correlational measures are computed across a number of trials, performance changes between different vision conditions could naturally come about both through changes in online feedback utilization (e.g., Hansen, Tremblay, & Elliott, 2005 ) and in offline feedback utilization (e.g., Plamondon & Alimi, 1997

The objective of the current study was to determine whether the reliance on visual feedback that develops with practice is to due utilizing vision to adjust trajectories during movement execution (i.e., online) and/or to enhance the programming of subsequent trials (i.e., offline). Participants performed a directional aiming task with either vision during the movement, dynamic feedback of the trajectory of the movement or the movement endpoint. The full vision condition was more accurate during practice than the other feedback conditions but suffered a greater decrement in performance when feedback was removed. In addition, the reliance on trajectory feedback was greater compared with the endpoint feedback. It appears that the reliance on visual feedback that develops with practice was due to both online and offline processing.

This study examined the advertisement structure of online and off-line broadcasts as consumer drivers to Web sites through the integration of specific calls to action. Content analysis was performed on ads aired during the online and off-line broadcasts of an NCAA Men’s Basketball Tournament. The key finding of this research is that communication and technology companies value advertising during online sporting-event broadcasts, because these companies were significantly more visible during the online broadcasts than the television broadcasts (χ2 = 6.67, p = .017). A much higher percentage of online ads were shorter (15 seconds) in duration (χ2 = 7.029, p = .01), appealed to fantasy (χ2 = 8.494, p = .004), and used advertising execution techniques emphasizing new products or features (49%) more often than in television ads (18%; χ2 = 11.078, p = .001). The findings provide insight into how calls to action in advertisements during Webcasts and traditional television offerings can move consumers to Web sites.
This investigation tested the proposal that a “highly accurate” and temporally unstable stored target representation is available to the motor system for the online control of memory-guided reaches. Participants reached to a target that was: (a) visible during the response, (b) extinguished at movement onset, and (c) occluded for 0, 500, 1500 and 2,500 ms in advance of response cueing. Additionally, trials were performed with (i.e., limb visible) and without (i.e., limb occluded) vision of the reaching limb. Results showed that limb occluded trials undershot the target location in each target condition, and were characterized by a primarily offline mode of control. In contrast, limb visible trials showed a consistent level of endpoint accuracy for each target condition and elicited more online reaching corrections than limb occluded trials. It is therefore proposed that a reasonably accurate and temporally stable stored target representation can be combined with vision of the moving limb for the online control of memory-guided reaches.

On the contrary, this use is strongly related to intensive off-line relations and interactions with peers, whose influence on teens’ substance onset and use has been long demonstrated. 47 In

How professional team-based sport organizations can optimize their e-service platform and manage their brand in an increasingly multichannel marketing environment is a critical issue. This study examines how sports consumers’ (i.e., fans’) perceptions of e-service quality, brand strength, and image congruency between the sport brands’ offline image and online image affects the development of consumers’ trust in the team’s website. In addition, the study explores the role of team website trust in developing team website loyalty, as well the role of loyalty in actual purchase frequency from the teams’ website. Data were collected via an online survey of sports consumers of e-services delivered by professional sport teams. The results indicate that sport team brand strength, followed by teams website e-service quality and brand image congruency between the teams online and offline activity are significant determinants of trust in the teams’ website, with online trust strongly influencing website loyalty intentions.

The purpose of the present study was to establish the contribution of visual feedback in the correction of errors during movement execution (i.e., online) and the utilization of visual feedback from a completed movement in the programming of upcoming trials (i.e., offline). Participants performed 2 dimensional sweeping movements on a digitizing tablet through 1 of 3 targets, which were represented on a video monitor. The movements were performed with and without visual feedback under 4 criterion movement times (150, 250, 350, 450 msec). We analyzed the variability in directional error at 25%, 50%, 75%, and 100% of the distance between the home position and the target. There were significant differences in variability between visual conditions at each movement time. However, in the 150-msec condition, the form of the variability profiles did not differ between visual conditions, suggesting that the contribution of visual feedback was due to offline processes. In the 250-, 350-, and 450-msec conditions, there was evidence for both online and offline control, as the form of the variability profiles differed between the vision and no vision conditions.

The authors manipulated the availability of monocular and binocular vision during the constituent planning and control stages of a goal-directed reaching task. Furthermore, trials were completed with or without online limb vision to determine whether monocular- or binocular-derived ego-motion cues influence the integration of visual feedback for online limb corrections. Results showed that the manipulation of visual cues during movement planning did not influence planning times or overall kinematics. During movement execution, however, binocular reaches—and particularly those completed with online limb vision—demonstrated heightened endpoint accuracy and stability, a finding directly linked to the adoption of a feedback-based mode of reaching control (i.e., online control). In contrast, reaches performed with online monocular vision produced increased endpoint error and instability and demonstrated reduced evidence of feedback-based corrections (i.e., offline control). Based on these results, the authors propose that the combination of static (i.e., target location) and dynamic (i.e., the moving limb) binocular cues serve to specifically optimize online reaching control. Moreover, results provide new evidence that differences in the kinematic and endpoint parameters of binocular and monocular reaches reflect differences in the extent to which the aforementioned engage in online and offline modes of movement control.
This case study examines contemporary recreational sports practitioners’ communication practices and social tie formation from the perspective of two lifestyle sports disciplines: climbing and trail running. Online survey results from 301 climbers and trail runners from Finland indicate that computer-mediated communication (CMC) has established its place in recreational lifestyle sports cultures; however, it has not done it at the expense of face-to-face (FtF) communication. Online interaction produces weak social ties with instrumental and informative value, but physical location is essential in establishing ties with emotional and appraisal value. This paper argues that it is the sports subculture and individual practitioners’ needs that define how interaction is realized, and what importance different online and off-line communication practices have. Besides studying communication practices, this case study explores the social meanings practitioners attribute to their social contacts.
