On Dr. Eshlemann’s opposition to probability

Recently an interesting post came to my attention authored by the late Dr. John W. Eshlemann entitled “Junk Behaviorism”. Dr. Eshlemann criticised the phrase that reinforcement increases the probability of behavior while advocating the use of rate of response. As I had previously frequently employed the word “probability” (e.g. Introduction to radical behaviorism (Part 4 – Operant conditioning, new traits/behavior).), I was compelled to reflect on the matter.

A variation of this misconception [lack of clarity about what a reinforcer does] is that “reinforcement” “increases the probability of behavior,” or that it “increases the likelihood of behavior.” While slightly better than the even more ambiguous “increases behavior,” these still qualify as bad phrases; phrases that obscure more than they clarify. In contrast, Skinner was very clear: a reinforcer affects the RATE OF RESPONSE. More specifically, a reinforcer increases the frequency of behavior over time, where frequency refers to, and means the exact same thing as, rate of response.

To get a rate of response you have to COUNT instances of behavior and determine how many there are per unit of time. You need to determine the frequency of behavior and then see whether that frequency changes over time. If it does, and if it increases, then you begin to have some evidence that the event, or thing, functioned as a reinforcer.

In terms of probability and changes to probability, Skinner was always very clear: Probability referred to rate of response. This type of probability addresses the “how often?” question, not the “what are the odds?” question. If we loosely say that the “probability of the behavior increases,” in Skinner’s science we really mean that the response rate increased over time. The count per minute went from one level up to another level. For example, if we start “reinforcing” behavior, it’s frequency might increase from 5 per minute up to 20 per minute. Or, perhaps behavior increases from .1 responses per minute up to .5 responses per minute. If, but only if, those sorts of increases in response rate occur, do we begin to have evidence that we have reinforcement.

Dr. John W. Eshlemann (2008) – Charting versus “Junk Behaviorism” – https://jweshleman.wordpress.com/2008/11/02/charting-versus-junk-behaviorism/

Relation between probability and rate of response

Somewhat contrary to Dr. Eshlemann’s stance, the subject isn’t clear-cut. In Skinner’s works, the word probability appears regularly and often separately from rate of response. After all, not all behaviors appear in repeatable form. Determining the primacy of the two concepts in Skinner’s science was a question previously visited:

In summary, Skinner’s position on the relation between response probability and response rate seems to be that although the two are not equivalent, response probability can be inferred from response rate.

In any event, Skinner remains clear that the concept of probability plays a central role in his science of behavior: “If we are to predict behavior (and possibly to control it), we must deal with probability of response”, and “The end datum in a theory of behavior, in short, is the probability of action”.

Johnson & Morris (1987, p. 117) – When Speaking of Probability in Behavior Analysis

Reinforcement by definition affects the rate of behavior (in specific circumstances, of a specific behavior class). Can we actually gain anything by referring to probability?

Our basic datum is the rate at which such a response is emitted by a freely moving organism. This is recorded in a cumulative curve showing the number of responses plotted against time. The curve permits immediate inspection of rate and change in rate. Such a datum is closely associated with the notion of probability of action.

Ferster & Skinner (1957, p. 18) – Schedules of Reinforcement

Rate of response as the dependent variable

One must consider that a specific rate of response / frequency can actually be selected. In Science and Human Behavior (1953) this idea is presented when speaking about so-called combined schedules, albeit in an ironically unfortunate way (remember behavior is reinforced, not an organism):

We can reinforce an organism only when responses are occurring at a specified rate. If we reinforce only when, say, the four preceding responses have occurred within two seconds, we generate a very high rate.

B.F. Skinner (1953, p. 105) – Science and Human Behavior

Furthermore, in Ferster & Skinner (1957) – Schedules of Reinforcement, there is a whole chapter dedicated to the topic – Chapter 9: Differential Reinforcement of Rate. To illustrate, let’s say we want a rat to push a lever at a rate of 5 times per minute – so if a rat is too fast initially, we reinforce behavior when it slows down. While Dr. Eshlemann mentioned only the possibility of the rate of response increasing, but one would think that he wouldn’t mind us saying that the reduction of the rate of response may also indicate learning.

In this case, rather than rate of response, we may meaningfully employ probability by a careful definition of calculation – e.g. the percent of 1-minute intervals where the rat pressed the lever 5 time.

Celeration charts

I’m in no way arguing against the use of rate of response / frequency – it is by far the most pragmatic datum of behavioral science. Rate of response can be conveniently plotted in celeration charts while probability does not succumb so easily to charting. Now, knowing Dr. Eshlemann’s lifelong work with celeration charts, we might just have an idea what influenced his strongly pragmatic point of view.

