Does a theory of language need a grammar? Evidence from Hebrew root structure

Hebrew constrains the occurrence of identical consonants in its roots: Identical consonants are acceptable root finally (e.g., skk), but not root initially (e.g., kks). Speakers' ability to freely generalize this constraint to novel phonemes (Berent, Marcus, Shimron, & Gafos, 2002) suggests that they represent segment identity-a relation among mental variables. An alternative account attributes the restriction on identical phonemes to their feature similarity, captured by either the number of shared features or their statistical frequency. The similarity account predicts that roots with partially similar consonants (e.g., sgk) should be at least as acceptable as roots with fully identical consonants (e.g., skk), and each of these roots should be less acceptable than dissimilar controls (e.g., gdn). Contrary to these predictions, three lexical decision experiments demonstrate that full identity is more acceptable than partial similarity and (in some cases) controls. Speakers' sensitivity to consonant identity suggests that linguistic competence, in general, and phonology, in particular, encompass a computational mechanism that operates over variables. This conclusion is consistent with linguistic accounts that postulate a symbolic grammatical component that is irreducible to the statistical properties of the lexicon.     

Listening to speech at two levels at once

Monitoring performance was compared when subjects were asked to listen simultaneously for two different targets embedded in a sentence and when they listened only for one. The effects of different combinations of targets (phonemes, words, or meanings) were investigated and an attempt was made to separate the effects of particular combinations from the effects of difficulty of the two component targets. Performance was worse when either of two targets might occur than when subjects knew which single type to listen for. However there were no differences attributable to which particular types of targets were being combined. Listening for a phonemic target was as difficult to combine with listening for a semantic target as for another phonemic target. The result is consistent with a central speech analysing system whose limited processing capacity must be shared (at least in this monitoring task) both between and within all relevant levels of linguistic analysis, rather than with relatively independent subsystems for each type of listening.     

Sentential context and the interpretation of unambiguous words

Two experiments were carried out in order to investigate how the linguistic context (in the form of a sentence) facilitates the interpretation of unambiguous words. Experiment I established that if a sentential context as a whole is sufficient to evoke an inference that calls to mind a particular aspect of a word's meaning, the presence of a verb with appropriate selectional restrictions does not enhance the process. Experiment II showed that when no other cues are provided within a sentence, both verbs and adjectives are effective in enhancing a specific aspect of the meaning of a word. These findings were taken to support the hypothesis that in understanding a sentence, people instantiate particular aspects of the meanings of words in order to construct specific interpretations, and linguistic context guides this process of selection.     

Representing logical and semantic structure of knowledge acquired from discourse

A network model of logical and semantic structures from which speakers or writers generate linguistic messages at the discourse level is presented. While linguistic structures were considered in developing the model, the semantic and logical networks are defined without reference to linguistic structures and thus may be used to represent knowledge structures acquired from both linguistic and nonlinguistic sources. A second problem addressed is that of determining what logical and semantic information is acquired when a text is understood. To assess acquired knowledge, a procedure is presented for coding a subject's verbal reconstruction of knowledge acquired from a presented text (or other input) against the logical and semantic structure from which the text (or other input) was derived. The procedures are illustrated using data obtained from children who were asked to “retell” simple narrative stories.     

The effect of group-identification on emotion recognition: The case of cats and basketball players

It has been suggested that the in-group advantage in the recognition of emotional expressions by members of different cultural groups may be due to either encoder differences in expressive style or to decoder biases. The latter may be explained by the fact that individuals who identify with an ethnic or social group exert more effort when trying to decode the emotional expressions of group members. The present study investigates this notion. For this, two target groups were chosen such that in-group and out-group members shared the same cultural knowledge and linguistic background and all participants rated the same expressions to control for encoder differences. Both studies showed that individuals who identified with a social group were better at recognizing expressions by individuals perceived as members of that group.     

Other People’s Errors

The question of when other people’s bad acts belong on our moral ledger arises in a number of different scenarios. Each scenario has received some philosophical attention, but no one has noted the structural similarities of these various scenarios or the implications of a proposed approach to one for how the others should be approached. That is the ambition of this article. In it, seemingly disparate moral phenomena—blunt rules, preemptive restrictions, moral blackmail, complicity, retreat and proportional response, and the duty to rescue from a peril one has caused—are shown to have similar structures and thus to require similar moral approaches.     

