hard decisions shape the neural coding of preferences

https://doi.org/10.1523/jneurosci.1681-18.2018
people often must decide between two items of equal value. Previous studies have suggested people update their preferences after the fact in order to feel more confident in their decision.
Stefan Bode, Katharina Voigt, and colleagues tested an alternative hypothesis: difficult decisions actively shape one's preferences. The researchers found when faced with a choice between two desirable snack foods, participants activated a brain network that assigns values to different options during the decision-making process. This neural activity -- in addition to which snack participants' eyes focused on -- predicted how they would later reevaluate the items, valuing the chosen snack more than the unchosen one. These findings challenge traditional views of the relationship between decisions and preferences.
abstract Hard decisions between equally valued alternatives can result in preference changes, meaning that subsequent valuations for chosen items increase and decrease for rejected items. Previous research suggests that this phenomenon is a consequence of cognitive dissonance reduction after the decision, induced by the mismatch between initial preferences and decision outcomes. In contrast, this functional magnetic resonance imaging and eye-tracking study with male and female human participants found that preferences are already updated online during the process of decision making. Preference changes were predicted from activity in left dorsolateral prefrontal cortex and precuneus while making hard decisions. Fixation durations during this phase predicted both choice outcomes and subsequent preference changes. These preference adjustments became behaviourally relevant only for choices that were remembered and were in turn associated with hippocampus activity. Our suggest that preferences evolve dynamically as decisions arise, potentially as a mechanism to prevent stalemate situations in underdetermined decision scenarios.

breathing is coupled with voluntary action and the cortical readiness potential
hyeong-dong park et al. 2020
http://dx.doi.org/10.1038/s41467-019-13967-9
voluntary action is indeed linked to your body’s inner state, especially with breathing and expiration but not with some other bodily signals, such as the heartbeat,” explains Olaf Blanke, EPFL’s Foundation Bertarelli Chair in Cognitive Neuroprosthetics and senior author.
At the center of these results is the readiness potential (RP), a signal of brain activity observed in the human cortex that appears not only before voluntary muscle movement, but also before one becomes aware of the intention to move. The RP is the signature of voluntary action since it consistently appears in brain activity measurements right before acts of free will (like being aware that one wants to reach for the chocolate).
Interpretations of the RP have been debated for decades. Some interpret the RP to show that free will is an illusion, since the RP precedes the conscious experience of free will. It seems to show that the brain commits to a decision (chocolate) before we are even consciously aware of having made that decision.
More recently, it was suggested that the RP could be an artefact of measurement, potentially putting free will back into our command.
But if we take on the view that our conscious decisions arise from a cascade of firing neurons, then the origin of the RP may actually provide insight into the mechanisms that lead to voluntary action and free will. The way the brain’s neurons work together to come to a decision is still poorly understood. Our conscious experience of free will, our ability to make decisions freely, may then be intricately wired to the rest of our body.
The EPFL results suggest that the origin of the RP is linked to breathing, providing a new perspective on experiences of free will: the regular cycle of breathing is part of the mechanism that leads to conscious decision-making and acts of free will. Moreover, we are more likely to initiate voluntary movements as we exhale. (Did you reach for that piece of chocolate during an exhale?)
These findings suggest that the breathing pattern may be used to predict ‘when’ people begin voluntary action. Your breathing patterns could also be used to predict consumer behavior, like when you click on that button. Medical devices that use brain-computer interfaces could be tuned and improved according to breathing. The breathing-action coupling could be used in research and diagnostic tools for patients with deficits in voluntary action control, like obsessive compulsive disorders, Parkinson disease, and Tourette syndromes. Blanke and Hyeong-Dong Park, first author of this research, have filed a patent based on these findings.
Free will hijacked by interoceptive signals?
More generally, the EPFL findings suggest that acts of free will are affected by signals from other systems of the body. Succumbing to that urge to eat chocolate may depend more on your body’s internal signals than you may realize!
