Abstract

Prior research has shown that, compared to a negative mood, a positive mood facilitates spreading activation within semantic memory in the first language. Yet, little is still known about neurocognitive mechanisms underlying mood effects on semantic processes in the foreign language. Here, we show that a positive mood enhances accessibility of unrelated concepts within semantic memory in the first but not the foreign language. Highly proficient Polish–English bilingual women were induced into positive and negative mood states with animated films and made semantic relatedness judgements about closely related, weakly related, and unrelated prime–target pairs in their first and foreign languages. Mean N400 responses were analysed as neural markers of spreading activation within semantic memory. Our results revealed reduced N400 responses to unrelated word pairs under a positive compared to a negative mood only in the first language. Critically, no mood-driven effects emerged for the foreign language. These findings provide novel evidence that a positive mood broadens spreading activation within semantic memory only in the first language context, making distant concepts more accessible. Critically, they also highlight mood-independent responding when bilinguals operate in their foreign language.

The paper's code and data availability statement is in the Data section.

Tracing map

Proposed by the machine: these links were found in the paper and verified at the source, without human review. The map will receive a Zenodo DOI once one of the paper's authors has validated it with their ORCID.

What the map holds:

  • 1 repository of the authors' code, each at its verified commit, with its license and how the link was found in the paper;
  • 9 scripts, each with its path and the digest of its content;
  • 7 matches between paragraphs of the paper and lines of the code (method lexical-v1);
  • neither the text of the paper nor the code itself.

Its JSON (tracing-map.json) is deposited on Zenodo with its DOI once the map is validated.

Data

No dataset and no data link were found in the paper.

Data Availability

Pre-processed data, experimental stimuli, model specifications, as well as R and Matlab scripts are publicly available on the Open Science Framework at https://doi.org/10.17605/OSF.IO/NQ4VZ.
