What is the nature of the information that is preserved and combined across saccadic eye movements during the visual analysis of real-world objects? The two experiments reported investigated transsaccadic memory and transsaccadic integration, respectively In the critical condition, participants were presented with one set of contours from an object during one fixation and with a complementary set of contours during the next fixation In Experiment 1, participants could at best inconsistently… 

Types and tokens in transsaccadic object identification: Effects of spatial position and left-right orientation

The results support a model of transsaccadic integration based on two independent representational systems that codes abstract, prestored object types, and the other codes episodic tokens consisting of stimulus properties linked to scene- or configuration-based position markers.

The role of saccade targeting in the transsaccadic integration of object types and tokens.

In the present study, eye movements were monitored in a preview paradigm, and both location-independent and location-dependent preview benefits were observed regardless of the saccade target status of the preview object.

Transsaccadic memory for visual object detail

It is hypothesized that transsaccadic object memory involves the automatic emergence of a visual analog: a high-capacity, non-selective, intemal representation of visual object detail that is strictly limited by attentional and temporal constraints on the process of reading out information from the visual analog.

The Influence of Enantiomorphic Transformation on Transsaccadic Object Integration

Two experiments investigated whether the left-right orientation of an object is retained and integrated across a saccade during object identification. In Experiment 1, participants moved their eyes

Perceptual Grouping of Object Contours Survives Saccades

It is concluded that an intermediate-level description of object shape persists in the visual system across gaze shifts, providing it with a robust basis for balancing efficiency and continuity during scene exploration.

Global Transsaccadic Change Blindness During Scene Perception

The results from two experiments demonstrated a global transsaccadic change-blindness effect, suggesting that point-by-point visual representations are not functional across saccades during complex scene perception.

Accurate visual memory for previously attended objects in natural scenes

The nature of the information retained from previously fixated (and hence attended) objects in natural scenes was investigated. In a saccade-contingent change paradigm, participants successfully

Memory for relational information across eye movements

The results indicate that structural descriptions can be used to represent information in transsaccadic memory in a manner similar to their use in visual short-term memory.

Eye movements and the integration of visual memory and visual perception

The relationship between VSTM consolidation and maintenance and eye movements is explored, to discover how attention selects the information that is to be integrated and whether covert attention was sufficient.



Information integration across saccadic eye movements

Visual memory and the perception of a stable visual environment

The results suggest that perceptual stability and information integration across saccades rely on memory for the relative positions of objects in the environment, rather than on the spatiotopic fusion of visual information from successive fixations.

Integration of Form across Saccadic Eye Movements

It is demonstrated that visual information from previous fixations is preserved in a world-centered representation which is precise enough to support judgements of geometric shape, indicating that visual stability may be normally accomplished by a visual matching strategy in combination with cancellation by an eye-position signal.

Transsaccadic integration of biological motion.

In a transsaccadic integration paradigm, Ss had to detect saccade-contingent changes in a moving point-light walker and anticipated the postsaccadic relative positions of the walker's body parts; the nature of the object representation surviving a saccades was examined and implications for object recognition are highlighted.

Two representational systems in dynamic visual identification.

A theory of dynamic visual identification according to which information is maintained over time both by episodic object representations and long-term memory representations, neither of which necessarily code specific sensory information.

Integrating pictorial information across eye movements.

The results of all six experiments are consistent with a model in which the activation of both the visual features and the name of the picture seen on the first fixation survive the saccade and combine with the information extracted on the second fixation to produce identification and naming of the second picture.

What Is Integrated Across Fixations

A central question of visual perception is how the percept of a stable world emerges from all this chaos.

Role of spatial location in integration of pictorial information across saccades

Identification of a fixated object in a visual display is facilitated by integrating information from a preview of that object in the periphery with information extracted on the subsequent foveal

Effects of Foveal Priming and Extrafoveal Preview on Object Identification

The results of three different experiments suggested that the relation between an object in the fovea on fixation n and an object subsequently brought into the fovea on fixation n + 1 affects the

Roles of object-file review and type priming in visual identification within and across eye fixations.

The results of these experiments support a theory in which the preview benefits observed during visual identification arise from 2 processes, object file review and type priming.
