The comparative study of infant development and animal cognition brings to cognitive science the promise of insights into the nature and origins of cognitive skills. In this article, I review a recent wave of comparative studies conducted with similar methodologies and similar theoretical frameworks on how two core components of human cognition--object(More)
This paper reports on email classification and filtering, more specifically on spam versus ham and phishing versus spam classification, based on content features. We test the validity of several novel statistical feature extraction methods. The methods rely on dimensionality reduction in order to retain the most informative and discriminative features. We(More)
This article presents a tentatively "balanced" view (i.e., midway between lean and rich interpretations) of pointing behavior in infants and apes, based upon the notion of intentional reading of behavior without simultaneous attribution of unobservable mental states. This can account for the complexity of infant pointing without attributing multilayered(More)
OBJECTIVE To evaluate the safety and tolerability of olanzapine in the treatment of elderly patients with schizophrenia. METHODS A total of 135 outpatients with schizophrenia > or =60 years of age were treated with olanzapine (n = 105) or another antipsychotic (n = 30) and followed up for 6 months. Safety measures included the recording of spontaneous(More)
BACKGROUND Conventional antipsychotics although effective in treating acute psychotic and behavioural symptoms are subject to certain limitations due to the high incidence of side effects associated, mainly extrapyramidal symptoms (EPS), and insufficient response shown in some cases. EPS are a major factor in neuroleptic non compliance and high relapse(More)
OBJECTIVE To assess the safety and effectiveness of olanzapine compared to typical antipsychotics in the treatment of first-episode schizophrenics in acute psychiatric inpatient wards. METHODS Data were collected from a prospective, comparative, nonrandomized, open, observational study of 904 inpatients with schizophrenia. One hundred and fifty-eight(More)
BACKGROUND This study investigated safety and effectiveness of olanzapine in monotherapy compared with conventional antipsychotics in treatment of acute inpatients with schizophrenia. METHOD This was a prospective, comparative, nonrandomized, open-label, multisite, observational study of Spanish inpatients with an acute episode of schizophrenia. Data(More)
We examined whether the movement involved in a pointing gesture, depicted using point-light displays, is sufficient to cue attention in typically developing children (TD) and children with autism spectrum disorder (ASD) (aged 8-11 years). Using a Posner-type paradigm, a centrally located display indicated the location of a forthcoming target on 80% of(More)
