Evaluating the Replicability of Social Priming Studies

To assess the replicability of social priming findings we reviewed the extant close replication attempts in the field. In total, we found 70 close replications, that replicated 49 unique findings. Ninety-four percent of the replications had effect sizes smaller than the effect they replicated and only 17% of the replications reported a significant p-value in the original direction. The strongest predictor of replication success was whether or not the replication team included at least one of the authors of the original paper. Twelve of the 18 replications with at least one original author produced a significant effect in the original direction and the meta-analytic average of these studies suggest a significant priming effect (d = 0.40, 95% CI[0.23; 0.58]). In stark contrast, none of the 52 replications by independent research teams produced a significant effect in the original direction and the meta-analytic average was virtually zero (d = 0.002, 95% CI[-0.03; 0.03]). We argue that these results have shifted the burden of proof back onto advocates of social priming. Successful replications from independent research teams will likely be required to convince sceptics that social priming exists at all.

Does affective processing require awareness? On the use of the Perceptual Awareness Scale in response priming research.

Masked priming paradigms are frequently used to shine light on the processes of nonconscious cognition. Introducing a new method to this field, Lähteenmäki et al. (2015) claimed that affective priming requires awareness. Specifically, they administered a subjective rating task after the priming task in each trial to directly assess awareness of the prime. Their main result was a lack of priming for subjectively unaware primes. In four experiments, we compared their method with the traditional paradigm, that is, a single-task priming phase followed by a direct test of prime recognition. We used faces with anger versus sadness expressions as primes and targets; emotion categorization was the task. In contrast to Lähteenmäki et al., primes and targets were drawn from different sets, such that priming effects can be unequivocally attributed to the processing of evaluative features. In Experiments 1a, b, we followed their approach of using different prime durations to produce variance in awareness ratings. With a duration of 40 ms, significant priming effects for subjectively unaware primes were found. This duration was also associated with priming effects in the traditional paradigm with near-zero objective prime categorization, suggesting that priming does not require awareness. In Experiment 2a, employing a constant 40-ms duration, we replicated the traditional effect. However, the parallel Experiment 2b with subjective awareness ratings produced a null result at a sharply increased response time level. We conclude that the claim that affective processing requires awareness is not justified. Subjective trial-by-trial visibility ratings can severely alter processing strategies in response priming paradigms. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

Syntactic priming as implicit learning in German child language.

We investigated syntactic priming in German children to explore crosslinguistic evidence for implicit learning accounts of language production and acquisition. Adult descriptions confirmed that German speakers (N=27) preferred to spontaneously produce active versus passive transitive and DO versus PO dative forms. We tested whether German-speaking children (N=29, M age =5.3, 15 girls/14 boys) could be primed to produce these dispreferred forms and whether such priming effects would persist across a target phase. Children first heard a block of priming sentences and then described a block of target pictures. They demonstrated significant priming effects for passive and PO dative structures, and these priming effects did not differ between the first and second halves of the block of target trials. These patterns of German child language production are consistent with implicit learning accounts of syntactic priming.

Spinal cord microglia drive sex differences in ethanol-mediated PGE2-induced allodynia

The mechanisms of how long-term alcohol use can lead to persistent pain pathology are unclear. Understanding how earlier events of short-term alcohol use can lower the threshold of non-painful stimuli, described as allodynia could prove prudent to understand important initiating mechanisms. Previously, we observed that short-term low-dose alcohol intake induced female-specific allodynia and increased microglial activation in the spinal cord dorsal horn. Other literature describes how chronic ethanol exposure activates Toll-like receptor 4 (TLR4) to initiate inflammatory responses. TLR4 is expressed on many cell types, and we aimed to investigate whether TLR4 on microglia is sufficient to potentiate allodynia during a short-term/low-dose alcohol paradigm. Our study used a novel genetic model where TLR4 expression is removed from the entire body by introducing a floxed transcriptional blocker (TLR4-null background (TLR4LoxTB)), then restricted to microglia by breeding TLR4LoxTB animals with Cx3CR1:CreERT2 animals. As previously reported, after 14 days of ethanol administration alone, we observed no increased pain behavior. However, we observed significant priming effects 3 hrs post intraplantar injection of a subthreshold dose of prostaglandin E2 (PGE2) in wild-type and microglia-TLR4 restricted female mice. We also observed a significant female-specific shift to pro-inflammatory phenotype and morphological changes in microglia of the lumbar dorsal horn. Investigations in pain priming-associated neuronal subtypes showed an increase of c-Fos and FosB activity in PKCγ interneurons in the dorsal horn of female mice directly corresponding to increased microglial activity. This study uncovers cell- and female-specific roles of TLR4 in sexual dimorphisms in pain induction among non-pathological drinkers.

