(1989) study in which the ball and the server's arm and racquet are the visual focus of attention for skilled tennis players preparing to return a serve. It is interesting to note that the final fixation duration for the near experts was just the opposite, with a longer fixation time on shots they missed than on shots they made. Vickers (1996) reported an experiment in which she recorded the eye movements of elite Canadian women basketball players as they prepared to shoot, and then shot, free throws. A positive answer to this question would provide teachers, coaches, and physical rehabilitation therapists with guidance about how to more effectively design practice and intervention strategies. As you read the following sections, you may find it helpful to refer back to chapter 6, where we discussed various procedures researchers have used to investigate the role of vision in motor control. 2. This question has intrigued scientists for many years, which we can see if we look at the classic and influential work of William James (1890). dual-task procedure an experimental procedure used in the study of attention to determine the amount of attention required to perform an action, or a part of an action; the procedure involves assessing the degree of interference caused by one task when a person is simultaneously performing another task. 3. From choosing to buy a car or a chocolate to a house or a pen, choices are diverse. In terms of the information-processing model in figure 9.1, the basis for this dispute concerns how we select information from the environmental context to process in the first stage. Another aspect of attention occurs when you need to visually select and attend to specific features of the environmental context before actually carrying out an action. You will find that researchers who study visual selective attention have used these same procedures. The racquet and the arm are the primary sources to visually search for the anticipatory cues needed to prepare the return. Performance deteriorates because the skilled individual reverts to an earlier, less automatic form of movement control. Computerized simulation as a means of improving anticipation strategies and training in the use of the return in tennis. The problem with a generalized training approach to the improvement of visual attention is that it ignores the general finding that experts recognize specific patterns in their activity more readily than do novices. Describe how you would help people acquire the capability to perform this multiple-activity skill beginning with their not being able to do all the activities simultaneously. Attention and Effort. Conversely, people have difficulty performing two different hand responses simultaneously because they both demand resources from the same structure. (b) For each type, describe a motor skill situation in which that focus option would be preferred. Without detection of these conditions a person would not have the information needed to prepare and initiate movement to reach for and grasp a cup, or any stationary object. The results of these two studies have been replicated in several other studies (see Falkmer & Gregerson, 2005, for a review of this research). This relationship is often referred to as the Yerkes-Dodson law, which is named after two Harvard researchers who initially described this relationship in 1908 by investigating the relationship between stress and learning (Yerkes & Dodson, 1908; see also Brothen, 2012). You are attending to your conversation with another person. A study of cell phone records of 699 people who had been involved in motor-vehicle accidents reported that 24 percent were using their cell phones within the 10 min period before the accident (Redelmeier & Tibshirani, 1997). ), The selection of features of interest occurs when a person focuses the attentional spotlight on the master map of all features. A., Stone, The intention to grasp an object directed participants' visual search to the spatial orientation of an object, whereas the intention to point to the object did not. For example, when you reach for a cup to drink the coffee in it, you visually note where the cup is and how full it is before you reach to pick it up. Prehension while walking. If your institution subscribes to this resource, and you don't have a MyAccess Profile, please contact your library's reference desk for information on how to gain access to this resource from off-campus. In a study that was done many years ago, but continues to be preferred as a demonstration of this role for vision, Mourant and Rockwell (1972) had novice and experienced drivers drive a 2.1 mile neighborhood route and a 4.3 mile freeway route. Motor Learning and Control: Concepts and Applications, 11e, (required - use a semicolon to separate multiple addresses). Information was thought to be excluded from the central nervous system When there is little traffic, driving does not demand many resources from any of the three different sources. Some tasks might be relatively automatic in that they make few demands in te. Do we visually select relevant environmental cues according to our action intentions and goals, or do we visually attend to environmental cues because of their distinctiveness or meaningfulness in the situation? Evidence to support the idea that novices perform better under skill-focused instructions and experts perform better when distracted from focusing on the skill itself has been provided for the skills of golf putting (Beilock et al., 2004) and soccer dribbling (Beilock et al., 2002; Ford et al., 2005). Although researchers have proposed several theories to account for the characteristics of how we select certain cues in the environment and ignore others (see Neumann, 1996, for a review of these theories), one of the more popular theories is the feature integration theory proposed by Treisman in the 1980s (e.g., Treisman 1988; Treisman & Gelade 1980; see also Chan & Hayward, 2009). F., & Hagemann, (1996). Give an example. Bourdin, The authors indicate that these results should encourage strength and conditioning professionals as well as coaches to provide instructions that focus an athlete's attention externally rather than internally. Each of these activities requires attention and must be carried out in the course of a few seconds. A CLOSER LOOK The "Quiet Eye"A Strategic Part of the Visual Search Process for Performing Motor Skills, Research by Joan Vickers and her colleagues discovered an important characteristic of visual search that is