The relationship between visual attention and expertise in sports

ObjectivesGiven the prevalence of misperception and failed perception, particularly in attention-demanding team sports, surprisingly few studies have explored whether experts in team sports differ from other athletes and from non-athletes in their basic attention abilities.MethodIn this study, we examined group differences between experts in team handball (n = 40), athletes from non-team sports (n = 40), and novice athletes (n = 40) using a battery of three attention tasks: a functional field of view task, a multiple-object tracking task, and an inattentional blindness task.ResultsPerformance on the three attention tasks was largely independent, with no significant correlations among the tasks. Team sports experts showed no better performance on the basic attention tasks than did athletes from non-teams sports or novice athletes.ConclusionsThe finding that all basic attention tasks are largely independent provides preliminary support for the idea that attentional breadth, tracking performance, and inattentional blindness are distinct attentional processes. Our results demonstrate that sports expertise effects are unrelated to basic differences in attention—expertise does not appear to produce differences in basic attention and basic differences in attention do not appear to predict eventual expertise. Further experiments could focus on the ways in which more specific attentional strategies and processes contribute to sports performance.     

The elephant in the room: collaboration and competition among relief organizations during high-profile disasters

The non-governmental organizations (NGOs) that assume the bulk of emergency care during large-scale disasters in the developing world must expend considerable time and resources to ensure donations to sustain their field operations. This long-standing dilemma for the humanitarian community can create a competitive environment that: Compromises the delivery and quality of services, Allows the effectiveness of operations to be compromised by a lack of cooperation and collaboration, Disrupts the timely and accurate coordination and analysis of outcome measures that are crucial to successful response in the future, and Undermines the long-term capacity of indigenous aid organizations. This article addresses problems and potential solutions for improved coordination and long-term capacity-building of humanitarian aid.     

Natural scene categorization with minimal attention: evidence from negative priming

Research has demonstrated that objects in natural scenes are categorized without the deployment of attention. However, in these types of studies, participants were required to directly respond to peripherally presented scenes, which might lead some participants to move their attention. If this is the case, the above conclusion concerning natural scenes may not be valid. We investigated this issue by using a negative priming (NP) paradigm in which participants did not directly respond to peripheral stimuli. Our results showed NP effect from ignored stimuli in natural scene categorization, but neither in letter discrimination (Experiment 1) nor in line-drawing categorization (Experiment 2). In addition, NP effects were observed even when probe stimuli were words (Experiments 3A and 3B). These findings suggest that people can categorize objects in natural scenes with minimal attention, that this process is specific to natural scenes, and that it is based on the semantic information of the images.     

Influence of semantic consistency and perceptual features on visual attention during scene viewing in toddlers

Conceptual representations of everyday scenes are built in interaction with visual environment and these representations guide our visual attention. Perceptual features and object-scene semantic consistency have been found to attract our attention during scene exploration. The present study examined how visual attention in 24-month-old toddlers is attracted by semantic violations and how perceptual features (i. e. saliency, centre distance, clutter and object size) and linguistic properties (i. e. object label frequency and label length) affect gaze distribution. We compared eye movements of 24-month-old toddlers and adults while exploring everyday scenes which either contained an inconsistent (e.g., soap on a breakfast table) or consistent (e.g., soap in a bathroom) object. Perceptual features such as saliency, centre distance and clutter of the scene affected looking times in the toddler group during the whole viewing time whereas looking times in adults were affected only by centre distance during the early viewing time. Adults looked longer to inconsistent than consistent objects either if the objects had a high or a low saliency. In contrast, toddlers presented semantic consistency effect only when objects were highly salient. Additionally, toddlers with lower vocabulary skills looked longer to inconsistent objects while toddlers with higher vocabulary skills look equally long to both consistent and inconsistent objects. Our results indicate that 24-month-old children use scene context to guide visual attention when exploring the visual environment. However, perceptual features have a stronger influence in eye movement guidance in toddlers than in adults. Our results also indicate that language skills influence cognitive but not perceptual guidance of eye movements during scene perception in toddlers.     

