Social is Emotional

This is a biological approach to the philosophy of mind that feeds an investigation of the phenomena of “social” and “emotional”, both of which are widespread in nature. I scrutinize the non-dualistic Darwinian concept of the continuity of mind. For practical reasons, I address mind at different levels of organization: The systemic mind are the properties of which a common, coherent evolution works upon. Separated from this is “language-mind”: the crystallization of thought in words, which is a strictly human phenomenon. As the phenomenology of the body is a theory of philosophy that lie beyond language it can—to a certain extent—be extrapolated across a species boundary. In the process the phenomenology of the body comes to resemble biosemiotics and with this tool, I investigate a field study of social play behavior in canids. This leads to a possibility to study the non-human experience of emotion as “locally meaningful phenomena”.     

Elucidating inequality in Nubia: An examination of entheseal changes at Kerma (Sudan)

Located 10 km south of the Third Cataract of the Nile River, the ancient city of Kerma was once capital to the second largest state in Africa. The Eastern Cemetery at Kerma (～4 km east of city center) encompasses 80+ hectares and was used over a period of 1,500 years (3,200–1,500 BC). Excavated in the early 20th century by George Reisner, the cemetery contained an estimated 20,000–40,000 individuals. Reisner classified these burials into multiple categories, including chiefs and human sacrifices, based on burial position and grave goods. This study investigates the skeletal embodiment of social inequality by examining variation in entheseal severity between the Kerma burial classifications. Seventeen entheses were examined using the Hawkey and Merbs (1995) scoring method (n = 205 individuals); age, sex, and body size variables were considered by employing Mann–Whitney U tests and partial Spearman's correlations. This analysis suggests that significant differences in entheseal changes existed between select burial types. Specifically, “corridor sacrifices” had significantly higher rates of entheseal changes while “chiefs” and “subsidiary burials” had similar entheseal changes; furthermore, within these burial categories, males had higher entheseal scores despite body size controls. The elevated entheseal changes in the sacrificial burials may be due to an intensive agro‐pastoral lifestyle or other demanding forms of manual labor. In conclusion, the disparity of entheseal markers between burial subgroups at Kerma might reflect a degree of social inequality within this state level society. This bioarchaeological research informs our understanding of socially‐defined categories of persons as well as everyday life in Ancient Kerma.

Indirect reciprocity and the evolution of “moral signals”

Signals regarding the behavior of others are an essential element of human moral systems and there are important evolutionary connections between language and large-scale cooperation. In particular, social communication may be required for the reputation tracking needed to stabilize indirect reciprocity. Additionally, scholars have suggested that the benefits of indirect reciprocity may have been important for the evolution of language and that social signals may have coevolved with large-scale cooperation. This paper investigates the possibility of such a coevolution. Using the tools of evolutionary game theory, we present a model that incorporates primitive “moral signaling” into a simple setting of indirect reciprocity. This model reveals some potential difficulties for the evolution of “moral signals.” We find that it is possible for “moral signals” to evolve alongside indirect reciprocity, but without some external pressure aiding the evolution of a signaling system, such a coevolution is unlikely.     

Second Language Acquisition: A Framework for Studying the Importance of Input and Interaction in Exceptional Song Acquisition

Recent studies demonstrate that specific types of live input and social interaction facilitate “exceptional” song acquisition. The term “exceptional” denotes time-independent song acquisition and learning of nonspecies-specific song (or parts of song) and second dialects by birds generally thought to have restrictions on their learning capabilities. Recent research in human second language acquisition (SLA) also emphasizes the roles of input and interaction. The purpose of this paper is to focus on these parallels and suggest that SLA studies can provide further insights into exceptional song acquisition, particularly with respect to new directions for ornithological research.     

Corticosterone may interact with peripubertal development to shape adult resistance to social defeat

Studies of social stress in adult mice have revealed two distinct defeat-responsive behavioral phenotypes; “susceptible” and “resistant,” characterized by social avoidance and social interaction, respectively. Typically, these phenotypes are observed at least 1 day after the last defeat in adults, but may extend up to 30 days later. The current study examined the impact of peripubertal social defeat on immediate (1 day) and adult (30 day) social stress phenotypes and neuroendocrine function in male C57BL/6 mice. Initially, peripubertal (P32) mice were resistant to social defeat. When the same mice were tested for social interaction again as adults (P62), two phenotypes emerged; a group of mice were characterized as susceptible evidenced by significantly lower social interaction, whereas the remaining mice exhibited normal social interaction, characteristic of resistance. A repeated analysis of corticosterone revealed that the adult (P62) resistant mice had elevated corticosterone following the social interaction test as juveniles. This was when all mice, regardless of adult phenotype, displayed equivalent levels of social interaction. Peripubertal corticosterone was positively correlated with adult social interaction levels in defeated mice, suggesting early life stress responsiveness impacts adult social behavior. In addition, adult corticotropin-releasing factor (CRF) mRNA in the paraventricular nucleus of the hypothalamus (PVN) was elevated in all defeated mice, but there were no differences in CRF mRNA expression between the phenotypes. Thus, there is a delayed appearance of social stress-responsive phenotypes suggesting that early life stress exposure, combined with the resultant physiological responses, may interact with pubertal development to influence adult social behavior.     

