Summary
This study found no gap effect in reading, even with disappearing text. However, word frequency and length still impact eye movements and reading control.
Area of Science:
- Cognitive Psychology
- Psycholinguistics
- Ophthalmology
Background:
- Reading involves complex eye movements and visual processing.
- The gap effect, a phenomenon in speech perception, has been hypothesized to occur in reading.
- Understanding oculomotor control is crucial for reading comprehension.
Purpose of the Study:
- To investigate the presence of a gap effect during reading.
- To determine the influence of linguistic and visual factors on eye movement control.
- To explore how text modifications affect reading behavior.
Main Methods:
- Eye movements were tracked while participants read sentences under normal, masked, and disappearing text conditions.
- Global and local analyses of oculomotor data were performed.
- Linguistic variables (word frequency, word length) and visual factors were manipulated.
Main Results:
- No evidence for a gap effect was found in reading, even with disappearing text.
- Cognitive/lexical processes significantly influence eye movement control.
- Visual factors, such as persistent visual objects, can cause refixations.
- Word frequency and length effects persisted even when text was masked or disappeared.
Conclusions:
- The gap effect does not appear to be a factor in reading.
- Oculomotor control during reading is a dynamic process influenced by both cognitive and visual information.
- Reading behavior is sensitive to word properties like frequency and length, regardless of text stability.
