Change blindness in a dynamic scene due to endogenous override of exogenous attentional cues
Publication year: 2013

http://www.perceptionweb.com/abstract.cgi?id=p7377
Abstract/Results: ABSTRACT:
Change blindness is a failure to detect changes if the change occurs during a mask or distraction. Without distraction, it is assumed that the visual transients associated with the change will automatically capture attention (exogenous control), leading to detection. However, visual transients are a defining feature of naturalistic dynamic scenes. Are artificial distractions needed to hide changes to a dynamic scene? Do the temporal demands of the scene instead lead to greater endogenous control that may result in viewers missing a change in plain sight? In the present study we pitted endogenous and exogenous factors against each other during a card trick. Complete change blindness was demonstrated even when a salient highlight was inserted coincident with the change. These results indicate strong endogenous control of attention during dynamic scene viewing and its ability to override exogenous influences even when it is to the detriment of accurate scene representation.

Abstract/Results: ABSTRACT:
Visual search is often guided by top-down attentional templates that specify target-defining features. But search can also occur at the level of multiple objects or categories. With adults, we measured the N2pc component, an event-related potential (ERP) marker of attentional target selection in two visual search experiments where targets were defined as either one item (e.g., the letter C), multiple items (e.g., the letters C, F, and X), or categorically (e.g., any letter). Experiment 1 encouraged category-based selection by consistently presenting targets among distractors from a different category (e.g., numbers). Reaction times (RTs) were fastest and the N2pc largest during search for a single item, demonstrating that target selection is most efficient when it is guided by a feature-specific template. There were no RT and N2pc differences between the category-based search task and search for two or three items in Experiment 1, indicating that category-defined templates were used in all three tasks. In Experiment 2, a category-based search strategy was not available because letter targets were now presented among letter distractors. Search efficiency decreased as the number of candidate target letters increased, suggesting that within-category search was based on multiple templates for each target. Results demonstrate that category-based search can operate at early visual stages, and that it is more efficient than within-category search for multiple targets, but less efficient than feature-guided search.

Abstract/Results: ABSTRACT:
Understanding category structure helps us make sense of the world, but little is known about how we use our knowledge about object categories during search. This study used event-related potential (ERP) markers of attentional object selection to investigate differences between search for one or two specific visual objects and category-based search, and to explore how categorical search can overcome working memory limitations. In contrast to most previous ERP studies of visual search which used colored shapes or alphanumeric stimuli, we employed more complex pictorial images of clothing and kitchen utensils. This enabled us to examine attentional selection in a more naturalistic context where participants may try to "find the pants" amongst kitchen utensils (or vice versa). In different blocks, they searched for one single target (e.g., pants), one target that could appear in two different views (e.g., a shirt in one of two possible orientations), two different targets (e.g., either a shoe or a scarf), or a category-defined target (e.g., any of eleven different clothing items). The N2pc component (an ERP marker of attentional object selection) was measured in response to target objects. As expected, this component was largest in the single-target condition where target selection could be based on a perceptual match with a search template. Presenting a single target object from different views had little effect on the N2pc, suggesting that search was object-based rather than view-based. N2pc components were attenuated and delayed in the two-target condition and even more so for category-defined targets, reflecting search efficiency costs when target selection cannot be guided by a single-object template. However, a reliable N2pc was present even during search for one of eleven possible category-defined targets demonstrating that category-based search remained surprisingly efficient. Our results show that category-based attentional guidance is readily available during search for complex naturalistic visual objects.

