The biological basis of the commonality in color lexicons across languages has been hotly debated for decades. Prior evidence that infants categorize color could provide support for the hypothesis that color categorization systems are not purely constructed by communication and culture. Here, we investigate the relationship between infants’ categorization of color and the commonality across color lexicons, and the potential biological origin of infant color categories. We systematically mapped infants’ categorical recognition memory for hue onto a stimulus array used previously to document the color lexicons of 110 nonindustrialized languages. Following familiarization to a given hue, infants’ response to a novel hue indicated that their recognition memory parses the hue continuum into red, yellow, green, blue, and purple categories. Infants’ categorical distinctions aligned with common distinctions in color lexicons and are organized around hues that are commonly central to lexical categories across languages. The boundaries between infants’ categorical distinctions also aligned, relative to the adaptation point, with the cardinal axes that describe the early stages of color representation in retinogeniculate pathways, indicating that infant color categorization may be partly organized by biological mechanisms of color vision. The findings suggest that color categorization in language and thought is partially biologically constrained and have implications for broader debate on how biology, culture, and communication interact in human cognition.

Defining synaesthesia has proven to be a challenging task as the number of synaesthesia variants and associated phenomena reported by synaesthetes has increased over the past decade or so. This chapter discusses the inclusion of non-sensory concurrents in the category of synaesthesia. For example, many grapheme-colour synaesthetes also attribute gender and personality to letters and numbers consistently and involuntarily. Here we assess the question of including synaesthetic personification as a type of synaesthesia. We also discuss the relationship between synaesthetic personification and other instances of personification and mentalizing. We hope to convince readers that whether or not they embrace atypical forms of personification as a synaesthesia variant, studying the phenomenon is a worthwhile effort that could yield novel insights into human cognition and brain function.

Abstract Study question Do couples undergoing assisted reproduction treatments (ART) have a different perception of anonymous vs identity-release gamete donation than a population interested in the subject? Summary answer Compared with a population interested in the subject, more couples undergoing ART believed the child shouldn’t be given information that would identify the gamete-donor. What is known already Recent research has investigated the psychological well-being of parents and children born through gamete donation, focusing on the possibility of having the donor’s identity revealed. Gamete donors have traditionally been anonymous to recipients and offspring; however, there is a global trend towards programs using donors that are identifiable to the resulting offspring at maturity. While some countries only allow the use of identity-release egg donation, others only allow anonymous-donation, and in some countries both types of donation are practiced. However, the attitudes concerning anonymous vs identity-release gamete donation, in a country where only anonymous donation is allowed, are still unknown. Study design, size, duration This cross-sectional study was performed from 01/Sep/2020 to 15/Dec/2020. For that, surveys through online-platforms were conducted, including either patients undergoing ART, (ART-group, n = 358) or those interested in the subject, who accessed the website of a university-affiliated IVF-center (interested-group, n = 122). Participants in the ART-group were invited via e-mail, with a cover-letter outlining the survey and a link to access it and participants in the interested-group accessed the questionnaire via website. Participants/materials, setting, methods The survey collected information on demographic characteristics and the participant’s attitudes towards anonymity of gamete donors. The questions were: (i) In the case of children conceived through ART, do you believe that revealing the method of conception may affect the relationship between children and their parents? (ii) Once the method of conception is revealed, do you believe that the child has the right to know the gamete donor? (iii) If yes, when? Main results and the role of chance Most of the participants answered that the relationship between children and parents wouldn’t be affected by the child’s knowledge of the origin of their conception, regardless of the group (83.6% vs 82.7%, for ART-group and interested-group, respectively, p = 0.868). Most participants in the ART-group answered that the sperm donor identity shouldn’t be revealed to the child, while only half of the interested-group stated the same (65.4% vs 50.8%, p = 0.044). The same result was observed when participants were asked if the oocyte donor should be identifiable (64.8% vs 50.8%, p = 0.050). When asked when the donor’s identity should be revealed to the child, no significant differences were noted in the responses among the groups (p = 0.868). Most of the participants who believe that the child has the right of learning the donor’s identity, stated that “the donor’s identity should be revealed if the child questions its biological origin” (67.2% vs 67.5%, for ART-group and interested-group, respectively). “Since birth” was the second most common response, (21.0% vs 19.7%, for ART-group and interested-group, respectively), while “when the child turns 18 years-old” (9.2% vs 11.2%, for ART-group and interested-group, respectively), and “sometime during teenage years” (2.5% vs 2.4%, for ART-group and interested-group, respectively) were less common answers. Limitations, reasons for caution Lack of adequate opportunities to conduct face to face interview and lack of knowledge of the real state of the website participants, concerning infertility or being involved in ART. The retrospective nature of the study and the small sample size may also be reasons for caution, Wider implications of the findings: It has been discussed that, whether or not children or parents are harmed by knowing their biological origins, donor offspring have the right to know. However, when facing the situation, couples undergoing ART would argue that in case of gamete donation, there are reasons for not telling the child. Trial registration number Not applicable

