These diverse effects of storytelling modes are highly relevant to financial decision-making, where there is a growing recognition of the impact of narrative processing and message framing on consumers' choice over the premises of rational choice theory and of the analytical system of thinking (Kahneman and Tversky, 1979, Kahneman, 2003). Unfortunately, this late-nineteenth- and early-twentieth-century emphasis on attention soon waned, as those under the influence of behaviorism deemed the study of attention no longer relevant to the understanding of human behavior. The reason an external focus of attention results in better skill performance has been the subject of some debate (see Wulf, 2013 and Wulf & Prinz, 2001, for a discussion of the various issues in this debate). The performer usually engages in an active visual search of the performance environment according to the information needed to prepare and perform an intended action, although sometimes the environmental information attended to provides the basis for selecting an appropriate action. Without going further into the theory issues involved, the common coding view predicts that actions will be more effective when they are planned in terms of their intended outcomes rather than in terms of the movement patterns required by the skill. First, notice that the central pool of available resources (i.e., available capacity) is represented as a box at the top of the model. 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). He presented an example of a reaching/aiming movement to illustrate his point: "Keep your eye at the place aimed at, and your hand will fetch [the target]; think of your hand, and you will likely miss your aim" (p. 520). Farrow, B. In this competitive situation, the person's coach is very meaningful to the athlete. A., Williams, This means that arousal levels that are too low or too high lead to poor performance, because the person does not have the attentional resources needed to perform the activity. To visit the website of the laboratory of one of the authors of the research on the effect of video games on visual attention (Green & Bavelier, 2003), and to experience the tasks involved in these and related experiments, go to http://cms.unige.ch/fapse/people/bavelier, To watch a video of the "invisible gorilla experiment" (referred to in this video as the "monkey business illusion"), which demonstrates how focusing visual attention on a specific feature of a situation can keep you from observing other features in the scene (known as "inattentional blindness"), go to http://www.youtube.com/watch?v=IGQmdoK_ZfY, To read a ScienceDaily.com story "Distracted driving up among students," go to http://www.sciencedaily.com/releases/2012/04/120424120448.htm. For example, Poldrack and his associates (Poldrack et al., 2005) used fMRI procedures to show that different brain areas are active in the following situation. . In terms of novel visual events, think about why fans at a basketball game who sit behind the basket like to stand and wave objects in the air while a player is attempting to shoot free throws. The brain circuitry of attention. A heuristic is our automatic brain at work. 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. For example, the rotation characteristics of a pitched baseball are highly meaningful to a batter in a game situation. Specific closed skills demonstrations of the "quiet eye." 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. gained acceptance by researchers today is the limited capacity theory by Kahneman (1973). Otherwise it is hidden from view. Kahneman described attention as a reservoir of mental energy from which resources are drawn to meet situational attentional demands for task processing. We allocate attention to the most meaningful features. C., Teasdale, (For a discussion of the neural basis of selective attention, see Yantis, 2008.). According to some attention theories, there is a central reservoir of resources for which all activities compete. Activity-specific training programs facilitate the use of effective visual search strategies more successfully than general-vision training programs. Affective influences of selective attention. Procedure. However, researchers disagree about whether beginners should focus their attention externally or on aspects of the movement. In their article, Strayer and Johnson reported a series of experiments in which participants engaged in a simulated driving task in a laboratory. They found that the time between the initiation of the badminton server's backswing and the shuttle's hitting the floor in the receiver's court is approximately 400 msec (0.4 sec). Note: A select number of articles and book chapters, as well as the entire text of Dr. Kahneman's 1973 book Attention and Effort, are available online. 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. These two systems that the brain uses to process information are the focus of Nobelist Daniel Kahneman's new book, Thinking, Fast and Slow (Farrar, Straus and Giroux, LLC., 2011). Academic Press. Scientists have known for many years that we have attention limits that influence performance when we do more than one activity at the same time. An experiment by Cockrell, Carnahan, and McFayden (1995) demonstrated this role for visual search. 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. 