Enhancing speech perception in noise through articulation.

Considerable debate exists about the interplay between auditory and motor speech systems. Some argue for common neural mechanisms, whereas others assert that there are few shared resources. In four experiments, we tested the hypothesis that priming the speech motor system by repeating syllable pairs aloud improves subsequent syllable discrimination in noise compared with a priming discrimination task involving same-different judgments via button presses. Our results consistently showed that participants who engaged in syllable repetition performed better in syllable discrimination in noise than those who engaged in the priming discrimination task. This gain in accuracy was observed for primed and new syllable pairs, highlighting increased sensitivity to phonological details. The benefits were comparable whether the priming tasks involved auditory or visual presentation. Inserting a 1-h delay between the priming tasks and the syllable-in-noise task, the benefits persisted but were confined to primed syllable pairs. Finally, we demonstrated the effectiveness of this approach in older adults. Our findings substantiate the existence of a speech production-perception relationship. They also have clinical relevance as they raise the possibility of production-based interventions to improve speech perception ability. This would be particularly relevant for older adults who often encounter difficulties in perceiving speech in noise.

Can Professionals Resist Cognitive Bias Elicited by the Visual System? Reversed Semantic Prime Effect and Decision Making in the Workplace: Reaction Times and Accuracy.

Information that comes from the environment reaches the brain-and-body system via sensory inputs that can operate outside of conscious awareness and influence decision processes in different ways. Specifically, decision-making processes can be influenced by various forms of implicit bias derived from individual-related factors (e.g., individual differences in decision-making style) and/or stimulus-related information, such as visual input. However, the relationship between these subjective and objective factors of decision making has not been investigated previously in professionals with varying seniority. This study explored the relationship between decision-making style and cognitive bias resistance in professionals compared with a group of newcomers in organisations. A visual "picture-picture" semantic priming task was proposed to the participants. The task was based on primes and probes' category membership (animals vs. objects), and after an animal prime stimulus presentation, the probe can be either five objects (incongruent condition) or five objects and an animal (congruent condition). Behavioural (i.e., accuracy-ACC, and reaction times-RTs) and self-report data (through the General Decision-Making Scale administration) were collected. RTs represent an indirect measure of the workload and cognitive effort required by the task, as they represent the time it takes the nervous system to receive and integrate incoming sensory information, inducing the body to react. For both groups, the same level of ACC in both conditions and higher RTs in the incongruent condition were found. Interestingly, for the group of professionals, the GDMS-dependent decision-making style negatively correlates with ACC and positively correlates with RTs in the congruent condition. These findings suggest that, under the incongruent decision condition, the resistance to cognitive bias requires the same level of cognitive effort, regardless of seniority. However, with advancing seniority, in the group of professionals, it has been demonstrated that a dependent decision-making style is associated with lower resistance to cognitive bias, especially in conditions that require simpler decisions. Whether this result depends on age or work experience needs to be disentangled from future studies.

Can I still eat this? Using implicit and explicit measures to explore consumer behavior toward food products with date labels

This study investigates implicit and explicit attitudes toward products before and beyond the best-before date (BBD) using an Implicit Association Test and an online questionnaire. Moreover, we test whether consumer perception of and behavior toward products beyond the BBD can be manipulated using a priming task. We use a three-group between-subjects design where respondents had to recall either a frugal, a wasteful, or an unrelated behavior. Results show that consumers have negative implicit associations with products beyond the BBD. Reduced health and safety perceptions, consumers’ strategies to determine edibility, and general risk perception of products beyond the BBD predict consumption of these products. While recalling a frugal behavior does not have significant effects, recalling a wasteful behavior prior to evaluating products beyond the BBD leads to a decrease in the perceived safety and healthfulness of these products.

When You Think of and Identify Yourself as a Nurse, You Will Become More Deontological and Less Utilitarian.

