Many countries, and some cities and states in the United States, have passed laws that prohibit cell phone use while driving. When you need to maneuver around people and objects as you walk along a corridor, you look to see where they are, what direction they are moving in, and how fast they are going. The most prominent among the first theories addressing attention limitations1 was the filter theory of attention, sometimes referred to as the bottleneck theory. 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.*. As you will see here, and in the remaining chapters in this book, the concept of attention is involved in important ways in the learning and performance of motor skills. 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. To determine whether to shoot, pass, or dribble in soccer, the player must use visual search that is different from that involved in the situations described above. The following research examples illustrate how researchers have investigated a variety of sports and everyday skills, and provide a sense of what we currently know about the characteristics of visual search processes related to the performance of open and closed motor skills. J., Garganta, 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. Sometimes, these intentions are self-directed, which means the person has personally decided to direct attention to a certain aspect of the situation. theory of attention and perceptual processing a) sometimes process all parts of a scene in parallel (at the same time) . Research support for this view has come from several studies that involved a variety of techniques, including dual-task probe reaction times and EMG assessment (see Wulf, 2013; Zachry, Wulf, Mercer, & Bezodis, 2005; and Gray, 2011, for brief reviews of these studies). Since the earliest days of investigating human behavior, scholars have had a keen interest in the study of attention. An important historical root of capacity theory lies in the human . Why did you do this? This means that rather than considering the attention-capacity demand of an activity in terms of "yes, it demands capacity," or "no, it doesn't demand capacity," the continuum view considers automaticity as related to demanding varying amounts of attention capacity. multiple resource theory. As illustrated in figure 9.4, during the ritual phase, the expert players focused mainly on the head and the shoulder/trunk complex, where general body position cues could be found. As you read in chapter 6, eye movement recordings track the location of central vision while people observe a scene. I. C., Teasdale, These strategies are often acquired without specific training and without the person's conscious awareness of the strategies they use. Discuss two different dual-task techniques that researchers use to assess the attention demands of performing a motor skill. Two results are especially noteworthy. Concept: Preparation for and performance of motor skills are influenced by our limited capacity to select and attend to information. He then argued that mental effort reflects variations in processing . For the successful performance of a closed skill the final gaze fixation, just prior to performing the skill, is typically located on the goal object in the performance environment. Strayer, Is it preferable to focus attention on one's own movements (internal focus) or on the effects of one's own movements (external focus)? Central Capacity Theory. We allocate attention to the most meaningful features. visual search the process of directing visual attention to locate relevant information in the environment that will enable a person to determine how to prepare and perform a skill in a specific situation. Daniel Kahneman took a different approach to describing attention, by describing its division, rather than selection . The amount of available resources (i.e., attention capacity) can increase or decrease according to the general arousal level of the performer. M. J., & Raymond, The general purpose of experiments using this technique is to determine the attention demands and characteristics of the simultaneous performance of two different tasks. For example, a football quarterback may look to decide if the primary receiver is open; if not, he must find an alternate receiver. These four characteristics indicate the "need for an optimal focus on one location or object prior to the final execution of the skill" (McPherson & Vickers, 2004, p. 279). According to both Kahneman's and Logan's perspectives, a complex motor skill could involve activities that require a range of attention demands. During the windup, experts fixated on the release point, whereas novices tended to shift fixations from the release point to the pitcher's head. Fluctuation Patterns of Autonomic Arousal Predict Mental Arithmetic Performance. On the other hand, because highly skilled individuals have proceduralized most aspects of performance and execute skills automatically with little conscious attentional monitoring, she believes that an environmental focus of attention is better in the later stages of learning. A generic information-processing model on which filter theories of attention were based. This result indicates that more experienced drivers require less time to detect and process the information obtained from a fixation, which gives them an advantage in determining the appropriate driving action to take in the situation. In the following discussion, you will be introduced to the concept of attention as it relates to the types of motor skill performance situations we have just considered. A renaissance in attention research occurred, however, when the practical requirements of World War II included the need to understand human performance in a variety of military skills. Visual search picks up critical cues that influence three parts of the action control process: action selection, constraining of the selected action (i.e., determining the specific movement features for performing the action), and timing of action initiation. People's ability to maneuver through environments like these indicates that they have detected relevant cues and used them in advance to avoid collisions. engagement in the perceptual, cognitive, and motor activities associated