Sense and sensibility: dual routes from ethical leadership to moral voice

PurposeEthical leadership has been recognized as a critical factor in encouraging employees’ moral voices. This study offers a dual-route model to understand this process. The boundary conditions of these two routes are discussed herein.Design/methodology/approachThe data originate from a multiwave, multisource survey study of 212 leader–subordinate dyads in Taiwan drawn from a variety of industry sectors.FindingsThe findings validate both the cognitive (moral efficacy) and affective (affective attachment) pathways from ethical leadership to moral voice, influenced by the organizational factor of political climate. While the moral efficacy pathway is more pronounced in a situation of weak political climate, the affective attachment pathway remains effective regardless of the climate’s strength.Practical implicationsManagers need to identify if their organization prioritizes rational professionalism or interpersonal affection. In the former case, they should focus on the learning effects of ethical leadership. Conversely, in the latter, the emphasis should be on the leader-subordinate relationship. Doing so optimizes the effectiveness of ethical leadership in growing moral voices.Originality/valueConsidering both cognitive and affective routes from ethical leadership to moral voice could integrate social learning theory (SLT) and social exchange theory (SET). Identifying factors influencing these two routes resonates with the leader–situation interaction perspective. This research deepens the understanding of ethical leadership's effects on encouraging and protecting employee moral voice.

The time course of the spatial representation of 'past' and 'future' concepts: New evidence from the STEARC effect.

Humans use space to think of and communicate the flow of time. This spatial representation of time is influenced by cultural habits so that in left-to-right reading cultures, short durations and past events are mentally positioned to the left of long durations and future events. The STEARC effect (Space Temporal Association of Response Codes) shows a faster classification of short durations/past events with responses on the left side of space and of long durations/future events with responses on the right side. We have recently showed that during the classification of time durations, space is a late heuristic of time because in this case, the STEARC appears only when manual responses are slow, not when they are fast. Here, we wished to extend this observation to the semantic classification of words as referring to the 'past' or the 'future'. We hypothesised that the semantic processing of 'past' and 'future' concepts would have engaged slower decision processes than the classification of short versus long time durations. According to dual-route models of conflict tasks, if the task-dependent classification/decision process were to proceed relatively slowly, then the effects of direct activation of culturally preferred links between stimulus and response (S-R), i.e., past/left and future/right in the case of the present task, should attain higher amplitudes before the instruction-dependent correct response is selected. This would imply that, at variance with the faster classification of time durations, during the slower semantic classification of time concepts, in incongruent trials, the direct activation of culturally preferred S-R links should introduce significant reaction time (RT) costs and a corresponding STEARC at the fastest manual responses in the experiment too. The study's results confirmed this hypothesis and showed that in the classification of temporal words, the STEARC also increased as a function of the length of RTs. Taken together, the results from sensory duration and semantic classification STEARC tasks show that the occurrence, strength and time course of the STEARC varies significantly as a function of the speed and level of cognitive processing required in the task.

The impact of Diglossia-Effect on Reading Acquisition Among Arabic-Speaking Children: A Longitudinal Study.

Arabic is a diglossic language, where two language varieties are used: spoken Arabic (SpA) and standard Arabic (StA). The words may be "identical" (maintaining the same phonological expression in the SpA and StA) or "unique" to StA). This study examined the effect of diglossia on reading according to the lexical distance between the SpA and StA forms and whether this influence changes with age. The participants were 137 first-graders that were followed to the second grade. The findings indicated a significant effect of grade level with higher performance in the second grade. A significant association was obtained between the lexical distance and reading accuracy and rate with better performance for identical than unique items across grade levels. No significant interaction between lexical distance and grade level was found. The results indicate the contribution of reading unique and identical forms in the first grade to reading in the second grade. The advantage in reading identical among unique words is discussed in light of the lexical quality hypothesis and dual-route model. The implications of these results were discussed in the context of diglossia, especially the need for StA oral language enrichment at the preschool level.

Word Reading and Spelling Processing and Acquired Dyslexia post Unilateral Stroke.

