Quantum information in an evolutionary perspective

An approach to quantum phenomena is reviewed that deals with the possibility of their realistic interpretation in the sense that they represent manifestations of hermeneutic circles between quantum “objects” and their experimental boundary conditions. Quantum cybernetics provides an evolutionary perspective in that all higher‐level organizations like molecules, cells, living systems, etc., can be discussed under one and the same systemic viewpoint: a hermeneutic circularity between a “core” (or “nucleus") and a relevant “periphery” (or “environment") which constitutes the systems’ organization and information potential.

Generally, in realistic theories, an individual quantum system is analyzable into a local “particle‐like” nonlinearity of a generally nonlocal “wave‐like” mode of some sub‐quantum structure of the vacuum ("Dirac ether"). In this view, a “particle” can be considered as being “guided” along one specific route by the (generally nonlocal) configurations of superimposed waves, which spread along all possible paths of an experimental setup. Moreover, in the approach of Quantum Cybernetics, an additional focus is given on the fact that the energy and momentum of a particle also determine the wave behavior. Thus, “waves” and “particles” are mutually and self‐consistently defined, and Quantum Cybernetics puts particular emphasis on the circular relationship—mediated by plane waves—between a quantum system and its macroscopically defined boundary conditions.     

An evolutionary perspective on hemispheric asymmetries

The evolution of hemispheric specialization of function has obvious benefits in terms of overall processing capacity, but it may also have associated costs to each hemisphere in isolation. These costs are not apparent in an intact brain since information can be readily transferred between the hemispheres via the cortical commissures. We suggest that the evolution of language in the left hemisphere may have occurred at the expense of some visuospatial functions. Because the right hemisphere was still capable of performing those functions, the relative left-hemisphere impairment for visuospatial processing would be invisible. If the cortical commissures are severed, as in callosotomy patients, the costs of specialization may become more apparent. We report data supporting the idea that the left hemisphere may have lost visuospatial abilities that it once possessed, and suggest that this process may also result in right hemisphere deficits in abilities related to linguistic processing.     

Advances in stalking risk assessment

Over the past 15 years, forensic mental health has become more concerned with the concepts of violence prevention, management, and treatment. The development of specialist tools to aid in the assessment of a range of risks reflects this concern. This article explores contemporary thinking on violence risk assessment and how this knowledge can be applied to the relatively newer field of stalking risk assessment. The role of risk state and risk status are discussed, in addition to the way that standard structured professional judgment procedures need to be adapted to reflect the variety of risks present in stalking situations. The authors go on to describe the development and format of the Stalking Risk Profile, a set of structured professional judgment guidelines for assessing risk in stalkers. Suggestions are made for future research to enhance knowledge and improve practice in the field of stalking risk assessment.     

Children,childhood, and development in evolutionary perspective

We examine children, childhood, and development from an evolutionary perspective. We begin by reviewing major assumptions of evolutionary–developmental psychology, including the integration of “soft” developmental systems theory with ideas from mainstream evolutionary psychology. We then discuss the concept of adaptive developmental plasticity and describe the core evolutionary concept of developmental programming and some of its applications to human development, as instantiated in life history theory and the theory of differential susceptibility to environmental influence. We then discuss the concept of adaptation from an evolutionary–developmental perspective, including ontogenetic and deferred adaptations, and examine the development of some adaptations of infancy and childhood from the domains of folk psychology and folk physics. We conclude that evolutionary theory can serve as a metatheory for developmental science.     

Same-gender stalking in Sweden and Australia

This study examined the phenomenon of same-gender stalking and sought to identify differences between same- and opposite-gender stalking cases. Ninety-four same-gender and 160 opposite-gender stalking cases from Sweden and Australia were compared on demographic, offense, clinical, and behavioral characteristics. The groups were largely similar, differing mainly in the nature of the prior relationship between stalker and victim and the stalker's motivation. The most notable distinction was the significantly greater prevalence of ex-intimate partner stalkers in the opposite-gender group (65%) versus the same-gender group (32%), leading to the exclusion of ex-intimates from the subsequent analysis to remove this potentially confounding variable. Amongst non-ex-intimates, same-gender stalkers were significantly more likely to be female and to stalk out of a sense of resentment and grievance. The results showed that the gender of the victim and perpetrator was less important to the course and conduct of a stalking episode than were the stalker's motivation and the nature of the prior relationship to the victim.     

Mate preferences in Argentinean transgender people: An evolutionary perspective

Transgender people provide a unique opportunity to examine the effect of biological sex versus gender identity on mating preferences. This study aimed at identifying the mate characteristics that are most and least valued by transgender people and at examining to what extent their biological sex or their gender identity determined their mate preferences. A convenience sample of 134 male‐to‐female (MTF) and 94 female‐to‐male (FTM) individuals from Argentina rated Buss's list of 18 mate attributes. Compared to FTM, MTF individuals placed significantly more emphasis on attractiveness and socioeconomic status, whereas FTM, more than MTF individuals, valued partners with a dependable character. Although biological sex differences were present in both groups, providing support to the evolutionary theory, MTF individuals valued the same characteristics as both biological male and female individuals do.     

