Empirical Analysis of Opportunism Based on Data on University Students of Different Courses

The article is devoted to the New Institutional analysis of the factors of opportunism among students of different courses. The analysis is based on a survey in which 231 students from the Higher School of Economics and other Russian universities took part from February to May 2021. Econometric modeling is based on Latent class analysis, which allows the identification of unobservable groups based on the observed categorical variables presented. One of the main findings of the research is that fourth year students are less prone to opportunism than first, second and third year students. This can be explained by the higher opportunity costs of cheating among fourth year students and their greater independence, primarily financial. In addition, students who are motivated primarily to obtain knowledge (mastery) show a lesser inclination towards opportunism compared with students whose main motive is the degree (performance). Furthermore, a higher level of rationality, both in a general sense and in relation to budget planning, is reflected in a greater tendency to dishonest behavior. Finally, more honest behavior outside the university is combined with more dishonest academic behavior. The latter can be explained by the fact that it is psychologically more difficult to commit an immoral act in relation to a loved one than to do so in an academic environment, when you deceive a not personally familiar person and not even a specific person. Thus, on the basis of the analysis carried out, it can be understood under what conditions the student environment will be characterized by a higher propensity for opportunism and, accordingly, a lower rate of human capital accumulation.

Simulation-based learning shapes real-life attitudes

Humans can vividly simulate hypothetical experiences. This ability draws on our memories (e.g., of familiar people and locations) to construct imaginings that resemble real-life events (e.g., of meeting a person at a location). Here, we examine the hypothesis that we also learn from such simulated episodes much like from actual experiences. Specifically, we show that the mere simulation of meeting a familiar person (unconditioned stimulus; US) at a known location (conditioned stimulus; CS) changes how people value the location. We provide key evidence that this simulation-based learning strengthens pre-existing CS-US associations and that it leads to a transfer of valence from the US to the CS. The data thus highlight a mechanism by which we learn from simulated experiences.

Horse Behavior towards Familiar and Unfamiliar Humans: Implications for Equine-Assisted Services

While human benefits of animal-assisted therapy programs have been documented, relatively little research has been conducted on behavioral factors that predict a successful equine-assisted services (EAS) horse. This study compares the behavior of experienced and non-experienced EAS horses as well as horses selected for future EAS work in a series of sociability and temperament tests. No significant differences were found between experienced and non-experienced horses in the sociability measures or for most of the temperament tests; however, significant differences were found between groups in the brushing test, with non-experienced horses showing more affiliative behaviors towards the familiar handler and unfamiliar persons. No significant differences were found between selected and non-selected horses in the temperament tests. However, non-selected horses were found to show significantly more affiliative behaviors towards a familiar person during a sociability test compared with selected horses. These findings suggest that the social behavior and temperament of EAS horses may not be significantly different from other available horses not selected for EAS work. Instead, these decisions may primarily reflect subjective impressions of fit. Interestingly, on measures where significant differences were identified, the horses not actively engaged in or selected for therapy were the ones that showed greater affiliative responses to familiar and unfamiliar humans. Reasons for why this may be, as well as future directions in EAS selection, are discussed.

Eye-Tracking Reveals a Role of Oxytocin in Attention Allocation Towards Familiar Faces

Visual attention directed towards the eye-region of a face emerges rapidly, even before conscious awareness, and regulates social interactions in terms of approach versus avoidance. Current perspectives on the neuroendocrine substrates of this behavioral regulation highlight a role of the peptide hormone oxytocin (OXT), but it remains unclear whether the facilitating effects of OXT vary as a function of facial familiarity. Here, a total of 73 healthy participants was enrolled in an eye-tracking experiment specifically designed to test whether intranasal OXT (24 IU) augments gaze duration toward the eye-region across four different face categories: the participants’ own face, the face of their romantic partner, the face of a familiar person (close friend) or an unfamiliar person (a stranger). We found that OXT treatment induced a tendency to spend more time looking into the eyes of familiar persons (partner and close friend) as compared to placebo. This effect was not evident in the self and unfamiliar conditions. Independent of treatment, volunteers scoring high on autistic-like traits (AQ-high) spent less time looking at the eyes of all faces except their partner. Collectively, our results show that the OXT system is involved in facilitating an attentional bias towards the eye region of familiar faces, which convey safety and support, especially in anxious contexts. In contrast, autistic-like traits were associated with reduced attention to the eye region of a face regardless of familiarity and OXT-treatment.

Targeted Memory Reactivation of Face-Name Learning Depends on Ample and Undisturbed Slow-Wave Sleep

Face memory, including the ability to recall the name of a familiar person, is often crucial in social interactions, and like many other memory functions, it may rely on sleep. We investigated whether targeted memory reactivation during sleep could improve associative and perceptual aspects of face memory. Participants studied 80 face-name pairs, and then a subset of spoken names was presented unobtrusively during a daytime nap. This reactivation preferentially improved recall for those face-name pairs, as modulated by two factors related to sleep quality. That is, the memory benefit was positively correlated with the duration of stage N3 sleep (slow-wave sleep) and with the extent to which cues presented during SWS did not produce a sleep disruption indexed by increased alpha-band electroencephalographic activity in the 5 seconds after a cue. Follow-up analyses showed that a memory benefit from presenting spoken names during sleep was evident in participants with high amounts of SWS or with low amounts of sleep disruption. We conclude that sleep reactivation can strengthen memory for specific face-name associations and that the effectiveness of reactivation depends on uninterrupted N3 sleep.

