Automaticity and Free Will

Lecture Supplement

In its early days, cognitive social psychology tacitly focused on deliberate, conscious thought, as represented by such topics as impression formation (person perception), attribution theory, person memory, impression management (strategic self-presentation), and social exchange.  

"The Automaticity of Everyday Life"

For example, John Bargh (1984) famously argued that

As Skinner argued so pointedly, the more we know about the situational causes of psychological phenomena, the less need we have for postulating internal conscious mediating processes to explain these phenomena.

In Bargh's view, most social behavior is preattentive and automatic in nature.  It occurs in response to an environmental trigger, in a manner analogous to priming, independent of the person's conscious intentions, beliefs, attitudes, and choices, and also independent of the person's deployment of attention.  To the extent that responses to social stimuli are mediated by internal mental representations, these internal mental representations of the situation are constructed automatically, and then "dumped" in consciousness.

Automaticity in Impression-Formation

To illustrate Bargh's position, consider an experiment by Bargh and Pietromonaco (1982), which was presented to subjects as a simple target-detection task.  The subjects were simply asked to attend to a computer screen, and press a key whenever a particular target appeared.  What they were not told was that a series of words would be presented in the periphery of their vision, or parafoveally.  The words were a mix: some of them were related to hostility, while others were neutral.  Actually, one group got 0% hostile primes, another 20%, and another 80%.  Presentation of each word was followed by a pattern mask that rendered it inaccessible to conscious perception (we'll discuss masking in the lectures on "The Explicit and the Implicit").  The purpose of the parafoveal presentation was to insure that the words were not processed consciously, because they were not the focus of conscious attention.  Accordingly, a later recognition test confirmed that the subjects did not remember many of the words.

All of this was a set-up, of course, for the main experiment, in which subjects were asked to perform an impression-formation task.  They read a story about a fictional character, Donald, who is depicted as engaging in a number of ambiguous behaviors, many of which could be interpreted as hostile.  Then they were asked to rate Donald's personality on a series of trait adjectives.  The trait ratings were then coded for negativity in general, and for hostility in particular.  The subjects in the 0% condition tended to rate Donald as generally negative, but not particularly hostile.  But in the 20% condition, and especially in the 80% condition, they rated Donald as hostile as well as just generally unpleasant.

Bargh's interpretation of this study is that the subjects perceived the hostile trait adjectives preconsciously, and that this preconscious processing automatically activated a negative, hostile schema which then guided the interpretation of Donald's ambiguous behaviors. 

Automaticity in Social Behavior

In a later experiment by Bargh et al. (1996), subjects performed a "scrambled sentences" task in which they were given a jumble of words and asked to arrange them into complete sentences. 

At the end of the experiment, the subjects emerged from the lab room to find the experimenter engaged in a conversation with another person, who was actually an experimental confederate.  The conversation continued for up to 10 minutes, all the while the experimenter assiduously ignored the waiting subject.  The main result was that subjects in the Rude condition were more likely to interrupt the experimenter than were subjects in the Polite condition, with subjects in the Neutral condition falling somewhere in between.

Bargh's interpretation of this experiment is that reading "rude" words automatically primed the subjects to interpret the experimenter's behavior as rude, and thus more likely to behave rudely in turn, interrupting his conversation.  

In his analysis of social behavior, Bargh advocates social ignition over social cognition.  In his view, automaticity pervades everyday live, and conscious awareness is largely an after-the-fact rationalization of what we have thought and done.  In his view, the earlier (if tacit) emphasis on consciousness in social behavior is a holdover from an earlier embrace of serial processing in models of attention and cognition.  But now, he asserts, cognitive psychology emphasizes parallel processing -- as in McClelland and Rumelhart's connectionist "parallel distributed processing" models of cognition.  Bargh is a cognitive social psychologist, but he no longer equates cognition with consciousness:

The Automaticity Juggernaut

Bargh is not alone in this project.  Bargh is a leader of the automaticity movement within cognitive psychology, but he has a large number of compatriots and followers, who together comprise a "school" of psychology that I have called The Automaticity Juggernaut.

Denise Park, serving as guest editor of a special issue of American Psychologist -- the official journal of the American Psychological Association, and read by almost every experimental and clinical psychologist in the country, if not the world -- wrote an introductory editorial entitled "Behavior -- It's Involuntary", in which she announced the discovery of automaticity as a "fundamental breakthrough" in our understanding of motivation and free will.

Timothy Wilson, at the University of Virginia, has long argued that we have limited introspective awareness of our own attitudes and other causes of behavior, because attitudes are largely unconscious.  

Sandra Blakeslee, one of the best science writers in the business, specializing in psychology, wrote an article for the New York Times Magazine claiming that we humans "are closer to zombies than sentient beings most of the time".

