Which description best fits the Parachute Reflex?
Legs extend when child is rapidly lowered toward the ground
What is a key difference between primitive reflexes and postural reflexes?
Postural reflexes are incorporated into general movements
What is the main function of locomotor reflexes?
Facilitate voluntary gait
What was the traditional belief regarding voluntary movement and reflexes?
Reflexes must be completely inhibited for voluntary movement to occur
What is the main purpose of infantile reflexes according to the text?
To facilitate survival and interaction with the environment
What is the significance of the Moro reflex in infants?
Signifies possible injuries to one side of the brain
What type of reflex is the Palmar Grasping reflex?
Primitive reflex
Why do infantile reflexes occur according to the text?
To stimulate sensory consequences and facilitate development
What characterizes postural reflexes according to the text?
They maintain posture in a changing environment
What do infantile reflexes involve according to the text?
Single muscles or specific muscle groups
How do primitive reflexes differ from postural reflexes according to the text?
'Primitive' are involuntary stereotyped responses while 'postural' are voluntary.
What is the purpose of the Doll-eye reflex in infants?
Stimulates vestibular development
Which type of infantile reflex is characterized by a fanning out of toes in response to a stimulus on the sole of the foot?
Babinski Reflex
What is a common consequence of persistent Moro reflex according to the text?
Delayed sitting and head control
What does the Palmar Grasping Reflex involve closing tightly around according to the text?
An object or finger touched in palm
Which part of an infant's body does the Symmetric tonic neck reflex involve according to the text?
Arms and neck
What does the maturational perspective on development suggest about the role of the CNS in guiding early motor behavior?
The CNS is the only factor influencing early motor behavior.
What term is used to describe movements like supine kicking that occur without any apparent stimulation?
Spontaneous movements
According to recent evidence, how does brain development interact with movement?
Movement also affects brain development.
What type of movements do Thelen and colleagues specifically focus on in their study?
Spontaneous movements
How do spontaneous (stereotypic) movements like supine kicking differ from reflexive movements?
Reflexive movements only occur in response to stimuli, but spontaneous movements do not.
Why is it significant that certain infant movements occur in the absence of any stimuli?
It challenges earlier assumptions and highlights interactions between movement and brain development.
What is the purpose of the Derotative Righting Reflex according to the text?
To aid in the development of equilibrium reactions
Which category describes the role of reflexes as a byproduct of the developing neurological system?
Structural roles
What is the main difference between Locomotor reflexes and voluntary movement according to early researchers?
Reflexes inhibit voluntary movement
What is the primary function of the Parachute Reflex in infants?
To extend legs when tilted backwards
How do postural reflexes differ from primitive reflexes according to the text?
Postural reflexes are incorporated into general movements, unlike primitive reflexes
What type of response is elicited by the Swimming Reflex in infants according to the text?
Facilitation of equilibrium in motion
What is the current theory regarding movements in infants?
Movements are building blocks for voluntary movements.
Why do infantile reflexes occur according to the text?
To promote survival and facilitate interaction with the environment.
What role do postural reflexes play according to the text?
Facilitate posture maintenance in a changing environment.
What is the main function of the Symmetric Tonic Neck Reflex?
Help with vestibular development.
How do primitive reflexes differ from postural reflexes as per the text?
Primitive reflexes involve the whole body, while postural reflexes involve specific muscle groups.
What is the consequence of persistent Moro reflex according to the text?
Delayed sitting and head control.
Which type of movement is characterized by sudden extension of arms and legs after gently lowering the baby's head?
Moro Reflex
What happens during the Palmar Grasping reflex?
The hand closes tightly around an object
What is the primary stimulus for the Sucking Reflex?
Touching the face above or below the lips
What is a key difference between primitive and postural reflexes according to the text?
Primitive reflexes are involuntary and stereotyped, while postural reflexes are voluntary and adaptive.
What is a common consequence of Doll-eye Reflex?
Eyes open and close repeatedly
Explore the relationship between cognitive development and movement in infants. Learn about the maturational perspective on development, from primitive reflexes controlled by the brainstem/spinal cord to equilibrium reactions governed by the cerebral cortex. Discover how recent evidence challenges the idea of unidirectional control of early motor behavior.