Key questions to consider in stalking cases

Stalkers can inflict severe injury upon and have been known to kill their victims. Based on the detailed responses of 1,565 stalking victims, a set of key questions was produced with the aim of increasing the opportunities of police officers to identify potentially dangerous stalkers. Despite marked methodological differences and the inclusion of a large number of variables, regression analyses for significant correlates for physical assault per se and for severe violence largely reflected the results of earlier works. For severe violence (n=136), the most important correlate was a high level of victim fear, suggesting that victims are adept at assessing their own risk of stalker violence. The set of 11 questions performed well on preliminary tests and is presented here.     

Loneliness within a nomological net: An evolutionary perspective

Loneliness is characterized by feelings of social pain and isolation and has both heritable and unshared environmental underpinnings. An evolutionary theory of loneliness is outlined, and four studies replicate and extend prior research on the characteristics of lonely individuals. Studies 1 and 2 indicate that loneliness and depressed affect are related but separable constructs. Study 3 confirms that lonely, relative to nonlonely, young adults are higher in anxiety, anger, negative mood, and fear of negative evaluation, and lower in optimism, social skills, social support, positive mood, surgency, emotional stability, conscientiousness, agreeableness, shyness, and sociability. The set of six personality factors associated with loneliness (surgency, emotional stability, agreeableness, conscientiousness, shyness, and sociability) do not explain the associations between loneliness and negative mood, anxiety, anger, optimism (pessimism), self-esteem, and social support, as each association remained statistically significant even after statistically controlling for these personality factors. Study 4 used hypnosis to experimentally manipulate loneliness to determine whether there were associated changes in the participants’ personality and socioemotional characteristics. Results confirmed that loneliness can influence the participants’ personality ratings and socioemotional states.     

The basic cognition of jealousy: an evolutionary perspective

Penke and Asendorpf (European Journal Of Personality, vol 21, this issue) argue compellingly that research on jealousy would benefit from more direct investigation of cognitive processes, and report on research providing mixed evidence for sex differences in jealousy. We identify three limitations to the empirical approach utilised by Penke and Asendorpf, and highlight novel conceptual and methodological approaches for directly examining the basic cognitive mechanisms associated with jealousy and intrasexual rivalry. Investigating the basic cognition of intrasexual rivalry will help expand the scope of jealousy‐related research. Copyright © 2007 John Wiley & Sons, Ltd.     

An evolutionary cybernetics perspective on language and coordination

Starting from the observation that many open issues in linguistics hinge on problems of semantics, we discuss three core semantic notions: categories, agency, and qualification or semiosis. We argue that the origin of these coincide with the emergence of self-regulatory systems, systems that control their own persistence as localizable dynamical systems. When such systems interact a metasystem transition can occur in which the regulatory capacity per system is increased through the mechanisms of extension and specialization. Newly arising mutual dependencies force the formerly independent systems to coordinate their behaviour which leads them to effectively become a single system – a novel agency at a higher level of organization – thus qualifying the emergence of a novel language or code. We go on to argue that natural languages are instances of such naturally occurring conventionalization processes, corroborating the view that language should primarily be characterized as coordination.     

Cross-cultural patterns in the training of children: an evolutionary perspective

Analyzed cross-cultural child inculcation data from Barry, Josephson, Lauer, & Marshall (1976) by testing a hypothesis derived from natural selection theory: The ways in which boys are trained (vs. those for girls) should correlate with male and female reproductive strategies prevalent in each society. Boys are trained to be more aggressive, show more fortitude, and be more self-reliant than girls; girls are trained to be more industrious, responsible, obedient, and sexually restrained than boys. The more polygynous the society (the higher the potential reproductive rewards for males), the more sons in nonstratified societies were taught to strive. Stratified societies, which restrict men's reproductive striving, showed very different patterns. The more actual control women in any society had over resources, the less daughters were taught to be obedient.     

College students' Facebook stalking of ex-partners

There are abundant anecdotes and warnings of inappropriate behaviors on social networking sites, particularly about Facebook. The purpose of the present study was to examine whether individuals obsessively monitor or harass their ex-partners on Facebook (related to general "Facebook stalking") and, if so, whether those individuals would also engage in cyber obsessional pursuit (COP) and obsessive relational pursuit (ORI), which are categories of cyberstalking and stalking. A total of 411 valid participants answered questions about the ways they communicated with their ex-romantic partners using Facebook, resulting in three factors: Covert Provocation, Public Harassment, and Venting. Each category of Facebook harassment was related to perpetration of COP and ORI. Additionally, participants who engaged in COP were almost six times more likely to also perpetrate ORI. If participants admitted to engaging in some types of stalking behaviors, they did so online, offline, and on Facebook. Implications for social networking site usage and stalking laws are discussed. There is a kernel of truth to the popular term "Facebook stalking."     