Malcolm Gladwell, another best-selling science writer specializing in the social sciences wrote a book, Blink (2005), surveying the evidence for "the new unconscious" and "The Power of Thinking Without Thinking".

Ap Dijksterhuis, a Dutch psychologist, has promoted an posed that unconscious thought is actually superior than conscious thought when making complex choices.

Daniel Wegner, a psychologist at Harvard, has provocatively proposed that conscious will is an illusion, and plays no causal role in either thought or behavior.  

 Just so he won't be misunderstood, Wegner presents a diagram of the relations between conscious and unconscious thought and action.

Given that The Illusion of Conscious Will was perceived by many as an attack on free will, it's not at all clear that there was any misinterpretation.  See Wegner's own "Precis of The Illusion of Conscious Will" in Behavioral & Brain Sciences, 2004, 27, 649-692.

Assertion and Evidence

It's an interesting argument, that our behavior is so powerfully determined by automatic processes that we have greatly limited conscious awareness and control over our attitudes, beliefs, and the behavior they (apparently) cause.  If it were true, then this post-Freudian "naturalization" of human experience, thought, and action would indeed be a cause for sorrow, because it would deprive us of the core of what, for thousands of years (at least, in Western culture, since the Genesis story of Adam and Eve) we have considered human nature -- our ability to know what we are doing, and freely choose one path over another.  

But is it really true?  

Not necessarily.

Note, first of all, that the sorts of experiments performed by Bargh and his colleagues are only demonstration experiments.  That is, they show that unconscious, automatic processes play some role in behavior.  But that should come as no surprise.  Psychologists have long understood that some mental processes are automatic and others are controlled; or, alternately, that every mental task involves some mix of automatic and controlled processes.  

But the automaticity juggernaut involves a much more dramatic claim: that automaticity so dominates experience, thought, and action that consciousness plays little or no role in the ordinary course of everyday living.  To uphold that claim, we need a certain kind of experiment, one that actually compares the strength of automatic and controlled processes against each other.

Process Dissociation Redux

Which is where Jacoby's process-dissociation procedure (PDP) comes in.  Although still somewhat controversial, the PDP remains the most widely used means of estimating the relative contributions of automatic and controlled processes in task performance.  Although widely used in cognitive psychology, the PDP has been rarely used in social psychology.  But when it has been used, the results have been revealing -- and reassuring.

Among the earliest applications of the PDP concerned the false fame effect.  Jacoby and his colleagues (1989) asked subjects to study a list of non-famous names, such as Sebastian Weisdorf, followed by a memory test.  One day later, they were given a long list of names, some clearly famous and others not, and asked simply to judge which of them was the name of a famous person.  Among the non-famous names on the list were names from the list that had been memorized 24 hours earlier.  The chief finding of the experiment was that the previously studied non-famous names were now judged to be famous.  Jacoby argued, reasonably, that the initial study session primed the non-famous names, so that when they appeared on the later fame-judgment task they "rang a bell", and that this increased familiarity was interpreted as evidence of fame.  And, of course, the priming was interpreted as automatic in nature.

But was it?  In a later study, Jennings and Jacoby (1993) applied the PDP to the false fame effect.  The experiment was run as before, except that this time there was both an Inclusion and an Exclusion task (we won't get bogged down in the details of how the Method of Opposition was actually implemented).  Moreover, the entire study was run under three experimental conditions: first, they compared full attention (no distraction) to divided attention (where the subjects performed a distracting task while they made fame judgments, in order to restrict cognitive resources; second, they repeated the full-attention condition with a group of elderly subjects, to compare with the college students.  

The results were revealing.  In the full-attention condition, which was comparable to the original demonstration of the false fame effect, controlled processing was more influential than unconscious, automatic processing.  The role of conscious, controlled processing was diminished in the divided-attention condition (naturally, because of the more limited cognitive resources available), and among the elderly (because of age-related declines in cognitive capacity).  But even under these conditions, automatic processing did not dominate conscious processing.  It would be more accurate to say simply that the false fame effect was produced by a mix of conscious and unconscious processing.

Similar findings were obtained in an experiment on spontaneous trait inferences.  Uleman and his colleagues have performed a number of experiments where subjects studied the photographs of strangers, each of which was paired with a simple behavioral description, such as Jane gave a dollar to the beggar).  Two days later, they were presented with a larger set of set of photos, including some of the photos studied previously, and asked to make judgments about the personalities of the people depicted.  The finding was that targets depicted in the old photos tended to receive trait attributions in line with the behavioral descriptions that had accompanied the photos studied on the first day.  For example, subjects tended to describe "Jane" as kind.  The interpretation was that, in line with what is called the fundamental attribution error, subjects automatically attribute behavior to a person's personality traits and other internal characteristics, rather than to the situation or some other external factor.  So, presentation of the behaviors automatically primed traits, which were then attached to the people depicted in the photos.  When the same photo appeared the next day, the subject automatically retrieved the corresponding trait information from memory.

