Abstract In this paper, we explore the role of cognition in bilingual syntactic processing by employing a structural priming paradigm. A group of Norwegian-English bilingual children and an age-matched group of Norwegian monolingual children were tested in a priming task that included both a within-language and a between-language priming condition. Results show that the priming effect between-language was not significantly smaller than the effect within-language. We argue that this is because language control mechanisms do not affect the access to the shared grammar. In addition, we investigate the interaction between the children’s performance in the priming task and in a non-linguistic cognitive task and find that the two measures are not correlated; however, we find a correlation between the cognitive task and language control, which we measured by counting the number of trials produced in the non-target language. Our findings suggest that language control and domain-general executive control overlap only partially.

Language Control

Simultaneous interpreting is a complex cognitive task that requires the concurrent execution of multiple processes: listening, comprehension, conversion of a message from one language to another, speech production, and self-monitoring. This requires the deployment of an array of linguistic and cognitive control mechanisms that must coordinate the various brain systems implicated in handling these tasks. How the brain handles this challenge remains an open question, and recent brain imaging investigations have begun to complement the theories based on behavioural data. fMRI studies have shown that simultaneous interpreting engages a network of brain regions encompassing those implicated in speech perception and production, language switching, self-monitoring, and selection. Structural imaging studies have been carried out that also indicate modifications to a similar set of structures. In the present paper, we review the extant data and propose an integrative model of simultaneous interpreting that piggybacks on existing theories of multilingual language control.

How do faces with social-cultural identity affect bilingual language control? We approach this question by looking at the switch cost patterns and reversed language dominance effect, which are suggested to reflect bilingual language control mechanisms, in the absence (i.e., baseline context) or presence of faces with socio-cultural identity (Asian or Caucasian). In separate blocks, the face matched (i.e., congruent context) or mismatched (i.e., incongruent context) the language to be spoken. In addition, cue preparation time was manipulated to be long (Experiment 1) or short (Experiment 2). In both experiments, a unique asymmetric switch cost with larger costs for L2 was observed in the congruent context as compared with the baseline and incongruent contexts. Furthermore, the reversed language dominance effect was not modulated across contexts. These results suggest a critical role of contextual faces in modulating local but not global language control. Thus, bilingual language control changes flexibly within an environment that includes faces with socio-cultural identity.

The current experiment investigated bilingual language control within the dual mechanisms framework. In an fMRI investigation of morphosyntactic rule production, the presence or absence of target language cues was manipulated to investigate the neural mechanisms associated with proactive and reactive global language control mechanisms. Patterns of activation across nine regions of interest (ROIs) were investigated in seventeen early Spanish–English bilingual speakers. A cue by phase interaction in the left dorsolateral prefrontal cortex (DLPFC) and pre-supplementary motor area (Pre-SMA) was observed, suggesting that these regions were more active during cue phases, and less active during execution phases, when target language cues were presented. Individual differences analyses showed that variability in proactive control (informative > non-informative cued trial activation during preparation) in the basal ganglia was correlated with proactive control in the left DLPFC, left inferior frontal gyrus (IFG), and right precentral ROIs. In contrast, reactive control (non-informative > informative cued activation during execution) in the anterior cingulate was correlated with reactive control in the Pre-SMA and left orbital frontal ROIs. The results suggest that, consistent with the dual mechanisms framework, bilinguals differ in the degree to which they use cues to proactively prepare to use a target language.

Abstract Language control is important for bilinguals to produce words in the right language. While most previous studies investigated language control using visual stimuli with vocal responses, language control regarding auditory stimuli and manual responses was rarely examined. In the present study, an alternating language switching paradigm was used to investigate language control mechanism under two input modalities (visual and auditory) and two output modalities (manual and vocal) by measuring switch costs in both error percentage and reaction time (RT) in forty-eight Cantonese–English early bilinguals. Results showed that higher switch costs in RT were found with auditory stimuli than visual stimuli, possibly due to shorter preparation time with auditory stimuli. In addition, switch costs in RT and error percentage could be obtained not only in speaking, but also in handwriting. Therefore, language control mechanisms, such as inhibition of the non-target language, may be shared between speaking and handwriting.

Regulatory Flexibility

Seed rules and regulations determine who can produce and sell seeds, which varieties will be available in the market, the quality of seed for sale, and where seed can be bought and sold. The legal and regulatory environment for seed impacts all stakeholders, including those in the informal sector, through shaping who can participate in the market and the quality and diversity of seed available. This paper addresses a gap in the current literature regarding the role of law and regulation in linking the informal and formal seed sectors and creating more inclusive and better governed seed systems. Drawing upon insights from the literature, global case studies, key expert consultations, and a methodology on the design and implementation of law and regulation, we present a framework that evaluates how regulatory flexibility can be built into seed systems to address farmers’ needs and engage stakeholders of all sizes. Our study focuses on two key dimensions: extending market frontiers and liberalizing seed quality control mechanisms. We find that flexible regulatory approaches and practices play a central role in building bridges between formal and informal seed systems, guaranteeing quality seed in the market, and encouraging market entry for high-quality traditional and farmer-preferred varieties.

