The effect of running speed on joint coupling coordination and its variability in recreational runners

The purpose of this study was to examine the effect of speed on coordination and its variability in running gait using vector coding analysis. Lower extremity kinematic data were collected for thirteen recreational runners while running at three different speeds in random order: preferred speed, 15% faster and 15% lower than preferred speed. A dynamical systems approach, using vector coding and circular statistics, were used to quantify coordination and its variability for selected hip-knee and knee-ankle joint couplings. The influence of running speed was calculated from the continuous data sets of the running cycle, allowing for the identification of time percentages where differences existed. Results indicate that increases in running speed produced moderate alterations in the frequency of movement patterns which were not enough to alter classification of coordination. No effects of speed on coordination variability were observed. This study has demonstrated that coordination and coordination variability is generally stable in the range of ±15% around of preferred speed in recreational runners.     

The CORTEX cognitive robotics architecture: Use cases

CORTEX is a cognitive robotics architecture inspired by three key ideas: modularity, internal modelling and graph representations. CORTEX is also a computational framework designed to support early forms of intelligence in real world, human interacting robots, by selecting an a priori functional decomposition of the capabilities of the robot. This set of abilities was then translated to computational modules or agents, each one built as a network of software interconnected components. The nature of these agents can range from pure reactive modules connected to sensors and/or actuators, to pure deliberative ones, but they can only communicate with each other through a graph structure called Deep State Representation (DSR). DSR is a short-term dynamic representation of the space surrounding the robot, the objects and the humans in it, and the robot itself. All these entities are perceived and transformed into different levels of abstraction, ranging from geometric data to high-level symbolic relations such as “the person is talking and gazing at me”. The combination of symbolic and geometric information endows the architecture with the potential to simulate and anticipate the outcome of the actions executed by the robot. In this paper we present recent advances in the CORTEX architecture and several real-world human-robot interaction scenarios in which they have been tested. We describe our interpretation of the ideas inspiring the architecture and the reasons why this specific computational framework is a promising architecture for the social robots of tomorrow.

THE MISSING FATHER FUNCTION IN PSYCHOANALYTIC THEORY AND TECHNIQUE: THE ANALYST'S INTERNAL COUPLE AND MATURING INTIMACY

This paper argues that recovering the “missing” paternal function in analytic space is essential for the patient's achievement of mature object relations. Emerging from the helpless infant's contact with primary caregivers, mature intimacy rests on establishing healthy triadic functioning based on an infant‐with‐mother‐and‐father. Despite a maternocentric bias in contemporary clinical theory, the emergence of triangularity and the inclusion of the paternal third as a separating element is vital in the analytic dyad. Effective technique requires the analyst's balanced interplay between the paternal, investigative and the maternal, maximally receptive modes of functioning—the good enough analytic couple within the analyst—to serve as the separating element that procreatively fertilizes the capacity for intimacy with a differentiated other. A clinical example illustrates how treatment is limited when the paternal function is minimized within more collusive, unconsciously symbiotic dyads.     

Generalized and specific components of prejudice: The decomposition of intergroup context effects

Although different types of prejudice tend to be highly correlated, target‐specific and more generalized components can nevertheless be distinguished. Here, we analyze whether indicators of the intergroup context—threat, contact, and neighborhood composition—predict the target‐specific and/or generalized components of prejudice. Using data from the New Zealand Attitudes and Values Study (N = 4629), we build a multilevel model that captures the relationship between social dominance orientation, general levels of neighborhood heterogeneity, symbolic and realistic threat and cross‐group friendship (averaged across target groups), and generalized prejudice. Our model simultaneously estimates the relationship between target‐specific levels of these intergroup context indicators and target‐specific prejudice. Results indicated that social dominance orientation remained the strongest predictor of generalized prejudice when adjusting for other variables and that indicators of the intergroup context primarily explain differences between target group ratings. Aggregate levels of cross‐group friendship also had a small effect on generalized prejudice.     

Fear of Infection or Justification of Social Exclusion? The Symbolic Exploitation of the Ebola Epidemic

Public discourse in Western countries on the 2014 Ebola epidemic provided a unique natural opportunity to study the relationship between a disease's sociocultural representation and health policy support. Our main prediction stated that among Western citizens, support for restrictive health policies (e.g., mandatory quarantining) would be determined more through preexisting prejudice towards African immigrants than fears of Ebola infection. A questionnaire study with time‐lagged measurement of predictor and criterion variables employing a German sample (N = 218) that was heterogeneous in terms of gender, age, profession, political orientation, and income level provided clear support for this assumption. Although variables related to fear‐of‐infection were significant predictors, prejudice‐related variables explained several times more variance in participants’ support for restrictive policies. Moreover, the degree to which participants adopted prevalent beliefs regarding the sociocultural origins of Ebola (e.g., eating bushmeat) further intensified the impact of prejudice‐related variables.     

不同群际威胁类型对集体自尊的影响:愤怒和自卑的中介作用

现有研究中有关群际威胁对集体自尊是增强作用还是削弱作用存在矛盾结论,可能是不同研究采用了不同类型的群际威胁,且情绪在群际威胁和集体自尊二者之间可能存在某种作用所导致的。本研究通过情景启动的实验发现,现实群际威胁唤起了更高水平的愤怒情绪,愤怒情绪越多,被试的集体自尊越高。而象征群际威胁唤起了更高水平的自卑情绪,自卑情绪越多,被试的集体自尊越低。总之,群际威胁类型的不同对集体自尊产生不同的影响,情绪在其中起中介作用。     

Relational learning in children with deafness and cochlear implants

This four-experiment series sought to evaluate the potential of children with neurosensory deafness and cochlear implants to exhibit auditory-visual and visual-visual stimulus equivalence relations within a matching-to-sample format. Twelve children who became deaf prior to acquiring language (prelingual) and four who became deaf afterwards (postlingual) were studied. All children learned auditory-visual conditional discriminations and nearly all showed emergent equivalence relations. Naming tests, conducted with a subset of the children, showed no consistent relationship to the equivalence-test outcomes. This study makes several contributions to the literature on stimulus equivalence. First, it demonstrates that both pre- and postlingually deaf children can acquire auditory-visual equivalence relations after cochlear implantation, thus demonstrating symbolic functioning. Second, it directs attention to a population that may be especially interesting for researchers seeking to analyze the relationship between speaker and listener repertoires. Third, it demonstrates the feasibility of conducting experimental studies of stimulus control processes within the limitations of a hospital, which these children must visit routinely for the maintenance of their cochlear implants.     

CASH only: Constitutive autonomy through motorsensory self-programming

Constitutive autonomy is the capacity of an entity to perpetually develop its individual constitution and coupling with its environment. We argue that computational entities (i.e., entities that can perform computation) can gain constitutive autonomy through motorsensory self-programming – a mechanism by which the entity acquires new computational processes as a series of patterns of interaction that the entity can learn through experience, simulate internally, and enact in the environment. Motorsensory self-programming allows the evolution of the cognitive coupling between the entity’s behavior selection mechanism and the environment as it appears from the viewpoint of the behavior selection mechanism. Constitutive autonomy of computational entities could lead to genuine agency.
