To Die or Not to Die: Zhuangzi’s Three Immortalities

While it is known that the problem of death is a central topic animating the author/s of the Inner Chapters of the Zhuangzi, leading Chinese and Western interpretations of this Chinese classic have usually focused much more on other themes and aspects. Even more problematic in the author’s view is the fact that the Zhuangzi has been closely associated with one death philosophy, the set of concepts, arguments and figures present in chapter 6. This study puts death back at the very center of the Zhuangzian philosophical project yet insisting at the same time on the difficulties of defending one philosophy of death since different passages introduce new concepts, imagery, nuances and perspectives. The Zhuangzi’s focus on death is being situated within a discussion of the “immortality” ideal––accepting a total death (“to die”) or find refuge in immortality ideals (“not to die”). Different passages from the Inner Chapters are being presented as proposing three distinct immortality projects or strategies––personal, social and cosmic––to address the problem of death. E. Becker’s reflections on the challenge of mortality and the psychological need of a “beyond” in order to cope with the consciousness of death provide the basic theoretical framework underlying the discussion of the Zhuangzi in this essay.     

Contextual control of inhibition with reinforcement: adaptation and timing mechanisms

Four experiments with rats studied the effects of switching the context after Pavlovian conditioning. In three conditioned suppression experiments, a large number of conditioning trials created "inhibition with reinforcement" (IWR), in which fear of the conditional stimulus (CS) reached a maximum and then declined despite continued CS-unconditional stimulus pairings. When IWR occurred, a context switch augmented fear of the CS; IWR and augmentation were highly correlated. Neither IWR nor augmentation resulted from inhibition of delay (IOD): In conditioned suppression, IWR and augmentation occurred without IOD (Experiment 3), and in appetitive conditioning (Experiment 4), IOD occurred without IWR or augmentation. IWR may occur in conditioned suppression because the animal adapts to fear of the CS in a context-specific manner. The authors discuss several implications.     

Constrained action selection in children with developmental coordination disorder

The effect of advance ('precue') information on short aiming movements was explored in adults, high school children, and primary school children with and without developmental coordination disorder (n=10, 14, 16, 10, respectively). Reaction times in the DCD group were longer than in the other groups and were more influenced by the extent to which the precue constrained the possible action space. In contrast, reaction time did not alter as a function of precue condition in adults. Children with DCD showed greater inaccuracy of response (despite the increased RT). We suggest that the different precue effects reflect differences in the relative benefits of priming an action prior to definitive information about the movement goal. The benefits are an interacting function of the task and the skill level of the individual. Our experiment shows that children with DCD gain a benefit from advance preparation in simple aiming movements, highlighting their low skill levels. This result suggests that goal-directed RTs may have diagnostic potential within the clinic.     

Gricean Communication and Transmission of Thoughts

Gricean communication is communication between utterers and their audiences, where the utterer means something and the audience understands what is meant. The weak transmission idea is that, whenever such communication takes place, there is something which is transmitted from utterer to audience; the strong transmission idea adds that what is transmitted is nothing else than what is communicated. We try to salvage these ideas from a seemingly forceful attack by Wayne Davis. Davis attaches too much significance to the surface structure of sentences of the type ‘S communicates the belief (desire …) that p to A’ by assuming that the communicated entity is denoted by the grammatical object following ‘communicates’. On our proposal, what is communicated in all Gricean cases is a thought. And since S communicates the thought that p to A only if S means that p and A understands what S means, the thought that p will be transmitted from S to A.     

Social Ontology as Convention

I will argue that social ontology is constituted as hierarchical and interlocking conventions of multifarious kinds. Convention, in turn, is modeled in a manner derived from that of David K. Lewis. Convention is usually held to be inadequate for models of social ontologies, with one primary reason being that there seems to be no place for normativity. I argue that two related changes are required in the basic modeling framework in order to address this (and other) issue(s): (1) a shift to an intentional model—among other reasons, in order to account for normativity—and (2) moving away from the belief-desire, propositional attitude, framework for understanding the intentional realm toward an interactive, pragmatic model of intentionality. These shifts provide natural approaches to: (1) understanding the normativities of social realities; (2) the sense in which social ontology is often constituted in implicit relations among the participants rather than elaborated and iterated explicit beliefs and desires; (3) and language.     

The association of parenting style and child age with parental limit setting and adolescent MySpace behavior

Parent and teen MySpace user pairs completed online surveys administered in June (N = 266) and September 2006 (N = 341) to assess relationships between parenting styles and limit setting and monitoring of online behaviors, the prevalence of Internet dangers and pre-teen and teen MySpace behaviors. Cross-comparison measures of MySpace usage, parenting style, limit setting/monitoring, MySpace problems, and media perceptions were used. Parenting styles were strongly related to adolescent MySpace experiences, behaviors, and attitudes, with some age differences. Parents with older children were more likely to have Neglectful or Indulgent parenting styles and less likely to set limits on online behavior. The extent of sexual solicitation, pornography, and cyberbullying was relatively low as compared with studies asserting a high incidence of Internet-related problems. Parents' high estimates of online dangers were not matched by their low rates of setting limits and monitoring teens. Theoretical and practical perspectives of the results are offered to enhance social networking experiences for parents and their children.     

Emotional competence in children with autism: Diagnostic criteria and empirical evidence

The diagnostic criteria of autism spectrum disorders (ASD) include emotional impairments. However, scientific evidence for these impairments is varied and subtle. In this contribution, recent empirical studies that examined the emotional competence in children and adolescents with ASD are reviewed. Four aspects of emotional competence that are important to children’s daily social functioning (expression, perception, responding, and understanding) are discussed, differentiating between mentally retarded and normally intelligent children and adolescents with and without ASD in natural and structured contexts. On various accounts, the emotional impairments of children with ASD that are found in scientific studies provide a more differentiated view on the impairments suggested by the diagnostic literature. Consistent empirical findings and gaps in the field are discussed. Theoretical and clinical recommendations for assessment procedures are suggested.     

Reducing contrast makes speeds in a video-based driving simulator harder to discriminate as well as making them appear slower

We investigated the effect of reducing image contrast on speed perception using a video-based driving simulator in which participants viewed pairs of scenes and were asked to judge whether the second scene was faster or slower than the first scene. We predicted two outcomes: (i) that vehicle speeds would become harder to discriminate, and (ii) that vehicle speeds would appear slower. There is previous evidence confirming the latter prediction in a less realistic computer-based driving simulation, but none demonstrating the former. Our results supported both predictions, each of which may have traffic-safety implications when reduced-contrast conditions are experienced in real life, such as with fog or when the driver has cataracts.     

What is the reference in reference repulsion?

Reference repulsion is a mechanism posited to explain systematic biases of direction judgment of single drifting dot displays (Rauber and Treue, 1998 Perception 27 393-402). Rauber and Treue obtained systematic but, surprisingly, very different effects depending upon whether standard and comparison stimuli were presented simultaneously or successively. Successive effects were described as exhibiting repulsion from both vertical and horizontal cardinal axes, whereas simultaneous effects showed repulsion from horizontal only. We contend that the proposed mechanism makes no testable predictions because the so-called reference can only be specified a posteriori, a fact acknowledged by Rauber and Treue. We attempted to replicate Rauber and Treue's experiments, but we obtained no systematic biases of direction judgment. Comparisons across several studies suggest that errors in direction judgments of single drifting dot patterns vary widely in magnitude and direction, as might be expected with what are essentially baseline or pretest measures. In our view, reference repulsion describes neither a real perceptual mechanism nor a predictable pattern of direction misjudgments.
