses alongside neurophysiological work, we conclude that feature-based (rather than spatial, or object-based) attention is the biggest driver of sensory adaptation.Comparisons between naïve and non-naïve observers, different response paradigms, and assessment of ‘file-drawer effects’ indicate that neither response bias nor publication bias are likely to have significantly inflated the estimated effect of attention.

Abstract

The motion aftereffect (MAE) provides a behavioural probe into the mechanisms underlying motion perception, and has been used to study the effects of attention on motion processing. Visual attention can enhance detection and discrimination of selected visual signals. However, the relationship between attention and motion processing remains contentious: not all studies find that attention increases MAEs. Our meta-analysis reveals several factors that explain superficially discrepant findings.Across studies (37 independent samples, 76 effects) motion adaptation was significantly and substantially enhanced by attention (Cohen’s d=1.12, p<.0001). The effect more than doubled when adapting to translating (vs. expanding or rotating) motion. Other factors affecting the attention-MAE relationship included stimulus size, eccentricity and speed. By considering these behavioural analyses alongside neurophysiological work, we conclude that feature-based (rather than spatial, or object-based) attention is the biggest driver of sensory adaptation.Comparisons between naïve and non-naïve observers, different response paradigms, and assessment of ‘file-drawer effects’ indicate that neither response bias nor publication bias are likely to have significantly inflated the estimated effect of attention.