with performing skills. Illustration showing where expert tennis players in the Goulet, Bard, and Fleury experiment were looking during the three phases of a tennis serve. Finally, more recent attention theories have moved away from the concept of a central capacity limit to one that emphasizes the selection and integration of information and activities associated with the various functional aspects of human performance, such as those depicted in figure 9.1. van Gemmert, Lab 9 in the Online Learning Center Lab Manual provides an opportunity for you to experience the dual-task procedure to assess attention-capacity demands of two tasks performed simultaneously. Thus, attention is defined within this model as the process of allocating cognitive capacity to the various incoming sensory demands. Within that time period, there appears to be a critical time window for visually picking up critical cues predicting where the shuttle will land. Results based on subjects' eye-movement characteristics while watching an actual soccer game showed that the experienced players fixated more on the positions and movements of other players, in addition to the ball and the ball handler. System 2, on the other hand, allocates attention to the various activities that demand attention, such as preparing for the starter gun in a race, and maintaining a faster walking speed than is normal for a person. 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. 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. 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. The theory proposes that both processing and storage are mediated by activation and that the total amount of activation available in working memory varies among individuals. capacity theory is that eort-attention 5 is a shared resource . Information was thought to be excluded from the central nervous system Moreno, tion of Broadbent's lter theory of attention which dates back to 1958. Discuss whether a person should focus attention on his or her own movements or on the movement effects. According to Kahneman, his theory is a capacity theory of attention, which means that: On the other hand, if the experiment does not direct the person to attend primarily to either task, performance on both tasks is compared to performance when each task is performed alone. Interestingly, all five players did not use the same visual search strategies. Although his book focuses primarily on problem solving and decision making as they relate to cognitive operations, it also presents concepts relevant to many of the perceptual and motor issues discussed throughout our book. That we spontaneously and involuntary allocate our visual attention to novel events such as these is well supported by research evidence (see Cole, Gellatly, & Blurton, 2001; and Pashler & Harris, 2001, for excellent reviews of this evidence). a metabolic expenditure that occurs inside the brain . In Thinking: Fast and Slow, Kahneman (2011) suggests that humans use two systems of thinking in making decisions. Most of these programs are sport specific. 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. . This means that the batter has less than 0.35 sec after the ball leaves the pitcher's hand to make a decision and to initiate the swing. Kahneman's (2011) most recent views of automaticity are presented in his best-selling book, Thinking, Fast and Slow. Both situations are important for the performance of motor skills. Automaticity is an important attention-related concept that relates primarily to skill performance in which the performer can implement knowledge and procedures with little or no demand on attention capacity. For an excellent review and discussion of the history and evolution of attention theories, see Neumann (1996). Kahneman, D. (1973). An elaborated capacity theory of attention has been proposed by Kahneman (1973), who identifies attention with a general pool of limited capacity or "mental . On one side, Broadbent (1957) argued that a selection filter existed early in processing . A theory of attention capacity that argues against a central capacity limit is the: Multiple-resource theory. The novices were students in a driver education class. Wickens' model describes these components. For specific references and summaries of the research demonstrating the "quiet eye" for these skills, see Wilson, Causer, & Vickers (2015) and Vickers (2007). Term. arousal the general state of excitability of a person, involving physiological, emotional, and mental systems. More specifically, a person's attention capacity will increase or decrease according to his or her arousal level. That is, the experienced drivers knew which cues were important and specifically searched for those cues. This bicycle rider, who can drink water, steer the bike, pedal the bike, maintain balance, see ahead to determine where to go and how to avoid road hazards, etc., demonstrates the simultaneous performance of multiple activities. A survey of cell phone owners reported that approximately 85 percent use their phones while driving, and 27 percent of those use the phones on half of their trips (Goodman et al., 1999; a summary of their report is available online at http://www.nhtsa.dot.gov). One is that in the one-on-one situations, the experienced players visually fixated longer on the opponent's hip region more than the less-experienced players, which indicated their knowledge of the relevant information to be acquired from the specific environmental feature. Results showed that before they began any prehensive action, their eyes moved to fixate on the target. Rationale and hypothesis for the study: A previous study by the first author (Porter, Wu, & Partridge, 2009) found that experienced track and field coaches of elite athletes typically provide instructions during practice and competition that emphasize the athletes' use of an internal focus of attention. While Kahneman's model is able to account for cognitive concepts such as multi-tasking, focalization, and shiftable/selective attention, Keele's Activation theory sought to improve upon the model by taking a . 1. C., Furley, You will find that researchers who study visual selective attention have used these same procedures. This grouping occurs automatically. 