Psychomotor development refers to the origination of movement through conscious mental activity. There are three stages of psychomotor development: cognitive, associative, and autonomous. Children progress through average milestones of motor and cognitive development like head control, sitting, walking, and language skills between 6 months and 30 months. Factors like genetics, environment, and maternal psychological health can influence a child's development. Screening tests are used to check that development is appropriate.

Child development entails the biological, psychological and emotional changes that occur in human beings between birth and the end of adolescence, as the individual progresses from dependency to increasing autonomy. It is a continuous process with a predictable sequence, yet having a unique course for every child. It does not progress at the same rate and each stage is affected by the preceding developmental experiences. Because these developmental changes may be strongly influenced by genetic factors and events during prenatal life, genetics and prenatal development are usually included as part of the study of child development. Related terms include developmental psychology, referring to development throughout the lifespan, and pediatrics, the branch of medicine relating to the care of children.

Normal Development in Children is a very important chapter in Paediatrics subject curriculum. It is one of the diagnostic criteria for early detection of developmental deviation in children.
The three domains of human development are physical, cognitive and p.pdfannammalassociates
The three domains of human development are physical, cognitive and psychosocial.
Physical development:
Individual growth varies according to genetics, gender, culture and socioeconomic status.
Physical development starts at infancy and can last till late adolescence. It is generally divided
into eight stages being infancy; early, mid and late childhood; adolescence; early adulthood;
middle age and old age.Specific physical changes occur at each stage of physical development.
Physical development concentrates on gross and fine motor skills as well as puberty which
includes developing a control over the body, particularly muscles and physical coordination.
Gross motor skills involves moving the large muscles in the body like the arms and legs,
consciously and deliberately. It also involves balancing and stability with movements like
jumping, skipping, throwing, catching, hopping, kicking, running and galloping.
Fine motor skills involves controlling small muscles in the hands and wrists. This is achieved by
using small objects like handling scissors and writing instruments.Fine motor skills generally
follow gross motor development.
Physical growth at the infancy stage is rapid. Ther weight of the infant generally doubles over a
period of 6 months. The infant grows by 10-12 inches in length( or height) and the the
propartions change over a period of two years. The size of the head also decreases.The
subcortical areas of brain start developing first followed by cortical areas. At birth, the barin
weighs 25% of and adult brain which increases to 80% by puberty.
Physical development at childhood is rapid. By the end of second year, most children can
standup,walk/run, climb stairs, jump, and skip. From ages 4-5 they develop more speed and
agility and posture control. Fine motor skills start developing at this stage.
Physical development at adolescence starts with the beginning of puberty and ends with
adulthood. The physical age ranges from 12-18 years. At puberty distinctive physiological
changes occur, which involve increase in height, weight, sex characteristics, body composition
and internal systems. These changes are influenced by changes in hormone activity (growth
hormones, thyroid hormones and androgens).
Males develop a deeper voice during puberty and females develop breasts and increased hip size
start menstruation.
Physical development at early adulthood is observed at ages 20-40 years. At this period the
physical abilities are at their peak like muscle strength, sensory abilities, cardiac functioning etc.
One also starts aging at this period. Age related changes now varies to a great extent depending
on the biological factors like molecular and cellular changes and also choice of lifestyle. Aging
process starts during early adulthood and is characterized by changes in skin, vision and
reproductive capability. Women reach a menopause
Physical development at middle age is characterized by failing organs and body functions,
wrinled skin, lo.
A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

Psychomotor development
1. PSYCHOMOTOR DEVELOPMENT
Psychomotor refers to the origination of movement
in conscious mental activity.
It is important to understand if a child is developing
properly as it is a indicator of health, care and future
development.
Stages
Cognitive:-
Slow and choppy movements whereby the
patient has to think about the movement before
attempting it.
Associative:-
The movement require less think thinking
about it and is more fluid, however the movement is
not a permanent process.
Autonomic:-
The learner can still refine the movement
though practice but require no thinking about the
movement and it is fluid.
2. Development Definition
Development is the growth and change to a more
advance form.
Occurs due to changes in the motor cortex, more
neural encoding to be precise.
Average Milestone Dates
6 Months
By this stage they should have head control, might be
able to sit without support.
Equally they should be able to grasp a rattle and
reach for objects. They show very generalised
reactions to things (e.g. if someone leans in to them
they usually throw their hands out and laugh).
Most responses will be smiles and they should just
about be able to babble.
18 Months
They should be sitting without support, walking and
running in terms of gross motor control.
They should have a lot of fine motor control,
swapping objects between hands, pincer gripping,
turning pages of books, scribbling and stacking two
blocks.
They will be able to say one to about 15 words and
might be able to just form sentences.
They will also gain self awareness and object
permanence (idea that objects exist even if they
cannot be seen at the current point of time).
3. 30 Months
By this stage they should be able to jump and go up
and down stairs without assistance.
They should also be able to have symbolic thought
(pretending things are other things).

Denver test
Is a test to score children against average ages, like
those shown above to see if the difference should be
of any concern.
It requires four categories of tasks from the children :
social contact, fine motor skill, language, and gross
motor skill.
Growth Example
Average weight at birth = 3.6 kg
Average weight at one year = 10 kg
This shows most babies nearly triple in weight,
however premature babies can increase in weight by
ten times their birth weight.
5. Factors of Development
Development occurs from head to caudal(tail), so
initially the baby is able to see its mother, feed and
breathe.
Factors in development include:
Biological
Genetics
Intrauterine exposure
Early illnesses/prematurity
Unknown
Note:- Bonding between mother and child occurs by eye
contact, physical contact, feeding and communication.
Maternal factors of development
Psychological
Bonding and attachment
Maternal Depression
Social
Mother's education and employment
Family child rearing practices
Community Values and expectations
Environmental factors such as housing, violence etc.
Terms
Initial age – first show ability
Mean age – 50% show ability
Limit age – most show ability – need assessment

Optimal health and wellbeing aims
Motor behavior, motor performance, and motor
learning are discussed at length within the context
of infant and child development.
Individual chapters focus on the following: the
sensory-motor behavior of infants; analysis of
selected perceptual-motor programs.
7. Beginnings of movement in infants; gross motor
attributes in early childhood; visual perceptual
development; body image; manipulative behavior;
scribbling and drawing.
Motor development in children from six to twelve;
social development; the child in competitive sport;
the awkward child; and physique and ethnic
background. Attention is also addressed to the
reasons for possible individual differences in
performance and learning (race, ethnic background,
physique, etc.).
References, questions for discussion, and
suggested projects, observations, and learning
experiences are provided at the end of each
chapter, and an index is included at the end.
The book is designed primarily for use as a text in
motor and child development courses.
Factors affecting psychomotor skills
Psychological feedback
Amount of practice
Task complexity
Work distribution
Motive-incentive conditions
8. Environmental factors
Psychomotor learning is the relationship between
cognitive functions and physical movement.
Psychomotor learning is demonstrated by physical
skills such as movement, coordination,
manipulation, dexterity, grace, strength, speed;
actions which demonstrate the fine motor skills such
as use of precision instruments or tools.
Behavioral examples include driving a car, throwing
a ball, and playing a musical instrument.
In psychomotor learning research, attention is given
to the learning of coordinated activity involving the
arms, hands, fingers, and feet, while verbal
processes are not emphasized.
