Compared with individuals with low gambling-related cognitive bias, those with high levels of such bias showed greater degrees of trait impulsivity.
Thus, further investigation of activity in this region in healthy participants with various degrees of trait anxiety may prove useful in identifying markers indexing individual variations in the susceptibility to affective disorders, in general, and to anxiety-related psychiatric conditions, in particular.
The rationale that makes Rasch models useful as a method to shorten the size of a questionnaire is that they can be employed to assess the unidimensionality of questionnaires, and remove items that disrupt this unidimensionality, identify degrees of trait severity and remove those items that overlap in severity level [ 18].
This study demonstrated that the degree to which autistic traits and traits of ADHD share genetic and environmental influences with one another varies by autistic trait domain, showing for the first time that this pattern is also apparent amongst individuals in the general population displaying particularly extreme degrees of traits of ASC and ADHD.
Within the subtrait of physical aggression, however, the degree of trait manifestation proved inconsequential for impulsive aggression, but exposure to the violent film segment resulted in more frequent use of impulsive aggressive responses than exposure to the innocuous film segment.
In order to compare phylogenetic signal among traits and phylogenies, Blomberg et al. [22] developed a K statistic, which is a descriptive statistic that indicates the degree of trait similarity among closely related species relative to expectations from a Brownian motion model of trait evolution.
Similarly, plant mating system also affected the degree of trait correspondence because selfing reduces the reliance on pollinators and is analogous to pollination generalization.
Interestingly, results have been presented [ 22] showing that individual differences seem to exist between individuals with a high degree of trait anxiety and high attentional control and individuals with a high degree of trait anxiety and low attentional control regarding attentional disengagement from threatening stimuli.
Both Moran's and Mantel tests are general procedures for testing for spatial or genetic autocorrelation [ 39], whereas Blomberg's K is a descriptive statistic based on a Brownian (random walk) model of trait evolution (BM), with a value of 1 corresponding to the degree of trait similarity expected under BM.
Across communities, the degree of trait mismatch between one specialist plant and its more generalized pollinator was related to the level of pollinator specialization at each site; the observed pattern supports the "life-dinner principle" of selection acting more strongly on species with more at stake in the interaction.
According to Spielberger and colleagues [14], individuals with a higher degree of trait-like cognitive anger are more likely to have more frequent state-like experiences of affective anger.
