#cognitive evolution

For generations, we have told ourselves a simple and reassuring story about our own origins. It was a story of a linear march of progress, with our species, Homo sapiens, standing alone at the pinnacle of ingenuity and intelligence. We were the toolmakers, the innovators, the ones who possessed the unique spark of complex thought that allowed us to dominate the planet. But the earth sometimes…

Culture, as well as other cognitively-demanding attributes we prescribe uniquely to humans, may not be so unique. Perhaps part of the reason why animal culture remains controversial is because animals are subject to much stricter standards of assessment than humans

Imitation, which is yet to be unequivocally proven among animals may not exists among humans in the definition of being a topographic match of motor actions. Rather, human perceive the more general intent behind the actions of the demonstrator, and use it to direct their own movement.

Endocannabinoids are found in all areas mediating food intake and appetite  mood, concentration and other areas reflected in the behaviour exhibited by people under the influence of marijuana. After being starved for a number of days, the levels of endocannabinoids are increased in the body, influencing how much we like food. Endoopioids are responsible for us wanting the food. The wanting is what is involved in the DOPA signalling pathway, and why satisfaction of the wants leads to addiction (why opium and derivatives is addictive). 

In today's dose of "Research Which Seems to Have Proven the Already Blatantly Obvious" we get to wonder whether said conclusions are, in fact, Painfully Self-Evident or only made to appear so when Contorted to Fit with Psuedo-Narrative Journalistic Conventions.

Philosophers have long debated the foundations of moral decision-making. “Rationalists” from Socrates to Immanuel Kant argued that people should rely on intellect when distinguishing right from wrong. “Sentimentalists” like David Hume believed the opposite: emotions such as empathy should guide moral decisions.

Now Hazel associate professor of the social sciences Joshua Greene, a philosopher, experimental psychologist, and neuroscientist, is trying to resolve this dispute by combining brain-scanning technology with classic experiments from moral psychology to provide a new look at how rationality and emotion influence moral choices. His work has led him to conclude that “emotion and reason both play critical roles in moral judgment and that their respective influences have been widely misunderstood.”

Greene’s “dual-process theory” of moral decision-making posits that rationality and emotion are recruited according to the circumstances, with each offering its own advantages and disadvantages. He likens the moral brain to a camera that comes with manufactured presets, such as “portrait” or “landscape,” along with a manual mode that requires photographers to make adjustments on their own. Emotional responses, which are influenced by humans’ biological makeup and social experiences, are like the presets: fast and efficient, but also mindless and inflexible. Rationality is like manual mode: adaptable to all kinds of unique scenarios, but time-consuming and cumbersome.

“The nice thing about the overall design of the camera is that it gives you the best of both worlds: efficiency in point-and-shoot mechanisms and flexibility in manual mode,” Greene explains. “The trick is to know when to point and shoot and when to use manual mode. I think that this basic design is really the design of the human brain.”

Only after we've Related the Issue to Closest Approximate Homily (as, obviously, No One Would Care Otherwise) and Shoe-horned it Into An Analogy (although, doesn't seem to entirely be the journalist's fault in this case, and the researcher had his analogy camera-ready (hah!) and phrased in sound-byte) - only then can we even begin to discuss what was, you know, actually looked at and done in what, until this point, we could only assume was a scientific study.

His primary tool is functional magnetic resonance imaging (fMRI), which takes advantage of the fact that many mental functions are localized to specific areas of the brain. Deliberative reasoning, for instance, is housed in the prefrontal cortex, whereas the amygdala is considered the seat of the emotions. By monitoring blood flow to these areas, fMRI allows Greene and his colleagues to observe exactly when someone is relying on “manual mode” or “automatic settings.”