Expert memory: the interaction of stimulus structure,attention, and expertise

This experiment focuses on the three‐way interaction between domain‐relevant structure, attention to domain‐relevant structure, and expertise in their effect on recall for field‐hockey information. It was predicted that experts' recall would decrease with the amount of domain‐relevant structure, but only when they were able to attend to the structure within the stimuli. Novices' recall was not predicted to vary with these factors. The study used a 3 × 2 × 2 mixed‐design with one between‐subjects factor, field hockey expertise (expert and novice), and two within‐subjects factors, domain‐relevant structure (high, moderate and low) and attention to structure (attending and non‐attending). Twenty‐four experts and 24 novices each listened to six audio‐taped scenarios (1 in each of the 6 structure × attention conditions) describing a sequence of field hockey play and recall was tested. The results demonstrated significant main effects for expertise, structure, and attention, and interactions of (a) structure and expertise, and (b) structure and attention. Importantly, the significant structure, attention, and expertise interaction provided the first direct empirical support for the constraint attunement hypothesis (Vicente and Wang, 1998 ) and for that aspect of the template theory (Gobet and Simon, 1996a , b ).

The relative contribution of scene context and target features to visual search in scenes

Many experiments have shown that knowing a targets visual features improves search performance over knowing the target name. Other experiments have shown that scene context can facilitate object search in natural scenes. In this study, we investigated how scene context and target features affect search performance. We examined two possible sources of information from scene context—the scenes gist and the visual details of the scene—and how they potentially interact with target-feature information. Prior to commencing search, participants were shown a scene and a target cue depicting either a picture or the category name (or no-information control). Using eye movement measures, we investigated how the target features and scene context influenced two components of search: early attentional guidance processes and later verification processes involved in the identification of the target. We found that both scene context and target features improved guidance, but that target features also improved speed of target recognition. Furthermore, we found that a scenes visual details played an important role in improving guidance, much more so than did the scenes gist alone.     

Templates for rejection: configuring attention to ignore task-irrelevant features

Theories of attention are compatible with the idea that we can bias attention to avoid selecting objects that have known nontarget features. Although this may underlie several existing phenomena, the explicit guidance of attention away from known nontargets has yet to be demonstrated. Here we show that observers can use feature cues (i.e., color) to bias attention away from nontarget items during visual search. These negative cues were used to quickly instantiate a template for rejection that reliably facilitated search across the cue-to-search stimulus onset asynchronies (SOAs), although negative cues were not as potent as cues that guide attention toward target features. Furthermore, by varying the search set size we show a template for rejection is increasingly effective in facilitating search as scene complexity increases. Our findings demonstrate that knowing what not to look for can be used to configure attention to avoid certain features, complimenting what is known about setting attention to select certain target features.     

Gaze cues influence the allocation of attention in natural scene viewing

In two experiments we examined whether the allocation of attention in natural scene viewing is influenced by the gaze cues (head and eye direction) of an individual appearing in the scene. Each experiment employed a variant of the flicker paradigm in which alternating versions of a scene and a modified version of that scene were separated by a brief blank field. In Experiment 1, participants were able to detect the change made to the scene sooner when an individual appearing in the scene was gazing at the changing object than when the individual was absent, gazing straight ahead, or gazing at a nonchanging object. In addition, participants' ability to detect change deteriorated linearly as the changing object was located progressively further from the line of regard of the gazer. Experiment 2 replicated this change detection advantage of gaze-cued objects in a modified procedure using more critical scenes, a forced-choice change/no-change decision, and accuracy as the dependent variable. These findings establish that in the perception of static natural scenes and in a change detection task, attention is preferentially allocated to objects that are the target of another's social attention.

