Eye movements during search and detection in comparative visual search

Eye movements during search and detection in comparative visual search.

Motivated by the fact that previous visual memory paradigms have imposed encoding and retrieval constraints, the present article presents two experiments that address how observers allocate eye movements in memory and comparison processes in the absence of constraints. A comparative visual search design (Pomplun, Sichelschmidt, et al., 2001) was utilized in which observers searched for a differ...

Eye movements during parallel-serial visual search.

Two experiments (one using O and Q-like stimuli and the other using colored-oriented bars) investigated the oculomotor behavior accompanying parallel-serial visual search. Eye movements were recorded as participants searched for a target in 5- or 17-item displays. Results indicated the presence of parallel-serial search dichotomies and 2:1 ratios of negative to positive slopes in the number of ...

Analysis and models of eye movements in comparative visual search

The manuscript in hand is concerned with the paradigm of comparative visual search. A number of experiments were conducted in which subjects simultaneously viewed two nearly identical images showing sets of simple geometrical objects. Their task was to detect the only mismatch between these images which consisted in either the color or the form of one of the objects. The analysis of eye movemen...

Eye movements during visual search in patients with glaucoma

BACKGROUND Glaucoma has been shown to lead to disability in many daily tasks including visual search. This study aims to determine whether the saccadic eye movements of people with glaucoma differ from those of people with normal vision, and to investigate the association between eye movements and impaired visual search. METHODS Forty patients (mean age: 67 [SD: 9] years) with a range of glau...
