Single-handedness

Recent experiments and observations, however, prove that single-handedness is merely the result of faulty or restricted education. Careful observations have shown that out of every hundred persons born into this world eighty are congenitally ambidextrous — that is to say, they will instinctively reach for an object with either hand

But as we rise in the evolutionary scale of normal creatures, and as we exclude disease, ambidexterity progressively gives way to single-handedness, generally right-handedness.

One step in my method of correcting the stutterer is to build up a single-handedness or sidedness in the individual.

In the complexes, the direction and affinity of the hydroxy group for hydrogen bond toward the carboxy group of poly-12 may be the most important factor to control both the helical sense and an extent of the single-handedness, and therefore, the complexes with amino alcohols showed an intense ICD independent of the bulkiness of the substituent (R) with the same Cotton effect signs as the primary amines.
