Language Learning and Teaching (стр. 20 из 46)

Learning styles might be thought of as "cognitive, affective, and physi­ological traits that are relatively stable indicators of how learners perceive, interact with, and respond to the learning environment" (Keefe 1979:4). Or, more simply, as "a general predisposition, voluntary or not, toward pro­cessing information in a particular way" (Skehan 1991: 288). In the enor­mous task of learning a second language, one that so deeply involves affective factors, a study of learning style brings important variables to the forefront. Such styles can contribute significantly to the construction of a unified theory of second language acquisition.

Learning styles mediate between emotion and cognition, as you will soon discover. For example, a reflective style invariably grows out of a reflective personality or a reflective mood. An impulsive style, on the other hand, usually arises out of an impulsive emotional state. People's styles are determined by the way they internalize their total environment, and since that internalization process is not strictly cognitive, we find that physical, affective, and cognitive domains merge in learning styles. Some would claim that styles are stable traits in adults. This is a questionable view. It would appear that individuals show general tendencies toward one style or another, but that differing contexts will evoke differing styles in the same individual. Perhaps an "intelligent" and "successful" person is one who is "bicognitive"—one who can manipulate both ends of a style continuum.

If I were to try to enumerate all the learning styles that educators and psychologists have identified, a very long list would emerge. From early research by Ausubel (1968:171) and Hill (1972), to recent research by Reid (1995), Ehrman (1996), and Cohen (1998), literally dozens of different styles have been identified. These include just about every imaginable sensory, communicative, cultural, affective, cognitive, and intellectual factor. A select few of those styles have emerged in second language research as potentially significant contributors to successful acquisition. These will be discussed in the next sections.

Field Independence

Do you remember, in those coloring books you pored over as a child, a picture of a forest scene with exotic trees and flowers, and a caption saying, "Find the hidden monkeys in the trees." If you looked carefully, you soon began to spot them, some upside-down, some sideways, some high and some low, a dozen or so monkeys camouflaged by the lines of what at first sight looked like just leaves and trees. The ability to find those hidden monkeys hinged upon your field independent style: your ability to perceive a particular, relevant item or factor in a "field" of distracting items. In general psychological terms, that "field" may be perceptual, or it may be more abstract and refer to a set of thoughts, ideas, or feelings from which your task is to perceive specific relevant subsets. Field dependence is, con­versely, the tendency to be "dependent" on the total field so that the parts embedded within the field are not easily perceived, although that total field is perceived more clearly as a unified whole. Field dependence is synony­mous with field sensitivity, a term that may carry a more positive conno­tation.

A field independent (FT) style enables you to distinguish parts from a whole, to concentrate on something (like reading a book in a noisy train station), to analyze separate variables without the contamination of neigh­boring variables. On the other hand, too much FI may result in cognitive "tunnel vision": you see only the parts and not their relationship to the whole. "You can't see the forest for the trees," as the saying goes. Seen in this light, development of a field dependent (FD) style has positive effects: you perceive the whole picture, the larger view, the general configuration of a problem or idea or event. It is clear, then, that both FI and FD are necessary for most of the cognitive and effective problems we face.

The literature on FI/D has shown that FI increases as a child matures to adulthood, that a person tends to be dominant in one mode or the other, and that FI/D is a relatively stable trait in adulthood. It has been found in Western culture that males tend to be more FI, and that FI is related to one of the three main factors traditionally used to define intelligence (the ana­lytical factor), but not to the other two factors (verbal-comprehension and attention-concentration). Cross-culturally, the extent of the development of a FI/D style as children mature is a factor of the type of society and home in which the child is reared. Authoritarian or agrarian societies, which are usually highly socialized and utilize strict rearing practices, tend to produce more FD. A democratic, industrialized, competitive society with freer rearing norms tends to produce more FI persons.

Affectively, persons who are more predominantly FI tend to be gener­ally more independent, competitive, and self-confident. FD persons tend to be more socialized, to derive their self-identity from persons around them, and are usually more empathic and perceptive of the feelings and thoughts of others.

