Is there an in-group advantage in emotion recognition?

H. A. Elfenbein and N. Ambady (2002) examined the evidence for an in-group advantage in emotion recognition, whereby recognition is generally more accurate for perceivers from the same cultural group as emotional expressors. D. Matsumoto's (2002) comment centered on 3 asserted methodological requirements. This response addresses the lack of consensus conceming these "requirements" and demonstrates that none alter the presence of the in-group advantage. His analyses had a serious flaw and, once corrected, replicated the original findings. Furthermore, he described results from his empirical work not meeting a literal interpretation of his own requirements. Overall, where Matsumoto considers subtle cross-cultural differences in emotional expression a methodological artifact in judgment studies, the present authors find a core phenomenon worthy of attention.     

Is there an evolutionary advantage of schizophrenia?

Schizophrenia is a universal disorder with strongly genetic aetiology. A constant prevalence rate, universally, in the face of reduced fecundity leads to the argument here that an evolutionary advantage exists, but not solely for schizophrenia. Possible areas of advantage are examined and it is argued that schizophrenia exists as a costly trade-off, in the evolution of Homo sapiens, as a by-product of a yet unknown uniquely human quality. The reason it has stayed in existence is due to a combination of advantages bestowed upon the kin, the group and, to a lesser extent, individuals who suffer from the disorder; these all contribute a different type of advantage, each of which alone would not be sufficient. Further, the evidence for the other advantages alone lack the rigour of evidence seen in the by-product theories, which provide as yet unparalleled comprehensive evolutionary evidence.     

Spatial patterns in tactile perception: is there a tactile field?

Previous studies of tactile spatial perception focussed either on a single point of stimulation, on local patterns within a single skin region such as the fingertip, on tactile motion, or on active touch. It remains unclear whether we should speak of a tactile field, analogous to the visual field, and supporting spatial relations between stimulus locations. Here we investigate this question by studying perception of large-scale tactile spatial patterns on the hand, arm and back. Experiment 1 investigated the relation between perception of tactile patterns and the identification of subsets of those patterns. The results suggest that perception of tactile spatial patterns is based on representing the spatial relations between locations of individual stimuli. Experiment 2 investigated the spatial and temporal organising principles underlying these relations. Experiment 3 showed that tactile pattern perception makes reference to structural representations of the body, such as body parts separated by joints. Experiment 4 found that precision of pattern perception is poorer for tactile patterns that extend across the midline, compared to unilateral patterns. Overall, the results suggest that the human sense of touch involves a tactile field, analogous to the visual field. The tactile field supports computation of spatial relations between individual stimulus locations, and thus underlies tactile pattern perception.     

Is there a chaplain in your clinic?

As medical care continues to move outside the hospitals, clients with spiritual needs are more often to be found in clinics and doctors' offices than inpatient settings. Chaplains in partnership with physicians can contribute to healing in outpatient centers. A study of one group of clinic patients indicates that an outpatient setting may be a better place to address spiritual needs than a hospital setting. Pastoral interventions are acceptable to many clients, who according to statistics are already using alternative therapies to augment traditional medical care. Paul A. Mandziuk, M. Div., a priest of the Missionaries of La Salette, is a chaplain at Saint Louis University Health Sciences Center in St. Louis, MO, and serves on the leadership council of the National Association of Catholic Chaplains.     

Is there a religious factor in health?

This paper reviews epidemiologic studies employing religion as an independent construct, and finds that most epidemiologists have an extremely limited appreciation of religion. After a historical overview of empirical religion and health research, some theoretical considerations are offered, followed by clarification of several operational and methodological issues. Next, well over 200 studies are reviewed from nine health-related areas: cardiovascular disease, hypertension and stroke, colitis and enteritis, general health status, general mortality, cancer of the uterine corpus and cervix, all other non-uterine cancers, morbidity and mortality in the clergy, and cancer in India. Finally, an agenda for further research is proposed.     

Is there a magnitude effect in tipping?

