SummaryIn relation to two measures of the mobility involved in the migration histories of individuals now resident in the Otmoor villages of Oxfordshire, selectivity for components of the Wechsler Adult Intelligence Scale is clearly demonstrated. However, this selectivity is reconsidered in the light of other covariates of mobility, where these also relate to IQ, for example, some measures of temporal and socioeconomic variation. When correction is made for these, the frequency of highly significant correlations is greatly reduced, suggesting that much of the selectivity operates within the associations between mobility, IQ, and the confounding temporal and socioeconomic variables. There remains, even after removal of the effects of age, class and occupation-type, a pattern of significant association between some components of verbal IQ and the measures of mobility.

This study investigates Verbal, Performance, and Full Scale IQ change in an institutionalized mentally retarded population. 402 individuals who had received two routine administrations of either the Wechsler Intelligence Scale for Children or the Wechsler Adult Intelligence Scale and who ranged in age from 11 to 44 were included as subjects. They were divided into six groups (two WISC and four WAIS) and changes in scores were studied using a semi-longitudinal methodology. Contrary to the dominant view suggested by previous research, Full Scale IQ did not decrease with age. There were, in fact, slight increments, larger and more consistent in Performance than Verbal IQ. This differential change is discussed in terms of the Horn-Cattell theory of “fluid” and “crystallized” intelligence.

Aims: Adolescence is a critical period because the brain is involved in the process of maturation that entails cognitive functions. On the way of maturation, an individual’s inhibitory control undergoes many changes and becomes vulnerable to different thrill-seeking like smoking, drinking, and so on. Smoking is highly prevalent among teenagers that are trying to take control of their behaviors in order to join society. They experience antisocial behavior too which is a trait that can lead adolescents to addiction. This trait is an inevitable part of psychopathy. Inhibitory deficits and psychopathy have been widely reported in addiction studies. The current study tried to investigate the relationship between psychopathic traits and behavioral inhibition between male smokers and non-smoker teenage students.Materials & Methods: Statistical sample of this research is 62 teenage students aged 17 years that are divided into smoker and non-smoker groups. The participants have been chosen through random sampling from the population of 10 high schools. The data have been gathered in Kordkoy and Gorgan in Golestan province. Behavioral bias has been measured by Go/NoGo task and psychopathic traits through youth psychopathic traits inventory. Also, the short form of Wechsler Adult Intelligence Scale test has been executed and used as a control variable.Findings: A meaningful difference has been found between the performance of smoker and non-smoker groups in Go/No Go task and psychopathic traits that are smokers performed weaker in comparison with non-smokers and psychopathic traits of smokers were meaningfully higher than non-smokers. On the other hand, there was no significant difference between these two groups in their Wechsler Adult Intelligence Scale scores.Conclusion: The results have shown that smokers have higher psychopathic traits and lower behavioral inhibition when compared with their non-smoker peers. According to the results of current research, smoking can decline the cognitive functions.
