Physical punishment is associated with a range of mental health problems in children, youth and adults, including depression, unhappiness, anxiety, feelings of hopelessness, use of drugs and alcohol, and general psychological maladjustment.26 — 29 These relationships may be mediated by disruptions in parent — child attachment resulting from pain inflicted by a caregiver, 30,31 by increased levels of cortisol32 or by chemical disruption of the brain's mechanism for regulating stress.33 Researchers are also
finding that physical punishment is linked to slower cognitive development and adversely affects academic achievement.34 These
findings come from large longitudinal
studies that control for a wide range of potential confounders.35 Intriguing results are now emerging from
neuroimaging studies, which suggest that physical punishment may reduce the volume of the brain's grey matter in areas associated with performance on the Wechsler Adult Intelligence Scale, third edition (WAIS - III).36 In addition, physical punishment can cause alterations in the dopaminergic regions associated with vulnerability to the abuse of drugs and alcohol.37
The strongest research methods for psychological
studies are: qualitative
findings versus quantitative; experimental rather than descriptive or correlational; controlled - experiment, meta - analysis, and observation designs over archival, case
study, computational modeling, content analysis, field experiment, interview,
neuroimaging, quasi experiment, self - report inventory, random sample survey, or twin
study; and prospective (where subjects are recruited prior to the proposed independent effects being administered) and longitudinal (where subjects are
studied at multiple time points) rather than retrospective or cross-section
study.
Consequently, the magnitude of per - visit
neuroimaging use
found in this
study suggests considerable overuse,» the authors write.
It's «a solid piece of evidence showing that those of us in
neuroimaging need to do a better job thinking about our sample, where it's coming from and who we can generalize our
findings to,» says Christopher Monk, who
studies psychology and neuroscience at the University of Michigan in Ann Arbor.
In late 2012 he finally
founded Neural Bytes, which models human brain processing using data from neurophysiological and
neuroimaging studies.
Schulze added, «It is my hope that these
findings will give an impetus to future
neuroimaging studies evaluating different treatment options in BPD, such as psycho - or pharmacotherapy.»
The use of
neuroimaging was part of an effort to
find noninvasive ways of
studying pig brain development that could also be applied in humans.
In 2009 Dr. Drevets became the first President and Scientific Director of the Laureate Institute for Brain Research in Tulsa, OK, a private research institute
founded and supported by The William K. Warren Foundation, to lead a multidisciplinary team in
studies aimed at investigating interrelationships between
neuroimaging, genetic and other biomarkers, illness course, and treatment outcome in psychiatric disorders.
Adopting one of these approaches to pubertal assessment when
studying adolescents will likely contribute to clarity and interpretability of
neuroimaging findings in this population.
There are a few longitudinal
findings from structural
neuroimaging studies spanning the developmental period discussed in this review.
In an intriguing
neuroimaging study of musical improvisation in classically trained pianists, Bengtsson et al. [13]
found activations in the right dorsolateral prefrontal cortex, as well as premotor and auditory areas during improvisation.
The emotional part of the brain, the amygdala, is much more active when deprived of sleep,
finds a
study by Matthew P. Walker, PhD, director of the Sleep and
Neuroimaging Laboratory at the University of California, Berkeley.
Given that the brain has potential for plasticity, many researchers question whether sex differences
found in
neuroimaging studies are because of biologically set, universal sex differences, or due to the influence of environmental or cultural factors on brain development (Fine, 2013).
Analogous to similar
neuroimaging studies of individual differences in human social reward, our
findings demonstrate a neural mechanism for preference in domestic dogs that is stable within, but variable between, individuals.
These
findings extend the substantial body of behavioral data demonstrating the deleterious effects of poverty on child developmental outcomes into the neurodevelopmental domain and are consistent with prior results.8, 9 Furthermore, these
study findings extend the available structural
neuroimaging data in children exposed to poverty by informing the mechanism of the effects of poverty on hippocampal volumes.
Given their typical age of onset, a broad range of mental disorders are increasingly being understood as the result of aberrations of developmental processes that normally occur in the adolescent brain.4 — 6 Executive functioning, and its neurobiological substrate, the prefrontal cortex, matures during adolescence.5 The relatively late maturation of executive functioning is adaptive in most cases, underpinning characteristic adolescent behaviours such as social interaction, risk taking and sensation seeking which promote successful adult development and independence.6 However, in some cases it appears that the delayed maturation of prefrontal regulatory regions leads to the development of mental illness, with neurobiological
studies indicating a broad deficit in executive functioning which precedes and underpins a range of psychopathology.7 A recent meta - analysis of
neuroimaging studies focusing on a range of psychotic and non-psychotic mental illnesses
found that grey matter loss in the dorsal anterior cingulate, and left and right insula, was common across diagnoses.8 In a healthy sample, this
study also demonstrated that lower grey matter in these regions was
found to be associated with deficits in executive functioning performance.
Our results are in line with other
neuroimaging studies that have
found reduced activations to different kinds of affective stimuli within the brain emotional systems in violent adult subjects and in adolescents with conduct disorder.