The Attentional Boost Effect: Transient increases in attention to one task enhance performance in a second task

Recent work on event perception suggests that perceptual processing increases when events change. An important question is how such changes influence the way other information is processed, particularly during dual-task performance. In this study, participants monitored a long series of distractor items for an occasional target as they simultaneously encoded unrelated background scenes. The appearance of an occasional target could have two opposite effects on the secondary task: It could draw attention away from the second task, or, as a change in the ongoing event, it could improve secondary task performance. Results were consistent with the second possibility. Memory for scenes presented simultaneously with the targets was better than memory for scenes that preceded or followed the targets. This effect was observed when the primary detection task involved visual feature oddball detection, auditory oddball detection, and visual color-shape conjunction detection. It was eliminated when the detection task was omitted, and when it required an arbitrary response mapping. The appearance of occasional, task-relevant events appears to trigger a temporal orienting response that facilitates processing of concurrently attended information (Attentional Boost Effect).     

Asymmetries in infants' attention to the presence or absence of features

Three experiments were performed to test whether infants show a bias for detecting the presence of a feature in a stimulus rather than its absence. In the 1st experiment, 24 16-week-old infants were given 3 paired-comparison problems, each of which included a 25-s familiarization phase followed by 2 test trials. Infants were familiarized to 1 member of a set of capital alphabetical letters (E-F; Q-O; B-R). Then they were given a paired-comparison recognition test under 1 of 2 conditions. In the feature-present condition, the familiar letter (e.g., F) was paired with a novel letter containing the addition of a distinguishing element (e.g., E). In the feature-absent condition, infants were presented with a familiar letter (e.g., E) paired with a novel letter in which 1 element was removed (e.g., F). Infants showed a novelty preference to the letter in which the distinguishing feature was present, but there was no preference for novelty in the feature-absent condition. The 2nd experiment showed that infants' fixation to the letter containing the presence of the feature was not due to a simple preference for the letter with the greater number of elements. Finally, to test whether infants' failure to discriminate the absence was due to insufficient encoding time, 36 infants were tested in a 3rd experiment in which familiarization time was varied. After 20 s of familiarization, no evidence of discrimination was observed in either the feature-present or feature-absent condition. After 30 s, however, infants could discriminate the novel letter in the feature-present condition but not in the feature-absent condition. The significance of these results is discussed in terms of theoretical explanations for the development of the feature-presence bias.     

Pay attention! Attention to the primes increases attitude assessment accuracy

We demonstrate that an oft-used indirect attitude assessment technique—the attitude activation paradigm—accurately assesses attitudes only when participants attend to the prime stimuli during the attitude activation task. Attitude activation attitudes toward obviously valenced words (e.g., torture, liberty) were more sensitive to attitude valence and extremity when participants were required to attend to the prime words than when they attended to a competing stimulus. As a result, we observed a significantly stronger correlation between attitude activation attitudes and a direct, self-report attitude measure when participants attended to the primes than when they ignored them. We conclude that failing to require participants to attend to the primes during the attitude activation task results in a flawed measurement, which could lead researchers to underestimate relations between the attitude activation measure and direct, self-report attitude measures.     

Enhanced attention to context: An intervention that increases perceived control in mild depression

People perceive that they have control over events to the extent that the same events do not occur outside of their control, randomly, in the environment or context. Therefore, perceived control should be enhanced if there is a large contrast between one's own control and the control that the context itself seems to exert over events. Given that depression is associated with low perceived control, we tested the hypothesis that enhanced attentional focus to context will increase perceived control in people with and without depression. A total of 106 non-depressed and mildly depressed participants completed a no control zero-contingency task with low and high outcome probability conditions. In the experimental context-focus group, participants were instructed to attend to the context, whereas in the control group, participants were instructed to attend to their thoughts. Irrespective of attentional focus, non-depressed participants displayed illusory control. However, people with mild depression responded strongly to the attention focus manipulation. In the control group, they evidenced low perceived control with classic depressive realism effects. In the experimental group, when asked to focus on the context in which events took place, participants with mild depression displayed enhanced perceived control or illusory control, similar to non-depressed participants. Findings are discussed in relation to whether depression effects on perceived control represent tendencies towards realism or attentional aspects of depressive thoughts.     

