Sight comes first, because the eye is such a specialized organ. Then come hearing, touch, smell, and taste, progressively less specialized senses.
Touch. This is the very first sense to form, with development starting at around 8 weeks. The sense of touch initially begins with sensory receptor development in the face, mostly on the lips and nose.
Sensory development begins during gestation and continues throughout childhood. There are seven sensory processes: taste, smell, touch, hearing, seeing, body position sense (called proprioception), and movement sensations (called vestibular input).
Explanation: Smell and taste were most likely the first primitive senses, though far more rudimentary and (probably) not associated with conscious thoughts.
Research at the University of York has shown that the accepted hierarchy of human senses — sight, hearing, touch, taste and smell — is not universally true across all cultures. Researchers found that rather than being able to predict the importance of the senses from biology, cultural factors were most important.
Understanding the Developmental Order of a Baby’s Senses. There are five senses your baby develops; touch, taste, smell, hearing and sight.
Moro or “startle” reflex
A dramatic reflex during these first few weeks is the Moro reflex. If your baby’s head shifts position abruptly or falls backward–or if he is startled by something loud or abrupt–he will extend his arms and legs and neck and then rapidly bring his arms together. He may even cry loudly.
Summary: As a fetus grows, it’s constantly getting messages from its mother. It’s not just hearing her heartbeat and whatever music she might play to her belly; it also gets chemical signals through the placenta. A new study finds that this includes signals about the mother’s mental state.
Sensory and motor development is the gradual process by which a child gains use and coordination of the large muscles of the legs, trunk, and arms, and the smaller muscles of the hands. A baby begins to experience new awareness through sight, touch, taste, smell, and hearing.
Sensory development begins during gestation and continues throughout childhood. Infants discover their world through the senses. They process the sensory information they receive and interpret the meaning of these sensations to interact with their environment.
Students learning a second language move through five predictable stages: Preproduction, Early Production, Speech Emergence, Intermediate Fluency, and Advanced Fluency (Krashen & Terrell, 1983).
Perception is based on the interpretation of signals sent to the brain by the five senses. Each sense — touch, smell, taste, sight, hearing — affects how we react to the world and how we interpret events around us. The senses can alter a memory; if someone meets a person…
How do the senses work? Your brain collects information, like smells and sounds, through your five senses: sight, hearing, touch, taste, and smell. Each of your five senses has its own special sensor. Each sensor collects information about your surroundings and sends it to the brain.
Ask children to think about the important features that the person is missing. Prompt them to suggest that the figure needs eyes. Follow the same procedure and add ears, nose, mouth, and hands. Explain that seeing, hearing, smelling, tasting, touching, and feeling are the five senses.
Taste is a sensory function of the central nervous system, and is considered the weakest sense in the human body.
3 to 6 months
At around 5 months, your baby’s sense of taste has changed and he’s able to react more to salty tastes. It’s not a good idea to give your baby salty foods at this stage, though.
By week 8 of pregnancy, your baby has developed touch receptors in his face — mostly on his lips and nose — that connect to his growing brain. Over the next few months, touch receptors start to form all over, including his genitals, palms and the soles of his feet by week 12 and the abdomen by week 17.
Babinski reflex is one of the normal reflexes in infants. Reflexes are responses that occur when the body receives a certain stimulus. The Babinski reflex occurs after the sole of the foot has been firmly stroked. The big toe then moves upward or toward the top surface of the foot. The other toes fan out.
While it’s true your baby can cry in the womb, it doesn’t make a sound, and it’s not something to worry about. The baby’s practice cries include imitating the breathing pattern, facial expression, and mouth movements of a baby crying outside of the womb. You shouldn’t worry that your baby is in pain.
Your baby will start trying to communicate her feelings as soon as she’s born. For the first few months, she can only express how she feels by moving her body and making sounds, from coos and gurgles to inconsolable crying.
So, what is sensory play? Sensory play includes any activity that stimulates your young child’s senses: touch, smell, taste, movement, balance, sight and hearing. Sensory activities facilitate exploration and naturally encourage children to use scientific processes while they play, create, investigate and explore.
In the early stages of language development, the brain is programmed to attend to speech sounds and begin to mimic them. Early on, babies like to make sounds up on their own. Later they attempt to repeat sounds and words they’re exposed to from their environment.
Infants need to learn how to move and to use their bodies to perform various tasks, a process better known as motor development. Initially, babies’ movements are simply the uncontrolled, reflexive movements they are born with.
Stimulating the senses helps with a child’s creativity and imagination, allows children to regulate, develop social skills with peers such as cooperation and turn-taking, develops motor skills, and teaches self-expression.