Exploring the dog–human relationship by combining fMRI, eye-tracking and behavioural measures

Behavioural studies revealed that the dog–human relationship resembles the human mother–child bond, but the underlying mechanisms remain unclear. Here, we report the results of a multi-method approach combining fMRI (N = 17), eye-tracking (N = 15), and behavioural preference tests (N = 24) to explore the engagement of an attachment-like system in dogs seeing human faces. We presented morph videos of the caregiver, a familiar person, and a stranger showing either happy or angry facial expressions. Regardless of emotion, viewing the caregiver activated brain regions associated with emotion and attachment processing in humans. In contrast, the stranger elicited activation mainly in brain regions related to visual and motor processing, and the familiar person relatively weak activations overall. While the majority of happy stimuli led to increased activation of the caudate nucleus associated with reward processing, angry stimuli led to activations in limbic regions. Both the eye-tracking and preference test data supported the superior role of the caregiver’s face and were in line with the findings from the fMRI experiment. While preliminary, these findings indicate that cutting across different levels, from brain to behaviour, can provide novel and converging insights into the engagement of the putative attachment system when dogs interact with humans.

Evacuation Guidance Design: An Experimental Study Based on Eye Tracking Devices

It is a crucial issue whether evacuees follow the evacuation guidance during evacuation. Good evacuation guidance is necessary to be designed to help the evacuees follow the guidance. In this paper, evacuation experiments based on wearable eye tracking devices were carried out to study the design effect of the evacuation guidance. Three factors were considered in these experiments: 1) the position of the evacuation guidance; 2) follow guidance or follow other evacuees; 3) follow a stranger or a familiar person. The results show that more participants noticed the guidance with low position and ground position than the guidance with up position. The evacuees intend to follow others rather than to follow the guidance, i.e. most evacuees act as “follower”. Eye tracking evacuation experiments can also be used to test the effectiveness of evacuation guidance signs.

PERTIMBANGAN HAKIM DALAM MENENTUKAN HAK ASUH ANAK AKIBAT PERCERAIAN AGAMA HINDU DI BALI

The prominent legal issues in balinese law can be classified in two problems, inheritance and purusa ( descendant ), purusa is an inherent status (comonly for male) after marriage. If there is later a divorce, the judge must consider the decision in applying the law that was enforced in deciding the divorce case. Referring to Balinese customary law, when there is a divorce, the child's custody will fall on the purusa / father because the child will become a descendant of the father's family, whereas in the Decision of the Supreme Court of the Republic of Indonesia number: 126K / Pdt. / 2001 dated August 28, 2003 states that "If the father and mother divorce, then the care of the underage child is left to the closest and familiar person to the child, namely the mother". Therefore, the basis for weighing judges in determining custody of children in Hindu religious divorce in Balinese customary law is to combine two legal mechanisms between customary law and national law, where from the aspect of Balinese customary law which adheres to the purusa system, the right is on the purusa party but because the child is still underage, the child is under the mother's care until the child become an adult, and mother can not prevent the child to exercising rights and obligations in the father's family as purusa.

How does familiarity with a person affect trait ratings?

From only a single spoken word, listeners can form a wealth of first impressions of a person’s character traits and personality based on their voice. However, due to the substantial within-person variability in voices, these trait judgements are likely to be highly stimulus-dependent for unfamiliar voices: the same person may sound very trustworthy in one recording but less trustworthy in another. How trait judgements may change when listeners are familiar with a voice is unclear: Are listeners who are familiar with the voices as susceptible to the effects of within-person variability? Does the semantic knowledge listeners have about a familiar person influence their judgements? In the current study, we aimed to empirically test the effect of familiarity on listeners’ trait judgements from variable voices, by tracking how first impressions may differ from second (or “lasting”) impressions. For this purpose, we conducted a series of 3 experiments in which we contrasted trait judgments for listeners who were familiar with a set of voices – either through lab-based training or through watching a TV show – with listeners who were unfamiliar with the voices. We predicted that familiarity would reduce variability in trait judgements for variable voice recordings from the same identity (cf. Mileva, Kramer & Burton, 2019 for faces). However, across the 3 studies and two types of measures to assess variability, we found no compelling evidence to suggest that trait impressions were systematically affected by familiarity.

An Acoustic-Based Smart Home System for People Suffering from Dementia

Aging-in-place can reduce the progress of dementia syndrome and improve the quality of life of the sufferers and their families. Taking into consideration the fact that numerous neurological research results suggest the use of sound as a stimulus for empowering the memory of the sufferer, an innovative information home support system for people suffering from dementia is proposed. The innovation of the proposed system is found in its application, that is to integrate a home system for assisting with person recognition via a sound-based memory aid service. Furthermore, the system addresses the needs of people suffering from dementia to recognize their familiars and have better interaction and collaboration, without the need for training. The system offers a ubiquitous recognition system, using smart devices like smart-phones or smart-wristbands. When a familiar person is detected in the house, then a sound is reproduced on the smart speakers, in order to stimulate the sufferer’s memory. The system identified all users and reproduced the appropriate sound in 100% of the cases. To the best of the authors’ knowledge, this is the first system of its kind for assisting person recognition via sound ever reported in the literature.
