- Active play: encourage movements
- Practice skills: Offer opportunities for practicing standing and walking
28
What kind of toys can help with developing fine motor skills?
Soft books or blocks
29
What parts of the brain help with motor skill development?
- Motor cortex
- Basal ganglia and cerebellum
30
What is the motor cortex?
Crucial for planning, controlling and executing voluntary movements. Walking and jumping, or writing and buttoning a shirt
31
What are the Basal Ganglia and Cerebellum?
Helps to make movements smooth & precise, plays a key role in balance, coordination and the learning of movement patterns
32
What parts of the brain help with sensory processing and integration?
- Sensory cortices
- Thalamus
33
What are the sensory cortices?
Responsible for processing sensory inputs from the sensory organs (eyes, ears). The visual cortex, auditory cortex, and somatosensory cortex (touch) interpret sensory information, allowing the brain to integrate its awareness of the surroundings
34
What is the Thalamus?
Acts as a relay station, directing sensory and motor signals to and from the cerebral cortex. It also plays a role in controlling consciousness, sleep and alertness
35
What is Neural Plasticity?
The brain's ability to reorganise itself by forming new neural connections, allowing the brain to adapt to new experiences and learn from them
36
What are the types of Brain Plasticity?
Type 1: Structural Plasticity
Type 2: Functional Plasticity
37
What is structural plasticity?
The experiences or memories that change a brain's physical structure
38
What is functional plasticity?
When brain functions move from a damaged area to an undamaged area
39
What is synaptogenesis and pruning?
Brain experiences a rapid increase in synaptogenesis, the formation of new synaptic connections. Unused connections are pruned away to make neural networks more efficient. This process is influenced by a child's interactions with their environment
40
What is synaptogenesis?
The process of forming and strengthening connections between neurons in the brain
41
What parts regulate the hormone?
The hypothalamus and pituitary gland
42
What is the hypothalamus and pituitary gland?
they regulate the release of hormones that are essential for growth and development together
43
How does hormone affect physical development?
Growth hormone affect overall physical growth, while thyroid hormones are critical for brain development & metabolism
44
Why is the regulation of sleep cycles important?
Growth hormone is primarily secreted during sleep
45
What system manages emotional and social development?
The limbic system
46
What is the limbic system?
It regulates emotion and forms memories
47
How do emotional and social experiences influence physical development?
Indirectly by affecting behaviors such as exploration & play, which are important for developing motor skills & physical health
48
What are general signs of impaired physical development?
- Persistent toe walking: Walking on toes beyond the age of 2
- Difficulty in changing activities
- Lack of interest in age-appropriate toys: Not showing interest in toys that involve physical activity or coordination by expected age
49
What are signs of impaired physical development in infants? (birth to 12 months)
- A significant delay in reaching motor milestones, rolling over, sitting, crawling, walking
- Very stiff muscles (hypertonia) or very floppy muscles (hypotonia), which can affect their ability to move
- Reduced movement or activity, less kicking or waving, or using one side of the body more than the other
- Struggles with sucking, swallowing or chewing, which can lead to poor weight gain or growth
- Favoring one side of the body or adopting unusual postures might indicate discomfort or weaknesses
- Lack of response to visual or auditory stimuli could indicate sensory processing issues
50
What are signs of impaired physical development in toddlers? (1-3 years)
- Difficulty in walking, frequent falling, inability to climb stairs by the appropriate age
- Struggling with tasks requiring hand-eye coordination beyond the age where these skills usually develop
- Speech delays: More cognitive, however it can sometimes correlate with overall development delays
- Lack of engagement in social interactions or play
- Significant deviations from growth charts in terms of height, weight or head size might indicate nutritional, hormonal or developmental problems
51
How is sensory development important?
It plays a key role in how children understand and interact with the world around them, often overlapping and supporting the development of motor skills
52
How does vision develop for newborns to 2 months?
- Can see objects 8-12 inches away
- Limited focus (blurry)
- Primarily see high contrast colours (black, white, red)
53
How does vision develop for children aged 2 months to 4 months?
- Focus improves
- Beings to track moving objects with eyes
- Colour vision starts to develop, able to see a wider range of colours
54
How does vision develop for children aged 4 months to 6 months?
- Depth perception begins to develop
- Starts to grasp objects, coordinating vision with motor skills
55
What is depth perception?
The ability to see things in 3D and how far away they are
56
How does vision develop for children aged 6 months to 12 months?
- See more details
- Starts to recognise familiar faces and objects from a distance
- Eye-hand coordination improves, aiding in fine motor skills development
57
How does hearing develop for newborns?
- Can hear a wide range of sounds
- Can turn heads towards direction of sound
- Prefers human voices, especially caregivers
58
How does hearing develop for children aged 1 month to 3 months?
- Begins to distinguish between different sounds
- Might startle or react to loud noises
59
How does hearing develop for children aged 4 months to 6 months?
- Starts to turn their heads or eyes towards sounds
- May begin to babble, mimicking patterns of speech they hear
60
How does hearing develop for children aged 7 months to 12 months?

61
How does taste and smell develop in newborns?
- Can distinguish between sweet, sour, bitter and salty
- Shows a preference for sweet flavours - believed to be an evolutionary trait
62
How does taste and smell develop for newborns to 3 months?
Smell is also developed at birth. Newborns recognise and prefer the scent of their mother
63
How does children's sense of smell develop as they grow?
- Taste and smell continue to refine
- Exposure to various flavours and scents can influence preferences and eating habits
64
How does sense of touch develop in newborns?
- One of the most developed senses at birth
- A critical means of communication and exploration for infants
65
How does the sense of touch develop for children in their first half of a year?
- Infants bond with their caregivers through skin-to-skin contact (breastfeeding)
- Starts to explore different textures, temperatures and shapes through touch
66
How does touch develop for children aged 6 months to 12 months?
Sensitivity to touch helps in developing fine motor skills, such as grasping and manipulating objects
67
How do we support sensory development?
- Provide a variety of stimuli: Different textures, colors, sounds, experiences
- Engage in interactive play: talking, singing, reading to infants
- Safe exploration: ensuring all objects within their reach are non-toxic and not a choking hazard
68
What is proprioception and vestibular sense?
Beyond the five senses, infants also develop proprioception (sense of body position) and vestibular sense (sense of balance and movement), which are crucial for motor development and spatial orientation
69
How is a child's proprioception developed?
Develops as infants move and explore, helping them understand where their body parts are without looking
70
How is a child's vestibular sense developed?
Develops through movement, including rocking, bouncing, crawling, aiding in balance and coordination
