The ecological rationality of state-dependent valuation

Laboratory studies on a range of animals have identified a bias that seems to violate basic principles of rational behavior: a preference is shown for feeding options that previously provided food when reserves were low, even though another option had been found to give the same reward with less delay. The bias presents a challenge to normative models of decision making (which only take account of expected rewards and the state of the animal at the decision time). To understand the behavior, we take a broad ecological perspective and consider how valuation mechanisms evolve when the best action depends upon the environment being faced. We show that in a changing and uncertain environment, state-dependent valuation can be favored by natural selection: Individuals should allow their hunger to affect learning for future decisions. The valuation mechanism that typically evolves produces the kind of behavior seen in standard laboratory tests. By providing an insight into why learning should be affected by the state of an individual, we provide a basis for understanding psychological principles in terms of an animal's ecology.     

Somatoform Disorder: Treatment Utilization and Cost by Mental Health Professions

Administrative data from Cigna for 149 somatoform cases were analyzed to determine the cost, number of sessions, dropout rates, and recidivism rates. Comparisons on these outcomes were made between medical doctors, psychologists, master’s nurses, master’s social workers, marriage and family therapists, and professional counselors. Recidivism rates and number of sessions are higher than for other mental health problems. There were no significant difference in total cost by profession, but did indicate a significant difference in cost per session for MDs. Analyses indicate that masters and doctoral level providers produced the same drop out and recidivism rates.     

Female sexual offenders: Five Italian case studies

Women who sexually abuse children are rare and case histories are scarce; even less is known about sexually abusive mothers. Due to the number of cases in which women sexually abuse minors, more in-depth studies on this subject are needed. This article examines the clinical files of five women who are currently serving time in Italian prisons for the sexual abuse of children. Records of the abuse cases and other records were utilized. The cases involved varying degrees of participation in the abuse by the mothers, and ranged from active sexual engagement to allowing others to abuse their children. Female perpetrators are likely to be experiencing problems in many areas of their life, including relationship dysfunction and psychological impairment. In three cases women revealed an antisocial personality disorder (ASPD), while in two cases a borderline personality disorder (BPD) was diagnosed according with DSM-IV criteria. Possible motivations for women who molest their children are explored and discussed. The current review shows that most female sex offenders fall into several suggested typology models. Therefore, the existing typologies used to classify female child sex offenders may be insufficient, and more comprehensive exploration of this offender population is needed.     

The quality of the analyst's attention

Compiled and edited from lectures on psychoanalytic technique given by the late Karen Horney at the American Institute for Psychoanalysis during the years 1946, 1950, 1951, and 1952. Further lectures in this series will appear in subsequent issues of the Journal.     

Redundancy as a facilitator in the learning of complex verbal forms

A principle to account for mastering of complex linguistic forms was proposed. A total of 149 4- to 6-year-old children were tested to determine whether experience with redundant features (e.g., the word first) in the sentence facilitated later comprehension of equivalent nonredundant sentences expressing temporal order (before, after). The data showed that sentences were scalable as proposed, and that redundancy as a temporal marker facilitated later comprehension, but only for relatively low levels of complexity. Different findings by different experimenters highlight how apparently minor variations in experiments can result in different conclusions about comprehension strategies when one generalizes from studies that use subjects still acquiring language.This research was supported in part by a National Institute of Education grant, Project No. 4-470     

Youth Homelessness and Vulnerability: How Does Couch Surfing Fit?

Youth homelessness is a problem characterized by high levels of vulnerability. The extent to which couch surfing — moving from one temporary housing arrangement to another — is part of youth homelessness is not well understood. Chapin Hall's Voices of Youth Count, a national research initiative, involves a multicomponent approach to studying youth homelessness. This study reports emerging findings regarding couch surfing and homelessness primarily from a national survey of 13,113 adults with youth ages 13–25 in their households or who are themselves ages 18–25. Findings suggest that couch surfing is relatively common, particularly among the older age group. Among households with 13‐ to 17‐year‐olds and 18‐ to 25‐year‐olds, 4.0% and 20.5%, respectively, reported that any of them had couch surfed in the last 12 months. There are notable social, economic, and educational differences, on average, between youth reporting homelessness and those reporting only couch surfing. However, most youth who report experiencing homelessness also report couch surfing, and these youth who experience both circumstances present high levels of socioeconomic vulnerability. Couch surfing encompasses a range of experiences, some of which likely include need for services. Interviews currently in the field, and expanded analysis of data, will contribute more nuanced policy insights.

The cataphoric use of the indefinite this in spoken narratives

Are concepts that were introduced with the unstressed, indefinite articlethis, as opposed to the indefinitea/an, more accessible from listeners’ mental representations? Subjects heard and then verbally continued each of a series of informal narratives. The last clause of each narrative introduced a new noun phrase that began with either the indefinitethis or the indefinitea/an (e.g.,this egg oran egg). When the concepts were introduced with the indefinitethis, the subjects referred to them more frequently, often within the first clauses that they produced, and typically via pronouns. In contrast, when the concepts were introduced witha/an, the subjects referred to them less frequently and typically via full noun phrases. Thus, concepts introduced with the indefinitethis were more accessible; therefore, the indefinitethis appears to operate cataphorically to improve referential access.     

The psychiatric inpatient treatment of children and youth in general hospitals

National attention has recently focused on the mental health needs and services of children and youth. The lack of outpatient services and their coordination has been noted, as well as the consequent press towards inpatient care. We describe the inpatient treatment of children and adolescents (ages 0-18) in short-term, non-Federal general hospitals in 1980. Nationally, 128,300 children were treated for mental disorders in general hospitals at an estimated cost of over $1.5 billion. Compared to adults, children were more likely to be treated in scatter beds (vs. specialty units); have a diagnosis of mental disorder (vs. alcohol/drug disorder); stay much longer; and pay with commercial insurance. Previous work focusing on psychiatric units of general hospitals identified less than 40% of the total episodes, a figure very similar to that for adults. The majority of psychiatric inpatient episodes for children and youth in the United States takes place in short-term general hospitals. Community psychologists need to be aware of national trends in inpatient care and be involved in the development and promulgation of alternative models of care.