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. Noise is a reality of . Concept: Preparation for and performance of motor skills are influenced by our limited capacity to select and attend to information. People's ability to maneuver through environments like these indicates that they have detected relevant cues and used them in advance to avoid collisions. For example, if a pianist is constantly switching visual attention from the written music to the hands and keys, he or she will have difficulty maintaining the precise timing structure required by the piece being played. J. J. Thus, the more distinctive the feature is that identifies the target of the visual search, the more quickly the person can identify and locate the target. Kahneman described attention as a reservoir of mental energy from which resources are drawn to meet situational attentional demands for task processing. Automaticity is an important concept in our understanding of attention and motor skill performance. Attention and Effort" was a major work of kahneman (Kahneman, 1973). While concentrating on your professor during a lecture, haven't you been distracted when a classmate has dropped some books on the floor? Theoretical Interpretations of Divided Attention. . Richard A. Magill, and David I. Anderson. Therefore, we know that as people become more experienced and skilled in an activity, they acquire better visual search skills. 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. More specifically, a person's attention capacity will increase or decrease according to his or her arousal level. Or, consider why you become distracted while driving your car when a ball rolls onto the street in front of you. You will see a variety of examples of the use of the dual-task procedure in this chapter and others in this book. ), The selection of features of interest occurs when a person focuses the attentional spotlight on the master map of all features. J. N., & Williams, Skills such as de termining where to direct a pass in soccer or hockey, or deciding which type of move to put on a defender in basketball or football, are all dependent on a player's successful attention to the appropriate visual cues prior to initiating action. Consider some other examples in which doing more than one activity at a time may or may not be a problem. A common concern throughout the world is the use of cell phones by people who are driving motor vehicles. In results similar to those of Shank and Haywood, the batters' visual attention involved the release point. 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). Automatic. The amount of available resources (i.e., attention capacity . 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). 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. Participants were required to walk 3.75 m to a table and pick up an aluminum can or a pencil as they walked by. The capability to do more than one activity simultaneously when performing a motor skill can be situation-specific. 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. Around the same time as Kahneman produced his model, Shiffrin and Schneider (1977) made an important distinction between two modes of processing: Controlled. J., Mcobert, S. G., Broome, Although the specific definition of this concept is difficult to identify, there is general agreement that it refers to our limited capability to engage in multiple cognitive and motor activities simultaneously (commonly referred to as "multitasking") and our need to selectively focus on specific environmental context features when we perform motor skills. W. S. (2014). For example, if a physical therapist tells a patient to "pay close attention to where you place your foot on the stair step," the patient has the "momentary intention" to allocate his or her attention according to the therapist's instruction. In some instances, the laws prohibit the use of both handheld and hands-free cell phones, while in other cases, laws allow hands-free cell phone use. In addition, they found that the expert players visually focused on different kinematic information of their opponents than the nonexperts. Finally, three general rules influence how people allocate attentional resources. This is a description of how demanding the processing of a particular input might be. (2015). 15 people (mean age = 68.3 yrs) with Parkinson's disease (PD) and 15 comparison people (mean age = 67.7 yrs) without PD. Our success in performing two or more tasks simultaneously depends on whether those tasks demand our attention from a common resource or from different resources. An important historical root of capacity theory lies in the human . Multiple-resource theories provide an alternative view of a limited capacity view of attention by proposing that several different resource pools exist from which attention can be allocated. Kahneman's (2011) most recent views of automaticity are presented in his best-selling book, Thinking, Fast and Slow. A. L., Pesaran, In addition to having to allocate attention among several activities, people also direct attention to specific features of the environment and to action preparation activities. Each resource pool is specific to a component of performing skills. This means that in most performance situations, our intentions and goals as well as certain characteristics in the environment influence our visual attention. Researchers have disputed since the end of the nineteenth century about whether visual selective attention is active or passive (sometimes phrased as "top-down or bottom-up," or "goal directed or stimulus driven"). The theory basis for this hypothesis relates to how we code sensory and motor information in memory. . 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). Visual search and intended actions. This area of study is commonly referred to as selective attention. Second, the low-handicap golfers directed more eye movement fixations to the ball during this phase than the high-handicap golfers, who directed more fixations to the putter. Life is mostly about choices. G., & Vickers, But, some problems require more effort to solve; they require effortful mental activities that are also influenced by experience and practice. 