Abstract It is an orthodoxy in cognitive science that perception can occur unconsciously. Recently, Hakwan Lau, Megan Peters and Ian Phillips have argued that this orthodoxy may be mistaken. They argue that many purported cases of unconscious perception fail to rule out low degrees of conscious awareness while others fail to establish genuine perception. This paper presents a case of unconscious perception that avoids these problems. It also advances a general principle of ‘phenomenal coherence’ that can insulate some forms of evidence for unconscious perception from the methodological critiques of Lau, Peters and Phillips.

Metaphor has traditionally been construed as a linguistic phenomenon: as something produced and understood by speakers of natural language. So understood, metaphors are naturally viewed as linguistic expressions of a particular type, or as linguistic expressions used in a particular type of way. This linguistic conception of metaphor is adopted in this article. In doing so, the article does not intend to rule out the possibility of non-linguistic forms of metaphor. Many theorists think that non-linguistic objects (such as paintings or dance performances) or conceptual structures (like love as a journey or argument as war) should also be treated as metaphors. Indeed, the idea that metaphors are in the first instance conceptual phenomena, and linguistic devices only derivatively, is the dominant view in what is now the dominant area of metaphor research: cognitive science. In construing metaphor as linguistic, the article merely intends to impose appropriate constraints on a discussion whose focus is the understanding and analysis of metaphor within contemporary philosophy of language.

Cognitive Attitudes

Several authors deny that the senses of agency and of bodily ownership have distinctive phenomenology. This is in line with a general principle of phenomenal parsimony, according to which one should not posit additional phenomenal properties in one’s mental ontology when one can explain them by appealing to other properties. The crucial question is then to determine what reasons there can be to enrich our phenomenal ontology. This debate has recently turned to cognitive science to find answers. Those who defend a liberal or rich view of phenomenology have taken pathological disorders and illusions as evidence in favor of the existence of a distinctive phenomenology, but even in these borderline cases there is room for interpretation, and where the liberals see feelings, the proponents of a more conservative view see cognitive attitudes. The argument then becomes an inference to the best explanation. But whose side offers the best explanation?

The Subject

Phenomenology as an approach emerges with the work of Edmund Husserl and was developed in original ways by Martin Heidegger, Jean-Paul Sartre, Maurice Merleau-Ponty, Alfred Schutz, and others, to become one of the major philosophical movements of the twentieth century. Phenomenology begins from the recognition that conscious life is intentional, that is, that all conscious awareness is directed at something, and that there is a complex correlation between the subjective act and the object apprehended, such that the object is said to be “constituted” by the subject. In order to lay bare this intentional constitution, phenomenologists apply a procedure of bracketing or phenomenological reduction that strips away presuppositions embedded in the natural attitude. Phenomenology has wide application not just in philosophy but in psychology and psychiatry. In recent years, phenomenology’s stress on the embodied character of life in the context of a life-world has had a major impact on cognitive science.

Abstract Gilead et al.'s approach to human cognition places abstraction and prediction at the heart of “mental travel” under a “representational diversity” perspective that embraces foundational concepts in cognitive science. But, it gives insufficient credit to the possibility that the process of abstraction produces a gradient, and underestimates the importance of a highly influential domain in predictive cognition: language, and related, the emergence of experientially based structure through time.

Canine distemper is a multisystemic contagious viral disease having a worldwide distribution, a high mortality rate, and significant central neurologic system (CNS) complications. In its systemic manifestations, it is often presumptively diagnosed on the basis of clinical signs and history. Few definitive antemortem diagnostic tests exist, and most are limited to the detection of viral antigen by immunofluorescence techniques on tissues or cytologic specimens or high immunoglobulin levels in CSF (cerebrospinal fluid). Diagnosis of CNS distemper is often unreliable due to the relatively low cell count in CSF (<50 cells/μl) and the binding of blocking immunoglobulins in CSF to cell surfaces. A more reliable and definitive test might be possible utilizing direct morphologic detection of the etiologic agent. Distemper is the canine equivalent of human measles, in that both involve a closely related member of the Paramyxoviridae, both produce mucosal inflammation, and may produce CNS complications. In humans, diagnosis of measles-induced subacute sclerosing panencephalitis is through negative stain identification of whole or incomplete viral particles in patient CSF.

Purpose Previous studies showed early production precedes late perception in Cantonese tone acquisition, contrary to the general principle that perception precedes production in child language. How tone production and perception are linked in 1st language acquisition remains largely unknown. Our study revisited the acquisition of tone in Cantonese-speaking children, exploring the possible link between production and perception in 1st language acquisition. Method One hundred eleven Cantonese-speaking children aged between 2;0 and 6;0 (years;months) and 10 adolescent reference speakers participated in tone production and perception experiments. Production materials with 30 monosyllabic words were transcribed in filtered and unfiltered conditions by 2 native judges. Perception accuracy was based on a 2-alternative forced-choice task with pictures covering all possible tone pair contrasts. Results Children's accuracy of production and perception of all the 6 Cantonese tones was still not adultlike by age 6;0. Both production and perception accuracies matured with age. A weak positive link was found between the 2 accuracies. Mother's native language contributed to children's production accuracy. Conclusions Our findings show that production and perception abilities are associated in tone acquisition. Further study is needed to explore factors affecting production accuracy in children.

Abstract Symptom validity testing, also known as forced-choice testing, is a way to assess the validity of sensory and memory deficits, including tactile anesthesias, paresthesias, blindness, color blindness, tunnel vision, blurry vision, and deafness—the common feature of which is a claimed inability to perceive or remember a sensory signal. Symptom validity testing comprises two elements: A specific ability is assessed by presenting a large number of items in a multiple-choice format, and then the examinee's performance is compared with the statistical likelihood of success based on chance alone. Scoring below a norm can be explained in many different ways (eg, fatigue, evaluation anxiety, limited intelligence, and so on), but scoring below the probabilities of chance alone most likely indicates deliberate deception. The positive predictive value of the symptom validity technique likely is quite high because there is no alternative explanation to deliberate distortion when performance is below the probability of chance. The sensitivity of this technique is not likely to be good because, as with a thermometer, positive findings indicate that a problem is present, but negative results do not rule out a problem. Although a compelling conclusion is that the examinee who scores below probabilities is deliberately motivated to perform poorly, malingering must be concluded from the total clinical context.

Abstract A diagnosis of toxic-related injury/illness requires a consideration of the illness related to the toxic exposure, including diagnosis, causation, and permanent impairment; these are best performed by a physician who is certified by a specialty board certified by the American Board of Preventive Medicine. The patient must have a history of symptoms consistent with the exposure and disease at issue. In order to diagnose the presence of a specific disease, the examiner must find subjective complaints that are consistent with the objective findings, and both the subjective complaints and objective findings must be consistent with the disease that is postulated. Exposure to a specific potentially causative agent at a defined concentration level must be documented and must be sufficient to induce a particular pathology in order to establish a diagnosis. Differential diagnoses must be entertained in order to rule out other potential causes, including psychological etiology. Furthermore, the identified exposure at the defined concentration level must be capable of causing the diagnosis being postulated before the examiner can conclude that there has been a cause-and-effect relationship between the exposure and the disease (dose-response relationship). The evaluator's opinion should make biological and epidemiological sense. The treatment plan and prognosis should be consistent with evidence-based medicine, and the rating of impairment must be based on objective findings in involved systems.