There are few studies which report on the personnel practices in the American states. A survey of state compensation analysts in the Summer of 1987 elicited information concerning the use of compensation controls in state government. Results indicate that with the exception of wage and salary surveys, data concerning compensation controls is rarely collected. Initial analysis indicates that the role of the legislature and the existence of collective bargaining may have an impact on the number of controls used.

Recent research has explored the role of empathy in the context of music listening. Here, through an empathy priming paradigm, situational empathy was shown to act as a causal mechanism in inducing emotion, although the way empathy was primed had low levels of ecological validity. We therefore conducted an online experiment to explore the extent to which information about a composer’s expressive intentions when writing a piece of music would significantly affect the degree to which participants reportedly empathise with the composer and in turn influence emotional responses to expressive music. A total of 229 participants were randomly assigned to three groups. The experimental group read short texts describing the emotions felt by the composer during the process of composition. To control for the effect of text regardless of its content, one control group read texts describing the characteristics of the music they were to hear, and a second control group was not given any textual information. Participants listened to 30-second excerpts of four pieces of music, selected to express emotions from the four quadrants of the circumplex theory of emotion. Having heard each music excerpt, participants rated the valence and arousal they experienced and completed a measure of situational empathy. Results show that situational empathy in response to music is significantly associated with trait empathy. As opposed to those in the control conditions, participants in the experimental group responded with significantly higher levels of situational empathy. Receiving this text significantly moderated the effect of the expressiveness of stimuli on induced emotion, indicating that it induced empathy. We conclude that empathy can be induced during music listening through the provision of information about the specific emotions of a person relating to the music. These findings contribute to an understanding of the psychological mechanisms that underlie emotional responses to music.

Optokinetic Afternystagmus

Different types of fast eye movements, including saccades and fast phases of optokinetic nystagmus (OKN) and optokinetic afternystagmus (OKAN), are coded by only partially overlapping neural networks. This is a likely cause for the differences that have been reported for the dynamic parameters of fast eye movements. The dependence of two of these parameters—peak velocity and duration—on saccadic amplitude has been termed “main sequence.” The main sequence of OKAN fast phases has not yet been analyzed. These eye movements are unique in that they are generated by purely subcortical control mechanisms and that they occur in complete darkness. In this study, we recorded fast phases of OKAN and OKN as well as visually guided and spontaneous saccades under identical background conditions because background characteristics have been reported to influence the main sequence of saccades. Our data clearly show that fast phases of OKAN and OKN differ with respect to their main sequence. OKAN fast phases were characterized by their lower peak velocities and longer durations compared with those of OKN fast phases. Furthermore we found that the main sequence of spontaneous saccades depends heavily on background characteristics, with saccades in darkness being slower and lasting longer. On the contrary, the main sequence of visually guided saccades depended on background characteristics only very slightly. This implies that the existence of a visual saccade target largely cancels out the effect of background luminance. Our data underline the critical role of environmental conditions (light vs. darkness), behavioral tasks (e.g., spontaneous vs. visually guided), and the underlying neural networks for the exact spatiotemporal characteristics of fast eye movements.

Objective. Stress-reducing therapies help maintain cognitive performance during stress. Aromatherapy is popular for stress reduction, but its effectiveness and mechanism are unclear. This study examined stress-reducing effects of aromatherapy on cognitive function using the go/no-go (GNG) task performance and event related potentials (ERP) components sensitive to stress. The study also assessed the importance of expectancy in aromatherapy actions.Methods. 81 adults were randomized to 3 aroma groups (active experimental, detectable, and undetectable placebo) and 2 prime subgroups (prime suggesting stress-reducing aroma effects or no-prime). GNG performance, ERPs, subjective expected aroma effects, and stress ratings were assessed at baseline and poststress.Results. No specific aroma effects on stress or cognition were observed. However, regardless of experienced aroma, people receiving a prime displayed faster poststress median reaction times than those receiving no prime. A significant interaction for N200 amplitude indicated divergent ERP patterns between baseline and poststress for go and no-go stimuli depending on the prime subgroup. Furthermore, trends for beneficial prime effects were shown on poststress no-go N200/P300 latencies and N200 amplitude.Conclusion. While there were no aroma-specific effects on stress or cognition, these results highlight the role of expectancy for poststress response inhibition and attention.
