The saccadic spike artifact in MEG
Christine Carl,Alper Açık,Peter König,Peter König,Andreas K. Engel,Joerg F. Hipp,Joerg F. Hipp +6 more
TL;DR: The results show that the SF in MEG closely resembles neuronal activity in frontal and temporal sensors, and the source configurations of the SF were comparable for regular and miniature saccades.
Journal ArticleDOI
Developmental Changes in Natural Viewing Behavior: Bottom-Up and Top-Down Differences between Children, Young Adults and Older Adults.
TL;DR: The results indicate that, with age, bottom-up fixation selection loses strength and/or the role of top-down processes becomes more important and older adults who increase their feature-related viewing by being more explorative make use of this low-level information and perform better in the task.
Journal ArticleDOI
Effects of luminance contrast and its modifications on fixation behavior during free viewing of images from different categories
TL;DR: An inverse relationship between modification effects and higher-level, phase-dependent image features is revealed and it is suggested that high- and mid-level features--such as edges, symmetries, and recursive patterns--guide attention if present, but if the scene lacks such diagnostic properties, low- level features prevail.

TL;DR: A dataset of free-viewing eye-movement recordings that contains more than 2.7 million fixation locations from 949 observers on more than 1000 images from different categories presents a strong opportunity for evaluating and comparing computational models of overt attention and for thoroughly quantifying strategies of viewing behavior.
