The update of semantic memories in amnestic mild cognitive impairment

It is still controversial to what extent neocortical consolidated memories are susceptible of change by processes of reconsolidation and transformation throughout experience, and whether the medial temporal lobes are necessary for this update of semantic consolidated memories, as they are for episodic remembering. We hypothesize that patients with amnestic mild cognitive impairment (aMCI) who have deficits in episodic memory may also have difficulties in updating information on added new features of objects. Sixteen participants with aMCI and 20 healthy control participants performed a semantic word-to-picture task, in which they were asked to identify as belonging to a given semantic category NEW objects, that have incorporated novel features, as well as OLD items, semantically and visually SIMILAR items and UNRELATED items. Patients with aMCI made a greater percentage of errors than healthy controls. Participants globally made greater percentages of errors in difficult types of items, namely NEW and SIMILAR, as compared to easier ones, OLD and UNRELATED. Importantly, an item by diagnostic group interaction effect was observed, and post hoc analysis showed that patients with aMCI made a higher percentage of errors than controls in NEW items only. In conclusion, patients with aMCI had a particular difficulty in identifying the NEW items of the word-to-picture task as compared to the control participants, supporting the concept of a flexible and dynamic conceptual knowledge system, involving the update of semantic memories and the integration of new attributes in a constant transformation process, which is impaired in these patients.

Dialogical Temporal Chair Technique

ABSTRACT

The Dialogical Temporal Chair Technique (DTCT) is a method based on Hermans’s dialogical self theory combined with Gestalt and cognitive–behavioural therapeutic techniques. The Dialogical Temporal Chair Technique is a method of activating temporal voices. Three chairs symbolising the past, present and future are used to help subjects create a temporal dialogue. Participants are asked to take a specific I-position and to construct a temporal self-dialogue by changing chair (and hence I-position). The DTCT can be used to solve undefined problems or to explore new ways of thinking, but it may also be used to review important life decisions or enable integration of, or detachment from, ambivalent feelings and attitudes.
