The role of prior knowledge in incremental associative learning: An empirical and computational approach

Publication date: August 2019Source: Journal of Memory and Language, Volume 107Author(s): Oded Bein, Maayan Trzewik, Anat MarilAbstractOur experiences are encoded in relation to existing knowledge, and learning of new information is influenced by what has already been learned. Although learning is often an incremental process spanning multiple repetitions, the influences of prior knowledge have thus far been investigated primarily in one-trial learning. Incremental learning studies have generally not taken prior knowledge influences into consideration. Aiming to fill this gap, we examined the contribution of prior knowledge to incremental learning. Prior knowledge was manipulated using famous and novel faces. Participants viewed repeated pairs of faces: either a famous face paired with a novel face, or a pair of novel faces. Prior knowledge facilitated processing, as evidenced by decreased reaction times, in a task that was unrelated to previous knowledge. This decrease only emerged with repetitions and was maintained throughout the experiment, demonstrating a continuous influence of prior knowledge on learning. Enhanced processing was also related to learning of specific-face information, beyond response learning. Interestingly, decreased reaction times were observed during learning even when participants did not explicitly remember pair-associations in a final memory test. Computational modelling suggests that delayed facilitation may be attributed to prior knowledge, which...

Conclusions: Results of the present study support the interpersonal theory of suicide, which suggests that self-reported thwarted belongingness can foster WD. Clinical implications: Clinicians should consider social dissatisfaction and withdrawal as risk factors for WD and design interventions that foster social skills or meaningful connections.

Authors: Taki S, Maekita T, Sakata M, Fukatsu K, Maeda Y, Iguchi M, Ito H, Kitano M Abstract Continuous duodenal levodopa/carbidopa intestinal gel delivery by a gastrostomy infusion system improves control of Parkinson's disease. The overall complication rates of percutaneous endoscopic gastrojejunostomy were reported to be 41% and 59% for immediate and delayed adverse events, respectively. A 72-year-old woman underwent percutaneous endoscopic gastrojejunostomy using the delivery system noted above. Abdominal pain and vomiting occurred 3 months later. Esophagogastroduodenoscopy showed a longitudinal ulcer extending...
