A growing body of evidence suggested that elapsing time is tightly associated with space in a specific way (e.g., Spatial Temporal Association of Response Codes or STARC effect). However, existing findings cannot justify a hypothesis that elapsing time is recoded directly into a spatial linear representation in working memory. The present study addresses this fundamental question by using three modified STARC-related working memory paradigms. In different experiments, participants were asked to give order judgment, order-irrelevant STM recognition judgment, or motor-related free-choice judgment, immediately after successive presentation of a set of disparate stimuli. Results show that responses to early stimuli were faster or more often with the left key and responses to late stimuli were faster or more often with the right key. These findings clearly support the hypothesis that elapsing time is directly and automatically recoded into a spatial linear representation in working memory.

Despite a long history of research favors left lateralization of language, increasingevidence provides support to the claim that the right hemisphere also plays a role inlanguage. Although studies have indicated that the right hemisphere contributes tolanguage representation, the underlying neural mechanisms are partly investigated andremain elusive. In this review, we hypothesize that the right hemisphere is involved inlanguage but its contributions are more likely to be domain-general rather than linguistic.The present work provides a thorough review of the growing body of research that hasdemonstrated how the right hemisphere is related to language with a focus on specificneural mechanisms underlying various aspects of language, and discusses why somebrain regions of the right hemisphere such as supramarginal gyrus are essential fordomain-general processes (e.g., verbal working memory) involved in language, ratherthan directly contributing to language itself.

Voluntary Sterilization

In this paper the author discusses the nature and importance of the right to reproduce, in particular the right to sterilisation. In the time past sterilization has been practiced only as a measure of penal policy or the prevention of mental health diseases. Today, mostly we can speak about the right to sterilization (especially reversible sterilization). The patient have a free choice to decide any method of contraception and that could be a voluntary sterilization (also called human, contraceptive, non-therapeutical in French law, and obliging in German law). Various legal questions about this right can be raised, in accordance of state of reproductive rights (how they are regulated by the law) and the protection of reproductive rights (especially the right of pregnant woman as a patient). Yugoslav law not yet has a complete regulation and adequate solutions in this area, except the abortion law. The primary gynecology care has contraceptive counseling, but concrete measures and education are insufficient. It cannot begin to give consistent answers to all of these questions without a coherent conception of the right to reproduce, which is the primary duty of legal experts.

Aim: This study tested sex differences in the association between hippocampal volume and working memory of a national sample of 9–10-year-old children in the US. As the hippocampus is functionally lateralized (especially in task-related activities), we explored the results for the right and the left hippocampus. Methods: This is a cross-sectional study using the Adolescent Brain Cognitive Development (ABCD) Study data. This analysis included baseline ABCD data (n = 10,093) of children between ages 9 and 10 years. The predictor variable was right and left hippocampal volume measured by structural magnetic resonance imaging (sMRI). The primary outcome, list sorting working memory, was measured using the NIH toolbox measure. Sex was the moderator. Age, race, ethnicity, household income, parental education, and family structure were the covariates. Results: In the overall sample, larger right (b = 0.0013; p < 0.001) and left (b = 0.0013; p < 0.001) hippocampal volumes were associated with higher children’s working memory. Sex had statistically significant interactions with the right (b = −0.0018; p = 0.001) and left (b = −0.0012; p = 0.022) hippocampal volumes on children’s working memory. These interactions indicated stronger positive associations between right and left hippocampal volume and working memory for females compared to males. Conclusion: While right and left hippocampal volumes are determinants of children’s list sorting working memory, these effects seem to be more salient for female than male children. Research is needed on the role of socialization, sex hormones, and brain functional connectivity as potential mechanisms that may explain the observed sex differences in the role of hippocampal volume as a correlate of working memory.

AbstractWorking memory and episodic memory are two different processes, although the nature of their interrelationship is debated. As these processes are predominantly studied in isolation, it is unclear whether they crucially rely on different neural substrates. To obtain more insight in this, 81 adults with sub-acute ischemic stroke and 29 elderly controls were assessed on a visual working memory task, followed by a surprise subsequent memory test for the same stimuli. Multivariate, atlas- and track-based lesion-symptom mapping (LSM) analyses were performed to identify anatomical correlates of visual memory. Behavioral results gave moderate evidence for independence between discriminability in working memory and subsequent memory, and strong evidence for a correlation in response bias on the two tasks in stroke patients. LSM analyses suggested there might be independent regions associated with working memory and episodic memory. Lesions in the right arcuate fasciculus were more strongly associated with discriminability in working memory than in subsequent memory, while lesions in the frontal operculum in the right hemisphere were more strongly associated with criterion setting in subsequent memory. These findings support the view that some processes involved in working memory and episodic memory rely on separate mechanisms, while acknowledging that there might also be shared processes.

This article examines in detail union busting in a nursing home facility in Florida and asks whether the Employee Free Choice Act (EFCA) would have protected workers' freedom to choose if it had been in effect at the time. It systematically applies EFCA's provisions to the events of the case and concludes that EFCA would have been helpful to the workers. However, EFCA would not have erased all obstacles to free employee choice, especially for low-wage workers like these. It also reveals that one of the least known features of EFCA would have been most crucial in this case.

