Short-term and long-term within-person variability in performance: an integrative model.

Previous research on within-person variability in performance has largely examined short-term fluctuations and long-term changes in performance separately. The present study proposes a model-based on the cognitive-affective personality system meta--theory (Mischel & Shoda, 1995)--that integrates short-term and long-term performance variability within the 1 framework. Key propositions of the model include that short-term performance fluctuations are contingent on variability in situational cues and that situational cue-performance contingencies change over time.

Association between a polymorphism of the vasopressin 1B receptor gene and aggression in children.

Objectives: The involvement of arginine-vasopressin (AVP) in animal and human aggression has been well established in the literature. Recent research has shown an association between the minor allele (C) of single-nucleotide polymorphism rs35369693 located on the AVP 1B receptor gene and childhood aggression.

Materials And Methods: The present study sought to replicate the association between rs35369693 and aggression using a sample of clinically referred children (N=141) with behavioural problems.
