This paper proposes that mammals exhibit three primary emotion categories for mating and reproduction: (1) the sex drive, or lust, characterized by the craving for sexual gratification; (2) attraction, characterized by increased energy and focused attention on one or more potential mates, accompanied in humans by feelings of exhilaration, “intrusive thinking” about a mate, and the craving for emotional union with this mate or potential mate; and (3) attachment, characterized by the maintenance of close social contact in mammals, accompanied in (...) humans by feelings of calm, comfort, and emotional union with a mate. Each emotion category is associated with a discrete constellation of neural correlates, and each evolved to direct a specific aspect of reproduction. The sex drive is associated primarily with the estrogens and androgens; it evolved to motivate individuals to seek sexual union. The attraction system is associated primarily with the catecholamines; it evolved to facilitate mate choice, enabling individuals to focus their mating effort on preferred partners. The attachment system is associated primarily with the peptides, vasopressin, and oxytocin; it evolved to motivate individuals to engage in positive social behaviors and assume species-specific parental duties.During the evolution of the genus Homo, these emotion systems became increasingly independent of one another, a phenomenon that contributes to human mating flexibility and the wide range of contemporary human mating and reproductive strategies.

Objective Recent legislation mandating the inclusion of children in clinical trials has resulted in an increase in the number of children participating in research. We reviewed the literature regarding the reasons parents chose to accept or decline an invitation to enrol their children in clinical research. Methods We searched for qualitative studies, written in the English language that considered the experiences of parents who had been invited to enrol their children in research. SCOPUS and Web of Knowledge electronic databases and (...) reference lists of retrieved articles and review papers were searched. Retrieved articles were synthesised using the narrative synthesis method. Results 16 qualitative studies exploring the experiences of parents living in five countries whose children had a range of health conditions of varying severity were included. The health status of the child appeared to influence parents' reasons for participation. Parents whose children had life threatening conditions often considered they had no choice but to participate and many welcomed the innovation offered through research participation. Such parents also viewed the risks of research less negatively than those whose children were healthy or in the stable stage of a chronic condition. This raises questions regarding the voluntariness of informed consent by such parents. Conclusions A tailored approach is needed when discussing research participation with parents of eligible children. While parents of healthy children may be more open to discussions of altruism, those whose children have life threatening illnesses should be given adequate information about the alternatives to, and risks of, research participation.

Although the generation of reactive oxygen species is an activity normally associated with phagocytic leucocytes, mammalian spermatozoa were, in fact, the first cell type in which this activity was described. In recent years it has become apparent that spermatozoa are not the only nonphagocytic cells to exhibit a capacity for reactive oxygen species production, because this activity has been detected in a wide variety of different cells including fibroblasts, mesangial cells, oocytes, Leyding cells endothelial cells, thryroid cells, adipocytes, tumour cell (...) and platelets. Since the capacity to generate reactive oxygen species is apparently so widespread, the risk‐benefit equation for these potentially pernicious molecules becomes a matter of intese interest. In the case of human spermatozoa, the risk of manufacturing reactive oxygen metabolites is considerable because these cells are particularly vulnerable to lipid peroxidation. Indeed, there is now good evidence to indicate that oxygen radicals are involved in the initiation of peroxidative damage to the sperm plasma membrane, seen in many cases of male infertility. This risk is off‐set by recent data suggesting that superoxide anions and hydrogen peroxide also participate in the induction of key biological events such as hyperactiavated motility and the acrosome reaction. Thus, human spermatozoa appear to use reactive oxygen species for a physiological purpose and have the difficult task of ensuring the balanced generation of these potentially harmful, but biologically important, modulators of cellular function.

Indicates that post-modernist and mainstream psychologists who accept social constructionist arguments that posit a social context within which to describe human thought, emotion, and language as discourse conventions, in fact, support context as a class of events that can neither be opposed nor superseded. When scientific power-positioning is attributed to psychologists, while social contextualism is walled off from the same accusation, power over categories results. The elimination of dualities of mind and body and of thought and language, and a resulting (...) inability of the individual to assign meanings or think about emotions, isolates emotion and thought from logic and meaning. It is argued that the assumption that political context surrounds all psychological thinking suspends a host of contraries; and that the egalitarian counterclaim of post-modernists is contradicted by the very political power matrix within which it is stated. 2012 APA, all rights reserved).

This study explored over 100 Year 6 children's feelings towards, and behaviour within, literacy lessons across an academic year. This study revealed that the majority of dissatisfied children concealed their feelings from their teacher, defined within this article as 'dissatisfaction behind a veil of compliance'. Through progressive sampling, where children were observed in a range of subjects, the effort placed in this concealment is explored, together with the role of the teacher and external forces in potentially encouraging it. The article (...) concludes by discussing the possibility of applying the implications of the findings to practice, especially in terms of providing a more open environment, where teachers and pupils can express their views, openly and constructively.

This volume expands the concept and role of the schema, with three goals in mind: 1) to outline the continuing issues in the schema concept as the legacy of Kant's concept and analysis, 2) to show that Kant's challenges resulted in successful but truncated views of the schema and its functions, 3) to reconstruct Otto Selz's schema concept by proposing an alternative. The basis and scope of Selz's schema were intended to yield a more complete follow-up to Kant's challenges. These (...) had emerged out of his unresolved view of the schema as knowledge, on one hand, and thought, on the other. Sel'z concepts-'anticipatory schema,' 'coordinate relations,' and 'knowledge complex'-are more inclusive and psychologically dynamic than those of the influential but reductionist theorists: Piaget, Bartlett, and Craik. Harwood Fisher explores Sel'z ideas in past, present, and future temporal contexts. His predecessors' and his contemporaries' ideas influenced him. Present-day needs and future prospects round out a Selzian conception of the schema that would enrich a psychology of thought and knowledge. Harwood Fisher is Professor Emeritus, City College, City University of New York, USA. (shrink)