Blanke elaborates, “That voluntary action, an internally or self-generated action, is coupled with an interoceptive signal, breathing, may be just one example of how acts of free will are hostage to a host of inner body states and the brain’s processing of these internal signals. Interestingly, such signals have also been shown to be of relevance for self-consciousness.”
You may be tempted to blame acts of chocolate binging on interoceptive electrical signals hijacking your free will. The gut-mind connection is an active field of research and interoceptive messages sent to the brain certainly impact food cravings. For now, this latest EPFL research only improves predictions of when you will indulge in that craving, and not what you actually crave.
Acts of free will and inner states of the body
The prevailing view in neuroscience is that consciousness is an emergent phenomenon of the brain. Firing of the brain’s neurons leads to consciousness and the feeling of free will or voluntary action. By belonging to the physical universe, the brain’s electrical activity within the constraints of anatomy, is subject to the laws of physics. In this sense, brain signals encoding the body, lungs and heart might naturally affect the brain’s cognitive states too and therefore influence acts of free will.
To test whether the RP depends on the body’s inner state and the brain’s representation thereof, Blanke and colleagues asked 52 subjects to press a button at will at Campus Biotech in Geneva. EEGs monitored brain activity, a belt around the chest measured breathing activity and cardiac activity was recorded.
The scientists found that the RP and voluntary action (pressing the button) is linked to the body’s inner state — the regular breathing cycle — but not to the heartbeat. Participants initiated voluntary movements more frequently during an exhale than an inhale and were completely unaware of this breathing-action coupling. The RP was also modulated depending on the breathing cycle.
EPFL scientist and first author of the study Hyeong-Dong Park explains, “The RP no longer corresponds only to cortical activity ‘unconsciously preparing’ voluntary action. The RP, at least partly, reflects respiration-related cortical processing that is coupled to voluntary action. More generally, it further suggests that higher-level motor control, such as voluntary action, is shaped or affected by the involuntary and cyclic motor act of our internal body organs, in particular the lungs. Still the precise neural activity that controls breathing remains to be mapped.”
The readiness potential and interpretations
Philosophers, psychologists, and more recently neuroscientists have long debated our ability to act freely. The meaning of the readiness potential (RP) has been questioned ever since its discovery by neuroscientists Hans Helmut Kornhuber and Lüder Deecke in 1965, and later regarding its relation to free will in neuroscientist Benjamin Libet’s experiments.
The entire brain consists of approximately 100 billion neurons, and each individual neuron transmits electrical signals as the brain works. Electrodes placed on the head can measure the collective electrical activity of the brain’s neurons, seen as wavy lines called an electroencephalogram (EEG).
In 1965, neuroscientists Hans Helmut Kornhuber and Lüder Deecke conducted a seminal experiment to test voluntary action and discovered a recurring pattern of brain activity. They placed EEG electrodes on top of the subject’s head, and asked the subject to press a button at will. Kornhuber and Deecke discovered that the EEG consistently exhibited a rising slope of wavy lines, the readiness potential, 1 second or more before voluntary movement.
In the early 1980s, neuroscientist Benjamin Libet further tested the relationship between the RP and conscious awareness or intention of voluntary action. His highly influential results showed that approximately 200ms before his subjects pressed the button, they were aware of an urge or the intention to act, something Libet referred to as the W time, and yet the RP consistently preceded W time.
Libet suggested that these findings showed that even before we make a conscious decision of voluntary action, the brain was already unconsciously activated and involved in planning the action.
Some have interpreted the relation between the RP and W time as an indication that human free will might be an illusion. The RP is viewed as the brain committing to a decision (to press the button) before the subject is even aware of having made that decision. If commitment to a decision is being made before we are even aware of it, then what mechanism is making the decision for us?
For the neuroscientist who considers consciousness to arise from brain activity (versus brain activity arising from consciousness), Libet’s results may not surprising, since the conscious experience of free will is viewed as an emergent phenomenon of brain activity.