For one experiment (published in Neuron in 2004), Greene asked his subjects how they would respond to a moral dilemma known as “the trolley problem,” which involves pushing an innocent stranger in front of a speeding trolley in order to save five other strangers from being killed. Despite the utilitarian value of killing a single stranger, most respondents said that doing so would be morally wrong: the thought of pushing an innocent person to his death was too much. Yet a handful of subjects said they would end the stranger’s life in order to rescue the others, and Greene found that this group exhibited increased activity in the dorsolateral prefrontal cortex, a brain region he calls “the heart of manual [i.e., rational] mode.”

But - wait for it - here it comes - The Maybe Not Just So, or The It's Complicated Moment.

Make a claim, build a model - then explain why that was a gross oversimplification or how it may have been based in inaccurate assumptions.

It's the conflict in the narrative. It's the moment of tension. The crisis. (Because we'd totally be getting bored by this point, otherwise. Obviously. It's what keeps this from being a boring textbook explaining thing.)

More recently, though, Greene’s research has led to a slight alteration in his camera analogy. In a series of experiments published in Neuron in 2010, he used fMRI to further explore the interface between rationality and emotion. Again he scanned the brains of subjects responding to the trolley problem, but this time he repeatedly altered the number of lives at stake and the likelihood that the victims could be saved. With 40 lives on the line and a 95 percent chance of their deaths without intervention, for example, nearly every test subject was willing to sacrifice one life to save the rest. But with 15 people at risk and a 50-50 chance for their survival, Greene reports, “[R]espondents were split down the middle as to whether they would intervene.”

As his subjects considered these variations, they all showed increased activity in brain areas that assign emotional value to items like food and money (the ventral striatum and the insula) and also in a region thought to integrate different approaches to decision-making (the ventromedial prefrontal cortex). These systems are evolutionarily older than the rational brain.

And, how about One Overwhelming Way to Make Sense of It All? A Final Message for Thought?

Moral decision-making, Greene believes, “involves a whole lot of systems in the brain that are not specifically devoted” to that task alone; his results illustrate that even when humans are considering hypothetical moral scenarios or calculating abstract probabilities, they rely to some extent on emotions for guidance.

Thus rationality, unlike “manual mode” on a camera, cannot function independently of emotion, even in people who tend to be more rational—or utilitarian—decision-makers. “Reason by itself doesn’t have any ends, or goals,” Greene says. “It can tell you what will happen if you do this or that, and whether or not A and B are consistent with each other. But it can’t make the decision for you.”

Yet even though emotions will probably always affect people’s decisions, Greene thinks their input can—and should—be minimized in certain scenarios. By learning more about the neurological mechanisms of moral decision-making, he hopes that people may one day improve the judgments they make. “I think that we are too willing to rely on our automatic settings,” he says. “Our [emotions] are there for a reason and they do a lot of good, but they also get us into trouble in situations that they weren’t designed for.”

... would we have predicted this?

I'm going for a resonding yes.

PROBLEM: Though our neighborly ways make us vulnerable to being cheated and exploited, we've survived as intensely social creatures. University of British Columbia evolutionary psychologist Kiley Hamlin decided to find out how.

METHODOLOGY: Together with researchers Karen Wynn, Paul Bloom, and Neha Mahajan, Hamlin tested the ability of 100 babies to judge social behavior in scenarios where some puppets were less than nice. In one setup, the infants chose their favorite animal hand puppets after watching them either give or take away toys from other "good" or "bad" puppets. The scientists also examined 64 older infants aged 21 months, who were asked to reward or punish characters that previously helped or harmed another puppet.

RESULTS: Five-month-old infants uniformly preferred the puppets that acted positively toward their fellow puppets. Eight-month-old babies, however, were more selective. They exhibited a preference for puppets that were friendly over those that were mean. The older infants physically manifested this inclination by taking treats away from the bad puppets and giving them to the good ones.

CONCLUSION: By eight months, babies can comprehend the notion of reciprocity and can evaluate complex social situations.

IMPLICATION: The findings provide new insights into the protective mechanisms humans use to choose social alliances. Hamlin says in a statement: "From as early as eight months, we are watching for people who might put us in danger and prefer to see antisocial behavior regulated."
