Journal ArticleDOI
Dyslexia Heterogeneity: Cognitive Profiling of Portuguese Children with Dyslexia.

TL;DR: In this paper, the authors used hierarchical cluster analysis to group participants according to their phonological awareness, rapid automatized naming, verbal short-term memory, vocabulary, and nonverbal intelligence abilities.
Journal ArticleDOI
Instruction-specific brain activations during episodic encoding. a generalized level of processing effect.
TL;DR: The levels-of-processing (LOP) effect using visual material in a behavioral and a corresponding PET study is investigated and it is suggested that the anterior medial superior frontal region is related to aspects of self-referential semantic processing and the inferior parts of the anterior cingulate as well as the medial orbitofrontal cortex are related to affective processing.
Artificial grammar learning and neural networks
TL;DR: It is concluded that statistical frequency-based and rule-based acquisition procedures can be viewed as complementary perspectives on grammar learning, and more generally, that classical cognitive models can be views as a special case of a dynamical systems perspective on information processing.
Journal ArticleDOI
Implicit structured sequence learning: An fMRI study of the structural mere-exposure effect
TL;DR: This paper investigated the effect of 5 days of implicit acquisition on preference classification by means of an artificial grammar learning (AGL) paradigm based on the structural mere-exposure effect and preference classification using a simple right-linear unification grammar.
Journal ArticleDOI
Semantic unification modulates N400 and BOLD signal change in the brain: A simultaneous EEG-fMRI study

TL;DR: Light is shed on how to integrate trial-level variation in language comprehension by employing the EEG-fMRI integrated analyses, which are among the first to shed light on how the brain processes involved in semantic unification are integrated.
