Becoming uniquely human? Comparing chimpanzee to human infancy

Does comparing behavioral development between chimpanzees and humans during infancy hold the key to understanding what is uniquely human? Recent work shows that while many behaviors emerge at similar ages in chimpanzees, human infants develop behavioral traits underpinning our prosocial and ultra-cooperative nature at a much accelerated rate.     

Are there human rights?

Conclusion In conclusion, I have tried to show that if there are any rights at all, legal, moral and political, there are at least the sorts of human rights cited in the Universal Declaration, rights which extend beyond the slender base provided by Hart's right to be free and which include the right to an adequate human life for everyone, rights shared by all, rights that, as rights, imply correlative duties. Even though the duties thus implied are admittedly imperfect, as rights, they confer upon right-holders, the authority to obligate others.I have argued for the most part against regarding any rights, even some human, rights (interchangable here with manifesto rights, welfare rights, rights of recipience, social and economic rights, programme rights, Fawcett calls them, positive in rem rights) as claims to rights or proposals for adoption as rights. I have argued that to have a right of any kind, including especially a human right, one shared by and held equally by all human beings,while not unconditional or unalterable, is fundamentally important, - to return once again to Feinberg's definition at the opening of this paper. A human right is fundamentally important, however, only if it, too, implies an obligation on the part of other people, one in which other people are obligated to use their power and resources to make things happen. To havea right is to be in a position to impose corresponding obligations on others. As Kant pointed out, a right of any kind gives a right holder a title to compel.

Emotional expressions facilitate human–human trust when using automation in high-risk situations

This study investigated the utility of emotional expression for human decision aids, when human aids conflict with an automated decision support system (DSS). The increasing presence of automation in society has resulted in critical, and often life threatening, situations when information from human and automated sources disagree. It has been known that reliance on human aids decrease during high-risk situations, while reliance on automated aids increase. However, it is also possible that human decision aids gain credibility from users when they embody the charismatic and emotionally expressive gesticulations seen in successful organizational leaders. The present study tested how a human agent's expressiveness when providing information would influence participants' behavioral reliance. Using the program Convoy Leader, participants (n=56) engaged in three decision-making scenarios where risk was manipulated as a within-subject factor and emotional expression as a between-subject factor. Emotional susceptibility, perceived risk, and trust for human as well as automated aids were measured. Overall trust was higher for the automated tool than human decision aid, and that pattern was amplified in conditions without an emotionally expressive human aid. Reliance was greater for emotionally expressive human aids, than stoic human aids, particularly during high risk conditions. The findings suggest that emotional expression of a human aid significantly impacts both reliance and trust of a decision aid, especially at higher risk levels. Emotionally expressive human agents should be utilized in decision conflicts where the automated system has certainly failed.     

Are human beings free?

This article examines the question of freedom of choice (free-will) in human beings. The process of decision making is analysed and the author presents the conclusion that since this process is determined by the perceptions and interpretations of the person, it cannot be termed free. Applications are drawn to the therapeutic process, specifically in regard to anger and guilt.     

What are human express saccades?

When a fixation point is removed 200 msec prior to target onset (the gap condition), human subjects are said to produce eye movements that have a short latency (80–120 msec), that form the early peak of a bimodal latency distribution, and that have been labeled “human express saccades” (see, e.g., Fischer, 1987; Fischer & Breitmeyer, 1987; Fischer & Ramsperger, 1984, 1986). In three experiments, we sought to obtain this express saccade diagnostic pattern in the gap condition, We orthogonally combined target location predictability with the presence versus absence of catch trials (Experiment 1). When target location was fixed and catch trials were not used, we found mostly anticipations. In the remaining conditions, where responses were under stimulus control, bimodality was not frequently observed, and, whether it was or not, latencies were not in the express saccade range. Using random target locations, we then varied stimulus luminance and the mode of stimulus presentation (LEDs vs. oscilloscope) in the gap and overlap (fixation is not removed) conditions (Experiment2). Bimodality was rarely observed, the gap effect (overlap minus gap reaction time) was additive with luminance, and only the brightest targets elicited saccades in the express range. When fixed locations and no catch trials were combined with latency feedback (Experiment 3), we observed many responses in the express saccade range and some evidence for bimodality, but the sudden introduction of catch trials revealed that many early responses were not under stimulus control. Humanscan make stimulus-controlled saccades that are initiated very rapidly (80–120 msec), but unless catch trials or choice reaction time is used, it is not possible to distinguish such saccades from anticipatory responses that are prepared in advance and timed to occur shortly after target onset. Because the express saccade diagnostic pattern is not a characteristic feature of human saccadic performance, we urge investigators to focus their attention on the robustgap effect     

Are women adult human females?

Chimpanzee minds: suspiciously human?

