The authors said a trial involving more than 500 families trained to use non-physical punishments found that problem behaviour declined.
Oscillatory behaviour declined with increasing repetition of trials, suggesting a learning effect [ 25].
If this interpretation of head-dipping is correct, we would also predict that, as head-dipping behaviour declines, fearfulness would also decline.
With the 2010 procedure, we found a rise in the variance attributable to candidate (18%) and candidate*station (33%), while differences in rater behaviour declined (45%).
When age was modelled as a continuous variable, the odds ratio for suicidal behaviour or ideation declined at a rate of 2.6% per year of age (−3.9% to −1.3%, P=0.0001) and the odds ratio for suicidal behaviour declined at a rate of 4.6% per year of age (−7.4% to −1.8%, P=0.001).
We predicted that feeding behaviour would decline under ML evolution if there were a trade-off between feeding and other activities such as courtship, territoriality or locomotor activity associated with male fitness.
Results from the regression models showed that, after adjustment for changes in age, nationality, education and changes in sexual risk behaviour, the decline in HSV-2 prevalence among HIV negative MSM remained significant (PRR adjusted 0.92, P < 0.001).
This pronounced shift in foraging behaviour to declining use of deer during fall was strongly related to salmon use; using 'group years' as cases, there was a strong inverse relationship between O/I of salmon and O/I of deer during fall (r = -0.77, n = 20, P < 0.001, Figure 3).
Two important aspects of energy expenditure that contribute to excessive weight gain in adolescents are sedentary behaviour and declining levels of physical activity, both being behavioural and therefore modifiable [ 38].
Others in the arts world agree that audience behaviour has declined, but say that young people are not the worst – or only – offenders.
