Validation of the Chinese version of Community Assessment of Psychic Experiences (CAPE) in an adolescent general population.

The Community Assessment of Psychic Experiences (CAPE) is a popular 42-item self-report assessment of psychosis proneness (PP) that has been widely-translated. However, there is as yet no validation of CAPE in non-Western languages. Here, we validated a Chinese translation of CAPE ("CAPE-C") in a young Chinese community sample.

Cognitive intermediate phenotype and genetic risk for psychosis.

Intermediate phenotypes (IPs) are defined as measurable liability traits underlying complex phenotypes, posited to be more genetically tractable than the phenotypes themselves. Here we review evidence for cognition as an IP of psychosis, and highlight topical advances in the literature: first, heritability estimation of cognitive abilities using genomewide complex-trait analysis; second, evidence that cognition lies upstream to schizophrenia liability; third, use of polygenic risk scores rather than single genetic variants to examine genetic overlap between cognitive IPs and schizophrenia; and fourth, use of cognitive IPs for schizophrenia risk gene discovery and functional characterization. We end with future directions in using cognitive IPs to study genetic risk of psychosis, including methodological refinements and shifting research focus from identifying IPs to using them.

Psychometric Properties of "Community Assessment of Psychic Experiences": Review and Meta-analyses.

The Community Assessment of Psychic Experiences (CAPE) has been used extensively as a measurement for psychosis proneness in clinical and research settings. However, no prior review and meta-analysis have comprehensively examined psychometric properties (reliability and validity) of CAPE scores across different studies. To study CAPE's internal reliability--ie, how well scale items correlate with one another--111 studies were reviewed.

Linguistic influence on mathematical development is specific rather than pervasive: revisiting the Chinese Number Advantage in Chinese and English children.

The relative linguistic transparency of the Asian counting system has been used to explain Asian students' relative superiority in cross-cultural comparisons of mathematics achievement. To test the validity and extent of linguistic transparency in accounting for mathematical abilities, this study tested Chinese and British primary school children. Children in Hong Kong can learn mathematics using languages with both regular (Chinese) and irregular (English) counting systems, depending on their schools' medium of instruction.
