Perspectives in Biology and Medicine

Psychology does not go on in a social vacuum. Behavior changes over time, and over different situations. These factors, and individual differences, make research findings reliable for a limited time only. Are traditional scientific methods appropriate for studying human behavior? When psychologists operationalize their IV, it is highly likely that this is reductionist, mechanistic, subjective, or just wrong. Experiments are keen to establish that X causes Y, but taking this deterministic view means that we ignore extraneous variables, and the fact that at a different time, in a different place, we probably would not be influenced by X.

Simeon Locke (Author of Schizophrenia And Consciousness)

There are so many variables that influence human behavior that it is impossible to control them effectively. The issue of ecological validity ties in really nicely here. Objectivity is impossible. It is a huge problem in psychology, as it involves humans studying humans, and it is very difficult to study the behavior of people in an unbiased fashion. Moreover, in terms of a general philosophy of science, we find it hard to be objective because we are influenced by a theoretical standpoint Freud is a good example of this. The observer and the observed are members of the same species are this creates problems of reflectivity.

A behaviorist would never examine a phobia and think in terms of unconscious conflict as a cause, just like Freud would never explain it as a behavior acquired through operant conditioning. This particular viewpoint that a scientist has is called a Paradigm Kuhn, Kuhn argues that most scientific disciplines have one predominant paradigm that the vast majority of scientists subscribe to.

Anything with several paradigms e. With a myriad of paradigms within psychology, it is not the case that we have any universal laws of human behavior, and Kuhn would most definitely argue that psychology is not a science. Verification i. It could be disproved at any moment. The main driving force behind this particular grumble is Karl Popper, the famous philosopher of science and advocator of falsificationism.

Take the famous Popperian example hypothesis: "All swans are white". How do we know for sure that we will not see a black, green or hot pink swan in the future? So even if there has never been a sighting of a non-white swan, we still haven't really proven our hypothesis.

Popper argues that the best hypotheses are those which we can falsify - disprove. If we know something is not true, then we know something for sure. Testability: much of the subject matter in psychology is unobservable e. The fact that there are so many variables that influence human behavior that it is impossible to control the variables effectively. So, are we any closer to understanding a what science is, and b if psychology is a science? There is no definitive philosophy of science, and no flawless scientific methodology.

When people use the term "Scientific" we all have a general schema of what they mean, but when we break it down in the way that we just have done, the picture is less certain.

The Neuroscience of Consciousness

What is science? It depends on your philosophy. Is psychology a science? It depends on your definition. So - why bother, and how do we conclude all this? If we abandon our search for unified methods, we'll lose a sense of what psychology is if we knew in the first place. McLeod, S. Psychology as a science. The different sense of self at distinct points in time is henceforth associated with different persons or ego resulting in what psychopathology describes as egodisorder. Although tentative and speculative to a certain degree , this hypothesis can nevertheless be tested by linking mental time travel to self-related paradigms: one would expect that reduced midline neural activity during mental time travel predicts the degree of reduced self-related processing and subsequently the degree of egodisorder in schizophrenic patients.

However, other symptoms like egodisturbances remain unexplained. What do we gain clinically from the suggested neurophenomenal hypotheses? Secondly, the specification of neurophenomenal relationships on both sides neurally and phenomenally may make possible the development of different diagnostic markers for the various phenomenal abnormalities and psychopathological symptoms in schizophrenia.