Chimpanzees undoubtedly form concepts related to the statistical regularities in behavior. But do they also construe such abstractions in terms of mental states - that is, do they possess a 'theory of mind'? Although both anecdotal and experimental data have been marshaled to support this idea, we show that no explanatory power or economy of expression is gained by such an assumption. We suggest that additional experiments will be unhelpful as long as they continue to rely upon determining whether subjects interpret behavioral invariances in terms of mental states. We propose a paradigm shift to overcome this limitation.     

Does human capital matter? A meta-analysis of the relationship between human capital and firm performance

Theory at both the micro and macro level predicts that investments in superior human capital generate better firm-level performance. However, human capital takes time and money to develop or acquire, which potentially offsets its positive benefits. Indeed, extant tests appear equivocal regarding its impact. To clarify what is known, we meta-analyzed effects drawn from 66 studies of the human capital-firm performance relationship and investigated 3 moderators suggested by resource-based theory. We found that human capital relates strongly to performance, especially when the human capital in question is not readily tradable in labor markets and when researchers use operational performance measures that are not subject to profit appropriation. Our results suggest that managers should invest in programs that increase and retain firm-specific human capital.     

Dying: A universal human experience?

This paper explores the question, “Is there a universal psychological experience suffered by all dying persons?” a question to which the popular theory of Kübler-Ross presupposes an affirmative answer. Our answer takes three steps: first, a comparison between the Kübler-Ross model of dying and that of the late medievalBook of the Craft of Dying centered upon the five Kübler-Ross “stages”; second, a philosophical critique of the terms of this comparison; and third, a revised look at the alleged similarities between the two models, providing a deeper look at the moral and spiritual assumptions behind each.     

Should we change the human genome?

Should we change the human genome? The most general arguments against changing the human genome are here in focus. Distinctions are made between positive and negative gene therapy, between germ-line and somatic therapy, and between therapy where the intention is to benefit a particular individual (a future child) and where the intention is to benefit the human gene-pool. Some standard arguments against gene-therapy are dismissed. Negative somatic therapy is not controversial. Even negative, germ-line therapy is endorsed, if the intention is to cure a certain individual (a future child). In rare cases, positive therapy on somatic cells may be warranted. Germ-line therapy may become a valuable method of preventing harm, through ‘genetic vaccination’. If safe methods evolve, it is harmless (though vain), to try to achieve more ambitious goals. Prospective parents should not be prevented from exercising this harmless kind of parental authority. The paper concludes: Thereis a moral limit to how much we ought to manipulate the human genome, however. We ought not to jeopardize the continued existence of mankind. We ought not to develop methods of germ-line therapy intended in a radical manner to improve human nature, and we ought to leave to prospective parents to decide in individual cases what kind of intervention shall take place.     

Are there universal human being skills?

The issue of what constitutes a skilled human being is fundamental to counselling and psychotherapy. Furthermore, multicultural counselling and therapy is based on the two primary assumptions of common humanity and cultural diversity. However, nowhere have I seen in the psychotherapy theory and the multicultural literature the issue addressed of whether there are universal human being skills that underlie and transcend cultural diversity. By 'universal human being skills' I mean skills that characterize the good or effective person regardless of the culture or country in which they live. Arguably the widespread possession of such human skills throughout the world is fundamental to creating happiness and avoiding suffering on a daily basis. Furthermore, the survival of the species depends on the existence of sufficient good or skilled human beings to protect the interests of future generations.     

What's so bad about human cloning?

There appears to be a consensus in the general community that reproductive cloning is an immoral technology that should be banned. It may, however, be argued, at least from the perspective of the Jewish tradition, that reproductive cloning has many positive benefits. It is thus essential that one carefully weigh the costs and the benefits before deciding on a definitive course of action.     

Carrying human infants – An evolutionary heritage

We propose that infant carrying is a biological norm for human caregiving, given that human infants have evolved a capacity to cling onto an upright caregiver whose body co-evolved to enable offspring carrying. The origins of this mutual adaptation may date back 4 million years, with the emergence of bipedalism, which precluded the infant horizontal and gravity-supported position on the back of a quadrupedal caregiver. We describe infant cooperative reflexes and behaviors, including the carrying-induced calming response and discuss hypotheses for the invention of infant carrier tools.Carrying involves several physiological and behavioral parent-infant co-adaptations that imply it is an evolutionarily conserved strategy. Epigenetic transmission of reproductive behavior through generations affects the development of the offspring, as well as the mental health of the parent. Carrying might have contributed to the evolution of Hominidae, potentially aiding dexterity, handedness, language acquisition, and social interactions.We review the evolutionary milestones and time points where the infant-caregiver interactions might have changed, exploring infant carrying as it intersects with biological and cultural evolution. We briefly summarize the effects of infant carrying on physiological, epigenetic, and socio-emotional outcomes.
