At which age do infants begin to walk?

6-8 months
11-15 months
9-10 months
16-18 months

Correct Answer

A. 11-15 months

Explanation

Infants typically begin to walk between the ages of 11-15 months. This is considered a normal developmental milestone, although the exact age can vary from child to child. At this stage, infants have developed enough strength and coordination to support their body weight and take their first steps. It is important to note that some infants may start walking earlier or later than this range, and both cases can still be within the normal range of development.

Which sense is the first to develop?

Chemosensation
Sight
Pain
Touch

Correct Answer

A. Touch

Explanation

The sense of touch is the first to develop because it is essential for survival and is present even before birth. The sense of touch allows us to perceive and interact with our environment, providing crucial information about objects, textures, and temperature. It plays a vital role in the development of the nervous system and helps infants bond with their caregivers. Additionally, touch is a primitive sense that is present in many organisms, indicating its early evolutionary development.

At what age in the womb do fetuses begin to suck/swallow amniotic fluid?

12 weeks
10 weeks
8 weeks
6 weeks

Correct Answer

A. 12 weeks

Explanation

Fetuses begin to suck/swallow amniotic fluid at 12 weeks. At this stage, the fetus's digestive system has developed enough to allow them to swallow the amniotic fluid, which helps in the development of their swallowing reflexes and the maturation of their digestive system. Before 12 weeks, the fetus is not yet capable of swallowing the amniotic fluid.

At what age can fetuses hear?

5-10 weeks
10-20 weeks
22-24 weeks
26-28 weeks

Correct Answer

A. 22-24 weeks

Explanation

Fetuses can hear at around 22-24 weeks. This is because by this stage of pregnancy, the structures of the ear have developed enough for the fetus to start perceiving sound. The cochlea, which is responsible for hearing, becomes functional around this time. Additionally, the auditory pathways in the brain also start to develop, allowing the fetus to process and respond to sound stimuli. Therefore, 22-24 weeks is the age at which fetuses begin to have the ability to hear.

When infants form a category on the spot it is known as:

Category development
Category creation
Category formation
Category possession

Correct Answer

A. Category formation

Explanation

Category formation refers to the process by which infants spontaneously create mental categories or groups based on their observations and experiences. This cognitive ability allows infants to organize and make sense of the world around them. It involves the ability to recognize similarities and differences between objects or events and group them together based on shared features or characteristics. Through category formation, infants begin to understand and classify various objects, actions, and concepts, which lays the foundation for their future cognitive development.

In which reflex does a baby extends/flex it's arms and legs when placed on it's back/stomach?

Rooting
Morrow
Labyrinthine
Grasping
Swimming

Correct Answer

A. Labyrinthine

Explanation

The correct answer is labyrinthine because the labyrinthine reflex is the reflex that causes a baby to extend or flex its arms and legs when placed on its back or stomach. This reflex helps the baby to maintain balance and posture while lying down. The other options listed are not related to this reflex and do not involve the extension or flexion of the arms and legs in response to being placed on the back or stomach.

What is the definition of agency?

Self is distinct
Gearing actions for the future
Finding new ways to get to one's goal
Means-ends problem solving

Correct Answer

A. Self is distinct

What is Piaget's 2nd stage of sensorimotor development?

Secondary circular reactions
Modification of reflexes
Beginnings of thought-mental representation
Primary circular reactions

Correct Answer

A. Primary circular reactions

Explanation

Piaget's second stage of sensorimotor development is characterized by primary circular reactions. During this stage, which typically occurs between the ages of 1 and 4 months, infants become more aware of their own bodies and begin to intentionally repeat actions that bring them pleasure or satisfaction. These actions are primarily focused on their own bodies and involve simple repetitive movements, such as sucking their thumb or kicking their legs. This stage marks an important milestone in the development of object permanence and the understanding that actions can have an effect on the environment.

In the embryonic stage of prenatal development:

The first cell divides in two.
Motor, sensory, learning originates.
The fetus experiences rapid growth.
The physical appearance of the embryo is clearly human.

Correct Answer

A. The physical appearance of the embryo is clearly human.

Explanation

During the embryonic stage of prenatal development, the physical appearance of the embryo becomes clearly human. This is because the embryo undergoes significant growth and development, with the formation of distinct human features and structures. The process of organogenesis occurs during this stage, where the major organs and body systems begin to develop. The embryo also starts to exhibit recognizable human characteristics, such as limb buds and facial features. This stage is crucial in shaping the overall physical appearance of the developing fetus.

What is the third stage of spatial and objects concepts?

Deferred circular reactions: infant's object oriented play activity was interrupted, then infant resumes act
Interrupted prehension: re-acquire an object when briefly out of sight
Reconstruction of an invisible whole from a visible fraction: retrieves object partially covered
Removal of obstacles preventing perception: pulls object away to recover x

Correct Answer

A. Deferred circular reactions: infant's object oriented play activity was interrupted, then infant resumes act

Explanation

The third stage of spatial and object concepts is deferred circular reactions. This stage involves the infant's object-oriented play activity being interrupted, and then the infant resumes the activity. This suggests that the infant is developing an understanding of cause and effect, as well as the ability to mentally represent and manipulate objects in their environment.

What happens in Piaget's 5th stage of sensorimotor development. tertiary circular reasoning?

Invents new means via mental representation, imagining what will happen mentally before trying it out
Novelty and exploration, deliberate trial and error
Coordinated and intentional, means to an end, there is an intentional goal in mind
Adjusts reflexes to meet needs in certain situations

Correct Answer

A. Novelty and exploration, deliberate trial and error

Explanation

In Piaget's 5th stage of sensorimotor development, which is known as tertiary circular reasoning, children engage in novelty and exploration. They actively seek out new experiences and engage in deliberate trial and error to understand the world around them. This stage is characterized by a sense of curiosity and a desire to experiment with different actions and outcomes. Through this process, children develop mental representations and can imagine what will happen before trying it out physically. They are able to use their cognitive abilities to plan and execute actions with an intentional goal in mind.