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. 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. Describe how you can simultaneously perform these multiple activities by identifying what you think about, what you do not think about, and what you visually focus on as you perform these activities. However, it is not possible to make an eye movement without a corresponding shift in attention. Moreno, Kahneman (1973) developed the . Vickers reported that during a series of putts, several differences were found between these two groups during the interval of time just after the golfer completed positioning the ball and just before the initiation of the backswing of the putter (i.e., the preparation phase). An example of one of these types of characteristics is that the event is novel for the situation in which it occurs. These are the same two sources involved in providing attentional resources for carrying on a conversation with a friend. The resources are specific to a component of performing a skill. Reprinted by permission of the author.]. To determine if attention capacity is required throughout the performance of a motor skill. The attention demands are of particular importance to Kahneman's theory and can be easily understood through Figure 1, where attention capacity is represented by a large flexible circle, and all activities situated within the circle are represented by smaller circles (Anderson & Magill, 2017). To articulate pertinent theories of cognitive biases, I first turn to the Nobel laureate psychologist Kahneman's (2011) theory of the dual systems of thinking, a fundamental cornerstone in the study of cognitive biases. . This is described by Kahneman below. 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). Isn't it difficult to carry on a conversation with your passenger or on your phone while driving under these conditions? R., Zeuwts, Allocation of attentional resources is determined by characteristics of the activities and the allocation policy of the individual, which in turn is influenced by situations internal and external to the individual. 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. A child learning to dribble a ball has difficulty dribbling and running at the same time, whereas a skilled basketball player does these two activities and more at the same time. Within this model, attention is assumed to be flexible, allowing different depths of perceptual analysis. 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). Because of the assumed limited channel capacity of the central nervous system, some device was postulated that would reduce the information inflow from the senses and so prevent overload. The distance jumped was recorded at the end of each jump from the back of the heel that was closest to the start line. Type "Kahneman" in the Search box to locate the autobiography and other features related to his Nobel Prize. The most influential alternative proposed that information-processing functions could be carried out in parallel rather than serially, but attention limits were the result of the limited availability of resources needed to carry out those functions. A., Snelgrove, This means that the amount of available attention can vary depending on certain conditions related to the individual, the tasks being performed, and the situation. The results indicated these things: Participants missed two times more simulated traffic signals when they were engaged in cell phone conversations; and, when they responded correctly to the signals (i.e., red lights), their reaction time (RT) was significantly slower than when they were not using the cell phone. System 1 operates automatically and quickly with little or no effort or sense of voluntary control. Fixations on the club led to more missed putts, whereas fixations on the ball led to more successful putts. The result is that people have a tendency to direct visual attention to them. There are some situations in sport in which researchers can determine the actual amount of time a person has to engage in visual search and to prepare an action. This system enables us to solve certain problems (mental, perceptual, and motor) by relying on intuition that has developed through learning, which typically results from experience and practice. Shooting a basketball. The final gaze fixation (i.e., the "quiet eye") during the performance of open skills is on the moving object, which the eye then tracks for as long as possible before initiating the required movement. 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. The answer to this question comes from the study of attention as it relates to the performance of multiple activities at the same time. Two results are especially noteworthy. (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. 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). When a pitcher throws a ball at a speed of 90 mi/hr, it will arrive at home plate in approximately 0.45 sec. This final gaze fixation is the "quiet eye" (i.e., the "quiet" portion of the visual search process). The most common experimental procedure used to investigate the attention demands of motor skill performance is called the dual-task procedure. As a person walks from one end of a hallway to the other, he or she must listen to words spoken through earphones; when the person hears each word, he or she must repeat the word that was spoken just prior to that word (i.e., the secondary task is a short-term memory task that involves interference during the retention interval).
