Thought in Amsterdam

2009/08/04 at 11:09 am | In Cognition, Thought | Leave a Comment

Attending a conference for me is like a mid-term exam, a supply, and a oppotunity to realize who I am. This is my third time I attend CogSci, and its variate approaches has been a normal status for me. The cross-disciplines research approach under “cognition” will generate a variate of research topics in this generation. Being a cognitive scientist must remain this in mind seconds and hours. I also break the root caused my frustration in these months.

The university where I am working is a Buddist university which is built on the medical shcool but is unfamilier with the trend of cogntive science. My arrivial is their first time to open a window for this campus to understand what are the cognitive scientists are thinking on this world. These months I found a mistake I had made since I was applied: I am eager to build my lab and push students toward the core of my research. Most people here are blank paper to the cognitive science which is working to speculate human mind in several sophiscated ways to connect the behavioral data and abstract models. Psychologists have took 100 years develop a standard psycho lab working for this goal. I have take more paitient help the people here to realize the trend of cognitive science have came to them. Putting this goal upon the other personnal research plans will help me expand the space in this campus and whole east Taiwan.

I identy myself a psychologist who criticize each issue according to the connections between the theories and the collected experimental data. This is why only three spoken presentations impressed me in the venue. First is Athanassios Protopapas’ Greek nonword reading, and he is the author of CheckVocal. He has attempted to verify if the orthography-to-phonology rules dominates the behavior of reading Greek nonwords, because almost Greek words are consistent in mapping relations. He assumed the Greek readers will pronunce the nonword by rule if the grapheme-phoneme conversion is the matter. Although I have not realized his detail at this moment, he concluded more alternative factors, such as the neighborhood size, decide the experimental results as well. I am fortune had a talk with him before the end of the conference, and I guess he will be a factor when the day the the Chinese case come to the researchers who care the general othrogray-to-phonology issue.

Seidenberg’s crew brought the second impressed presentation about the inspection of matro behavioral reserach, like ELP. I also made a small test like them: to replicate one published study in terms of factorial design. Like their “virtual experiments” show, no experiments could be perfectly “replicated” by any known behavioral database. Task circumstance should be the matter because every reseracher had the specific arrangement of stimuli list, presentation and response procedure, and the instruction, etc. Their work could be a feedback to the pessimistic view of Balota: the factorial design still has its contribution to theories building.

The third one brought by Laurie Feldman wake my “psychonomic” sense up. She puts her focus on the affection of speaker’s accent on the reader’s/participant’s visual reading.  Reasonably she compared three groups of participsnts from the US, Japan, and China. All of her participants read English target words after the aditory primes presented in the accent of native language (for participants) or in the accent of second language. If the accent affects the participants lexical processing, the participants will show more interference when they hear the accent of second langauge. Her data show more interference occured to the American participants compared to the Japaness and Chinese participants. Based on this trend, I asked her immediately if she controlled the experience of living with second lanague for each group of participants. She admitted she did not and will think more problem behid this control. Furthermore, I assume the phonological neighbors accross languages would be the matter of this issue.

Among the book salesmen/women, I huntted three books being helpful for my current status: “Cognitive and cultural influences on eye movements” edited by Keith Rayner et al., “Clear and to the point: 8 psychological principles for compelling PowerPoint presentations” wrote by Stephen Kosslyn, and “LOT2″ worte by Jerry Fodor. Rayner’s articles will establish a plot of eyemovement studies in my mind. Kosslyn’s book is helpful to my poor skill of presentation. Jerry Fodor’s new book updates my knowledge about the debate about concepts among researchers. There will cost me much of time to comprehend and refresh my realization of the recent cognitive science. This is the original motivation I want to learn from congitive scientists: a continuous upgrading research individual and group depending on the open attitude to emerge any benefitial perspectives  for the investigation of human mind.

Sense of politics and sense of science

2009/01/31 at 4:47 pm | In Thought, politic | Leave a Comment

A speech error temporarily paused the process of president Obama sworn in his duty in the inaugural day. That is the situation the president followed Chief Justice Roberts’ words “solemnly swear that I will execute the office of president to the United States faithfully.” Mr. Obama had a pause after “execute” because he found the “faithfully” before “execute” was removed. This caused the other sworn in at the day after the inaugural day and Steven Pinker’s comment on this politics of language. One blogger criticized Pinker made a comment on the political perspective of Roberts instead of linguistic analysis, but a reader of Pinker’s books would realize this is his style. He always reveal his political orientation, medium libertarian, in his articles talking about the human nature or the evolution of human mind. A recent case is an article of individual genome on the New York Times.

