Subjective Equality Research Articles

The method of Veniamin Fedorovich Yakovlev

The article is devoted to the main work of the Soviet and Russian statesman, legal scholar, Corresponding Member of the Russian Academy of Sciences, Doctor of Law, Professor, Honored Lawyer of the RSFSR Veniamin Fedorovich Yakovlev. This work is the only monographic study of the method of Civil Law in the Russian literature. The article presents the key positions of V. F. Yakovlev’s research on the method of Civil Law and their perception in the Russian doctrine: the connection with the subject of Civil Law, the disclosure of its main feature – the right of ownership, as well as dispositivity. Another distinctive feature of the civil law method is the legal initiative, which is used by civil law as a driving principle in the formation and development of civil legal relations. It is emphasized that V. F. Yakovlev also paid attention to the consideration of the legal equality of subjects as a feature of Civil Law, described in detail the specifics of coercion, sanctions and responsibility in Civil Law, taking into account the specifics of the method of civil law regulation of public relations.

Visual short-term memory for crossed and uncrossed binocular disparities.

Previous work on visual short-term memory (VSTM) has encompassed various stimulus attributes including spatial frequency, color, and contrast, revealing specific time courses and a dependence on stimulus parameters. This study investigates visual short-term memory for binocular depth, using dynamic random dot stereograms (DRDS) featuring disparity planes in front of or behind the plane of fixation. In a delayed match-to-sample paradigm, we employed four distinct reference disparities (17.5', 28.8' either crossed or uncrossed) at two contrast levels (20%, 80%), spanning interstimulus intervals (ISI) of up to 4 s. Test stimuli represented a range of equally spaced values centered around the reference disparity of the ongoing trial. In addition, the impact of a memory masking stimulus was also tested in a separate experiment. Accuracy and point of subjective equality (PSE) served as performance markers. The performance, indicated by the accuracy of responses, was better for smaller reference disparities (±17.5') compared to larger ones (±28'), but both deteriorated as a function of ISI. The PSE demonstrated a consistent shift with increasing ISIs, irrespective of the magnitude of the initial disparity, converging gradually toward the range of 20-22' and deviating from the reference disparity. Notably, the influence of masking stimuli on the PSE was more marked when the mask disparity diverged from the reference value. The findings from our study indicate that the retention of absolute disparity in memory is imprecise, it deteriorates with retention time or due to perturbation by dissimilar masking stimuli. As a result, the memory trace is gradually replaced by a default depth value. This value could potentially signify an optimal point within low-level perceptual memory, however, our results are better explained by perceptual averaging whereby the visual system computationally derives a statistical summary of the presented disparities over time. The latter mechanism would aid in the computation of relative disparity in a dynamically changing environment.

Loudness and preference judgments for noises of a heat pump

An increasing number of heat pumps have recently been installed to replace conventional heating systems to provide more environmentally friendly and energy-efficient indoor heating. Most commonly, air-to-water heat pumps are chosen. However, the sounds of their fan and compressor can lead to noise complaints and can reach the limit of noise emission regulations. To achieve a more pleasant environment, research is conducted to reduce the perceived noise of heat pumps. As part of an interdisciplinary research project, this study aims to investigate the annoyance ratings of a heat pump and characterize them in terms of equivalent loudness and preference penalties. The study uses a two-alternative forced-choice (2AFC) method with a 1-up-1-down rule to measure the point of subjective equality for six stimuli representing different operation states of the investigated device. This experiment aims to identify differences between loudness and preference, and combined with an evaluation of psychoacoustic parameters, its results are used to improve the acoustics of heat pumps and the overall user experience.

Temporal bisection task as a predictor of cognitive deficits.

Evidence suggests that neuropsychiatric symptoms and deficits in attentional control and executive function can impair time discrimination, demonstrating the intricate link between cognitive processes, subjective well-being, and perception of time. However, the relationship between sleep quality and time discrimination remains elusive. This study aimed to understand differences in the temporal bisection task (TBT) performance. We expected that individuals with impaired cognition, executive function, quality of life, or sleep quality would have reduced time sensitivity. At the same time, those with stress, anxiety, or depression would show a shift in the point of subjective equality. Data were collected from 97 female participants (ranging from 20 to 72 years of age) in more than one moment, resulting in 163 measurements used for the analysis. Participants' neuropsychiatric status was assessed using a battery of tests and scales, including the Mini-Mental State Examination (MMSE), the Frontal Assessment Battery (FAB), the World Health Organization Quality of Life Questionnaire (WHOQOL), the Pittsburgh Sleep Quality Index (PSQI), and the Depression, Anxiety, and Stress Scale-21 items (DASS-21). The results showed that attention and executive control significantly affect time discrimination. In addition, the research indicated that better sleep quality is associated with improved time discrimination sensitivity.