Yet, Libet’s results are in conflict with the notion of free will and voluntary action in philosophy of the mind, in folk psychology, in culture, and in legal matters.
abstract Voluntary action is a fundamental element of self-consciousness. The readiness potential (RP), a slow drift of neural activity preceding self-initiated movement, has been suggested to reflect neural processes underlying the preparation of voluntary action; yet more than fifty years after its introduction, interpretation of the RP remains controversial. Based on previous research showing that internal bodily signals affect sensory processing and ongoing neural activity, we here investigated the potential role of interoceptive signals in voluntary action and the RP. We report that (1) participants initiate voluntary actions more frequently during expiration, (2) this respiration-action coupling is absent during externally triggered actions, and (3) the RP amplitude is modulated depending on the respiratory phase. Our findings demonstrate that voluntary action is coupled with the respiratory system and further suggest that the RP is associated with fluctuations of ongoing neural activity that are driven by the involuntary and cyclic motor act of breathing.

when not choosing leads to not liking: choice-induced preference in infancy
alex m. silver et al. 2020
doi.org/10.1177%2f0956797620954491
When a baby reaches for one stuffed animal in a room filled with others just like it, that seemingly random choice is very bad news for those unpicked toys: the baby has likely just decided she doesn't like what she didn't choose.
Though researchers have long known that adults build unconscious biases over a lifetime of making choices between things that are essentially the same, the new Johns Hopkins University finding that even babies engage in this phenomenon demonstrates that this way of justifying choice is intuitive and somehow fundamental to the human experience.
"The act of making a choice changes how we feel about our options," said co-author Alex Silver, a former Johns Hopkins undergraduate who's now a graduate student in cognitive psychology at the University of Pittsburgh. "Even infants who are really just at the start of making choices for themselves have this bias."
The findings are published today in the journal Psychological Science.
People assume they choose things that they like. But research suggests that's sometimes backwards: We like things because we choose them. And, we dislike things that we don't choose.
"I chose this, so I must like it. I didn't choose this other thing, so it must not be so good. Adults make these inferences unconsciously," said co-author Lisa Feigenson, a Johns Hopkins cognitive scientist specializing in child development. "We justify our choice after the fact."
This makes sense for adults in a consumer culture who must make arbitrary choices every day, between everything from toothpaste brands to makes of cars to styles of jeans. The question, for Feigenson and Silver, was when exactly people start doing this. So they turned to babies, who don't get many choices so, as Feigenson puts it, are "a perfect window into the origin of this tendency."
The team brought 10- to 20-month-old babies into the lab and gave them a choice of objects to play with: two equally bright and colorful soft blocks.
They set each block far apart, so the babies had to crawl to one or the other -- a random choice.
After the baby chose one of the toys, the researchers took it away and came back with a new option. The babies could then pick from the toy they didn't play with the first time, or a brand new toy.
"The babies reliably chose to play with the new object rather than the one they had previously not chosen, as if they were saying, 'Hmm, I didn't choose that object last time, I guess I didn't like it very much,' " Feigenson said. "That is the core phenomenon. Adults will like less the thing they didn't choose, even if they had no real preference in the first place. And babies, just the same, dis-prefer the unchosen object."
In follow-up experiments, when the researchers instead chose which toy the baby would play with, the phenomenon disappeared entirely. If you take the element of choice away, Feigenson said, the phenomenon goes away.
"They are really not choosing based on novelty or intrinsic preference," Silver said. "I think it's really surprising. We wouldn't expect infants to be making such methodical choices."
abstract The question of how people’s preferences are shaped by their choices has generated decades of research. In a classic example, work on cognitive dissonance has found that observers who must choose between two equally attractive options subsequently avoid the unchosen option, suggesting that not choosing the item led them to like it less. However, almost all of the research on such choice-induced preference focuses on adults, leaving open the question of how much experience is necessary for its emergence. Here, we examined the developmental roots of this phenomenon in preverbal infants (N = 189). In a series of seven experiments using a free-choice paradigm, we found that infants experienced choice-induced preference change similar to adults’. Infants’ choice patterns reflected genuine preference change and not attraction to novelty or inherent attitudes toward the options. Hence, choice shapes preferences—even without extensive experience making decisions and without a well-developed self-concept.

