Processing and memory of central versus peripheral information as a function of reading goals: evidence from eye-movements

The present study examined the effect of reading goals on the processing and memory of central and peripheral textual information. Using eye-tracking methodology, we compared the effect of four common reading goals-entertainment, presentation, studying for a close-ended (multiple-choice) questions test, and studying for an open-ended questions test-on the specific reading time of central and peripheral information and the overall reading time of expository texts. Text memory was tested using multiple-choice questions. Results showed that readers devoted more time to central information than peripheral information during initial reading, regardless of reading goal, but that they adjusted their rereading to the reading goal, with total reading time being longer for central information under some (entertainment and presentation) but not all (open-ended and close-ended questions tests) reading goals. Moreover, readers devoted more time to reading the texts for a study purpose (test or presentation) than for an entertainment purpose, and devoted more time in reading the texts to answer open-ended questions than close-ended questions. Finally, we found that readers remembered more central information than peripheral information under all reading goals. These findings suggest that centrality affects readers' early processing of text whereas reading goals only affect subsequent processing. Interestingly, processing time during reading predicted memory for peripheral information but not for central information.