But did it?  to his credit, Uleman and his colleagues (2005) applied the PDP to their experimental paradigm, running subjects under both Inclusion and Exclusion instructions.  In one condition, the subjects made trait judgments immediately after studying the photographs; in other conditions, the trait judgments were delayed by 20 minutes, or 2 days (as in the initial experiment).  In the "immediate" condition, in fact, conscious processing proved to be more influential than automatic processing.  The role of conscious processing was reduced after a 20-minute or 2-day delay, reflecting the time-related decline of conscious recollection.  But even in these conditions, task performance was mediated by a pretty even mix of conscious and unconscious processing.

Perhaps the most revealing of these PDP studies is a pair of experiments by Payne and his colleagues concerning the weapon bias.  In these experiments, subjects are shown a brief video clip, and they have to judge whether the person in the clip is holding a weapon (a knife or a gun, for example) or a tool (like a wrench or a TV remote).  Before performing this task, however, the (white) subjects are shown the face of a black or white person.  The finding is that the white subjects are more likely to misidentify tools as guns when they have been primed by a black face.  Moreover, they were faster to correctly identify the object as a gun after they had been primed with a black face, and faster to correctly identify the object as a tool after they had been primed with a white face.  The interpretation is that the presentation of the faces automatically primed racial stereotypes in these white college students, including the stereotypical association of black people with crime and violence; and that this stereotype automatically biased their weapon judgments.  But did it?  It depends.

In his initial experiment, Payne (2001) applied the MOP in his standard experimental paradigm, in which there was no deadline, and subjects could take their time making their judgments.  In this case, controlled, conscious processing proved to be more important than automatic processing.

In a later study, Payne and his colleagues imposed a deadline on the subjects, forcing them to make their decision, weapon or tool, within 500 msec of the video.  This was done to more closely simulate the situation of a police officer who must make a split-second decision about whether an object in a suspect's hand is a weapon.  Under these circumstances, where subjects had to make very rapid decisions, automatic processes dominated; but there was still a healthy amount of controlled processing in the mix.

So, the bottom line is that automaticity plays some role in social cognition and behavior, as we would expect -- because automaticity plays some role in everything we do.  The relative impact of automaticity is increased under conditions that militate against conscious processing, such as distraction (which consumes attentional resources), long retention intervals (which induce forgetting) or short response windows (which preclude conscious processes from coming into play).   And even under ordinary circumstances, there is enough "mindlessness" in the ordinary course of everyday living to convince us that there's something to this automaticity business. 

But the assertion that "humans are closer to zombies than sentient beings much of the time" (Blakeslee, 2002) is wide of the mark.  There's just no evidence to support any such belief.

The Libet Experiment

One of the most provocative findings motivating the automaticity juggernaut was reported by Benjamin Libet (1983), a physiologist at UC San Francisco, on the readiness potential, a form of the event-related potential (ERP) recorded in the EEG.  In fact, the Libet experiment inspired Wegner's argument that conscious will is an illusion, and that the "actual causal path" goes directly from an unconscious cause of action to the action itself, bypassing conscious thought.

Normally, the ERP is measured in response to a stimulus.  When averaged over many trials, the EEG produces a series of waves occurring within about 1000 msec of the presentation of the stimulus. 

In a variant on the basic RP experiment, Libet and his colleagues (1983) asked subjects to watch a special clock, whose hands moved full circle very quickly, once every 2.56 seconds.  Every time they moved their finger, they were to use the clock to record the precise moment when they decided to initiate the movement.  As you can imagine, this isn't easy, but subjects can learn to do it with practice.

Looking backward at the EEG, Libet observed the RP shift begin before subjects were aware of their conscious intention to move their fingers.  So, Libet argued, there were two components to the timing of voluntary, spontaneous acts:

Libet had earlier obtained evidence, again from ERP data, that a stimulus must persist for approximately 500 msec in order to be conscious.  Otherwise, it remains conscious.

Putting the two findings together, Libet (1983, 1985, 2002, 2005) proposed a "time on" theory of consciousness.

And, needless to say, the Libet experiment was highly controversial -- precisely because it seemed to undermine our common experience that we have free will.  And pretty soon, criticisms of the Libet experiment began to pile up.  The first important point was that people were able to replicate Libet's  own findings in their own laboratories (e.g., Banks & Pockett, 2007).  