The spectre of reification

Perhaps, when speaking of probability, we’re dangerously close to committing the error of reification, which is discussed in Johnson & Morris (1987). One should note a similar issue in Cognitive Psychology where behavior can be considered as a referent to some other more important processes:

A focus on behavior must not obscure the fact that even the definition and selection of a behavior unit for study requires grouping and categorizing. In personality research, the psychologist does the construing, and he includes and excludes events in the units he studies, depending on his interests and objectives. He selects a category—such as “delay of gratification,” for example—and studies its behavioral referents.

Mischel (1973, p. 268) – Toward a Cognitive Social Learning Reconceptualization of Personality

Skinner claimed that behavior is no referent but rather itself the object of science. Applying the analogy, shall we claim that the datum is the rate of response and it there is no need to consider it a referent for probability? Or maybe probability is the rare theoretical construct that is allowed in behavioral science?

Rate of responding appears to be the only datum that varies significantly and in the expected direction under conditions which are relevant to the “learning process.” We may, therefore, be tempted to accept it as our long-sought-for measure of strength of bond, excitatory potential, etc. Once in possession of an effective datum, however, we may feel little need for any theoretical construct of this sort. Progress in a scientific field usually waits upon the discovery of a satisfactory dependent variable. Until such a variable has been discovered, we resort to theory. The entities which have figured so prominently in learning theory have served mainly as substitutes for a directly observable and productive datum. They have little reason to survive when such a datum has been found.

It is no accident that rate of responding is successful as a datum, because it is particularly appropriate to the fundamental task of a science of behavior. If we are to predict behavior (and possibly to control it), we must deal with probability of response.

B. F. Skinner (1950, p. 7) – Are Theories of Learning Necessary

In closing, probability may have it’s place in behavioral science, but we should treat it carefully by not distancing ourselves from the object of study that is behavior:

The speaking of “probability” in behavior analysis is no different. In keeping it uncompromised: “There is only one rule, namely: that the descriptions should fit the events being described (Kantor, 1941, p. 48).

Johnson & Morris (1987, p. 125) – When Speaking of Probability in Behavior Analysis

Rate of responding is not a “measure” of probability but it is the only appropriate datum in a formulation in these terms.

Radical behaviorism

Psychology is a pseudoscience

The philosophy of radical behaviorism and the science of behavior leaves one with a major question – what is the status of psychology? What is the scientific standing of this field? How to interpret the widespread and popular explanations of behavior? In this post, I shall argue that psychology is not and cannot be considered a science.

Definition and subject matter

Let’s start at the very foundation. Psychology is defined as the study of the mind and behavior – such a definition is provided by the APA (American Psychological Association). Therein lies a major problem and we must critically evaluate the concept of the mind. Despite being the object of study, it is impossible to properly define – we cannot find a physical existence of such a thing beyond naming the conditions under which we utter the word mind.

What makes psychology pseudo-scientific is not the methods employed but it’s philosophy and subject matter. The field is marred with similar reifications, unnecessary and unworkable ideas for scientific analysis. All in all, psychology still remains in the 17th century pre-scientific Cartesian mind-body dualism.

Under closer inspection one can see, that most concepts employed in psychology are created seemingly out of thin air, while observable and measurable behavior serves as a proxy for supposed inner workings. Ideas are liberally and often uncritically borrowed from folk psychology. To illustrate the point, let us visit Chomsky’s and Mischel’s views:

Behavior is evidence. It’s not what you are studying; what you are studying is competence, capacity. If you study man’s insight you want to know what is going on in his brain; behavior gives the evidence for that. But the study of behavior is like calling physics ‘‘meter-reading science’’ because meter readings are the data. But in a serious field, you wouldn’t identify the subject with the study of the data.

Noam Chomsky in Virue´s-Ortega (2006, p. 245) – The Case Against B. F. Skinner 45 Years Later – An Encounter With N. Chomsky

Now the term “behavior” has been expanded to include virtually anything that an organism does, overtly or covertly, in relation to extremely complex social and interpersonal events. Consider, for example, “aggression,” “anxiety,” “defense,” “dependency,” “self-concepts,” “self-control,” “self-reinforcement.” Such categories go considerably beyond self-evident behavior descriptions. A category like aggression involves inferences about the subject’s intentions (e.g., harming another versus accidental injury) and abstractions about behavior, rather than mere physical description of actions and utterances.

