The distinction between conscious and unconscious cognition in David R. Shanks’s work: A critical assessment

Abstract The notion of unconscious finds support in many experimental studies that use the dissociation method. This method allows us to distinguish between conscious and unconscious mental states when participants cannot explain why they performed as they did in an experiment. The paper will discuss the notion of unconscious by considering David R. Shanks’ criticisms of the application of the dissociation method: it will assess three studies Shanks proposes as reexaminations of three other relevant studies in the literature and show how Shanks’ work provides an examination of the methodological pitfalls of such studies. The paper will argue that, although Shanks’s results are relevant regarding theories about the structure of cognition, his theoretical positions are at best confused and at worst diminish the importance of his research outcomes. It will conclude by showing why Shanks’s results that legitimize the role of consciousness in cognition can be problematic for the physicalistic or materialistic framework endorsed by cognitive psychologists.Keywords: Dissociation Method; Dual-process Theories; Cognitive Psychology; Consciousness; UnconsciousLa distinzione tra cognizione conscia e inconscia nell’opera di D.R.

The Relationship between Introspection and Folk Psychology: An Overview

The epistemic status of introspection remains a controversial topic. due to its subjective char- acter, introspection is not an easy fit with natural sciences or a physicalistic picture of the mind. In literature, introspection is conceived as dealing only with macro-cognition and not with micro-cognition, the supposed object of study of scientific psychology. This essay dis- cusses the epistemic status of introspection in light of its relationship with folk psychology and spells it out through an analysis of the positions of Wilkes, Alston, Schwitzgebel, and Churchland. Specifically, the essay makes a distinction between folk and scientific psychol- ogy and addresses the issue of the incorrigibility/infallibility of introspective judgments. The essay endorses a view according to which introspection should be conceived as a cognitive process the contents of which are provided by folk knowledge. It shows how this view can be appreciated as scientific, provided that a physicalistic image of the mind is rejected

Science, Scientism, and the Disunity of Science: Popular Science during the COVID-19 Pandemic

Unsurprisingly, science has been conferred growing expectations in the context of the COVID-19 pandemic. Accordingly, the issue of dissemination and popularization of scientific outcomes has come to the fore. The article describes the main features of the so-called dominant view in popular science, which is claimed to be implicitly connected to scientism, a stance identifying science as the most (if not the only) reliable source of legitimate knowledge. Scientism’s implicit philosophical roots are argued to lie in naturalism and a trivialized neopositivist concept of science, which underscores the supposed unity of the scientific enterprise. However, in the context of the pandemic, science’s disunity is more than ever visible. It is herein asserted that the untimely glimpse into science’s inner workings, clashing with the dominant view in popular science, promotes a distorted image of science and hinders people’s trust in science. Finally, this article provides wide-ranging recommendations in order to tackle scientism and promote a balanced outlook on science in the fodder consumed by the masses

Early onset Mirror Syndrome associated with foetal sacrococcigeal teratoma: a rare entity

In the mirror syndrome, maternal symptoms mime foetal and placental oedema. The pathogenesis is unknown. The most common etiologic associations are rhesus isoimmunization, twin-twin transfusion syndrome and viral infections. Few reports are associated to foetal tumors and particularly to sacroccoccigeal teratoma (SCT). Based on several published series, foetal SCT with placentomegaly and hydrops is almost universally fatal; foetal surgery is not typically offered for hydropic foetuses beyond 26 weeks of gestational age. Delivery of the foetus is the choise treatment when mirror syndrome is present with supporting the pregnancy until delivery is necessary for maternal indications or the foetus is 30 weeks old. The management of a patient with large foetal sacrococcygeal teratoma, hydrops foetalis and early onset mirror syndrome is presented

Mercury Detection in Benthic and Pelagic Fish Collected from Western Sicily (Southern Italy)

