By building a schlieren optical system, the visualization of a 40 KHz sound wave is realized. By using the schlieren system, the demonstration of acoustic reflection, interference and diffraction can be easily realized. At the same time, the visual acoustic field provides another simple way for the measurement of sound velocity. In this paper, the…

Twenty-three college students participated in two studies evaluating an application designed to measure stimulus overselectivity in pictures depicting facial affect. We analyzed whether this application worked as designed by evaluating whether it could provide a robust analysis of the types of errors users make (e.g., by matching by the top…

The research studied the perception of Deaf college students on the use of a multimodal approach in teaching literacy to them. The research used a case study design to present five Deaf college students who underwent multimodal intervention sessions. The study primarily used qualitative data, supported by quantitative data from instrument scores.…

This study investigated the development of rapid visual object categorization. N = 20 adults (Experiment 1), N = 21 five to six-year-old children (Experiment 2), and N = 140 four-, seven-, and eleven-month-old infants (Experiment 3; all predominantly White, 81 females, data collected in 2013-2020) participated in a fast periodic visual stimulation…

The number-line task has been extensively used to study the mental representation of numbers in children. However, studies suggest that proportional reasoning provides a better account of children's performance. Ninety 4- to 6-year-olds were given a number-line task with symbolic numbers, with clustered dot arrays that resembled a perceptual…

In two experiments, participants tracked the identity and location of moving words. The task bears resemblance to one performed by air traffic controllers who track multiple moving aircraft, where they are identified with relatively complex alphanumeric call signs. In Experiment 1, stimulus familiarity was manipulated by comparing the tracking of…

We examined emergent tact control following stimulus pairing, using 2 different stimulus presentation arrangements. In the word-first condition, presentation of the auditory stimulus preceded the visual stimulus, and in the image-first condition, the visual stimulus preceded the auditory stimulus. Eight children (2-5 years old) participated. In…

Two visual world experiments investigated the activation of semantically related concepts during the processing of environmental sounds and spoken words. Participants heard environmental sounds such as barking or spoken words such as "puppy" while viewing visual arrays with objects such as a bone (semantically related competitor) and…

Prior research suggests that visual features of the classroom environment (e.g., charts and posters) are potential sources of distraction hindering children's ability to maintain attention to instructional activities and reducing learning gains in a laboratory classroom. However, prior research only examined short-term exposure to elements of…

The effects of rewards on executive function (EF) reflect bidirectional interactions among motivational and executive systems that vary with age and temperament. However, methodological limitations hinder understanding of the precise influences of incentives on early EF, including the role of reward sensitivity. In this within-subjects study,…

Discourse-based interviews (DBIs) uncover tacit knowledge within written composing processes. Existing visual research methodologies offer tools for a necessary expansion of DBI to the study of tacit knowledge in visual and multimodal texts. This article outlines a feminist application of eye tracking as a visual research method used in…

Purpose: Armed with the theory of embodied cognition proposing tight interactions between perception, motor, and cognition, this study aimed to test the hypothesis that speech rate-altered Mandarin lexical tone perception in quiet and noisy environments could be affected by the bodily dynamic cross-modal information. Method: Fifty-three adult…

Considering the mixed nature of reports of flexibility difficulties in autism, we hypothesized that a task that more closely resembles the challenges faced in real life would help to assess these difficulties. Autistic and typically developing adults performed an online Emotional Shifting Task, involving non-explicit unpredictable shifts of…

COVID-19 e-books have emerged as means for communicating information about coronavirus and the resulting disease to children during the pandemic. This material is multimodal, with images forming the most prevalent and crucial semiotic mode. Except for representational and compositional meaning, an image realises interpersonal meanings. The degree…

Relational thinking and dealing with variables are two essential aspects of algebraic thinking. Relational thinking means viewing mathematical expressions and equations as a whole rather than as individual computing processes. It is characterized by using relationships between mathematical objects, and refers to the relations of equality and…
