Differing Dynamics of Intrapersonal and Interpersonal Coordination: Two-finger and Four-Finger Tapping Experiments

Finger-tapping experiments were conducted to examine whether the dynamics of intrapersonal and interpersonal coordination systems can be described equally by the Haken—Kelso—Bunz model, which describes inter-limb coordination dynamics. This article reports the results of finger-tapping experiments conducted in both systems. Two within-subject factors were investigated: the phase mode and the number of fingers. In the intrapersonal experiment (Experiment 1), the participants were asked to tap, paced by a gradually hastening auditory metronome, looking at their fingers moving, using the index finger in the two finger condition, or the index and middle finger in the four-finger condition. In the interpersonal experiment (Experiment 2), pairs of participants performed the task while each participant used the outside hand, tapping with the index finger in the two finger condition, or the index and middle finger in the four-finger condition. Some results did not agree with the HKB model predictions. First, from Experiment 1, no significant difference was observed in the movement stability between the in-phase and anti-phase modes in the two finger condition. Second, from Experiment 2, no significant difference was found in the movement stability between the in-phase and anti-phase mode in the four-finger condition. From these findings, different coordination dynamics were inferred between intrapersonal and interpersonal coordination systems against prediction from the previous studies. Results were discussed according to differences between intrapersonal and interpersonal coordination systems in the availability of perceptual information and the complexity in the interaction between limbs derived from a nested structure.     

Validating the German version of the Quality of Relationship Inventory: confirming the three-factor structure and report of psychometric properties

Research on psychosocial influences such as relationship characteristics has received increased attention in the clinical as well as social-psychological field. Several studies demonstrated that the quality of relationships, in particular with respect to the perceived support within intimate relationships, profoundly affects individuals' mental and physical health. There is, however, a limited choice of valid and internationally known assessments of relationship quality in Germany. We report the validation of the German version of the Quality of Relationships Inventory (QRI). First, we evaluated its factor structure in a representative German sample of 1.494 participants by means of confirmatory factor analysis. Our findings support the previously proposed three-factor structure. Second, importance and satisfaction with different relationship domains (family/children and relationship/sexuality) were linked with the QRI scales, demonstrating high construct validity. Finally, we report sex and age differences regarding the perceived relationship support, conflict and depth in our German sample. In conclusion, the QRI is a reliable and valid measurement to assess social support in romantic relationships in the German population.     

Negative relationships in the family-of-origin predict attenuated cortisol in emerging adults

Negative childhood family environments have been associated with stress-related physical and psychological health consequences across the lifespan. The present study examined the relation between adverse relationships in the family of origin and physiological stress response, as measured by salivary cortisol, in emerging adulthood. Seventy-six university students (age range = 18-22) selected from intact married families-of-origin characterized by either negative (n = 39) or positive (n = 37) relationship quality engaged in a challenging role play task. Results from multilevel models indicated that those from negative families exhibited significantly lower salivary cortisol across the task than those from positive families. This relation did not change in strength or direction after controlling for experiences with abuse or recent anxiety or depressive symptoms. These findings suggest the significance of early family relationships on the long-term activity of the HPA axis.     

Infidelity,jealousy, and wife abuse among Tsimane forager–farmers: testing evolutionary hypotheses of marital conflict

The role of men's jealousy over a wife's infidelity in precipitating marital conflict and wife abuse is well documented. The role of women's jealousy over a husband's infidelity has received little attention, which is puzzling given high potential costs to women of withdrawal of paternal investment. We address this gap by investigating marital conflict and wife abuse among Tsimane forager–farmers of Bolivia. We test predictions derived from male jealousy and paternal disinvestment hypotheses, which consider threats and consequences of infidelity by women (male jealousy hypothesis) and men (paternal disinvestment hypothesis). The paternal disinvestment hypothesis proposes that wife abuse is employed by husbands to limit wives' mate retention effort and maintain men's opportunities to pursue extrapair sexual relationships. Interviews were conducted among husbands and wives in the same marriages using a combination of open-ended and structured items. Spouses agree that the most frequently reported type of marital argument is women's jealousy over a husband's infidelity (N=266 arguments). Roughly 60% of abusive events occurred during arguments over men's diversion of household resources (N=124 abusive events). In multivariate analyses, likelihood of wife abuse is greater in marriages where husbands have affairs, where wives are younger, and where spouses spend more time apart (N=60 husbands, 71 wives). While we find strong support for both male jealousy and paternal disinvestment hypotheses, it is men's infidelity, not women's, that precipitates most instances of marital conflict and wife abuse. We conclude that men's aggression towards their wives facilitates men's diversion of family resources for their selfish interests.     