Effects of Seed Priming on Germination of Nigella sativa L. and Comparison of Germination Performance with Yield Parameters in Field Conditions

The utilization of Nigella sativa L., commonly known as black cumin, in traditional and medicinal practices is well-documented, attributing to its wide-ranging biological activities. Given its significance, this study explores the efficacy of various seed priming treatments (control, distilled water, potassium humate, and gibberellic acid) under laboratory and field conditions to enhance the early growth stages of Nigella sativa L. Priming treatments aimed to improve germination rates, plant height, and other growth parameters, potentially translating into increased agricultural productivity. According to results plant height ranged from 52.38 to 58.91 cm, number of branches between 3.76 and 3.98 (branch plant-1). The number of capsules varied from 4.93 to 6.81 (capsule plant-1), capsule seed weight was between 0.19 and 0.22 (gram capsule-1 ), and the thousand-seed weight ranged from 2.26 to 2.39 grams. The germination rate ranged from 78% to 93%, germination index 4.22-5.83 and mean germination time was observed from 4.27 to 4.82 days. Our findings reveal significant effects of priming on germination parameters and plant height, this offering insights into the potential of these treatments to optimize crop growth. However, the transition of these benefits to field conditions, particularly yield-related parameters, appeared limited, suggesting the complex nature of growth enhancement strategies and their implications for agricultural practices.

Masked Translation Priming Effects for Chinese-English-Japanese Triple Cognates in Lexical Decision Tasks.

Previous research has demonstrated cognate translation priming effects in masked priming lexical decision tasks (LDTs) even when a bilingual's two languages have different scripts. Because those effect sizes are normally larger than with noncognates, the effects have been partially attributed to the impact of prime-target phonological similarity. The present research extended that work by examining priming effects when using triple different-script cognates, i.e., /ka1 feɪ1/-coffee-コーヒー/KoRhiR/. Specifically, masked cognate priming effects were examined in six different priming directions (i.e., L1↔L2, L1↔L3, and L2↔L3) for Chinese-English-Japanese trilinguals using LDTs. Significant priming effects were observed only when the primes were from the stronger language. This asymmetric pattern suggests that the phonological similarity of cognate primes only facilitates the processing of different-script triple cognates to the extent that the processing of the prime is robust enough to make phonology available before target processing is finished.

Question-Order Effect in the Study of Satisfaction with Democracy: Lessons from Three Split-Ballot Experiments

This study examines question-order effects in measuring satisfaction with democracy (SWD). Particularly, the authors are interested in whether the relative position of the question regarding satisfaction with the state of the economy (SWE) in the questionnaire affects responses to the SWD item. The authors conducted three independent split-ballot experiments in Hungary between March 2021 and May 2022. They report a significant and substantial negative priming effect that possibly leads to a systematic underestimation of SWD. Importantly, the authors find no question-order effect in the measurement of SWE. The analysis further reveals a contrast effect: when the SWD question is primed, the difference between SWE and SWD means increases. The authors’ final recommendation is that researchers either put the SWD question before the SWE item to avoid question-order bias or randomize question order. These findings should assist future data collection efforts (comparative or single-country studies) in developing and integrating a battery of satisfaction items into questionnaires and help users assess data quality.

The Effects of Problematic Internet Use and Emotional Connotation on Internet Slang Processing: Evidence from a Lexical Decision Task.

Young people use slang for identifying themselves with a particular social group, gaining social recognition and respect from that group, and expressing their emotional state. One feature of Internet slang is its active use by youth in online communication, which, under certain conditions, may cause problematic Internet use (PIU). We conducted two studies in young Russian speakers (n1 = 115, n2 = 106). In study 1, participants were asked to rate a set of slang and common words using Self-Assessment Manikin. The study revealed that the most reliable predictor of higher emotional ratings was word familiarity. There were no significant effects of slang vs. common words or word frequency. In study 2, we used a dual lexical decision task to reveal the effects of word characteristics and propensity for PIU on reaction time (RT) for Internet slang words in pairs with semantically related vs. unrelated common words. Study 2 did not reveal any significant semantic priming effect. Word frequency was a significant predictor of lexical decision facilitation. Common, but not slang, word valence and dominance significantly affected RT in the opposite direction. Individuals with higher cognitive preoccupation with the Internet responded significantly faster, while those more likely to use online communication for mood regulation responded significantly slower to the stimuli. Apparently, on explicit and implicit levels, in-depth knowledge of Internet slang can be one the PIU markers. The results are discussed in line with Davis' approach to determining the general pathological Internet use.

