Showing papers in "Consciousness and Cognition in 2000"

TL;DR: A developmental approach to the organization of the anatomy involved in executive control provides an added perspective on how these mechanisms are influenced by maturation and learning, and how they relate to metacognitive activity.

TL;DR: A model of anesthetic-induced unconsciousness is introduced to explain how the plethora of effects anesthetics have on cellular functioning ultimately all converge on a single neuroanatomic/neurophysiologic system, thus providing for a unitary physiologic theory of narcosis related to consciousness.

TL;DR: Examination of the cues that affect noetic feelings suggest that not only do these feelings inform controlled action, but they are also informed by feedback from the outcome of that action.

TL;DR: An evaluation of the proposal by Fernandez-Duque et al. is made, and it is suggested that there is considerable convergence of issues associated with metacognition, executive control, working memory, and frontal lobe function.

TL;DR: The 17-item Revised Transliminality Scale (or RTS) is presented that corrects age and gender biases, is unidimensional by a Rasch criterion, and has a reliability of.

TL;DR: This paper aims to critically review the EC literature and to draw some parallels to what is known about autonomic conditioning and some important general issues about measuring contingency awareness are raised.

TL;DR: An empirically motivated theory of visual consciousness is developed that supplements neuropsychological support for Jackendoff's (1987) hypothesis that visual consciousness involves mental representations at an intermediate level of processing with the further requirement that attention, which can come under the direction of high level representations, is also necessary for consciousness.

TL;DR: Having metacognitive access to information carried by states that are not conscious helps confirm the hypothesis that a mental state's being conscious consists in having a noninferential higher-order thought about that state.

TL;DR: It is argued that phenomenology can be linked to psychology and neuroscience and a meaningful way that illuminates both.

TL;DR: This issue welcomes Shimamura's extension of the concept of metacognitive regulation to include aspects of working memory, and its relation to executive attention.

TL;DR: It is concluded that, in masked priming, response codes are automatically activated by stimulus characteristics of the prime and that the activation of response codes is semantically mediated when the primes are meaningful.

TL;DR: A recently published study is described in which a blindsight subject could change the schema with which he processed cue information in orienting spatial attention task without reporting any awareness of this change, or of the cues and targets which respectively directed and were the object his attention.

TL;DR: In this rejoinder, several issues raised by the commentators are clarified and the distinction between information-based and experience-based metacognitive judgments and the idea that memory monitoring may be mediated by direct access to internal representations are addressed.

TL;DR: A cluster of issues that have to do with the status, motivation, and exact formulation of the higher-order-thought (HOT) hypothesis independent of questions about metacognition are addressed.

TL;DR: When comparing the cognitive variables between the two groups, reflective consciousness was clearly highest in narcoleptics, whereas improbabilities and discontinuities were lower, with mentation report length and visual vividness differing less between the groups.

TL;DR: The results from the first three experiments showed that when instructions induce weak preparatory attention to the target location, response times to a target on target-only trials increase substantially as the percentage of trials containing a distractor increases from 0 to 75%.

TL;DR: Asymmetrical arrangement of stimuli has an impact on the allocation of attention, but only in the RT task, and dissociations between TOJ and response times cannot be accounted for by an attentional bias in the TOJ task but probably by different use of temporal information in the two tasks.

TL;DR: A case is made for further consideration of the scientific merits of the direct-access view of the noetic feelings people experience in imminent tip-of-the-tongue (TOT) states.

TL;DR: Possible systemic effects of general anesthetic agents on neural information processing are discussed in the context of the thalamocortical suppression hypothesis presented by Drs.

TL;DR: It is suggested that cognitive binding is a distinct mental state that is reliably induced by ambiguous-figure perception tasks and coherent oscillations at multiple frequencies may reflect the mechanism by which such binding occurs.

TL;DR: The research on feeling of knowing will not resolve the question of whether consciousness is merely epiphenomenal, and this work agrees that feelings of knowing are produced through a monitoring of one's knowledge, and that this monitoring can affect the control of behavior.

TL;DR: Brown’s article helps us see, the theoretical implications of a TOT experience range very widely and offers an especially good example of convergent cognitive analysis, a way to combine phenomenology with more objective methods of scientific investigation such as experimental psychology and computer modeling.

TL;DR: A hierarchical system of neural structures that regulate water conservation and acquisition is proposed and it is proposed that the awareness of thirst in rodents is either entirely or predominantly due to neuronal activities in a subsection of the ventrolateral periaqueductal gray matter.

TL;DR: It is proposed that, even in humans, there is a period in early infancy when visual awareness is partially due to activities in the superior colliculus, but that this awareness gradually disappears as the nigrotectal projection matures.

TL;DR: Dans l'article suivant qui constitue une reponse au commentaire de Hammerl, A. P. Field conclut en montrant que sa propre conception du conditionnement evaluatif s'apparente a l'apprentissage de Pavlov.

TL;DR: An explanation of the ineffability (linguistic inexpressibility) of sensory experiences is offered in terms of computational functionalism and standard externalist theories of representational content.

TL;DR: The critical reinterpretations of Libet's research by G. Gomes make speculative, unwarranted, and untested assumptions and their status relative to Libet’s findings is criticized.

TL;DR: The available evidence supports Field's proposition that EC is, in fact, Pavlovian learning and the article concludes that the available evidence support Field's propositions that EC uniformly occurs in the absence of contingency awareness.

TL;DR: It is suggested that in contrast to schizophrenia, agency and spatial perspectivity are probably preserved in autism, but that, similarly to schizophrenic, long-term unity is probably impaired.

TL;DR: It is argued that James's concept of the phenomenon of fringes provides a structural framework from which to investigate and better understand ideas and concepts that are indeterminate, particularly those experienced in the sense of being sought-after.