This study investigates the performance of adults with cerebrovascular lesion in the right hemisphere (RHL) or left hemisphere (LHL) in word reading (TLPP) and spelling (TEPP) tasks based on the dual-route models. A total of 85 adults were assessed, divided into three groups: 10 with RHL, 15 with LHL, and 60 neurologically healthy ones. The performance of the three groups was compared in terms of the characteristics of the words (regularity, frequency, and length) and pseudowords (length), error types, and psycholinguistic effects. A cluster analysis was performed to investigate the profiles of the reading. The LHL group showed lower scores in reading and spelling tasks of words and pseudowords, as well as a higher frequency of errors. Four LHL cases were found to have an acquired dyslexia profile. This study highlights that the tasks developed in Brazil are in accordance with theoretical models of written language, and the results point to the heterogeneous performance of the cases with acquired dyslexia.

The lexical processing of Japanese collocations by Chinese Japanese-as-a-Foreign-Language learners: An experimental study by manipulating the presentation modality, semantic transparency, and translational congruency.

Research on collocations has become an essential issue in L2 acquisition and cognitive psychology. Previous studies have mainly focused on phonographic languages such as English, Swedish, and German, and primarily discussed the effect of semantic transparency and translational congruency. However, these studies have lacked (1) an analysis of the interactions between presentation modalities (visual vs. auditory) and the semantic transparency and translational congruency, and (2) a discussion of an ideographic language, such as Chinese and Japanese. We conducted an experiment with 36 Chinese Japanese-as-a-Foreign-Language learners to examine the processing of Japanese collocations. In the experiment, we manipulated the presentation modality, semantic transparency, and translational congruency during a lexical judgment task. Data analysis using linear mixed-effects models revealed the following. (1) In both conditions of semantic transparency and translational congruency, the auditory presentation was associated with longer reaction times than the visual presentation. (2) In the visual presentation condition, neither semantic transparency nor translational congruency showed significant effects. (3) In the auditory presentation condition, the reaction time for collocations with high semantic transparency tended to be longer than that for collocations with medium semantic transparency and significantly longer than that for collocations with low semantic transparency. The reaction time for collocations with congruent translation was longer than that for collocations with incongruent translation. These results support the dual-route model of Japanese collocational processing by Chinese Japanese-as-a-Foreign-Language learners. Our findings suggest that whether the analytic or holistic processing dominates is closely related to the learners' knowledge of Chinese and Japanese Kanji words and strongly influenced by the presentation modality, semantic transparency, and translational congruency.

Shared and distinct routes in speech and gesture imitation: Evidence from stroke

Dual-route models of high-level (praxis) actions distinguish between an “indirect” semantic route mediating meaningful gesture imitation, and a “direct” sensory-motor route mediates meaningless gesture imitation. Similarly, dual-route language models distinguish between an indirect route mediating production and repetition of words, and a direct route mediating non-word repetition. Although aphasia and limb apraxia frequently co-occur following left-hemisphere cerebrovascular accident (LCVA), it is unclear which aspects of these functional-neuroanatomic dual-route architectures are shared across praxis and language domains. This study focused on gesture imitation to test the hypothesis that semantic information (and portions of the indirect route) are shared across domains, whereas two distinct dorsal routes mediate sensory-motor mapping. Forty chronic LCVA and 17 neurotypical controls completed semantic memory and language tasks and imitated 3 types of gesture stimuli: (1) labeled/“named” meaningful, (2) unnamed meaningful, and (3) meaningless gestures. The comparison of accuracy between meaningless versus unnamed meaningful gestures examined the benefits of semantic information, while the comparison of unnamed meaningful versus named meaningful imitation examined additional benefits of linguistic cueing. Mixed-effects models examined group by task interaction effects on gesture ability. We found that for patients with LCVA, unnamed meaningful gestures were imitated more accurately than meaningless gestures, suggesting that semantic information was beneficial, but there was no benefit of labeling. Reduced benefit of semantic information on gesture accuracy was associated with lesions to inferior frontal and posterior temporal regions as well as semantic memory performance on a pictorial (non-gesture) task. In contrast, there was no relationship between meaningless gesture imitation and nonword repetition, indicating that measures of direct route performance are not associated across language and action. These results provide preliminary evidence that portions of the indirect semantic route are shared across the language and action domains, while two direct sensory-motor mapping routes mediate word repetition and gesture imitation.

