Psychological effects of human interaction in mahjong: A heart-rate study

Summary. Introduction: The problem of human interaction with the environment acquires special importance nowadays. Significant migration processes observed in the last decade have become global, thus necessitating studies of the mechanisms of human adaptation to new environmental conditions. Our objective was to study age-related changes in functional indices of the cardiovascular system in adolescents between 11 and 17 years of age, born in Magadan in the first to third generation of Caucasians who had migrated to this city. Material and methods: In all, 1,442 school-age adolescents were examined including 809 boys and 633 girls. The main anthropometric parameters (body weight, kg, and height, cm) were measured and cardiac hemodynamics was determined at rest in the sitting position by volumetric compression oscillometry using a non-invasive hard- and software unit for central hemodynamic study. Results: Significantly higher values of cardiac output and stroke volume prevailed in boys of all age groups. The boys aged 14-17 years also demonstrated higher values of systolic blood pressure and left ventricular power output compared to girls. At the same time, the girls had higher age-specific indices of the heart rate, diastolic blood pressure, and total peripheral resistance. Conclusion: We established that the highest rates of cardiovascular functional development occur during puberty in 11 to 16-year-old boys and 11 to 13-year-old girls. Our findings showed that only 70.2 % to 77.2 % of the boys and 75.1 % to 80.2 % of the girls had blood pressure and heart rate readings within the age norm. Prehypertension was registered in 11.3 % and 10.3 % while hypertension was observed in 11.5 % and 9.5 % of the examined boys and girls, respectively. Tachycardia at rest was noted in 18 % of the boys and 20.2 % of the girls.

Two Phases

The heart rate variability (HRV) parameters of dairy cows were monitored during parlour (PARL) and the later installed automatic (AMS) milking on a small-scale commercial dairy farm in Hungary. The aim of the study was to assess stress in relation to the type of milking and the frequency of human interaction. Parlour milking involved regular moving and crowding of the animals with frequent human interaction, which were much less frequent in automatic milking. The first phase of the study was conducted prior to the changeover [n = 27] and the second two months afterwards [n = 19 (of the cows from the first phase)]. Heart rate (HR) was recorded by the Polar RS800 CX recording system. HRV parameters indicative of sympathovagal balance were calculated for periods of lying and standing in the barn, waiting before milking and milking, respectively. Morning and evening faecal glucocorticoid concentrations were also measured. Fear of humans was tested by an avoidance distance test. Baseline HRV parameters showed no difference (P > 0.05) between the two systems. In the periods before, during and after milking a higher sympathetic tone was detected in cows in the PARL phase. Mean faecal glucocorticoid concentrations were higher at the time of parlour milking. The avoidance distance did not differ between the two phases. The results suggest that automatic milking might be less stressful for cows than parlour milking, possibly due to the shorter duration of restraint after milking and the less frequent human interaction.

Entire Experiment

This study investigated the physioacoustic chair's, i.e., an application of low-frequency sound waves, possible psychological effects with respect to deductive thinking and creativity as well as its possible effect on heart rate. Subjects, 21 men and 21 women, were randomly assigned in equal numbers to three groups: a control group, a placebo group, i.e., a group who believed that they underwent a physioacoustic treatment program which they however did not undergo, and a physioacousdc treatment group. After manipulation, subjects were required to take three psychological tests (measuring fluency and originality, preconscious thinking, and deductive thinking) in random order. During the entire experiment, subjects' heart rates were registered every minute. Analysis showed no significant differences among the groups with respect to psychological effects or to heart rate. The results were interpreted to mean that the physioacousdc chair provides a form of relaxation which does not produce effects on the creative process.

Psychological Dimensions

Talking about design, most discussions circulate around physical objects or products, around their invention, development, production and marketing. While most modern design approaches do also cover questions pertaining to human interaction, e.g. within user- or human-centred design philosophies, a systematic and fundamental conception of the role and implications that human perception and emo-cognitive processing take with regard to designing physical goods is lacking. Under the umbrella term ‘Psychology of Design’, I will develop and elaborate on psychological dimensions that are highly relevant to the optimization and evaluation of design. I propagate a general psychological turn in design theory and practice in order to purposefully include not only the top-down processes triggered by context, framing, expectation, knowledge or habituation but also the psychological effects of Gestalt and Zeitgeist. Such psychological effects have the potential to determine whether the very same physical design will be aesthetically appreciated, desired, loved or rejected in the end. Psychology of design has a tremendous influence on the success and sustainability of design by triggering associations and displaying demand characteristics in a multimodal way. The paper is based on fundamental psychological theories and empirical evidences which are linked to applied examples from the world of art and design.

Research Highlights: This study demonstrated that viewing forest landscapes induced physical and mental health benefits on young women. Background and Objectives: The health-promoting effects of spending time in forests have received increasing attention; however, there is a lack of evidence-based research investigating the effects of spending time in forests on women. This study aimed to evaluate the physiological and psychological effects of viewing forest landscapes on young women. Materials and Methods: The experiments were conducted in six forests and six city areas and included 65 women (mean age, 21.0 ± 1.3 years). Participants viewed a forest and a city area for 15 min, during which their heart rate variability and heart rate were measured continuously. Blood pressure and pulse rate were measured before and after the viewing. After the viewing, participants’ psychological responses were assessed using the modified semantic differential method, Profile of Mood States (POMS), and the State–Trait Anxiety Inventory (STAI). Results: Compared with viewing city areas, viewing forest landscapes was associated with significantly higher parasympathetic nervous activity and lower sympathetic nervous activity and heart rate. Moreover, scores of the comfortable, relaxed, and natural parameters and vigor subscales of POMS were significantly higher with forest viewing. The scores of negative feelings, such as tension–anxiety, depression–dejection, anger–hostility, fatigue, and confusion, were significantly lower, as were scores for the total mood disturbance observed using POMS and the anxiety dimension observed using STAI. Conclusions: Viewing forest landscapes resulted in physiological and psychological relaxations in young women.