A blue wind is now knocking at the door to your heart, yet
You are merely gazing and smiling at me
Something gently touching - you’re so intent on seeking it out
That you can’t even see your fate yet, with such innocent eyes
But someday I think you’ll find out that what’s on your back
Are wings that are for heading for the far-off future
The cruel angel’s thesis will soon take flight through the window
with surging, hot pathos, if you betray your memories
Embracing this sky and shining, boy, become legend!
Sleeping for a long time in the cradle of my love
The morning is coming when you alone will be called by a messenger of dreams
Moonlight reflects off the nape of your slender neck
Stopping time all throughout the world I want to confine them, but...
So if two people being brought together by fate has any meaning,
I think that it is a bible for learning freedom
The cruel angel’s thesis, the sorrow then begins
You held tight to the form of life when you woke up from that dream
You shine brighter than anyone else. Boy, become legend!
People create history while weaving love
Even knowing I’ll never be a goddess or anything like that, I live on
The cruel angel’s thesis will soon take flight through the window
with surging, hot pathos, if you betray your memories
Embracing this sky and shining, boy, become legend!
exploring why leaders do what they do: an integrative review of the situation-trait approach and situation-encoding schemas
ryan k. gottfredson, christopher s. reina 2020
http://dx.doi.org/10.1016/j.leaqua.2019.101373
“Mindsets are leaders’ mental lenses that selectively organize and process information in unique ways, guiding them toward corresponding actions and responses,” Reina said. “In other words, mindsets dictate what information leaders take in and use to make sense of and navigate the situations they encounter. Simply, mindsets drive why and what leaders do.”
The authors identified four distinct series of mindsets that affect leaders’ ability to engage, navigate change and lead more effectively: growth vs. fixed mindsets, learning vs. performance mindsets, deliberative vs. implemental mindsets, and promotion vs. prevention mindsets.
“If organizations want their investment in leadership development to more fully pay off, it is essential that they prioritize mindset development, specifically by targeting growth, learning, deliberative and promotion leader mindsets,” Reina said. “If organizations focus on and help leaders hone these mindsets, they are much more likely to give their leaders and their organization the gift of lasting and meaningful development.”
A growth mindset is the belief that people, including oneself, can change their talents, abilities and intelligence, while those with a fixed mindset do not believe that people can change.
A learning mindset involves being motivated toward increasing one’s competence and mastering something new. A performance mindset involves being motivated toward gaining favorable judgments — or avoiding negative judgments — about one’s competence.
Leaders with a deliberative mindset have a heightened receptiveness to all kinds of information as a way to ensure that they think and act optimally. Leaders with an implemental mindset are more focused on implementing decisions, which closes them off to new and different ideas and information.
Those with a promotion mindset focus on winning and gains. They identify a specific purpose, goal or destination and prioritize making progress toward it. Conversely, leaders with a prevention mindset focus on avoiding losses and preventing problems at all costs.
abstract In order to enhance leaders’ effectiveness, it is critical to clearly and accurately understand the underlying processes that contribute to leaders’ decision making and behavior. The traditional trait approach to understanding leaders’ underlying processing carries limitations and does not capture any of the situational characteristics that may be important. We thus advance the situation-trait approach by introducing the Cognitive Affective Processing Systems framework more fully into the leadership domain. A primary benefit of integrating this framework is that it identifies an attribute largely overlooked by leadership scholars, yet foundational to leaders’ processing and behaviors: situation-encoding schemas. We integrate and review decades of research on four sets of situation-encoding schemas to demonstrate their important role in determining why leaders do what they do. This consensus shift, novel focus on situation-encoding schemas, and integration of four disparate sets of well-studied situation-encoding schemas has important implications for leaders’ self-awareness, meta-cognition, effectiveness, and development.