But as they tried to replicate Libet's findings, they began to understand the difficulties with his experimental procedure. 

Moreover, some commentators cast doubts on the ecological validity of Libet's procedure -- that is, whether the results from his laboratory experiment were generalizable to the real world.

When Miller et al. did what Libet did, they got what Libet got: a "predecisional negative shift" in the EEG -- in other words, the Type II RP.  But when the subjects in the control group made their movements without watching the clock, there was no such shift: the EEG was essentially flat until just before they actually made their movement.  So, it appears that the predecisional negative shift was an artifact of the attention paid to the clock -- the cognitive effort involved in watching the clock and recording decision time.  It does not, after all, indicate the unconscious initiation of ostensibly "voluntary" behavior, as Libet thought it did. 

Unfortunately, Libet died in 2007, so he cannot respond to this new criticism, as he faithfully responded to all the others that accrued from his initial report in 1983 up until his death in 2007. 

Which is too bad, in a way, because recently Andrew Papanicolau, has published a comprehensive overview of conceptual and empirical critiques of the Libet Experiment, and of other, more recent neuroscientific demonstrations, themselves mostly take-offs on the Libet Experiment, that free will doesn't exist (Consciousness & Cognition, 2017).  Papanicolau points out that the relevant research does not unequivocally undermine the concept of free will.  Partly this is because the research itself has yielded contradictory findings.  But it's also because the extant studies share "two fundamental shortcomings":

The Automaticity Juggernaut -- 

Or, Are We All Zombies After All?

A related reason can be found in the physics envy that infects many psychologists -- the desire to make psychology a "hard science", like physics, instead of the blend of biological and social science that it actually is.  

Interestingly physics envy was original diagnosed in biology, by Joel Cohen (Science, vol. 172, May 14, 1971).  And more recently it has been diagnosed in economics by Andrew Lo, in a draft paper posted to the Internet in 2010.  Given that psychology is both a biological and a social science, it's no wonder that psychologists suffer from it -- we get it from both directions!

Given the assumption that all we have is the physical world, which is all we appear to have, at least so far as science is concerned, is hard to understand how free will could enter in the closed causal sequence that characterizes the physical world.  Automaticity -- in which an environmental stimulus automatically triggers a process that automatically generates a mental state that automatically determines behavior -- is a way to come close to the probabilistic pinball determinism of modern physics, if not the clockwork determinism of the classical Newtonian version.

The distinction between clockwork and pinball determinism comes from The Cosmic Code: Quantum Physics as the Language of Nature by Heinz Pagels (1982).  

But why is it social psychologists, like Bargh, and Wilson, and Wegner, who are so avid in promoting automaticity -- social scientists, not neuroscientists, who ought to understand the complexity of human behavior and the role of consciousness in it?  The answer to that question, I fear, comes from an unholy alliance between traditional social psychology and behaviorism.  Social psychology was traditionally defined, as by Gordon Allport (1954), as the study of social influence -- its subject matter was taken to be the role of the social situation in determining the individual's experience, thought, and action.  That is a position that is perilously close to that of Watsonian and Skinnerian behaviorism, which emphasized the association between environmental stimulus and organismal response, with no mental processing inbetween.  It is no accident, I think, that Bargh cites Skinner favorably in some of his most prominent articles.  

Proponents of automaticity like Bargh do not consider behavior to be caused by the objectively described situation, as Skinner would have had it.  Rather, like all cognitive social psychologists, they place emphasis on the person's internal mental representation of the situation, and the cognitive processes by which it is constructed.  While it is axiomatic in cognitive social psychology that behavior is a function of the perceived situation, as opposed to the situation as objectively described, Bargh and his confreres argue that the mental representation of the situation is itself constructed automatically and preconsciously. Thus, Bargh and other automaticity theorists are able to maintain a superficial allegiance to cognitivism, while at the same time harkening back to the radical situationism of Skinner, and of earlier, pre-cognitive social psychology, and embracing the conscious inessentialism implicit in the work of Dennett. 

With apologies to Alexander Dubcek (1968), and Susan Sontag (1982) I call this

 behaviorism with a cognitive face.

One has to wonder: We had a cognitive revolution for this -- to be told that Skinner had it right after all?

Reading the social-psychological literature on automaticity, one might almost wonder why we bothered to have a cognitive revolution in the first place.

To bring this discussion full circle: To some extent, the "automaticity juggernaut" within contemporary social psychology exemplifies the ambivalence with which the idea of consciousness is held in cognitive psychology and cognitive science (as in Flanagan's conscious shyness).  In addition, it seems to reflect a sincere belief, on the part of some social psychologists (including Bargh himself), that a truly scientific explanation of behavior must be deterministic, and leaves no room for anything like conscious will.
