Agenda:
o Issues in Development
o Neural Development
o Visual Development
Questions:
o What influences development?
o How does the brain change in the newborn?
o How does the visual system change over the first few months of life?
James-Lange theory: no arousal, then no emotions
Schachter’s theory, one can experience emotion without arousal, but the intensity of the
emotion might be lower
Lateralization
o In general, right hemisphere plays greater role than left
o Hauser (1993)
Emotions begin on the left side
Emotion is triggered on the left because of counter lateral control
At peak intensity greater expression on left
o Note:
Left frontal lobe more involved in positive emotions, right in negative
Humans remember negatives things better than positive things
More activity in left when watching happy films, more in right for sad/disgusting
films
Visible in 10-months old infants
Probably hardwired in the brain, pick up very easily
Development
o Change in abilities over time
What influences Development
o Nature vs. Nurture
o Maturation Learning
o Obviously -> interaction
Nature determines the range
Nurture chooses the alternatives
Stagelike Development
o Discontinuous… stages separated by rapid growth
o Qualitative difference
Each stage are different from each other

Document Summary

Issues in development: neural development, visual development. Schachter"s theory, one can experience emotion without arousal, but the intensity of the emotion might be lower. In general, right hemisphere plays greater role than left: hauser (1993) Emotion is triggered on the left because of counter lateral control. At peak intensity greater expression on left: note: Left frontal lobe more involved in positive emotions, right in negative. Humans remember negatives things better than positive things. More activity in left when watching happy films, more in right for sad/disgusting films. Probably hardwired in the brain, pick up very easily. Development: change in abilities over time. What influences development: nature vs. nurture, maturation learning, obviously -> interaction. Stagelike development: discontinuous stages separated by rapid growth, qualitative difference. Each stage are different from each other. E. g. caterpillar, its life cycle, in stages to become a butterfly. Look the same, do the same: quantitative difference. Adult can do things better than young ones,
