A significant relationship between a sense of power and financial risk-taking has been established in the literature. However, the boundary conditions for this relationship remain unclear. This article presents the results of an online experimental study (N = 192) that explores the moderating role of cognitive load in the relationship between power and financial risk-taking in the domains of gambling and investing. The findings validate a positive association between a sense of power and financial risk-taking, alongside a negative impact of cognitive load on financial risk. Notably, cognitive load moderates the relationship between power and financial risk-taking in a way that the link is positive when individuals have full access to their cognitive resources, but it becomes nonsignificant when they are under cognitive load.

When learning new words, listeners must contend with multiple sources of ambiguity and variability. Research has revealed that learners can resolve referential ambiguity by tracking co-occurrence statistics between words and their referents across multiple exposures over time-a process termed cross-situational word learning (XSWL). However, the degree to which variability in the input, such as input from multiple speakers, and variability in learner experience, such as bilingual language experience, modulate XSWL remains unclear. In this study, we examined the effects of speaker variability in XSWL performance in monolingual adults and bilingual adults with a range of second language backgrounds and language acquisition histories. Results revealed above-chance word learning in both the single and the multiple-speaker conditions across language groups. An advantage for word learning was observed in the single-speaker condition, but the effects of bilingual language experience were null. This research adds to the limited body of work dedicated to extending theories of statistical learning to account for variations in both input and learner characteristics as well as their interactions.

This article presents the results of two experiments conducted to examine how ellipsis sites are processed during the processing of backward sluicing, which is superficially similar to non-sluicing wh-filler-gap dependencies. Previous studies on long-distance wh-filler-gap dependencies established that the processing of these dependencies is sensitive to the syntactic structure of materials within the dependency: CP vs. NP. Results from two maze experiments show that backward sluicing processing is sensitive to the same structural factors, confirming that the same processing mechanism underlies both constructions. We suggest that an active search mechanism is operating at the core for these structures and with the interaction of the ellipsis-specific mechanism, e.g., a word-by-word copying mechanism, the parser builds antecedent structure within the ellipsis site incrementally during the processing of backward sluicing.

Seeing the visual articulatory movements of a speaker, while hearing their voice, helps with understanding what is said. This multisensory enhancement is particularly evident in noisy listening conditions. Multisensory enhancement also occurs even in auditory-only conditions: auditory-only speech and voice-identity recognition are superior for speakers previously learned with their face, compared to control learning; an effect termed the "face-benefit." Whether the face-benefit can assist in maintaining robust perception in increasingly noisy listening conditions, similar to concurrent multisensory input, is unknown. Here, in two behavioural experiments, we examined this hypothesis. In each experiment, participants learned a series of speakers' voices together with their dynamic face or control image. Following learning, participants listened to auditory-only sentences spoken by the same speakers and recognised the content of the sentences (speech recognition, Experiment 1) or the voice-identity of the speaker (Experiment 2) in increasing levels of auditory noise. For speech recognition, we observed that 14 of 30 participants (47%) showed a face-benefit. 19 of 25 participants (76%) showed a face-benefit for voice-identity recognition. For those participants who demonstrated a face-benefit, the face-benefit increased with auditory noise levels. Taken together, the results support an audio-visual model of auditory communication and suggest that the brain can develop a flexible system in which learned facial characteristics are used to deal with varying auditory uncertainty.

The Implicit Association Test (IAT) is a widely used measure of implicit attitudes. Despite its application in various fields, the malleability of the IAT by different methodological factors has been shown frequently. In this article, we focus on two factors that potentially influence the IAT effect, but which have received either inconsistent or no support so far: the IAT version (i.e., picture-word IAT vs. word IAT) and the position of the attribute labels on the screen (i.e., the positive or negative label on the left side). In two experiments, we used the original flower-insect IAT to systematically analyse the effects of the position of attribute labels (i.e., the assignment of the positive or the negative attribute label to the left screen position) and the block order of compatible (e.g., flower and positive) and incompatible blocks (e.g., flower and negative) as between-subjects factors. Reliable IAT effects were observed for the picture-word IAT and the word IAT when calculating the IAT effect as a difference in the response times as well as when computing the recommended D Score as IAT outcome. Smaller IAT effects occurred in the picture-word IAT than in the word IAT, supporting existing literature. In addition, an effect of the position of the attribute labels on the screen was found in both experiments, resulting in larger IAT effects when the negative attribute label was positioned on the left. This effect also appeared when calculating the D Score. The study highlights the importance of methodical factors for the IAT outcome.

While the impact of visual letter similarity on word recognition in the Latin script has been extensively documented using masked priming techniques, research into non-Latin scripts such as Hangul remains limited. Hangul letters are systematically formed by adding one or two strokes to the base form, creating a pool of visually similar letters in the inventory. This study investigated the role of added distinctive strokes in word recognition by employing two experimental tasks: a lexical decision task (Experiment 1) and a same-different word matching task (Experiment 2). The results of Experiment 1 revealed a visual similarity effect only for primes without distinctive strokes, indicating an asymmetry in the priming effects. Conversely, Experiment 2 showed that visually similar primes facilitated target word processing regardless of the presence of the distinctive stroke, indicating no asymmetric priming effect. These findings suggest initial uncertainty of letter identity during Korean word processing and the processing of distinctive strokes in differentiating visually similar words.