Working memory enables us to hold in our ‘mind's eye’ the contents of our conscious awareness, even in the absence of sensory input, by maintaining an active representation of information for a brief period of time. In this review we consider the functional organization of the prefrontal cortex and its role in this cognitive process. First, we present evidence from brain–imaging studies that prefrontal cortex shows sustained activity during the delay period of visual working memory tasks, indicating that this cortex maintains on–line representations of stimuli after they are removed from view. We then present evidence for domain specificity within frontal cortex based on the type of information, with object working memory mediated by more ventral frontal regions and spatial working memory mediated by more dorsal frontal regions. We also propose that a second dimension for domain specificity within prefrontal cortex might exist for object working memory on the basis of the type of representation, with analytic representations maintained preferentially in the left hemisphere and image–based representations maintained preferentially in the right hemisphere. Furthermore, we discuss the possibility that there are prefrontal areas brought into play during the monitoring and manipulation of information in working memory in addition to those engaged during the maintenance of this information. Finally, we consider the relationship of prefrontal areas important for working memory, both to posterior visual processing areas and to prefrontal areas associated with long–term memory.

BackgroundPatients with major depressive disorder (MDD) show deficits in processing of facial emotions that persist beyond recovery and cessation of treatment. Abnormalities in neural areas supporting attentional control and emotion processing in remitted depressed (rMDD) patients suggests that there may be enduring, trait-like abnormalities in key neural circuits at the interface of cognition and emotion, but this issue has not been studied systematically.MethodNineteen euthymic, medication-free rMDD patients (mean age 33.6 years; mean duration of illness 34 months) and 20 age- and gender-matched healthy controls (HC; mean age 35.8 years) performed the Emotional Face N-Back (EFNBACK) task, a working memory task with emotional distracter stimuli. We used blood oxygen level-dependent (BOLD) functional magnetic resonance imaging (fMRI) to measure neural activity in the dorsolateral (DLPFC) and ventrolateral prefrontal cortex (VLPFC), orbitofrontal cortex (OFC), ventral striatum and amygdala, using a region of interest (ROI) approach in SPM2.ResultsrMDD patients exhibited significantly greater activity relative to HC in the left DLPFC [Brodmann area (BA) 9/46] in response to negative emotional distracters during high working memory load. By contrast, rMDD patients exhibited significantly lower activity in the right DLPFC and left VLPFC compared to HC in response to positive emotional distracters during high working memory load. These effects occurred during accurate task performance.ConclusionsRemitted depressed patients may continue to exhibit attentional biases toward negative emotional information, reflected by greater recruitment of prefrontal regions implicated in attentional control in the context of negative emotional information.

Abstract Visuospatial working memory (VSWM) plays an important role in arithmetic problem solving, and the relationship between these two skills is thought to change over development. Even though neuroimaging studies have demonstrated that VSWM and arithmetic both recruit frontoparietal networks, inferences about common neural substrates have largely been made by comparisons across studies. Little work has examined how brain activation for VSWM and arithmetic converge within the same participants and whether there are age-related changes in the overlap of these neural networks. In this study, we examined how brain activity for VSWM and arithmetic overlap in 38 children and 26 adults. Although both children and adults recruited the intraparietal sulcus (IPS) for VSWM and arithmetic, children showed more focal activation within the right IPS, whereas adults recruited the bilateral IPS, superior frontal sulcus/middle frontal gyrus, and right insula. A comparison of the two groups revealed that adults recruited a more left-lateralized network of frontoparietal regions for VSWM and arithmetic compared with children. Together, these findings suggest possible neurocognitive mechanisms underlying the strong relationship between VSWM and arithmetic and provide evidence that the association between VSWM and arithmetic networks changes with age.

The first step of a positive change in the system of service-legal relations is a change of view on the role and importance of service users. By providing opportunity to the service user to be an active and important member of the service-legal relationship, a far-reaching and universal value of humanization of the service economy sector is achieved. In such circumstances, the moral authority of the service law is realized through its justice and through voluntary obedience to the law of the subjects of the service-legal relationship. Precisely, this moral dimension of the rule of law, in the service economy sector is realized by applying the principles of service suitability and the right to free choice. In this regard, the paper analyzes the moral dimension and culture of the rule of law in the service sector, based on the principle of service suitability and the right to free choice, which are presented in the paper as guardians of justice of the service-legal norm.

A recent theory provides a unified cross-linguistic analysis of the interpretations that are assigned to expressions for disjunction, Negative Polarity Items, Free Choice Items, and the non-interrogative uses of wh-phrases in languages such as Mandarin Chinese. If this approach is on the right track, children should be expected to demonstrate similar patterns in the acquisition of these linguistic expressions. Previous research has found that, by age four, children have acquired the knowledge that both the existential indefinite renhe “any” and wh-words in Mandarin Chinese are interpreted as Negative Polarity Items when they are bound by downward entailing operators, but the same expressions are interpreted as Free Choice Items (with a conjunctive interpretation) when they are bound by deontic modals (Mandarin keyi) or by the Mandarin adverbial quantifier dou “all”. The present study extends this line of research to the Mandarin disjunction word huozhe. A Truth Value Judgment Task was used to investigate the possibility that disjunction phrases that are bound by the adverbial quantifier dou generate a conjunctive interpretation in the grammars of Mandarin-speaking 4-year-old children. The findings confirmed this prediction. We discuss the implications of the findings for linguistic theory and for language learnability.
