Dark side of technology Essay

The nature of these machines makes it possible for discrimination against common persons. Ordinary persons who may have a predisposition towards certain tendencies could be found out and victimised even though they have moreover to commit a crime they have the brain pattern of a criminal. This is the dark side of technology. more than research is needed to determine whether or not there be differences between criminals and ordinary persons. at that place is mode for these tests to be manipulated by either the prosecution or the defence. Which ever team pays for the tests can get the results that they so desire.Over sensitivity of the machinery needs to be controlled for in the tests in order for their reliability to be increased, and their usefulness enhanced.More research needs to be done to determine if there atomic number 18 genuine differences between the brains of criminals and ordinary persons.If the tests are genuinely able to gather up differences between criminals and ordinary persons then maybe abnormalities can be controlled for originally criminal behaviour is expressed.DeregowskiDepth Cue- Depth cues are (hints, guides, cues) which provide tuition about the spatial (positioning relative to each other) relationships among objects (three dimensional) in a usher (two dimensional).Familiar Size- The cue whereby objects, which are further away in the picture, are drawn smaller than objects of the same size which are closer.Overlap Cue- The moment of a nearer object obscuring parts of a more inappropriate object.Perspective- This is given by the convergence of lines depicting edges which are parallel in the real world, but which appear to come together as they depart into the distance e.g. a railway track.A person using a depth cue will extract a completely various meaning from a picture than will a person who is not using such pictures.Various drawings of an elephant, an antelope, a person, a tree, a road, some(prenominal) hills and a flyi ng bird were shown.Empirical TestThe tests are a posteriori because numeric information was collected. How many persons made different responses e.t.cThese tests involved screening pictures and asking questions. What do you see?What is the man doing?Which is nearer the antelope or the elephant?methodological analysisThe questions were asked in the subjects, native language. This means the results were not affected by amazement resulting from the use of the interviewers language or from translations. They understood exactly what they were being asked.There was a potential problem with classification. If questions were answered correctly according to Hesperian standards it was mechanically assumed that they were three dimensional perceivers. This could have impacted upon the results.The tests may not have been measuring cultural differences as noted but instead, educational and affable levels. Evidence for this is provided by persons of better educational and social levels perfo rm better on the tests. Remember children have better access to western culture and education than do adults. Additionally higher educational and social levels provide persons with access to western culture.Deregowski reviewed Hudsons work and put ahead some different opinions. This means the results could have been a consequence of interpretation.The count includes information from different term periods. The results may have been as a result of this time elapse. For e.g. the info collected from Zambian school children-information was presented from some(prenominal) 1960 and 1972. There culture and circumstances may have changed tremendously during the time elapse.Adults and children were differentiated. Therefore a comparison could have been made to take into aim changes in culture. Note Hudson found that children had higher rates of three dimensional perception than did adults. note-Deregowski found that both adults and children had difficulties making three dimensional perc eptions ecologic ValidityThe Subjects may have been put in artificial categories which were a consequence of the test-three dimensional and two dimensional perceivers.Persons are not unremarkably required to view pictures under these conditions (circumstances) as existed during the study.The tests may have been pickaxe up differences in educational and social levels and not culture as was suggested.