The role of audience participation and task relevance on change detection during a card trick
Publication year: 2015

Abstract/Results: ABSTRACT:
Magicians utilize many techniques for misdirecting audience attention away from the secret sleight of a trick. One technique is to ask an audience member to participate in a trick either physically by asking them to choose a card or cognitively by having them keep track of a card. While such audience participation is an established part of most magic the cognitive mechanisms by which it operates are unknown. Failure to detect changes to objects while passively viewing magic tricks has been shown to be conditional on the changing feature being irrelevant to the current task. How change blindness operates during interactive tasks is unclear but preliminary evidence suggests that relevance of the changing feature may also play a role (Triesch et al., 2003). The present study created a simple on-line card trick inspired by Triesch et al.’s (2003) that allowed playing cards to be instantaneously replaced without distraction or occlusion as participants were either actively sorting the cards (Doing condition) or watching another person perform the task (Watching conditions). Participants were given one of three sets of instructions. The relevance of the card color to the task increased across the three instructions. During half of the trials a card changed color (but retained its number) as it was moving to the stack. Participants were instructed to immediately report such changes. Analysis of the probability of reporting a change revealed that actively performing the sorting task led to more missed changes than passively watching the same task but only when the changing feature was irrelevant to the sorting task. If the feature was relevant during either the pick-up or put-down action change detection was as good as during the watching block. These results confirm the ability of audience participation to create subtle dynamics of attention and perception during a magic trick and hide otherwise striking changes at the center of attention.

Activation of new attentional templates for real-world objects in visual search

Abstract/Results: ABSTRACT:
Visual search is controlled by representations of target objects (attentional templates). Such templates are often activated in response to verbal descriptions of search targets, but it is unclear whether search can be guided effectively by such verbal cues. We measured ERPs to track the activation of attentional templates for new target objects defined by word cues. On each trial run, a word cue was followed by three search displays that contained the cued target object among three distractors. Targets were detected more slowly in the first display of each trial run, and the N2pc component (an ERP marker of attentional target selection) was attenuated and delayed for the first relative to the two successive presentations of a particular target object, demonstrating limitations in the ability of word cues to activate effective attentional templates. N2pc components to target objects in the first display were strongly affected by differences in object imageability (i.e., the ability of word cues to activate a target-matching visual representation). These differences were no longer present for the second presentation of the same target objects, indicating that a single perceptual encounter is sufficient to activate a precise attentional template. Our results demonstrate the superiority of visual over verbal target specifications in the control of visual search, highlight the fact that verbal descriptions are more effective for some objects than others, and suggest that the attentional templates that guide search for particular real-world target objects are analog visual representations.

http://psycnet.apa.org/journals/xhp/40/4/1283/
Abstract/Results: ABSTRACT:
To compare the speed and efficiency of item-based and category-based attentional control during visual search for real-world objects, we measured N2pc components as electrophysiological markers of attentional target selection. In different blocks, participants searched for 1 or 2 specific target objects or for any object in a target category (items of clothing or kitchen objects). Search displays contained 6 line drawings of different objects, and targets always appeared together with 5 distractors from the other object category. The presence of N2pc components to categorically defined targets demonstrated that category-based search can operate at visuoperceptual processing stages. In contrast to previous findings for letter/digit search (Nako, Wu, & Eimer, 2014), target N2pc components were delayed by 40 ms during category-guided search relative to single-target search. This suggests that for objects and object categories that are less familiar than alphanumerical stimuli, category-guided target selection operates less efficiently than selection that is based on a physical match with an attentional template.

The role of color search templates for real-world target objects

Abstract/Results: ABSTRACT:
During visual search, target representations (attentional templates) control the allocation of attention to template-matching objects. The activation of new attentional templates can be prompted by verbal or pictorial target specifications. We measured the N2pc component of the ERP as a temporal marker of attentional target selection to determine the role of color signals in search templates for real-world search target objects that are set up in response to word or picture cues. On each trial run, a word cue (e.g., “apple”) was followed by three search displays that contained the cued target object among three distractors. The selection of the first target was based on the word cue only, whereas selection of the two subsequent targets could be controlled by templates set up after the first visual presentation of the target (picture cue). In different trial runs, search displays either contained objects in their natural colors or monochromatic objects. These two display types were presented in different blocks (Experiment 1) or in random order within each block (Experiment 2). RTs were faster, and target N2pc components emerged earlier for the second and third display of each trial run relative to the first display, demonstrating that pictures are more effective than word cues in guiding search. N2pc components were triggered more rapidly for targets in the second and third display in trial runs with colored displays. This demonstrates that when visual target attributes are fully specified by picture cues, the additional presence of color signals in target templates facilitates the speed with which attention is allocated to template-matching objects. No such selection benefits for colored targets were found when search templates were set up in response to word cues. Experiment 2 showed that color templates activated by word cues can even impair the attentional selection of noncolored targets. Results provide new insights into the status of color during the guidance of visual search for real-world target objects. Color is a powerful guiding feature when the precise visual properties of these objects are known but seems to be less important when search targets are specified by word cues.