Choice of alcohol over a natural reward: an experimental study in light and heavy social drinkers.

A core symptom of alcohol use disorder (AUD) is a progressively increased choice of alcohol over alternative rewards despite negative consequences. Here, we investigated choice between personalized alcohol vs. natural rewards in a laboratory setting, and compared this behavior between non-treatment-seeking heavy drinkers and light social drinkers. 30 light social drinkers (15 men drinking < 15 drinks/week and 15 women drinking < 10 drinks/week) and 30 heavy, non-treatment-seeking drinkers (drinking more than these levels; 15 women). In the Concurrent Choice Alcohol Food (CCAF) task, participants chose between individually tailored images of alcohol and snack rewards and collected points towards the respective reward. To assess cost sensitivity, points associated to the images varied so that they favored alcohol or snack, or were equal, creating three relative point levels. Choice preference for alcohol was strongly correlated with Alcohol Use Disorder Identification Test (AUDIT) scores, supporting the external validity of the choice procedure. Compared to light drinkers, heavy drinkers showed increased choice preference for alcohol, as indicated by a between-group difference in points of subjective equality, a metric that quantifies the relative point level at which alcohol and snacks were equally likely to be chosen. In both groups, choice preference strongly depended on the relative point level of alcohol compared to snacks, suggesting that responding for alcohol in heavy drinkers was sensitive to costs. Our results replicate previous findings of a relationship between self-reported alcohol use and choice preference for alcohol. We also found that choice behavior was strongly dependent on relative cost of alcohol in both groups, although price sensitivity was lower in heavy compared to light drinkers. An increased choice preference for alcohol in heavy drinkers suggests that they attribute a higher relative reinforcing value to alcohol compared to natural rewards.

Older women’s constructions of equality over the lifecourse

Abstract Gender and age are central organising principles of social relations, with socially constructed gendered and age-based norms influencing patterns of social behaviour, power and inequality. Despite recent literature highlighting the importance of subjective measures of equality, including as a significant predictor of wellbeing, there is a gap in studies focused on subjective equality in research on ageing. Drawing on an equality ranking exercise and life herstory interviews with 20 older-aged women (65+) in Aotearoa New Zealand, this article focuses on the intersectionality of age and gender, analysing the ways in which participants constructed their experiences of equality over the lifecourse from their standpoint as older-aged women. The analysis reveals a significant rise in subjective equality from childhood to older age, with more varied responses in childhood and a convergence of responses from adolescence onwards. Participants’ constructions of equality differed: age was the dominant construct of equality women ascribed to their childhood years, while gender inequality came to the fore during their teenage years. In early to mid-adulthood, women found ways to navigate gendered inequality in various life domains, while in older adulthood equality was constructed as freedom and life satisfaction. This trajectory suggests that the frames individuals use to make sense of equality and their personal experiences are not fixed; they are fluid and shift throughout the lifecourse.

Temporal context modulates cross-modality time discrimination: Electrophysiological evidence for supramodal temporal representation

Although the peripheral nervous system lacks a dedicated receptor, the brain processes temporal information through different sensory channels. A critical question is whether temporal information from different sensory modalities at different times forms modality-specific representations or is integrated into a common representation in a supramodal manner. Behavioral studies on temporal memory mixing and the central tendency effect have provided evidence for supramodal temporal representations. We aimed to provide electrophysiological evidence for this proposal by employing a cross-modality time discrimination task combined with electroencephalogram (EEG) recordings. The task maintained a fixed auditory standard duration, whereas the visual comparison duration was randomly selected from the short and long ranges, creating two different audio–visual temporal contexts. The behavioral results showed that the point of subjective equality (PSE) in the short context was significantly lower than that in the long context. The EEG results revealed that the amplitude of the contingent negative variation (CNV) in the short context was significantly higher (more negative) than in the long context in the early stage, while it was lower (more positive) in the later stage. These results suggest that the audiovisual temporal context is integrated with the auditory standard duration to generate a subjective time criterion. Compared with the long context, the subjective time criterion in the short context was shorter, resulting in earlier decision-making and a preceding decrease in CNV. Our study provides electrophysiological evidence that temporal information from different modalities inputted into the brain at different times can form a supramodal temporal representation.

