Database of word-level statistics for Mandarin Chinese (DoWLS-MAN).

In this article we present the Database of Word-Level Statistics for Mandarin Chinese (DoWLS-MAN). The database addresses the lack of agreement in phonological syllable segmentation specific to Mandarin by offering phonological features for each lexical item according to 16 schematic representations of the syllable (8 with tone and 8 without tone). Those lexical statistics that differ per phonological word and nonword due to changes in syllable segmentation are of the variant category and include subtitle lexical frequency, phonological neighborhood density measures, homophone density, and network science measures.

Phonological network fluency identifies phonological restructuring through mental search.

We investigated network principles underlying mental search through a novel phonological verbal fluency task. Post exclusion, 95 native-language Mandarin speakers produced as many items that differed by a single lexical tone as possible within one minute. Their verbal productions were assessed according to several novel graded fluency measures, and network science measures that accounted for the structure, cohesion and interconnectedness of lexical items.

Premorbid IQ subgroups in first episode non affective psychosis patients: Long-term sex differences in function and neurocognition.

Background: Low IQ has been associated with schizophrenia, even to the point of being posited as a possible causal factor for psychosis. However, individuals with normal and high IQ also develop psychotic illnesses. The aim of this study was to characterize premorbid IQ subgroups at first episode of psychosis (FEP).

Incidence and risk factors of acute akathisia in 493 individuals with first episode non-affective psychosis: a 6-week randomised study of antipsychotic treatment.

Introduction: Acute akathisia is a neuropsychiatric syndrome with a negative effect on illness outcome. Its incidence in patients treated with antipsychotics has shown to be highly variable across studies.

Objectives: Our goals were to investigate prevalence, risk factors for the development of acute akathisia, and differences in incidence between antipsychotics in a sample of 493 first episode non-affective psychosis patients.