Performative and enactive features of psychoanalytic witnessing: The transference as the scene of address

This paper will attempt to broaden the conception of witnessing in analytic work with traumatized patients by extending the idea to incorporate the patient’s developing and varied capacity for witnessing, as well as a witnessing that occurs within the analytic relationship itself. Actions occuring as part of traumatic repetition are understood to represent memory phenomena and are distinguised from dissociated self‐state experience. These experiences are not therapeutically intended to be symbolized, but rather lived‐through with the analyst, thus transforming the patient’s own relation to the experience. I suggest that the scene in which this living‐through takes place is the transference–countertransference matrix, and that it is the analytic encounter that allows traumatic repetition to take on the quality of a communication, an address to another, rather than remain meaningless reproduction. A clinical vignette illustrates the turning of trauma’s imperative for witnessing into an address in the analytic encounter.     

Visual attention in adolescents: Facilitating effects of sport expertise and acute physical exercise

ObjectivesThis study investigated visual attention of adolescent orienteers and physically active adolescents non-practising orienteering both at rest and under acute sub-maximal exercise. It was verified whether the practice of orienteering facilitates the development of visual attentional abilities and whether orienteers, who are used to simultaneously handle physiological and cognitive-attentional loads, may better profit than non-orienteers from the beneficial effects of sub-maximal physical load on processing speed.MethodsBoth the focusing of attention at foveal and parafoveal locations and the orienting of attention at peripheral locations were investigated. In two discriminative reaction time (RT) experiments, a cue of varying size was presented centrally or peripherally and followed by a compound stimulus with local and global target features. The stimulus-onset asynchrony (SOA) varied between a short and a long interval.ResultsIn both experiments, adolescent orienteers and non-practisers showed different patterns of attentional effects. Adolescent orienteers were more similar to young adults in the attentional performance, being better able than non-practisers to perform complex attentional operations involving the intentional zooming of attention in the central visual field and the orienting of the attentional focus in the peripheral visual field. Also, both orienteers and non-orienteers speeded up their performance during exercise, but this facilitation effect was more pronounced for orienteers, who are probably skilled in directing the available resources to task demands.ConclusionsOur results suggest that cognitive expertise represents a key factor in sports that accelerates the development of visual attention and enhances the facilitating effects of physical exercise on attentional performance.     

Physical abuse amplifies attention to threat and increases anxiety in children

Two experiments using event-related potentials (ERPs) examined the extent to which early traumatic experiences affect children's ability to regulate voluntary and involuntary attention to threat. The authors presented physically abused and nonabused comparison children with conflicting auditory and visual emotion cues, posed by children's mothers or a stranger, to examine the effect of emotion, modality, and poser familiarity on attention regulation. Relative to controls, abused children overattended to task-relevant visual and auditory anger cues. They also attended more to task-irrelevant auditory anger cues. Furthermore, the degree of attention allocated to threat statistically mediated the relationship between physical abuse and child-reported anxiety. These findings indicate that extreme emotional experiences may promote vulnerability for anxiety by influencing the development of attention regulation abilities.     

No templates for rejection: a failure to configure attention to ignore task-irrelevant features

ABSTRACT

Knowing the colour of an upcoming target allows one to bias attention towards objects of that colour. It is far less clear whether knowing the colour of an up-coming distractor can allow one to suppress attention to items of that colour. Arita, Carlisle, and Woodman (2012) suggest that people can create a template for rejection. However, the method used in Arita et al. may have allowed people to adopt a strategy of internally generating a positive cue for the target colour or target hemifield. Here we use a method very similar to theirs, but manipulate the display layouts and the number of un-cued colours in ways that should thwart such strategies. Across three experiments, we find a negative cuing benefit only in a very special circumstance that encourages a strategic shift to internally generating a positive cue (the same circumstance used by Arita et al.). We conclude that people are unable to use a negative feature-cue on a trial-by-trial basis to suppress attention to upcoming distractors, and attribute the finding in Arita et al. to a strategic shift rather than a template for rejection.
