Since the door on the dryer is made of heat resistant glass, I can see the drum rotate. NLM NIH DHHS USA.gov National Center for Biotechnology Information, U.S. While both Aaro-Dahlborn and Ho et al's methods proved clinically applicable and accurate, the study also showed that interobserver reliability was significantly better in the latter technique.One concern related to axial Bulletin of the Psychonomic Society. 29 (2): 209–212.

Each stimulus was a two-dimensional image of a three-dimensional object drawn by a computer. Overall, many studies reported that the Perdriolle torsion meter is suitable for use in the clinic. I have gotten multiple answers such as 1.033 and 1.039 and 1.077. (all wrong) Please help!
Following the basic ideas of Shepard and Metzler's experiment, this study found a significant difference in the mental rotation scores between men and women, with men performing better. Thoracic idiopathic scoliosis curve evaluation and prognosis. pp. 297–301.Al-Adra D, Arnett J, Rajwani T, Bagnall K. In comparison to the spinous process, the pedicles are located closer to the vertebral body and, consequently, are not subject to as much distortion in severe scoliotic cases [23,25].Despite these improvements,
Such factors include intravertebral rotation, inclination in different planes, and large rotation angles – the prominence and effect of each being dependent on the particular method used. In a separate study, both Aaro-Dahlborn and Ho's methods showed similar accuracy. Spine. 2006;31:E80–E83. Published online 2008 Nov 2.

Errors due to poor clarity of vertebral structures, an obstacle for many radiographic techniques, are reduced. Poor rotators will be more likely to represent color in their mental rotation using piecemeal strategies (Khooshabeh & Hegarty, 2008).

Then, a second line runs through the midline of the vertebral body is drawn. Measurement of vertebral rotation in standing versus supine position in adolescent idiopathic scoliosis.
Measurement error in assessment of vertebral rotation using the perdriolle torsionmeter. Spine. 1991;16:599–600. While radiography yields images with poorer clarity and involves exposure of a larger bodily region to radiation, it entails less radiation exposure overall. When a vertebra rotates, the rotation angle θ by Stokes method is θ=tan−1(12×a−ba+b×wh); where a and b are the center of the pedicles relative to the center of the vertebra, respectively;
One of the theories concerning autism is the EMB (extreme male brain). There is a relationship between similar areas of the brain associated with perception and mental rotation. The aim of these new developments is to reduce the number of false positives referred to scoliosis clinics through school screening programs as well as unnecessary exposure to radiation. Traditionally, measurement of Cobb angles was the primary means of quantifying the severity of AIS in scoliotic patients.
Mental Images in Human Cognition. 80. This encourages us to think about the role of our social position on our capacities. However, there presently exist limited studies evaluating Stokes' method, rendering it difficult to reach fair judgments. Seven volunteers (four males and three females) between the ages of twenty-nine to sixty-six participated in this experiment.
