Attentional responses in toddlers: A protocol for assessing the impact of a robotic animated animal and a real dog

2025 , Zapata, Mireya , Ramos Galarza, Carlos , Kevin Valencia-Aragón , Jorge Alvarez-Tello , Maheshkumar Baladaniya

Attentional processes in toddlers are characterized by a state of alertness in which they focus their waking state for short periods. It is essential to develop assessment and attention stimulation protocols from an early age to improve this cognitive function and detect possible deficits in the early stages of cognitive development. Methods: This protocol-based article presents a technological approach to assessing the impact of two animated stimuli on toddlers’ attention. The protocol involves presenting a robotic and a real dog to evaluate attentional activation in early development. This dual-stimulus framework may also inform therapeutic and educational programs aimed at fostering cognitive growth in early childhood. Discussion: This protocol contributes to assessing physiological attentional responses in toddlers, offering insights into attention evaluation and stimulation during early cognitive development. By incorporating both a robotic and a live dog, it enables the exploration of individual differences in attentional engagement and identifies which stimulus elicits a stronger response.

Experimental Evaluation of EMKEY: An Assistive Technology for People with Upper Limb Disabilities

2023 , Zapata, Mireya , Kevin Valencia-Aragón , Ramos Galarza, Carlos

Assistive technology can help people with disabilities to use computers more effectively and can enable them to access the same information and resources as people without disabilities. To obtain more insight into the factors that can bring about the design of an Emulator of Mouse and Keyboard (EMKEY) to higher levels of user satisfaction, an experimental study was conducted in order to analyse its effectiveness and efficiency. The experimental study involved 27 participants (Mage = 20.81, SD = 1.14) who performed three experimental games under different conditions (using the mouse and using EMKEY with head movements and voice commands). According to the results, the use of EMKEY allowed for the successful performance of tasks such as matching stimuli (F(2,78) = 2.39, p = 0.10, η2 = 0.06). However, the execution times of a task were found to be higher when using the emulator to drag an object on the screen (t(52,1) = −18.45, p ≤ 0.001, d = 9.60). These results indicate the effectiveness of technological development for people with upper limb disabilities; however, there is room for improvement in terms of efficiency. The findings are discussed in relation to previous research and are based on future studies aimed at improving the operation of the EMKEY emulator.
