F. Matthias Alexander developed an ability that avoided what negative bodily issue?
Alexander Technique The Alexander Technique (A.T.), named after Frederick Matthias Alexander, is an educational process that attempts to develop the ability to avoid unnecessary muscular tension by retraining physical movement reactions. Alexander believed the individual's spatial self-awareness was related to psychological conditioning; questionably trained foundation habits of posture can be unsuitably added into procedural skills. Alexander observed that those whose goals justified it necessary to have trained themselves to overcompensate could not trust their judgment of physical orientation and required effort, (their "sensory appreciation.").
Lee–Boot effect The Lee–Boot effect is a phenomenon concerning the suppression or prolongation of oestrous cycles of mature female mice (and other rodents), when females are housed in groups and isolated from males. It is caused by the effects of an oestrogen-dependent pheromone, released via the urine, that acts on the vomeronasal organ of recipients. This pheromone lowers the concentration of luteinizing hormone and elevates prolactin levels, synchronising or stopping the recipient’s cycle. This effect goes some way to explain why spontaneous pseudopregnancy can occur in mice. The same response is invoked from isolated females when brought into contact with urine-soaked bedding from other females’ cages. Removing the vomeronasal organ of recipients causes an ineffective response – indicating that the cues are not mediated by the vomeronasal system.
