The asymmetrical tonic neck reflex (ATNR) is a primitive reflex found in newborn humans that normally vanishes around 6 months of age. It is also known as the bow and arrow or "fencing reflex" because of the characteristic position of the infant's arms and head, which resembles that of a fencer. When the face is turned to one side, the arm and ...
Knee jerk or patellar reflex — a kick caused by striking the patellar tendon with a tendon hammer just below the patella, stimulating the L4 and L3 reflex arcs. Moro reflex , a primitive reflex — only in all infants up to 4 or 5 months of age: a sudden symmetric spreading of the arms, then unspreading and crying, caused by an unexpected ...
A dog communicates by altering the position of its head. When the head is held in an erect position this could indicate that is approachable, attentive, curious, or aggressive. Turning the head away may indicate fear, but is also recognized as a calming signal. [13] A dominant dog will display an upright posture and/or stiff legs. [13]
The results of the study showed that the sucking reflex was performed normally most often (63.5%), followed by the Babinski reflex (58.7%), and the Moro reflex (42.9%). The study concluded that high-risk newborns presented more periodic abnormal and absent responses of primitive reflexes, and that each reflex varied in response.
The symmetrical tonic neck reflex (STNR) is a primitive reflex that normally emerges during the first month of an infant's life and is diminished by the age of 9–10 months. [1] It is a bridging or transitional brainstem reflex that is an important developmental stage and is necessary for a baby to transition from lying on the floor to ...
There are two frequently used placing reflexes. They are tests which allow clinicians to assess the proprioceptive abilities of small domestic animals (cats and dogs in particular). The first test is to lift an animal and bring the anterior/dorsal surface of a paw up to a table edge. The normal animal will position its paw onto the surface ...
In the first few trials, the dog did not move until the shocks began and then it jumped over the barrier. However, after several trials, the dog began to make avoidance responses and would jump over the barrier when the light turned off, and would not receive the shock. Many dogs never received the shock after the first trial.
The Intelligence of Dogs: A Guide to the Thoughts, Emotions, and Inner Lives of Our Canine Companions is a 1994 book on dog intelligence by Stanley Coren, a professor of canine psychology at the University of British Columbia.
