Soltis/Signal Functions of Early Infant Crying: BBS Call for Commentators

Below is a link to the forthcoming BBS target article The Signal Functions of Early Infant Crying by Joseph Soltis http://www.bbsonline.org/Preprints/Soltis-11072002/Referees/ This article has been accepted for publication in Behavioral and Brain Sciences (BBS), an international, interdisciplinary journal providing Open Peer Commentary on important and controversial current research in the biobehavioral and cognitive sciences. Commentators must be BBS Associates or suggested by a BBS Associate. To be considered as a commentator for this article, to suggest other appropriate commentators, or for information about how to become a BBS Associate, please reply by EMAIL within three (3) weeks to: calls(a)bbsonline.org The Calls are sent to 10,000 BBS Associates, so there is no expectation (indeed, it would be calamitous) that each recipient should comment on every occasion! Hence there is no need to reply except if you wish to comment, or to suggest someone to comment. If you are not a BBS Associate, please approach a current BBS Associate (there are currently over 10,000 worldwide) who is familiar with your work to nominate you. All past BBS authors, referees and commentators are eligible to become BBS Associates. An electronic list of current BBS Associates is available at this location to help you select a name: http://www.bbsonline.org/Instructions/assoclist.html (please note that this list is being updated) If no current BBS Associate knows your work, please send us your Curriculum Vitae and BBS will circulate it to appropriate Associates to ask whether they would be prepared to nominate you. (In the meantime, your name, address and email address will be entered into our database as an unaffiliated investigator.) ======================================================================= ** IMPORTANT ** ======================================================================= To help us put together a balanced list of commentators, it would be most helpful if you would send us an indication of the relevant expertise you would bring to bear on the paper, and what aspect of the paper you would anticipate commenting upon. (Please note that we only request expertise information in order to simplify the selection process.) Please DO NOT prepare a commentary until you receive a formal invitation, indicating that it was possible to include your name on the final list, which is constructed so as to balance areas of expertise and frequency of prior commentaries in BBS. To help you decide whether you would be an appropriate commentator for this article, an electronic draft is retrievable at the URL that follows the abstract and keywords below. ======================================================================= ======================================================================= The Signal Functions of Early Infant Crying Joseph Soltis National Institutes of Health ABSTRACT: In this article I evaluate recent attempts to illuminate the human infant cry from an evolutionary perspective. Infants are born into an uncertain parenting environment, which can range from indulgent care of offspring to infanticide. Infant cries are in large part adaptations that maintain proximity to and elicit care from caregivers. There is not strong evidence for acoustically distinct cry types, however, but infant cries may function as a graded signal. During pain-induced autonomic nervous system arousal, for example, neural input to the vocal cords increases cry pitch. Caregivers may use this acoustic information, together with other cues, to guide care-giving behavior. Serious pathology, on the other hand, results in chronically and severely abnormal cry acoustics. Such abnormal crying may be a proximate cause of adaptive infant maltreatment, in circumstances in which parents cut their losses and reduce or withdraw investment from infants with low survival chances. An increase in the amount of crying during the first few months of life is a human universal, and excessive crying, or colic, represents the upper end of this normal increase. Potential signal functions of excessive crying include manipulation of parents to acquire additional resources, honest signaling of need, and honest signaling of vigor. Current evidence does not strongly support any of these hypotheses, but the evidence is most consistent with the hypothesis that excessive early infant crying is a signal of vigor that evolved to reduce the risk of a reduction or withdrawal of parental care. KEYWORDS: colic, crying, early infant crying, honest signaling, infanticide, parental care, parent-offspring conflict, separation call, vocalization. http://www.bbsonline.org/Preprints/Soltis-11072002/Referees/ ======================================================================= ======================================================================= *** SUPPLEMENTARY ANNOUNCEMENT *** (1) Call for Book Nominations for BBS Multiple Book Review In the past, Behavioral and Brain Sciences (BBS) had only been able to do 1-2 BBS multiple book treatments per year, because of our limited annual page quota. BBS's new expanded page quota will make it possible for us to increase the number of books we treat per year, so this is an excellent time for BBS Associates and biobehavioral/cognitive scientists in general to nominate books you would like to see accorded BBS multiple book review. (Authors may self-nominate, but books can only be selected on the basis of multiple nominations.) It would be very helpful if you indicated in what way a BBS Multiple Book Review of the book(s) you nominate would be useful to the field (and of course a rich list of potential reviewers would be the best evidence of its potential impact!). *-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-*-* Please note: Your email address has been added to our user database for Calls for Commentators, the reason you received this email.