Leveraging Tendon Vibration to Enhance Pseudo-Haptic Perceptions in VR.

Pseudo-haptic techniques are used to modify haptic perception by appropriately changing visual feedback to body movements. Based on the knowledge that tendon vibration can affect our somatosensory perception, this article proposes a method for leveraging tendon vibration to enhance pseudo-haptics during free arm motion. Three experiments were performed to examine the impact of tendon vibration on the range and resolution of pseudo-haptics. The first experiment investigated the effect of tendon vibration on the detection threshold of the discrepancy between visual and physical motion. The results indicated that vibrations applied to the inner tendons of the wrist and elbow increased the threshold, suggesting that tendon vibration can augment the applicable visual motion gain by approximately 13% without users detecting the visual/physical discrepancy. Furthermore, the results demonstrate that tendon vibration acts as noise on haptic motion cues. The second experiment assessed the impact of tendon vibration on the resolution of pseudo-haptics by determining the just noticeable difference in pseudo-weight perception. The results suggested that the tendon vibration does not largely compromise the resolution of pseudo-haptics. The third experiment evaluated the equivalence between the weight perception triggered by tendon vibration and that by visual motion gain, that is, the point of subjective equality. The results revealed that vibration amplifies the weight perception and its effect was equivalent to that obtained using a gain of 0.64 without vibration, implying that the tendon vibration also functions as an additional haptic cue. Our results provide design guidelines and future work for enhancing pseudo-haptics with tendon vibration.

Правовая природа соглашений в сфере пробации

The article analyzes the legal nature of contractual relations in the field of probation. It has been established that the contract in the application of probation acts as an instrument of interaction between public authorities, both among themselves and with organizations of various forms of ownership. It is established that the relations arising in the field of organization and functioning of probation in the Russian Federation presuppose the existence of actual inequality and legal equality of probation subjects. The place of agreements on cooperation in the field of probation in the system of public law contracts has been determined. The place of agreements on cooperation in the field of probation in the system of public law contracts has been determined.

Psychometrics of inertial heading perception.

Inertial self-motion perception is thought to depend primarily on otolith cues. Recent evidence demonstrated that vestibular perceptual thresholds (including inertial heading) are adaptable, suggesting novel clinical approaches for treating perceptual impairments resulting from vestibular disease. Little is known about the psychometric properties of perceptual estimates of inertial heading like test-retest reliability. Here we investigate the psychometric properties of a passive inertial heading perceptual test. Forty-seven healthy subjects participated across two visits, performing in an inertial heading discrimination task. The point of subjective equality (PSE) and thresholds for heading discrimination were identified for the same day and across day tests. Paired t-tests determined if the PSE or thresholds significantly changed and a mixed interclass correlation coefficient (ICC) model examined test-retest reliability. Minimum detectable change (MDC) was calculated for PSE and threshold for heading discrimination. Within a testing session, the heading discrimination PSE score test-retest reliability was good (ICC = 0. 80) and did not change (t(1,36) = -1.23, p = 0.23). Heading discrimination thresholds were moderately reliable (ICC = 0.67) and also stable (t(1,36) = 0.10, p = 0.92). Across testing sessions, heading direction PSE scores were moderately correlated (ICC = 0.59) and stable (t(1,46) = -0.44, p = 0.66). Heading direction thresholds had poor reliability (ICC = 0.03) and were significantly smaller at the second visit (t(1,46) = 2.8, p = 0.008). MDC for heading direction PSE ranged from 6-9 degrees across tests. The current results indicate moderate reliability for heading perception PSE and provide clinical context for interpreting change in inertial vestibular self-motion perception over time or after an intervention.

