Abstract Task adaptation, characterized by a progressive increase in speed throughout experimental trials, has been extensively observed across various paradigms. Yet, the underlying mechanisms driving this phenomenon remain unclear. According to learning-based explanation, participants are implicitly learning, becoming more proficient over time. Conversely, motivation-based view suggests that participants’ drive wanes gradually, prompting quicker pace and reduced task engagement. These explanations offer distinct predictions. The anticipates not only accelerated but also improved response accuracy. In contrast, assumes lose their focus, increases, accuracy tends decline. present study tests these implications series of six self-paced reading experiments investigating interplay between reaction times, immediate recall, trial order. Robust learning effects documented. Participants read progressively faster during experiments, they get better responding. Moreover, an analysis recall reveals systematic differences different types information, with nouns yielding substantially higher than adjectives. findings explained through attentional mechanisms: prolonged processing specific words correlates recall. Furthermore, differential patterns modulated task’s question structure, adjectives recalled effectively proportion adjective-targeting questions. This underscores strategic allocation attention sentence components deemed crucial for performance, highlighting dynamic motivation, adaptation.
