in one well-known study, kahneman et al. (1990)presented a coffee mug with a university logo on it to one group of participants (“sellers”) and told them the mug was theirs to keep, then asked these participants whether they would sell the mug back to them at various prices. a second group of participants (“choosers”) were told that they could have the option of receiving an identical mugor an amount of money and were asked which they preferred at various prices. although both groups were placed in strategically identical situations (walk away with a mug or money), the sellers, who presumably framed the choice as a loss of a mug against a compensating gain of money, quoted a median price of $7.12, whereas the choosers, who presumably framed the choice as a gain ofa mug against a gain of money, quoted a median price of$3.12.

participating high school students first interacted with an interviewer who asked a series of questions. for one of the questions, the interviewer acted in either an “unkind”or a “neutral” way. in the next part of the experiment, students were presented with the choice of approaching one of two new experimenters, one of whom physically resembled the first interviewer. only 20 percent of students who had had an unpleasant brief encounter during the interview approached the experimenter who physically resembled the interviewer, whereas 57 percent of students who had had a neutral interaction with the interviewer chose the physically similar experimenter. it can be inferred from the result that even a single previous contact is capable of influencing a choice at the present day.

in addition, if you choose a higher sampling rate with less or no compression, a digital recording can come extremely close to accurately mirroring the original sound.

one of the great things about digital recordings is that they don’t deteriorate. remember how those old lps would start to hiss and crackle after several playings? not so with digital media. (①) those 1s and 0s remain 1sand 0s throughout the entire process. (②) physically, this means that the music on a cd sounds exactly the same after a thousand playings as it did when first out of the jewel case. (③) it’s the same with digital downloads; the thousandth digital copy of a song will sound identical to the original. (④) analog recording scan also be accurate, but are frequently plagued by a low signal-to-noise ratio because of high background noise. (⑤) digital recordings have a very high signal-to-noise ratio, with very little background noise or distortion.
