Communication, The Umwelt, and Human Infant Crying PSC 113 Jeff Schank

Outline The Umwelt Again An assessment/management (A/M) approach – Management capitalizes on the assessment systems of targets – Communication involves mutual efforts to regulate one another’s behavior – Communication is based on an organism’s Umwelt Human infant crying – Attachment – Crying is designed to capitalize on motivational and emotional systems of caregivers – What about colic? – The evolutionary origins of crying

Questions about Crying Is crying referentially specific? Is crying a true indicator of specific needs (internal states) of the infant? What effects does crying have on caregivers or potential care givers? Can crying malfunction? How has evolution shaped crying and adult responses to crying?

Umwelt Again We just talked about the perceptive-reactive world of animals Different species have different Umwelten, but as we saw, the perceptive-reactive worlds of organisms change as they develop Humans are not born with language and so an infant cannot “tell” a caregiver what it specifically needs If infants cannot communicate their specific needs, then their needs have to be assessed by caregivers

Assessment/Management (A/M) Don Owings proposed a conceptual framework for theorizing about infant crying as a form of animal communication Don Owings He called his approach the assessment/management (A/M) approach On the A/M approach, communication is an inter-individual process built upon two types of individual activity – Assessment: self-interested behaviors based on the extraction of clues from other individuals and their contexts – Management: self-interested efforts to maintain or change current circumstances, in part, by managing the behavior of others

A/M Examples This fits with the view that communication is at a higher level of organization than the individual Individuals do not have to belong to the same species

The Management Side Management capitalizes on the assessment systems of targets That is, one individual can manipulate the behavior of another by emitting signals that take advantage of the way the target assesses those signals – Signaling (crying) works by capitalizing on the assessment systems of targets (caregivers) – The assessment systems of targets (caregivers) are major determinants of the effectiveness of signaling (crying) at eliciting care giving

Signal Examples

Communication as Mutual Regulation of Behavior Communication on the A/M approach is a system and it can malfunction (e.g., laughing gulls) Evolutionary changes in the A/M system of one type of individual can affect the A/M system of another Is the interaction between predators or parasites and fall webworms communication?

Communication is Based on an Organism’s Umwelt This may create asymmetries in communication In this case, assessment by the caregiver is weak but management by the infants dramatically affects the caregiver’s assessment systems

Umwelt, Attachment, and Crying The notion of attachment comes from early animal behavior research of Konrad Lorenz on imprinting and presupposes the idea of the Umwelt

Umwelt, Attachment, and Crying Similarly, human infants attach to caregivers among the many objects in their Umwelt

Attachment and The Strange Situation On the A/M approach, either assessment or management issues with the caregiver may explain the insecure attachment relationship This is the new component that A/M adds to attachment theory

Secure Attachment When an infant is securely attached to its caregiver, the infant is more willing to explore and interact with the world because the caregiver is the focus of security to which the infant can safely retreat

Insecure Attachment Because the attachment relationship from the point of view of the infant is not secure (or strong), its interaction with the world is much reduced

Assessment/Management View of Attachment Attachment relationship are analyzed in terms of the Umwelten of the child and caregiver A caregiver with strong assessment/management skills is more likely to have a secure attachment relationship with a child A caregiver with weak assessment/management skills is more likely to have an insecure attachment relatioship with a child

Crying Crying is designed to capitalize on motivational and emotional systems of caregivers A paradoxical feature of crying – It’s a signaling system that evolved to solicit caregiving – But it can also be aversive to caregivers that it can at times evoke abuse of the crying infant

What about Colic? On the A/M approach, colic may be a byproduct of cultural evolution in technologically-advanced cultures In Western cultures there is often greater distance maintained between infant and caregiver When an infant is at a great distance from the caregiver, there will be lags in responses In less technologically advanced societies, infant and caregiver are often in very close proximity almost all of the time, so that there are very rapid responses to crying

The Evolutionary Origins of Crying How did crying evolve? It may have first evolved as a byproduct of other physiological processes, and thereby give direct indications of infant distress Ultrasonic “retrieval calls” of infant rats are one possibility Mark Blumberg presented evidence that, in rats, ultrasonic vocalizations have originated as a byproduct Laryngeal braking (involves the constriction of the larynx following inspiration, resulting in prolonged expiratory duration and enhanced gas exchange) to utilize brown adipose tissue for producing heat According Blumberg, – maternal retrieval evoked by ultra sounds originated through a process of active caregiver assessment based on these sounds – And does not require infant management – The sounds are a cue and not a management system