Walter Mischel (1973, p. 268) – Toward a Cognitive Social Learning Reconceptualization of Personality

Both authors are conditioned to speak about things beyond behavior. Mischel seemingly does not recognize that formation of verbal behavior depends on individual history and also that nouns do not necessarily signify the physical reality of the word. Chomsky stumbles when identifying the proper subject matter of behavioral science – in a “serious field” one shouldn’t go around conjuring things. Skinner has a recommendation:

But the really great oversimplification is the traditional appeal to states of mind, feelings, and other aspects of the autonomous man which a behavioural analysis is replacing. The ease with which mentalistic explanations can be invented on the spot is perhaps the best gauge of how little attention we should pay to them.

B. F. Skinner (1971, p. 157) – Beyond Freedom And Dignity

Stated succinctly, psychology has pseudo-scientific features – non-natural phenomena are allowed, the natural history of an individual organism is not adequately considered and often ignored, teleological as well as inner agent/free-will statements are common and the sheer quantity of terminology is unmanageable. For this last point, one can simply review some studies of cognitive psychology and count the listed number of concepts, to name a few – motivation, emotions, feelings, memory, goals, personality, depression, self-efficacy, confidence, consciousness, instinct etc. No scientific philosophy is in such a milieu possible.

One must note that the application of the scientific method does not make a field a science. Astrology, for example, might employ some scientific methods, observe movements of the celestial bodies, demonstrate accurate star charts, but we are not misled by these. Besides, a part of psychology called behavior analysis that actually follows radical behaviorist principles is undeservedly undervalued – operant principles are granted only a small role in behavior explanation. This impedes the evolution of the field considerably.

Another bizarre feature of psychology is its relation to animal studies, that can fittingly be called a schism. Psychologists most often display an allergy to generalize findings found in animal studies to humans. Actually, the reverse has become more preponderant – we see a frenzy of anthropomorphisation (e.g. bees and numbers“We’ve learned bees can understand zero and do basic math, and now a new study shows their tiny insect brains may be capable of connecting symbols to numbers.”). Furthermore, how does the idea of the mind, an anthropocentric concept, contribute in understanding animal behavior?

A science of behavior in contrast, is a subdivision of biology, and no critical problems arise when comparing animal and human behavior. One can argue that fundamental behavioral principles are not to be studied in humans because sufficient control of all the historic variables is not possible. Furthermore, genetic studies have model organisms such as e. coli bacteria, yeast, roundworms, thale cress plant, fruit fly, zebrafish, mice; correspondingly behaviorology has Thornidikian cats, Pavlovian dogs and Skinnerian mice and pigeons – animal studies help us establish general principles of both genetics and behavior.

Circularity

The importance of the following point is so great, that it has to be stressed – most psychological explanations and concepts are circular in nature. Take intelligence for example. High intelligence allegedly explains behavior such as high scores for aptitude tests, but the only way to know that a person has a high intelligence are the same aptitude tests:

Not only do psychologists describe their subject matter in non-parsimonious—mentalistic—terms, they explain the behavior they do observe as being caused by the very cognitive processes they can never observe or measure. Such explanations are circular (Skinner called them explanatory fictions) in that the only evidence of the cognitive processes is the very behaviors they are trying to explain in the first place. When we are given circular explanations, we are being bamboozled into thinking that the behavior has been explained when it hasn’t. Or as Skinner has written, such explanations function to “allay curiosity and to bring inquiry to an end.”

Criteria of science

Referring to another article, 5 criteria are named for a field to be considered a science. They are:

  1. Clearly defined terminology
  2. Quantifiability
  3. Highly controlled experimental conditions
  4. Reproducibility
  5. Predictability and testability

Psychology does not meet the 5 criteria for a field to be considered scientific. We already visited the terminology issues. The problem of quantifiability naturally follows the undefinable concepts. Regarding the other points, control in human studies is often limited, historical variables are not adequately considered and self-report correlational studies are generally of dubious value. Moreover, psychology and social sciences are perpetually experiencing a reproducibility crisis. The cumulative nature of science in psychology is hardly to be found.

Due to the paucity of meaningful enduring results of psychological research, psychology has never condensed into a consistent, monolithic field. Therefore no proper foundation to psychology exists and it is illustrated by lack of proper introductory materials with textbooks being hodgepodge collections of different subjects with completely different terminology e.g. David Myers – Psychology:

In the typical introductory textbook, each chapter covers one of the various subfields of psychology. Collectively, the chapters provide a broad survey of topics, but in a way that is more patchwork than coherent. There is no overarching framework to organize and integrate the chapters, no basis for treating some material as basic and other material as derivative or advanced. Each chapter is self-contained, presenting its material in terms of the distinctive conceptual language typical of the subfield. The impression one gets is that psychology is a loose federation of relatively independent subfields, each with its own theoretical concerns and conceptual language, rather than a unified scientific discipline.

