Communication constraints on the linguistic intergroup bias

We examined whether the linguistic intergroup bias (LIB) is a context-free, invariant process or influenced by communicative purpose. The reported experiment shows that biased language use (positive behaviors of a partner and negative behaviors of an opponent are described with abstract predicates, negative partner and positive opponent behaviors are described with concrete predicates) occurs only when the communication has a clear purpose, but not when it does not. The implications of communicative purpose as a constraint on the psychological processes driving the LIB are discussed as well as the possible impact of biased language use upon recipients.     

The role of linguistic labels in inductive generalization

What is the role of linguistic labels in inductive generalization? According to one approach labels denote categories and differ from object features, whereas according to another approach labels start out as features and may become category markers in the course of development. This issue was addressed in four experiments with 4- and 5-year-olds and adults. In Experiments 1 to 3, we replicated Yamauchi and Markman’s findings with adults (Journal of Memory and Language, 1998, Vol. 39, pp. 124–148, and Journal of Experimental Psychology: Learning, Memory, and Cognition, 2000, Vol. 26, pp. 776–795) and extended the paradigm to young children. In Experiment 4, we compared effects of labels with those of highly salient visual features. Overall, results of these experiments provide strong support for the idea that early in development labels function the same way as other features, but they may become category markers in the course of development. A related finding is that whereas categorization and induction may be different processes in adults, they seem to be equivalent in young children. These results are discussed with respect to theories of development of inductive generalization.     

The development of landmarks in spatial memory: the role of differential experience

To assess how differential experience with objects in a spatial array might serve to establish relative landmarks within the array, first and fifth graders learned models of a town and farm under two conditions. In a homogeneous condition, all elements in the array were visited an equal number of times. In a landmark condition, the relative landmark status of an element was established by distributing the same total number of visits unequally across the elements. The effects of such landmarks on spatial memory were assessed both in reconstructions of the entire array and by pairwise distance estimations. The landmark condition led to a general improvement in spatial recall accuracy as well as providing a relative landmark within the array to help organize the space. The results suggest that different levels of experience (controlling for overall experience and object salience) can establish elements as relative landmarks in spatial memory. Although there was clear developmental improvement in spatial memory, the specific landmark effects were similar for both first and fifth graders.     

The role of test procedure in linguistic integration studies

The effects of type of recognition test procedure were studied in a Bransford and Franks (1971) integration paradigm. Subjects received a two-alternative forced-choice recognition test or a modified “forced-choice” test in which all the sentences for each idea set were presented at once and the “old” sentences had to be identified. Contrary to the usual Bransford and Franks results, in which a yes-no, one-sentence-at-a-time recognition procedure is employed, the ability to discriminate “old” sentences from “new” sentences was clearly observed. A bias for selecting more complex sentences, however, was found for the modified “forced-choice” procedure. A prototype learning model is described to account for these results and previous data.     

The role of some definite references in linguistic integration

Definite reference increases thematic integration for semantically related sentences (DeVilliers, 1974). Therefore, definite reference should increase linguistic integration in the Bransford-Franks integrated recognition paradigm. Two recognition and two recall studies demonstrated that, if anything, indefinite reference increases linguistic integration effects, as measured by existing measures of integration. However, definite reference increases topical clustering in recall. Results cast doubt on the validity of existing measures of linguistic integration and indicate that the tally model of performance in integrated recognition tasks (Reitman & Bower, 1973) is not totally adequate, either. Results are compatible with the associative model of Anderson and Bower (1973). Topical clustering appears to be a better measure of integrated memory than are existing measures of linguistic integration. Retention of information about the propositional form in which semantically related sentences are presented and integrated memory are not necessarily incompatible.     

The role of the right hemisphere in the production of linguistic stress

Recent research has proposed a general prosodic disturbance associated with right hemisphere damage (RHD), one encompassing both affective and linguistic functions. The present study attempted to explore whether the ability to produce linguistic prosody was impaired in this patient population. Productions of phonemic stress tokens (e.g., Re'dcoat vs. red coa't) as well as examples of contrastive stress, or sentential emphasis (e.g., Sam hated the movie), were elicited from eight male speakers with unilateral right hemisphere CVAs and seven male control subjects. Two types of analyses were conducted on these utterances. Acoustic analysis focused on the correlates associated with word stress, namely changes in amplitude, duration, and fundamental frequency. The perceptual saliency of emerging cues to stress was also examined by presentation of test tokens to phonetically trained listeners for identification of stress placement. The patients as a group produced fewer acoustic cues to stress compared to the normal subjects, but no statistical differences were found between groups for either stress at the phrase level or at the sentence level. In the perceptual analysis, stress produced by the patient group was judged to be less salient than that for the normal group, although a high degree of variability was evident in both populations. The data suggest a spared processing mechanism for linguistic prosody in RHD speakers, thus mitigating against the view of a general dysprosody tied to RHD.     

