RESUMO:
Perceptual decision-making is a cognitive process in which an individual makes a perceptual choice based on available sensory information. This process is fundamental to the interaction of human and non-human animals with their environment. Several studies have been carried out to investigate the factors that influence and the mechanisms underlying this processing. However, most of these works focus on situations where only one stimulus is presented for the observer to make a decision. Recently, interest in how these processes occur when participants need to integrate information from a set of events has increased. In these works, a sequence of stimuli is presented to participants with a specific presentation rate, and participants are asked to judge some characteristic of the series as a whole. Although there is a difference in the rate of presentation between different studies (e.g., 1.5 Hz and 5 Hz), no study has systematically investigated the influence of this rate on participants' performance. However, understanding how different rhythms can influence performance in this task is fundamental to understanding the mechanisms underlying this processing. In the present work, we performed five experiments (four behavioral and one with concomitant EEG acquisition) to investigate how different presentation rates can modulate performance and the strategy adopted by participants in sensory integration tasks. On the one hand, our findings suggest that the presentation rate does not modulate participants' performance. On the other hand, the strategy used by the participants, such as which stimuli in the sequence most influence the final response, is modulated by these rates. The weight given to stimuli later in the series appears to increase when slower presentation rates are used. EEG results suggest that a similar mechanism is involved in the presence of these different rates.
