Training in new forms of human-AI interaction improves complex working memory and switching skills of language professionals

AI-related technologies used in the language industry, including automatic speech recognition (ASR) and machine translation (MT), are designed to improve human efficiency. However, humans are still in the loop for accuracy and quality, creating a working environment based on Human-AI Interaction (HAII). Very little is known about these newly-created working environments and their effects on cognition. The present study focused on a novel practice, interlingual respeaking (IRSP), where real-time subtitles in another language are created through the interaction between a human and ASR software. To this end, we set up an experiment that included a purpose-made training course on IRSP over 5 weeks, investigating its effects on cognition, and focusing on executive functioning (EF) and working memory (WM). We compared the cognitive performance of 51 language professionals before and after the course. Our variables were reading span (a complex WM measure), switching skills, and sustained attention. IRSP training course improved complex WM and switching skills but not sustained attention. However, the participants were slower after the training, indicating increased vigilance with the sustained attention tasks. Finally, complex WM was confirmed as the primary competence in IRSP. The reasons and implications of these findings will be discussed.

The relationship between executive functions and naturalistic use of screen-based activities in children

Engagement in interactive game-playing and passive TV watching has become an integral part of young children's routines. While there is a consensus regarding the harmful effect of long passive TV viewing on child development, the influence of interactive game playing is much less clear. This study seeks to specifically explore the association between passive TV watching and interactive-game playing, to executive functions (EF) in typically developing children in their natural environment. A convenience sample of 194 Israeli children (aged 5-7 years) was recruited for our cross-sectional study. Parents provided information on the average daily time their children spent watching TV and playing interactive games. In addition, parents fulfilled the Behavior Rating Inventory of Executive Function (BRIEF) to assess everyday executive skills in natural settings. Our findings revealed significant correlations between TV viewing and poor EF in five out of eight subscales of BRIEF, in addition to the indexes and the global executive composite (p < 0.05). However, the time spent on playing interactive games was not correlated with any of the BRIEF's subscales except one. Moreover, longer time spent watching TV was found to be a significant predictor of low EF among children (F(1,189) = 8.37; p = .004, R² = 3.7%). The current study results show that passive viewing led to worse EF performance than active digital gaming. As a consequence, our study supports previous professional recommendations to limit passive TV viewing.
