Relations between emotion, memory, and attention: evidence from taboo stroop, lexical decision, and immediate memory tasks.

This article reports five experiments demonstrating theoretically coherent effects of emotion on memory and attention. Experiments 1-3 demonstrated three taboo Stroop effects that occur when people name the color of taboo words. One effect is longer color-naming times for taboo than for neutral words, an effect that diminishes with word repetition. The second effect is superior recall of taboo words in surprise memory tests following color naming. The third effect is better recognition memory for colors consistently associated with taboo words rather than with neutral words. None of these effects was due to retrieval factors, attentional disengagement processes, response inhibition, or strategic attention shifts. Experiments 4 and 5 demonstrated that taboo words impair immediate recall of the preceding and succeeding words in rapidly presented lists but do not impair lexical decision times. We argue that taboo words trigger specific emotional reactions that facilitate the binding of taboo word meaning to salient contextual aspects, such as occurrence in a task and font color in taboo Stroop tasks.

In vitro reactivity of allospecific cytotoxic T lymphocytes does not explain the taboo phenomenon.

Matching for human leucocyte antigens (HLA) is important for graft survival in kidney transplantation. Nevertheless, most patients receive a kidney graft with multiple HLA mismatches. Some of these mismatches seem to be more harmful than others. By studying the effect of single HLA mismatches in the context of the patients' own HLA, we have previously identified donor/recipient combinations with a significantly higher incidence of early graft failure, the so-called taboo combinations. In the present study we investigated whether a higher cytotoxic T lymphocyte (CTL) response towards taboo mismatches may be involved in this phenomenon. CTL reactivity was determined both in taboo and control combinations by in vitro CTL precursor assays, using peripheral blood mononuclear cells and proximal tubular epithelial cells as target cells. Inhibition studies with CD8-antibody as well as Cyclosporin A were performed to identify high avidity and primed CTLs. Furthermore, in committed CTLp assays indirect recognition of the taboo mismatch was tested using synthetic peptides. The CTL precursor frequencies in taboo combinations were always lower than the CTL precursor frequencies in control combinations. No difference in avidity and activation status of the CTLs could be detected when taboo combinations were compared with the controls. In the committed CTLp assays no reactivity towards any of the synthetic peptides was observed. The significantly poorer graft survival of taboo combinations cannot be explained by a higher number of donor-specific CTLs. Furthermore, the avidity or activation status of these CTLs does not provide a clue to the taboo phenomenon.

Freud's presentation of 'the psychoanalytic mode of thought' in Totem and taboo and his technical papers.

Freud considered 'the psychoanalytic mode of thought' to be an instrument of research. In 'Totem and Taboo', he demonstrated his mode of thinking by applying it to the data of contemporary studies of totemism. While taking the reader along the paths of his selection and weighing of information, he also applied clinical discoveries about mental life in reconstructing 'primitive psychological situations' in the distant past. In the technical papers that appeared concurrently with his book, he applied to the clinical situation the ideas on transference, narcissism, primitive mental mechanisms and unconscious communication that he had explored in 'Totem and Taboo'. In this paper, the author presents material showing the structure of Freud's exposition as a model of analytic exploration. Some of the principles of mental organisation mentioned by Freud are discussed. Examples are given of the close parallels between 'Totem and Taboo' and two technical papers. The author suggests that 'Totem and Taboo' is an important step in Freud's development of his theory of object relations and his ideas about the intersubjectivity of unconscious mental life.

Emotion, memory, and attention in the taboo Stroop paradigm.

This study tested the binding hypothesis: that emotional reactions trigger binding mechanisms that link an emotional event to salient contextual features such as event location, a frequently recalled aspect of naturally occurring flash-bulb memories. Our emotional events were taboo words in a Stroop color-naming task, and event location was manipulated by presenting the words in different task-irrelevant screen locations. Seventy-two participants named the font color of taboo and neutral words, with instructions to ignore word meaning; in one condition, several words were location consistent (i.e., always occupied the same screen location), whereas in another condition, several colors were location consistent. Then, in a surprise recognition memory test, participants recalled the locations of location-consistent words or colors. Although attention enhanced overall location memory for colors (the attended dimension during color naming), emotion (taboo vs. neutral words) enhanced location memory for words but not colors. These results support the binding hypothesis but contradict the hypothesis that emotional events induce image-like memories more often than non-emotional events.