The relationship between job satisfaction and job factors in industrial work design: a case study of the automotive industries in Malaysia

A survey was conducted to investigate the relationship between job satisfaction and job factors that affect work design in two automotives manufacturing companies in Malaysia. A set of multiple choices questionnaires was developed and data were collected by interviewing the employees at the production plant. Hundred and seventy male subjects between the ages of 18 to 40 years with the mean age of 26.8 and SD of 5.3 years and mean work experience of 6.5 and SD of 4.9 years took part in the survey. The survey focused on job factors, i.e. skill variety, task identity, task significance, autonomy and feedback. The results support the previous findings that job factors are significantly correlated to job satisfaction. Furthermore, it also highlights the significant influence of age, work experience and marital status.     

The implications of changing hormonal contraceptive use after relationship formation

Modern-day environments differ drastically from those in which humans evolved, which likely has important implications for human mating psychology. Particularly notable is the modern advancement of hormonal contraceptives (HCs), which alter the natural hormones of the many women who use them. According to the HC congruency hypothesis, HCs alter sex hormones and brain processes that are linked to numerous relationship preferences. In light of work suggesting such preferences play an important role in relationship evaluations, changing HC use during a long-term relationship (relative to use at relationship formation) should impact women's relationships. We used data from two independent longitudinal studies of 203 newlywed couples to address this possibility. Results demonstrated that wives reported lower sexual satisfaction (but not marital satisfaction) when their HC use was incongruent (versus congruent) with their use at relationship formation. These findings provide preliminary support for the HC congruency hypothesis, though we also broaden our theoretical framework to offer methodological recommendations for future research.     

Work and Family Characteristics as Predictors of Early Retirement in Married Men and Women

This study presents an integrative model of early retirement using data from the Wisconsin Longitudinal Study. The model extends prior work by incorporating work-family conflict to capture the interaction between the work and family domains and by assuming proximal and distal predictors of early retirement. More precisely, the model suggests that family and job demands and resources predict family-to-work and work-to-family conflict, respectively. All of these factors are presumed to have only indirect effects on retirement timing via the intervening effect of quality of life measures, that is, marital satisfaction, job satisfaction and health. The authors assume that these three factors constitute predictors of early retirement in addition to socioeconomic status and the availability of a pension plan and health insurance. The model was tested with structural equation modeling techniques, and the results were supportive. Therefore, the proposed model offers a general framework for the integration of previous research findings.     

Unconscious components of the psychophysiological reactions of the participants of the experiment with 520-day isolation

Six participants of Mars-500 were examined to obtain information about intrapersonal conflicts and life spheres with high emotional tension associated with them by participation in an experiment with prolonged group isolation. The investigation was performed using operational analogy-based neurosemantic psychodiagnostics, with the subconscious regarded as a semantic filter with unstructured semantic information at the input and information structured by the inner world content at the output. The results shed light on the semantic structure of the subjective experience and functioning of protective mechanisms, as well as organizational levels and modality of emotional experience. Before and after a 520-day isolation, all the participants were shown to have intrapersonal conflicts and high emotional tension in the socio-professional sphere, caused by the family/sexual and interpersonal relations and self-assessment, and concerns about life and health. On completion of the isolation, the psychoemotional tension was reduced in interpersonal relations and increased in family/sexual ones.     

Parents' testosterone and children's perception of parent-child relationship quality

We examine the link between parental testosterone and children's perceptions of their relationship with their mother and father. Using data from 352 predominantly white working and middle class families, we find no direct link between mother's and father's testosterone and parent–child closeness. However, the association between mothers' testosterone and mother–child closeness appears to be influenced by the quality of two other family relationships. When father's marital satisfaction is low, mothers with high testosterone have a poorer relationship with their children. And, when fathers report low levels of intimacy with their children, high testosterone women have a poorer relationship with their children. No comparable associations were observed among fathers.     