associated with successful motor skill performance. gained acceptance by researchers today is the limited capacity theory by Kahneman (1973). These events can be visual or auditory. We briefly considered the attention-capacity demands of a skill in the discussion of the evaluation of the task demands component of Kahneman's model of attention. As a result of these two factors, eye movement recordings cannot provide a complete picture of the environmental features to which the person is directing visual attention. Abernethy indicated that another essential source of information to detect is the kinematics of an opponent's action, which specify what he or she is going to do next. As a result, to maintain safe driving, the person must reduce the resource demand of the conversation activity. System 1 . This would mean that peripheral vision was the source of picking up the relevant information. Golfers tend to associate visual attention with head position, which means they consider a change in visual attention to be related to a change in head movement. This type of relationship indicates that arousal levels that are either too low or too high will result in poor performance. To read the autobiography of Daniel Kahneman (who developed the attention theory discussed in this chapter) as written for the Nobel Prize ceremony in 2002, go to http://nobelprize.org/. If the person's arousal level is too low or too high, he or she has a smaller available attention capacity than he or she would if the arousal level were in an optimal range. People will be more likely to be distracted while preparing to perform, or performing, a motor skill when events occur in the performance environment that are not usually present in this environment. Executive attention, working memory capacity, and a two-factor theory of cognitive control. Allocation policy: depends on how much attention is divided between each task. An important historical root of capacity theory lies in the human . An experiment by Helsen and Pauwels (1990) provides a good demonstration of visual search patterns used by experienced and inexperienced male players to determine these actions. A., & Martinez, For example, in a comparison of driving performance while conversing on a cell phone, conversing with a passenger, and having no conversation, researchers at the University of Utah found that when drivers engaged in cell phone conversations, they increased their driving errors (Drews, Pasupathi, & Strayer, 2008). For example, Bekkering and Neggers (2002) demonstrated that the focus of initial eye movements differed when participants in their experiment were told to point to or grasp an object. He raised this same question more than a century ago and offered as an answer that the directing of attention to the "remote effects" (i.e., outcome of a movement, or movement effects) would lead to better performance than attention to the "close effects" (i.e., the movements). However, this approach is rooted in two suppositions: 1) Attention is a limited capacity resource, and 2) Attentional capacity can be distributed among sensory modalities. The feature integration theory of visual selective attention is one of the more popular explanations of how people visually select and attend to certain cues in the performance environment and ignore others. Wickens proposed what has become the most popular of these theories. D. L., & Drews, (2004). Their results indicated that the supplementary motor area (SMA) and putamen/globus pallidus regions are more involved with automaticity than when each of the two tasks demand attention, in which case the prefrontal regions are more active. Purpose. The research evidence for the "quiet eye" is based on the use of eye movement recording technology, which was discussed in chapter 6. may be performed consciously or nonconsciously (eg breathing) involves a limitation in the capacity (or resources) available to handle info. Depending on the purpose of the experiment, the performer may or may not need to maintain consistent primary-task performance, when performing that task alone compared to performing it simultaneously with the secondary task. This div only appears when the trigger link is hovered over. In fact, in the late nineteenth century, a French physiologist named Jacques Loeb (1890) showed that the maximum amount of pressure that a person can exert on a hand dynamometer actually decreases when the person is engaged in mental work. limited amount of resources available to conduct tasks (Kahneman, 1973) multiple resources, only one cognitive process can occur at a time (Pashler) . a metabolic expenditure that occurs inside the brain . We typically will "involuntarily" direct our attention to (or be distracted by) at least two types of characteristics of events in our environment, even though we may be attending to something else at the time. Head movement also preceded the initiation of reaching movements. Around the same time, William Wundt, generally acknowledged as the "father of experimental psychology," investigated the concept of attention at the University of Leipzig in Germany. For example, golfers fixate on the ball, free-throw shooters in basketball fixate on the rim of the basket, walkers fixate on stepping stones along a pathway, etc. Both situations are important for the performance of motor skills. Results from two experiments by Goulet, Bard, and Fleury (1989) demonstrate how critical visual search strategies are to preparing to return tennis serves. In terms of attention processes involved in motor skill performance, the "quiet eye" characteristic of visual search demonstrates the importance of the visual focus of attention.