“…In other words, object files should have a limited lifetime that corresponds to the interval that still allows for perceiving an object as constant. In Kahneman et al's (1992) original study, the delay between two presentations of the critical stimuli was in the range of milliseconds, but later studies found that object files can persist as long as 8 sec (Noles, Scholl, & Mitroff, 2005). It may be interesting to note that these rather long lifetimes were observed under conditions in which the interval between two presentations was filled by other visual events-events that served to bridge the two presentations by implying some kind of change (such as the rotation of the display, which contained placeholders of the actual stimuli).…”

In two experiments, we studied the temporal dynamics of feature integration with auditory (Experiment 1) and audiovisual (Experiment 2) stimuli and manual responses. Consistent with previous observations, performance was better when the second of two consecutive stimuli shared all or none of the features of the first, rather than when only one of the features overlapped. Comparable partial-overlap costs were obtained for combinations of stimulus features and responses. These effects decreased systematically with increasing time between the two stimulus-and-response events, and the decreased rate was comparable for unimodal and multimodal bindings. General effect size reflected the degree of task relevance of the dimension or modality of the respective feature, but the effects of relevance and of temporal delay did not interact. This suggests that the processing of stimuli on task-relevant sensory modalities and feature dimensions is facilitated by task-specific attentional sets, whereas the temporal dynamics might reflect that bindings "decay" or become more difficult to access over time.

“…In the modified version (see Noles et al, 2005), participants are typically presented with two simple objects (e.g., outlined frames). Information (e.g., a letter or picture) is briefly presented in each of the frames during a ''preview'' display (see Figure 1A).…”

An important task of perceptual processing is to parse incoming information into distinct units and to keep track of those units over time as the same, persisting representations. Within the study of visual perception, maintaining such persisting object representations is helped by ''object files''*episodic representations that store (and update) information about objects' properties and track objects over time and motion via spatiotemporal information. Although object files are typically discussed as visual, here we demonstrate that objectÁfile correspondence can be computed across sensory modalities. An object file can be initially formed with visual input and later accessed with corresponding auditory information, suggesting that object files may be able to operate at a multimodal level of perceptual processing.Perception is a complicated process with impressive feats seemingly accomplished with ease. For example, immense amounts of undifferentiated information are smoothly transformed into meaningful units; photons of

“…When the frames stop moving, a single target stimulus is presented within one of the frames. The participant's task is usually to name the target, although in some experiments participants indicate whether the target matches one of the preview stimuli (e.g., Noles & Scholl, 2005; Noles, Scholl, & Mitroff, 2005). …”

Episodic representation of diagnostic and nondiagnostic object colour

In three experiments, we investigated transsaccadic object file representations. In each experiment, participants moved their eyes from a central fixation cross to a saccade target located between two peripheral objects. During the saccade, this preview display was replaced with a target display containing a single object to be named. On trials in which the target identity matched one of the preview objects, its color either matched or did not match the previewed object color. The results indicated that color changes disrupt perceptual continuity, but only for the class of objects for which color is diagnostic of object identity. When the color is not integral to identifying an object (for example, when the object is a letter or an object without a characteristic color), object continuity is preserved regardless of changes to the object's color. These results suggest that object features that are important for defining the object are incorporated into its episodic representation. Furthermore, the results are consistent with previous work showing that the quality of a feature's representation determines its importance in preserving continuity.