How does all this relate to second language learning? Two conflicting hypotheses have emerged. First, we could conclude that FI is closely related to classroom learning that involves analysis, attention to details, and mas­tering of exercises, drills, and other focused activities. Indeed, recent research supports such a hypothesis. Naiman et al. (1978) found in a study of English-speaking eighth, tenth, and twelfth graders who were learning French in Toronto that FI correlated positively and significantly with lan­guage success in the classroom. Other studies (L. Hansen 1984, Hansen & Stansfield 1983, Stansfield & Hansen 1981) found relatively strong evidence in groups of adult second language learners of a relationship between FI and cloze test performance, which in some respects requires analytical abilities,

Chapelle and Roberts (1986) found support for the correlation of a FI style with language success as measured both by traditional, analytic, paper-and-pencil tests and by an oral interview. (The latter finding—the correla­tion with the oral interview—was a bit surprising in light of the second of our two hypotheses, to be taken up below.) Abraham (1985) found that second language learners who were FI performed better in deductive lessons, while those with FD styles were more successful with inductive lesson designs. Still other studies (Chapelle & Green 1992, Alptekin & Atakan 1990, Chapelle & Abraham 1990) provide further evidence of supe­riority of a FI style for second language success. More recently, Elliott (1995a, 1995b) found a moderate correlation between FI and pronuncia­tion accuracy. And in a review of several decades of research on Fl/D, Hoffman (1997: 225) concluded that "further research ... should be pur­sued before the hypothesis that there is a relationship between FD/1 and SLA is abandoned."

The second of the conflicting hypotheses proposes that primarily FD persons will, by virtue of their empathy, social outreach, and perception of other people, be successful in learning the communicative aspects of i second language. While no one denies the plausibility of this second hypothesis, little empirical evidence has been gathered to support it. The principal reason for the dearth of such evidence is the absence of a true test of FD. The standard test of FI requires subjects to discern small geo-metric shapes embedded in larger geometric designs. A high score on such embedded-figures tests indicates FI, but a low score does not necessarily imply relatively high FD. (This latter fact has unfortunately not been recog­nized by all who have interpreted results of embedded-figures tests.) Sow are left with no standardized means of measuring FD, and thus the second hypothesis has been confirmed largely through anecdotal or observational evidence.

The two hypotheses could be seen as paradoxical: How could FD be most important on the one hand and FI equally important? The answer to the paradox would appear to be that clearly both styles are important. The two hypotheses deal with two different kinds of language learning. One kind of learning implies natural, face-to-face communication, the kind of communication that occurs too rarely in the average language classroom. The second kind of learning involves the familiar classroom activities: drills, exercises, tests, and so forth. It is most likely that "natural" language learning in the "field," beyond the constraints of the classroom, requires a FD style, and the classroom type of learning requires, conversely, a FI style.

There is some research to support such a conclusion. Guiora et al. (1972b) showed that empathy is related to language acquisition, and though one could argue with some of their experimental design factors (see H.D. Brown 1973), the conclusion seems reasonable and also support­able by observational evidence and intuition. Some pilot studies of FI/D (Brown 1977a) indicated that FI correlated negatively with informal oral interviews of adult English learners in the United States. And so it would appear that FI/D might provide one construct that differentiates "class­room" (tutored) second language learning from "natural" (untutored) second language learning.

FI/D may also prove to be a valuable tool for differentiating child and adult language acquisition. The child, more predominantly FD, may have a cognitive style advantage over the more FI adult. Stephen Krashen (1977) has suggested that adults use more "monitoring," or "learning," strategies (conscious attention to forms) for language acquisition, while children uti­lize strategies of "acquisition" (subconscious attention to functions). This distinction between acquisition and learning could well be explicated by the FI/D dichotomy. (See Chapter 10 for further discussion of Krashen's Monitor model.)

FI/D has been conceived by psychological researchers as a construct in which a person is relatively stable. Unfortunately, there seems to be little room in such research for considering the possibility that FI/D is contextualized and variable. Logically and observationally, FI/D is quite variable within one person. Depending upon the context of learning, individual learners can vary their utilization of FI or FD. If a task requires FI, individ­uals may invoke their FI style; if it requires FD, they may invoke a FD style. Such ambiguities fueled Griffiths and Sheen's (1992: 133) passionate attempt to discredit the whole FI construct, where they concluded that this "theoretically flawed" notion "does not have, and has never had, any rele­vance for second language learning."