Textbooks that give high priority to the most up-to-date research contribute further to the sense that psychology is fragmented. Such textbooks can be useful, certainly, in providing a sort of snapshot or status report on what researchers at a particular time find most interesting. But the material cited is not necessarily of lasting significance. It is often the case that the “hot” topics of one period become passe in the next, and the patterns of changing “hotness” do not, in retrospect, always seem like progress. Textbooks that emphasize current research interests for the sake of being current can become dated quickly, and the field they describe can appear faddish.

Richard L. Shull (1995, p. 14) – Foreword II to F. S. Keller & W. N. Schoenfeld (1950) – Principles of Psychology

Psychological research

We can visit thoughts by other authors to identify additional problems in the scientific undertaking of psychology. Firstly, regarding the replication crisis and comparisons of statistical results with other fields:

This can happen in any field, but the replication crisis has unveiled a surprising resistance to the concept of replication within psychological science. (p. 529)

However, and as the second point, even had they been meaningful statistically, they were nonetheless an “apples and oranges” comparison. Psychological research very often has to contend with “proxy” measures that estimate the actual behavior of interest. Neither laboratory measures of behavior sampled under unrealistic and unnatural circumstances nor self-report surveys are a true measure of most of the behaviors that interest us. Thus, even for the best measures of behavior, there are issues related to reliability and validity. However, many medical epidemiological studies measure mortality or pathology rates that are not proxy measures; put simply, death is a perfectly reliable and valid measure of death. Thus, overzealous comparisons between psychological and medical research are fraught and potentially do more to make the field appear desperate rather than rigorous. (p. 537)

Ferguson (2015) – “Everybody Knows Psychology Is Not a Real Science”

Secondly, regarding biases in psychological research and general shakiness of the results:

As they are not only researchers, but also ordinary people, they can easily take their participants’ role and observe their own reactions to the candidate stimuli. Such an intuitive selection process will typically favor those stimuli that happen to bring about the expected phenomenon, making mental simulation an omnipresent source of bias in behavioral research.

Although commonly treated as one of psychology’s best-established phenomena, overconfidence is largely confined to studies in which judgment items were selected intuitively, presumably with a good feeling of which tricky knowledge questions will produce the desired effect.

Running many experiments using different stimuli but only reporting a single study that yields the desired result would be certainly regarded as illegitimate. However, if the same researcher runs and reports only one ‘‘main study’’ with the intended outcome, nobody would care about ‘‘pilot testing’’ used to select the stimuli that bring about that outcome.

Fiedler (2011, p. 165) – Voodoo Correlations Are Everywhere – Not Only in Neuroscience

Theology with statistics

Psychologists might find comfort in the fact that their field is not the only one that is misleadingly called a science. Yanis Varoufakis in a chapter entitled Theology with equations contests the notion of economics as a science:

Many people will tell you that your father doesn’t know what he’s talking about; that economics is a science. That just as physics uses mathematical models to describe nature, so economics uses mathematical models to reveal the workings of the economy. This is nonsense.

Economists do make use of lovely mathematical models and an army of statistical tools and data. But this does not really make them scientists, at least not in the same way that physicists are scientists. Unlike physics, in which nature is the impartial judge of all predictions, economics can never be subjected to impartial tests.

When economists insist that they too are scientists because they use mathematics, they are no different from astrologists protesting that they are just as scientific as astronomers because they also use computers and complicated charts.

But were we to confess that we are at best worldly philosophers, it is unlikely we would continue to be so handsomely rewarded by the ruling class of a market society whose legitimacy we provide by pretending to be scientists.

Yanis Varoufakis (2013, p. 118) – Talking to My Daughter About the Economy

The argument applies with full force to psychology as well. Difficult statistical models, explanatory or confirmatory factor analyses, mediational or moderational analyses, cluster analyses, multi-level modelling cannot salvage a faulty philosophy, reified concepts, poor quality data or studies without proper variable control.

So much for statistics. Now, what about the theology part? In the aptly named book What Causes Human Behavior – Stars, Selves or Contingencies? (2017) Stephen Ledoux explains:

In addition, the agential entities in the secular mysticism of psychology merely present a scaled–down version of the agential–entity power of theological mysticisms. Supposedly, for example, our culturally common heavenly maxi–god can move mountains. However, inner–agent mini gods (e.g., souls, minds, psyches, or selves) can only move body parts (e.g., arms and legs).

