“…Our data suggest that a delay as short as 45 ms suffices to break the 25 element mask into smaller masks. Similar fast grouping effects were found previously (Herzog, Fahle, & Koch, 2001;Herzog et al, 2008;.…”

In visual backward masking, the perception of a target is influenced by a trailing mask. Masking is usually explained by local interactions between the target and the mask representations. However, recently it has been shown that the global spatial layout of the mask rather than its local structure determines masking strength (Hermens & Herzog, 2007). Here, we varied the mask layout by spatial, luminance, and temporal cues. We presented a vernier target followed by a mask with 25 elements. Performance deteriorated when the length of the two mask elements neighboring the target vernier was doubled. However, when the length of every second mask element was doubled, performance improved. When the luminance of the neighboring elements was doubled, performance also deteriorated but no improvement in performance was observed when every second element had a double luminance. For temporal manipulations, a complex nonmonotonic masking function was observed. Hence, changes in the mask layout by spatial, luminance, and temporal cues lead to highly different results.

“…Our data suggest that a delay as short as 60 ms suffices to break the grouping between the simultaneous and the temporal masks. Similar fast grouping effects were found for elements of a backward mask appearing in different orders (Herzog, Koch, & Fahle, 2001), for different masks presented one after another (Herzog et al, 2008), and in sequences of verniers with different offsets (Hermens et al, in press).…”

“…These grouping processes have been identified empirically by the impact that grouping has on the visibility of a briefly presented target stimulus when presented with either a temporal or a simultaneous mask (e.g. Hermens et al, in press; Herzog, Fahle, & Koch, 2001; Herzog, Schmonsees, Boesenberg, Mertins, & Fahle, 2008). The current experiments add to the evidence that grouping might be an early visual process by exploring how grouping of the elements of a temporal and a simultaneous mask determines the visibility of a briefly presented target element.…”

Simultaneous and temporal masking are two frequently used techniques in psychology and vision science. While there are many studies and theories related to each masking technique, there are no systematic investigations of their mutual relationship, even though both techniques are often applied together. Here, we show that temporal masking can both undo and enhance the deteriorating effects of simultaneous masking depending on the stimulus onset asynchrony between the simultaneous and temporal mask. For the task and stimuli used in this study, temporal masking was largely unaffected by the properties of the simultaneous mask. In contrast, simultaneous masking seems to depend strongly on spatial grouping and was strongly affected by the properties of the temporal mask. These findings help to identify the nature of both temporal and simultaneous masking and promote understanding of the role of spatial and temporal grouping in visual perception.

Visual backward masking is a versatile tool for understanding principles and limitations of visual information processing in the human brain. However, the mechanisms underlying masking are still poorly understood. In the current contribution, the authors show that a structurally simple mathematical model can explain many spatial and temporal effects in visual masking, such as spatial layout effects on pattern masking and B-type masking. Specifically, the authors show that lateral excitation and inhibition on different length scales, in combination with the typical time scales, are capable of producing a rich, dynamic behavior that explains this multitude of masking phenomena in a single, biophysically motivated model.