Ethology and psychotherapy

During the last 25 years, ethology has developed systematic and quantitative methods for studying psychiatric patients' behavior, especially nonverbal behavior. Both research results as well as theoretical considerations may be of interest and value for psychiatric interviews and psychotherapy. Direct observations of endogenously depressed patients on the ward show significant behavior changes from admission to discharge. The depressive phase is characterized by withdrawal, nonspecific gaze, looking down, little self-activity, little motor activity, and a substantial reduction of social interaction. The recovery phase is characterized by verbal and nonverbal communication, that is , nod, smile, laughter, gesticulation, help, and others. Such behaviors are primarily useful for the assessment of a patient's mental state in the ward environment. In addition, they may also contribute to the psychiatric interview and future psychotherapeutic situations. These elements are related to four basic motivation categories: relaxation, assertion, contact, and flight. The theoretical considerations include evolutionary theory, ethological theory, and regulation-deregulation theory.     

Neural bases of syntax–semantics interface processing

The binding problem—question of how information between the modules of the linguistic system is integrated during language processing—is as yet unresolved. The remarkable speed of language processing and comprehension (Pulvermüller et al. 2009) suggests that at least coarse semantic information (e.g. noun animacy) and syntactically-relevant information (e.g. verbal template) are integrated rapidly to allow for coarse comprehension. This EEG study investigated syntax–semantics interface processing during word-by-word sentence reading. As alpha-band neural activity serves as an inhibition mechanism for local networks, we used topographical distribution of alpha power to help identify the timecourse of the binding process. We manipulated the syntactic parameter of verbal event structure, and semantic parameter of noun animacy in reduced relative clauses (RRCs, e.g. “The witness/mansion seized/protected by the agent was in danger”), to investigate the neural bases of interaction between syntactic and semantic networks during sentence processing. The word-by-word stimulus presentation method in the present experiment required manipulation of both syntactic structure and semantic features in the working memory. The results demonstrated a gradient distribution of early components (biphasic posterior P1–N2 and anterior N1–P2) over function words “by” and “the”, and the verb, corresponding to facilitation or conflict resulting from the syntactic (telicity) and semantic (animacy) cues in the preceding portion of the sentence. This was followed by assimilation of power distribution in the α band at the second noun. The flattened distribution of α power during the mental manipulation with high demand on working memory—thematic role re-assignment—demonstrates a state of α equilibrium with strong functional coupling between posterior and anterior regions. These results demonstrate that the processing of semantic and syntactic features during sentence comprehension proceeds in highly integrated fashion using gating of attentional resources to facilitate rapid comprehension, with attentional suppression of global alpha power to facilitate interaction of local networks.

Androgen-primed castrate males are sufficient for methamphetamine-facilitated increases in proceptive behavior in female rats

Methamphetamine (MA) is a psychomotor stimulant associated with increases in sex drive in both men and women. Women, however, are far more likely to face social disadvantages as a consequence of MA use, and their increased sexual motivation poses additional health concerns such as unplanned pregnancies. To better understand the mechanisms underlying MA-facilitated sexual motivation in females, we previously established a rodent model where a “binge”-type administration paradigm of MA to sexually receptive female rats significantly increases proceptive behavior in the presence of a sexually active, gonadally-intact male. Our previous work with this model has led us to consider whether the increases in proceptive behavior are truly indicative of increased sexual motivation, or instead a consequence of heightened motor responsivity. Here, we test whether MA-induced increases in proceptive behaviors are specific to a sexually relevant stimulus. Females' sexual, social, exploratory behaviors, and interaction times were scored during the exposure to stimulus males, including castrates, and dihydrotestosterone (DHT)-treated castrates. MA-treated females demonstrated significant increases in proceptive behaviors toward DHT-treated castrate males but not toward castrate males. While the non-MA-treated females did display proceptive behavior, there was no significant difference between behaviors elicited by DHT-CX males compared to CX males. Our results support the hypothesis that MA facilitates proceptive behavior only in response to specific, androgen mediated sexually-relevant cues.     

Bilingualism,Language Disorders and Intercultural Families in Contemporary Italy

This study aims to show how language disorders in children affect language transmission and the mixedness experience in intercultural families. To this end, it adopts a qualitative method of study based on the administration of ad hoc interviews to intercultural couples who consulted our Child Neuropsychiatry Service because of language disorders in their children. One of the main consequences, when the child of an intercultural couple presents a language disorder and a diagnostic process has to be initiated, may be interruption of the transmission of the second language, especially if it is the mother’s language. The decision to do this, which may be taken on the advice of teachers and health professionals, but also because the parents themselves often attribute their child’s language disorder to his bilingual condition, affects not only the relationship between the mother and her child, but also processes in the construction of parenthood and in the structuring of the child’s personality and the plurality of his affiliations. A clear understanding of how the dialectic between the categories of “alien” and “familiar” is managed in these contemporary families, which have to reckon with the condition of otherness, is crucial for psychiatrists and psychotherapists working in settings in which cultural difference is an issue to consider.     

