Although the five primary senses have traditionally been thought of as separate, examples of their interactions, as well as the neural substrate possibly underlying them, have been identified. Arm position sense, for example, depends on touch, proprioception, and spatial vision of the limb. It is, however, unknown whether position sense is also influenced by more fundamental, nonspatial visual information. Here, we report an illusion that demonstrates that the position sense of the eyelid partly depends on information regarding the relative illumination reported by the two eyes. When only one eye is dark-adapted and both eyes are exposed to a dim environment, the lid of the light-adapted eye feels closed or “droopy.” The effect decreases when covering the eye by hand or a patch, thus introducing tactile information congruent with the interocular difference in vision. This reveals that the integration of vision with touch and proprioception is not restricted to higher-level spatial vision, but is instead a more fundamental aspect of sensory processing than has been previously shown.

Over the past 15 years, there has been considerable debate concerning the extent to which insomnia patients can be classified into diagnostic sUbtypes. Despite this debate, relatively little research has been conducted to empirically determine whether naturally occurring insomnia subtypes might be identified within populations of sleep clinic patients. In the current study we used a hierarchical cluster analysis to empirically identify subtypes among a mixed group of normal sleepers and the insomnia outpatients who presented to our sleep center over the past decade. Using factor-analytically derived composite variables that summarized data obtained from sleep history questionnaires and polysomnographic monitoring, this clustering procedure resulted in the identification of 14 subgroups that varied between four and 34 patients/subjects in size. Subsequently, subgroup mean scores for the composite variables used in the clustering procedure were used to construct profiles for each of the 14 clusters. A multivariate profile analysis, employed to elucidate subgroup differences, showed that these cluster profiles differed in terms of their configural shapes, average elevations, and degrees of interscale differences. Furthermore, both DSM-III-R (American Psychiatric Association) and International Classification of Sleep Disorders (ICSD) insomnia diagnoses, assigned independent of cluster findings, suggested that these subtypes differed significantly in regard to their diagnostic compositions. Nevertheless, a far-from-perfect concordance was observed between such clinically assigned diagnoses and cluster group membership. In fact, many of the empirically identified groups were composed of various DSM-III-R and/or ICSD diagnostic SUbtypes. These results provided only partial support for current DSM and ICSD insomnia categories. However, our results support the existence of multiple, clinically discrete insomnia subtypes and provide information that may be useful in future revisions of current insomnia nosologies.

Over the past decade, self-administered mindfulness interventions, such as those administered via phone apps, have become increasingly popular. However, their effectiveness for regulating stress is unclear. In a multi-site study (Nsites = 37, Nparticipants = 2,239; all fluent English speakers) we experimentally investigated the efficacy of four single, stand-alone mindfulness exercises (versus three active control conditions) on self-reported stress with Bayesian mixed-effects models. All mindfulness exercises proved to be more efficacious than the active control conditions in reducing participants' self-reported stress levels. Between the control condition (M = 1.95) and the condition with the largest reduction in stress levels (Body Scan; M = 1.68), there was a mean difference of 0.27 on a four-point scale, (Cohen’s d = -.56) indicating a small decrease in stress. Our findings suggest that brief mindfulness exercises may be beneficial in reducing stress, even though we cannot ...

In response to the COVID-19 pandemic, governments have implemented a wide range of non-pharmaceutical interventions (NPIs). Monitoring and documenting government strategies during the COVID-19 crisis is crucial to understand the progression of the epidemic. Following a content analysis strategy of existing public information sources, we developed a specific hierarchical coding scheme for NPIs. We generated a comprehensive structured dataset of government interventions and their respective timelines of implementation. To improve transparency and motivate collaborative validation process, information sources are shared via an open library. We also provide codes that enable users to visualise the dataset. Standardization and structure of the dataset facilitate inter-country comparison and the assessment of the impacts of different NPI categories on the epidemic parameters, population health indicators, the economy, and human rights, among others. This dataset provides an in-depth insig...

Teleworking, as a new method of work, implies working out of a designated office space using informational technologies. As a modern work practice, it became popular in recent years but abruptly developed in the last two years with the COVID 19 pandemic when a large number of companies were forced to perform remotely resulting in challenges. This research aims to examine how mental health can affect work performance in teleworking employees. The sample holds 134 respondents conventionally and remotely employed in Serbia who were interviewed using the CES-D self-assessment scale, with 20 questions measuring depressive symptomatology. This study demonstrates the connection between the methods of work and the mental state and their influence on work results. Teleworkers in Serbia show higher values of depression than conventional employees which can negatively affect their work performance. This research contributes to the improvement of remote employee management in Serbia and gives r...

Infants' and young children's perception of the unity of musical events was investigated in three studies. In the first two, children watched video displays of two musicians playing different musical instruments side by side in synchrony, and heard a soundtrack in synchrony with both instruments but specific to one. The children judged which instrument was producing the music they heard. Three-to 4-year-olds differentiated instruments from different families but not instruments from the same family. Five-to 7-year-olds additionally differentiated instrument pairs differing in size and pitch range (e.g., violin, cello). In the third study, infants were presented some of the same musical events in order to assess whether specific experience with the instruments is necessary for perceiving the unity of musical events. Looking times revealed that 7-to 9-month-olds detected the correspondence of the sight and sound of some musical instruments. Specific experience with a variety of instruments is evidently not necessary for detecting correspondences of audible and visible properties and for differentiating instruments from different families. Perceiving events usually is a multisensory experience, and an important question about the development of perception of events is how we come to discern their unity. When an infant sees and hears his or her father singing a lullaby, how We thank the infants, children, parents, and teachers whose participation and assistance made this research possible. We gratefully acknowledge the assistance at various phases of the research of
