Infants' use of social partnerships to predict behavior

The experiences of social partners are important motivators of social action. Can infants use such experiences to make predictions about how social agents will behave? Sixteen‐month‐old infants were introduced to two social pairs. Initial events established within‐pair cooperation as well as between‐pair conflict involving an individual from each pair. Following these events, infants looked longer when between‐pair members who had never previously interacted now cooperated – instead of conflicted – with each other. Thus, infants tracked the third‐person allegiances and inferred that the conflict would generalize across social partnerships. These findings demonstrate a critical feature of early social cognition and promote needed, further research on the role of social allegiances in social cognition across development.     

Tricks of Memory

Remembering an episode from even the recent past may involve a blend of fiction and fact. We discuss a straight-forward laboratory paradigm that is proving useful in the study of false memories of simple episodes. In this paradigm, subjects study lists of 15 related words ( bed, rest, awake ...) that are all related to a critical word that is not presented ( sleep ). Later, subjects recall and recognize the critical missing word with about the same probability that they remember words from the list. This memory illusion is resistant to people's attempts to avoid it. We argue that similar memory errors are commonplace and are a natural outcome of an intelligent cognitive system, which makes inferences about incoming information. Therefore, memory illusions, like perceptual illusions, are a consequence of normal human information processing and offer a window for examining basic cognitive processes.     

The Iowa Child Welfare Research Station and the 1940 debate on intelligence: Carrying on the legacy of a concerned mother

During the late 1930s and early 1940s the nature-nurture issue regarding intelligence generated considerable controversy. The focus of attention for this debate was the Thirty-Ninth Yearbook of the National Society for the Study of Education, published in 1940. The Iowa Child Welfare Research Station played a prominent role in this debate. The Iowa researchers, led by George D. Stoddard and Beth L. Wellman, advocated an environmentalist position which challenged the more established hereditarian position held by Lewis M. Terman and his research associates. The Iowa position was closely related to the institutional context of the Child Welfare Research Station.     

Police perspectives on responding to mentally ill people in crisis: perceptions of program effectiveness

In this study, we sampled sworn police officers from three law enforcement agencies (n=452), each of which had different system responses to mentally ill people in crisis. One department relies on field assistance from a mobile mental health crisis team, a second has a team of officers specially trained in crisis intervention and management of mentally ill people in crisis, and a third has a team of in-house social workers to assist in responding to calls. Calls involving mentally ill people in crisis appear to be frequent and are perceived by most of the officers to pose a significant problem for the department; however, most officers reported feeling well prepared to handle these calls. Generally, officers from the jurisdiction with a specialized team of officers rated their program as being highly effective in meeting the needs of mentally ill people in crisis, keeping mentally ill people out of jail, minimizing the amount of time officers spend on these calls, and maintaining community safety. Officers from departments relying on a mobile crisis unit (MCU) and on police-based social workers both rated their programs as being moderately effective on each of these dimensions except for minimizing officer time on these calls where the MCU had significantly lower ratings. © 1998 John Wiley & Sons, Ltd.
