Article
Aphantasia describes the experience of individuals who self-report a lack of voluntary visual imagery. It is not yet known whether individuals with aphantasia show deficits in cognitive and neuropsychological tasks thought to relate to aspects of visual imagery, including Spatial Span, One Touch Stocking of Cambridge, Pattern Recognition Memory, Ve...

Using the prime–probe comparison paradigm, Jacob, Breitmeyer, and Treviño (2013) demonstrated that information processing in visual short-term memory (VSTM) proceeds through three stages: sensory visible persistence (SVP), nonvisible informational persistence (NIP), and visual working memory (VWM). To investigate the effect of increasing the memory...

To investigate the role of attention in the time course of visual working memory, a memory scanning experiment was conducted with three conditions: control, neutral cue and spatial cue. On each trial, a memory array of 4 items (simple geometric shapes) preceded a probe item at varying inter-stimulus intervals (ISIs). In cued conditions, either a ne...

What is the role of top-down attentional modulation in consciously accessing working memory (WM) content? In influential WM models, information can exist in different states, determined by allocation of attention; placing the original memory representation in the center of focused attention gives rise to conscious access. Here we discuss various li...
Poster
Previous studies have shown that when working memory (WM) has reached its processing limit due to maintaining a substantial amount of information, its cognitive resources are depleted for subsequent cognitive functions, such as for selective attention (SA) (de Fockert et al., 2001; Downing, 2000). Using a dual-task paradigm combining a change-detec...

We compared scanning of working memory for simple geometric shapes in cued (location, neutral) and non-cued (control) conditions to investigate the role of attention in the time course of visual working memory. A memory array of 4 items preceded a probe item at varying inter-stimulus intervals (ISIs), ranging from 520 to 5000ms, in the control cond...
Poster
Priming and comparison tasks were used to assess the time course of iconic and post-iconic processing in visual short-term memory (VSTM) for form and/or color features. A prime preceded a probe at varying stimulus onset asynchronies (SOAs); observers reported the probe's form or color feature in the priming task, and whether or not the probe matche...
Conference Paper
Prior studies of information transfer rates from brief iconic to durable post-iconic levels of processing differ significantly. Estimates range from roughly 10 ms/letter to 50 ms/letter consolidation rate, indicating that initial readout of information from iconic to post-iconic levels of processing may not be identical to subsequent processes of c...

We compared visual priming and comparison tasks to assess information processing of a stimulus during the first 2 s after its onset. In both tasks, a 13-ms prime was followed at varying SOAs by a 40-ms probe. In the priming task, observers identified the probe as rapidly and accurately as possible; in the comparison task, observers determined as ra...
Article
Flanker congruency effects were measured in a masked flanker task to assess the properties of spatial attention during conscious and nonconscious processing of form, color, and conjunctions of these features. We found that (1) consciously and nonconsciously processed colored shape distractors (i.e., flankers) produce flanker congruency effects; (2)...
Poster
Visual information first enters visual short-term memory through a brief sensory register (iconic memory) and is then transferred to a more durable visual working memory (VWM) store. Previous masking studies (e.g., Michaels & Turvey, 1979) indicate that transfer of items from iconic memory to VWM requires attention. However, it is unclear whether t...
Article
Using metacontrast masking we examined the temporal dynamics of surface completion in object vision. By varying the stimulus onset asynchrony between the target object and the flanking mask(s), we obtained estimates of the time required for the entire surface contrast to fill out within the area delimited by the contours/edges of the target. The es...
Article
We examine metacontrast masking with texture-defined second-order stimuli. Our results reveal that (1) the monotonic type A as well as the nonmonotonic (U-shaped) type B metacontrast effect, which has been extensively examined with first-order luminance-defined stimuli, can be obtained with texture-defined second-order stimuli; and (2) while variat...
Article
What is known about contour and surface feature processing in the primate visual system applies mainly to first-order stimuli, such as objects defined by wavelength- or luminance-contrast differences. It is unclear whether the same processes and their properties apply to perception of second-order stimuli, such as shapes created in random-dot stere...
Article
In two experiments we used bilateral and unilateral backward masking to investigate the time course of a a rectangular target's surface completion. Our results show in both the bilateral and unilateral masking conditions that surface completion proceeds as a “filling out” from the interior middle region of the target toward its edges. Both masking...
Article
We investigate the processing of two features, form or else color, stored in visual short-term memories (VSTMs) in a feature priming task and a feature comparison task. In both tasks a brief prime is followed by a probe at stimulus onset asynchronies (SOAs) ranging from 63 to 1920 ms. The prime's and probe's features could either be congruent or el...

Psychophysical and neurophysiological experiments have demonstrated that at the implicit (i.e. nonconscious) level first-order luminance-defined contours are processed on average 30-60 ms before surface information. Here, figure-ground segmentation processes establish contours that are later filled in with surface (e.g. wavelength and brightness) i...
