Dynamic decision making: a comparison of approaches

This paper is concerned with a specific type of problem, namely dynamic decisions, for which most techniques fail to provide adequate solutions. Here, we present two of the most promising optimization techniques, partially observable Markov decision processes (POMDP) and dynamic decision networks (DDN), while arguing which is the most suitable for this problem domain.

Recidivism base rates,predictions of sex offender recidivism,and the “sexual predator” commitment laws

Predictions of future sexual offending have been mandated by various “Sexual Predator” commitment laws, despite historical arguments that clinicians are frequently inaccurate and over-predict violence. The basis for those arguments has been the perspective that sexual recidivism is a relatively rare event. Research is reviewed, however, with the finding that sexual recidivism for certain offenders is a rather common occurrence when the definition of recidivism is in keeping with the sex offender commitment laws. This finding is used to demonstrate that under-, rather than over-prediction of the designated violence is necessarily today's practice. Practical and ethical implications are discussed. © 1998 John Wiley & Sons, Ltd.     

Attitude Toward Christianity and Psychological Type: A Survey Among Religious Studies Students

A sample of 367 students studying religion at A-level completed the Keirsey Temperament Sorter together with the Francis Scale of Attitude Toward Christianity. The data demonstrated that sensing types hold a more positive attitude toward Christianity than intuitive types and that judging types hold a more positive attitude toward Christianity than perceiving types. No significant differences in attitude toward Christianity were found either between extroverts and introverts, or between thinking types and feeling types.     

At what age are children most likely to be bullied at school?

Cross‐sectional questionnaire surveys of school bullying reliably find that the frequency of incidents falls with age. However, it is not clear how much of this decline is due to a real change in behaviour, and how much to children’s changing definitions of what bullying is. This paper presents the results of two retrospective studies in an attempt to assess at what ages bullying is really most likely to occur. Male and female adults aged 18–55 years (n¹ = 205 and n² = 200) completed questionnaires about their memories of being bullied at school. Results showed that bullying was most frequently remembered from around 11–13 years of age, with incidents from earlier and later childhood being reported comparatively rarely. There were no differences between the reports of younger (18–21 years) and older (22–55 years) participants or between those of males and females. Bullying memories were also compared with memories for other aspects of childhood to assess the accuracy of these memories. It is concluded that the most memorable (and therefore perhaps the most severe) bullying is that which occurs in middle childhood. Aggr. Behav. 27:419–429, 2001. © 2001 Wiley‐Liss, Inc.     

Understanding of literal truth, ironic criticism, and deceptive praise following childhood head injury.

Children with closed head injury (CHI) have semantic-pragmatic language problems that include difficulty in understanding and producing both literal and nonliteral statements. For example, they are relatively insensitive to some of the social messages in nonstandard communication as well as to words that code distinctions among mental states. This suggests that they may have difficulty with comprehension tasks involving first- and second-order intentionality, such as those involved in understanding irony and deception. We studied how 6- to 15-year-old children, typically developing or with CHI, interpret scenarios involving literal truth, ironic criticism, and deceptive praise. Children with severe CHI had overall poorer mastery of the task. Even mild CHI impaired the ability to understand the intentionality underlying deceptive praise. CHI, especially biologically significant CHI, appears to place children at risk for failure to understand language as externalized thought.     

The Law Says Corporations are Persons,but Psychology Knows Better

Psychologists interested in law and public policy have begun to examine the nature of corporations in American society and the serious consequences of corporate irresponsibility. The dominant trend identifies areas where corporate behavior falls short of ethical standards or leads to unacceptably risky decisions and suggests ways to reform corporations or the laws that regulate them. This well-intentioned approach is consistent with psychology's liberal reformist tendency. Unfortunately, it neither challenges the flawed psychological underpinnings of the legal fiction that corporations are legal persons nor compensates sufficiently for the dynamics of individual behavior in corporate settings. Instead, psychologists should advocate fundamental restructuring of our corporate society.     

Refugees in the media: Exploring a vicious cycle of frustrated psychological needs,selective exposure,and hostile intergroup attitudes

Two research objectives underlay the present research. First, we tested how frustrated psychological needs caused by the refugee-influx influence the endorsement and selection of refugee-relevant information. Second, we tested how information selection processes contribute to the development of exclusionary attitudes that counteract the integration of refugees into host countries. In a laboratory study (n = 181), frustrated psychological needs decreased participants’ endorsement of a refugee-friendly essay (vs. a control essay). Additionally, frustrated needs led to a biased selection of refugee-hostile over refugee-friendly information and such selection biases, in turn, predicted higher levels of ingroup defense and prejudice toward refugees. The findings imply that host societies’ receptiveness to refugees is influenced by the maintenance of basic psychological needs.
