Discuss positive and negative effects of modern technology on cognitive processes Flashcards
How has technology developed in the last century?
Technology has evolved enormously in the last century from computers for learning and working to video games for entertainment.
What have psychologists been asking?
With all of this change, psychologists have been asking whether all of this technology is good for us or not and therefore both positive and negative effects have been the subject of research.
Positive side of technology
On the positive side, some argue digital technology can enhance cognitive functioning
For example, video gaming can improve perception, mental rotation skills, visual memory, attention, task-switching, multi-tasking and decision-making.
Negative side of technology
On the negative side, some contend that digital technology can lead to distraction, reduced attention spans, a sense of social isolation, scattered thinking and a decline in the ability to think analytically
What cognitive process has been the focus of several investigation how the effect of technology?
Memory
First example of technology effect on memory
Search engines
Study on search engines
Sparrow et al
Aim of Sparrow et al
Were interested in how search engines might affect memory
What did Sparrow et al liken search engines to?
External memory sources accessible when information is needed.
In this way, digital technology is changing the way information is stored.
You may not remember the information, but you do know where you can find that information when necessary.
What were Sparrow et al confident about?
Were confident that memory is adapting to new computing and communication technology and they reached this conclusion after a series of experiments.
Procedure of Sparrow
The researchers showed participants trivial pieces of information, for example ‘an ostrich’s eye is bigger than its brain’.
These statements were then typed into a computer by the participants.
Half the participants believed what they typed would be saved while the other half were informed the information would be lost.
Results of Sparrow
Participants who believed the information would be lost recalled more statements than the participants who were told that the information would be saved.
Additional experiment from Sparrow
Additional experiments followed the same set of procedures but this time the computer responded either by saying ‘Your entry has been saved’, ‘Your entry has been erased’ or ‘Your entry has been saved to…’ followed by a folder name.
Each person was then shown a list of statements and asked two questions: ‘Have you seen this fact before?’, ‘Was this fact saved or deleted?’ or ‘Where was this fact saved?
Result of second experiment from Sparrow
When a fact had been flagged as one that the computer erased, participants had a better memory of the fact itself.
However, when the computer told them that the fact had been saved and where it had been saved, they more accurately remembered that it had been saved and where it had been saved compared to remembering the fact itself.
Conclusion of Sparrow
Based on these results the researchers challenged simplistic arguments that digital technology is detrimental to cognitive processes like memory.