The present study examined nearly 1,000 tips recorded for two taxicabs, two hair salons, and two restaurants. In each of the six cases, amount of tip increased linearly as a function of the amount of the bill. Contrary to standard microeconomic theory, there was a magnitude effect in that as the amount of the bill increased, the percent tip tended to decrease. The present results extend the findings of Chapman and Winquist (1998), obtained using hypothetical scenarios, to real-world tipping behavior. Chapman and Winquist argued that a magnitude effect in tipping reflects the shape of the utility function for money. We suggest, however, that the magnitude effect may be the mathematical consequence of replotting the fundamental relationship between tip and bill amounts in terms of percent tip, given that the observed linear relation between tip and bill amounts has a positive intercept. We suggest further that the positive intercept arises because a tip represents a judgment as to what constitutes a fair or equitable wage, and part of what constitutes a fair wage is independent of the amount of the bill, reflecting compensation for simply being there when needed. The present account implies that different explanations may be needed for magnitude effects observed in different domains.     

Is there an epistemic advantage to being oppressed?

Do the oppressed have an epistemic advantage when it comes to knowing about the systems that oppress them? If so, what explains this advantage? In this paper, I consider whether an epistemic advantage can be derived from the oppressed's contingent tendency to have more relevant experiences and motivation than the non-oppressed; or, alternatively, whether an advantage derives from the oppressed's very lived experience, thus being in principle unavailable to the non-oppressed. I then explore the potential role of knowledge-how for explaining an epistemic advantage. Ultimately, I conclude that the oppressed tend to have a contingent advantage, while rejecting that they have one in principle, except for when their phenomenological experience has an effect on the veracity of the claims they make. This has the important upshot that privileged people are not epistemically disadvantaged in principle and are thus often blameworthy for their ignorance about oppression.     

Spatial organisation in passive tactile perception: is there a tactile field?

The perceptual field is a cardinal concept of sensory psychology. 'Field' refers to a representation in which perceptual contents have spatial properties and relations which derive from the spatial properties and relations of corresponding stimuli. It is a matter of debate whether a perceptual field exists in touch analogous to the visual field. To study this issue, we investigated whether tactile stimuli on the palm can be perceived as complex stimulus patterns, according to basic spatial principles. Subjects judged the intensity of a target stimulus to the palm, ignoring two brief preceding touches at nearby flanker locations. We found that the judgements of the target intensity were boosted by flankers when the target lay on the line joining the flankers in comparison to when the target lay away from this line. Therefore, we suggest that a tactile spatial organisation, i.e. a tactile field, exists; the field supports the relation of collinearity; it is automatically and implicitly activated by touch, and it groups spatially coherent perceptual contents.     

Is there a search in fixed-set memory search?

We discuss the hypothesis that structural factors in the fixed-set memory-search task may contribute to the standard linear set-size effect typically observed in this task. We constructed a lexical decision task that contained the same structural factors as the memory-search task. Two structural factors are discussed: (1) the priming of the probe by the memory set, and (2) the confounding of repetitions per item with set size. Our experiment demonstrated that these structural factors play a role in the set-size effect. The implications of these effects for the memory-search task and for models proposed to account for memory-search data are discussed.     

Is there a duty to remain in ignorance?

Questions about information inform many debates in bioethics. One of the reasons for this is that at least some level of information is taken by many to be a prerequisite of valid consent. For others, autonomy in the widest sense presupposes information, because one cannot be in control of one’s life without at least some insight into what it could turn out to contain. Yet not everyone shares this view, and there is a debate about whether or not there is a right to remain in ignorance of one’s medical, and especially genetic, information. It is notable, though, that this debate leaves unexamined the assumption that, if a person wants information, he is entitled to it. This paper examines the assumption, specifically in relation to genetics, where learning facts about oneself may reveal facts about other people, particularly one’s close relatives. This may be taken as a violation of their privacy, and since privacy is something that we normally think should be respected, it is worth asking whether one ought to abjure the opportunity to obtain genetic information for the sake of privacy. In effect, there may be an argument to be made not just for a right to remain in ignorance, but for a duty to do so.     

