What bats have to say about speech and language

Understanding the biological foundations of language is vital to gaining insight into how the capacity for language may have evolved in humans. Animal models can be exploited to learn about the biological underpinnings of shared human traits, and although no other animals display speech or language, a range of behaviors found throughout the animal kingdom are relevant to speech and spoken language. To date, such investigations have been dominated by studies of our closest primate relatives searching for shared traits, or more distantly related species that are sophisticated vocal communicators, like songbirds. Herein I make the case for turning our attention to the Chiropterans, to shed new light on the biological encoding and evolution of human language-relevant traits. Bats employ complex vocalizations to facilitate navigation as well as social interactions, and are exquisitely tuned to acoustic information. Furthermore, bats display behaviors such as vocal learning and vocal turn-taking that are directly pertinent for human spoken language. Emerging technologies are now allowing the study of bat vocal communication, from the behavioral to the neurobiological and molecular level. Although it is clear that no single animal model can reflect the complexity of human language, by comparing such findings across diverse species we can identify the shared biological mechanisms likely to have influenced the evolution of human language.     

What fair procedures say about me: Self-construals and reactions to procedural fairness

Past research has revealed both positive and negative reactions when people receive unfavorable outcomes via fair decision-making procedures. In three laboratory experiments, we reconcile these findings by considering the role of people’s self-identity. Our results suggest that the more that people base their self-identity on their relationships with others—as indexed by a strong interdependent self-construal—the more positively they react to an unfavorable outcome following from fair procedures. Conversely, the more that people base their self-identity on achievement—as indexed by a strong independent self-construal—the more negatively they react to an unfavorable outcome following from fair procedures. Moreover, these results were stronger when the situation primed interdependence and independence, respectively. Our research indicates that people interpret procedural fairness information in a manner that is consistent with defining aspects of the self.     

Psycho-logic: some thoughts and after-thoughts

The main features of the system of psycho-logic and its historical origins, especially in the writings of Heider and Piaget, are briefly reviewed. An updated version of the axioms of psycho-logic, and a list of the semantic primitives of Wierzbicka are presented. Some foundational questions are discussed, including the genetically determined limitations of human knowledge, the constructive, moral, and political nature of the approach, the role of fortuitous events, the ultimate limitations of psychological knowledge (the "balloon" to be inflated from the inside), the role of the subjective unconscious, and the implications of the approach for practice.     

What you say and how you say it: the contribution of speech content and voice quality to judgments of others

In three studies, judgments based on separated channels (speech content, voice quality, face alone and body alone) were correlated with judgments based on combined channels (speech, face + speech, and face + body + speech). The judges observed spontaneous behavior in two different types of interview situations and rated various aspects of the behavior. Correlations between separated and combined channels varied significantly depending on the kind of behavior judged, the attribute rated, and whether other channels of information were available.     

What to say to a skeptical metaphysician: a defense manual for cognitive and behavioral scientists

A wave of recent work in metaphysics seeks to undermine the anti-reductionist, functionalist consensus of the past few decades in cognitive science and philosophy of mind. That consensus apparently legitimated a focus on what systems do, without necessarily and always requiring attention to the details of how systems are constituted. The new metaphysical challenge contends that many states and processes referred to by functionalist cognitive scientists are epiphenomenal. It further contends that the problem lies in functionalism itself, and that, to save the causal significance of mind, it is necessary to re-embrace reductionism. We argue that the prescribed return to reductionism would be disastrous for the cognitive and behavioral sciences, requiring the dismantling of most existing achievements and placing intolerable restrictions on further work. However, this argument fails to answer the metaphysical challenge on its own terms. We meet that challenge by going on to argue that the new metaphysical skepticism about functionalist cognitive science depends on reifying two distinct notions of causality (one primarily scientific, the other metaphysical), then equivocating between them. When the different notions of causality are properly distinguished, it is clear that functionalism is in no serious philosophical trouble, and that we need not choose between reducing minds or finding them causally impotent. The metaphysical challenge to functionalism relies, in particular, on a na?ve and inaccurate conception of the practice of physics, and the relationship between physics and metaphysics.     

What is meant by telling the truth: Bonhoeffer on the ethics of disclosure

This article explores Dietrich Bonhoeffer's writings on truth telling with reference to the problem of medical error in the US, the UK, and other developed nations, with particular attention to physicians' resistance to disclosing their own mistakes to injured patients and their families. The brief essay 'What is Meant by "Telling the Truth"?' and its historical context--Bonhoeffer's imprisonment and interrogation in 1943--is proposed as a text for medical ethicists and others seeking to overcome the barrier of the 'hidden curriculum' within the culture of medicine, which encourages medical students and physicians to conceal their errors and to fear disclosure.     

What you say matters: exploring visual-verbal interactions in visual working memory

The aim of this study was to explore whether the content of a simple concurrent verbal load task determines the extent of its interference on memory for coloured shapes. The task consisted of remembering four visual items while repeating aloud a pair of words that varied in terms of imageability and relatedness to the task set. At test, a cue appeared that was either the colour or the shape of one of the previously seen objects, with participants required to select the object's other feature from a visual array. During encoding and retention, there were four verbal load conditions: (a) a related, shape-colour pair (from outside the experimental set, i.e., "pink square"); (b) a pair of unrelated but visually imageable, concrete, words (i.e., "big elephant"); (c) a pair of unrelated and abstract words (i.e., "critical event"); and (d) no verbal load. Results showed differential effects of these verbal load conditions. In particular, imageable words (concrete and related conditions) interfered to a greater degree than abstract words. Possible implications for how visual working memory interacts with verbal memory and long-term memory are discussed.     