Evidence for a constituent order boost in structural priming

The study investigates the role of constituent order in structural priming. We report the results from a PO/DO priming experiment in German, in which we experimentally manipulated verb position in primes and targets. Significant structural priming effects occurred irrespective of whether verb position was the same in prime and target or not. However, additional similarity in constituent order was able to boost structural priming effects, with significantly stronger priming when the verb occurred in the same position in prime and target. We argue that existing one-stage and two-stage accounts of formulation struggle to account for the entire data pattern and propose an alternative account of formulation which can explain our results.

Can Popular Word Search Puzzles Affect Walking Speed in Older Adults?

We examined whether supraliminal word stimuli can affect walking speed of older adults in laboratory settings. The 78 physically active subjects (age >65 years) were randomly assigned to prime and control conditions. All subjects walked 19 m measured distance pre- and post-completing a word search puzzle containing either words associated with early adulthood or neutral ones. Although participants in the prime group went faster in the posttest, the ANOVA did not reveal significant interaction between the subjects’ conditions and walking speed. No significant priming effect of exposure to words on walking speed in older adults was detected in the current study. There is a need for further research, as there is a lack of data in this age cohort. The priming effect could possibly be used to increase the physical activity of seniors and may bias the clinical outputs in gait tests.

Stress priming transcranial direct current stimulation (tDCS) enhances updating of emotional content in working memory

Transcranial direct current stimulation (tDCS) targeting the prefrontal cortex has emerged as a valuable tool in psychiatric research. Understanding the impact of affective states, such as stress at the time of stimulation, on the efficacy of prefrontal tDCS is crucial for advancing tDCS interventions. Stress-primed tDCS, wherein stress is used as a priming agent, has the potential to modulate neural plasticity and enhance cognitive functions, particularly in emotional working memory. However, prior research using stress-primed tDCS focused solely on non-emotional working memory performance, yielding mixed results. In this sham-controlled study, we addressed this gap by investigating the effects of stress-primed bifrontal tDCS (active versus sham) on both non-emotional and emotional working memory performance. The study was conducted in 146 healthy individuals who were randomly assigned to four experimental groups. The Trier Social Stress Test (TSST) or a control variant of the test was used to induce a stress versus control state. The results showed that stress priming significantly enhanced the effects of tDCS on the updating of emotional content in working memory, as evidenced by improved accuracy. Notably, no significant effects of stress priming were found for non-emotional working memory performance. These findings highlight the importance of an individual's prior affective state in shaping their response to tDCS, especially in the context of emotional working memory.

Phonological planning in Cantonese–English bilingual speech production

Purpose: Findings from previous speech production research suggest that the nature of phonological planning units is language-specific, with phonemes as the planning units in Dutch and English but syllables in Cantonese and Mandarin Chinese. However, little is known about how multilingual speakers possessing languages with distinctive phonological planning units plan for their speech. This study was conducted to investigate the roles of syllable and phoneme in Cantonese (L1) and English (L2) production among Cantonese–English bilinguals. Design: A picture version of the form-preparation task was employed, where participants named aloud (in their L1 and L2) small sets of pictures repeatedly. The names of the pictures in a set either shared the same word-initial syllable, word-initial phoneme, or were unrelated. Participants’ L1 and L2 proficiencies were measured. Data and analysis: 53 Cantonese–English bilinguals participated. The naming latency data were submitted for linear mixed effects modeling analyses. Findings: Significant priming effects on naming latency, relative to an unrelated control, were found when the response words shared the same word-initial syllable but null effects were found when they shared merely the same word-initial phoneme in both L1 and L2 production. Critically, in L2 English production, a significant negative association was observed between the size of syllable priming and the participant’s English vocabulary size. Furthermore, significant English phonemic priming was observed among the participants higher in spoken English proficiency but not among the lower proficiency counterparts. Originality: This study provides clear evidence showing the multifaceted effects of L2 proficiency on L2 phonological planning using a picture naming task. Significance: The present findings indicate the significant impact of L1 on L2 phonological planning. Yet, this L1-to-L2 influence would be modulated in different ways by the different aspects of one’s L2 proficiency.

