Effect of cognitive style on time-based prospective memory

Abstract

Field-independent and field-dependent individuals have different reference patterns and cognitive processing preferences. Field-independent individuals tend to rely on internal capabilities and use internal references to process information, while field-dependent individuals mainly rely on external references and focus on external information. Individuals with two cognitive styles have different attention patterns to perform time-based prospective memory (TBPM) tasks, with different effects on their TBPM performance. This study explored the influence of field-independent and field-dependent cognitive styles on TBPM. In Experiment 1, the attention load was manipulated by the difficulty of the ongoing task. The results showed that the field-independent individuals performed better than the field-dependent individuals only under a low-difficulty condition, indicating that the field-independent individuals had advantages in TBPM but were easily affected by the attention load. Experiment 2 further introduced external reminders to provide individuals with more external information and reduce individual attention consumption in internal time information processing to manipulate attention load. The results showed that external cues eliminated the difference between field-independent and field-dependent individuals in TBPM.