Exploring virtual reality object perception following sensory-motor interactions with different visuo-haptic collider properties

Interacting with the environment often requires the integration of visual and haptic information. Notably, perceiving external objects depends on how our brain binds sensory inputs into a unitary experience. The feedback provided by objects when we interact (through our movements) with them might then influence our perception. In VR, the interaction with an object can be dissociated by the size of the object itself by means of ‘colliders’ (interactive spaces surrounding the objects). The present study investigates possible after-effects in size discrimination for virtual objects after exposure to a prolonged interaction characterized by visual and haptic incongruencies. A total of 96 participants participated in this virtual reality study. Participants were distributed into four groups, in which they were required to perform a size discrimination task between two cubes before and after 15 min of a visuomotor task involving the interaction with the same virtual cubes. Each group interacted with a different cube where the visual (normal vs. small collider) and the virtual cube's haptic (vibration vs. no vibration) features were manipulated. The quality of interaction (number of touches and trials performed) was used as a dependent variable to investigate the performance in the visuomotor task. To measure bias in size perception, we compared changes in point of subjective equality (PSE) before and after the task in the four groups. The results showed that a small visual collider decreased manipulation performance, regardless of the presence or not of the haptic signal. However, change in PSE was found only in the group exposed to the small visual collider with haptic feedback, leading to increased perception of the cube size. This after-effect was absent in the only visual incongruency condition, suggesting that haptic information and multisensory integration played a crucial role in inducing perceptual changes. The results are discussed considering the recent findings in visual-haptic integration during multisensory information processing in real and virtual environments.

A matter of time: how musical training affects time perception.

Musical training has been linked to changes in early attentional and perceptual processing. Thus, such an altered attentional and perceptual processing has enabled musicians to judge the duration differently than non-musicians. Although these claims seem intriguing, there are many questions that are not addressed yet, for example, how would the performance of musically-trained differ from that of untrained on visual and auditory temporal judgments? Is there any advantage to musically-trained person in temporal processing? To understand these questions, we thus conducted a series of Auditory and Visual Temporal Bisection Tasks on 32 musically-trained and 32 musically-untrained participants. We hypothesized that if music training modulates general sensitivity to temporal dimensions, then the temporal judgments of musically-trained participants would differ from those of untrained participants in both visual and auditory tasks. Each participant performed a total of 140 trials (70 visual and 70 auditory) in two different blocks. For each participant, a Point of Subjective Equality (PSE) was obtained for visual and auditory conditions. The findings revealed a significant modality effect on time perception, with auditory stimuli being consistently overestimated compared to visual stimuli. Surprisingly, the musically-trained group exhibited a tendency to underestimate duration relative to the musically-untrained participants. Although these results may appear counterintuitive at first glance, a detailed analysis indicates that the length of musical training plays a significant role in modulating temporal processing within the musically-trained group.

Constitutional and legal guarantees of the acquisition of private ownership rights to land in Ukraine

The paper raises the problems of acquiring the right to private ownership of land through the free privatization of land plots from reserve lands. Special attention is paid to the need to implement constitutional principles regarding the guarantee of land ownership, acquisition of ownership in accordance with the law, and equality of subjects of land ownership. The shortcomings of the legal provision of the procedure for acquiring ownership of a plot of land specified in the Land Code of Ukraine, which involves an independent search by a person concerned for a free plot of land within the boundaries of state and communal property and the absence of any criteria for determining the procedure for the allocation of a particular plot of land, have been revealed. The issue of ensuring the principle of equality of the subject of property rights before the law in the process of realizing the right to free privatization of the land plot is raised. Scientific approaches are being developed, according to which the exercise of the right to own land by state authorities and local self-government bodies has a slightly different legal nature and content than that of private owners. The mandatory procedure for the implementation of the relevant right by state authorities and local self-government bodies, which must ensure the right of citizens to free access to information about such a plot, as well as the specified mechanism for its free transfer to the citizen, is substantiated. Based on the results of the study, the need for further improvement of the legislative mechanism for acquiring the right to private ownership of land is substantiated, taking into account the analyzed constitutional principles. Among the key tasks of the legislative support of the relevant procedures, the following are highlighted: land inventory and filling of the state land cadastre at the expense of local budgets in order to determine the free land that is in reserve; determination of criteria and order of possible distribution of land, taking into account the characteristics of specific administrative-territorial units; review of the jurisdiction of consideration of the relevant category of cases in the direction of administrative jurisdiction.