Task switching and action sequencing

We investigated if task switching affects late response processes that occur after the selection of a response. Subjects performed a sequence of two responses. The first and second response were selected, and then executed in close succession. The interresponse interval (IRI) was taken as a measure of late response processes. The two responses could either belong to different tasks (task-switch condition), or to the same task that was performed twice (task-repetition condition). In all three experiments, the IRI was found to be longer in the task-switch condition than in the task-repetition condition, consistent with the idea that task switching affected late response processes. However, the effects of the manipulation of the stimulus-onset asynchrony revealed that the tendency to perform the two responses as a sequence was reduced in the task-switch condition relative to the task-repetition condition. Thus, the data do not provide unequivocal evidence for task switching affecting late response processes. The data show, however, that task switching affected action sequencing. Two actions that do not belong to the same task context are less likely to be performed as an action sequence. We suggest that task switching interacts with higher-order control processes that cannot be studied within the traditional task-switching paradigm.     

Shared and separate systems in bilingual language processing: converging evidence from eyetracking and brain imaging

The neurological and cognitive aspects of bilingual language processing were examined in late Russian-English bilinguals using headband-mounted eyetracking and functional neuroimaging. A series of three eyetracking studies suggested that, at early stages of word recognition, bilinguals can activate both languages in parallel, even when direct linguistic input is in one language only. A functional neuroimaging study suggested that, although the same general structures are active for both languages, differences within these general structures are present across languages and across levels of processing. For example, different centers of activation were associated with first versus second language processing within the left Inferior Frontal Gyrus, but not within the Superior Temporal Gyrus. We suggest that parallel activation (as found with eyetracking) and shared cortical structures (as found with fMRI) may be characteristic of early stages of language processing (such as phonetic processing), but the two languages may be using separate structures at later stages of processing (such as lexical processing).     

The contribution of linguistic factors to attribute inferences and semantic similarity judgements

Two studies are reported which examine the contribution of linguistic factors to attribute inferences and semantic similarity judgements. For this purpose a new method is developed which allows us to examine the contribution of language as a symbolically shared system. The two studies show that a substantial amount of the variance in both attribute inferences and semantic similarity judgements is mediated by socially shared linguistic conventions. The implications of these findings and the methodology for social cognition, and some models of personality and affect are discussed.     

Forming impressions from English and French first names: is there an in-group effect in Québec?

Using the Name Connotation Profile, English Canadian and French Canadian university students rated their impressions of people with English or French first names. Both the English and French students formed a more favorable impression of people who had names from their own linguistic group. These results are consistent with social identity theory, according to which people define themselves in part by groups to which they belong, with the contact hypothesis, according to which people feel more positively towards those with whom they have interacted more, and perhaps with the mere exposure effect, according to which liking for an object increases with the frequency with which it is presented.     

The effect of shared structure and content on reading nonwords: evidence for a CV skeleton

Four experiments examined the effect of shared skeletal structure versus content overlap on naming printed nonwords. Experiments 1-2 compared priming among nonwords sharing either skeletal structure and content (e.g., dus-DUS) or structure alone (e.g., pid-BAF) with controls that differed from the target in the number of skeleton slots (e.g., pid-BAF vs. plid-BAF). Conversely, in Experiments 3-4, same-versus different-structure primes contrasted only in the ordering of CV skeletal slots (e.g., fap-DUS vs. ift-DUS). Priming effects were modulated by shared content and skeletal similarity. The sensitivity of skeletal priming to the abstract arrangement of consonants and vowels suggests that skeletal representations assign distinct slots for consonants and vowels. Readers' sensitivity to skeletal structure in nonword identification indicates that assembled phonological representations are constrained by linguistic knowledge.     

A genetically informed study of the processes underlying the association between parental marital instability and offspring adjustment

Parental divorce is associated with problematic offspring adjustment, but the relation may be due to shared genetic or environmental factors. One way to test for these confounds is to study offspring of twins discordant for divorce. The current analyses used this design to separate the mechanisms responsible for the association between parental divorce, experienced either before or after the age of 16, and offspring well-being. The results were consistent with a causal role of divorce in earlier initiation of sexual intercourse and emotional difficulties, in addition to a greater probability of educational problems, depressed mood, and suicidal ideation. In contrast, the increased risk for cohabitation and earlier initiation of drug use was explained by selection factors, including genetic confounds. ((c) 2006 APA, all rights reserved).     

Structure and Content in Language Production: A Theory of Frame Constraints in Phonological Speech Errors

Theories of language production propose that utterances are constructed by a mechanism that separates linguistic content from linguistic structure, Linguistic content is retrieved from the mental lexicon, and is then inserted into slots in linguistic structures or frames. Support for this kind of model at the phonological level comes from patterns of phonological speech errors. W present an alternative account of these patterns using a connectionist or parallel distributed proceesing (PDP) model that learns to produce sequences of phonological features. The model's errors exhibit some of the properties of human speech errors, specifically, properties that have been attributed to the action of phonological rules, frames, or other structural generalizations.     