*. If, as we just discussed, it is best for people to narrow their attentional focus while performing certain skills, a relevant question concerns the specific location of the attentional focus. Theories emphasizing attentional resource limits propose that we can perform several tasks simultaneously, as long as the resource capacity limits of the system are not exceeded. In each of these situations, it is clearly to the player's advantage to detect the information needed as early as possible in order to prepare and initiate the appropriate action. In Kahneman's model (see figure 9.3), the single source of our mental resources from which we derive cognitive effort is presented as a "central pool" of resources (i.e., available capacity) that has a flexible capacity. Interestingly, all five players did not use the same visual search strategies. We observe and attend to the environment in which we move to detect features that help us determine what skill to perform and how to perform it. However, researchers who have investigated this issue, in either car simulators or simulated driving situations in laboratories, report evidence that indicates an attention-related basis for driving accidents. This attention-directing process is known as attentional focus. Several examples of effective visual search training programs have been reported (e.g., Abernethy, Wood, & Parks, 1999; Causer, Holmes, & Williams, 2011; Farrow et al., 1998; Haskins, 1965; Singer et al., 1994; Vera et al., 2008; Vickers, 2007; Wilson, Causer, & Vickers, 2015). Finally, Williams and Davids (1998) reported a comprehensive investigation of visual selective attention and search strategies of experienced and less-experienced soccer players in three-on-three and one-on-one situations. Notice also that within this box is the word "Arousal." But, some problems require more effort to solve; they require effortful mental activities that are also influenced by experience and practice. What Makes Certain Features More Distinctive than Others? Each resource pool is specific to a component of performing skills. The influence of mental and motor load on handwriting movements in Parkinsonian patients. A CLOSER LOOK An Attention-Capacity Explanation of the Arousal-Performance Relationship. Because beginners tend to consciously control many of the details associated with performance, she believes that a skill-focused attention is appropriate early in learning. It is also thought to be the basis for what is commonly referred to as choking under pressure (Beilock, 2010; Beilock & Carr, 2001). (See Wolfe, 2014 and Hershler & Hochstein, 2005, for an extended discussion of feature integration theory and factors that influence the "pop out" effect.). R. F., & Bernbunan-Fich, However, their head movement to shift visual attention from one location to another is generally initiated by eye movement. Central Capacity Theory. The reason relates to the meaningfulness of your name to you. . Expertise differences in preparing to return a tennis serve: A visual information processing approach. For example, if one task requires a hand response and one requires a vocal response, a person should have little difficulty performing them simultaneously, because they do not demand attention from the same resource structure. Vickers interpreted this finding as evidence that the near experts did not fixate long enough just prior to the release of the ball for the shots they made or missed to allow them to attain the shooting percentage of the expert. An example of one of these types of characteristics is that the event is novel for the situation in which it occurs. Thus, the eyes' searching of the environment to determine the location and characteristics of the object started a chain of events to allow the participants to grasp the object successfully. J. J. According to this model, attention is a single resource that can be divided among different tasks in different amounts. ATTENTION (continued) Capacity Models . In effect then, this minimal essential information "pops out" for the skilled player and directs the player's visual attention as he or she prepares an appropriate action to respond to his or her opponent's action. central-resource theories of attention attention-capacity theories that propose one central source of attentional resources for which all activities requiring attention compete. A classic example of this characteristic is known as the cocktail party phenomenon, which was first described in the 1950s (Cherry, 1953). To experience several different types of visual search tasks often used in laboratories, go to www.gocognitive.net/demo/visual-search. It is interesting to note, however, that studies by Green and Bavelier (2003, 2006) found that highly experienced players of action video games exhibited better visual selective attention capabilities than nonplayers. selective attention in the study of attention as it relates to human learning and performance, the term used to refer to the detection and selection of performance-related information in the performance environment. Shipp, Skill differences in visual anticipation of type of throw in team-handball penalties. Research evidence has shown that peripheral vision is involved in visual attention in motor skill performance (see Bard, Fleury, & Goulet, 1994 for a brief review of this research). Brauer, V. (1998). Kahneman included this word to indicate that the arousal level of the person significantly influences that person's available attention capacity at any given time. Neural correlates of learning to attend. In this competitive situation, the person's coach is very meaningful to the athlete. Some of the most influential theories treat the selectivity of attention as resulting from limitations in the brain's capacity to process the complex . Kahneman, D. (1973). Visual search is an important part of this process. A generic information-processing model on which filter theories of attention were based. Neural correlates of visual-spatial attention in electrocoticographic signals in humans. By influencing these processes, the visual system enables a person to prepare, initiate, and execute the movements of an action that conform to the specific requirements of the performance context. Each skill provided evidence that effective visual search strategies are distinctly specific to the requirements of the action and to the skill level of the performer. Comparisons of conversations on cell phones and conversations with car passengers have consistently found that cell phone conversations are related to more driving errors than are passenger conversations. Walk 14 m at a self-selected speed (single task: free walking), Walk while transferring as many coins as possible from one pocket to another on their opposite side (motor secondary task: manual object manipulation), Walk while counting backward aloud by threes from a three-digit number (cognitive secondary task: subtraction), a greater amount of deterioration in their walking gait characteristics when they had to simultaneously perform a manual object-manipulation task and cognitive task involving subtraction than comparably aged people who did not have PD, a slower rate of performing a manual object-manipulation task and a cognitive task involving subtraction when they had to perform these tasks while walking than when they performed them while standing.