High paternal testosterone may protect against postpartum depressive symptoms in fathers,but confer risk to mothers and children

Following the birth of an infant, decreases in testosterone and increases in depressive symptoms have been observed in fathers. Paternal testosterone may reflect fathers' investment in pair-bonding and paternal caregiving and, as such, may be associated with maternal and familial well-being. This study tests associations between paternal testosterone, paternal and maternal postpartum depressive symptoms, and subsequent family functioning.Within 149 couples, fathers provided testosterone samples when infants were approximately nine months old and both parents reported on postpartum depressive symptoms at two, nine, and 15 months postpartum. Fathers with lower aggregate testosterone reported more depressive symptoms at two and nine months postpartum. Mothers whose partners had higher evening testosterone reported more depressive symptoms at nine and 15 months postpartum. Maternal relationship satisfaction mediated this effect, such that mothers with higher testosterone partners reported more relationship dissatisfaction, which in turn predicted more maternal depressive symptoms. Higher paternal testosterone and paternal depressive symptoms at nine months postpartum each independently predicted greater fathering stress at 15 months postpartum. Higher paternal testosterone also predicted more mother-reported intimate partner aggression at 15 months postpartum. In addition to linear relationships between testosterone and depression, curvilinear relationships emerged such that fathers with both low and high testosterone at nine months postpartum reported more subsequent (15-month) depressive symptoms and fathering stress.In conclusion, whereas higher paternal testosterone may protect against paternal depression, it contributed to maternal distress and suboptimal family outcomes in our sample. Interventions that supplement or alter men's testosterone may have unintended consequences for family well-being.     

Conjoint Psychotherapy of Marital Pairs

Many traditional concepts are being challenged in contemporary psychiatric practice, including the classical “one-to-one” relationship of individual psychotherapy. Where the patient''s presenting difficulties include significant inability to function or feel happy in the marital role, the technique of conjoint psychotherapy (having both partners treated simultaneously by the same doctor) may be indicated. Conjoint therapy is envisaged as a continuum, embracing a considerable range of situations where it is sound practice to see husband and wife together. The treatment plan has three stages: complaint, clarification, and compromise, each of which presents specific features and pitfalls. Emphasis is placed on dealing with individual psychopathology of each partner, both per se and in relation to the marital situation. Results to date suggest that conjoint treatment represents a promising therapeutic modality. Even in cases where individual psychopathology cannot fully be resolved, certain plateaus of satisfaction may be attained as communication improves.     

Family background characteristics and relationship satisfaction in a native community in Canada

Abstract

Using data collected from a Native Canadian community by Embree (1993), we examine the influence of personal and family background characteristics on satisfaction with spousal relationships, both legal marriages and cohabitations. Of special interest are the quality of relationships with parents while growing up, alcohol abuse by the parent(s), and the experience of sexual abuse during childhood. Personal traits such as age, sex, and gender role attitudes and the respondent's own drinking behavior are also considered. Path analytic techniques model both the direct effects of independent variables on relationship satisfaction as well as the role of personal consumption of alcohol as an intervening variable in level of satisfaction with a relationship. The results of the analysis indicate that personal consumption of alcohol and the experience of sexual abuse during childhood are the best direct predictors of level of satisfaction with the current relationship, with higher alcohol consumption and experience of sexual abuse related to lower satisfaction. Age also has a significant direct, though smaller, positive influence on relationship satisfaction. Sexual abuse and the respondent's sex are also linked to level of satisfaction through personal alcohol consumption. With personal alcohol use, both the respondent's sex and the experience of sexual abuse during childhood have a significant effect, with males and those sexually abused as children reporting higher levels of alcohol consumption. The socialization explanation of the intergenerational consequences of parental behavior argues that parental role models are primary to the future family formation behavior of children. Consistent with this hypothesis, the findings concerning sexual abuse, in particular, as a predictor of both personal alcohol use and relationship satisfaction seem to underscore the importance of antecedent family characteristics in influencing later adjustment to adult roles and responsibilities.     

