Neurocranium versus Face: A Morphometric Approach with Classical Anthropometric Variables for Characterizing Patterns of Cranial Integration in Extant Hominoids and Extinct Hominins

The relative importance of the two main cranial complexes, the neurocranium and the splanchnocranium, has been examined in the five species of extant hominoids and in a huge sample of extinct hominins using six standard craniometric variables that measure the length, width and height of each cranial module. Factor analysis and two-block partial least squares were used for establishing the major patterns of developmental and evolutionary integration between both cranial modules. The results obtained show that all extant hominoids (including the anatomically modern humans) share a conserved pattern of developmental integration, a result that agrees with previous studies. The pattern of evolutionary integration between both cranial modules in australopiths runs in parallel to developmental integration. In contrast, the pattern of evolutionary and developmental integration of the species of the genus Homo is the opposite, which is probably the consequence of distinctive selective regimes for both hominin groups.JAPC, JMJA and PP received fundings from Ministerio de Ciencia e Innovación, Gobierno de España (http://www.idi.mineco.gob.es), project CGL2011-30334, and Consejería de Economía, Innovación, Ciencia y Empleo, Junta de Andalucía, España (http://www.juntadeandalucia.es/organismo​s/economiainnovacioncienciayempleo.html), project P11-HUM-7248 and Research Groups RNM-146 and HUM-607

The scale properties of the adolescent form of the Francis Psychological Type Scales (FPTSA) among Canadian Baptist youth

A sample of 755 religiously committed young people between the ages of 12 and 18 attending Tidal Impact (a weeklong youth mission and service event sponsored by the Convention of Atlantic Baptist Churches in Eastern Canada) completed a trial 80-item form of the Francis Psychological Type Scales designed for use among adolescents. These data were employed to refine four ten-item forced-choice scales to distinguish between preferences for the two orientations (extraversion and introversion), the two perceiving processes (sensing and intuition), the two judging processes (thinking and feeling) and the two attitudes (judging and perceiving). The scale properties of the new instrument commend the 40-item Adolescent form of the Francis Psychological Type Scales (FPTSA) for future use
