Chronological Sequence

An eye tracker experiment investigated 4-, 6-, and 8-year old children’s cognitive processing of film cuts. Nine short film sequences with or without editing errors were presented to 79 children. Eye movements up to 400 ms after the targeted film cuts were measured and analyzed using a new calculation formula based on Manhattan Metrics. No age effects were found for jump cuts (i.e., small movement discontinuities in a film). However, disturbances resulting from reversed-angle shots (i.e., a switch of the left-right position of actors in successive shots) led to increased reaction times between 6- and 8-year old children, whereas children of all age groups had difficulties coping with narrative discontinuity (i.e., the canonical chronological sequence of film actions is disrupted). Furthermore, 4-year old children showed a greater number of overall eye movements than 6- and 8-year old children. This indicates that some viewing skills are developed between 4 and 6 years of age. The results of the study provide evidence of a crucial time span of knowledge acquisition for television-based media literacy between 4 and 8 years.

Lay Public

With the proliferation of neuroscience-related messages in popular media, it is more important than ever to understand their impact on the lay public. Previous research has found that people believed news stories more when irrelevant neuroscientific explanations were added. We sought to reveal whether such information could cause a change in social behavior. Specifically, based on publicized findings of the relationship between social behavior and the neurotransmitter oxytocin, we proposed that participants would accept more strangers into their in-group, or alternatively decrease in-group size, if told that there were oxytocin-based (relative to psychological construct-based) health benefits for doing so. In two tasks, participants were shown faces and written information about stimuli that could match their race, politics, and religion to varying degrees. In spite of evidence that participants processed the primes, and were sensitive to their level of similarity with stimuli, oxytocin-based priming did not alter categorization, or pupil dilation. It did not alter cross-race viewing behavior, as measured by an eye tracker, in consistent ways. Unexpectedly, pupil dilation increased when viewing stimuli of the same religion, an effect entirely related to White liberal Christians viewing other Christians. Overall, these results suggest that neuroscience information may impact some judgments, but lay people will not alter their likelihood of acceptance of strangers simply because they were primed with a neuroscience- (or more specifically, neurotransmitter-) based reason for doing so.

Diameter Change

Through an urban tunnel-driving experiment, this paper studies the changing trend of drivers’ visual characteristics in tunnels. A Tobii Pro Glasses 2 wearable eye tracker was used to measure pupil diameter, scanning time, and fixation point distribution of the driver during driving. A two-step clustering algorithm and the data-fitting method were used to analyze the experimental data. The results show that the univariate clustering analysis of the pupil diameter change rate of drivers has poor discrimination because the pupil diameter change rate of drivers in the process of “dark adaptation” is larger, while the pupil diameter change rate of drivers in the process of “bright adaptation” is relatively smooth. The univariate and bivariate clustering results of drivers’ pupil diameters were all placed into three categories, with reasonable distribution and suitable differentiation. The clustering results accurately corresponded to different locations of the tunnel. The clustering method proposed in this paper can identify similar behaviors of drivers at different locations in the transition section at the tunnel entrance, the inner section, and the outer area of the tunnel. Through data-fitting of drivers’ visual characteristic parameters in different tunnels, it was found that a short tunnel, with a length of less than 1 km, has little influence on visual characteristics when the maximum pupil diameter is small, and the percentage of saccades is relatively low. An urban tunnel with a length between 1 and 2 km has a significant influence on visual characteristics. In this range, with the increase in tunnel length, the maximum pupil diameter increases significantly, and the percentage of saccades increases rapidly. When the tunnel length exceeds 2 km, the maximum pupil diameter does not continue to increase. The longer the urban tunnel, the more discrete the distribution of drivers’ gaze points. The research results should provide a scientific basis for the design of urban tunnel traffic safety facilities and traffic organization.