APPLICATION OF BANK DEPOSIT INSURANCE LEGISLATION: MAIN ASPECTS

The article highlights the special relevance of the legal study of the bank deposit insurance system. The authors have identified the main trends in the historical development of the bank deposit insurance system, which are generally of positive importance. The article also analyzes the main problems of legislation and law enforcement practice in the field of bank deposit insurance. The conclusion is formulated that the legitimate interest of depositors should be protected primarily, while the established judicial practice in some cases indicates the opposite. In addition, the legislation on insurance of bank deposits violates the principle of equality of subjects of civil law. This situation leads to a drop in the level of depositors' trust and is an obstacle to the effective implementation of the bank deposit insurance system.

Ensuring equality in the field of labor is one of the fundamental tasks of the state

Guaranteeing rights and freedoms for citizens and forming new, equal relations in society are currently one of the main directions of our state's activity. Because equality is one of those fundamental values that must be enshrined in legislation and implemented in practice in a state that is declared legal, social, and democratic. The purpose of the article is to consider the issue of ensuring equality of rights and opportunities and their impact on a person's ability to work in today's realities. After all, in practice in the field of labor there are many cases of violation of the principle of equality, when employees are actually deprived of the opportunity to protect their rights in case of illegal refusal to accept employment and in case of dismissal due to the fact that employers do not provide an official refusal indicating the valid reasons for refusal work or try to formulate the reasons for dismissal at the employee's own will or with the consent of the parties, which causes concern in view of their massiveness, especially today, when the country is in a state of war against the Russian aggressor. Summarizing the conducted research, it is stated that today Ukraine is already on the way to ensure equal rights of workers and implementation of norms, principles and provisions enshrined in international legal acts in the field under consideration. This is evidenced by the adoption of legislative acts, which will contribute to bringing domestic legislation into compliance with the legislation of the European Union, the practice of the International Labor Organization and will have a positive impact on the market environment. At the same time, it was noted that during the reform of domestic labor legislation, in particular, it is necessary to prevent the narrowing of the existing rights and guarantees of employees, to provide legal instruments that will contribute to the implementation of the principle of equality in the field of labor, in particular, the equality of regulation of the status of subjects of labor law, equal protection labor rights and interests of employees and employers, equality of subjects of labor law when labor relations arise.

Altered mechanisms of adaptation in social anxiety: differences in adapting to positive versus negative emotional faces

ABSTRACT Social anxiety is characterised by fear of negative evaluation and negative perceptual biases; however, the cognitive mechanisms underlying these negative biases are not well understood. We investigated a possible mechanism which could maintain negative biases: altered adaptation to emotional faces. Heightened sensitivity to negative emotions could result from weakened adaptation to negative emotions, strengthened adaptation to positive emotions, or both mechanisms. We measured adaptation from repeated exposure to either positive or negative emotional faces, in individuals high versus low in social anxiety. We quantified adaptation strength by calculating the point of subjective equality (PSE) before and after adaptation for each participant. We hypothesised: (1) weaker adaptation to angry vs happy faces in individuals high in social anxiety, (2) no difference in adaptation to angry vs happy faces in individuals low in social anxiety, and (3) no difference in adaptation to sad vs happy faces in individuals high in social anxiety. Our results revealed a weaker adaptation to angry compared to happy faces in individuals high in social anxiety (Experiment 1), with no such difference in individuals low in social anxiety (Experiment 1), and no difference in adaptation strength to sad vs happy faces in individuals high in social anxiety (Experiment 2).

Finding the ratio of perceived duration between tones with flat and percussive amplitude envelopes

The extensive literature on duration assessment generally uses tones with clear onsets and offsets. However, simplistic sounds can fail to evoke the same processes used when listening to sounds with time varying amplitude envelopes (Schutz &amp; Gillard, 2020). To facilitate future research on the duration assessment of time varying tones, here we explore the ratio at which constant amplitude ‘flat’ and varying amplitude ‘percussive’ tones are perceived as the same duration. We will use an adaptive staircase procedure, in which flat and percussive tones are presented in pairs and participants state which tone sounded longer in duration. Each response changes the duration difference on subsequent trials and continues until responses converge around a specific point, with convergence defined as four consecutive reversals in response direction. One instance of these trials constitutes a single staircase; we will then calculate the millisecond point of subjective equality between flat and percussive tones by finding the average point of convergence between multiple, interleaved staircases. Beyond providing guidance on stimulus durations for studies comparing amplitude envelope, we aim to shed light on the process of duration assessment in sounds with time-varying amplitude envelopes.