Full-form vs. combinatorial processing of Chinese compound words: Evidence from mismatch negativity

This study examined whether Chinese spoken compound words are processed via full-form access or combination through morphemes by recording mismatch negativity (MMN). MMN has been shown to be larger for linguistic units that involves full-form access (lexical MMN enhancement) and smaller for separate but combinable units (combinatorial MMN reduction). Chinse compound words were compared against pseudocompounds, which do not have full-form representations in the long-term memory and are “illegal” combinations. All stimuli were disyllabic (bimorphemic). Word frequency was manipulated with the prediction that low-frequency compounds are more likely processed combinatorially, while high-frequency ones are more likely accessed in full forms. The results showed that low-frequency words elicited smaller MMNs than pseudocompounds, which supported the prediction of combinatorial processing. However, neither MMN enhancement nor reduction was found for high-frequency words. These results were interpreted within the dual-route model framework that assumes simultaneous access to words and morphemes.

Probing the Dual-Route Model of the SNARC Effect by Orthogonalizing Processing Speed and Depth.

The dual-route model explains the SNARC (Spatial-Numerical Association of Response Codes) effect assuming two routes of parallel information processing: the unconditional route (automatic activation of pre-existing links) and the conditional route (activation of task-specific links). To test predictions derived from this model, we evaluated whether response latency in superficial number processing modulates the SNARC effect in a color task (participants judged the color of a number). In Experiment 1, participants performed a parity task, an easy color task (short RTs), and a difficult color task (RTs similar to those of the parity task). A SNARC effect emerged only in the parity task. In Experiment 2, participants performed a color task and a secondary task under four conditions chosen to orthogonally manipulate response latency (short vs. long) and processing depth (semantic vs. perceptual). Only the long-latency perceptual-processing condition elicited a SNARC effect. To explain these results, we suggest that the cognitive resources required by a secondary task might dilute the SNARC effect. Our results indicate that the dual-route model should be modified to take into account additional factors (e.g., working memory load) that influence the level of activation of the unconditional route.

How does digital technology innovation enhance firm value? A dual route model

Differs to digital innovation, which is application-oriented of digital technologies, digital technology innovation focuses on developing and creating new digital technologies (creation-oriented). Thus, digital technology innovation forms the foundation of digital innovation. Increasingly, firms, especially those in manufacturing, are recognizing the crucial role of digital technology innovation in shaping their intangible value. In order to determine whether digital technology innovation can enhance firm value and the specific mechanism involved, this study draws on patent data (the fields of digital technology are defined based on IPC) and annual report data of listed manufacturing firms in China to reveal the specific relationship between digital technology innovation and the enhancement of firm value. We find that that digital technology innovation can make a significant contribution to firm value; more important, the relationships between digital technology innovation and lowering costs, upgrading efficiency can be characterized as an inverted U-shaped pattern and a Ushaped pattern, respectively. These results hold after the several robustness checks. Additional analyses show that these relationships differ significantly across types of state ownership, firm size, and location feature. Finally, our mechanism analysis suggests that lowering costs and upgrading efficiency driven by digital technology innovation is a key component of the value-enhancing effect.

Behavioral Signatures of Memory Resources for Language: Looking beyond the Lexicon/Grammar Divide.

