Creativity,chaos, and self‐renewal in human systems

The research findings from the psychology of creativity are shown to be of considerable relevance to the study of self‐organization and self‐renewal in human systems. The characteristics of the creative person, and the nature of the creative process, particularly as they have been elaborated by Barron, are shown to be remarkably congruent with recent findings and theoretical elaborations by Abraham, Jantsch, Laszlo, Prigogine, and others in the fields of evolutionary and chaos theory. The broader social implications of chaos and evolutionary theories are fleshed out through an understanding of their characteristics in creative human systems.     

Loss, trauma, and human resilience: have we underestimated the human capacity to thrive after extremely aversive events?

Many people are exposed to loss or potentially traumatic events at some point in their lives, and yet they continue to have positive emotional experiences and show only minor and transient disruptions in their ability to function. Unfortunately, because much of psychology's knowledge about how adults cope with loss or trauma has come from individuals who sought treatment or exhibited great distress, loss and trauma theorists have often viewed this type of resilience as either rare or pathological. The author challenges these assumptions by reviewing evidence that resilience represents a distinct trajectory from the process of recovery, that resilience in the face of loss or potential trauma is more common than is often believed, and that there are multiple and sometimes unexpected pathways to resilience.     

Imagining human enhancement: whose future,which rationality?

This article critically evaluates bettering human life. Because this involves lives that do not exist yet, the article investigates human eugenics and enhancement through the social prism of ‘the imaginary’ (defined ‘as a set of assumptions and concepts for thinking and speaking about human enhancement and its future direction’) [1]. “Exploring basic assumptions underlying the idea of human enhancement” investigates underlying assumptions and claims for human enhancement. Firstly, human eugenics and enhancement entangles a factual as well as a normative claim about what improvement/betterment maybe constitutive of. Secondly, claims about what a better life is, is often a future orientated claim about whether certain kinds of life that do not exist yet should ever exist. Moral images of thought are introduced and how they work to make normative judgments about lives that do not exist. This implicates the moral problem of difference, where an image of a ‘better’ life—classically expressed in eugenics as a ‘superior’ and/or ‘normal’ life—necessarily entails inferiority and/or deviance from a norm. “Moral imagination in contemporary fiction and the history of old eugenics”, introduces moral images in history of eugenics and demonstrates how examples fall foul of the problem. “The new (liberal) eugenics and the moral image of therapy” examines progress in contemporary debates, the move from authoritarian to non-authoritarian eugenics (human enhancement), and how, to some extent, this has solved the problem of difference, through liberal defence of personal choice. “The heart of the eugenic issue” suggests that personal choice in liberal non-authoritarian eugenics is not immune to basic drive behind all eugenic arguments; desire as lack which is expressed as the continual dissatisfaction of not having our future expectations met.

Are Caribbean reef sharks,Carcharhinus perezi,able to perceive human body orientation?

The present study examines the potential capability of Caribbean reef sharks to perceive human body orientation, as well as discussing the sharks’ swimming patterns in a person’s vicinity. A standardized video method was used to record the scenario of single SCUBA divers kneeling in the sand and the approach patterns of sharks, combined with a control group of two divers kneeling back-to-back. When approaching a single test-subject, significantly more sharks preferred to swim outside the person’s field of vision. The results suggest that these sharks are able to identify human body orientation, but the mechanisms used and factors affecting nearest distance of approach remain unclear.     

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.     

Imitation, pretend play, and childhood: essential elements in the evolution of human culture?

There is much controversy over what is needed for culture to flourish and what has led human culture to be different from "cultural" characteristics of other animals. Here I argue that the emergence of childhood as a step in the life cycle was critical to the evolution of the human cultural mind. My line of reasoning is built around two complementary features of childhood: imitation and play. When children imitate adults they routinely copy unnecessary and arbitrary actions. They will persistently replicate how an object is used, even when doing so interferes with their ability to produce the very outcome those actions are intended to bring about. Though seemingly maladaptive, this behavior provides for the faithful transmission of cultural ideas across generations. When children play together they commonly construct rules and meanings that exist purely because the players agree they "exist." Play thus provides the building blocks with which children rehearse the kinds of institutional realities that typify cultural practices. I argue that these forms of imitation and play represent a foundation upon which human culture flourished and that neither are prevalent in nonhuman animals. In light of these arguments evidence will be assessed suggesting that childhood emerged relatively late in human evolution.     

