Traditional studies of cognitive ability have examined the component processes and factor structure of ability tests. Theoretical and empirical studies of non-cognitive dimensions of personality have examined how individual differences in personality interact with situational stressors to affect efficient cognitive performance.

Many animal parents invest heavily to ensure offspring survival, yet some eventually consume some or all of their very own young. This so-called filial cannibalism is known from a wide range of taxa, but its adaptive benefit remains largely unclear. The extent to which parents cannibalize their broods varies substantially not only between species, but also between individuals, indicating that i...

The goals of the current study were to use specific measures of affective lability and neuroticism to examine the nomological network surrounding both constructs and to test the degree to which a measure of general personality can account for variability in affective lability. Using a psychiatric outpatient sample (n=48), we assessed personality disorder (PD) symptoms, personality, and level of...

Previous results suggest that both cortisol mobilization and the error-related negativity (ERN/Ne) reflect goal engagement, i.e. the mobilization and allocation of attentional and physiological resources. Personality measures of negative affectivity have been associated both to high cortisol levels and large ERN/Ne amplitudes. However, measures of positive social adaptation and agreeableness ha...

Several recent studies have explored various aspects of animal personality and their ecological consequences. However, the processes responsible for the maintenance of personality variability within a population are still largely unknown. We have recently demonstrated that social personality traits exist in the common lizard (Lacerta vivipara) and that the variation in sociability provides an e...

This study investigated the utility of the MMPI-2-based Personality Psychopathology Five (PSY-5) scales (Harkness, McNulty, & Ben-Porath, 1995) in the outcome prediction of behaviorally oriented chronic-pain treatment. The PSY-5 is a dimensional descriptive system for personality and its disorders. The sample consisted of 120 consecutive chronic-back-pain patients who followed a 4-week multimod...
