Bimodal Condition

Due to lack of visual or auditory perceptual information, many tasks require interpersonal coordination and teaming. Dyadic verbal and/or auditory communication typically results in the two people becoming informationally coupled. This experiment examined coupling by using a two-person remote navigation task where one participant blindly drove a remote-controlled car while another participant provided auditory, visual, or a combination of both cues (bimodal). Under these conditions, we evaluated performance using easy, moderate, and hard task difficulties. We predicted that the visual condition would have higher performance measures overall, and the bimodal condition would have higher performance as difficulty increased. Results indicated that visual coupling performs better overall compared to auditory coupling and that bimodal coupling showed increased performance as task difficulty went from moderate to hard. When auditory coupling occurs, the frequency at which teams communicate affects performance— the faster teams spoke, the better they performed, even with visual communication available.

Medium Group

Responses on the Activation–Deactivation Adjective Check List were recorded for forty–eight subjects who were performing a visual perceptual information processing task at one of three levels of task difficulty. In general, significant task performance differences in the expected direction were recorded. Two of the activation measures were found to differentiate between low and high task difficulty groups, while the scores for the medium group fell between these two-but did not significantly differ from either. Gender differences for both performance and activation measures were largely not significant.

And Task

We report here the first experiment of a series studying the effect of task structure and difficulty demand on time-sharing performance and workload in both automated and corresponding manual systems. The experimental task involves manual control time-shared with spatial and verbal decisions tasks of two levels of difficulty and two modes of response (voice or manual). The results provide strong evidence that tasks and processes competing for common processing resources are time shared less effectively and have higher workload than tasks competing for separate resources. Subjective measures and the structure of multiple resources are used in conjunction to predict dual task performance. The evidence comes from both single task and from dual task performance.

Abstract Humans often unconsciously coordinate behaviour with that of others in daily life. This interpersonal coordination, including mimicry and interactional synchrony, has been suggested to play a fundamental role in social interaction. If this coordinative behavior is socially adaptive, it may be shared with other highly social animal species. The current study targeted chimpanzees, which phylogenetically are the closest living relatives of humans and live in complex social groups and examined whether interactional synchrony would emerge in pairs of chimpanzees when auditory information about a partner’s movement was provided. A finger-tapping task was introduced via touch panels to elicit repetitive and rhythmic movement from each chimpanzee. We found that one of four chimpanzees produced significant changes in both tapping tempo and timing of the tapping relative to its partner’s tap when auditory sounds were provided. Although the current results may have limitations in generalizing to chimpanzees as a species, we suggest that a finger-tapping task is one potential method to investigate interactional synchrony in chimpanzees under a laboratory setup.

And Task

Ss were required to perform both central and peripheral perceptual tasks presented simultaneously by means of 200-msec. tachistoscopic flashes. The central task, requiring the discrimination between 2 lines on the basis of length, was progressively increased in difficulty from Test I to Test III. Peripheral task performance required the estimation of the number of black dots surrounding the central task. This number varied randomly between 1 and 8. Half the Ss in each test performed these tasks under stress (hand in ice-water), the other Ss under no stress. A significant interaction ( p < .01) was found; the stress group was inferior to the no-stress group on the peripheral task when the central task was relatively easy (Test I) but was superior to the no-stress group when the central task was extremely difficult (Test III). The results were interpreted in terms of the dependence of the “range of cue utilization” upon the degree of difficulty of the perceptual material as well as arousal level.

And Task

This paper describes a study on the sense of presence and task performance in a virtual environment as affected by copresence (one subject working alone versus two subjects working as partners), level of control (control of movement and control of navigation through the virtual environment), and head tracking. Twenty subjects navigated through six versions of a virtual environment and were asked to identify changes in locations of objects within the environment. After each trial, subjects completed a questionnaire designed to assess their level of presence within the virtual environment. Results indicated that collaboration did not increase the sense of presence in the virtual environment, but did improve the quality of the experience in the virtual environment. Level of control did not affect the sense of presence, but subjects did prefer to control both movement and navigation. Head tracking did not affect the sense of presence, but did contribute to the spatial realism of the virtual environment. Task performance was affected by the presence of another individual, by head tracking, and by level of control, with subjects performing significantly more poorly when they were both alone and without control and head tracking. In addition, a factor analysis indicated that questions designed to assess the subjects' experience in the virtual environment could be grouped into three factors: (1) presence in the virtual environment, (2) quality of the virtual environment, and (3) task difficulty.

Level Of Difficulty

This paper describes two methodological innovations in the study of adaptive training. The first is the use of a yoked design to insure that the average level of task difficulty for fixed-difficulty subjects is the same as the average level of difficulty reached by adaptive subjects. The second is the demonstration of the feasibility of using a secondary (subsidiary, non-loading) task to furnish the adaptive criterion for changing the difficulty level of the primary task. The results of two experiments are reported. Both experiments demonstrate the feasibility and utility of yoked design and adaptation on secondary task performance in adaptive training.