Abstract/Results: ABSTRACT:
An everyday example of change blindness is our difficulty to detect cuts in an edited moving-image. Edit blindness (Smith & Henderson, 2008) is created by adhering to the continuity editing conventions of Hollywood, for example, coinciding a cut with a sudden onset of motion (match-action). In this study, we isolated the roles motion and audio play in limiting awareness of match-action cuts by removing motion before and/or after cuts in existing Hollywood film clips and presenting the clips with or without the original soundtrack whilst participants tried to detect cuts. Removing post-cut motion significantly decreased cut detection time and the probability of missing the cut. By comparison, removing pre-cut motion had no effect suggesting, contrary to the editing literature, that the onset of motion before a cut may not be as critical for creating edit blindness as the motion after a cut. Analysis of eye movements indicated that viewers reoriented less to new content across intact match-action cuts than shots with motion removed. Audio played a surprisingly large part in creating edit blindness with edit blindness mostly disappearing without audio. These results extend film editor intuitions and are discussed in the context of the Attentional Theory of Cinematic Continuity (Smith, 2012a).

Abstract/Results: ABSTRACT:
Filmmakers tell stories by selecting and emphasizing key details of an audiovisual scene through editing, cinematography and sound design. Such edited film sequences instantaneously transport the viewer through space and time in ways that are physically impossible and, due to their divergence from reality should pose problems for viewer comprehension. However, filmmakers believe they have at their disposal a suite of editing techniques, known as the “Continuity Editing Rules” that can minimize viewer awareness of the cuts, create the perception of a continuous scene across sequences of shots and maximize comprehension. In this presentation I will outline the Attentional Theory of Cinematic Continuity (AToCC), a theoretical framework that uses empirical evidence of how we attend to, perceive and comprehend real-world audiovisual scenes to explain how filmmakers have co-opted these natural processes when crafting cinematic stories.
I will argue that in order for us to understand continuity editing we need to understand the role of the viewer in the perceptual construction of a film. What is "flowing" from shot to shot is viewer cognition: what they are attending to, what they are perceiving, and what they are expecting. There is no continuity without a viewer. AToCC acknowledges that the viewer is active, even when sat stationary in a cinema auditorium, and through their gaze they seek out information on the screen, formulate expectations about future events, attend to objects across cuts, and represent minimal details of a scene that are relevant to the narrative. The continuity editing rules use natural attentional cues such as off-screen sounds, conversational turns, motion, gaze cues, and pointing gestures to trigger attentional shifts across cuts. The combination of attentional cues pre-cut, and matching minimal expectations post-cut allow viewer cognition to precede seamlessly from shot to shot, scene to scene, sequence to sequence, and across the entire narrative.

Title: BIAL Grants
Start date: 1994
History:
In 1994 the BIAL Foundation launched a programme of science research grants with the aim of encouraging the research into Man’s physical and mental processes, namely in fields still largely unexplored but which warrant further scientific analysis, as Psychophysiology and Parapsychology.
Since its launch, applications to the BIAL grants have been increasing. Up to now 461 projects have been supported, involving more than 1000 researchers from 27 countries.
The approved applications have benefited from grants in amounts comprised between €5,000 and €50, 000. The amount to be granted is fixed by the Scientific board according to the needs of each project.
The supported projects have originated, until April 2013, in about 600 full papers, 172 out of which were published in indexed international journals with an average impact factor of 3.6 and a substantial number of citations (1665).
Among the BIAL Foundation fellows is worth highlighting the presence of scientists from prestigious universities from the United States, United Kingdom, Australia, Russia, Germany, Japan, France, Canada, and many others.
The BIAL grants are promoted biannually.

