The place of words and numbers in psychiatric research

In recent decades, there has been widespread debate in the human and social sciences regarding the compatibility and the relative merits of quantitative and qualitative approaches in research. In psychiatry, depending on disciplines and traditions, objects of study can be represented either in words or using two types of mathematization. In the latter case, the use of mathematics in psychiatry is most often only local, as opposed to global as in the case of classical mechanics. Relationships between these objects of study can in turn be explored in three different ways: 1/ by a hermeneutic process, 2/ using statistics, the most frequent method in psychiatric research today, 3/ using equations, i.e. using mathematical relationships that are formal and deterministic. The 3 ways of representing entities (with language, locally with mathematics or globally with mathematics) and the 3 ways of expressing the relationships between entities (using hermeneutics, statistics or equations) can be combined in a cross-tabulation, and nearly all nine combinations can be described using examples. A typology of this nature may be useful in assessing which epistemological perspectives are currently dominant in a constantly evolving field such as psychiatry, and which other perspectives still need to be developed. It also contributes to undermining the overly simplistic and counterproductive beliefs that accompany the assumption of a Manichean “quantitative/qualitative” dichotomy. Systematic examination of this set of typologies could be useful in indicating new directions for future research beyond the quantitative/qualitative divide.     

Brain reflections of words and their meaning

The neurobiological organization of meaningful language units, morphemes and words, has been illuminated by recent metabolic and neurophysiological imaging studies. When humans process words from different categories, sets of cortical areas become active differentially. The meaning of a word, more precisely aspects of its reference, may be crucial for determining which set of cortical areas is involved in its processing. Word-related neuron webs with specific cortical distributions might underlie the observed category-specific differences in brain activity. Neuroscientific principles can explain these differential topographies.     

Understanding the meaning of words and sentences: The role of non-linguistic processes

This special issue on linguistic and non-linguistic processes in the comprehending of words and sentences represents the outcome of a three-day workshop at the University of Tübingen, Germany. The workshop focused on the contribution of non-linguistic processes in language comprehension and hence brought together researchers from the domains of linguistic and non-linguistic cognition.     

The emergence of words: attentional learning in form and meaning

Children improve at word learning during the 2nd year of life—sometimes dramatically. This fact has suggested a change in mechanism, from associative learning to a more referential form of learning. This article presents an associative exemplar-based model that accounts for the improvement without a change in mechanism. It provides a unified account of children's growing abilities to (a) learn a new word given only 1 or a few training trials ("fast mapping"); (b) acquire words that differ only slightly in phonological form; (c) generalize word meanings preferentially along particular dimensions, such as object shape (the "shape bias"); and (d) learn 2nd labels for already-named objects, despite a persisting resistance to doing so ("mutual exclusivity"). The model explains these improvements in terms of increased attention to relevant aspects of form and meaning, which reduces memory interference. The interaction of associations and reference in word learning is discussed.     

A mismatch of meaning and intentionality between analyst and analysand

In this paper, I will consider a type of misunderstanding in the analytical dialogue and the possible unconscious motivations underlying this. I will also make reference to the patient's use of the analyst's words for the purpose of narcissistic enactment and will explore the extent of the analyst's involvement in this. The subjects of misunderstanding and narcissistic enactment will be dealt with in relation to a patient's way of processing certain interpretations at the beginning of analysis and the concealment of her way of processing the analyst's words. By contributing dreams and other significant material in the sessions, the patient gradually revealed her phantasies which enabled the analyst to uncover the possible factors which determined her particular attribution of meaning to the analyst's words and her retention of information about how she had initially construed his interpretations.     

Frequency of meaning use for ambiguous and unambiguous words

When using verbal stimuli, researchers usually equate words on frequency of use. However, for some ambiguous words (e.g.,ball as a round object or a formal dance), frequency counts fail to distinguish how often a particular meaning is used. This study evaluates the use of ratings to estimate meaning frequency. Analyses show that ratings correlate highly with word frequency counts when orthographic and meaning frequencies should converge, are not unduly influenced by semantic factors, and may provide a better measure of relative meaning dominance than the word association task does. Furthermore, the ratings allow researchers to equate or manipulate frequency of meaning use for ambiguous and unambiguous words. Ratings for 211 words are reported.     

The monolingual nature of speech segmentation by bilinguals.

Monolingual French speakers employ a syllable-based procedure in speech segmentation; monolingual English speakers use a stress-based segmentation procedure and do not use the syllable-based procedure. In the present study French-English bilinguals participated in segmentation experiments with English and French materials. Their results as a group did not simply mimic the performance of English monolinguals with English language materials and of French monolinguals with French language materials. Instead, the bilinguals formed two groups, defined by forced choice of a dominant language. Only the French-dominant groups showed syllabic segmentation and only with French language materials. The English-dominant group showed no syllabic segmentation in either language. However, the English-dominant group showed stress-based segmentation with English language materials; the French-dominant group did not. We argue that rhythmically based segmentation procedures are mutually exclusive, as a consequence of which speech segmentation by bilinguals is, in one respect at least, functionally monolingual.     