The mostly interested part is the association of the political opinion and the perspective of science for a scientist. Pinker’s viewpoint to language establishes on the conceptual quirks stored in human mind. He argued that these quirks are the product of evolution and are inhered generation by generation. The unlimited combinations of quirks contribute the unlimited expressions of human languages. This argument is contrary to the generative grammar proposed by Noam Chomsky who is a famous left wing intellectual. Chomsky also has a gap in science and politics between him and Burrhus Skinner who believes a well designed reward system will improve the quality of individual behavior.  Across three generations, these minds who give extraordinary contribution to the modern psychology and cognitive science have so many differences in each aspect. So many different minds compete with each other in the circumstance each mind perform their potential as they can. I have to say it is why the US have been leading the development of science (at least in my domain) till present.

Is there other society providing  the  distinguished mind  contribute their potential regardless the political view? I think this is an interesting issue for more observations and experiences.

After Inaugural Day

2009/01/24 at 8:48 pm | In Cognition, Psychologist, Research, Thought | Leave a Comment

January, 20, 2009 is a day remarked the coming of new era for the American people. This year I also experienced the change within the research society I am contacting. At the day after the inaugural day, the top science journal “Nature” published a paper that will challenge the basic assumption accepted by every researchers depending on functional magnetic resonance imaging (fMRI). Dr. Sirotin and Dr. Das proposed the evidence that, in addition to the neural activity, a novel preparatory mechanism in the primates brain bring additional change to blood volume. I wonder the respond of my friends using fMRI as their research responds to this study. This news, in my opinion, is not totally bed for the future of cognitive neuroscience. This is the other opportunity for us to admit the complicated nature of the brain and to think of the bold but naive intention to build the link between brain and mind. The novel mechanism revealed by this study might be a caution for the optimistic views of building the link between behavior and brain function without sufficient understanding of behavioral facts.

The other change I am watching is the raising of the new perspective to the psycholinguists’ analytic tools. In the psycholinguistic studies, the generality of the empirical evidence is constrained by the variation of participants’ performance and the variation of stimuli property. For a group of stimuli with the same property according to a experimental definition, each stimuli usually generate a random effect within a wide variation. This situation increases the difficulty to conclude the effect of stimuli property based on the collected data. For a very long time, psycholinguists like to use by-item analysis for the confirmation of the observed effects. With the thousands of data accumulated, more and more psycholinguists have a thought if this analytic tool is really helpful to make conclusions. We might be expanding the frontier with an inaccurate compass. Keeping this awareness is what we should take care hour and hour in doing the psycholinguistic studies. Further reading about this issue is in the last volume of journal of memory and language, 2008.

New eye to see language

2008/12/11 at 10:30 am | In Cognition, Language, Research, Thought | Leave a Comment

Like the color of hairs or the allergy to special substance, language is suggested to be a genetic mechanism created by a long evoluation process. This concept is the agreement for many scientific disciplines that explore human nature being able to communicate with language. As Marc Hauser and Thomas Bever emphasize, human neural system make us learn and use our knowledge of language seperated from the other abilities to communicate. This biological aspect of language surrounds the rules and constraints constituenting a mature individual’s knolwedge of language. All paricipanted scientific disciplines have the tasks to understand the acquisition and the mediation mechanism of these rules and constraints, to isolate the parts sharing with other animals, to trace their evolucation process, and to ask the usage of the knowledge in communicative expression. Hauser and Bever listed some study cases towarding these goals, but there is a far distance because each discipline has to break its boundary before connect with each other.

Take the issue of lexical processing I participant in as an example, there are many interesting topics waiting our investigations. Our goal is to illustrate the temporal relation between the lexical property of words and the reading performance. A pressumption under this goal is that our knowledge of language underlying the processing decides the temporal relation. The known temporal relations just cover parts of rules and constraints identified by linguistists. One reason restricting us to look at a few temporal relation is the structure of exerpimental design. An observed effect on the performance needs an appropriate fit among variables, and the serach of such an effect usually costs a series of experiments. We have broad image to connect our findings and other disciplines, but we have a extraordinary patient to accumulate the knowledge till the break of boundry. After all, the undating of scientific knolwedge is a slow process which most people are hard to understand in their daily life.
