Walking Corsi Test (Piccardi et al., 2008)

The Walking Corsi Test (WalCT: Piccardi et al., 2008)

It assesses topographic memory assessesing short and long-term topographic memory in two different conditions with and without landmarks (Piccardi et al 2015). It is a large scale adaptation of the well-known Corsi Test (Corsi, 1975) used to assess visuo-spatial memory in the reaching space. Since its development in 2008, WalCT has been widely used in both clinical practice and experimental settings. Studies with the WalCT were conducted across the lifespan (Piccardi et al 2014a, 2014b, 2015; 2011; Boccia et al 2019) in clinical populations (Piccardi et al 2010; 2011; Bianchini et al 2010; 2014°; 2014b; Boccia et al 2019; Faedda et al 2021; Bartonek et al 2019; 2020; 2021) and in populations with high spatial competence (Verde et al 2014; Piccardi et al 2014).

In clinical practice, it has allowed to demonstrate the dissociation between visuo-spatial memory measured in a reaching space and that measured in visual-navigational space. This has highlighted how memory in the visual-navigational space can represent a marker for cognitive impairment.

The Minefield Task (MFT: Bocchi et al 2020)

The Minefield Task (MFT: Bocchi et al. 2020) aims to assess the ability to plan a route on a

matrix, avoiding some invisible obstacles (false mines) previously seen for a few seconds. It consisted of a walkable white/black chessboard (8 x 8 matrix, 2.5 x 2.5 m) placed on an empty room

An additional tile was placed out of the matrix (1 meter below the chessboard) to indicate the starting position. Two circles with a 10 cm diameter (one red, one green) were used to indicate the starting and the ending positions of each route. Some ‘‘mines’’ of 15 cm diameter made with red and white felt were placed during the observation phase on the chessboard.

The number of mines that could be placed on the matrix ranged from two to nine depending on the trail difficulty. In the first trial, two mines were placed on the chessboard, with the number of mines progressively increasing by one in the successive trials (three mines in the second trial, four in the third and so on). Each trial included two items; therefore, the total number of possible trials was 1.

Complete Visual Mental Imagery Battery (CVMIB: Palermo et al., 2016)

It includes tasks probing the generation, maintenance, inspection, and transformation of visual mental images (the CVMIB is available from the authors upon request at the following email address: cvmibteam@gmail.com).