A knowledge-based halogen bonding scoring function for predicting protein-ligand interactions

Halogen bonding, a non-covalent interaction between the halogen σ-hole and Lewis bases, could not be properly characterized by majority of current scoring functions. In this study, a knowledge-based halogen bonding scoring function, termed XBPMF, was developed by an iterative method for predicting protein-ligand interactions. Three sets of pairwise potentials were derived from two training sets of protein-ligand complexes from the Protein Data Bank. It was found that two-dimensional pairwise potentials could characterize appropriately the distance and angle profiles of halogen bonding, which is superior to one-dimensional pairwise potentials. With comparison to six widely used scoring functions, XBPMF was evaluated to have moderate power for predicting protein-ligand interactions in terms of “docking power”, “ranking power” and “scoring power”. Especially, it has a rather satisfactory performance for the systems with typical halogen bonds. To the best of our knowledge, XBPMF is the first halogen bonding scoring function that is not dependent on any dummy atom, and is practical for high-throughput virtual screening. Therefore, this scoring function should be useful for the study and application of halogen bonding interactions like molecular docking and lead optimization.

Sexual behavior of male pigs

Two major characteristics of males that affect the likelihood of achieving copulation are the sexual motivation and mating competency of the male. The behavior of domestic animals, including their sexual behavior, is dependent upon a complex interaction between the organism's internal and external environment. In male pigs, as in other mammalian species, it is clear that testicular steroids are required to maintain sexual behavior and testosterone plays a critical role. Consistent with studies in other species, it is apparent in male pigs that there is a threshold circulating concentration of androgens and/or estrogens required to maintain sexual behavior and that the level of sexual motivation is unrelated to levels of sex steroids providing these are adequate for normal sexual behavior. Key aspects of the external environment that affect the sexual behavior of the male pig include genetic, seasonal, social, sexual and psychological factors.     

Defaming Rover: Error-Based Latent Rhetoric in the Medical Literature on Dog Bites

This article examines the accuracy and rhetoric of reports by human health care professionals concerning dog bite injuries published in the peer-reviewed medical literature, with respect to nonclinical issues, such as dog behavior. A qualitative content analysis examined 156 publications between 1966 and 2015 identified by terms such as “dog bite” or “dangerous dogs.” The analysis revealed misinformation about human–canine interactions, the significance of breed and breed characteristics, and the frequency of dog bite–related injuries. Misinformation included clear-cut factual errors, misinterpretations, omissions, emotionally loaded language, and exaggerations based on misunderstood or inaccurate statistics or reliance on the interpretation by third parties of other authors’ meaning. These errors clustered within one or more rhetorical devices including generalization, catastrophization, demonization, and negative differentiation. By constructing the issue as a social problem, these distortions and errors, and the rhetorical devices supporting them, mischaracterize dogs and overstate the actual risk of dog bites.     

“What Do Animals Mean to You?”: Naming and Relating to Nonhuman Animals

ABSTRACT

This article presents an analysis of data from over 200 accounts of, and responses to questions about, how animals feature in people's lives. The accounts were generated by a Mass Observation Project (MOP) directive on “Animals and Humans.” The MOP, based at a UK university, sends out two or three directives a year, asking correspondents to write in response to a series of questions and prompts. The “Animals and humans” directive began with the question, “What do animals mean to you?” followed by a range of prompts about respondents' experiences of animals. The paper is specifically concerned with issues of how language both reflects and contributes to typologies of living creatures. It presents a qualitative analysis of some of the themes that emerged from responses to the directive, as well as a more quantitative analysis of the words chosen by respondents to denote different kinds of animals. Using these different methodological approaches, it focuses on how moral ambiguity is expressed and the ways in which categories and meanings shift depending on linguistic context. These methods complement each other, with the computer-assisted linguistic analysis providing a different and more quantitative method of revealing aspects of people's values, attitudes, and assumptions as they report on the role of animals in their lives. Overall, the paper shows how a corpus linguistic analysis can demonstrate the permeability of categories and boundaries, and the moral ambiguity toward animals that is revealed in the way language is used.     

Capital punishment in tribal Montenegro: Implications for law,biology, and theory of social control

Clan execution among feuding tribal societies is proposed as a significant precursor to modern law. This form of ostracism is examined with respect to its social control functions and the indigenous assumptions about behavior, genes and demography that guide the behavior. It is suggested that there are very close parallels between modern legal systems and nonliterate ones based on “self-help”, when capital punishment is used by normal decision groups in the name of “national security”.