Is there an advantage for recognizing multi-modal emotional stimuli?

Emotions can be recognized whether conveyed by facial expressions, linguistic cues (semantics), or prosody (voice tone). However, few studies have empirically documented the extent to which multi-modal emotion perception differs from uni-modal emotion perception. Here, we tested whether emotion recognition is more accurate for multi-modal stimuli by presenting stimuli with different combinations of facial, semantic, and prosodic cues. Participants judged the emotion conveyed by short utterances in six channel conditions. Results indicated that emotion recognition is significantly better in response to multi-modal versus uni-modal stimuli. When stimuli contained only one emotional channel, recognition tended to be higher in the visual modality (i.e., facial expressions, semantic information conveyed by text) than in the auditory modality (prosody), although this pattern was not uniform across emotion categories. The advantage for multi-modal recognition may reflect the automatic integration of congruent emotional information across channels which enhances the accessibility of emotion-related knowledge in memory.     

Working memory in multilingual children: Is there a bilingual effect?

This research investigates whether early childhood bilingualism affects working memory performance in 6- to 8-year-olds, followed over a longitudinal period of 3 years. The study tests the hypothesis that bilinguals might exhibit more efficient working memory abilities than monolinguals, potentially via the opportunity a bilingual environment provides to train cognitive control by combating interference and intrusions from the non-target language. A total of 44 bilingual and monolingual children, matched on age, sex, and socioeconomic status, completed assessments of working memory (simple span and complex span tasks), fluid intelligence, and language (vocabulary and syntax). The data showed that the monolinguals performed significantly better on the language measures across the years, whereas no language group effect emerged on the working memory and fluid intelligence tasks after verbal abilities were considered. The study suggests that the need to manage several language systems in the bilingual mind has an impact on children's language skills while having little effects on the development of working memory.     

Is there a place for Feminists in a Christian Church?

Based on a dialogue held on 16 May 1986 in London at Westminster Cathedral Hall, and organised by Catholic Women's Network and Women in Theology. Dr Daphne Hampson presents her own position at length, Dr Rosemary Ruether responds to it at length, and a discussion between the two of them follows.     

Is there a primordial Torah?

Is Orthodox Judaism committed to the existence of a Torah that pre-existed the world? This paper argues that Orthodoxy is so committed unless it can find compelling philosophical or theological reasons to reject the possibility of such an entity, and then to re-interpret allegorically all of the texts that speak of such a Torah. Providing an ontology of primordial texts, I argue that no compelling reason can be found to deny the existence of the primordial Torah.     

Is there a neutral metalanguage?

Logical pluralists are committed to the idea of a neutral metalanguage, which serves as a framework for debates in logic. Two versions of this neutrality can be found in the literature: an agreed upon collection of inferences, and a metalanguage that is neutral as such. I discuss both versions and show that they are not immune to Quinean criticism, which builds on the notion of meaning. In particular, I show that (i) the first version of neutrality is sub-optimal, and hard to reconcile with the theories of meaning for logical constants, and (ii) the second version collapses mathematically, if rival logics, as object languages, are treated with charity in the metalanguage. I substantiate (ii) by proving a collapse theorem that generalizes familiar results. Thus, the existence of a neutral metalanguage cannot be taken for granted, and meaning-invariant logical pluralism might turn out to be dubious.

     

Is there a role for psychology in ulcer disease?

The discovery of the importance of bacterial factors in the etiology of ulcer disease has led to a neglect of psychological factors. However, both earlier theoretical and empirical approaches implicating these factors are supported by more recent studies, both epidemiological and experimental. While not ignoring the unquestioned role of Helicobacter, it is important for future research to recognize the multi-factorial nature of ulcer disease by which several factors, including stress, bacteria and non-steroid anti-inflammatory drugs, may interact to drive a pre-pathology (erosions or ulcerations) to a pathological state (ulcer). Calls for general eradication programs should be cautioned in the light of possible unwanted side effects.
