Translation research is undergoing a shift as scholars re-evaluate how translators process language and meaning. A recent review of studies applying think-aloud protocols (TAPs) to translation research has highlighted the strengths and limitations of this method, suggesting that while it offers valuable insights into the cognitive aspects of translation, its application remains inconsistent and sometimes lacks depth. The review was published in the journal ISPCE Bulletin.
TAPs require translators to verbalise their thoughts while translating, allowing researchers to observe decision-making processes in real time. This approach has been widely adopted in both China and Western countries, though the focus of research varies. In China, studies primarily examine translation strategies and units, often involving student translators. In contrast, overseas studies extend to cognitive processes, post-editing, and the role of translation technology, offering a broader perspective on how translators work.
Hongfei Xiao, a researcher from Jiangxi Normal University Science and Technology College in China, said: “Domestic research mainly explores translation strategies and units, whereas overseas studies extend to cognitive load, problem-solving, and post-editing. However, both research streams face challenges such as inconsistent experimental design, insufficient cognitive depth, and limited participant diversity.”
One of the main challenges identified in the review is the inconsistency in research design. The number of participants varies significantly across studies, and in many cases, sample sizes are small. While qualitative research does not require large samples, the lack of uniformity raises questions about the reliability of findings. Another issue is the selection of texts used in experiments. Many studies fail to consider the complexity of texts and how different genres may impact translation strategies. Without standardised criteria for text difficulty, comparing results across studies becomes problematic.
A significant gap in research is the limited exploration of memory and cognitive load in translation. Although TAPs provide a window into conscious decision-making, they do not fully capture the subconscious aspects of translation. Xiao pointed out that “Chinese studies predominantly investigate translation techniques among learners, but they often overlook deeper cognitive factors such as memory and attention. Overseas research, though broader in scope, also struggles with standardising research design, text difficulty assessment, and translation quality evaluation.”
Another area for improvement is the practical application of research findings. While many studies identify translation difficulties, few offer solutions or test interventions to enhance translator training. “Many TAP studies focus on problem identification rather than developing practical solutions for translation training,” Xiao noted, underscoring the need for research to move beyond observation and experiment with ways to improve translation accuracy and efficiency.
There is also a notable difference in participant diversity between domestic and international studies. Chinese studies tend to rely heavily on English major students, while overseas studies include professional and non-professional translators, as well as participants from different language backgrounds. This diversity enhances the generalisability of findings and provides a more complete picture of translation processes. “Participant selection is often limited, with domestic studies relying heavily on English majors and overseas research incorporating a wider but still unbalanced participant pool. These limitations hinder the full potential of TAPs in revealing how translation processes function across different contexts,” Xiao added.
The review highlights the need for greater methodological rigour in translation research. Standardising participant selection, text complexity assessment, and research objectives could enhance the reliability of findings. Additionally, combining TAPs with other cognitive research tools may help address existing gaps in understanding how translators think and make decisions. Xiao suggested that “future development should focus on integrating quantitative methods with TAP research to enhance analytical precision. A more systematic approach to experimental design, including well-defined research objectives and controlled variables, is essential.”
As the field of translation continues to evolve, the role of technology and cognitive science in understanding translation processes will likely expand. Xiao emphasised the importance of this development, stating, “With the boosting of AI tools, TAP studies should also be extended to areas like AI-assisted translation to understand how translators interact with technological tools. Additionally, more attention should be given to text selection and difficulty assessment using cognitive psychology frameworks. By addressing these gaps, future TAP research can deepen its impact on translation studies and bridge the divide between theoretical insights and practical applications.”
