Psychology and computer science are clearly distinct disciplines. As we have seen, there are obvious differences within the definitions and methodological approaches of the two. Still, despite the differences, there are some interdisciplinary subfields that try to fuse the two.

An interdisciplinary perspective on the two disciplines is cognitive science, wherein the human mind is seen as an information processor, a machine. According to cognitive scientists, the mind sees information in the same manner as computers do. First, it receives ‘input’ from a source. Then, this input is stored on some kind of ‘hard drive’. Finally, the input will be processed. The results of this process is the ‘output’ (Friedenberg, Silverman, 2006: p. 3). The mental representation of information is thus a significant part of cognitive science, which can be compared with information processing on computers.

A field that draws upon this is human-computer interaction (HCI). HCI can be seen as a merge between cognitive psychology and programming aspects of computer science, to create well designed interfaces. According to Carroll, it looks at how humans interact with technology, and how that can be supported through the design. It came into being partly because of “the recognition that computers can be deliberately designed to facilitate human activity and experience only when social and cognitive requirements drive the design process throughout” (Carroll, 1997: p. 62, 79). Therefore, cognitive psychology should be considered for the design of computer systems.

Another example is artificial intelligence (AI), early mentioned as a subset of computer science. AI scientists try to build machines that can automatically make intelligent decisions. They try to do this at the level of intelligence of a human agent, which should lead to the fact that the machine can act in the same manner as humans (Friedenberg, Silverman, 2006: p. 320). The consideration of what this intelligent behaviour is, comes from psychology.
