Psych 2ap3- oct 2nd Flashcards
How was cognitive flexibility measured?
Child-friendly stoop task
What is the child-friendly stoop task?
They will show a picture of something (eg: a cat, and then make a noise (eg: meow) and the child has to connect that sound to a given picture by the sound, not picture
How were irritability and cognitive flexibility associated?
Irritibility and cognitive flexibility were not directly correlated. Just because someone is irritable, that does not mean they are going to do bad on the stoop task
What was correlated in the troop task?
The neural activation of (dorsolateral prefrontal cortex) and irritability were positively correlated. Cognitive flexibility was also associated with neural activation (more active cortex= better cognitive flexibility)
Why do humans move?
As a means to solve a solution
What is the general pattern for posture for humans (how long it takes to support themselves)
2 months: head erect
6-7 months: sit independently
8-9 months: pull one self up
10-12 months: stand alone
Very variable
What are fine motor skills?
fine-tuned movements requiring finger dexterity
When/how do fine motor skills start?
0-2 years, grasping and reading for objects
In terms of fine motor skills, what can children around 18-24 months of age do?
Build towers
How was William James vs Piaget’s view on newborn perception different?
William James: baby feels sensations all at once, very confusing
Piaget: sensations by baby are impoverished, they try to piece together information using their senses (try to distinguish familiar senses vs non familiar senses)
what are the 4 ways in which babies’ sensory and perception is tested?
- operant conditioning
- preference paradigm
- violation of expectations paradigm
- habituation/dishabituation
How was visual acuity and contrast sensitivity measured in new borns and what paradigm was this?
Grey-bar experiment, preference paradigm (should prefer grey bars over a blank grey square)
What was found through the grey bar experiment/what factors were tested?
visual acuity in new borns 30x worse than adults and contrast sensitivity is 20-25x worse
What are new born vision deficits?
- visual acuity
- contrast sensitivity
- convergence
-coordination - colour perception
What can new borns actually tell/see?
Facial contours