Palliative care and taboos within motor neurone disease.

Taboos, whether held by professional carers, patients or families have the capacity to influence a whole range of choices that must be made during the course of any illness. In the case of motor neurone disease, decisions regarding if, when and how to break bad news, the place of care (home, hospital or hospice), the introduction of aids and devices, and, ultimately, choices regarding the place of death, will all be influenced by a range of taboos. If professional carers have major unresolved issues concerning their own mortality, it is unlikely that they will be able to truly stand alongside those who are facing their own imminent death. In discussing taboos, essentially what is of concern is attitudes. A basic change in attitudes is required if we are to stop viewing patients with incurable illness as some kind of medical failure.

[Food taboos in the northern region of Brazil].

A study was carried out into alimentary taboos in two localities (São Félix and Murumuru) in the county of Marabá, State of Pará, Brazil. Ninety families were studied in São Félix and thirty-five in Murumuru. As regards the feeding taboos found, the most frequent was that prohibiting the simultaneous ingestion of milk and various types of fruit, including especially mango, orange, cashew and pineapple. The ingestion of eggs with fruit was also considered harmful as well as the eating of mammalian flesh at the same time as fish. Restrictions based on taboos were more frequent during breast feeding than during pregnancy, especially those regarding game flesh and fish that abound in the region under study. The most frequently mentioned reasons for the restrictions were: "the combination causes harm", "the combination kills", "the combination causes congestion" and "it causes vomiting".

Effects of taboo words on color-naming performance on a stroop test.

The effect of irrelevant taboo and control words on performance on the Stroop task was examined. The mean response time for taboo words was higher than that for control words. Single stimulus presentation made it possible to estimate internal consistency for interference of taboo words, which was acceptable (Cronbach alpha = .80).

Food taboos among nursing mothers of Mexico.

This cross-sectional study was carried out in Guadalajara, Mexico, during 1998-1999 to identify food taboos among nursing mothers who participated in a breast-feeding support programme. The study included 493 nursing mothers who were interviewed 10-45 days after delivery. A chi-square test was used for finding an association among food taboos, mother's characteristics, and demographic variables. 50.3% of the mothers avoided at least one food in their diet after childbirth due to beliefs that it was harmful during breast-feeding. Forty-seven percent avoided three or more foods. Fruits and vegetables (62%) and legumes (20%) were the most-avoided foods. These food taboos were associated with living more than 10 years in Guadalajara city (odds ratio [OR] 1.95 [1.25-3.09], p = 0.002), breast-feeding experience (OR 1.91 [1.18-3.12], p = 0.005), no-prenatal information about breast-feeding (OR 1.59 [1.08-2.34], (p = 0.01), and other people's suggestion to complement breast-feeding (OR 1.61 [1.09-2.38], p = 0.01). A supportive approach and efficient communication, taking into account mother's characteristics, might reduce the gap between scientific recommendations and nutritional practices of mothers willing to nurse their infants.

Incestuous gene in consanguinophilia and incest: toward a consilience theory of incest taboo.