The role of the input on the development of the LC bias: A crosslinguistic comparison

Previous studies have described the existence of a phonotactic bias called the Labial–Coronal (LC) bias, corresponding to a tendency to produce more words beginning with a labial consonant followed by a coronal consonant (i.e. “bat”) than the opposite CL pattern (i.e. “tap”). This bias has initially been interpreted in terms of articulatory constraints of the human speech production system. However, more recently, it has been suggested that this presumably language-general LC bias in production might be accompanied by LC and CL biases in perception, acquired in infancy on the basis of the properties of the linguistic input. The present study investigates the origins of these perceptual biases, testing infants learning Japanese, a language that has been claimed to possess more CL than LC sequences, and comparing them with infants learning French, a language showing a clear LC bias in its lexicon. First, a corpus analysis of Japanese IDS and ADS revealed the existence of an overall LC bias, except for plosive sequences in ADS, which show a CL bias across counts. Second, speech preference experiments showed a perceptual preference for CL over LC plosive sequences (all recorded by a Japanese speaker) in 13- but not in 7- and 10-month-old Japanese-learning infants (Experiment 1), while revealing the emergence of an LC preference between 7 and 10 months in French-learning infants, using the exact same stimuli. These crosslinguistic behavioral differences, obtained with the same stimuli, thus reflect differences in processing in two populations of infants, which can be linked to differences in the properties of the lexicons of their respective native languages. These findings establish that the emergence of a CL/LC bias is related to exposure to a linguistic input.     

The role of the right hemisphere in the apprehension of complex linguistic materials

To secure information on which aspects of linguistic functioning might be mediated by the nondominant hemisphere, a test battery assessing sensitivity to narrational and humorous materials was administered to a population of right-hemisphere-damaged patients, as well as relevant control groups of normal, aging, and aphasic individuals. While elementary linguistic functioning was adequate, the right-hemisphere-injured groups exhibited consistent difficulties in respecting the boundaries of a fictive entity, assessing the plausibility of elements within a story or joke, selecting the appropriate punch line for a joke, and integrating elements of a story into a coherent narrative. Certain elements—specifically emotional content and noncanonical facts injected into a narrative—also posed characteristic difficulties for these patients. The results suggest that, in contrast to the other populations, right-hemisphere patients exhibit special difficulties in processing complex linguistic entities and in utilizing the surrounding context as they assess linguistic messages.     

The role of memory consolidation in generalisation of new linguistic information

Accounts of memory that postulate complementary learning systems (CLS) have become increasingly influential in the field of language learning. These accounts predict that generalisation of newly learnt linguistic information to untrained contexts requires offline memory consolidation. Such generalisation should not be observed immediately after training, as these accounts claim unconsolidated representations are context and hippocampus-dependent and gain contextual and hippocampal independence only after consolidation. We trained participants on new affixes (e.g., -nule) attached to familiar word stems (e.g., buildnule), testing them immediately or 2days later. Participants showed an immediate advantage for trained affixes in a speeded shadowing task as long as these affixes occurred in the stem contexts in which they were learnt (e.g., buildnule). This learning effect generalised to words with untrained stems (e.g., sailnule) only in the delayed test condition. By contrast, a non-speeded definition selection task showed immediate generalisation. We propose that generalisation can be supported by initial context-dependent memories given sufficient processing time, but that context-independent lexical representations emerge only following consolidation, as predicted by CLS accounts.     

Perception of movement in American Sign Language: Effects of linguistic structure and linguistic experience

In order to reveal the psychological representation of movement from American Sign Language (ASL), deaf native signers and hearing subjects unfamiliar with sign were asked to make triadic comparisons of movements that had been isolated from lexical and from grammatically inflected signs. An analysis of the similarity judgments revealed a small set of physically specifiable dimensions that accounted for most of the variance. The dimensions underlying the perception of lexical movement were in general different from those underlying inflectional movement, for both groups of subjects. Most strikingly, deaf and hearing subjects significantly differed in their patterns of dimensional salience for movements, both at the lexical and at the inflectional levels. Linguistically relevant dimensions were of increased salience to native signers. The difference in perception of linguistic movement by native signers and by naive observers demonstrates that modification of natural perceptual categories after language acquisition is not bound to a particular transmission modality, but rather can be a more general consequence of acquiring a formal linguistic system.     