Letting go: some thoughts about termination

Termination of analysis is discussed from three perspectives. First, considered as a vicissitude of the analytic relationship, termination contains essential elements of the psychoanalytic process itself. Cycles of attachment, loss, mourning, and internalization mark moments in, as well as overviews of, every analysis from its beginning to well past its termination. Second, Freud's approach to the subject of termination is explored and widened, with an emphasis on its relation to mourning and on the depth and permanence of analytic transference--two dimensions relatively neglected by Freud, perhaps for personal reasons. Finally, clinical issues are presented that are meaningful to the author in his work with analysands, including his work as a training analyst.     

You can say what you think: vindicating the effability of our thoughts

The thesis of Ineffability has it that no proposition can be fully expressed by a sentence, this meaning that no sentence-type, or even sentence-token whose indexicality and ambiguities have been resolved, can fully encode a proposition. The thesis of the propositionality of thoughts has it that thoughts are propositional. An implication of the joint endorsement of these two theses is that thoughts are ineffable. The aim of this paper is to argue that this is not the case: there are effable thoughts, and we can even safely say that, generally, thoughts are effable. In order to defend this insight, I first counter the thesis of the propositionality of thought by bringing some counterexamples to it, which amount to cases of non-fully propositional thought. I then argue that, if thoughts can be and often are non-fully propositional, they can be expressed by sentences that fail to fully express a proposition. I also show that the propositional thoughts that we can entertain are after all effable (in a suitable, relevant sense) and resist some alleged examples of insurmountable ineffability.     

What mothers don't know and doctors don't say: Detecting early developmental delays

The present study examined the detection of early developmental delays of high‐risk infants by first‐time mothers in a community sample of families (N = 451). About half of the mothers were adolescents at time of childbirth, and two thirds reported household incomes below $20,000 annually. Children were assessed at 12 and 24 months of age on standardized measures of cognitive, language, adaptive, and socioemotional development. According to the Individuals with Disabilities Education Act (PL101‐476) guidelines, about 1 in 4 children was eligible for intervention services at 12 months, and about 1 in 3 children was eligible at 24 months. Despite receiving regular medical services, mothers reported that very few eligible children (2% at 12 months and 9% at 24 months) were identified by medical professionals as having any problems that could interfere with development. Much like medical professionals, few mothers were appropriately worried about development, and the likelihood of expressing concerns was related to mothers' knowledge about infant development. These findings highlight the need for medical providers to frequently screen high‐risk children and for parents to become more knowledgeable about infant development.     

Healthy family functioning: What family therapists,priests, and ministers say

This study compared the concepts of healthy family functioning as perceived by family therapists, Roman Catholic priests, and Southern Baptist ministers. The therapists emphasized the importance of individuation and flexibility. In contrast, the ministers placed greater emphasis on family togetherness rather than individuation, and both the ministers and the priests placed greater emphasis on structure and authority rather than flexibility. The implication of these and other findings are discussed.     

Racial attitudes in response to thoughts of white privilege

Thinking about the benefits gained from a privileged group membership can threaten social identity and evoke justification of the existing status difference between the ingroup and a disadvantaged group. For White Americans, racial privilege may be justified by concurring with modern racist attitudes. In Experiment 1, White Americans randomly assigned to think about White privilege expressed greater modern racism compared to those assigned to think about White disadvantage or a race‐irrelevant topic. In Experiment 2, we found that increased racism in response to thoughts of White privilege was limited to those who highly identified with their racial category. In contrast, when White racial identification was sufficiently low, thoughts of White privilege reliably reduced modern racism. We discuss the implications of these findings for the meaning of modern racism and prejudice reduction. Copyright © 2006 John Wiley & Sons, Ltd.     

Why pigeons say what they do: reinforcer magnitude and response requirement effects on say responding in say-do correspondence

The effects of reinforcer magnitude and response requirement on pigeons' say choices in an experimental homologue of human say-do correspondence were assessed in two experiments. The procedure was similar to a conditional discrimination procedure except the pigeons chose both a sample stimulus (the say component) and a comparison stimulus that corresponded to it (the do component). Correspondence was trained on red, green, and white key colors before the duration of food presentations following correspondence on each key color (Experiment 1) and the number of key pecks required as the say response on each key color (Experiment 2) were manipulated in an attempt to influence the initial say response. The frequency of say responses on each key color coincided with programmed changes in the duration of food presentations and the key-peck requirements assigned to each key color. Correspondence accuracy remained stable in all conditions, even those in which the say responding occurred primarily on two of the three key colors. Implications for human behavior are discussed.     

Religion and the use of animals in research: some first thoughts

Religious traditions can be drawn on in a number of ways to illuminate discussions of the moral standing of animals and the ethical use of animals in scientific research. I begin with some general comments about relevant points in the history of major religions. I then briefly describe American civil religion, including the cult of health, and its relation to scientific research. Finally, I offer a critique of American civil religion from a Christian perspective.     

Conditioning decorticate canines in Culler's laboratory: some reflexions and second thoughts

Rapid expansion and increasing specialization, characteristics of the progress of science in general, occurred in physiological psychology in the 1930s. The development of E. A. K. Culler's laboratory at the University of Illinois may be representative of this phenomenon. Controversial problems raised during the writer's participation in the laboratory, such as conditioning in the decorticate and distribution and function of the cerebral auditory system, are considered from a present-day perspective. It is suggested that conceptual constraints imposed by some outstanding leaders, as illustrated with Pavlov, may no longer play the dominant role as described earlier in psychology's growth.
