October 20, 2009 *****DICUSSION DUE ONE WEEK FROM TODAY INSIGHT PROBLEMS - A mix of inductive and deductive reasoning * Non-insight problems (Gradual progress) Problems require series of steps whose difficulty can be assessed Ability to predict solvability of problem * Insight problems (“Aha experience”) Problems   require   crucial   breakthrough   that   gives   a   new   perspective   on   the  problems Solvability can hardly be predicted e.g. Jessie and Mary were born on the same day of the same month of the same year  to the same mother and the same father – yet they are not twins. How is that possible? Solution: they are triplets e.g. The Nine-dot problem – draw four continuous straight lines, connecting all the dots  without lifting your pencil from the paper or retracing any line. MENTAL SET Why couldn’t you solve the previous problems? Mental Set      – a well-established habit of perception or thought Same   problem   when - believing that the medication will not work and ignoring the doctor’s advice to  take   the   medication -   revise   our   own   papers - our e.g.: most people will not draw lines that extend from the square formed by  the nine dots Solution to solving these sorts of problems is to abandon a mental set THE TWO-STRING PROBLEM You enter a room in which 2 strings are hanging from the ceiling. Your task is to tie the  string together. Unfortunately, the strings are positioned far apart so that you cannot  grab   of   them
