Summery— Cain and Vanderwolf (Personality and Individual Differences 11, pp. 777-784, i990) commit a G rand Type II E rror in denying the relation between the variables juxtaposed in the title o f this rejoinder. This reply (a) presents 20 studies showing a positive correlation between brain size and IQ, one of which used magnetic resonance imaging to scan the brain, (b) re-examines whether the...

Mat erial and Methods: because of its anatomical and functional relationship with the craniofacial complex, we assessed the cephalometry of the hyoid bone position in relation to the respiratory pattern of these 53 female children, with average age of 10 years; 28 of them are nasal breathers and 25 are oral breathers. Horizontal, vertical and angular cephalometric measures were used in order to...

Measurements of the human face as part of the body have been performed since the Greek era, and many aspects of ancient measurements can be found in modern clinical anthropometry. A historical appraisal of the use of facial measurements is presented. The influence on modern facial anthropometry of Greek proportion sciences, the golden proportion, canons of important Renaissance artists, physica...

OBJECTIVE To observe the impact on maxillary growth of the use of buccal fat pads to pack palate relaxing incisions. METHODS We recruited 30 patients aged 3-4 years with a complete cleft palate. Half (15) of the patients underwent reparative surgery that entailed packing buccal fat pads into the bilateral raw bony surfaces and served as the experimental group. The remaining 15 patients underw...

Three measurements of head at unique locations form a three-point estimator of the local magnitude and orientation of the hydraulic gradient. The relative head measurement error (RHME) is defined here as the measurement error normalized by the head drop across the three-point estimator. Monte Carlo simulation results show that estimators with base to height ratios between 0.5 and 5.0 and that a...

In the present study, regression equations between body and head length measurements for the broad-snouted caiman (Caiman latirostris) are presented. Age and sex are discussed as sources of variation for allometric models. Four body-length, fourteen head-length, and ten ratio variables were taken from wild and captive animals. With the exception of body mass, log-transformation did not improve ...