Although there is a broad consensus that both the procedural and declarative memory systems play a crucial role in language learning, use, and knowledge, the mapping between linguistic types and memory structures remains underspecified: by default, a dual-route mapping of language systems to memory systems is assumed, with declarative memory handling idiosyncratic lexical knowledge and procedural memory handling rule-governed knowledge of grammar. We experimentally contrast the processing of morphology (case and aspect), syntax (subordination), and lexical semantics (collocations) in a healthy L1 population of Polish, a language rich in form distinctions. We study the processing of these four types under two conditions: a single task condition in which the grammaticality of stimuli was judged and a concurrent task condition in which grammaticality judgments were combined with a digit span task. Dividing attention impedes access to declarative memory while leaving procedural memory unaffected and hence constitutes a test that dissociates which types of linguistic information each long-term memory construct subserves. Our findings confirm the existence of a distinction between lexicon and grammar as a generative, dual-route model would predict, but the distinction is graded, as usage-based models assume: the hypothesized grammar-lexicon opposition appears as a continuum on which grammatical phenomena can be placed as being more or less "ruly" or "idiosyncratic." However, usage-based models, too, need adjusting as not all types of linguistic knowledge are proceduralized to the same extent. This move away from a simple dichotomy fundamentally changes how we think about memory for language, and hence how we design and interpret behavioral and neuroimaging studies that probe into the nature of language cognition.

The role of cognitive control in the SNARC effect: A review.

The spatial-numerical association of response codes (SNARC) effect, in which people respond to small numbers faster with the left hand and to large numbers faster with the right hand, is a popular topic in cognitive psychology. Some well-known theoretical accounts explaining this effect include the mental number line model, polarity correspondence principle, dual-route model, and working memory account. However, these fail to explain the finding that the size of the SNARC effect is modulated by cognitive control. Here, we propose a new account-a cognitive control-based view of the SNARC effect. This view argues that the SNARC effect is fundamentally determined by cognitive control in resolving conflicts during stimulus-response mapping. Several subcomponents of cognitive control, such as working memory, mental or task set shifting, inhibition control, and conflict adaptation, can easily modulate the SNARC effect. The cognitive control-based view can account for the flexible SNARC effect observed in diverse task situations while providing new insight into its mechanism.

The predictive function of Swedish word accents.

Swedish lexical word accents have been repeatedly said to have a low functional load. Even so, the language has kept these tones ever since they emerged probably over a thousand years ago. This article proposes that the primary function of word accents is for listeners to be able to predict upcoming morphological structures and narrow down the lexical competition rather than being lexically distinctive. Psycho- and neurophysiological evidence for the predictive function of word accents is discussed. A novel analysis displays that word accents have a facilitative role in word processing. Specifically, a correlation is revealed between how much incorrect word accents hinder listeners’ processing and how much they reduce response times when correct. Finally, a dual-route model of the predictive use of word accents with distinct neural substrates is put forth.

Morphology Within the Parallel Architecture Framework

          The Parallel Architecture (PA) framework (Jackendoff 2002, 2007, Culicover & Jackendoff 2005) is one of the most complete constraint-based linguistic theories that encompasses phonology, syntax and semantics. However, it lacks a fully developed model of word formation. More recently, a theory called Relational Morphology (RM) (Jackendoff & Audring 2020) has been developed, that integrates into the PA. The current study shows how the Slot Structure model (Benavides 2003, 2009, 2010), which is compatible with the PA and is based on the dual-route model and percolation of features (Pinker 1999, 2006; Huang & Pinker 2010), can provide a better account of morphology than RM, and can also be incorporated into the PA, thus contributing to make this a more explanatory framework. Spanish data are used as the basis to demonstrate the implementation of the SSM. The current paper demonstrates two key problems for RM: inconsistent and confusing coindexation, and a proliferation of schemas, and shows that these issues do not arise in the Slot Structure model. Overall, the paper points out significant drawbacks in the RM framework, while at the same time showing how the PA’s morphological component can be enriched with the Slot Structure model.

Frequency Effects on Spelling Error Recognition: An ERP Study.

