Paranormal believers are more quickly and less accurate in rejecting the presence of the target in conjunction visual search compared to skeptics

Recent studies have shown that paranormal believers may exhibit cognitive dysfunctions, yet their performance in conjunction with visual search has not been understood. To address this issue, we examined the performance of both paranormal believers and skeptics in a conjunction visual search task, paying particular attention to their search time and accuracy across different set sizes in both target-present (TP) and target-absent (TA) trials. In our study, believers demonstrated a tendency toward speed but also displayed carelessness compared to skeptics when rejecting the presence of the target. Conversely, skeptics exhibited slower search times but demonstrated greater accuracy both in rejecting the presence of the target and in finding it. Overall, our findings suggest that believers were quicker and less accurate in rejecting the presence of the target in conjunction visual search compared to skeptics, highlighting potential differences in cognitive processing between skeptics and believers. Significant statementOur study investigates the performance of paranormal believers and skeptics in conjunction with visual search tasks, shedding light on potential differences in cognitive processing between the two groups. While believers demonstrate faster search times, they also display greater carelessness compared to skeptics when rejecting the targets presence. In contrast, skeptics exhibit slower search times but higher accuracy in both rejecting and finding the target. These findings underscore the importance of considering individual belief systems in understanding cognitive performance in conjunction with visual tasks.

Target location and age-related dynamics affect conjunction visual search dynamics

AbstractPrevious research has demonstrated that visual search is influenced by environmental factors, but the effects of specific variables, such as target distance from the visual field center and age, are not well understood. To address this issue, we aim to investigate their impact on visual search task. Participants engaged in target-present and target-absent trials, revealing distinct patterns in search times. Behavioral data and drift-diffusion modeling (DDM) showed that increasing the targets distance from the center of the visual field significantly reduces search efficiency. Additionally, age negatively impacts search performance, with older individuals exhibiting reduced efficiency. This comprehensive examination contributes to understanding cognitive mechanisms in visual processing. These findings highlight the importance of considering spatial and age-related factors in visual search tasks.
