Participants’ eye movements (EMs) and EEG signal were simultaneously recorded to examine foveal and parafoveal processing during sentence reading. All the words in the sentence were manipulated for inter-word spacing (intact spaces vs. spaces replaced by a random letter) and parafoveal preview (identical preview vs. random letter string preview). We observed disruption for unspaced text and invalid preview conditions in both EMs and fixation-related potentials (FRPs). Unspaced and invalid preview conditions received longer reading times than spaced and valid preview conditions. In addition, the FRP data showed that unspaced previews disrupted reading in earlier time windows of analysis, compared to string preview conditions. Moreover, the effect of parafoveal preview was greater for spaced relative to unspaced conditions, in both EMs and FRPs. These findings replicate well-established preview effects, provide novel insight into the neural correlates of reading with and without inter-word spacing and suggest that spatial selection precedes lexical processing. ...

Parafoveal previews and lexical frequency in natural reading: Evidence from eye movements and fixation-related potentials Degno, Federica; Loberg, Otto; Zhang, Chuanli; Zhang, Manman; Donnelly, Nick; Liversedge, Simon P. (American Psychological Association, 2019)Participants’ eye movements and electroencephalogram (EEG) signal were recorded as they read sentences displayed according to the gaze-contingent boundary paradigm.

Fixation-related potentials in naming speed : A combined EEG and eye-tracking study on children with dyslexia Christoforou, Christoforos; Fella, Argyro; Leppänen, Paavo H.T.; Georgiou, George K.; Papadopoulos, Timothy C. (Elsevier, 2021)Objective We combined electroencephalography (EEG) and eye-tracking recordings to examine the underlying factors elicited during the serial Rapid-Automatized Naming (RAN) task that may differentiate between children with ...
Influence of reading skill and word length on fixation-related brain activity in school-aged children during natural reading Loberg, Otto; Hautala, Jarkko; Hämäläinen, Jarmo A.; Leppänen, Paavo H.T. (Elsevier Ltd, 2019)Word length is one of the main determinants of eye movements during reading and has been shown to influence slow readers more strongly than typical readers. The influence of word length on reading in individuals with ...
Burger, Birgitta; Puupponen, Anna; Jantunen, Tommi (European Group for Eye Movement Research, 2018)Both eye tracking and motion capture technologies are nowadays frequently used in human sciences, although both technologies are usually used separately. However, measuring both eye and body movements simultaneously would ...
