Where is problem solving in the brain




















While it is possible that the solver arbitrarily arrived at the goal in a diffused problem space and without conscious awareness of completing the task or even any converging event or problem recompiling, it appears somewhat unlikely. It is true that there are many tasks that we complete without actively thinking about it. We do not think about what foot to place in front of another while walking, but this is not an instance of problem solving. Instead, this is an instance of unconscious task completion.

The model predicts that a problem cannot return to a focused mode without some amount of restructuring. That is, once defocused, the problem is essentially never the same again.

The problem elements begin interacting with other internally and externally-generated items, which in turn become absorbed into the problem representation. This prediction can potentially be tested by establishing some preliminary knowledge, and then showing one group of subjects the same knowledge as before, while showing the another group of subjects different stimuli.

If the model's predictions hold, the problem representation will be restructured in some way for both groups. There are numerous other such predictions, which are beyond the scope of this paper.

One of the biggest challenges then becomes evaluating the model to set up suitable experiments aimed at testing the predictions and falsifying the theory, which I address next. One of challenges in evaluating the RWPS is that real world factors cannot realistically be accounted for and sufficiently controlled within a laboratory environment. At the expense of ecological validity, much of insight problem solving research has employed an experimental paradigm that involves providing participants single instances of suitably difficult problems as stimuli and observing various physiological, neurological and behavioral measures.

In addition, through verbal protocols, experimenters have been able to capture subjective accounts and problem solving processes that are available to the participants' conscious. One challenge with this paradigm has been the selection of a suitable set of appropriately difficult problems. The classic insight problems e. Some in the insight research community have moved in the direction of verbal tasks e. Unfortunately, these puzzles, while providing a great degree of controllability and repeatability, are even less realistic.

These problems are not entirely congruent with the kinds of problems that humans are solving every day. The other challenge with insight experiments is the selection of appropriate performance and process tracking measures. Most commonly, insight researchers use measures such as time to solution, probability of finding solution, and the like for performance measures. For process tracking, verbal protocols, coded solution attempts, and eye tracking are increasingly common.

In neuroscientific studies of insight various neurological measures using functional magnetic resonance imaging fMRI , electroencephalography EEGs , transcranial direct current stimulation tDCS , and transcranial magnetic stimulation tMS are popular and allow for spatially and temporally localizing an insight event. Thus, the challenge for RWPS is two-fold: 1 selection of stimuli real world problems that are generalizable, and 2 selection of measures or a set of measures that can capture key aspects of the problem solving process.

Unfortunately, these two challenges are somewhat at odds with each other. While fMRI and various neuroscientific measures can capture the problem solving process in real time, it is practically difficult to provide participants a realistic scenario while they are laying flat on their back in an fMRI machine and allowed to move nothing more than a finger.

To begin addressing this conundrum, I suggest returning to object manipulation problems not all that different from those originally introduced by Maier and Duncker nearly a century ago , but using modern computing and user-interface technologies. One pseudo-realistic approach is to generate challenging object manipulation problems in Virtual Reality VR.

VR has been used to describe 3-D environment displays that allows participants to interact with artificially projected, but experientially realistic scenarios. It has been suggested that virtual environments VE invoke the same cognitive modules as real equivalent environmental experience Foreman, However, a VR-based research approach has its limitations, one of which is that it is nearly impossible to track participant progress through a virtual problem using popular neuroscientific measures such as fMRI because of the limited mobility of connected participants.

Most of the studies cited in this paper utilized an fMRI-based approach in conjunction with a verbal or visual task involving problem-solving or creative thinking. Very few, if any, studies involved the use physical manipulation, and those physical manipulations were restricted to limited finger movements.

Thus, another pseudo-realistic approach is allowing subjects to teleoperate robotic arms and legs from inside the fMRI machine. This paradigm has seen limited usage in psychology and robotics, in studies focused on Human-Robot interaction Loth et al. It could be an invaluable tool in studying real-time dynamic problem-solving through the control of a robotic arm.

In this paradigm a problem solving task involving physical manipulation is presented to the subject via the cameras of a robot. The subject in an fMRI can push buttons to operate the robot and interact with its environment. While the subjects are not themselves moving, they can still manipulate objects in the real world. What makes this paradigm all the more interesting is that the subject's manipulation-capabilities can be systematically controlled.

Thus, for a particular problem, different robotic perceptual and manipulation capabilities can be exposed, allowing researchers to study solver-problem dynamics in a new way. For example, even simple manipulation problems e. Here, the problem space restrictions are imposed not necessarily on the underlying problem, but on the solver's own capabilities.

Problems of this nature, given their simple structure, may enable studying everyday practical creativity without the burden of devising complex creative puzzles. Crucial to note, both these pseudo-realistic paradigms proposed demonstrate a tight interplay between the solver's own capabilities and their environment. While the neural basis for problem-solving, creativity and insight have been studied extensively in the past, there is still a lack of understanding of the role of the environment in informing the problem-solving process.

Current research has primarily focused on internally-guided mental processes for idea generation and evaluation. However, the type of real world problem-solving RWPS that is often considered a hallmark of human intelligence has involved both a dynamic interaction with the environment and the ability to handle intervening and interrupting events.

In this paper, I have attempted to synthesize the literature into a unified theory of RWPS, with a specific focus on ways in which the environment can help problem-solve and the key neural networks involved in processing and utilizing relevant and useful environmental information. Understanding the neural basis for RWPS will allow us to be better situated to solve difficult problems.

Moreover, for researchers in computer science and artificial intelligence, clues into the neural underpinnings of the computations taking place during creative RWPS, can inform the design the next generation of helper and exploration robots which need these capabilities in order to be resourceful and resilient in the open-world.
