5. 23. Train your brain : updating, transfer, and neural changes

   Author : Erika Dahlin; Lars Nyberg; Anna Stigsdotter Neely; Torkel Klingberg; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; cognitive training; executive functioning; transfer; fMRI; brain system; young adults; elderly; practice; neural correlates; individual differences; Experimental brain research; Experimentell hjärnforskning; Cognitive science; Kognitionsforskning; fysiologi; Physiology;

   Abstract : An initial aim of this thesis was to determine whether training of a specific executive function (updating) produces improvements in performance on trained and transfer tasks, and whether the effects are maintained over time. Neural systems underlying training and transfer effects were also investigated and one question considered is whether transfer depends on general or specific neural overlap between training and transfer tasks.

6. 24. The dynamics of second language learning : a longitudinal and qualitative study of an adult's learning of Swedish

   Author : Nils Granberg; Umeå universitet; []
   Keywords : HUMANIORA; HUMANITIES; second language learning; second language acquisition; individual differences; attitude; motivation; learning strategies; communication strategies; identity; liminality; case study; Grounded Theory; hermeneutic; qualitative; holistic; longitudinal; Swedish;

   Abstract : An often discussed issue in the field of second language learning is the influence and importance of individual differences, IDs, such as motivation, personality, previous learning experiences and learning strategies. It has been claimed that IDs form a complex system in the learner, but little consensus has been reached as regards definitions of constructs or their relative importance. READ MORE

7. 25. Validity considerations in the study of language learning aptitude

   Author : Lars Bokander; Kristina Danielsson; Jan H. Hulstijn; Linnéuniversitetet; []
   Keywords : HUMANIORA; HUMANITIES; language aptitude; language testing; individual differences; Swedish vocabulary; test validation; Lingvistik; Linguistics;

   Abstract : Language learning aptitude is a hypothesized psychological construct that has been used to explain differences in how fast and how well people can acquire a second language (L2). It is generally assumed that language learning aptitude is a multidimensional phenomenon, meaning that it consists of sub-constructs that are not necessarily interrelated. READ MORE