The causal role of interpretive bias in anxiety reactivity

Elevated anxiety vulnerability is associated with a tendency to interpret ambiguous stimuli as threatening, but the causal basis of this relationship has not been established. Recently, procedures have been developed to systematically manipulate interpretive bias, but the impact of such manipulation on anxiety reactivity to a subsequent stressor has not yet been examined. In the present study, training procedures were used to induce interpretive biases favoring the threatening or nonthreatening meanings of ambiguous information in a sample of 48 undergraduate students. Following this interpretive training, participants' emotional reactions to a stressful video were assessed. The finding that the manipulation of interpretive bias modified emotional reactivity supports the hypothesis that interpretive bias can indeed play a causal role in anxiety vulnerability.     

The role of egocentrism and focalism in the emotion intensity bias

People sometimes judge their emotions, preferences, and attitudes to be more intense than those of other people. Two experiments tested whether this emotion intensity bias in direct comparisons results from two non-motivated cognitive processes—egocentrism and focalism. In Study 1, the intensity bias was found even when comparing a friend’s preferences to peers. In Study 2, attention given to own versus other’s preferences, and the referent of the comparison (self or others) were manipulated. Results indicated that attention to others reduced the bias, presumably by reducing egocentrism. Consistent with focalism, the bias also emerged when a friend was the target of comparison, and the bias was eliminated when the self was the referent rather than the target of comparison. In the discussion, we evaluate these accounts in light of some alternative explanations for the intensity bias.     

The role of attachment in the post-divorce experience

The loss of the spouse resulting from marital breakdown appears to be a central component of post-divorce distress. However, comparatively little empirical research has examined the nature of this broken bond or its impact on the divorced adult. This study tests the hypothesis that the continuing positive feelings for the ex-spouse following divorce are very salient for the individual and are related to increased distress. Sixty recently divorced women selected from court records were randomly assigned to one of three conditions in which they recalled the ex-spouse in a positive, loving interaction (PS); the ex-spouse in a conflictual interaction (C); or a friend in a positive, loving interaction (PS). A post-recall thought sampling procedure was employed to measure the frequency of thoughts about the ex-spouse. The subjects in the PS condition had significantly more post-recall thoughts of the ex-spouse and significantly more thoughts about coping than those in either the C or the PF conditions. The implications of these data for theories of post-divorce adaptation and adult attachment are discussed.     

The word and us: Implications of linguistic design for subjective experience and for the experience of subjectivity

As language evolved in the history of civilization, a verbal form of communication became not only possible but prevalent. Inherent in the linguistic communication system is symbolization, the representation, by means of words, of what exists or occurs.The subject addressed in the present work involves the implications of the linguistic symbol system, first, for the subjective experiences of emotion and consciousness, and second, for the experience of subjectivity, that is, the experience of being somebody psychologically. Further considerations are those regarding solutions to the psychological consequences of verbal symbolization.In the process of sorting out issues and avenues of approach to the subjects mentioned, the thought occurred that I and myself and me were taking a journey into the field of language, in order to find out whatthe word might mean forus. This thought is reflected in the main title of this paper.Francina Middelman, M.D., is a retired (September 1984) psychiatrist. She received her medical education at the University of Amsterdam, The Netherlands, and her psychiatric training in the Department of Psychiatry, College of Medicine, University of Cincinnati. Her last position was that of medical director, Athens Mental Health Center, Athens, Ohio.     

The role of target information on manual-aiming bias

Three experiments were conducted to examine the role of target information in manual aiming. The key manipulations in this experiment were the use of two target contexts (the two forms of the Müller-Lyer illusion) and the visual conditions under which subjects moved. In Experiment 1, we demonstrated that the inward- and outward-pointing arrows biased manual-aiming movements in a manner consistent with their well-known influence on perceptual judgements. The elimination of visual feedback during the aiming movement (Experiment 2), and visual information about the target-aiming layout prior to the movement (Experiment 3) increased the magnitude of the bias. Together, these results demonstrate the strong effect of target information on manual aiming, and specifically, on the movement-planning processes that precede movement.     

The influence of linguistic experience on the cognitive processing of pitch in speech and nonspeech sounds

In the present experiment, the authors tested Mandarin and English listeners on a range of auditory tasks to investigate whether long-term linguistic experience influences the cognitive processing of nonspeech sounds. As expected, Mandarin listeners identified Mandarin tones significantly more accurately than English listeners; however, performance did not differ across the listener groups on a pitch discrimination task requiring fine-grained discrimination of simple nonspeech sounds. The crucial finding was that cross-language differences emerged on a nonspeech pitch contour identification task: The Mandarin listeners more often misidentified flat and falling pitch contours than the English listeners in a manner that could be related to specific features of the sound structure of Mandarin, which suggests that the effect of linguistic experience extends to nonspeech processing under certain stimulus and task conditions.