Spelling errors are ubiquitous in all writing systems. Most studies exploring spelling errors focused on the phonological plausibility of errors. However, unlike typical pseudohomophones, spelling errors occur in naturally produced written language. We investigated the time course of recognition of the most frequent orthographic errors in Russian (error in an unstressed vowel in the root) and the effect of word frequency on this process. During event-related potentials (ERP) recording, 26 native Russian speakers silently read high-frequency correctly spelled words, low-frequency correctly spelled words, high-frequency words with errors, and low-frequency words with errors. The amplitude of P200 was more positive for correctly spelled words than for misspelled words and did not depend on the frequency of the words. In addition, in the 350–500-ms time window, we found a more negative response for misspelled words than for correctly spelled words in parietal–temporal-occipital regions regardless of word frequency. Considering our results in the context of a dual-route model, we concluded that recognizing misspelled high-frequency and low-frequency words involves common orthographic and phonological processes associated with P200 and N400 components such as whole word orthography processing and activation of phonological representations correspondingly. However, at the 500–700 ms stage (associated with lexical-semantic access in our study), error recognition depends on the word frequency. One possible explanation for these differences could be that at the 500–700 ms stage recognition of high-frequency misspelled and correctly spelled words shifts from phonological to orthographic processes, while low-frequency misspelled words are accompanied by more prolonged phonological activation. We believe these processes may be associated with different ERP components P300 and N400, reflecting a temporal overlap between categorization processes based on orthographic properties for high-frequency words and phonological processes for low-frequency words. Therefore, our results complement existing reading models and demonstrate that the neuronal underpinnings of spelling error recognition during reading may depend on word frequency.

Using electrophysiological correlates of early semantic priming to test models of reading aloud

The speed at which semantics is accessed by words with consistent (simple) and inconsistent (difficult) spelling–sound correspondences can be used to test predictions of models of reading aloud. Dual-route models that use a word-form lexicon predict consistent words may access semantics before inconsistent words. The Triangle model, alternatively, uses only a semantic system and no lexicons. It predicts inconsistent words may access semantics before consistent words, at least for some readers. We tested this by examining event-related potentials in a semantic priming task using consistent and inconsistent target words with either unrelated/related or unrelated/nonword primes. The unrelated/related primes elicited an early effect of priming on the N1 with consistent words. This result supports dual-route models but not the Triangle model. Correlations between the size of early priming effects between the two prime groups with inconsistent words were also very weak, suggesting early semantic effects with inconsistent words were not predictable by individual differences. Alternatively, there was a moderate strength correlation between the size of the priming effect with consistent and inconsistent words in the related/unrelated prime group on the N400. This offers a possible locus of individual differences in semantic processing that has not been previously reported.

Cognitive development of imitation of intransitive gestures: an analysis of hand and finger errors

ABSTRACT The dual-route model proposes that imitation of meaningful gestures relies on a lexical route whereas imitation of meaningless gestures relies on a sub-lexical route. The aim of the present study was to investigate the development of imitation of intransitive meaningful and meaningless gestures in children from 6 to 9 years old by exploring hand and finger errors. Despite lower performance, children showed similar patterns than adults with better imitation of meaningful compared to meaningless gestures. Concerning body part errors, children made more errors than adults. Moreover, children produced more hand errors than adults for meaningful gestures whereas they were no difference for meaningless gestures. These results suggest that the two routes are present but are still maturing. Moreover, several specific and non-specific factors may have impacted imitation skills. Further studies are needed to disentangle the role of these factors in imitation of intransitive gestures during development from childhood to adulthood.

The Semantic and Phonological Priming in Written Chinese Word Recognition

Semantic priming refers to a facilitation of responding speed due to the presentation of a semantically related word, while, similarly, phonological priming refers to improved recognition of a target word preceded by a word sharing the same phonological feature. Even though both of these priming effects were proved to be effective in lexical processing, it is still uncertain about whether there is difference between semantic priming effect and phonological priming effect in visual word recognition. This study focused on semantic and phonological priming effects in reading two-character Chinese words. With the lexical decision task, 18 native Mandarin speakers voluntarily took part in the experiment. It was shown that the responding speed to the target word preceded by semantic primes was faster than that preceded by phonological primes than that preceded by unrelated control primes. In other words, there are positive semantic and phonological priming effects in reading Chinese, and the effect of semantic priming is stronger than that of phonological priming. The findings supported dual-route model in lexical processing and shed more light on the studies concerning semantic and phonological priming effects in reading Chinese words.
