Deglaciation of the Reisa Valley, Northern Norway, and Studies of Glacial Deposits and Dispersal Processes

Durante el retroceso glacial en el area del Valle de Reisa, los principales valles estuvieron ocupados por glaciares marginales que descendían hacia los fiordos. Se han podido detectar cuatro momentos separados de avance o estancamiento de los hielos, marcados por las morrenas marginales correspondientes a acumulaciones del frente glacial. Las morrenas más antiguas, morrenas de Reisatjord, son correlacionables con las morrenas de Ra del Dryas reciente. Las morrenas más jóvenes son de edad Preboreal, 9900-9800 B.P., 9700-9500 B.P. y 9400 $ 250 B.P. respectivamente. Posteriormente el retroceso glacial se caracterizó por los efectos de una gran actividad fluvioglacial. A lo largo del límite entre Finlandia y Noruega, al W del Valle de Reisa, el drenaje del agua de fusión estuvo dirigido por el hielo hacia el Este, más o menos transversalmente a la dirección Norte del movimiento del hielo. Una serie de canales de desagüe cmzaban las divisorias. Los estudios realizados sobre sedimentos de estos depósitos proglaciales muestran una génesis y procedencia complejos. Las composiciones litológica y geoquímica son distintas, generalmente, de la:; de los tills. La composición del till presenta también variaciones verticales. La parte más profunda del till, en contacto con la roca, generalmente es de procedencia local. En las regiones interiores en la parte alta del till predomina el material transportado distancias superiores a los 5 Km. en la parte central de la cuenca de drenaje de Reisa el recubrimiento de till es más delgado y los depósitos glaciales tienen un origen más local. El till sólo contiene un 50% del contenido original en granito rojo después de 5-6 km. de transporte

The longitudinal association between resting heart rate and psychopathic traits from a normative personality perspective

A large body of research has accumulated investigating the possibility of an association between resting heart rate and psychopathic traits, with meta-analysis suggesting a modest, negative association. Some recent research suggests that prior findings of an association between heart rate and psychopathy may be influenced by inclusion of antisocial behavior in the assessment of psychopathic traits. The current study explores this possibility in a longitudinal sample of British males by comparing resting heart rate at age 18 to psychopathy assessed from a Five Factor Model perspective and from the Psychopathy Checklist: Screening Version (PCL:SV) at age 48. Our psychopathic personality scale, created using the Big Five Inventory (BFI), was significantly correlated with the PCL:SV and was most related to the antisocial factor. In correlation analyses, resting heart rate at age 18 was not significantly related to BFI psychopathy, but was positively related to BFI Openness and Conscientiousness, and these associations held up after controlling for childhood SES, BMI at 18, and whether the participant smoked during the age 18 assessment. Additional analyses controlling for smoking status were conducted to address the biasing effect of smoking on heart rate during the age 18 assessment and a significant, albeit weak, negative association between resting heart rate and BFI psychopathy emerged. Future research should replicate these results using other normative personality approaches to assess psychopathic traits.We are very grateful to the Home Office, the Department of Health, the Department of Education, the Rayne Foundation, the Barrow Cadbury Trust, and the Smith-Richardson Foundation for funding the Cambridge Study in Delinquent Development

Examining the association between childhood cognitive ability and psychopathic traits at age 48

Despite early theorists suggesting that psychopathic traits are associated with higher intelligence, meta-analytic work has found that global psychopathy scores are actually negatively related to intelligence, albeit weakly. Furthermore, it was reported in the same meta-analytic work that the various dimensions of psychopathy were differentially related to intelligence. Importantly, virtually all of the research to date has relied on cross-sectional associations. The current study examined whether intelligence scores (verbal comprehension, non-verbal IQ, and a global intelligence composite) at age 8 were associated with psychopathy scores at age 48 in a sample of white, urban males from London (analytical n = 292). Results suggested a significant, but weak, inverse association between intelligence and the affective, lifestyle, and antisocial facets of psychopathy and a nonsignificant association with the interpersonal facet, as assessed by the Psychopathy Checklist: Screening Version. These findings contribute to the growing body of evidence suggesting that psychopathy, as conceptualized in most modern models, is either very weakly inversely related to, or simply not a correlate of intelligence.We are very grateful to the Home Office, the Department of Health, the Department of Education, the Rayne Foundation, the Barrow Cadbury Trust, and the Smith Richardson Foundation for funding the Cambridge Study in Delinquent Developmen

Behind the confession: Relating false confession, interrogative compliance, personality traits, and psychopathy

The present study further supports the established notion that personality traits contribute to the phenomenon of false confessions and compliance in an interrogative setting. Furthermore, the study provides an investigation into the more recent interest in the potential effect of psychopathic traits in this context. A sample of university students (N = 607) completed questionnaires measuring psychopathic traits, interrogative compliance, and the big five personality factors. Of these, only 4.9% (n=30) claimed to have falsely confessed to an academic or criminal offense, with no participant taking the blame for both types of offense. Across measures the big five personality traits were the strongest predictors of compliance. The five personality traits accounted for 17.9 % of the total variance in compliance, with neuroticism being the strongest predictor, followed by openness and agreeableness. Psychopathy accounted for 3.3% of variance, with the lifestyle facet being the only significant predictor. After controlling for the big five personality factors, psychopathy only accounted for a small percentage of interrogative compliance, indicating that interrogators should take into account a person’s personality traits during the interrogation.N/