Measurement of cognitive functions is typically based on the implicit assumption that the mental architecture underlying cognitive task performance is constant throughout the task. In contrast, skill learning theory implies that cognitively demanding task performance is an adaptive process that progresses from initial heavy engagement of effortful and task-general metacognitive and executive control processes towards more automatic and task-specific performance. However, this hypothesis is rarely applied to the short time spans of traditional cognitive tasks such as working memory (WM) tasks. We utilised longitudinal structural equation models on two well-powered data sets to test the hypothesis that the initial stages of WM task performances load heavily on a task-general g-factor and then start to diverge towards factors specific to task structure. In line with the hypothesis, data from the first experiment (N = 296) were successfully fitted in a model with task-initial unity of the WM paradigm-specific latent factors, after which their intercorrelations started to diverge. The second experiment (N = 201) replicated this pattern except for one paradigm-specific latent factor. These preliminary results suggest that the processes underlying WM task performance tend to progress rapidly from more task-general towards task-specific, in line with the cognitive skill learning framework. Such task-internal dynamics has important implications for the measurement of complex cognitive functions.

Previous studies using cognates with the same writing system have found cognate facilitation effect in the lexical processes of spoken and typewritten productions and cognate interference effect in the sub-lexical process of typewritten production. This study focused on cross-script cognates, Chinese-English, which have different writing systems, and explored cognate effects based on the input and output modalities by using a Chinese-English translation task. Experiment 1 was under visual input modality and investigated the cross-script cognate effect in all three output modalities: spoken, typewritten and handwritten. Results revealed a cognate facilitation effect in the lexical processes across all three output modalities. However, it showed a cognate facilitation effect rather than a cognate interference effect in the sub-lexical process of typewritten production. Experiment 2 was under auditory input modality and focused on exploring cross-script cognate effect on typewritten and handwritten modalities, finding a consistent result on cognate effects with Experiment 1. Both experiments showed higher accuracy for cognates, and there was no significant difference in cgnate effect between visual and auditory inputs. In summary, these findings indicated that the use of cross-script cognates could effectively mitigate cognate interference. While spoken, handwritten and typewritten production share lexical processes, differences emerge in sub-lexical processes, with spoken production being less influenced by orthography. Furthermore, combining the results of Experiments 1 and 2, typewritten production may lean towards the phonological route while handwritten production may favour the direct lexical-orthographic route in the sub-lexical processes.

Vowel harmony is a phenomenon in which the vowels in a word share some features (e.g., frontness vs. backness). It occurs in several families of languages (e.g., Turkic and Finno-Ugric languages) and serves as an effective segmenting cue in continuous speech and when reading compound words. The present study examined whether vowel harmony also plays a role in visual word recognition. We chose Turkish, a language with four front and four back vowels in which approximately 75% of words are harmonious. If vowel harmony contributes to the formation of coherent phonological codes during lexical access, harmonious words will reach a stable orthographic-phonological state more rapidly than disharmonious words. To test this hypothesis, in Experiment 1, we selected two types of monomorphemic Turkish words: harmonious (containing only front vowels or back vowels) and disharmonious (containing front and back vowels)-a parallel manipulation was applied to the pseudowords. Results showed faster lexical decisions for harmonious than disharmonious words, whereas vowel harmony did not affect pseudowords. In Experiment 2, where all words were harmonious, we found a small but reliable advantage for disharmonious over harmonious pseudowords. These findings suggest that vowel harmony helps the formation of stable phonological codes in Turkish words, but it does not play a key role in pseudoword rejection.

Name agreement (NA) refers to the degree to which speakers agree on a picture's name. A robust finding is that speakers are faster to name pictures with high agreement (HA) than those with low agreement (LA). This NA effect is thought to occur because LA pictures strongly activate several names, so speakers need time to select one. HA pictures, in contrast, strongly activate a single name, so there is no need to select one name out of several alternatives. Recent models of lexical access suggest that the structure of the mental lexicon changes with experience. Thus, speakers should consider a range of names when naming LA pictures, but the extent to which they consider each of these names should change with experience. We tested these hypotheses in two picture-naming experiments. In Experiment 1, participants were faster to name LA than HA pictures when they named each picture once. Importantly, they were faster to produce modal names (provided by most participants) than alternative names for LA pictures, consistent with the view that speakers activate multiple names for LA pictures. In Experiment 2, participants were familiarised with the modal name before the experiment and named each picture three times. Although there was still an NA effect when participants named the pictures the first time, it was reduced in comparison to Experiment 1 and was further reduced with each picture repetition. Thus, familiarisation and repetition reduced the NA effect but did not eliminate it, suggesting speakers activate a range of plausible names.