Where did you go wrong? Errors, partial errors, and the nature of human information processing

Human performance is seldom perfect, and even when an overt response is correct it may be accompanied by partial-error activity that does not achieve the level of a complete incorrect response. Partial errors can be detected in measures of the lateralized readiness potential, of the electromyogram, and of response force. Correct responses accompanied by partial errors tend to have slower reaction times than “clean” correct responses (because of response competition), and condition differences in reaction time can, on some occasions, be explained in terms of differences in the incidence of partial errors. In two-choice reaction time tasks, partial errors are more frequent when the imperative stimulus contains information that favors both responses, than when it contains information that favors only one response. The non-random nature of partial errors supports the inference that partial information about the stimulus is used to guide responses. A similar inference is supported by the observation that, in hybrid choice Go/No-go tasks, the kinds of partial errors that follow a No-go stimulus represent activation of the response that would have been correct had the stimulus been a Go stimulus. Finally, we note that the human processing system is capable of monitoring its own behavior and of initiating remedial actions if necessary. The activity of an error-detection system, as revealed by measures of the error-related negativity, is related to the degree to which responses are slowed after errors.     

Examining dog–human play: the characteristics,affect, and vocalizations of a unique interspecific interaction

Despite the growing interest in research on the interaction between humans and dogs, only a very few research projects focus on the routines between dogs and their owners. In this study, we investigated one such routine: dog–human play. Dyadic interspecific play is known to be a common interaction between owner and charge, but the details of what counts as play have not been thoroughly researched. Similarly, though people represent that “play” is pleasurable, no study has yet undertaken to determine whether different forms of play are associated with different affective states. Thus, we aimed to generate an inventory of the forms of dyadic play, the vocalizations within play, and to investigate the relationship of affect to elements of play. Via a global citizen science project, we solicited videotapes of dog–human play sessions from dog owners. We coded 187 play bouts via frame-by-frame video playback. We then assessed the relationship between various intra-bout variables and owner affect (positive or neutral) during play (dog affect was overwhelmingly positive). Amount of physical contact (“touch”), level of activity of owner (“movement”), and physical closeness of dog–owner dyad (“proximity”) were highly correlated with positive affect. Owner vocalizations were found to contain different elements in positive- and neutral-affect play. One novel category of play, “tease”, was found. We conclude that not all play is created equal: the experience of play to the owner participant is strongly related to a few identifiable characteristics of the interaction.     

Are transitions in human gait determined by mechanical,kinetic or energetic factors?

It is currently unclear whether it is the need to maintain metabolic efficiency, the need to keep skeletal loading below critical force levels, or simple mechanical factors that drive the walk-to-run (W-R) and run-to-walk (R-W) transitions in human gait. Eighteen adults (9 males and 9 females) locomoted on an instrumented treadmill using their preferred gait. Each completed 2 ascending (W-R) and 2 descending (R-W) series of trials under three levels of loading (0%, 15% and 30% body weight). For each trial, participants locomoted for 60 s at each of 9 different speeds--4 speeds both above and below their preferred transition speed (PTS) plus their PTS. Evidence was sought for critical levels of key kinetic (maximum vertical force, impulse, first peak force, time to first peak force and maximum loading rate), energetic (oxygen consumption, transport cost) and mechanical variables (limb lengths, strength) predictive of the gait transition. Analyses suggested the kinetic variables of time to first peak force and loading rate as the most likely determinants of the W-R and R-W transitions.     

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.

Infrahumanization or familiarity? Attribution of uniquely human emotions to the self, the ingroup, and the outgroup

People attribute more secondary emotions to their ingroup than to outgroups. This effect is interpreted in terms of infrahumanization theory. Familiarity also could explain this differential attribution because secondary emotions are thought to be less visible and intense than primary ones. This alternative explanation to infrahumanization was tested in three studies. In Study 1, participants attributed, in a between-participants design, primary and secondary emotions to themselves, to their ingroup, or to an outgroup. In Study 2, participants answered for themselves and their ingroup or for themselves and an outgroup. In Study 3, participants made attributions to the ingroup or a series of outgroups varying in terms of familiarity. The data do not support an explanation in terms of familiarity. The discussion centers on conditions not conducting to infrahumanization.     

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

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.