Ambiguity in the brain: what brain imaging reveals about the processing of syntactically ambiguous sentences

Two fMRI studies investigated the time course and amplitude of brain activity in language-related areas during the processing of syntactically ambiguous sentences. In Experiment 1, higher levels of activation were found during the reading of unpreferred syntactic structures as well as more complex structures. In Experiments 2A and 2B higher levels of brain activation were found for ambiguous sentences compared with unambiguous sentences matched for syntactic complexity, even when the ambiguities were resolved in favor of the preferred syntactic construction (despite the absence of this difference in previous reading time results). Although results can be reconciled with either serial or parallel models of sentence parsing, they arguably fit better into the parallel framework. Serial models can admittedly be made consistent but only by including a parallel component. The fMRI data indicate the involvement of a parallel component in syntactic parsing that might be either a selection mechanism or a construction of multiple parses.     

Reasoning versus text processing in the Wason selection task: A nondeontic perspective on perspective effects

We argue that perspective effects in the Wason four-card selection task are a product of the linguistic interpretation of the rule in the context of the problem text and not of the reasoning process underlying card selection. In three experiments, participants recalled the rule they used in either a selection or a plausibility rating task. The results showed that (1) participants tended to recall rules compatible with their card selection and not with the rule as stated in the problem and (2) recall was not affected by whether or not participants performed card selection. We conclude that perspective effects in the Wason selection task do not concern how card selection is reasoned about but instead reflect the inferential text processing involved in the comprehension of the problem text. Together with earlier research that showed selection performance in nondeontic contexts to be indistinguishable from selection performance in deontic contexts (Almor & Sloman, 1996; Sperber, Cara, & Girotto, 1995), the present results undermine the claim that reasoning in a deontic context elicits specialized cognitive processes.     

Coercion and pragmatic presuppositions

In Category Mistakes, Magidor proposes that sortal restrictions should be viewed as pragmatic presuppositions. This contrasts with recent linguistic theories of successfully resolved category mistakes, e.g. coercions or copredication. It has been argued that for the proper treatment of such examples, sortal restrictions should be expressed by semantic presuppositions since they need to interact with compositional semantics. I explore possible ways in which Magidor’s theory could be extended to explain examples of coercion and copredication. The outcome of the discussion is that incorporation of these facts into Magidor’s pragmatic system might be possible, but ecessitates choices that are far from trivial.     

Linguistic Convergence to Observed Versus Expected Behavior in an Alien-Language Map Task

Individuals shift their language to converge with interlocutors. Recent work has suggested that convergence can target not only observed but also expected linguistic behavior, cued by social information. However, it remains uncertain how expectations and observed behavior interact, particularly when they contradict each other. We investigated this using a cooperative map task experiment, in which pairs of participants communicated online by typing messages to each other in a miniature “alien” language that exhibited variation between alien species. The overall task comprised three phases, in each of which participants were told that they would be paired with a different partner. One member of the pair was given explicit linguistic expectations in each phase, while the software controlled whether or not observed behavior from their partner would be consistent or inconsistent with these expectations. The other participant was given no such expectations, allowing us to control for the role of expectation. Participants converged to both observed and expected linguistic behavior, and convergence was boosted when observation and expectation were aligned. When expected and observed behavior were misaligned, participants updated their expectations, though convergence levels did not drop. Furthermore, participants generalized what they learned about one partner to apparent novel partners of the same alien species. We also discuss individual variation in convergence patterns and the lack of a relationship between linguistic convergence and success at the map task. Findings are consistent with observations outside the laboratory that language users converge toward expected linguistic behavior. They also have broader implications for understanding linguistic accommodation and the influence of social information on linguistic processing and production.     

The illocutionary force of laws

This article provides a speech act analysis of ‘crime-enacting’ provisions in criminal statutes, focusing on the illocutionary force of these provisions. These provisions commonly set out not only particular crimes and their characteristics but also their associated penalties. Enactment of a statute brings into force new social facts, typically norms, through the official utterance of linguistic material. These norms are supposed to guide behaviour: they tell us what we must, may, or must not do. Our main claim is that the illocutionary force of such provisions is primarily ‘world-creating’, i.e. effective, or declarational, rather than directive (behaviour-guiding). We assume that directive illocutionary force is either direct or indirect, showing that provisions need not contain the linguistic items that make for direct directives and that according to standard tests no indirect directive is present. A potential counter-argument is that any utterance serving to direct behaviour is necessarily a directive. We show that this behaviour-directing property is shared by some clear non-directives.
