Report on work in progress: “Towards a new science of the human”

A multidisciplinary and global study of the evolutionary process of the universe in general and mankind in particular is proposed, drawing from both modern science, approached by taking into consideration its various interdependent aspects; and the study of western and eastern ancient traditions, which prove to have a common foundation that is the comprehension and the control of the evolutionary process itself.

Such a study will lead to the compilation of a “Corpus Unus” of the new science of the human, a science which does not belong to a race, a culture or an age, but is specific to the human being as such.

Such a science will imply the exploration of mankind and of the evolutionary process, and applying the results in a pragmatic way to the betterment of human beings, society, and universe.     

Effectiveness of parent counselling in eating disorders

ABSTRACT

Eating Disorders (ED) are often severe illnesses entailing a heavy burden for families. Family therapy is recommended for young patients, but only a few studies have investigated therapeutic interventions with families tailored also to adult and longstanding patients. We recruited 87 families with daughters affected by an ED, aiming to assess the effectiveness of eight sessions of parent counselling. The primary outcome was the improvement of parents' coping abilities to achieve more effective support skills. Before treatment, 54% of parents showed poor coping resources whereas 43.7% of the sample improved after parent counselling. Parents with good coping resources responded significantly better to this treatment. Although future research is warranted, these preliminary findings support the effectiveness of parent counselling in ED.     

The Isolation of Motivational, Motoric, and Schedule Effects on Operant Performance: A Modeling Approach

Dissociating motoric and motivational effects of pharmacological manipulations on operant behavior is a substantial challenge. To address this problem, we applied a response‐bout analysis to data from rats trained to lever press for sucrose on variable‐interval (VI) schedules of reinforcement. Motoric, motivational, and schedule factors (effort requirement, deprivation level, and schedule requirements, respectively) were manipulated. Bout analysis found that interresponse times (IRTs) were described by a mixture of two exponential distributions, one characterizing IRTs within response bouts, another characterizing intervals between bouts. Increasing effort requirement lengthened the shortest IRT (the refractory period between responses). Adding a ratio requirement increased the length and density of response bouts. Both manipulations also decreased the bout‐initiation rate. In contrast, food deprivation only increased the bout‐initiation rate. Changes in the distribution of IRTs over time showed that responses during extinction were also emitted in bouts, and that the decrease in response rate was primarily due to progressively longer intervals between bouts. Taken together, these results suggest that changes in the refractory period indicate motoric effects, whereas selective alterations in bout initiation rate indicate incentive‐motivational effects. These findings support the use of response‐bout analyses to identify the influence of pharmacological manipulations on processes underlying operant performance.     

The positive effect of negative emotions in protracted conflict: The case of anger

Extant research has demonstrated the destructive role that anger plays in the context of intergroup conflict. Among other findings, it has been established that anger elevates public support for aggressive and violent actions towards the outgroup. This finding has been explained by the unique cognitive appraisals, emotional goal, and response tendencies associated with anger, typified by appraised relative strength and high control, motivation to correct perceived wrongdoings, and willingness to engage in risky behavior. In the current work we examine an innovative assumption, according to which the apparent destructive implications of anger are a result of situational range restriction—namely, that anger as a group emotion has been examined almost solely at the escalation stage of conflict. Instead, we propose that the same unique characteristics of anger can bring about constructive political attitudes and support for non-violent policies in the context of systematic efforts to de-escalate a protracted conflict.To test this hypothesis we conducted two studies in which we examined the relationship between anger and the willingness to engage in positive risk-taking and support non-violent policies in the context of political negotiations between adversaries. Results indicate a significant positive relationship, supporting the hypothesis that anger is not an exclusively militant emotion, and its effects are situationally dependent.     

Young children's understanding of violations of property rights

The present work investigated young children’s normative understanding of property rights using a novel methodology. Two- and 3-year-old children participated in situations in which an actor (1) took possession of an object for himself, and (2) attempted to throw it away. What varied was who owned the object: the actor himself, the child subject, or a third party. We found that while both 2- and 3-year-old children protested frequently when their own object was involved, only 3-year-old children protested more when a third party’s object was involved than when the actor was acting on his own object. This suggests that at the latest around 3 years of age young children begin to understand the normative dimensions of property rights.     

Bypassing shame and conversion disorder

We report a case of conversion disorder (partial aphonia) that was successfully treated with speech therapy. During the one year duration of this illness, the patient regained transiently (minutes) her normal speech on a few occasions, independently of concomitant pharmacological interventions. One year after recovery she developed aphonia for the second time, which responded again to speech therapy, although the response rate was slower. Several mechanisms of conversion disorder are reviewed as specifically applied to this case. The possible role of pertinent shame mechanisms in the conversion pathology is discussed.     

Assessment of hormonal parameters and psychological well‐being in healthy subjects after a Taoist qigong program: An exploratory study

Qigong is an ancient form of health maintenance, which is part of Traditional China Medicine. Numerous beneficial mental and physical effects have been classically ascribed to this traditional psychosomatic method. The purpose of this work has been to assess the effects of Taoist qigong practice on several hormonal parameters of the Hipotalamic‐Pituitary‐Adrenal axis and specific measures of psychological well‐being in healthy subjects. Forty‐three healthy volunteers participated in the study, of whom 22 were randomly allocated to the experimental group, and 21 were assigned to the control group. Experimental participants underwent a qigong training program for one month. Blood samples for the quantification of hormonal parameters, and several instruments to assess anxiety and depression symptoms as well as subjective sleep quality, were obtained before and after the program. Statistically significant differences were found between the experimental and control groups, with the experimental group showing lower blood levels of adrenocorticotropic hormone (ACTH). This study shows that Taoist qigong is a psychosomatic method able to exert a modulatory action on ACTH levels in healthy subjects. We consider the need to continue exploring the psychobiological modulation of this qigong method and its possible repercussion for human health care.     

The Refined Extension Principle for Semantics of Dynamic Logic Programming

Over recent years, various semantics have been proposed for dealing with updates in the setting of logic programs. The availability of different semantics naturally raises the question of which are most adequate to model updates. A systematic approach to face this question is to identify general principles against which such semantics could be evaluated. In this paper we motivate and introduce a new such principle the refined extension principle. Such principle is complied with by the stable model semantics for (single) logic programs. It turns out that none of the existing semantics for logic program updates, even though generalisations of the stable model semantics, comply with this principle. For this reason, we define a refinement of the dynamic stable model semantics for Dynamic Logic Programs that complies with the principle.     

The relationship between the need for closure and support for military action against Iraq: moderating effects of national attachment

A variety of studies suggest that a high need for closure--that is, a desire for knowledge that is clear, stable, and unambiguous as opposed to confusing or uncertain--may be associated with greater hostility toward relevant outgroups. Using international attitudes as the context, the authors examine the hypothesis that the relationship between the need for closure and support for military action against Iraq may be moderated by identification with the national ingroup. Specifically, it is expected that this relationship will be moderated by nationalism (i.e., an aggressive form of identification based on a desire for national dominance) but not patriotism (i.e., a more neutral love of one's country). The data provided a clear pattern of support for this hypothesis and additional analyses indicated that a high need for closure reduced variability about the use of force among the highly nationalistic but not the highly patriotic.
