Previous studies have designed educational methods to cultivate digital citizenship behavior and support the construction of knowledge. However, these methods have not well incorporated personalized feedback mechanisms for enhancing digital citizenship knowledge. Therefore, this study proposed an algorithm that combines concept-effect propagation,…

The visual system can learn statistical regularities and form search habits that guide attention to a region where a target frequently appears. Although regularities in the real world can change over time, little is known about how such changes affect habit learning. Using a location probability learning task, we demonstrated that a constant…

The purpose of this study was to examine the effect of interactive online learning tools on college student learning using flow as the guiding perspective. Study 1 was conducted to test the effect of online interactivity manipulated by dynamic visual learning tools on student's flow experience, level of telepresence, actual performance on tests,…

Humans have an extremely flexible ability to categorize regularities in their environment, in part because of attentional systems that allow them to focus on important perceptual information. In formal theories of categorization, attention is typically modeled with weights that selectively bias the processing of stimulus features. These theories…

Two experiments tested possible explanations for previous research demonstrating lower span of apprehension for learning disabled students. In experiment 1, the length of visual persistence was less for LD subjects, while in experiment 2, the rate of information pick-up was slower for LD subjects. (CL)

Examined possibility that arousability as manifested in sensitization contributes to individual differences in infants' attentional profiles. Sensitization tended to occur more frequently with more complex than with less complex checkerboards. Infants showing sensitization looked longer and did not habituate as readily as infants who showed no…

Two experiments examined the origins of joint visual attention in 6- to 11-month-olds with a training procedure. Results indicated that joint visual attention does not reliably appear prior to 10 months; from about 8 months, a gaze-following response can be learned; and simple learning is not sufficient as the mechanism through which joint…

Tests infants' dual-process performance (a process mediating response decrements called habituation and a state-dependent process mediating response increments called sensitization) on visual habituation-dishabituation tasks. (HOD)

Assesses the impact of the visual complexity of "Sesame Street" segments on preschoolers' visual attention, recall, and recognition. Results indicate that attention and learning are enhanced by (1) visually simple sets in terms of few objects on the screen and (2) low to moderate levels of screen activity. (PD)

Preplays (critical material presented before a televised program) were inserted before three sections of a televised story to determine if they would improve children's attention and comprehension by providing overall plot structure for selecting and integrating important story events. The preplays varied on two orthogonal dimensions: presence or…

A study tested the effects of between-channel redundancy on television news learning. Redundancy, defined as shared information, was proposed as an explanatory variable that considers the relationship between information in three channels: the audio, the nonverbal pictorial, and visual-verbal print channel. It was hypothesized that pictures would…