This study aims to examine how the activation of the role of nursee and professional identification as a nurse can influence moral judgments in terms of deontological and utilitarian inclinations. In Study 1, a priming technique was used to assess the impact of activating the nursing concept on moral reasoning. Participants were randomly assigned to either a nursing prime or neutral prime condition. By using a scrambled-sentence task, participants were prompted to think about nursing-related or neutral thoughts. Following the priming task, participants were asked to respond to 20 moral dilemmas. The process dissociation approach was employed to measure the degree of deontological and utilitarian tendencies in their moral reasoning. In Study 2, participants completed the nursing profession identification scale and the moral orientation scale before engaging in moral judgments similar to those in Study 1. The findings revealed that priming the concept of being a nursee resulted in an increase in deontological clinical inclinations while having no significant effect on utilitarian inclinations. Additionally, a positive correlation was observed between identification with the nursing profession and deontological clinical inclinations, whereas a negative correlation was found with utilitarian inclinations. Deliberation orientation acted as a complete mediator in the relationship between nursing professional identification and deontological tendencies and as a partial mediator for utilitarian tendencies.

Lexical-semantic activation in French-Spanish or French-English bilingual toddlers: An event-related potential (ERP) investigation

Both behavioral and neurophysiological evidence shows that lexical-semantic organization emerges by two years in monolingual children. Research in bilingual children is more scarce, and there is only a limited amount of neurophysiological evidence of the effect of language dominance on lexical-semantic activation. In the present event-related potential (ERP) study, we investigated whether bilingual French-Spanish and French-English learning 24- to 30-month-olds activate semantic relations between words similarly in their both languages, and whether the priming effects are similar in children learning two different language pairs. Participants were presented with related and unrelated dominant and non-dominant language word pairs in a within-language lexical-semantic priming paradigm. The amplitudes of N400 were modulated by trial type, language dominance and language group. A language-independent priming effect - more pronounced N400 amplitudes for unrelated than for related target words - was found in the group of toddlers learning French and Spanish. In the group of toddlers learning French and English, a priming effect was observed only in their non-dominant language. Our results propose that the language pair may contribute to lexical-semantic facilitation in priming tasks during early childhood.

Emotion expression salience and racially biased weapon identification: A diffusion modeling approach.

Racial stereotypes are commonly activated by informational cues that are detectable in people's faces. Here, we used a sequential priming task to examine whether and how the salience of emotion (angry/scowling vs. happy/smiling expressions) or apparent race (Black vs. White) information in male face primes shapes racially biased weapon identification (gun vs. tool) decisions. In two experiments (Ntotal = 546) using two different manipulations of facial information salience, racial bias in weapon identification was weaker when the salience of emotion expression versus race was heightened. Using diffusion decision modeling, we tested competing accounts of the cognitive mechanism by which the salience of facial information moderates this behavioral effect. Consistent support emerged for an initial bias account, whereby the decision process began closer to the "gun" response upon seeing faces of Black versus White men, and this racially biased shift in the starting position was weaker when emotion versus race information was salient. We discuss these results vis-à-vis prior empirical and theoretical work on how facial information salience moderates racial bias in decision-making.

Beyond self-report measures of arousal: A new priming task to capture activation of relaxing and energizing feelings elicited by odors

The Olfactory Priming Task (OPT) is a new implicit measure developed to capture associations between odors and feeling-related words that was inspired by previous priming techniques. Participants are presented with feeling-related words and asked to categorize them as “relaxing” or “energizing” as quickly and accurately as possible, while supposedly relaxing or stimulating odors are delivered as a prime. Accuracy and response times are recorded, and participants are expected to react faster and more accurately with feeling-related words that are congruent with the primed odor. We validated the OPT in two experiments with the use of menthol/vanillin and fine fragrances, respectively. Results indicated that the OPT could discriminate odors from their relaxing/energizing properties, with participants showing faster responses to energizing-related words after priming with menthol or “Perfume 1” and to relaxing-related words after priming with vanillin or “Perfume 2.” These associations were further confirmed by subjective reports, with participants rating menthol and Perfume 1 as more energizing and vanillin and Perfume 2 as more relaxing. The results suggest that exposure to relaxing/energizing odors activates congruent feelings in consumers. The results also demonstrate the validity and reliability of the OPT as an implicit measure for capturing associations between odors and feeling-related words, making it a valuable tool for measuring consumers' affective response to flavors and fragrances.

