Sibling and peer bullying victimization in adolescence: Masculinity, femininity, and the moderating role of sex and popularity.

Introduction: We investigated whether gender-typed traits (masculinity and femininity) contemporaneously predicted self-reported peer victimization, peer-reported peer victimization, and sibling victimization. We also tested the moderating role of sex and popularity.

Methods: A sample of 2782 British pupils aged 11-16 from Central England, UK was screened for bullying involvement and popularity using self-report and peer nominations, and a subsample of 704 (52.

Give me a break! Unavoidable fatigue effects in cognitive pupillometry.

Pupillometry has a rich history in the study of perception and cognition. One perennial challenge is that the magnitude of the task-evoked pupil response diminishes over the course of an experiment, a phenomenon we refer to as a fatigue effect. Reducing fatigue effects may improve sensitivity to task effects and reduce the likelihood of confounds due to systematic physiological changes over time.

Pupillometry reveals cognitive demands of lexical competition during spoken word recognition in young and older adults.

In most contemporary activation-competition frameworks for spoken word recognition, candidate words compete against phonological "neighbors" with similar acoustic properties (e.g., "cap" vs.

Constitutional and somatic rearrangement of chromosome 21 in acute lymphoblastic leukaemia.

Changes in gene dosage are a major driver of cancer, known to be caused by a finite, but increasingly well annotated, repertoire of mutational mechanisms. This can potentially generate correlated copy-number alterations across hundreds of linked genes, as exemplified by the 2% of childhood acute lymphoblastic leukaemia (ALL) with recurrent amplification of megabase regions of chromosome 21 (iAMP21). We used genomic, cytogenetic and transcriptional analysis, coupled with novel bioinformatic approaches, to reconstruct the evolution of iAMP21 ALL.

12p13.33 microdeletion including ELKS/ERC1, a new locus associated with childhood apraxia of speech.

Speech sound disorders are heterogeneous conditions, and sporadic and familial cases have been described. However, monogenic inheritance explains only a small proportion of such disorders, in particular in cases with childhood apraxia of speech (CAS). Deletions of <5 Mb involving the 12p13.