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. Three phases of the serve were of particular interest: the "ritual phase" (the 3.5 sec preceding the initiation of the serve); the "preparatory phase" (the time between the elevation of the arm for the ball toss and the ball's reaching the top of the toss); and the "execution phase" (from the ball toss to racquet-ball contact). 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. As a result the batter visually attends to the ball's rotation because of its salience as a visual cue about the type of pitch. 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. Participants acted as ball handlers as they viewed slides of typical attacking situations. Kahneman described attention as a reservoir of mental energy from which resources are drawn to meet situational attentional demands for task processing. Skilled individuals will be more likely to perform at their best when their arousal or anxiety levels are optimal for performing the skill in the situation they will experience. 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. For example, the multiple-resource view would explain variations in the situation involving driving a car while talking with a passenger in the following way. In contrast to Wulf and colleagues, Beilock argues that the appropriate focus of attention is determined by the performer's skill level. Some tasks might be relatively automatic (in that they make few demands in terms of mental effort . . Juggling on a high wire: Multitasking effects on performance. Open skills involve moving objects that must be visually tracked, which makes the visual search process different from that used for closed skills. These events can be visual or auditory. This means that the person must search as soon as possible for the cues that will provide information about the direction, speed, landing point, and bounce characteristics of the ball so that he or she can select, organize, and execute an appropriate return stroke. Returning a badminton serve. When you are driving your car on an open highway that has little traffic, it is relatively easy for you to carry on a conversation with a passenger in the car or on a cell phone (although it is illegal in many states in the United States and countries) at the same time. His theory proposes that our attention capacity is a single pool of mental resources that influences the cognitive effort that can be allocated to activities to be performed. They pointed out that research evidence has demonstrated the lack of benefit derived from generalized visual training programs, such as those often promoted by sports optometrists (e.g., Wood & Abernethy, 1997). Shifting from early to late selection models reduces the significance of stimuli . For example, detecting performance-related information in the environment as we perform a skill can be an attention-demanding activity. If the distinctive feature is a part of several cues, the search slows as the person assesses each cue in terms of how its characteristics match those of the target. This means that somewhere along the stages of information processing, the system has a bottleneck, where it filters out information not selected for further processing (see figure 9.1). Vickers, A., Brunner, ", Internal focus: "When you are attempting to jump as far as possible, I want you to focus your attention on extending your knees as rapidly as possible.". Many factors determine how much attentional capacity can be allocated and how much is needed for each task. The narrower the bottleneck, the lower the rate of flow. Kahneman's model of attention. In results similar to those of Shank and Haywood, the batters' visual attention involved the release point. J. J., & Temprado, The important difference between experts and novices was that the visual search patterns of the expert players allowed them to correctly identify the serve sooner than novices could. (See Wolfe, 2014 and Hershler & Hochstein, 2005, for an extended discussion of feature integration theory and factors that influence the "pop out" effect.). It is also important to note that visual search does not always mean that a person performing a motor skill is actively seeking cues in the environment to respond to. The expert players correctly identified almost every pitch, whereas the novices were correct only about 60 percent of the time. These examples raise an important human performance and learning question: Why is it easy to do more than one thing at the same time in one situation, but difficult to do these same things simultaneously in another situation? structural interference vs. capacity interference. Suddenly you hear someone near you mention your name in a conversation that person is having with other people. A heuristic is our automatic brain at work. [From Kahneman, D. (1973). This theory indicates that during visual search, we initially group stimuli together according to their unique features, such as color or shape. It is also thought to be the basis for what is commonly referred to as choking under pressure (Beilock, 2010; Beilock & Carr, 2001). 15 people (mean age = 68.3 yrs) with Parkinson's disease (PD) and 15 comparison people (mean age = 67.7 yrs) without PD. Thinking Fast and Slow. As a person becomes more skillful, his or her visual attention becomes increasingly more attuned to detecting the important kinematic features, which provides the skilled player an advantage over the less-skilled player in anticipating the opponent's action in a situation. If the theory is correct, then the attention schema, the construct of awareness, is relevant to any type of information to which the brain can pay attention. Kelley, For example, the rotation characteristics of a pitched baseball are highly meaningful to a batter in a game situation. Education. sensory modality to one with untapped reserve capacity. (For a discussion of the neural basis of selective attention, see Yantis, 2008.). No significant differences were found between handheld and hands-free cell phone use for the number of missed traffic signals and RT (a result that is problematic for a multiple-resource theory of attention). The answer to this question comes from the study of attention as it relates to the performance of multiple activities at the same time. Or, consider why you become distracted while driving your car when a ball rolls onto the street in front of you. But when the performer engages in an external focus of attention, the automatic (i.e., nonconscious) processes control performance. Kahneman' s theory of attention as eort is to understand eort as. Attention is involved in the selective directedness of our mental lives. Perform the coin transfer task and the digit subtraction task while standing. [Based on discussion in Goulet, C. et al. 