Subjectivity of Mental Imagery Reporting
The study heavily relies on participant reporting for mental imagery, which is subjective and can be influenced by various factors.
Limited Generalizability of Musical Stimuli
While the study tested different languages, the stimuli were limited to folk music and may not generalize to other genres.
Abstraction in Stable Diffusion Visualization
The stable diffusion visualization, while providing an intuitive representation, adds a layer of abstraction and interpretation that may not fully capture the nuances of imagined content.
Potential Uncontrolled Factors
Although the study controlled for some factors (e.g., vocals, language comprehension), there might be other uncontrolled factors (e.g., prior experiences, personal preferences, current emotional state, specific cultural context) influencing mental imagery.
