Hemispheric Asymmetry in Imagery Processing That Links to Language: an Event-related Potential Study

106 Cognitive Neuroscience Society replicate the Þ nding that high-frequency words can elicit an N250 priming effect using this paradigm, and further show that the presence and size of this effect is dependent upon the order of stimulus presentation. Both high-frequency and low-frequency N250 priming effects were larger when the words were presented in the Þ rst block. High-frequency words only elicited a signiÞ cant priming effect from 200-300ms when they preceded the low-frequency block. These Þ ndings suggest that the effects of word frequency on N250 masked priming effects are highly sensitive to experimental context. Both highand low-frequency words are inß uenced by presentation order and N250 priming effects may be especially sensitive to presentation parameters when participants read extremely high-frequency words.