Diagnosis support of major depressive disorder using event-related potentials during affective priming tasks

Major Depressive Disorder (MDD) is a global problem. Currently, the most common diagnosis is based on criteria susceptible to the subjectivity of the patient and the clinician. A possible solution to this problem is to look for diagnostic biomarkers that can accurately and early detect this mental condition. Some researchers have focused on electroencephalogram (EEG) analysis to identify biomarkers. In this study we used a dataset composed of EEG recordings from 24 subjects with MDD and 29 healthy controls (HC), during the execution of affective priming tasks with three different emotional stimuli (images): fear, sadness, and happiness. We investigated abnormalities in depressed patients using a novel technique, by directly comparing Event-Related Potential (ERP) waveforms to find statistically significant differences between the MMD and HC groups. Compared to the control group (healthy subjects), we found out that for the emotions fear and happiness there is a decrease in cortical activity at temporal regions in MDD patients. Just the opposite, for the emotion sadness, an increase in MDD brain activity occurs in frontal and occipital regions. Our findings suggest that emotions regulate the attentional control of cognitive processing and are promising for clinical application in diagnosing patients with MDD more objectively.

Dimensions of a hyper memory: investigating the factors modulating exceptional retrieval in a single case of highly superior autobiographical memory (HSAM)

ABSTRACT Highly Superior Autobiographical Memory (HSAM) is a rare form of exceptional memory, characterised by an ability to recall personal episodes in response to dates. The single case “DT” is one of less than 100 HSAM individuals globally, and little is known about how these individuals organise the vast number of events they can recollect. We administered 2 novel priming tasks to explore navigation between autobiographical memories. In both tasks, a “prime” date appeared on the screen and DT was instructed to access and begin reliving a specific memory from that date. After 3 s, a “target” date appeared, and DT switched to the new memory. Latencies were recorded. Experiment 1 explored the influence of emotional valence on memory navigation. DT was quicker moving from positive or negative memories to neutral memories, compared to between neutral memories, supporting the role of emotionality in connecting memories in HSAM. Experiment 2 investigated semantic content and mental timeline configuration's role in organisation. DT was faster moving forward (e.g., 1996–1997) than backwards (e.g., 2023–2022), indicating a forwards perception of time. No differences were observed regarding semantic content. Results provide insight into DT's memory dimensions and support the use of this task to explore organisation.

Social power modulates individuals’ neural responses to monetary and social rewards

Although previous research has shown that social power modulates individuals’ sensitivity to rewards, it is currently unclear whether social power increases or decreases individuals’ sensitivity to rewards. This study employed event-related potentials (ERPs) to investigate the effects of social power on individuals’ neural responses to monetary and social rewards. Specifically, participants underwent an episodic priming task to manipulate social power (high-power vs. low-power) and then completed monetary and social delayed incentive tasks while their behavioral responses and electroencephalograms (EEG) were recorded. According to ERP analysis, during the anticipatory stage, low-power individuals exhibited a greater cue-P3 amplitude than high-power individuals in both monetary and social tasks. In the consummatory stage, though no impact of social power on the reward positivity (RewP) was found, low-power individuals showed a higher feedback-P3 (FB-P3) amplitude than high-power individuals, regardless of task types (the MID and SID tasks). In conclusion, these results provide evidence that social power might decrease one’s sensitivity to monetary and social rewards in both the anticipatory and consummatory stages.

The psycholinguistics of shining-through effects in translation: cross-linguistic structural priming or serial lexical co-activation?

AbstractThe manuscript explores the psycholinguistic processes responsible for cross-linguistic influence in translation. In two experimental studies with professional translators-in-training, we investigate the psycholinguistic foundations of shining-through effects in translated texts, i.e., cases where the grammatical structure of a source sentence leaves traces in the translated sentence. Experiment 1 reports the results from a translation task investigating the influence of the grammatical structure of the source sentence on structural choices for its translation. The results showed a significant influence of source sentence structure, which gradually decreased with increasing translation competence scores. In Experiment 2, we investigated to what extent the effect of source structure influence found in Experiment 1 can be accounted for through cross-linguistic structural priming. In a cross-linguistic priming experiment in which the source sentences from Experiment 1 were used as primes, participants showed no evidence of structural priming. A cross-experiment comparison revealed significant source sentence influence in the translation task, but no such effect in the priming task, for matched sets of sentences. Our results cast doubt on the claim that shining-through effects in translation are caused by cross-linguistic structural priming. We suggest an alternative account which instead explains structural cross-linguistic influence in translation through serial lexical co-activation.

