Numerous developmental findings suggest that infants and toddlers engage predictive processing during language comprehension. However, a significant limitation of this research is that associative (bottom-up) and predictive (top-down) explanations are not readily differentiated. Following adult studies that varied predictiveness relative to semantic-relatedness to differentiate associative vs. predictive processes, the present study used eye-tracking to begin to disentangle the contributions of bottom-up and top-down mechanisms to infants’ real-time language processing. Replicating prior results, infants (14-19 months old) use successive semantically-related words across sentences (e.g., eat, yum, mouth) to predict upcoming nouns (e.g., cookie). However, we also provide evidence that using successive semantically-related words to predict is distinct from the bottom-up activation of the word itself. In a second experiment, we investigate the potential effects of repetition on the findings. This work is the first to reveal that infant language comprehension is affected by both associative and predictive processes.

The present study investigated whether children’s difficulty with non-canonical structures is due to their non-adult-like use of linguistic cues or their inability to revise misinterpretations using late-arriving cues. We adopted a priming production task and a self-paced listening task with picture verification, and included three Mandarin non-canonical structures with differing word orders and the presence or absence of morphosyntactic cues. Forty five-to-ten-year-old Mandarin-speaking children were tested and compared to adults. Results showed that children were indistinguishable from adults in how they used different cues in real-time, although their performance in offline comprehension and production was more prone to errors but improved given the increase of age. These results suggest that the current child sample has adult-like cue-use patterns and use late-arriving cues to revise misinterpretations. The observed worse offline accuracy and production difficulties relative to adults result from their less developed domain-general abilities in performing tasks.

Seven decades after Brown v. Board, Black students continue to lag White students. This article analyzes six experiments conducted over three decades to study whether, consistent with social identity theory, White Americans are more supportive of funding increases for nonracially targeted educational programs that benefit their racial ingroup compared to race-targeted programs. We also ask whether racial prejudice is a factor, if implicit or explicit racial priming accounts for any observed differences, and if the effects have changed over time. Our results show that consistent with social identity theory, White Americans are more likely to favor funding increases for public schools or programs for poor children, categories that are majority White, than programs targeted to Black children. Furthermore, we find no evidence of implicit or explicit racial priming. Across all experiments and all years, interactions between racial priors and the treatments are null. We conclude that ingroup favoritism, not prejudice nor racial priming, explains racially discriminatory support for increases in education funding.

Using a priming paradigm, we investigated the processing of overtly identical verb forms with different sets of morphosyntactic features in L1 and L2 German. We found that more specific functions of a verb (inflected verbs) were better primes for less specific verb functions (past participles) than vice versa. For L1 speakers, these priming asymmetries were observed regardless of whether the lexical verb was repeated in prime and target or not (i.e., priming also for abstract configurations). For L2 learners, a similar but not native-like asymmetric priming pattern was seen only with repetition of the lexical verb. It was absent when the verb was not repeated. We conclude that in L2, morphosyntactic information is processed more on a lexical, item-based level compared to L1. We discuss our results in the context of several accounts, e.g., Shallow Structure Hypothesis, Declarative Procedural Model and the Ontogenesis Model of the L2 Lexical Representation.

Music and language are unique communication tools in human society, where stress plays a crucial role. Many studies have examined the recognition of lexical stress in Indo-European languages using beat/rhythm priming, but few studies have examined the cross-domain relationship between musical and linguistic stress in tonal languages. The current study investigates how musical stress and lexical stress influence lexical stress recognition in Mandarin. In the auditory priming experiment, disyllabic Mandarin words with initial or final stress were primed by disyllabic words or beats with either congruent or incongruent stress patterns. Results showed that the incongruent condition elicited larger P2 and the late positive component (LPC) amplitudes than the congruent condition. Moreover, the Strong-Weak primes elicited larger N400 amplitudes than the Weak-Strong primes, and the Weak-Strong primes yielded larger LPC amplitudes than the Strong-Weak primes. The findings reveal the neural correlates of the cross-domain influence between music and language during lexical stress recognition in Mandarin.

Results from earlier laboratory and field experiments were interrogated for the possibilities of sequestration, or long-term accumulation, of carbon from excess greenhouse gases in the atmosphere. In the laboratory study, samples of three (top) soils dominated by kaolinite and illite (together), smectite, and allophane were examined for the adsorption and desorption of dissolved organic carbon (DOC). Adsorption and desorption of DOC were carried out on clay fractions extracted physically and after first native organic matter and then iron oxides were removed chemically. Labeled organic material was added to the soils to assess the priming effect of organic carbon (OC). In the field, changes in OC were measured in sandy soils that had been amended by additions of clay for between 3 and 17 years, both through incorporation of exogenous clay and delving of in situ clay. The laboratory experiments demonstrated that a portion of DOC was held strongly in all soils. The amount of DOC adsorbed depended on clay mineral types, including Fe oxides. Much adsorbed DOC was lost by desorption in water and a substantial amount of native OC was lost on priming with new OC. Addition of clay to soils led to increased OC. Therefore, addition of clay to soil may enhance net sequestration of C. Organic carbon close to mineral surfaces or within microaggregates is held most strongly. Carbon sequestration may occur in subsoils with unsaturated mineral surfaces. However, incorporation of carbon into macroaggregates from enhanced plant growth might be most effective in removing excess carbon from the atmosphere, albeit over the short-term.

In producing linguistic variation, language users display a tendency to reuse the same variant. This paper compares the empirical properties of different types of repetitiveness in a single case study: locative variation in Chengdu Mandarin. Using conversational data from sociolinguistic interviews, we ask whether within-speaker repetitiveness (persistence) and cross-speaker repetitiveness (convergence) behave similarly with respect to (1) their sensitivity to the linguistic similarity of the prime and target, and (2) their tendency to decline with greater temporal distance between the prime and target. Our results suggest that intraspeaker persistence and interspeaker convergence behave similarly in both respects. We therefore propose that repetitiveness has a common underlying mechanism within and across speakers and encourage future work aimed at testing this hypothesis across other variables and varieties.

Code-switching is generally dispreferred at points of non-shared word order across a bilingual's two languages. In priming studies, this dispreference persists even following exposure to a code-switched non-shared-word-order utterance. The present study delves deeper into the scope of code-switching priming by investigating whether lexical repetition across target and prime, a factor known to boost structural priming, can increase code-switching at points of word order divergence. Afrikaans–English bilinguals (n=46) heard prime sentences in which word order, lexical repetition, and switch position were manipulated and subsequently produced code-switched picture descriptions. The results show that lexical repetition boosts the priming of code-switching in a non-shared word order. The findings demonstrate that code-switching in production is affected by a dynamic interplay between factors both language-internal (i.e., word order) and language-external (i.e., priming, and specifically lexical repetition).

We demonstrate that the desirability bias, the elevation of the estimated likelihood of a preferred event, can be due in part to the desire for consistency between the preference for the favored event and its predicted likelihood. An experiment uses a participant’s favorite team in Major League Baseball games and a recently devised method for priming the consistency goal. When preference is the first response, priming cognitive consistency moves prediction toward greater agreement with that preference, thereby increasing the desirability bias. In contrast, when prediction is the first response, priming cognitive consistency facilitates greater agreement with the factual information for each game. This increases the accuracy of the prediction and reduces the desirability bias.
