Neural tuning to print develops when children learn to read and is reflected by a more pronounced left occipito-temporal negativity to orthographic stimuli as compared to non-orthographic false fonts or symbols after around 150-250 ms in their N1, a visual event-related potential (ERP). In adults, initial expertise for a novel script can emerge in…

Episodic memory involves flexible retrieval processes that allow us to link together distinct episodes, make novel inferences across overlapping events, and recombine elements of past experiences when imagining future events. However, the same flexible retrieval and recombination processes that underpin these adaptive functions may also leave…

Great controversy exists on whether associative learning occurs without awareness. In Experiment 1, 31 participants received discrimination training by repeated presentations of two stimulus sequences (S1[subscript A] right arrow S2[subscript A], and S1[subscript B] right arrow S2[subscript B]), S1 being a masked stimulus. S2 were imperative…

This study was designed to compare both levels of performance and relationships between performances on cognitive tests in groups of children and adolescents in Canada and the Philippines with similar educational experience. A battery of eighteen tests, including the Ravens Progressive Matrices (1958), the Science Research Associates Primary…

This paper discusses questions pertinent to a definition of cognitive structure as the knowledge one possesses and the manner in which it is arranged, and considers how to select or devise methods of describing cognitive structure. The main purpose in describing cognitive structure is to see whether differences in memory (or cognitive structure)…

THE RESEARCH REPORTED HERE CONCERNED THE RELATIONSHIP BETWEEN LANGUAGE AND COGNITION IN THE CONTEXT OF THE WHORF HYPOTHESIS ABOUT LANGUAGE AND CULTURE. EXPERIMENTS WERE CARRIED OUT INVESTIGATING THE EFFECT OF SOME LINGUISTIC AND REFERENT DIMENSION VARIABLES ON THE LEARNING OF MINIATURE LINGUISTIC SYSTEMS. A MINIATURE LINGUISTIC SYSTEM (MLS) IS A…

We tracked the evolvement of naming-related cortical dynamics with magnetoencephalography when five normal adults successfully learned names and/or meanings of unfamiliar objects. In all subjects, the learning of new names was associated with pronounced cortical effects. The learning effect was of long latency and emerged as a change of activation…

It was hypothesized that there are significant differences in intellectual patterns between black and white populations which can be demonstrated on the Wechsler Adult Intelligence Scale (WAIS). A one-way analysis of variance was performed on the subjects' scores on the WAIS subtests and the Verbal, Peformance and Full Scale IQ using the ethnic…