Westermarck's theory of incest taboo states that inhibition of sexual attraction between biologically close relatives is situational and develops during co-residence in early childhood. By contrast, the biological (genetic) basis of incest taboo is presumed from its universality in all human societies and animals and teleologically, from the need to prevent the detrimental effects of inbreeding. As incest taboo violation is infrequent, the frequency of the presumed gene in the population is believed to be near 100%. We present arguments which suggest that the incestuous gene may exist in all populations and could play an important role in evolution. When malaria emerged 10,000 years ago, human adaptation proceeded by the selection of protective genotypes. Among them, homozygotes for alpha-thalassemia, hemoglobin C, and Duffy antigen negative blood group, have better survival odds in malarious regions than heterozygotes and those with normal genotypes. Since consanguinity increases homozygosity, it increases the number of persons who are resistant to malaria. To pro-create, however, biologically close individuals must not feel sexual aversion that normally develops between those who spend their early childhood together (Westermarck effect). It is reasonable to assume, therefore, that mutation of the gene that discourages inbreeding may have appeared at an early time in evolution, and produced a weak Westermarck effect. This gene (we will call it anti-w) failed to inhibit mating between kins. Inbred offspring of anti-w carriers, would statistically, more likely carry both anti-w and homozygote genotypes which increase fitness in the presence of malaria. Today, alpha-thalassemia is the single most common monogenetic disorders in man with over 500 millions carriers concentrated in malarious regions of the world. The world's consanguineous population is some 500-800 millions and is also concentrated in malarious regions. Population migration has spread the gene outside areas of high malaria endemicity. However, endemicity of malaria provides a worldwide gradient of genotype frequencies which makes the incestuous gene hypothesis testable. We propose that the incestuous anti-w allele was co-selected with some of the genes protective against malaria because anti-w facilitates mating between genetically close individuals whose offspring better survive malaria.

Association between specific HLA combinations and probability of kidney allograft loss: the taboo concept.

BACKGROUND: HLA matching improves the outcome of cadaveric renal transplantation. However, many allografts function well even in the presence of one or more HLA mismatches, which raises the question of whether some mismatches are better recognised by the recipient's immune system than others. We aimed to identify mismatched HLA donor-recipient combinations that were associated with increased graft loss. METHODS: We selected 2877 first, unrelated renal transplants with a single HLA A, B, or DR mismatch, undertaken between 1982 and 1992, from the Eurotransplant database. To enhance statistical power the analysis was restricted to mismatches of an HLA antigen that occurred in 100 or more donors. 1342 transplants met this criterion and were grouped into a definition set (n = 873) and a validation set (n = 469). In the definition set, we studied further only those recipient HLA antigens that occurred in at least 30 cases within each donor antigen mismatch subset. By a Cox proportional hazards model, donor-recipient combinations that led to significantly higher graft loss than in the whole group were defined. Such combinations were classified as taboo; the remaining combinations were classified as indifferent. FINDINGS: 106 individual recipient antigens were found at least 30 times with a corresponding donor mismatch in the definition set; 11 of the 106 had a significant effect on graft survival. Seven combinations were classified as taboo. Taboo combinations, confirmed as such in the validation set, were associated with graft survival of 81% at one year and 50% at 5 years, significantly lower than the rates in the group with indifferent combinations (89% and 69%; p = 0.04) or among 1190 recipients with no mismatches (89% and 72%; p = 0.03). The findings were substantiated by a multivariate analysis that included the effect of patient immunisation, cold ischaemia time, age, and sex. INTERPRETATION: Mismatched donor antigens are differentially recognised depending on the HLA phenotype of the recipient. The findings may have important clinical consequences for graft survival after transplantation.

Thinking the unthinkable: sacred values and taboo cognitions.

Many people insist that their commitments to certain values (e.g. love, honor, justice) are absolute and inviolable - in effect, sacred. They treat the mere thought of trading off sacred values against secular ones (such as money) as transparently outrageous - in effect, taboo. Economists insist, however, that in a world of scarce resources, taboo trade-offs are unavoidable. Research shows that, although people do respond with moral outrage to taboo trade-offs, they often acquiesce when secular violations of sacred values are rhetorically reframed as routine or tragic trade-offs. The results reveal the peculiar character of moral boundaries on what is thinkable, alternately punitively rigid and forgivingly flexible.

Food taboos in maternal and child health: the views of traditional healers in Ile-Ife, Nigeria.