Abstract/Results: ABSTRACT:
When watching TV we often have the impression that poorly synchronised audio can “popout”, drawing attention to the speaking actor’s mouth. But how does such capture relate to the levels at which audiovisual asynchrony detection becomes explicit?
Participant eye movements were recorded while they watched an edited thirteen minute TV interview. Unbeknownst to participants, the audiovisual synchrony was manipulated across cuts to create eleven synch conditions between -200ms (audio first) and +200ms (video first). Each synch condition was presented twice with a return to 0ms in between. Conditions gradually increased across the video, +40 to +200ms, then decreased from -40ms to -200ms. Following the initial free-viewing, participants were then instructed to explicitly identify whether the audio was in synch for a 5s clip taken from the same interview under the same eleven synch conditions.
Analysis of participant eye movements during free-viewing revealed a significant bias towards the mouth and away from the eyes at -120ms, +80ms and +120ms asynchrony, levels at which asynchrony was not explicitly detected. These results indicate that asynchronous audiovisual speech captures overt attention even when the degree of asynchrony is subthreshold for explicit awareness and may be used as a measure of implicit asynchrony detection.

Abstract/Results: ABSTRACT:
An everyday example of change blindness is our difficulty to detect cuts in an edited moving-image. Edit blindness (Smith & Henderson, 2008) is created by adhering to the continuity editing conventions of Hollywood, for example, coinciding a cut with a sudden onset of motion (match-action). In this study, we isolated the roles motion and audio play in limiting awareness of match-action cuts by removing motion before and/or after cuts in existing Hollywood film clips and presenting the clips with or without the original soundtrack whilst participants tried to detect cuts. Removing post-cut motion significantly decreased cut detection time and the probability of missing the cut. By comparison, removing pre-cut motion had no effect suggesting, contrary to the editing literature, that the onset of motion before a cut may not be as critical for creating edit blindness as the motion after a cut. Analysis of eye movements indicated that viewers reoriented less to new content across intact match-action cuts than shots with motion removed. Audio played a surprisingly large part in creating edit blindness with edit blindness mostly disappearing without audio. These results extend film editor intuitions and are discussed in the context of the Attentional Theory of Cinematic Continuity (Smith, 2012a).

Category-based guidance of spatial attention during visual search for feature conjunctions
Publication year: 2016

Abstract/Results: ABSTRACT:
The question whether alphanumerical category is involved in the control of attentional target selection during visual search remains a contentious issue. We tested whether category-based attentional mechanisms would guide the allocation of attention under conditions where targets were defined by a combination of alphanumerical category and a basic visual feature, and search displays could contain both targets and partially matching distractor objects. The N2pc component was used as an electrophysio-logical marker of attentional object selection in tasks where target objects were defined by a conjunction of color and category (Experiment 1) or shape and category (Experiment 2). Some search displays contained the target or a nontarget object that matched either the target color/shape or its category among 3 nonmatching distractors. In other displays, the target and a partially matching nontarget object appeared together. N2pc components were elicited not only by targets and by color-or shape-matching nontargets, but also by category-matching nontarget objects, even on trials where a target was present in the same display. On these trials, the summed N2pc components to the 2 types of partially matching nontargets were initially equal in size to the target N2pc, suggesting that attention was allocated simultaneously and independently to all objects with target-matching features during the early phase of attentional processing. Results demonstrate that alphanumerical category is a genuine guiding feature that can operate in parallel with color or shape information to control the deployment of attention during visual search.