Friends with benefits: Social support and its relevance for farm animal welfare

Despite growing interest in promoting positive welfare, rather than just alleviating poor welfare, potential measures of good welfare, and means to provide it, have remained elusive. In humans social support improves stress-coping abilities, health, and promotes positive psychological welfare. Therefore, social support may be a key approach to promote positive physical and psychological welfare in farm animals. However, the roles of positive social behaviors and social support have been overlooked in comparison to negative social behaviors such as agonistic interactions. The benefits of social partners on an animal's stress coping abilities and welfare are yet poorly understood.The purpose of this paper is to review the protective or buffering effects of social support against stressful challenges and its potential implications for farm animal welfare. The biology of social support is first presented with its behavior, endocrine, autonomic and immune components. The major factors modulating the social support process are then synthesized. Research and implications for animal welfare in different farm species are discussed. Lastly, this review identifies research areas that especially deserve further attention in our effort to understand and implement social support in farm animal welfare.Social support could constitute one of the foundations for welfare researchers to leap from the absence of negative welfare to the provision of positive welfare and emotional experiences.     

Aggressive behavior, its adaptive function and mechanisms of development of psychosomatic disorders and diseases of adaptation

A correlation between physiologic and behavioral responses to emotional stress and agonistic conflict (triad model), as well as ideas of autonomic-humoral support of subsequent activity suggest that motor activity and situational aggressive behavior are essential final stages of stress reaction and, therefore, mechanisms of adaptation. Failure in final the stage of adaptive response causes mobilization changes to be directed against the host organism itself. This phenomenon forms the basis for psychosomatic disorders. Aggression seems to be an adaptive response not only from ethologic, but from physiologic point of view as well. It has some elements of homeostatic control (together with non-homeostatic functions). Homeostatic role of aggression may be in "elimination" of mobilization metabolic changes caused by stress reaction and physical activity by means of expressive emotional response. Aggression as a non-homeostatic factor has an ethologic function.     

The Psychosomatic Emergency

Many psychiatric problems present themselves under the guise of physical rather than mental symptoms.These occur in several categories: (1) Psychological problems which work in conjunction with definitive organic pathology, such as the fear of death. (2) Symptoms produced by altered physiology or biochemistry resultant from an acute orchronic stress state. (3) A combination of A and B above. (4) Patients with an intense disease, such as hypochondriasis. (5) Psychiatric symptoms, such as depression, anxiety or apathy which develop antecedent or subsequent to a fearfully anticipated illness or procedure.These patients have certain characteristics in common. (1) They manifest a disproportionate concern over symptoms. (2) The symptoms are inconsistent with the usual pattern of organic disease. (3) The onset is concurrent with states of conflict. (4) There is usually a personal and family history of psychic and psychosomatic disorders. (5) Other psychiatric disorders are usually present. (6) Secondary gain is usually evident.These patients can be successfully treated within the hospital setting and within the framework of psychiatric consultation and psychotherapy.

Psychological symptoms among workers employed in companies undergoing privatization in postwar Bosnia and Herzegovina

In Central and Eastern European countries, after abandoning communism, significant political, economic and social changes occurred, followed by the increase in income inequality and social disparity. The goal of this study was to examine the relationship between psychological symptoms and monthly income of employees in companies undergoing privatization. The study included 258 workers from seven companies undergoing privatization in the Tuzla Canton region. For the study purposes, the Brief Symptom Inventory (BSI) and a general questionnaire with questions about socio-demographic characteristics, income, and workplace, were used. Monthly income of the majority of workers (207 or 80.2%) was below the monthly income in Bosnia and Herzegovina. Workers with salaries below the average salary for Bosnia and Herzegovina have pronounced somatization, anxiety, paranoia, interpersonal sensitivity and hostility. The BSI scale yielded significant negative correlation between the level of monthly salary and the expression of psychological symptoms (r = -0.184, p = 0.002) and between the level of family income and the expression of psychological symptoms (r = -0.123, p = 0.024). Based on the study results, it was determined that socio-economic factors such as the level of salary and total family income and job insecurity, educational level, marital status and gender may be predictors of psychological symptoms.     

