Temporal constraints on binding? Evidence from quantal state transitions in perception

Do behavioural observations on the transitions between alternative perceptual interpretations of stimuli carry information about temporal characteristics of brain activity involved in binding? Promising methods for capturing critical attributes of this activity are the psychophysical methods of parameter adjustment. Of particular value are situations that include an adjustment of periodically repeating components, since the interaction of these with periodic “carrier processes” in the brain may produce informative patterns of interference. Previous evidence reveals that in different paradigms the spectral time signatures of transition tune in to a superordinate structure of quantal time values. In agreement with predictions of the taxonomic “time quantum model” (TQM), quantal time values are organized in groups called ranges which cover intervals of discretely varying sizes. These findings suggest properties characteristic of oscillatory mechanisms which are active in temporal binding. Of critical importance is the extreme precision of timing, agreement of critical periods across individuals, as well as across tasks of varying complexity, and indications of single-shot timing.     

Juegos en Dinamica de Grupo (Games in Group Dynamics)

Abstract

It is widely recognized that military service during wartime can take a toll on a soldier’s psychological health. Recent work has revealed effects on the families left behind as well, as reflected, for example, in an increase in child abuse and neglect in these families. My interest in studying the transgenerational transmission of trauma led me to offer the National Guard a pro bono group therapy for women whose husbands had been deployed overseas. A slightly unorthodox approach paved the way not only to group treatment but, ultimately, individual treatment for these women and their children. My hope is that this work can serve as a model for other therapists who share my interest in treating the intergenerational transmission of trauma by implementing group and mother-child psychotherapy.     

Reasoning About Collectively Accepted Group Beliefs

A proof-theoretical treatment of collectively accepted group beliefs is presented through a multi-agent sequent system for an axiomatization of the logic of acceptance. The system is based on a labelled sequent calculus for propositional multi-agent epistemic logic with labels that correspond to possible worlds and a notation for internalized accessibility relations between worlds. The system is contraction- and cut-free. Extensions of the basic system are considered, in particular with rules that allow the possibility of operative members or legislators. Completeness with respect to the underlying Kripke semantics follows from a general direct and uniform argument for labelled sequent calculi extended with mathematical rules for frame properties. As an example of the use of the calculus we present an analysis of the discursive dilemma.     

Relationships between Ambivalent Sexism and the Five Moral Foundations in Domestic Violence: Is it a Matter of Fairness and Authority?

Ambivalent sexism has served to justify and maintain patriarchy and traditional gender roles characterized by inequality and male domination in the intimate partner violence (IPV) literature; according to the Moral Foundation Theory (MFT) there are two specific moral foundations related to inequality and domination: fairness and authority. We connect these separate fields arguing that sexist attitudes can be related to specific patterns of endorsement of the five moral foundations. Our hypothesis is that ambivalent sexism in men convicted of violence against the partner may be rooted in at least these two moral foundations, and that at least these two moral foundations may also serve to predict intention to change the violent behavior against the partner. Controlling for political orientation, the results show that benevolent sexism correlates positively with the authority foundation; and hostile sexism correlates negatively with the fairness foundation. Both foundations contribute to explaining the two dimensions of ambivalent sexism (benevolent and hostile) and only the fairness foundation predict intention to change the violent behavior against the partner. New treatment approaches could be designed to increase moral concerns about fairness and to reduce moral concerns about authority in people who, at least, have once used violence against their partners.     

Religious Affiliation,Denominational Homogamy,and Intimate Partner Violence Among U.S. Couples

Intimate partner violence (IPV) is a major public health issue. Few studies, however, have examined the role of religion in IPV perpetration and victimization. This study analyzed the contribution of religious factors to IPV risk and prevalence among a sample of 1,440 married couples interviewed for the 1995 National Study of Couples. Results indicate that rates of IPV did not significantly differ by couple homogamy/heterogamy or type of denominational affiliation. Attendance at religious services at least weekly was associated with lower rates of IPV perpetration among men and with lower rates of IPV victimization among men and women. These findings were attenuated in the multivariate logistic regression analyses. Study findings suggest that religion does not have a strong or direct influence on the occurrence of IPV; alcohol‐related problems, however, may be a mediating factor. Despite the null findings, religious institutions can play an important role in primary and secondary IPV prevention.     

Human and peoples' rights: social representations among Cameroonian students

Social representations of human and peoples' rights were studied among Cameroonian university students (N = 666) with a questionnaire based on the UN Declaration of Human Rights and the African Charter on Human and Peoples' Rights and Duties. The respondents were asked how important and how well realized they regarded the 39 human and peoples' rights to be. A 13-factor model provided the best fit with Cameroonian students' perceptions of human and peoples' rights. Taken as a whole, our results are in line with previous quantitative studies on human rights, confirming structural similarity but also country-specific variation in the aggregation of specific rights. Moreover, our data showed that Cameroonian students value human and peoples' rights highly (M = 6.18), whereas their fulfillment is not regarded as highly (M = 5.09). Same law for all, equality and freedom, and right to work and living were highly appreciated but lowly realized rights. Higher than average in importance and realization were right to education and self-fulfillment, right to marriage and property, peoples' social and political basic rights and right to life and safety. Low in importance and realization were peoples' right to their country's natural resources and independence, right to meetings, and right to express opinion. Women appreciated the rights more than men and thought of their rights as better realized compared to men. We suggest that when women say that their rights are better fulfilled than men do, it is in comparison with the older generation, who are still very dependent on men. Nowadays, thanks to education and urbanization, young women have wider choices or opportunities for marriage and jobs. Men may feel frustrated in the context of political liberalization because the freedoms are more theoretical than fulfilled; the economic crises and cultural changes have hindered their economic domination and their prerogatives.     

Ultra-precise quantal timing: Evidence from simultaneity thresholds in long-range apparent movement

Conditions for the disappearance of long-range apparent movement were investigated. In an experiment on beta motion, critical interstimulus intervals (ISIs) of downward simultaneity thresholds for stimuli presented in continuous alternation were determined for exposure durations (EDs) varying from 3 to 160 msec. Each subject performed each test twice. Data were collected in three sessions, each for one of three angular separations (3°, 6°, and 12°) and the full set of EDs. The distribution of critical ISIs collapsed across subjects, EDs, and angular separations shows sharp maxima at regular distances within a range of 0–110 msec ISI. Significant or near-significant peaks were found at ISIs of 5, 9,22,27, 43, 55, and 107 msec. Although mean critical ISIs shifted with spatial separation, no essential shift of the main maxima occurred. Evidence of a periodic modulation with a period duration of 4.5 msec was obtained from the distributions of differences between critical ISIs of the first tests and their replications, which exhibit extremely low standard deviations (< 10 msec). These results agree well with previous analyses (Geissler, 1987, 1992) that led to a taxonomic model of quantal timing, briefly summarized in this paper. Further consequences are discussed and related to earlier developments (Geissler, 1991, 1992,1997).