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, the most commonly accepted reason is the constrained action hypothesis, which was proposed by Wulf and her colleagues (e.g., McNevin, Shea, & Wulf, 2003; Wulf, McNevin, & Shea, 2001). J. J. The players performed jump shots at a basket on the basis of the actions of the defensive players in the video. Roughly corresponding to conscious and unconscious processing. In their article, Strayer and Johnson reported a series of experiments in which participants engaged in a simulated driving task in a laboratory. In addition to the capacity limits of attention, the selection of performance-related information in the environment is also important to the study of attention as it relates to the learning and performance of motor skills. Procedure. Nideffer (1993) showed that the broad and narrow focus widths and the external and internal focus directions interact to establish four types of attention-focus situations that relate to performance. Krista A. Meuli. Task and performance environment: The participants performed the standing long jump indoors on a black rubber composite floor mat from a start line clearly marked at one end. Cell phone conversations did not reflect this shared awareness. Kahneman's capacity model. action effect hypothesis the proposition that actions are best planned and controlled by their intended effects. The researchers concluded that to successfully shoot a jump shot, players determine their final shooting movement characteristics by visually searching for and using information detected until they release the ball. This type of theoretical viewpoint remained popular for many years, until it became evident that the filter theories of attention did not adequately explain all performance situations. This final gaze fixation is the "quiet eye" (i.e., the "quiet" portion of the visual search process). As a person experiences performing in certain environments, critical cues for successful performance are invariant and increase in their meaningfulness, often without the person's conscious awareness. This means that when we graph this relationship, placing on the vertical axis the performance level ranging from poor to high, and placing on the horizontal axis the arousal level ranging from very low to very high, the plot of the relationship resembles an inverted U. R. (2012). Edit. Theories concerning how we select certain cues in the environment address the selection of cues for nonmoving as well as moving objects. 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). Analyzes how treisman pointed out a number of flaws in broadbent's . First, research evidence has shown consistently that it is possible to give attention to a feature in the environment without moving the eyes to focus on that feature (see Henderson, 1996; Zelinsky et al., 1997; and Brisson & Jolicoeur, 2007, for reviews of this evidence). 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. In agreement with and extending this conclusion, de Oliveira, Oudejans, and Beek (2008) showed that visual information was continuously being detected and used until the ball release, which demonstrated a closed-loop basis for control of shooting the ball. In their review of the visual attention research literature, Egeth and Yantis (1997) concluded that these two types of visual attention control "almost invariably interact" (p. 270). H. L., & Stelmach, More recently, Kato and Fukuda (2002) investigated the eye movements of nine expert baseball batters as they viewed the pitcher's motion during different types of pitches. Thus, in the absence of a voluntary intention by a media user to pay attention to or remember a specific type of content, automatic . Procedures: All participants performed five consecutive jumps, with a seated two minute rest between jumps. The term automaticity is commonly used to indicate that a person performs a skill or engages in an information-processing activity with little or no demands on attention capacity. In this competitive situation, the person's coach is very meaningful to the athlete. A., Williams, Vickers also described an interesting point that is relevant to our discussion on visual attention. We described one of these invariant features in chapter 7 when we discussed the importance of the use of time-to-contact information to catch a ball, contact or avoid an object while walking or running, and strike a moving ball. They monitored eye movements of novice and experienced drivers as they watched various driving-related scenes that included at least one dangerous situation. The nature of this selectivity is one of the principal points of disagreement between the extant theories of attention. 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). When the arousal level is optimal, sufficient attentional resources are available for the person to achieve a high level of performance. This div only appears when the trigger link is hovered over. The two bubbles colored yellow are adapted from Kahneman's Figure 3.3 (1973, pp. L., Philippaerts, A capacity theory of attention offers an alternative to theories that explain man's limitations by assuming structural bottlenecks exist. In the discussion of attention and the visual selection of performance-relevant information from the environment, we discussed the following: Visual selective attention to performance-relevant information in the environment is an important part of preparing to perform a motor skill. This window, which lasts from about 83 msec before until 83 msec after racquet-shuttle contact, provides information about racquet movement and shuttle flight that seems to resolve uncertainty about where the served shuttle will land.
