5. Interactive and Attentive

When I was thirteen years old an elderly woman stepped off a bus carrying a grocery bag with a strained look on her face as she struggled to maintain balance. I offered to help and grabbed the bag, shifting its awkward weight between my arms during the two-block jaunt to her home. She expressed gratitude for the assistance when I placed it on her kitchen table.

It was 'instinctive' to help when I saw her manipulating the bag with some difficulty. I would not walk her home if she had no bag and would not help if an able-bodied man carried the load. The recognition that an elderly person was uncomfortable drew my attention and it made sense to help. There were a few underlying reasons why I volunteered to carry that bag of groceries, among them my love for my grandparents, and perhaps recognition that it would be morally wrong to not intercede for this person.

Scientists today may attribute my service to mirror neurons, nerve cells in our brain that map the pictorial description of actions from the higher order visual areas onto my motor counterpart. That is, (a) I saw the wiggly movement of the bag in her arms, the strained look on her face, and concluded that she was uncomfortable. (b) I knew how overloads can be awkward because my motor cortex has a memory of struggles maneuvering heavy objects. (c) It led to feelings of empathy and the decision to provide assistance. The mirror neuron system, for instance, is activated when after observing a friend yawn, you do likewise. It is part of the cognitive engagement process.

Neurophysiologists in the early 1990s at the University of Parma in Italy discovered mirror neurons originally in monkeys when electrodes in the somatosensory cortex region of the brain fired as they moved their arms to pick up an object. What put them in the context of 'mirror' neurons occurred accidently when a researcher picked up that object and the monkey's neurons fired. In other words, the part of the brain that fired when the monkey used a set of muscles also fired when the monkey saw a human perform the task. A subsequent cluster of studies confirmed that humans have mirror neurons.1,2

What is the connection between mirror neurons and attention? For one, it accounts for the capacity to observe and then replicate an action such as a dance because the movement we observe is already coded in the motor region of our brain, most likely because we did a similar gyration in our past. If not a match when we try, the performance is perfected with practice. Think of all the athletic moves we see daily by ballplayers, the coaching that improves upon the models to make the execution perfect, along with video reviews by athletes to fine tune their skills. Children imitate what they observe from televised ballgames or playmates in their neighborhood.

Another implication of the mirror neuronal system is empathy, what I experienced when the woman lugged the bag off the bus. Observing suffering animals and children on infomercials prompt us to donate funds to organizations that relieve suffering. Propping a door open at a shopping center for the people behind us is another example of the empathy mechanism in action – we are saving a person the exertion required to open the door or prevent its sudden closure. It is the reason we are captivated by movies because actors trigger emotions within our empathetic memory, even to the point of crying or laughing.

In addition, the mirror neuronal system helps us understand gestures and their emotional context.3 The musculature of our face is capable of many configurations and the basic gestures of anger, happiness, sadness, fear, surprise, and disgust is universal. We may not comprehend them as young children but recognize the emotional connection as we age and is a vital element in human communication. For example, consider the ramifications when another person engages you with eye contact and smiles, setting off the endorphin flow that makes you happy: that person's gesture activates your visual cortex, sets off the mechanism via mirror neurons to trigger the feeling and generate a return smile.

Essentially, then, the same region of the brain is activated whether you are seeing or making a facial expression. Also, people with well-developed mirror neuronal systems are better at interpreting gestures and prosody and therefore have greater perceptive and empathetic qualities. Hall and Cook believe that schools and parents that foster validation build a more powerful internal locus of control in children, making the cerebral world more understandable at the emotional level and able to relate to others empathetically. Children with a better internal locus of control "think optimistically, manage time, and find meaning" in order to "increase their sense of happiness."4(p. 49) 

They tend to be less impulsive as well. People were instructed on how to interpret human gestural and vocal signals during the assertiveness movement of the 1970s applying conflict resolution and dignified conversations to express feelings, aspirations, and goals in a tone that was not threatening. It is a process where you become attuned to your own emotional triggers and regulate behavior accordingly.

Not only are the visual and motor cortices involved in the mirror neuronal network but the prefrontal lobes, too. The elucidation of body language and expressions becomes part of your long-term memory, which also manifests reasoning, moral judgment, and planning. (That is perhaps why I helped that woman with her groceries rather than go directly home.)

Given that there is an interplay between the prefrontal cortex and amygdala that mediates fear and calm, the maturation of facial recognition might be a critical component in an individual's ability to work with others in an engaged manner to complete tasks.

