Abstract
When faced with reminders, especially intrusive ones, forgetting is central to our everyday life and mental health. Anderson and Green (2001) constructed the Think/No-Think (TNT) to investigate people's ability to consciously suppress material, resulting in suppression-induced forgetting (SIF). During the TNT task, individuals first learn word pairs, e.g., Roach – Ordeal. Then they are presented with the hint word (e.g., Roach) and instructed not to think about the response word (e.g., Ordeal) by actively trying to avoid thinking about it. SIF is tested in two conditions, one testing for the recall of the response word when given the hint word (Same Probe, SP), the other using a category word related to the response word to test for cue independent forgetting (Independent Probe, IP). The current study aimed to investigate SIF in TNT and its proposed connection to executive and thought control processes by assessing the connection between the SIF scores, a self-report executive function questionnaire (Webexec), and a self-report thought control ability questionnaire (TCAQ). The final sample consisted of 150 participants who partook in an online administered TNT task. The data analysis showed no statistically significant results for SIF in TNT, as well as no statistically significant effects for executive control on SIF. However, results for thought control ability on SIF in IP showed a weak positive statistically significant correlation. Further research is necessary to evaluate the robustness of SIF and its connection to executive control, as the current results should be considered in light of the study’s online administration.
