Introduction
In general, my main research interest is the role of attention and perception in human performance of motor skills. Specifically, I am interested in the role that visual attention plays when learning complex skills such as flying an aircraft or performing surgery.

The purpose of this review was to examine the literature on gaze behavior in referees. A literature search found only 12 relevant studies. Five of those studies were conducted on referees in association football (soccer), three on judges in gymnastics, one on softball umpires, and one each on referees in team handball, rugby, and ice hockey. Seven...

The purpose of the current study was to examine whether a wide bandwidth knowledge of results (WBWKR) would result in better throwing accuracy and consistency compared to a narrow bandwidth knowledge of results (NBWKR) among goalball players with visual impairments. Elite goalball players (n=14) were randomly assigned to one of two groups-a WBWKR o...
Article
In radiology, 60% to 80% of diagnostic errors are perceptual. The use of more efficient visual search behaviors is expected to reduce these errors. We collected eye-tracking data from participants with different levels of experience when interpreting chest X-rays during the completion of a pathology-detection task. Eye-tracking measures were assess...

The number of aviation accidents has declined in the past decades but there are still, unfortunately, fatal accidents, many of which are caused by pilot error. Risk factors for these accidents include failures in perception and situation awareness and failure in monitoring flight parameters. These risk factors can be reduced by maintaining optimal...

The purpose of the current study was to examine the effectiveness of providing autonomy to learners and the phenomenon of preference-performance dissociation on a closed, self-paced motor task – putting in golf, when using different placements of a visual aid (a large circle) around a golf hole. Seventy-six participants were assigned to four experi...

Background: Randomization provides an equal chance for participants to be allocated to intervention groups, in order to create an equal distribution of all variables at baseline in all groups. However, this is not guaranteed, particularly if the groups are too small, or if the researched groups consist of older adults. The aims of this commentary...

This project aimed to evaluate effects of ambient lighting during practice and performance of simulated helicopter escape sequences. Participants were randomized to one of the following groups to practice a standard helicopter underwater escape sequence: Light (with room lights on), Dark (with room lights off), or Graduated (in the light for the fi...
Article
Gaze behavior in general, and the quiet eye (QE) in particular, are integral to the performance of closed, self-paced motor tasks. This review examines the relationship between the QE (and a number of other gaze properties) and golf-putting performance. An analysis of 26 studies revealed conflicting results. For example, while some studies showed t...
Article
Perceptual-cognitive skills enable an individual to integrate environmental information with existing knowledge to be able to process stimuli and execute appropriate responses on complex tasks. Various underlying processes could explain how perceptual-cognitive skills impact on expert performance, as articulated in three theoretical accounts: (a) t...
Article
Full-text available
One important concept of experimental design is the random assignment of participants to experimental groups. This randomization process is used to prevent selection bias, as well as to provide a strong basis for a cause-and-effect relationship between the independent variable/s and the dependent variable/s. In small sample sizes, simple randomizat...
Article
The performance of motor tasks can be improved by enhanced performance expectancies. The purpose of the current study was to examine whether providing relatively easy performance criteria to golfers improves their golf-putting accuracy. More specifically, our aim was not only to replicate a previous study (Ziv, G., Ochayon, M., & Lidor, R. 2019. En...

The purpose of the current study was to examine the relationship between expertise, performance, and gaze behavior in a complex error-detection cockpit task. Twenty-four pilots and 26 non-pilots viewed video-clips from a pilot’s viewpoint and were asked to detect malfunctions in the cockpit instrument panel. Compared to non-pilots, pilots detected...
Article
Objective: To examine whether performance expectancies enhance or diminish the learning of a putting task in golf. More specifically, our aim was to replicate a previous study (Palmer, Chiviacowsky, & Wulf, 2016), but to add a control group, in order to more accurately assess whether a large circle around the target enhances putting performance and...
Chapter
Professionals involved in training programs aimed at improving the ability of handball players—coaches, strength and conditioning coaches, physiotherapists, athletic trainers, and sport physicians—should have access to information on the physical aspects of the handball players, so that they can use this information when planning short- and long-te...
Article
Full-text available
The decline in cognitive and motor functions with age affects the performance of the aging healthy population in many daily life activities. Physical activity appears to mitigate this decline or even improve motor and cognitive abilities in older adults. The current systematic review will focus mainly on behavioral studies that look into the dual e...

Article
Closed, self-paced tasks are typically performed in a stable environment, but some features of the environment may vary (e.g., quiet/noisy conditions) or may negatively influence the outcome of performance. Optimal gaze behavior, and specifcally long quiet eye (QE) durations, has been found to be associated with improved performance of closed, self-...

The purpose of the current study was to explore the influence of the distance of a wall located behind the hole in performing a putt in golf. Our assumption was that a performance condition where the wall is located a short distance behind the hole would help novices minimize any left/right directional bias. Novice golfers performed a putting task...

In this study, eye-tracking data were collected from students with different levels of experience in interpreting chest X-rays during the completion of a pathology-detection task. Three theories were put forward to understand the link between visual search behavior and underlying neuronal processes: The long-term working memory theory, the information-reduction hypothesis, and the holistic model of image perception.