Human Interaction Studies

The following brain scan and physiology studies reveal how communication is amplified during verbal and face-to-face encounters.

Talking and listening

One example of how human attentiveness has ramifications in the brain was done by Greg Stephens and Uri Hasson, Professors of Psychology at the Princeton University. They used fMRI to scan the spatiotemporal brain activity of a person as they read a story into a tape recorder. They then scanned another person who listened to the recorded story. There was no face-to-face interaction in this experiment. They found the listener's brain pattern mirrored the speaker's, with a slight time delay. In some cases, it coincided perfectly, as if the listener was anticipating the words from the speaker. The listener was tested for comprehension after they heard the story and demonstrated greater comprehension or high neural coupling.

Comprehension, therefore, is facilitated by predicting upcoming words, and successful communication requires the active engagement of the listener. Furthermore, the coupling crossed many brain areas "aligning with phonetic, phonological, lexical, syntactic, and semantic representations as well as processing social information crucial for successful communication, including, among others, the capacity to discern the beliefs, desires, and goals of others".5
For instance, if you go to a restaurant and say: "Coffee, two sugars" a thought process transpires in the waiter:  Go to the brewing machine, grasp the coffee urn, pour until it reaches within half-inch of the top of the mug, add two cubes of sugar, stir until dissolved, and bring it to the patron at table sixteen before his egg and toast order is ready (but only after I attend to the orders at tables seven and ten).

Face-to-face versus back-to-back

Face-to-face interaction was examined by a team from Beijing Normal University using Functional Near-Infrared Spectroscopy (fNIRS), which looked at a region in the frontal cortex to compare synchronization under different settings.  Four male–male pairs and six female–female pairs were scanned during four task sessions sitting: (1) face-to-face with dialog, (2) face-to-face with only one speaker, (3) back-to-back with dialog, and (4) back-to-back with only one speaker. They were videotaped as well, and the researchers examined interactions for turn-taking behavior including body language: orofacial movements and gestures.

They found neural synchronization at a maximum in the left inferior frontal cortex only in the face-to-face dialog scenarios. They concluded that: "multimodal sensory information integration and turn-taking behavior between partners may underlie successful face-to-face communication."6 They add that the human brain is designed for face-to-face communication and has important neural features that other types of communication lack (email and text messaging), and recommend that people take more time communicating face-to-face.

Eye contact

The amygdala as discussed earlier receives a vast array of sensory signals from the environment and evaluates their potential to threaten the safety of an individual. More specifically, it processes another's gaze as the first line of information about external cues such as objects, events, individuals, and internal cues like emotions, beliefs, desires, and intentions. Primates are social entities and make eye contact to communicate emotions and gather information about the intention of others.7

By targeting three hundred eighteen neurons in the amygdala of three Rhesus macaques, Katalin Gothard, a neurophysiologist at the University of Arizona in Tucson, and her team, noted twelve percent selectively changed their firing rate when the subject fixated on the eyes of monkeys in movies – sort of a brain boost when eye contact is established. In this study Gothard found that amygdala neurons are affected, and specifically when monkeys make eye contact with other monkeys. In other words, identity-selective cells in the amygdala distinguish facial expressions that lead to the emotional response behavior to another individual.

The idea that, in the amygdala, the most socially salient stimuli elicit the highest firing rates holds true: at the population level, neurons that signal eye contact elicit the highest of firing rates, similarly to threatening faces that elicited higher firing rates than neutral and appeasing expressions.8

Gothard is telling us that eye contact raises the level of engagement in primates, a vital element in communication, and when coupled with facial expressions, provides social and emotional information. People routinely search eyes and faces for positive or negative mood signs and respond based on that information. Comments about eye contact:

-"One of the basic elements of the social system, forming a significant part of individual socialization and experience gaining throughout one's lifetime."9
-"The gold standard of communication and the most efficient and informational one."10
-"Engages more human senses than mediated communication."11
-"Is the best form of teaching".12



Laughter

In-services are a nice break because you have a pause in your day-to-day teaching, a chance to hear outside speakers and touch base with colleagues. I take the opportunity to organize my laboratory and sort files, time permitting. I walk into them a bit lethargic at eight a.m., however, anticipating long, drawn out talks and lots of sitting. In fact, on one occasion we were told that the school enlisted an educational psychologist from a nearby university to speak about lesson plan organization. We expected a real yawner but was surprised by his humor, tying content to funny anecdotes and puns. I enjoyed his presentation and experienced a surge of energy and mental alertness, apparently setting off a series of hormonal reactions that affected my mood for an extended period. There were many instances when a joke or smile livened my disposition during a school day.

