We report here the first experiment of a series studying the effect of task structure and difficulty demand on time-sharing performance and workload in both automated and corresponding manual systems. The experimental task involves manual control time-shared with spatial and verbal decisions tasks of two levels of difficulty and two modes of response (voice or manual). The results provide strong evidence that tasks and processes competing for common processing resources are time shared less effectively and have higher workload than tasks competing for separate resources. Subjective measures and the structure of multiple resources are used in conjunction to predict dual task performance. The evidence comes from both single task and from dual task performance.

Perceptual Factors

Perceptual bias is inherent to all our senses, particularly in the form of visual illusionsand aftereffects. However, many experiments measuring perceptual biases may besusceptible to non-perceptual factors, such as response bias and decision criteria. Here wequantify how robust Multiple Alternative Perceptual Search (MAPS) is for disentanglingestimates of perceptual biases from these confounding factors. First our results show thatwhile there are considerable response biases in our four-alternative forced choice design,these are unrelated to perceptual biases estimates, and these response biases are notproduced by the response modality (keyboard versus mouse). We also show that perceptualbias estimates are reduced when feedback is given on each trial, likely due to feedbackenabling observers to partially (and actively) correct for perceptual biases. However, thisdoes not impact the reliability with which MAPS detects the presence of perceptual biases.Finally, our results show that MAPS can detect actual perceptual biases and is not adecisional bias towards choosing the target in the middle of the candidate stimulusdistribution. In summary, researchers conducting a MAPS experiment should use a constantreference stimulus, but consider varying the mean of the candidate distribution. Ideally,they should not employ trial-wise feedback if the magnitude of perceptual biases is ofinterest.

The paper describes the current state of development of seasickness as one of movement disease variants. The given type of pathology occurs when combining different types of ship’s motion (rolling and pitching). Circular, vertical and slow movements induce more pronounced and frequent signs of seasickness than linear, horizontal and quick ones. In the view of majority of researchers, the most likely is an intersensory conflict theory i.e. violation of coherent functioning of afferent body systems performing spatial orientation, statokinetic equilibrium and keeping balance. The leading role is played by the functional dysfunction of the vestibular analyzer. The classification of means of preventing and stopping of motion sickness is given, the mechanisms of their action, specific activity and side effects are described. It has been shown that currently the most effective drugs are M-cholinergic antagonists (scopolamine hydrobromide) and H1-histamine antagonists of the 1st generation (dimenhydrinate, diphenhydramine, cyclizine, meclizine, promethazine, etc.). Of the antipsychotics and blockers of D2 receptors, prochlorperazine and metoclopramide are recommended. It is also worth to use prokinetics (domperidone, cisapride, renzapride, etc.), tranquilizers (barbiturates, benzodiazepines), sleeping pills and local anesthetics. Particular attention is paid to combination drugs, consisting of antiemetic and psychostimulating drugs, designed to maintain working capacity under the influence of seasickness factors on the body. Non-pharmacological means of preventing seasickness and alleviating its symptoms are described. The main directions of improving the system of measures aimed at maintaining efficiency in the presence of symptoms of seasickness are determined.

Purpose This article presents a viewpoint highlighting concerns regarding currently available assessments of working memory in adults with neurogenic communication disorders. Additionally, we provide recommendations for improving working memory assessment in this population. Method This viewpoint includes a critique of clinical and experimental working memory tests relevant to speech-language pathologists. We consider the terminology used to describe memory, as well as discuss language demands and test construction. Results Clinical and experimental testing of working memory in adults with neurogenic communication disorders is challenged due to theoretical, methodological, and practical limitations. The major limitations are characterized as linguistic and task demands, presentation and response modality effects, test administration, and scoring parameters. Taking these limitations into consideration, several modifications to working memory testing and their relevance to neurogenic populations are discussed. Conclusions The recommendations provided in this article can better guide clinicians and researchers to advocate for improved tests of working memory in adults with neurogenic communication disorders. Future research should continue to address these concerns and consider our recommendations.