Spatial tactile localization depends on sensorimotor binding: preliminary evidence from virtual reality.

Our brain continuously maps our body in space. It has been suggested that at least two main frames of reference are used to process somatosensory stimuli presented on our own body: the anatomical frame of reference (based on the somatotopic representation of our body in the somatosensory cortex) and the spatial frame of reference (where body parts are mapped in external space). Interestingly, a mismatch between somatotopic and spatial information significantly affects the processing of bodily information, as demonstrated by the "crossing hand" effect. However, it is not clear if this impairment occurs not only when the conflict between these frames of reference is determined by a static change in the body position (e.g., by crossing the hands) but also when new associations between motor and sensory responses are artificially created (e.g., by presenting feedback stimuli on a side of the body that is not involved in the movement). In the present study, 16 participants performed a temporal order judgment task before and after a congruent or incongruent visual-tactile-motor- task in virtual reality. During the VR task, participants had to move a cube using a virtual stick. In the congruent condition, the haptic feedback during the interaction with the cube was provided on the right hand (the one used to control the stick). In the incongruent condition, the haptic feedback was provided to the contralateral hand, simulating a sort of 'active' crossed feedback during the interaction. Using a psychophysical approach, the point of subjective equality (or PSE, i.e., the probability of responding left or right to the first stimulus in the sequence in 50% of the cases) and the JND (accuracy) were calculated for both conditions, before and after the VR-task. After the VR task, compared to the baseline condition, the PSE shifted toward the hand that received the haptic feedback during the interaction (toward the right hand for the congruent condition and toward the left hand for the incongruent condition). This study demonstrated the possibility of inducing spatial biases in the processing of bodily information by modulating the sensory-motor interaction between stimuli in virtual environments (while keeping constant the actual position of the body in space).

Effects of binocular disparity on binocular luminance combination.

This study aimed to examine the effects of binocular disparity on binocular combination of brightness information coming from luminance increments and decrements. The point of subjective equality was determined by asking the observers to judge which stimulus appeared brighter-a bar stimulus with variable disparity or another stimulus with zero disparity. For the bar stimulus, the interocular luminance ratio was varied to trace an equal brightness curve. Binocular disparity had no effect on luminance increments presented on a gray or black background. In contrast, when luminance decrements were presented on a gray background, non-zero disparities elevated points of subjective equality for stimuli with interocular luminance differences. This means that the binocular brightness combination of the two monocular signals shifted from winner-take-all summation toward linear averaging. It has been argued that this effect may be caused by non-zero binocular disparities attenuating interocular suppression, which is deemed to operate normally with zero disparity.

Texture congruence modulates perceptual bias but not sensitivity to visuotactile stimulation during the rubber hand illusion.

The sense of body ownership is the feeling that one's body belongs to oneself. To study body ownership, researchers use bodily illusions, such as the rubber hand illusion (RHI), which involves experiencing a visible rubber hand as part of one's body when the rubber hand is stroked simultaneously with the hidden real hand. The RHI is based on a combination of vision, touch, and proprioceptive information following the principles of multisensory integration. It has been posited that texture incongruence between rubber hand and real hand weakens the RHI, but the underlying mechanisms remain poorly understood. To investigate this, we recently developed a novel psychophysical RHI paradigm. Based on fitting psychometric functions, we discovered the RHI resulted in shifts in the point of subjective equality when the rubber hand and the real hand were stroked with matching materials. We analysed these datasets further by using signal detection theory analysis, which distinguishes between the participants' sensitivity to visuotactile stimulation and the associated perceptual bias. We found that texture incongruence influences the RHI's perceptual bias but not its sensitivity to visuotactile stimulation. We observed that the texture congruence bias effect was the strongest in shorter visuotactile asynchronies (50-100 ms) and weaker in longer asynchronies (200 ms). These results suggest texture-related perceptual bias is most prominent when the illusion's sensitivity is at its lowest. Our findings shed light on the intricate interactions between top-down and bottom-up processes in body ownership, the links between body ownership and multisensory integration, and the impact of texture congruence on the RHI.