Effects of achievement contexts on the meaning structure of emotion words

Little is known about the impact of context on the meaning of emotion words. In the present study, we used a semantic profiling instrument (GRID) to investigate features representing five emotion components (appraisal, bodily reaction, expression, action tendencies, and feeling) of 11 emotion words in situational contexts involving success or failure. We compared these to the data from an earlier study in which participants evaluated the typicality of features out of context. Profile analyses identified features for which typicality changed as a function of context for all emotion words, except contentment, with appraisal features being most frequently affected. Those context effects occurred for both hypothesised basic and non-basic emotion words. Moreover, both data sets revealed a four-dimensional structure. The four dimensions were largely similar (valence, power, arousal, and novelty). The results suggest that context may not change the underlying dimensionality but affects facets of the meaning of emotion words.     

Limitations of the dual-process-theory regarding the writing of words and non-words to dictation

It is generally assumed that the lexical and phonological systems are involved in writing to dictation. In an experiment concerned with the writing of words and non-words to dictation, the handwriting of female students was registered using a digitising tablet. The data contradict the assumption that the phonological system represents an alexical process. Both words and non-words which were acoustically presented to the subjects were lexically parsed. The analysis of kinematic data revealed significant differences between the subjects' writing of words and non-words. The findings reveal gross disturbances of handwriting fluency during the writing of non-words. The findings of the experiment cannot be explained by the dual-process-theory.     

The influence of emotional meaning on the recall of words processed for form or self-reference

Summary How much does the recall of affectively positive, negative, and neutral words that differ in their emotional impact depend on the conceptual processing of these words? To answer this question one group of subjects were requested to rate the pronounceability of these words (formal orienting task), but were later tested for recall. Subsequently, they were asked to judge the intensity of the emotions aroused by the words. Another group of subjects received the latter, self-related task prior to the first exposure to the words. In both conditions the highly affect-arousing words were better recalled than the less emotional words. The affectively positive words were particularly well recalled, but only by those subjects involved in the formal orienting task. It is concluded that words are evaluated for their emotional content at an early stage of information processing as defined by Craik and Lockhart (1972).Extended version of an earlier paper delivered at the 34.

Eye movements during the reading of compound words and the influence of lexeme meaning

We examined the use of lexeme meaning during the processing of spatially unified bilexemic compound words by manipulating both the location and the word frequency of the lexeme that primarily defined the meaning of a compound (i.e., the dominant lexeme). The semantically dominant and nondominant lexemes occupied either the beginning or the ending compound word location, and the beginning and ending lexemes could be either high- or low-frequency words. Three tasks were used--lexical decision, naming, and sentence reading--all of which focused on the effects of lexeme frequency as a function of lexeme dominance. The results revealed a larger word frequency effect for the dominant lexeme in all three tasks. Eye movements during sentence reading further revealed larger word frequency effects for the dominant lexeme via several oculomotor motor measures, including the duration of the first fixation on a compound word. These findings favor theoretical conceptions in which the use of lexeme meaning is an integral part of the compound recognition process.     

Mirror reading of words and numbers: Practice and transfer effects

It remains unknown whether mirror reading represents a genuine text processing skill or is based on recognition of visual patterns. The present study attempts to determine whether (1) systematic practice with a particular mirrored typography also improves reading performance for other mirrored typographies, and whether (2) this transfer extends from lexical to numerical material and vice versa. The results show that short-term intensive practice with mirror-reversed words significantly improves reading performance not only for the trained typography but also for other mirrored typographies and mirror-reversed Arabic digits. Practice with mirror-reversed Arabic digits showed a mixed pattern of transfer effects with regard to other digit transformations and there were no transfer effects to lexical material. Hence, for lexical material, at least, improvement after training seems to be based on generalized skill with transfer effects beyond lexical material, rather than on mere improvement of visual recognition of the material used in training.     

Imagery, concreteness, and meaningfulness as determiners of the emotionality of words when meaning is controlled.

We studied variables that influenced rated emotionality value of words and the contribution of each one. 218 subjects rated each word in a list of 98 pairs of words (196 words), one concrete word and one abstract word in each pair, on imagery, concreteness, meaningfulness, and emotionality. Date of entry of each word into Spanish and word length were also examined. Stepwise multiple regression procedures were performed to evaluate the contribution made by each variable to over-all emotionality values. 39.06% of the emotionality variance was explained by imagery. Concreteness and meaningfulness values contributed 3.62% and 2.82%, respectively. Word length and date of entry were rejected in the final equation, as their contributions were minimal.     

Reading habits for both words and numbers contribute to the SNARC effect

This study compared the spatial representation of numbers in three groups of adults: Canadians, who read both English words and Arabic numbers from left to right; Palestinians, who read Arabic words and Arabic-Indic numbers from right to left; and Israelis, who read Hebrew words from right to left but Arabic numbers from left to right. Canadians associated small numbers with left and large numbers with right space (the SNARC effect), Palestinians showed the reverse association, and Israelis had no reliable spatial association for numbers. These results suggest that reading habits for both words and numbers contribute to the spatial representation of numbers.