This paper reports the interviews with 82 randomly selected healers in Ile-Ife about food taboos in relation to maternal and child health. The healers were asked to list the childhood ailments they treat most often and the food proscriptions and prescriptions associated with these ailments. Of particular interest in the study was the fact that these food proscriptions and prescriptions form an integral part of traditional medical procedures in that relapses or slow rate of recovery are sometimes attributed to a break of these food norms. Moreover, these proscriptions and prescriptions reflect: (i) the healers' concept of the various childhood diseases and (ii) the healers' belief in the respect for the traditional Yoruba gods in health matters. It was further noted that although these taboos reinforce the beliefs in traditional medicine, their relevance from the point of view of the health of the clientele needs further investigation.

The blood transfusion taboo of Jehovah's Witnesses: origin, development and function of a controversial doctrine.

Jehovah's Witnesses are not allowed to accept a blood transfusion. According to the Watch Tower Bible and Tract Society this therapy is a transgression of divine precepts. Additionally, in the judgement of the believers, secular proof is abundant these days; to them AIDS is a powerful justification to abstain from blood. Founded on the work of the anthropologist Mary Douglas, it is argued that the rejection of this medical therapy is based on perceptions of pollution and purity inherent in the Watch Tower Society's ideological concept of anti-worldliness. Rooted in the movement's pre-war opposition to vaccination the implementation of the taboo was triggered by the prevailing social-political climate surrounding the Society during the Second World War, resulting in this intriguing and controversial religious proscription. For the community of Jehovah's Witnesses the blood transfusion taboo still functions as a significant mechanism of sectarian boundary maintenance.

The incest taboo and family structure.

The evolutionary advantage of outbreeding has influenced the family structure and the mating, attachment, and dominance behaviors of all animals. Nature has selected for those species that have evolved family structures with detachment and dominance patterns that create a relatively intact incest barrier. Man inherits from his animal forebears the biological imperative of an incest barrier but brings to it his special complexity of psychology and symbolization--incest barrier becomes incest taboo. We present a discussion of human patterns of speparation-individuation and Oedipal conflict and relate this to the detachment and dominance behaviors of animals. This is an interface between psychoanalysis, family theory, and ethology. In addition, we pursue in detail the asymmetrical operation of the incest taboo within the family: that it is stronger for mother-son than for father-daughter than for brother-sister.

[Transference, taboo and truth].

The author re-examines the development of the concept of transference in Freud's work. He gives special attention to Totem and Taboo published in 1912-13. He notes that Freud's totally unsupported hypotheses within this model become illuminating and intelligible if "totem" is translated as "psychoanalyst" and "taboo" as "transference (neurosis)".

Study of food habits, food practices and taboos in Bangladesh: their implications in nutrition education.

The paper reports the findings of a retrospective study conducted to determine the prevailing food habits, food taboos and practices among 381 mothers selected randomly from twelve villages situated in 4 administrative divisions of Bangladesh. Undesirable food taboos and practices, maldistribution of food, lack of understanding of the nutritional needs of the vulnerable groups and bad cooking practices were found to be widespread in rural Bangladesh. Nutritional and health implications of these are discussed and remedial measures suggested.

[Review of theories on the foundations of the incest taboo].

Mainly because of its universality the incest taboo has been a field of investigation open to a number of disciplines. The author reviews the most important theories concerning the bases of this taboo, arranged according to the point of view, finalist or determinist. He then considers the anew in the light of recent acquisitions stemming from ethology and family theory. It has been demonstrated that an instinctive barrier against incest exists in the family life of wild animals, bringing into play defence mechanisms analogous to those that obtain in the human family. Developing the subject, the author shows on the one hand how this discovery calls in question certain postulates hitherto regarded as definitive, and on the other hand how it opens the way to a more synthetic view of the problem.

[Today's taboos--tomorrow's problems].

Societies need common taboos for their self-preservation. They can be regarded as social defence mechanisms and are therefore unconscious or dissociation phenomena. These qualities may explain many social incompatibilities and, as well as this, the inability of societies to introduce rationally-founded social changes. From this perspective, the decline of ethnic entities can be understood. Marking taboos may therefore be seen as a key to understanding social processes and social standstills. Here the present political developments in Germany serve as an example.