This article presents some considerations into metaphor in language and thought- 'the topic and title of the first conference of its kind in Brazil'. The paper focuses on the discussions presented in the round table, which were mostly directed to the empirical research on metaphor in Applied Linguistics. This integrative and retrospective reflection on the papers presented will be conducted from the perspective of the debate into the relationship between metaphor in language and in thought. This central issue is at the core of my proposal for four different approaches to metaphor, based on the interdependence between language and thought as system and as use:1) metaphor in language as system; 2) metaphor in thought as system; 3) metaphor in language as use and 4) metaphor in thought as use. It is within the framework of these categories that metaphors should be studied, with a certain degree of autonomy, so that their interdependence can be better understood.

Individual animals behave differently from each other. This variability is a component of personality and arises even when genetics and environment are held constant. Discovering the biological mechanisms underlying behavioral variability depends on efficiently measuring individual behavioral bias, a requirement that is facilitated by automated, high-throughput experiments. We compiled a large data set of individual locomotor behavior measures, acquired from over 183,000 fruit flies walking in Y-shaped mazes. With this data set we first conducted a "computational ethology natural history" study to quantify the distribution of individual behavioral biases with unprecedented precision and examine correlations between behavioral measures with high power. We discovered a slight, but highly significant, left-bias in spontaneous locomotor decision-making. We then used the data to evaluate standing hypotheses about biological mechanisms affecting behavioral variability, specifically: the neuromodulator serotonin and its precursor transporter, heterogametic sex, and temperature. We found a variety of significant effects associated with each of these mechanisms that were behavior-dependent. This indicates that the relationship between biological mechanisms and behavioral variability may be highly context dependent. Going forward, automation of behavioral experiments will likely be essential in teasing out the complex causality of individuality.

The relationship between the civilisation illnesses and incorrect nutrition can be considered as demonstrated. The functional foods having one or several nutritional- biological advantage can contribute to the healthy nutrition and to improving the quality of life. Beside the healthy nutrition it is an another important requirement that the food does not contain pathogens or substances of chemical and biological origin namely it has to be safe. In this publication the foods of animal origin were investigated in the point of view of public health hazards arising during their production and processing.The contamination and infection of food raw materials, the consequence of chemical substances getting in or developing it the food, the judgement of food deviring from genetically modified or cloned animals are discussed.

This chapter looks at Hans Blumenberg's “Speech Situation and Immanent Poetics” (1966), which focuses on poetic language. The three basic ideas of the relationship between language and thought should help one gain a certain orientation to determine the function of poetic language. After all, an immanent poetics will by necessity depend on examining the function of a work's language. The explication of the immanent poetics of a work will therefore depend on asking the “right” questions with regard to this work's language. Of course, hints can be derived from the author's exogenous poetics, from his self-testimony and self-observation, if this is indeed what they are and not simply the “offshoot” of a normative theory of art. This methodical preliminary question deserves not to be passed over. Already the classification of a text by its author as “self-observation” during the process of aesthetic production expresses a certain aesthetic position. This position permits experience to provide relevant information about the process of a work's emergence.

In 1929 Hans Berger discovered the alpha oscillations: prominent, ongoing oscillations around 10 Hz in the electroencephalogram of the human brain. These alpha oscillations are among the most widely studied brain signals, related to cognitive phenomena such as attention, memory and consciousness. However, the mechanisms by which alpha oscillations affect human cognition await demonstration. Here, we suggest the honey bee brain as an experimentally more accessible model system for investigating the functional role of alpha oscillations. We found a prominent spontaneous oscillation around 18 Hz that is reduced in amplitude upon olfactory stimulation. Similar to alpha oscillations in primates, the phase of this oscillation biased both timing of neuronal spikes and amplitude of high-frequency gamma activity (40–450 Hz). These results suggest a common role of alpha oscillations across phyla and provide an unprecedented new venue for causal studies on the relationship between neuronal spikes, brain oscillations and cognition.
