Conceptual Support for What We Do • • Knowles’ Adult Learner vs K-12 Experience Bandura’s Modeling Irwin Guthrie’s Behaviorist Model Schuman and Lee: Neurochemistry of Learning Churchland’s Critique of the Theory of Pure Vision and the Four F’s (fleeing, fighting, feeding and reproduction) Proctor and Dutta: Practice and Automaticity Schmidt: Unconscious and conscious sensory processing – Chunking and increasing the size of the chunks Bruer and Cognitive Science: There is no single critical period. There a bunch of them and we work to deal with them. Basically, work toward automaticity through practice and solid fundamentals. Control leads to success which motivates. Automaticity increases the size of the chunk. Technology is key to practice, collaboration, advanced use of language

The Structure of Learning

What Happens when we learn something?

What happens when we learn something (2)?

Role of Dopamines (DA) • DA strengthens synapses • Facilitates memorization and skill acquisition • Acts as driver toward learning and action • Facilitates and inhibits actions – D 1: Facilitates action (lack – Parkinson’s) – D 2: Inhibits competing actions (lack— Huntington’s) • Children’s brains are loaded with DA’s

Structure of DA Modulation • Dopamine-glutamate interactions in the nucleus accumbens. information-laden glutamatergic inputs (blue) impinge on medium-spiny neuron dendritic spines (yellow) where they are subject to DA (orange) modulation. While glutamate receptors (green) are located on the postsynaptic membrane, many DA receptors (red) are located extrasynaptically, consistent with DA having a modulatory role. Also, DA neurons are actually DA/glutamatergic neurons (orange/blue striped) capable of fast excitatory transmission. • In sum, Dopamine strengthens neuronal connections that encode and execute information and skills.

Why Children Learn So Well

Why Children Learn So Quickly and So Well • Because they are immature they need assistance to survive • Because they are programmed to survive, they are built for learning • What is not used goes away • DA drive is reinforced through opiates • The combination is about 100 times that of adults

Life Cycle (Ontogeny) of Dopamine (DA) • The densities of D 1 and D 2 dopamine receptors in the striatum rise and reach the highest level at the age of 3 or 4 and fall sharply until puberty for D 1 receptor and age of 5 for D 2 receptor. • After age 20, D 1 receptors disappear at 3. 2% per decade and D 2 at 2. 2%. • In adults, the receptor density is 48%(D 1) and 59%(D 2) less than that of children

Human Behavior: Seeking and Consuming

Ontogeny of Opioids, Vasopressin and Oxytocin • “In normal infants brain levels of opioids at birth are 100 times greater than levels later in life. ” (Waterhouse, Fein, & Modahl, 1996, p. 477). • Vasopressin and oxytocin: there is a transient, but marked “over-production” (relative to the adult) of both oxytocin and vasopressin receptors in limbic brain areas in the young brain (Insel and Winslow, 1998).

Motivation

The Neurochemistry of Motivation: Reiterated • Motivation is modulated by interplay of Dopamine (DA) and Opiates. • DA makes us and our students seek for goals • Opiates make us feel satisfied when goals are accomplished • The combination restarts seeking behavior. • DA strengthens the neuronal connections for declarative memory and procedural memory.

Considerations about the Adult Learner

Anatomy of Core Structures

The Brain Systems for Language Learning Cerebral Cortex Hippocampus (Declarative Memory) Dopamine (Motivation) Amygdala (Emotional M. ) Basal Ganglia (Procedural Memory)

Memory Taxonomy • Adult language learners count on three neural systems. • Declarative Memory System: guide and monitor rule formation and execution (e. g. explicitly knowing that the subject and the verb should agree in number and tense in English), encode vocabulary. • Procedural Memory System: encode and execute rules of grammar and phonology to the extend of automatization (e. g. automatically execute the S-V agreement). The most fundamental difference between Level 2 and Higher Levels is the extent of proceduralization of language skills. • Affect/Motivation System: strengthens both of the systems above.

Human Behavior: in a nutshell Goal Seeking w/ Strong DA Goal Seeking w/ weak DA Goal Achieving: Experiencing Opiate Fail: No Opiate Stop

Schumann’s Motivation Model Human motivation operates on the five planes of stimulus-appraisal as below. In other words, DA is produced (1994): • when an action is relevant to needs and goals; • when a stimulus is novel; • when an action promotes positive self and social image; • when an action is intrinsically present; and • when there is coping-potential.

Why are well-defined objectives Important? Answer from Neurobiology Unclear Objectives Clear Objectives Learning with strong motivation Success + DA - + Opiate - Learning with weak motivation No Success Stop Trying

What we are doing about all this?

Three DA Pathways

Structure of DA Modulation (in a wider context)

Caption for slide 15 reference The development and maintenance of affiliative bonds across two phases of reward. Distal affiliative stimuli elicit an incentive-motivated approach to an affiliative goal, accompanied by strong emotional-motivational feelings of wanting, desire, and positive activation. The approach phase not only ensures sociosexual interaction with an affiliative object, but also acquisition of a memory ensemble or network of the context in which approach, reward, and goal acquisition occur. Next, proximal affiliative stimuli emanating from interaction with the affiliative object elicit strong feelings of consummatory reward, liking, and physiological quiescence, all of which become associated with these stimuli, as well as the context predictive of reward. Dopamine encodes the incentive salience of contextual stimuli predictive of reward during the approach phase and, in collaboration with opiate mediated consummatory reward, encodes the incentive salience of proximal stimuli directly linked to the affiliative object. The end result of this sequence of processes is an incentive encoded affiliative memory network that continues to motivate approach toward and interaction with the affiliative object. Specialized processes ensure that affiliative stimuli are weighted as significant elements in the contextual ensembles representing affiliative memory networks. These specialized processes include the construction of a contextual ensemble via affiliative stimulus-induced opiate potentiation of dopamine processes, and the influence of permissive and/or facilitatory factors, such as gonadal steroids, oxytocin, and vasopressin on (i) sensory, perceptual, and attentional processing of affiliative stimuli and (ii) formation of social memories.

caption for slide 35 for your reference Binding of salient context with incentive motivation in the NASshell. The acquisition of contextual ensembles is strongly dependent on DA facilitation in the NASshell (Aosaki et al. 1994; Depue & Collins 1999; Everitt et al. 1999; Graybiel 1998; Jog et al. 1999; Meredith & Totterdell 1999; O’Donnell 1999; White 1997; Wickens et al. 1996). Corticolimbic brain regions carrying contextual information (right side of figure) innervate the heads of dendritic spines of NASshell projection neurons using glutamate as a transmitter; most of these efferents are excitatory to NAS function and are reciprocated. In addition, approximately 8, 000 VTA DA projections also innervate the dendritic shaft or spinal necks of each NAS spiny neuron. As illustrated in detail only at the proximal level of the dendrite for basolateral amygdala input (but occurring at all other input levels, as well), glutamate and DA can substantially increase release of each other via NMDA and D 1 receptors, respectively, located on terminals. In this way, DA is thought to strengthen the connections between inputs of the salient incentive context predictive of reward and incentive processes integrated in the NASshell. See text for details. (Abbreviations as in Figure 6, except Glu = glutamate; NMDA = N-methyl-D-aspartate glutamate receptor; LTP = long-term potentiation; D 1 = D 1 dopamine receptor).
