PSYC 304 Chapter Notes - Chapter 9: Skipping Rope, Body Image, Asthma
Document Summary
Children with deficits often do not catch up. Running and turning, walking heel to toe, jump rope. Pruning of unused synapses contributes to increases in motor speed and reaction time. Low socioeconomic status can lead to poor access to health care, poor nutrition, and stressful home and neighborhood environments. Capacity to use logic to solve problems but still are unable to apply logic to abstract and hypothetical situations. Non-western cultures achieve conservation and other concrete operational tasks later. Describes development as entailing changes in the efficiency of cognition rather than qualitative changes in reasoning. Sample items measuring the four wechsler intelligence scale for children indices. Working memory index (wmi): digit span: children are read lists of numbers and asked to repeat them as heard or in reverse order. Processing speed index (psi): coding: in this timed task, children are shown a code that converts numbers into symbols and are asked to transcribe lists of numbers into code.