Giving social support to outside family may be a desirable buffer against depressive symptoms in community-dwelling older adults: Japan gerontological evaluation study

Background

Depression is the leading cause of impaired quality of life and burden upon societies. Social supports can buffer against depressive symptoms effectively. The aim of this study is to determine the type of social support to have a positive relationship with depressive symptoms in healthy population.

Methods

11,869 male and 12,763 female residents within the age range of 65–100 were analyzed cross-sectionally with regard to depressive symptoms (evaluated by the Japanese version of the 15-item Geriatric Depression Scale), social supports (four dimensions: giving or receiving, emotional or instrumental), and covariates utilizing data collected by the Japan Gerontological Evaluation Study. Analyzed　participants were GDS scores?≤?10 and independence in ADL, who could give and receive supports well. Multiple linear models were applied for the analysis.

Results

All supports between husband and wife were significantly associated with lower depressive degrees. In comparison with the differences between receiving and giving supports in predictive effects on depressive degrees, giving social supports to outside family, emotional or instrumental, were associated with fewer depressive symptoms.

Conclusions

There is a possibility that not only supports between husband and wife but giving social supports to outside family accounts for psychological benefits against depression, in addition to supports between husband and wife.

     

Mental Distress,Obesity and Body Fat Distribution in Middle-Aged Men

Previous epidemiological studies have suggested that psychiatric symptoms are associated with obesity and abdominal distribution of body fat in women. The aim of the present study was to examine this in middle-aged men. In 1992 a cluster selected cohort of 1040 men born in 1944 (participation rate 79.9%) was examined. Registrations of symptoms of depression and anxiety, sleep disturbances, psychosomatic disease as well as degree of life satisfaction were analyzed in relation to body mass index (BMI) and the waist/hip circumference ratio (WHR). In univariate analyses both BMI and WHR correlated with these factors. BMI and WHR were, however, closely interrelated (p=0.61), necessitating analyses of separate, independent relationships in multivariate analyses. When adjusted for WHR all the significant relationships with BMI disappeared. In contrast the WHR, adjusted for BMI, showed remaining significant associations with the use of anxiolytics (p=0.018), hypnotics (p=0.029), antidepressive drugs (p=0.008), degree of melancholy (p=0.002), and life satisfaction (p=0.002, negative), difficulties to sleep (p=0.014) and fall asleep (p=0.047), tendency to wake up from sleep (borderline, p=0.070) and dyspepsia (p < 0.001). Since smoking and alcohol are known to influence on the WHR, these factors were, in addition to BMI, entered into the analyses as confounding variables. The mentioned associations then remained statistical significant (use of hypnotics borderline, p=0.074) except difficulties to fall asleep and tendency to wake up. It was concluded that in contrast to BMI, the WHR is associated with symptoms of depression and anxiety with associated sleep disturbances, as well as psychosomatic symptoms and dissatisfaction. It was hypothesized that the mechanism involved might be increased secretion of Cortisol, directing storage fat to central adipose tissue depots.     

Do Conflict Resolution and Recovery Predict the Survival of Adolescents' Romantic Relationships?

Numerous studies have shown that being able to resolve and recover from conflicts is of key importance for relationship satisfaction and stability in adults. Less is known about the importance of these relationship dynamics in adolescent romantic relationships. Therefore, this study investigated whether conflict resolution and recovery predict breakups in middle adolescent couples. Couples who are able to resolve and recover from conflict were expected to demonstrate a lower probability of breaking up. In total, 80 adolescent couples (M age = 15.48, SD = 1.16) participated in a 4-wave prospective questionnaire and observational study, with one year between measurements. In addition to self-report measures, adolescents were observed in real-time during conflicts with their partners. Multilevel Proportional Hazard analyses revealed that, contrary to the hypothesis, conflict resolution and conflict recovery did not predict the likelihood of breakup. Survival differences were not attributable to conflict resolution or conflict recovery. More research is needed to consider the unique relationship factors of adolescent romantic relationships to determine why some relationships survive while others do not.