Stephen Ledoux (2017, p. 122) – What Causes Human Behavior – Stars, Selves or Contingencies

We can also visit a beloved idea by New Age Atheists – the Occam’s Razor. This clique would swear by following scientific principles but come human behavior, the objective monistic outlook (quite expectedly by now) breaks down. The idea is also known as the Lloyd Morgan’s Cannon – psychology violates fundamental scientific principles of parsimony:

In no case may we interpret an action as the outcome of the exercise of a higher psychical faculty, if it can be interpreted as the outcome of the exercise of one which stands lower in the psychological scale.

F. S. Keller (1958-1959, p. 31) – Supplementary Notes in F. S. Keller & W. N. Schoenfeld (1950) – Principles of Psychology

It’s cultural (isn’t everything though?)

It should be clear that psychology suffers from an inadequate philosophy, but one may look at the issue from another standpoint. Let’s not forget that scientists are also behaving organisms and the “science” done is conditioned by the wider political, ideological and social context. It won’t come as a surprise that psychological research is susceptible to private funding, wealthy interests and corporate adoption:

Yet, each of these critics and, for the most part, the majority of other critics of contemporary psychology, with few exceptions (e.g., see Gergen, 1978; Gergen & Morawski, Note 3), have failed to go beyond the threshold that their critique suggests. I believe that the step beyond has eluded them because it would demand a radical break not only with the existing tradition in psychology but also with psychology’s relation to society: This step beyond challenges some of the major value assumptions that have governed Western thought and that continue to serve particular interests and particular social arrangements and practices. (p. 733)

Furthermore, not only are these mental operations cut off from their objective roots in social and historical practice, but also, in being located within the mind of the individual, they cut off people from effective action to change their circumstances rather than their subjective understanding of these circumstances. (p. 733)

Reified cognition and reified psychological processes take what is empirically observed, abstract it from the particular sociohistorical conditions of its constitution, and grant it a timeless, objective standing. (p. 737)

Psychological reifications clothe existing social arrangements in terms of basic and inevitable characteristics of individual psychological functioning; this inadvertently authenticates the status quo, but now in a disguised psychological costume. What has been mediated by a sociohistorical process—the forms and contents of human consciousness and of individual psychological experience—is treated as though it were an “in-itself,” a reality independent of these very origins. (p. 738)

However, if psychology insistently turns its back on its reifying tendencies, it will continue uncritically to affirm existing social arrangements even while it purports simply to be discovering and describing the nature of human realities. The dual reductions of subjectivism and individualism carry the seeds of the psychological reifications that permit ideology to reign because of our ignorance of and blindness to its very presence. (p. 739)

Sampson (1981) – Cognitive Psychology as Ideology

Concluding remarks

Psychology is not a science – as was argued in this post, most of the concepts psychologists employ are hardly anything more than explanatory fictions. Transition to strict materialism in science was and always is filled with strife, bile and denial. Psychology failing to do this in the middle of the 20th century is becoming a dead-end. Even it’s contemporary philosophical ideas already belong in the faculties of history, where they will eventually end up, but due to cultural inertia and power structures likely later rather than sooner:

The manifest inability of our overspecialized scientific establishment to say anything coherent about the causes of lifestyles does not arise from any intrinsic lawlessness of lifestyle phenomena. Rather, I think it is the result of bestowing premium rewards on specialists who never threaten a fact with a theory. A proportionate relationship such as has existed for some time now between the volume of social research and the depth of social confusion can mean only one thing: the aggregate social function of all that research is to prevent people from understanding the causes of their social life.

Marvin Harris (1974, p. vii) – Cows, Pigs, Wars and Witches – The Riddles of Culture

One might very well wonder how cultural idealism, which is devoid of retrodictive or predictive principles, has been selected for and become dominant in anthropology and other social sciences. The answer may be quite simple: The majority of American social scientists are paid to prove that human behavior at both the psychological and cultural level is primarily a result of will or chance. Convinced that there are no nomothetic principles to be found, they don’t bother to look for them—and hence are never in any great danger of finding any.

This behavior—to continue to speculate—has been selected for because in our own particular form of hierarchical state society, the hungry, unemployed, and otherwise frustrated and unfulfilled majority are expected to blame their losses on wrong attitudes, bad values, weak wills, and lousy luck, rather than on the Alice-in-Wonderland design of the sociocultural system which governs their lives.
