INTRODUCTION The aim of this study was to assess the relationship of chronological age with cervical vertebrae skeletal maturation, frontal sinus width and antegonial notch depth and a correlation, if any, among the three variables. MATERIALS AND METHODS The samples were derived from lateral cephalometric radiographs of 80 subjects (40 males, 40 females; age range: 10 to 19 years). Cervical v...

OBJECTIVE The purpose of this study was to investigate whether skeletal maturation using cephalometric radiographs could be used in a Brazilian population. MATERIAL AND METHODS The study population was selected from the files of the Oral Radiological Clinic of the Dental School of Piracicaba, Brazil and consisted of 128 girls and 110 boys (7.0 to 15.9 years old) who had cephalometric and hand...

Individuals with Williams syndrome display indiscriminate approach towards strangers. Neuroimaging studies conducted so far have linked this social profile to structural and/or functional abnormalities in WS amygdala and prefrontal cortex. In this study, the neuropsychological hypotheses of amygdala and prefrontal cortex involvement in WS hypersociability was explored using three behavioral tas...

The thalamus plays a role in many different types of cognitive processes and is critical for communication between disparate cortical regions. Given its critical role in coordinating cognitive processes, it is important to understand how its function might be affected by aging. In the present study, we examined whether there are age differences in low-frequency fluctuations during rest in the t...

In previous studies of memory span, participants have attended to the stimuli while they were presented, and therefore have had the opportunity to use a variety of mnemonic strategies. In the main portion of the present study, participants (first- and fourth-grade children, and adults; 24 per age group) carried out a visual task while hearing lists of spoken digits and received a post-list digi...

One determinant of peace is the role of women in society. Some studies suggest that a young age structure, also known as a “youth bulge” can facilitate conflict. Population growth and age structure are factors amenable to change in a human rights context. We propose that policies which favor voluntary family planning and the education of women can ameliorate the global burden of disease associa...

To explore the viability of a revised and more differentiated scoring system for use with the Gerontological Apperception Test (GAT; Wolk & Wolk, 1971), 102 older adults (mean age = 68.3 years) were administered the GAT. Scoring criteria were developed to reflect a variety of constructs speaking to the interpersonal, health-related, and intrapsychic dimensions of the experience of later life. F...