In highly polluted water, fish can accumulate mercury up to a concentration of 10 mgKg-1. This has occurred on the eastern coasts of Sicily (Southern Italy), probably due to the intense industrial activity of this area. However, little is known about Hg accumulation in fish of the western Sicilian coasts. In this work, we examined the Hg accumulation of 108 fish samples belonging to 14 species collected from western Sicilian coasts using a direct mercury analyzer. The samples showed a mean mercury concentration of 0.165 ± 0.22 mg kg-1 with a maximum in Lepidopus caudatus (1.72 mgKg-1), exceeding the limits provided by EC Reg. 1881/2006. The lowest Hg levels were found in Sparus aurata samples (0.001 mgKg-1). A significant difference was found between the fish species examined (p < 0.05). The comparison between benthic and pelagic species did not show statistical differences (p < 0.05). Fish food constitutes the main route of Hg uptake for humans. Only four of the 130 samples examined reached a mercury concentration over the European limits. The comparative analysis of Hg pollution for benthic and pelagic species did not confirm a different trend in metal contamination

Immunotherapy for recurrent ovarian cancer: a further piece of the puzzle or a striking strategy?

Introduction: Treatment of ovarian cancer has been long standardized with the inclusion of surgery and chemotherapy based on platinum and taxanes, this strategy reaching high remission rates. However, when this treatment fails, further options are available with little benefit. Since ovarian cancer has specific immunologic features, actually immunotherapy is under evalua- 15 tion to overcome treatment failure in patients experiencing recurrence. Areas covered: Immunogenicity of ovarian cancer and its relationship with clinical outcomes is briefly reviewed. The kinds of immunotherapeutic strategies are summarized. The clinical trials investigating immunotherapy in recurrent ovarian cancer patients are reported. 20 Expert opinion: The results of these clinical trials about immunotherapy are interesting, but little clinical benefit has been achieved until now. For this reason, we could conclude that immunotherapy is quite different from other treatment options and it could change the global approach for recurrent ovarian cancer treatment. However, to date only fragmentary findings are 25 available to define the real role of immunotherapy in this setting

Analysis of Germline Gene Copy Number Variants of Patients with Sporadic Pancreatic Adenocarcinoma Reveals Specific Variations

Objectives: The rapid fatality of pancreatic cancer is, in large part, the result of diagnosis at an advanced stage in the majority of patients. Identification of individuals at risk of developing pancreatic adenocarcinoma would be useful to improve the prognosis of this disease. There is presently no biological or genetic indicator allowing the detection of patients at risk. Our main goal was to identify copy number variants (CNVs) common to all patients with sporadic pancreatic cancer. Methods: We analyzed gene CNVs in leukocyte DNA from 31 patients with sporadic pancreatic adenocarcinoma and from 93 matched controls. Genotyping was performed with the use of the GeneChip Human Mapping 500K Array Set (Affymetrix). Results: We identified 431 single nucleotide polymorphism (SNP) probes with abnormal hy-bridization signal present in the DNA of all 31 patients. Of these SNP probes, 284 corresponded to 3 or more copies and 147 corresponded to 1 or 0 copies. Several cancer-associated genes were amplified in all patients. Conversely, several genes supposed to oppose cancer development were present as single copy. Conclusions: These data suggest that a set of 431 CNVs could be associated with the disease. This set could be useful for early diagnosis

Tetracycline Residues in Bovine Muscle and Liver Samples from Sicily (Southern Italy) by LC-MS/MS Method: A Six-Year Study

We examined a total of 369 bovine liver and muscle samples for the detection of oxytetracycline (OTC), tetracycline (TC), chlortetracycline (CTC), and doxycycline (DOX) residues by implementation and validation of a LC-MS/MS method. The method showed good recovery values between 86% and 92% at three levels of concentrations. The linearity tests revealed r2 > 0.996 for all the tetracyclines examined. Furthermore, the Youden test revealed that the method was robust. Only 14.4% of the samples showed OTC and TC residues in a concentration range of 10.4–40.2 g kg1. No CTC and DOX residues were found in all the samples analyzed. Liver samples showed the highest average values (31.5 20.6 and 21.8 18.9 for OTC and TC, respectively). The results showed a low incidence of TCs in all the samples examined, in comparison with other studies reported in the literature. A significant decrease in TC residues frequency was found from 2013 (p < 0.05). This work reports for the first time epidemiological data on the presence of TC residues in liver and muscle samples of cattle farmed in Sicily (Southern Italy). The very low incidence of TC residues indicates a continuous improvement in farming techniques in Southern Italy, which is essential to ensure consumers’ protection