I was a teacher that desired approval from students and worried about boring them, and incorporated humor in my lessons, usually weird anecdotes about my high school and college days. The kids loved the stories as reflected by their smiles and laughs, and even played tape-recorded segments of popular comedians from the radio. I was trying to get the attention of my entire class to prevent the slumping or socializing that were common in my first year of teaching, finding laughter a way to interact with my students and raise their engagement level.

Humor should be part of the classroom, not sarcasm, but spontaneous anecdotes or even a joke from time to time. Humans are the only species that laugh, and there are neurological explanations why humor is beneficial. Depending on the type of joke, the prefrontal cortex, an area associated with judgment and planning, is activated, particularly in the areas of language processing and ambiguity resolution.

Laughter has neurological and physiological consequences

Peter Derks, professor of psychology at the College of William and Mary, in 1997 exposed people to humorous material and evaluated their brain's response using electroencephalograms (EEG). He found that pulses traverse broad regions across the cortex, the frontal lobes, and the midbrain. Humor is thus complex because the incidental sensory stimulation, whether visual, auditory, or even touch (tickling) sets off intellectual, emotional, as well as visceral responses. Is it funny? Is it a laugh aloud or giggle or smile joke?13,14

We touched base earlier with the important interplay between the prefrontal cortex and the midbrain (hippocampus and amygdala) as they pertain to motivation, reward, and fear. The laughter mechanism then employs the neurotransmitter dopamine, which targets the nucleus accumbens to sustain attention to complete tasks. There is the effect of the hormone oxytocin, too, that is involved in social bonding and even the pleasurable feeling that follows monetary gain or addictive drugs. Derks adds that funnier content increases blood flow to the nucleus accumbens as part of the neural circuitry of human socialization and mood, encompassing friendship, love, affection, and perhaps anger.

In his book A Better High: laugh, help, run, love…and other ways to get naturally high! Matt Bellace states:
When something is perceived as funny, the reward center of the brain is activated, the same area that is activated during cocaine-induced highs. I'm not going to argue that laughing is a more intense high than cocaine, but the brain knows how to balance a natural high.15

The dopamine released during a laughing high does not damage the brain but cocaine negatively affects the neurotransmitter chemistry of the brain. Cultural anthropologist Mahadev Apte concerning the work or school environment states: "Laughter occurs when people are comfortable with one another, when they feel open and free. And the more laughter, the more bonding within the group."16

Ed Dunkelblau, Director of the Institute for Emotionally Intelligent Learning, comments: 
In the present environment of high stakes testing, budgetary challenges, increased demands on educators and competition for student attention, everyone in the school benefits when humor is part of the pedagogy. Humor is a unique behavior that builds a learning relationship through the joyful confluence of head and heart. But most of all, it brings a sense of pleasure and appreciation and creates a common, positive emotional experience that the students share with each other and the teacher. Laughter then is the assertive (biochemical) response to an interpreted stimulus.17


Add humor to your classes
-Put humorous items such as quotes, icons, or jokes on tests, homework or class assignments.
-Have a bulletin board for humor quotes and post them as well as the students'.
-Maintain a cartoon file and display a few each week.
-Establish Joke Friday where students bring in their favorites.
-Have a weird hat day, or wrong paired socks day, or some other dress up theme.
-Bring a joke book to class and either read them yourself or have students find their favorite.17
-Personal anecdotes about your own life are appreciated.

Conclusion

Research institutes have delineated regions in the brain that fire during face to face interactions, identifying the heightened neurological and physiological effects of an assortment of communication scenarios in humans targeting those regions as well as chemical responses throughout the body that occur via voice, positional, eye contact, and laughter.

Interactive lessons have an affirming effect on cognition. It is in this scenario that students experience engagement, as student-led discussions and well-structured team-based assignments set off neurological effects that maximize retention and productivity.

In the socialization, we generate what Csikszentmihalyi and Hunter call flow activities that stretch their skills. Moreover, a balance between teachers and student presentations will generate the biochemical response that raises achievement and engagement of the full spectrum of personalities in the classroom.