An ART Tour de Force on Mental Imagery: Vividness, Individual Bias Differences, and Complementary Visual Processing Streams

Grossberg’s adaptive resonance theory (ART) provides a framework for understanding possible interactions between mental imagery and visual perception. Our purpose was to integrate, within ART, the phenomenological notion of mental image vividness and thus investigate the possible biasing effects of individual differences on visual processing. Using a Vernier acuity task, we tested whether indirect estimation of relative V1 size (small, medium, large) and self-reported vividness, in three subgroups of 53 observers, could predict significant effects of priming, interference, or more extreme Perky effects (negative and positive), which could be induced by imagery, impacting acuity performance. The results showed that small V1 was correlated with priming and/or negative Perky effects independently of vividness; medium V1 was related to interference at low vividness but priming at high vividness; and large V1 was related to positive Perky effects at high vividness but negative Perky effects at low vividness. Our interpretation of ART and related modeling based on ARTSCAN contributes to expanding Grossberg’s comprehensive understanding of how and why individually experienced vividness may drive the differential use of the dorsal and ventral complementary visual processing pathways, resulting in the observed effects of imagery on concurrent perception.

The Contribution of Aspirated Feature Information of Initial in Mandarin-Chinese Monosyllable Word Processing

The passage mainly focuses on aspirated feature of stop consonants priming effect in Mandarin-Chinese monosyllable real spoken words. The experiment contrasted 4 prime conditions of prime-target pairs: homogeneous (pa1-pa1), aspirated feature (pha1-pa1), post-homogeneous (ma1-pa1) and unrelated (lu1-pa1). In the experiment, all tonal information is matched and the aspirated feature of initial in Mandarin-Chinese monosyllable real spoken words is the variant. The latter two pairs are control groups. The data were from ten Mandarin native listeners, then they were calculated and got the mean reaction time (RT), the standard deviation (std) and standard error (std. err). By comparing with the unrelated group, the other three shows that if some segmental information are matched, there will be significant negative priming effect. The first two pairs test whether aspirated feature activate priming effect at word recognition in Mandarin-Chinese monosyllable real spoken words by auditory priming, by comparing the homogeneous (H) group with the aspirated group and post-homogeneous group, the result shows that changing the aspirated feature do have a positive priming effect.

Cognate translation priming with Chinese-Japanese bilinguals: No effect of interlingual phonological similarity.

Previous masked translation priming studies, especially those with different-script bilinguals, have shown that cognates provide more priming than noncognates, a difference attributed to cognates' phonological similarity. In our experiments employing a word naming task, we examined this issue for Chinese-Japanese bilinguals in a slightly different way, using same-script cognates as primes and targets. In Experiment 1, significant cognate priming effects were observed. The sizes of the priming effects were, however, statistically not different for phonologically similar (e.g., /xin4lai4/-/shiNrai/) and dissimilar cognate pairs (e.g., /bao3zheng4/- /hoshoR/), suggesting no impact of phonological similarity. In Experiment 2, using exclusively Chinese stimuli, we demonstrated a significant homophone priming effect using two-character logographic primes and targets, indicating that phonological priming is possible for two-character Chinese targets. However, priming only emerged for pairs that had the same tone pattern (e.g., /shou3wei4/-/shou3wei4/), suggesting that a match in lexical tone is crucial for observing phonologically based priming in that situation. Therefore, Experiment 3 involved phonologically similar Chinese-Japanese cognate pairs in which the similarity of their suprasegmental phonological features (i.e., lexical tone and pitch-accent information) was varied. Priming effects were statistically not different for tone/accent similar pairs (e.g., /guan1xin1/-/kaNsiN/) and dissimilar pairs (e.g., /man3zu2/-/maNzoku/). Our results indicate that phonological facilitation is not involved in producing cognate priming effects for Chinese-Japanese bilinguals. Possible explanations, based on underlying representations of logographic cognates, are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Rime Priming Effects in Spoken Word Recognition.

In this study, we re-examined the facilitation that occurs when auditorily presented monosyllabic primes and targets share their final phonemes, and in particular the rime (e.g., /vɔʀd/-/kɔʀd/). More specifically, we asked whether this rime facilitation effect is also observed when the two last consonants of the rime are transposed (e.g., /vɔʀd/-/kɔʀd/). In comparison to a control condition in which the primes and the targets were unrelated (e.g., /pylt/-/kɔʀd/), we found significant priming effects in both the rime (/vɔdʀ/-/kɔʀd/) and the transposed-phoneme "rime" /vɔdʀ/-/kɔʀd/ conditions. We also observed a significantly greater priming effect in the former condition than in the latter condition. We use the theoretical framework of the TISK model (Hannagan et al., 2013) to propose a novel account of final overlap phonological priming in terms of activation of both position-independent phoneme representations and bi-phone representations.

