Neural correlates of error-monitoring and mindset: Back to the drawing board?

The different ways students deal with mistakes is an integral part of mindset theory. While previous error-monitoring studies found supporting neural evidence for mindset-related differences, they may have been confounded by overlapping stimulus processing. We therefore investigated the relationship between mindset and event-related potentials (ERPs) of error-monitoring (response-locked Ne, Pe), with and without overlap correction. In addition, besides behavioral measures of remedial action after errors (post-error slowing and accuracy), we investigated their neural correlates (stimulus-locked N2). Results indicated comparable Ne, but larger Pe amplitudes in fixed-minded students; however, after overlap correction, the Pe results were rendered non-significant. A likely explanation for this overlap was a near-significant effect of mindset on the preceding stimulus P3. Finally, although N2 was larger for trials following errors, mindset was unrelated. The current study shows that the relationship between error-monitoring and mindset is more complex and should be reconsidered. Future studies are advised to explore stimulus processing as well, and if needed, to correct for stimulus overlap. In addition, contextual influences on and individual variation in error-monitoring need more scrutiny, which may contribute to refining mindset theory.

Trauma Exposure in Relation to the Content of Mother-Child Emotional Conversations and Quality of Interaction.

Parent-child conversations contribute to understanding and regulating children's emotions. Similarities and differences in discussed topics, quality of interaction and coherence/elaboration in mother-child conversations about emotional experiences of the child were studied in dyads who had been exposed to interpersonal trauma (N = 213) and non-trauma-exposed dyads (N = 86). Results showed that in conversations about negative emotions, trauma-exposed children more often discussed trauma topics and focused less on relationship topics than non-trauma-exposed children. Trauma-exposed dyads found it more difficult to come up with a story. The most common topics chosen by dyads to discuss for each emotion were mostly similar between trauma-exposed dyads and non-trauma-exposed dyads. Dyads exposed to interpersonal traumatic events showed lower quality of interaction and less coherence/elaboration than dyads who had not experienced traumatic events. Discussion of traumatic topics was associated with lower quality of mother-child interaction and less coherent dialogues. In conclusion, the effect of the trauma is seen at several levels in mother-child interaction: topics, behavior and coherence. A focus on support in developing a secure relationship after trauma may be important for intervention.
