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 ...
متن کاملPersistence in eye movement during visual search.
As any cognitive task, visual search involves a number of underlying processes that cannot be directly observed and measured. In this way, the movement of the eyes certainly represents the most explicit and closest connection we can get to the inner mechanisms governing this cognitive activity. Here we show that the process of eye movement during visual search, consisting of sequences of fixati...
متن کاملHuman frontal eye fields and visual search.
Recent physiological recording studies in monkeys have suggested that the frontal eye fields (FEFs) are involved in visual scene analysis even when eye movement commands are not required. We examined this proposed function of the human frontal eye fields during performance of visual search tasks in which difficulty was matched and eye movements were neither necessary nor required. Magnetic stim...
متن کاملEye 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...
متن کاملPredicting Visual Search Targets via Eye-Tracking Data
The purpose of this work is to train a binary support vector machine to develop a learning mechanism to predict visual search targets and eventually over an unknown set of targets. We used a dataset that contains fixation points of 18 participants searching for a particular image within three types of collages. After plotting the visual patterns of each of the users, we compare the features of ...
