handwriting has not often been studied directly, especially in the preschool and early school years. We next discuss how a perception–action perspective can be used to examine the real-time deployment of visual-motor integration in handwriting development.

We used eye tracking to investigate where infants and adults directed their gaze on a scene right before reaching. Infants aged 5, 7, 9, and 11 months old and adults looked at a human hand holding an object out of reach for 5 s, then the hand moved the object toward the participant for reaching. We analyzed which part of the scene (the object, the hand, or elsewhere) infants and adults attended the most during those 5 s before reaching. Findings revealed that adults’ visual fixations were majorly focused on the object to reach. Young infants’ looking patterns were more widely distributed between the hand holding the object, the object, and other nonrelevant areas on the scene. Despite distributed looking on the scene, infants increased their amount of time looking at the object between 5 and 11 months. Nine- and 11-month-olds showed overall accumulated looking durations comparable to adults’ for most of the objects; however, 9-month-olds differed in their rate of gaze transition between scene areas. From the age of 5 months old, infants are able to sustain their gaze to the pertinent scene area when the scene contains a central object on which they will later be able to act.

Gain-framed messages are more effective at promoting physical activity than loss-framed messages. However, the mechanism through which this effect occurs is unclear. The current experiment examined the effects of message framing on variables described in the communication behavior change model (McGuire, 1989), as well as the mediating effects of these variables on the message-frame–behavior relationship. Sixty low-to-moderately active women viewed 20 gain- or loss-framed ads and five control ads while their eye movements were recorded via eye tracking. The gain-framed ads attracted greater attention, ps < .05; produced more positive attitudes, p = .06; were better recalled, p < .001; influenced decisions to be active, p = .07; and had an immediate and delayed impact on behavior, ps < .05, compared with the loss-framed messages. Mediation analyses failed to reveal any significant effects. This study demonstrates the effects of framed messages on several outcomes; however, the mechanisms underlying these effects remain unclear.

The purpose of this study was to examine whether prior biped tennis playing experience results in different visual search strategies compared with no prior biped playing experience. A total of 32 wheelchair (WC) tennis players, 17 males and 15 females, ranked between 1 and 16 on the International Tennis Federation rankings participated in this study. Half the players had prior experience playing tennis as a biped player, and half had no prior experience in biped tennis. The athletes viewed 18 different serves from an expert WC player while their gaze was monitored using eye tracking. Results revealed significant differences between the groups in fixation duration and number of fixations. Differences were also found in fixation locations and durations across biomechanical phases of the serve. The WC only players had more fixations for shorter periods than did WC with biped players in the ritual phase. In the preparatory and execution phases, however, the WC only players had fewer fixations for longer duration than the WC with biped players. Results are discussed in terms of long-term memory structures, learning, and considerations when coaching and training WC tennis players.

Previous studies have demonstrated that the media, by specifically framing news articles, may systematically affect a nondisabled recipient’s perception of athletes with disabilities (AWDs). However, it remains unclear how specific sports news frames affect a recipient’s quality perception of a journalistic product and if news frames further affect an individual’s postexposure behavior in social interaction with a person with a disability (PWD). To shed some light on these potential news-framing effects, 2 experimental studies (between-subjects designs) were conducted. Study 1 revealed systematic news framing’s effects on recipients’ attitudes toward a depicted AWD and showed effects on a recipient’s perceived quality of a news story. Study 2 further revealed that specific news frames may (automatically) affect a recipient’s behavior (e.g., verbal communication performance, visual attention/ eye contacts) in a subsequent face-to-face social interaction with a PWD. The findings are discussed regarding their implications for the journalistic coverage of disability sports in the media.

Children with autism spectrum disorder tend to have little interest in the presence, actions, and motives of other persons. In addition, these children tend to present with a limited and overly redundant movement repertoire, often expressing hyperfixation and aversion to novelty. We explore whether this is related to a more fundamental lack of appreciation for various temporal dynamics, including periodic, chaotic, and aperiodic motion structures. Seven children with ASD (age, gender, and height matched with children without ASD) were asked to stand and watch the motion of a visual stimulus displayed on a large (55") video monitor. Gaze and posture movements were recorded and assessed using cross recurrence quantification analysis for qualities of coordination, including rate and duration of bouts of coordination. Results showed that children with ASD do not express an affinity to chaotic motion of the stimulus in the same way as children without ASD. We contend that this indifference to chaotic motion is foundational to their general disinterest in biological motion.

Since vision is used in studies of muscle force control, reduced muscle force control might be related to reduced visual ability. We investigated relationships between steadiness in eye movements and quadriceps muscle torque (a surrogate for force) during isometric contractions of constant and varying torques. Nineteen young adults with an average age of 20.7 years and 18 old adults with an average age of 71.6 years performed three vision tasks, three vision and torque tasks at 40% maximal voluntary contraction (MVC), and three vision and torque tasks at 54 nm. Age groups had identical torque steadiness (CV) in 40%-MVC and 54-nm conditions (p > .05). Old had similar vertical (p > .05) but decreased horizontal visual steadiness (SD) (p < .05) compared with young. Correlations between visual steadiness and muscle torque steadiness failed to show a significant relationship (p > .05). We were unable to identify a substantial relationship between muscle torque steadiness and eye movement, as a component of visual steadiness, and conclude that reduced visual steadiness does not contribute to reduced muscle torque steadiness.
