The Concept of the Reflex in the Description of Behavior 321
THE CONCEPT OF THE REFLEX IN THE DESCRIPTION OF BEHAVIOR 321 The present paper was published in the Journal of General Psychology, I I 2 * s here the editor. ( 93 > 5' 4 7~45$) an^ reprinted by permission of INTRODUCTORY NOTE THE EXTENSION of the concept of the reflex to the description of the behavior of intact organisms is a common practice in modern theorizing. Nevertheless, we owe most of our knowledge of the reflex to investigators who have dealt only with "preparations," and who have never held themselves to be con- cerned with anything but a subsidiary function of the central nervous system. Doubtless, there is ample justification for the use of relatively simple systems in an early investigation. But it is true, nevertheless, that the concept of the reflex has not emerged unmarked by such a circumstance of its development. In its extension to the behavior of intact organisms, that is to say, the his- torical definition finds itself encumbered with what now appear to be super- fluous interpretations. The present paper examines the concept of the reflex and attempts to evaluate the historical definition. It undertakes eventually to frame an alterna- tive definition, which is not wholly in despite of the historical usage. The reader will recognize a method of criticism first formulated with respect to scientific Ernst Mach in The Science and concepts by [ of Mechanics} per- haps better stated by Henri Poincare. To the works of these men and to Bridgman's excellent application of the method [in The Logic of Modern Physics] the reader is referred for any discussion of the method qua method. -
Retained Neonatal Reflexes | the Chiropractic Office of Dr
Retained Neonatal Reflexes | The Chiropractic Office of Dr. Bob Apol 12/24/16, 1:56 PM Temper tantrums Hypersensitive to touch, sound, change in visual field Moro Reflex The Moro Reflex is present at 9-12 weeks after conception and is normally fully developed at birth. It is the baby’s “danger signal”. The baby is ill-equipped to determine whether a signal is threatening or not, and will undergo instantaneous arousal. This may be due to sudden unexpected occurrences such as change in head position, noise, sudden movement or change of light or even pain or temperature change. This activates the stress response system of “fight or flight”. If the Moro Reflex is present after 6 months of age, the following signs may be present: Reaction to foods Poor regulation of blood sugar Fatigues easily, if adrenalin stores have been depleted Anxiety Mood swings, tense muscles and tone, inability to accept criticism Hyperactivity Low self-esteem and insecurity Juvenile Suck Reflex This is active together with the “Rooting Reflex” which allows the baby to feed and suck. If this reflex is not sufficiently integrated, the baby will continue to thrust their tongue forward, pushing on the upper jaw and causing an overbite. This by nature affects the jaw and bite position. This may affect: Chewing Difficulties with solid foods Dribbling Rooting Reflex Light touch around the mouth and cheek causes the baby’s head to turn to the stimulation, the mouth to open and tongue extended in preparation for feeding. It is present from birth usually to 4 months. -

The Corneomandibular Reflex1

GORDON2 AND MORRIS B. BENDER From the Department of Neurology, the Mount Sinai Hospital, New York, U.S.A. SUMMARY Seven patients are presented in whom a prominent corneomandibular reflex was observed. These patients all had severe cerebral and/or brain-stem disease with altered states of consciousness. Two additional patients with less prominent and inconstant corneomandibular reflexes were seen; one had bulbar amyotrophic lateral sclerosis and one had no evidence of brain disease. The corneomandibular reflex, when found to be prominent, reflects an exaggeration of the normal. Therefore one may consider the corneomandibular hyper-reflexia as possibly due to disease of the corticobulbar system. The corneomandibular reflex consists of an involun- weak bilateral response on a few occasions. This tary contralateral deviation and protrusion of the was a woman with bulbar and spinal amyotrophic lower jaw during corneal stimulation. It is not a lateral sclerosis.

Auenbrugger, Laennec, and John Keats
AUENBRUGGER, LAENNEC, AND JOHN KEATS SOME NOTES ON THE EARLY HISTORY OF PERCUSSION AND AUSCUTLATION* by SAUL JARCHO FRIAR I IGO ABBAD, the eighteenth-century historian of Puerto Rico, refers in sarcastic terms to Ponce de Le6n, who went to Florida to look for the Fountain of Youth and who came back older than he was when he set out.' Although travel to Florida has unquestionable merit, there is an alternative method-of rejuvenation which I wish to recommend. It consists of seeking one's youth by seeking out the company of the young. By such ratiocination we conclude that an evening spent with the Osler Society in the month of February is preferable to a fortnight on the sands of Miami. All those who have been through the mill of medical schooling and almost all ofthose who are in the process of being milled will remember the difficulties they experienced while learning physical diagnosis. Accordingly it has seemed appropriate to select for presentation this evening a discussion of the history of that art. Since I am your guest and not your anesthetist I shall limit my re- marks to a short part of the long narrative. The Traditional Account Let us begin by recalling the traditional story. It is often said that Leopold von Auenbrugger (I722-1809), an innkeeper's son, observed barrels of wine or beer being sounded in his father's cellars. The bright boy later studied medicine and treated his patients like beer barrels. This led to his great dis- covery of thoracic percussion, which he announced with the statement that thorax.. -

THE BABINSKI REFLEX.1 by C
THE BABINSKI REFLEX.1 By C. Van Epps, M.D. I owe the opportunity to make the following study to my chiefs at the Philadelphia Hospital, Drs. Mills, Dercum, Lloyd and Burr, and to the chief resident physician, Dr. Daniel E. Hughes. The purpose of my investigation was to determine the conditions in which the Babinski reflex is present. The data consisted of one thousand persons classi¬ fied as follows:— Babies and children. ioo Patients in medical wards presenting no ner¬ vous symptoms. 165 Insane patients presenting no organic cerebro¬ spinal disease. 335 Patients suffering from nervous disease but pre¬ senting no symptoms of involvement of the lateral tracts . 213 Hemiplegics and diplegics . 125 Patients having disease of the spinal cord with manifest involvement of the lateral tracts. 62 In health on stroking the sole there follows flexion of the toes with or without movement of the ankle and leg. This reflex is not present in every one, some normal persons hav¬ ing no plantar reflex at all. Babinski discovered that in certain diseases the plantar reflex is altered and claimed that this alteration is constantly present whenever there is “perturbation” of the lateral tracts. He described the alteration as follows: There is extension of the great toe with or without extension and separation of the other toes, the movement being slower than the normal reflex and more readily produced by stroking the outer than the inner side of the sole. In testing for the reflex I used, as a rule, an ordinary blunt tooth-pick; if the sole was very sensitive I used my ‘Read before the Philadelphia Neurological Society, October 22, 1900. -
