Despite early success, the treatment was not developed until the 1930s by two independent groups of psychologists: Orval Mowrer and Willie Mae Mowrer (1938) and John Morgan and Frances Witmer (1939). [1] Mowrer used a modified Pfaundler alarm device with 30 children (ages 3–13 years) showing empirical success of the bell and pad method as a ...

Getting a good night's sleep can be a little more challenging amid the hype of the holidays. With changes in routine, diet and potentially time zones, quality sleep could be difficult to come by ...
In the two process model of sleep, it has been proposed, that depression is characterized by a deficiency in the building up of process S.