Carol Chapelle (1992; see also Chapelle & Green 1992), in a more bal­anced and optimistic viewpoint on the relevance of FI to communicative language ability, exposed flaws in Griffiths and Sheen's remarks and sug­gested, as did Hoffman (1997), avenues of future research. I surmise from Chapelle's comments that her optimism springs from—among other things—our acceptance of the view that FI and FD are not in complemen­tary distribution within an individual. Some persons might be both highly FI and highly FD as contexts vary. Such variability is not without its paral­lels in almost every other psychological construct. A generally extroverted person might, for example, be relatively introverted at certain times. In second language learning, then, it may be incorrect to assume that learners should be either FI or FD; it is more likely that persons have general inclinations, but, given certain contexts, can exercise a sufficient degree of an appropriate style. The burden on the learner is to invoke the appropriate style for the context. The burden on the teacher is to understand the pre­ferred styles of each learner and to sow the seeds for flexibility.

Left- and Right-Brain Functioning

We have already observed in Chapter 3 that left- and right-brain dominance is a potentially significant issue in developing a theory of second language acquisition. As the child's brain matures, various functions become lateralized to the left or right hemisphere. The left hemisphere is associated with logical, analytical thought, with mathematical and linear processing of infor­mation. The right hemisphere perceives and remembers visual, tactile, and auditory images; it is more efficient in processing holistic, integrative, and emotional information. Torrance (1980) lists several characteristics of left and right-brain dominance. (See Table 5.1.)

While we can cite many differences between left- and right-brain characteristics, it is important to remember that the left and right hemispheres operate together as a "team." Through the corpus collosum, messages are sent back and forth so that both hemispheres are involved in most of the neurological activity of the human brain. Most problem solving involves the capacities of both hemispheres, and often the best solutions to problems are those in which each hemisphere has participated optimally (see Danesi 1988).We must also remember Scovel's (1982) warning that left-and right- brain differences tend to draw more attention than the research warrants at the present time.

Nevertheless, the left-/right-brain construct helps to define another useful learning style continuum, with implications for second language learning and teaching. Danesi (1988), for example, used "neurological bimodality" to analyze the way in which various language teaching methods have failed: by appealing too strongly to left-brain processes, past methods were inadequately stimulating important right-brain processes in the language classroom. Krashen, Seliger, and Hartnett (1974) found support for the hypothesis that left-brain-dominant second language learners preferred a deductive style of teaching, while right-brain-dominant learners appeared to be more successful in an inductive classroom environment. Stevick (1982) concluded that left-brain-dominant second language learners are better at producing separate words, gathering the specifics of language, carrying out sequences of operations, and dealing with abstraction, classification, labeling, and reorganization. Right-brain-dominant learners, on the other hand, appear to deal better with whole images (not with reshuffling parts), with generalizations, with metaphors, and with emotional reactions and artistic expressions. In Chapter 3 I noted the role of the right hemisphere in second language learning. This may suggest a greater need to perceive whole meanings in those early stages, and to ana­lyze and monitor oneself more in the later stages.

You may be asking yourself how left- and right-brain functioning dif­fers from FI and FD. While few studies have set out explicitly to correlate the two factors, intuitive observation of learners and conclusions from studies of both hemispheric preference and FI show a strong relationship. Thus, in dealing with either type of cognitive style, we are dealing with two styles that are highly parallel. Conclusions that were drawn above for FI and FD generally apply well for left- and right-brain functioning, respectively.

Ambiguity Tolerance

A third style concerns the degree to which you are cognitively willing to tolerate ideas and propositions that run counter to your own belief system or structure of knowledge. Some people are, for example, relatively open-minded in accepting ideologies and events and facts that contradict their own views; they are more content than others to entertain and even inter­nalize contradictory propositions. Others, more closed-minded and dogmatic, tend to reject items that are contradictory or slightly incongruent with their existing system; they wish to see every proposition fit into an acceptable place in their cognitive organization, and if it does not fit, it is rejected.