面孔吸引力和配偶价值:进化心理学视角

面孔吸引力是对个体容貌的审美评价。根据进化心理学的观点,面孔吸引力是配偶价值的线索。这一假设是进化心理学视角下的面孔吸引力研究的前提所在。本文就涉及这一核心假设的研究进行梳理,重点关注影响面孔吸引力的形态特征与配偶价值的关系。这些形态特征包括面孔的性别二态性特征,面孔的波动性不对称特征以及面孔的肥胖特征。     

An evolutionary perspective on effective vs. ineffective pick-up lines

This experiment examined women's impressions of men using various "pick-up" lines. Seventy women imagined being approached by a man using a flippant and flirtatious "pick-up" line, a direct complimentary line, or an innocuous line that masks his interest. His attractiveness varied too. They then considered him for long-term or short-term relationships. Matching a "good dad" hypothesis, they favored him for a long-term relationship if he used a direct or innocuous line instead of the flippant line, because the latter conveyed lower trustworthiness and intelligence. Matching a "good genes" hypothesis, they favored him for a short-term relationship if he was attractive instead of unattractive, regardless of his pick-up line, presumably because attractiveness signals heritable fitness. Limitations and theoretical implications are discussed.     

An evolutionary psychology perspective on sex differences in exercise behaviors and motivations

Researchers have found that men and women pursue sex-appropriate strategies to attract mates. On the basis of intrasexual competition, men should be more likely to enact behaviors to look larger, whereas women should be more likely to enact behaviors to look smaller. The types of exercises that each performs should reflect this expectation. The present study replicates and extends work by L. Mealey (1997) on sex differences in exercise behavior. In the present study, male participants focused their energy on gaining muscle mass and enhancing their upper body definition, whereas female participants focused their energy on losing weight with emphasis on their lower body. Both sexes reported efforts to improve their abdominal region. It appears that men and women adopt sex-appropriate exercise behavior as a method of self-enhancement for intrasexual competition.     

Attractiveness of blonde women in evolutionary perspective: studies with two Polish samples

An experimental study was undertaken to assess the phenomenon of male preference for blondes. In the first study, 360 Polish men ages 18 to 46 years were asked to assess the attractiveness of the presented stimuli using a 9-point scale. Stimuli were 9 different pictures of the same women whose ages (about 20, 30, and 40 years old) and hair colors (blonde, brown, and brunette) were manipulated. Pictures of blonde-haired women were generally rated as younger than the others. The attractiveness ratings of female faces changed with age and hair color. Still, only the 30-yr.-old woman with blonde hair was rated as significantly more attractive than those with brown or brunette hair. In a second study (the analysis of 500 Internet advertisements) mature women dyed their hair blonde more frequently. These results are analyzed with regard to the evolutionarily formed male preference for younger females.     

Behavioral genetic variation, adaptation and maladaptation: an evolutionary perspective

Evolutionary psychology seeks to understand the adaptive, evolved nature of humans by considering the forces of natural selection that gave rise to it. Individual humans also exhibit maladaptation, however, and some of the variation in maladaptive conditions is heritable. An evolutionary perspective can shed light on these phenomena too. Recent work suggests that developmental imprecision importantly affects the fitness of organisms and some of the genetic influences have been identified. Both theory and evidence that developmental imprecision underlies human cognitive maladaptation has begun to accumulate, although the manner in which the developing brain is affected remains largely unknown.     

Rethinking the paradigm of enterprise: A global and evolutionary perspective

The most elementary law of nature, the principle that best explains how the world works, is that actions have consequences. The consequences of enterprise (or business) will be as profitable or detrimental as the actions behind them. The rapidly approaching new millennium forces society to assess where we are (the consequences) and how we got here (the actions). The standard of living in the western world is a direct consequence of past and present enterprise, but the actions taken to get to this plateau and their associated costs may far over‐shadow the gains. A major issue facing those who study the development and evolution of enterprise is whether past merits and mistakes can be used to develop a new paradigm that is more reflective of what is currently experienced and most likely to occur in the future.

This paper discusses some of the shortcomings in current economic thinking, how current developments in economic thinking need to become the norm and the future of socio‐ecologically behavior and patterns of growth for enterprise.     

Need for more evolutionary and developmental perspective on basic emotional mechanisms

Lindquist et al.'s meta-analysis focuses on adult humans; the authors' emotion model might be strengthened by considering research on infants and animals, highlighting the importance of the limbic system. Reliance on the James-Lange theory is questionable; emotions typically occur instantaneously, with dubious dependence on bodily feedback for affect. Stronger evidence for localization might be obtained using more precise emotion terms and alterative localization methods.