Automatic phonological access among bilinguals with cross-script languages.

This study investigated the hypothesis of nonselective access to phonological representations in an integrated lexicon across logographic and alphabetic writing systems among Chinese L1 (first language)-English L2 (second language) bilinguals. We employed three experiments to test this hypothesis, including a lexical decision task (LDT) and a word naming task in Experiments 1 and 2 using the masked priming paradigm, and a self-paced sentence reading task in Experiment 3. Results from the LDT and the word naming task showed a significant homophone priming effect from L1 to L2, but not from L2 to L1. In the sentence reading task, we compared processing time between homophone error words and control words in the critical and spill-over regions. A slower processing effect in the homophone condition was observed in the spill-over region. Overall, these findings suggest that phonological priming occurs across a logographic and an alphabetic script in different tasks, whether reading isolated words or sentences. Bilingual reading involves an integrated bilingual lexicon that is independent of script similarity.

Molecular and Dual-Isotopic Profiling of the Microbial Controls on Nitrogen Leaching in Agricultural Soils under Managed Aquifer Recharge.

Nitrate (NO3-) leaching is a serious health and ecological concern in global agroecosystems, particularly those under the application of agricultural-managed aquifer recharge (Ag-MAR); however, there is an absence of information on microbial controls affecting NO3- leaching outcomes. We combine natural dual isotopes of NO3- (15N/14N and 18O/16O) with metagenomics, quantitative polymerase chain reaction (PCR), and a threshold indicator taxa analysis (TITAN) to investigate the activities, taxon profiles, and environmental controls of soil microbiome associated with NO3- leaching at different depths from Californian vineyards under Ag-MAR application. The isotopic signatures demonstrated a significant priming effect (P < 0.01) of Ag-MAR on denitrification activities in the topsoil (0-10 cm), with a 12-25-fold increase of 15N-NO3- and 18O-NO3- after the first 24 h of flooding, followed by a sharp decrease in the enrichment of both isotopes with ∼80% decline in denitrification activities thereafter. In contrast, deeper soils (60-100 cm) showed minimal or no denitrification activities over the course of Ag-MAR application, thus resulting in 10-20-fold of residual NO3- being leached. Metagenomic profiling and laboratory microcosm demonstrated that both nitrifying and denitrifying groups, responsible for controlling NO3- leaching, decreased in abundance and potential activity rates with soil depth. TITAN suggested that Nitrosocosmicus and Bradyrhizobium, as the major nitrifier and denitrifier, had the highest and lowest tipping points with regard to the NO3- changes (P < 0.05), respectively. Overall, our study provides new insight into specific depth limitations of microbial controls on soil NO3- leaching in agroecosystems.

The influence of semantic predictability on transposition effects in Chinese and English

Abstract Semantic predictability is one of the important factors that influence word processing and recognition. Based on the SPaM paradigm (Self-paced reading + Masked priming), the present study explores the influence of semantic predictability on TL effects in Chinese and English. The findings show that in both languages, internal and final transpositions produce priming effect in low-predictability preceding and following contexts as well as in high-predictability following contexts. From the perspective of priming magnitude, internal transposition produces greater priming effect than final transposition in English, while in Chinese, final transposition produces greater priming effect than internal transposition. In high-predictability preceding contexts, internal and final transpositions reveal significant priming effect and initial transposition produces close-to-significant-level priming effect in English, while in Chinese, no significant priming effect is observed in initial, internal or final transpositions.

Does linear position matter for morphological processing? Evidence from a Tagalog masked priming experiment

ABSTRACT This study investigated morphological decomposition of Tagalog infixed, prefixed, and suffixed words using the masked priming paradigm. We directly compared morphological priming of <in> infixed, ni- prefixed and -in suffixed words to examine whether infixes are processed similarly to other affixes during early and automatic decomposition. We found significant priming effects for infixed, prefixed, and suffixed words, but no semantic or orthographic similarity priming. Magnitudes of priming effects for infixed and prefixed words were not significantly different, suggesting that decomposition of infixed words was not more costly for Tagalog speakers, contrary to phonological readjustment-based accounts of infixation. This is the first psycholinguistic experiment showing that infixed words are decomposed into morphological units during visual word recognition. We provide evidence that the imperfect edge-alignment of the stem within infixed words does not hamper the early morphological decomposition mechanisms, suggesting that edge-alignment might not be critical to trigger activation of morphological units.