Effects of retrieval schedules on the acquisition of explicit, automatized-explicit, and implicit knowledge of L2 collocations

AbstractThis study investigates the effects of retrieval schedules on the acquisition of second language (L2) collocations. Chinese learners of English first studied 36 target verb-noun collocations using flashcards and form-meaning matching practice. Subsequently, the participants practiced retrieving the target collocations from memory, following either a massed (consecutive) or spaced schedule. After each retrieval attempt, corrective feedback was provided. The acquisition of L2 collocations was measured by near-immediate and 1-week delayed posttests that assessed explicit knowledge with an offline form recall task, automatized explicit knowledge using an online acceptability judgment task, and implicit knowledge with an online collocation priming (lexical decision) task. Results showed equal learning effects of massed and spaced retrieval at both posttests of explicit knowledge and the near-immediate posttest of automatized explicit knowledge. The spacing effect was observed for the implicit knowledge across the two posttests and the automatized explicit knowledge at the delayed posttest.

The Effects of Buddhist Religiosity and Aspects on Prosociality

ABSTRACT Religion prosociality hypothesis, which predicts that religion promotes prosocial behaviors, has been verified by previous empirical research. However, the religion in the previous studies investigating Eastern religions has often been examined as a single and unified concept. In the current study, based on a few studies in the context of Western religions, we considered the religiosity as a complex construct and investigated the influence of Buddhist religiosity and primed Buddhist and Christian aspects on prosociality through two studies. In Study 1, participants’ prosocial tendencies were measured by the Prosocial Tendencies Measure (PTM). In Study 2, we employed a subliminal priming task to investigate the effects of aspects of Buddhist and Christian traditions on prosociality measured by self-reports with explicit requests for donating money amount in nonbelievers. The results of Study 1 revealed that Buddhist believers exhibited more prosocial tendencies than nonbelievers, and female participants exhibited more prosocial tendencies than male participants. Study 2’s results showed that the Buddhist and Christian priming groups exhibited more prosocial intentions than the neutral priming group. Furthermore, for the group primed with the Buddhist words, the aspect of the spiritual activated more prosocial intentions than did the aspect of the agents and institutional. Taken together, these findings suggest that Buddhism, especially the spiritual component of Buddhism, increased prosocial tendencies.

Effects of Lexical Priming on Priming Type and Presence of Distractors in Persons with Mild Cognitive Impairment

Objectives: The purpose of the study is to examine if the lexical priming effect is valid in persons with mild cognitive impairment (MCI). In addition, this study attempted to examine the correlation between working memory and sentence production ability for MCI and healthy adults (HA).Methods: Fifteen individuals with MCI and sixteen HA described action pictures in sentences following lexical (agent or theme) primes. Priming effect was analyzed in terms of priming type and presence of distractor.Results: 1) Persons with MCI did show significantly lower proportion of passive sentences compared to HA. Overall, the proportion of passives were significantly higher in the theme primed condition versus the agent primed condition. 2) The difference in the presence of distractor stimuli in the agent primed condition was significantly larger than in the theme primed condition. 3) It was observed that the better the working memory ability of MCI participants, the higher the production of active sentences when compared with passive sentences in the theme primed condition.Conclusion: Persons with MCI used word-driven information as a strategy of sentence production like HA did. In addition, MCI participants showed difficulty in production of complex structures such as passive sentences. In previous research, most of the studies examined the priming effect through structural priming tasks for HA and aphasia patients. The results of this study also showed the effect of lexical priming in persons with MCI, and the finding of lower production of passive sentences in persons with MCI compared to HA emphasized the linguistic deficits that may appear in individuals with MCI.

A comparison of learning and retention of a syntactic construction between Cantonese-speaking children with and without DLD in a priming task

Procedural circuit Deficit Hypothesis (PDH) of Developmental Language Disorder (DLD) predicts problems with learning and retention of grammar. Twenty 7- to 9-year-old Cantonese-speaking children with DLD and their typically developing (TD) age peers participated in a syntactic priming task that was given in two sessions one week apart. Production of Indirect Object Relative Clause (IORC) was tested using a probe test before and after the priming task, and one week later. The study involved two cycles of learning and retention, and two levels of prior knowledge. Bayesian linear mixed effects modelling was used for data analysis. Children with DLD learned, and possibly retained, IORC less well than TD children after age, working memory and general grammatical knowledge were controlled for. No interaction effects were significant, meaning that cycle and prior knowledge affected both groups similarly in learning and retention. Results were discussed in relation to PDH and the Complementary Learning Systems Theory.

