Paper presented at the ISTP Conference, Toronto 2007. Mate choice, courting, parental investment, attractiveness, and love are a few examples of human interactions in which evolutionary psychology has a keen interest. Theories like this shed light on human partner preferences and there is quite strong empirical support for that as well. Roughly the general version says that For any member of the sexes, if the individual is interested in long-term mating, it will select a mate that is showing to be 1. able to invest in the relationship and in their offspring 2. willing to invest in the relationship and in their offspring 3. able to physically protect self, partner and offspring 4. having good parenting skills 5. compatible with the self (has similar values, age, personality etc.) These studies show how the preferences in partner selection resemble each other. Over many countries and cultures, within and between the sexes, within and between age groups, social economic classes etc. people all are, to certain extend alike in what they like and dislike. The interpretation of what is alike, however, is a matter of debate. That is, “resemblance” always is resemblance in the eye of the persons or organisms that compare. So a preference for a certain body shape, for symmetry, for sharp male facial contours and soft contours in the female face, for a particular waist-hip ratio etc. is in the eye of the beholder. That is, in the eye of the organism involved, or at least in the eye of the sex of the organism involved, or at least in the eye of the members of a certain age, culture, historical period of the sex of the organism involved, or at least…etc. From another angle there are studies of how personal knowledge of the human body partially accounts for the experience of romantic love in humans. Helen Fisher’s work is an example. Focusing on the experiences of human beings concerning romantic love, she reports remarkable regularities in and resemblances of feelings between human beings from different countries, cultures, ages, the sexes and even, apparently, between non-human animals – primates, and some other mammals in particular. What is remarkable here is that they mostly report of either internal feelings or the bilateral meaningful behavior and expected or hoped for behavior of the one in love and the one loved.From yet one other angle, Antonio Damasio’s theory on emotions and feelings also seems to enhance evolutionary psychology’s claims. Damasio suggests that vision, hearing, touch, taste and smell result from nerve activation patterns that reflect states of the external world. Emotions, on the other hand, are nerve activation patterns that correspond to the state of the internal world. The experience of sexual attraction is activated but also recorded in nerve cell activation patterns obtained by the brain from neural and hormonal feedback, and is experienced as a body state.Briefly, we argue, the way we interpret or represent our feelings, depends on how feelings are stylized, articulated, and expressed in communities. From (socially) skilled members of the group we learn how to appropriately deal with affects

On the claims of evolutionary psychology to explain romantic love

Group Changes in Cortisol and Heart Rate Variability of Children with Down Syndrome and Children with Autism Spectrum Disorder during Dog-Assisted Therapy

Dog-assisted therapy is hypothesized to lower stress in children with autism spectrum disorder (ASD) and children with Down syndrome (DS), which may be visible on a physiological level. In this study, we measured heart rate variability (HRV) and salivary cortisol of 20 children with DS or ASD at the beginning and end of six weekly sessions of dog-assisted therapy. We found a decrease of cortisol levels during single sessions, but no overall effect after six sessions (six weeks). The effect of dog-assisted therapy on the increase of HRV could not be confirmed. This study is one of the first to use physiological measurements to test the effects of DAT.</p

Isotachophoresis in capillary tubes

A capillary-tube isotachophoresis app. consists of a capillary tube connected to 2 electrode compartments and to 2 reservoirs, 1 contg. water and the the other an electrolyte. The app. provided sepns. of some weak acids with a reproducibility of 0.5 or better. The app. is described with diagrams. [on SciFinder (R)

Isotachophoresis. Electrophoretic analysis in capillaries

The aim of this paper is to give more details about the equipment used for isotachophoretic analysis. More accurate values, quantitatively as well as qualitatively, can be obtained by thermostating the system where the thermal detector is mounted. Mobilities of the different ion species are also strongly influenced by shifts in temperature. Therefore an electric diagram is given for an aluminum thermostat in which the capillary is mounted. A secondary effect, but also an important one, is that shorter times for analysis can be obtained because higher currents can be used by the increased heat transfer. Some electric diagrams are given for differentiating electronically, which makes balancing of thermocouples1,2unnecessary. Detailed designs are given for injection blocs and electrode compartments
