Summary of responses to request for information on Judgment Fatigue (Also called Syntactic Satiation) Original post: LINGUIST List: Vol-6-974. Mon Jul 17 1995. ISSN: 1068-4875. Special thanks to the following respondents: Kimberly Barskaitiki, Tim Beasley, Elizabeth Bergman, Michael Bernstein, Vivian Cook, Joseph Davis, Rianne Doeleman, Karen Emmorey, Suzette Haden Elgin, Ted Harding, Stephen Helmreich, Erika L. Konrad, John E. Limber, Bruce Nevin, John Robert Ross, Carson T Schutze, Linda Shockey, William Snyder, Karin Stromswold, Joyce Tang Boyland, anyone I may have missed, and anyone who thought about responding but hasn't yet. Karin Stromswold and William Snyder have actually investigated this phenomenon. I have not read either of their papers yet, but I look forward to doing so. William Snyder (snyder@psyche.mit.edu) presented a poster on this topic at LSA 1994, which was mentioned in Rick Hudson's summary post of July 29, 1994. Individual's interested in Dr. Snyder's poster should contact him directly. Hudson's post (LINGUIST List: Vol-5-855. Fri 29 Jul 1994. ISSN: 1068-4875.) summarized the literature available which addresses the difference between linguists' and non-linguists' intuitions. Hudson also mentions (but does not cite) four references provided by Joyce Tang Boyland regarding satiation effects (both syntactic and semantic). Hudson's original post is available from Linguist List archives. Joyce Tang Boyland's response is included below (in Part II of post, following). Karin Stromswold's response (karin@muddle.rutgers.edu) was my connection to Snyder, Hudson, and Boyland. Her post is most relevant to my original query and is included in its entirety below (in Part II of post, following). Most responses mentioned the influence of continual or repeated exposure over a period of time, either mentioning examples similar to perceptual or semantic satiation such as a word-repetition effect. (Bergman, Cook, Davis, Doeleman, Haden Elgin, Harding, Helmreich, Limber, Schutze, Snyder, Stromswold, Tang Boyland). There are many differences, however, between the effects of semantic satiation and "syntactic satiation" or judgment fatigue: First, semantic satiation is the detachment of form and meaning which occurs as you continuously repeat some lexical item (see also Stromswold's post below). Judgment fatigue, in contrast, cannot be induced by the repeated presentation of any sentence. In fact, published experiments by Nagata show that raters' intuitions only become more stringent on repeated presentation. Second, the loss of the meaning of a sentence is not an effect of judgment fatigue. The meaning of the sentence may be quite lucid to the individual reading it, but that individual's attention is focused upon some aspect of the grammatical acceptability of the sentence, and it is the ability to judge grammatical acceptability which is lost, not the ability to make sense of the utterance. Third, while the particular characteristics of the stimuli which induce judgment fatigue are not yet fully established, it appears that different types of sentences induce the effect to different degrees (Stromswold, Snyder as cited in Hudson's post). This is not the case for semantic satiation, where the repetition of any lexical item can induce the effect. Fourth, the "scanting out" effect as noted by Haj Ross points out that the loss of intuition can be triggered by one single stimuli, not necessarily the repeated presentation of numerous stimuli (relevant quote posted below). Conversely, subjects can rate hundreds of stimuli on the basis of grammaticality, with no fatigue effect (beyond boredom), even if the stimuli contain permutation of the same lexical items, be they open or closed class items. Note that point four is definitely true in the case that the stimuli are all dichotomously "great--grammatical" or "horrible--ungrammatical". There is a definite influence of marginality, an effect which, to date, I believe no one has explained. Fifth, semantic satiation (as well as perceptual fatigue effects) is often attributed to some type of neurological fatigue at the cortical level. This could not be the (only) reason for judgment fatigue, however, because there may not be any single word or syntactic structure which is repeated in all of the stimuli (such as could be the case for judgment fatigue induced by the scope of negation or negative polarity items). For this reason, it would be quite implausible to claim that judgment fatigue is the result of some type of physiological / chemical / neurological saturation which has occurred at the cortical level. At this point, I do not believe judgment fatigue and semantic satiation have much in common as behavioral disturbances. (Incidently, while I am not an expert on semantic satiation, I have not yet been forced by the evidence to believe that semantic satiation is the result of a low-level neurological fatigue. Perceptual fatigue is a neurological phenomenon, but I attribute semantic satiation to other conceptual strategies.) Many linguists (Beasley, Nevin, Konrad, and one anonymous) also observed 'that the longer you stay in linguistics, the less you speak English.' To quote from Bruce Nevin's response: << A student was once asked, in my hearing, if a certain famous linguist was a native speaker of English. The reply: 'I think he used to be.' >> Hudson's previous summation further confirms that linguists and non-linguists do demonstrate significantly different abilities in discriminating grammatical and ungrammatical sentences. This type of long-term "drift" of linguists' judgments may be of interest in its own regard, but this type of "judgment drift" is not identical to the temporary loss of linguistic intuition which I intended to address. As noted by Beasley and Konrad, it may indeed be the case that exposure to second languages, exposure to dialects different from ones native dialect, or exposure to a large number of perhaps marginal sentences which occur rarely in natural spoken or written contexts (such as sentences demonstrating violations of theoretical principals such as "weak crossover" or "island constraints", for example) may actually alter an individual's criteria for grammatical acceptability. If one understands judgments of grammatical acceptability to be metalinguistic type-categorizations, then one may expect that an individual's discriminative ability will be altered based upon that individual's personal experiences with exemplars of the categories. Others commented that judgment fatigue does not happen if the stimuli are contextualized (Davis, Nevin) or if the referential situation is more concrete rather than abstract (Davis, Doeleman, Nevin). This is not the case. A loss of linguistic intuition of grammatical acceptability definitely can happen spontaneously, such as while one is listening to a conversation or reading texts, regardless of the concreteness of the topic, with the following qualifications: judgment fatigue is inspired only by particular types of stimuli (which have not yet been clearly defined, but see Part II of post, following) and by the listener's / reader's focus upon the grammar of the utterance or sentence. Other individuals related hard-to-comprehend sentences as examples inducing judgment fatigue. Some such sentences, notably sentences involving scope ambiguity, may induce confusion, but confusion is not synonymous with the loss of ones own linguistic intuitions. For ambiguous or confusing stimuli, we say, "Someone should rewrite this sentence. It is ambiguous (or anomalous)." When we have judgment fatigue, we say, "I'm a monoglot, but damned if I can decide whether this sentence is grammatical. I sure don't FEEL like a native English speaker!" Lastly, some responses or general expressions of empathy or encouragement, and actual examples (Barskaitiki, Emmorey, Shockey). Thank you again to all who responded. If you are interested in the current proposal for my experiments, or if you would like to hear more about the results and conclusions from the experiments when I am finished running them, please contact me. The following are what I found to be especially informative quotes from four individual respondents who gave specific comments regarding the types of stimuli which tend to induce judgment fatigue. Kimberly Barskaitiki also sent a long, specific, detailed response with many interesting examples. (Thank you!) Her response is not included here because it presented fewer strong, testable, theoretical claims. (I must note here that Ross and Beasley are quoted without their expressed permission, for which I hereby beseech the authors' belated dispensations. I post all comments here in only the most charitable light, with the hope of sharing the author's experience and information.) ************** From: Karin Stromswold (karin@ruccs.rutgers.edu) >As a graduate student at MIT in 1986, I wrote a paper on the >phenomenon you described for a course I took with Merrill Garrett.
