The combined effect of context and case alternation on migration
- 31 Downloads
Previous studies have demonstrated the occurrence of perceptual interactions when words are presented simultaneously in a visual display. The interactions, or migrations, consist of the formation of new words from letters in the display. Contextual information can increase the probability of migration. A difference in visual form between the words does not affect the occurrence of migrations.
Two experiments are reported that manipulate context and visual form. Both between-word case alternation and within-word case alternation were used. Neither of these two forms of case alternation affected the occurrence of migrations or the interaction of context with migration, although within-word case alternation reduced the accuracy of word identification.
