A series of experiments will utilize transcranial direct current stimulation (tDCS) as a non-invasive technique for momentarily altering brain function, and the Deese-Roediger-McDermott (DRM) experimental procedure will be used for the controlled analysis of the semantic relationships between the elements of the lists under study and the mechanisms underlying semantic distortions in memory. Two series of empirical studies will be conducted. First, a normative study will be carried out to expand the existing free association database, with the goal of providing suitable semantic materials for the memory experiments. Using the lexical information contained in this database, and data available in other existing databases for Spanish, it will be possible to derive indicators such as resonance, connectivity, associative strength, etc., all of which are important correlates of the effects expected to be analyzed in the planned experiments. At the same time, the collected data, when added to those already available, will create the largest database of its kind to date for any language. Secondly, experiments will be conducted under controlled laboratory conditions to investigate the role of the anterior tract lattice (ATL) as a hub for semantic integration and the procedural stage (encoding or retrieval) in which this integration takes place. To this end, stimulation procedures will be used in specific and relevant areas of both the left and right hemispheres. The proposal is structured around a presentation of the theoretical framework, the current state of knowledge in this field, and the research findings that underpin the experimental plan. And each of the six proposed experiments is presented characterized in detail with regard to the hypotheses, methodological aspects and expected results.

In a set of experiments, transcranial direct current stimulation (tDCS) will be used as a noninvasive technique to temporarily alter brain function, and the Deese-Roediger-McDermott (DRM) experimental paradigm as a procedure for the controlled analysis of the semantic relations established among the words in to-be-studied lists and the underlying mechanisms of semantically-related memory distortions. There will be two series of empirical studies. Firstly, there will be a normative study aimed at increasing the already available free-association database, with the goal of having access to the appropriate semantic materials in the memory experiments. With the lexical information in this database, together with data available in other existing databases for Spanish, it will be possible to obtain indicators such as resonance, connectivity, associative strength, etc., all of them important for understanding the effects that are expected to be analyzed in the planned experiments. At the same time, the collected data, when added to the data already available, will allow researchers to gain access to the largest database of this type for any language. Secondly, experiments will be conducted under controlled laboratory conditions, aimed at examining the role of the ATL as a hub for semantic integration, and the processual stage (encoding, retrieval, both) at which this integration takes place. To that end, stimulation procedures will be applied to relevant selected temporal areas, both in the left and in the right hemispheres. The proposal is articulated on the basis of a presentation of theoretical foundations, the state of the art in the field, and recent empirical findings, all of the supporting a concrete experimental plan. And each of the six planned experiments is described in detail regarding hypotheses, methodological aspects, and expected results.
