Then you get refinement of fingers and toes and sensory organ in what stage? Fetal stage
The age of viability (the earliest a baby can be born and still survive) is.... 20 to 28 weeks
What is the term for this: when there is one cell to begin with and it begins to divide and divide and divide and keeps dividing and what stage is it in? Cell division, in Zygote stage
Up to 30% fail to pass the _______ stage? Zygote

.By the time children are born they have already undergone some learning - how do we know this? = one way is by looking at the intervals between their s________ ________? Sucking bursts
So the experiment that looked at IBI (interburst interval) where child is read story while in the womb and after they are born half babies are read familiar story (reward) if they i_________ IBI and half are rewarded if d_________ IBI. Whats this testing? increase, decrease. Testing whether babies have undergone learning before they are born.
What were the results of this mother reading story study? The babies who had been read to while they were in the womb would change their sucking bursts in order to hear the same/familiar story again. This was true whether the baby had to reduce their IBI or increase their IBI
"The babies who had been read to while they were in the womb would change their sucking bursts in order to hear the same/familiar story again. This was true whether the baby had to reduce their IBI or increase their IBI" What does this mean? That the babies are learning while they are in the womb
This idea of babies learning a story in the womb means that their h_______ must be pretty good hearing
What are the four ways of gathering evidence from new-born babies? Heart-rate decelerations, Food preference, Object preference and Habituation (Now read over this in notes)
What concept is this referring to? "in general babies prefer novelty things. If you hold up keys the baby will look for 30 seconds initially and then next time will look for 10 seconds" Habituation
Read through the studies on page 5 and 6 and make summary pages for them. ...

The cones in a baby are different from those of an adults - they are different shape and __________ density
What is this referring to? "agreement that this colour is red and how there is a point where red now becomes orange - knowing the categorical boundaries)" Categorical colour perception

What type of depth cue is this referring to? "If he takes an object and approaches you with the object, you perceive depth because this object is getting larger in your visual field. So you know that it is closer" Optical expansion
At one month infants show awareness of optical expansion depth cue because if you take an object and move it quickly towards them they will ________? blink
What depth cue is this? " you have two eyes and each are perceiving objects in the world at a slightly different angle - if you more up close, it gives you more cues to what te depth is. By 4 months babies are capable of using these cues" Stereopsis
What depth cue is this? "we know that that object is further away because the other one is obscuring it - we can only see a portion of the other one so therefor we know that the other one is closer" Monocular cues
What depth cue is this referring to? "the size of the object is a clue to how close it is to you" Optical expansion
Which depth cue is this referring to? " the child reaches to the longer trapezoidal window indicating that the baby sees it as the nearer side taking into account relative size" Monocular cues
Babies have a number of reflexes and these __________ as cortical control increases weaken

What principle of motor control is this? From head to tail Cephalocaudal trend
What principle of motor control is this? "the upper portion of the body develops quicker than the lower part of the body" Cephalocaudal trend
What principle of motor control is this? "the middle part of the body develops quicker than the outer part of the body" Proximodistal trend
What principle of motor control is this? "the one month olds head and trunk are larger in proportion to the legs and arms" Proximodistal trend
With boys and girls, most of their development is pretty much parellel. True or false? True, they develop similarly with average heights and average weights the same for both genders
What principle of motor control is this? "When you look at the size a babies head, it's very large relative to the rest of the body. If you look at an adult the head is much smaller. So the upper portion of the babies body is developing much more quickly" Cephalocaudal trend

One mechanism of change is changes in body proportions which helps the baby to get around and walk. True or false? True
What mechanism of change is this? "as the baby begins to look at your eyes and mouth, they have increased motivation for social contact as now the baby is taking in the emotional information that you are conveying to them via your eyes and mouth" Motivation
