I. Piaget’s Stage 3: Concrete Operational Thought A. What is Concrete Operational Thinking? 1. Children in Middle Childhood, Stage 3 Concrete Operational Thought a. Decentered Thoughts consider multiple aspects of problems b. Focus on Dynamic Transformations in problem ie: while infants think that the taller liquid of 2 flasks has more liquid, they can consider changes in height, weight, volume, etc c. Show Reversibility of true mental operations can consider how processes would be if reversed d. Operational cognitive structures B. Class inclusion, Seriation, and Transitive Inference Skills 1. Can understand Class Inclusion problems, the idea that objects can be classified in different ways and at different levels a. Ie: if u show 5 dolls and 3 bears and ask “are there more dolls or more toys?” they will know that dolls are toys 2. can Seriate , or arrage a set of items according to a quantitative dimension (ie: size, weight, length) 3. show Transitive Inference , process of mentally drawing inferences by comparing relations a. ie: can solve: Sue is taller than Jean, Jean is taller than Lexi, who is taller, Sue or Lexi? 4. use true operational logic can correctly represent logical relationships C. Where they are not developed 1. use of mental operations limited to concrete objects or situations a. aka can’t use mental operations w/o direct experience or if material is not tangible D. Theory of Mind 1. age 4: can take perspective of another, but confused in complex situations 2. age 6-7: can take perspective of 2 different ppl, but not “third person” perspective 3. age 10-12: can take the 3 rd person perspective II. Information Processing: Memory Development A. Stores Model- memory moving through series of storage locations 1. info enters cognitive system via the Sensory Store , where large amts of info can be maintained 4 brief periods (1/2 a second) 2. some info in sensory store passed 2 Short-Term Store (STS) a. STS contains info ur consciously aware of at given moment b. STS capacity= limited, can only hold btw 5-10 “chunks” info c. Chunking : process of recording individual elements in memory into large groups of info d. Info in STS can only stay in memory 4 long time periods if we actively attend 2 it 3. info that is stored permanently passes to Long-Term Store (LTS)

a. LTS=infinite storage capacity b. Info remains here permanently, even if not actively attended 2 4. an Executive Processor manages all 3 stores a. processes the info that passes among them b. decides which info will be attended to B. Networks Model - memory is an interconnected network of associated info 1. memory separated by concept nodes connected by links a. links vary in strength b. more heavy the link is stronger association btw nodes 2. info can be activated at different degrees at any time a. higher level activation info is easier 2 remember b. ie: your own name 3. nodes can be activated through external sources (seeing an object) or
