Abstract
Fast mapping as a way for adults to learn new lexical items is a hot topic and only a limited number of studies have connected fast mapping to brain imaging (see Merhav, Karni, & Gilboa, 2015). The present study aims to compare and contrast explicit encoding with fast mapping of new vocabulary items in adult healthy Swedish native speakers (N=17, NFEMALE=7) as well as connect these behavioural experimental results with the white matter using diffusion tensor imaging. The present experimental setup is based on Coutanche and Thompson-Schill’s (2014) study and it applies a cross sectional design. After the ethical approval of the Swedish Ethical Review board, participants were asked to participate in a computerised experiment that involved... (More)
Fast mapping as a way for adults to learn new lexical items is a hot topic and only a limited number of studies have connected fast mapping to brain imaging (see Merhav, Karni, & Gilboa, 2015). The present study aims to compare and contrast explicit encoding with fast mapping of new vocabulary items in adult healthy Swedish native speakers (N=17, NFEMALE=7) as well as connect these behavioural experimental results with the white matter using diffusion tensor imaging. The present experimental setup is based on Coutanche and Thompson-Schill’s (2014) study and it applies a cross sectional design. After the ethical approval of the Swedish Ethical Review board, participants were asked to participate in a computerised experiment that involved fast mapping and explicit encoding phases as well as word learning ability, analytical and cognitive ability testing, and a pencil-paper based perceived foreign language proficiency test. Participants also took part in a diffusion tensor imaging scanning immediately after the behavioural experiments. Results revealed moderate correlation between fast mapping and explicit encoding, and strong correlation between the word learning ability test and explicit encoding. However, no strong correlation could be established between fast mapping and the word learning ability test. Unfortunately, no significant results could be found between white matter and explicit encoding or fast mapping, the latter ones being predictors at the significance level of p≤ .05. The behavioural findings are consistent with Warren and Duff (2014) and Greve, Cooper & Henson (2014) who propose that explicit encoding and fast mapping are not entirely separate processes. (Less)