Investigating implicit emotion processing in autism spectrum disorder across age groups: A cross-modal emotional priming study.

Cumulating evidence suggests that atypical emotion processing in autism may generalize across different stimulus domains. However, this evidence comes from studies examining explicit emotion recognition. It remains unclear whether domain-general atypicality also applies to implicit emotion processing in autism and its implication for real-world social communication. To investigate this, we employed a novel cross-modal emotional priming task to assess implicit emotion processing of spoken/sung words (primes) through their influence on subsequent emotional judgment of faces/face-like objects (targets). We assessed whether implicit emotional priming differed between 38 autistic and 38 neurotypical individuals across age groups as a function of prime and target type. Results indicated no overall group differences across age groups, prime types, and target types. However, differential, domain-specific developmental patterns emerged for the autism and neurotypical groups. For neurotypical individuals, speech but not song primed the emotional judgment of faces across ages. This speech-orienting tendency was not observed across ages in the autism group, as priming of speech on faces was not seen in autistic adults. These results outline the importance of the delicate weighting between speech- versus song-orientation in implicit emotion processing throughout development, providing more nuanced insights into the emotion processing profile of autistic individuals.

Long-term Functional Connectivity Alterations in the Mismatch Negativity, P300 and N400 Language Potentials in Adults with a Childhood Acquired Brain Injury

ABSTRACT Objective To investigate whether alterations in the functional connectivity of networks underlying phoneme perception and semantic-categorical processing persist in adulthood following childhood acquired brain injury (cABI). Methods EEG was recorded in seven adults with a cABI and seven matched controls during the administration of an inattentive and attentive phoneme-level oddball task and a categorical priming task. Functional connections underlying the mismatch negativity (MMN), P300 and N400 were compared between participant groups in five frequency bands by calculating the weighted phase lag index between 32 × 32 electrode pairs. Network modularity and path length were compared between the cABI and control group. Results We observed a positive network for MMN deviant processing in the low gamma band and N400 related processing in the alpha band, but a negative network for P300 standard processing in the theta band in cABI compared to control adults. No differences in graph measures of functional networks were observed between participant groups. Conclusions Alterations in the functional connectivity of speech perception and semantic-categorical processing networks persist in adulthood following cABI. Nevertheless, normal-like network properties in terms of local segregation and global integration are observed.

Regular exposure facilitates dual-mapping of Cantonese pronunciation variants

Abstract The multilingual landscape of Canada creates opportunities for many heterogeneous bilingual communities to experience systematic phonetic variation within and across languages and dialects, and exposes listeners to different pronunciation variants. This paper examines phonetic variation through the lens of an ongoing sound change in Cantonese involving word-initial [n] and [l] across two primed lexical decision tasks (Experiment 1: Immediate repetition priming task, Experiment 2: Long-distance repetition priming task). Our main question is: How are sound change pronunciation variants recognized and represented in a Cantonese-English bilingual lexicon? The results of both experiments suggest that [n]- and [l]-initial variants facilitate processing in both short and long-term spoken word recognition. Thus, regular exposure to Cantonese endows bilingual listeners with the perceptual flexibility to dually and gradiently map pronunciation variants to a single lexical representation.

Lexical encoding of second language tones in English learners of Mandarin

The study investigates how native and non-native differences in tone perception influence lexical encoding of second language (L2) tones. Previous work shows that tone language listeners perceived tones as phonemic categories while non-tone language listeners relied more on psychoacoustic cues such as pitch height to discriminate stimulus tones. However, little is known about the influence of such differences in perception on L2 tonal encoding. In the present study, two experiments were conducted with nineteen English learners of Mandarin and 20 Mandarin native speakers. Experiment 1 was an ABX task. Results showed that while native speakers’ overall performance was superior to L2 listeners’, both groups poorly discriminated tone pairs with shared tone contours (i.e., T2-T3). Experiment 2 was a medium-lag repetition priming task. In the repetition condition, significant facilitations were observed in both language groups. In the minimal-tone-pair condition, despite T2-T3 contrasts posing greater challenge for both groups to accurately distinguish than other tonal contrasts as shown in Experiment 1, positive priming was observed only in the L2 group. The findings from the two experiments suggest that the L2 listeners, although quite proficient in Mandarin, have yet to achieve native-like competence in regard to lexical tones.
