Walton's Argumentation Schemes for Presumptive Reasoning: A Critique and Development

The aim of the paper is to advance the theory of argument or inference schemes by suggesting answers to questions raised by Walton's Argumentation Schemes for Presumptive Reasoning (1996), specifically on: the relation between argument and reasoning; distinguishing deductive from presumptive schemes, the origin of schemes and the probative force of their use; and the motivation and justification for their associated critical questions.     

Palm Beach County Child Abuse and Neglect System Redesign: Initial Process Evaluation

For the families in Palm Beach County who entered the child abuse and neglect system as a result of having a child placed into emergency shelter, their experience was that the system was frequently intimidating, confusing, and fragmented. The reaction of the children and their families to this system was often defensiveness and resistance. To increase the system's effectiveness, it was redesigned and privatized. The redesigned system included centralized shelter placement, a comprehensive assessment, independent service coordination, and treatment service provision within a managed care model. By emphasizing family involvement and quality service provision, the goal was to increase voluntary participation and improve family outcomes. Based on initial data, it appears that the redesigned system has been successfully implemented and has made notable progress toward meeting its system flow timeframes. The initial data also indicate that high percentages of families are participating in and are satisfied with the system, that children are spending less time in shelter placements, and that only one family has reentered the system.     

Characteristics of Children Presenting to a Behavioral Treatment Program for Pediatric Headache

This study examined headache characteristics and psychological variables associated with pediatric headache in a specialty treatment clinic. Children were referred by pediatric neurologists to a hospital-based pediatric behavioral medicine clinic for behavioral treatment in conjunction with medical management of the pain. Headache typology of the children indicated that 1/3 of the sample reported at least daily headaches, and a large percentage of patients described experiencing headaches that lasted for more than a day (26%). Child and parent report of pain revealed a fairly high level of correspondence for headache activity. Regarding other psychological characteristics, children in this study endorsed higher than expected levels of somatization even after adjusting for headache symptoms. Compared with children's report, parents' report showed only slightly higher levels of secondary gain experienced by children because of pain. Gender differences were not found. The implications of these findings for improving our understanding of pediatric headache are discussed.     

Problem Solving Therapy

This paper describes how problem solving therapy (PST) would be applied to the treatment of Sylvia (I. Caro, 2001), a 27-year-old depressed wife and mother of three. PST involves training individuals in five major processes: problem orientation, problem definition and formulation, generation of alternatives, decision making, and solution implementation and verification. We briefly describe a problem solving model of depression that highlights the moderating nature of problem solving ability regarding the stress–depression relationship. Based on this model, we then delineate how PST can be specifically applied to Sylvia. This is followed by a brief overview of the research base supporting the efficacy of PST for depression.     

Belief in a Just World and Condom Use in a Sample of Gay and Bisexual Men1

Research has shown that, under certain conditions, people with a strong belief in a just world (BJW) perceive themselves to be less at risk for serious negative events (e.g., contracting AIDS). We extended this work by investigating the relation between BJW and high‐risk sexual behavior Gay and bisexual men (N= 102) responded to a questionnaire that measured individual differences in BJW, personality characteristics related to perceived relationship threat (e.g., interpersonal control), and frequency of condom use and anal intercourse. Results generally supported predictions. For example, among respondents low in interpersonal control, a strong BJW was associated with less frequent condom use. These results have implications for research on BJW, as well as research on the predictors of high‐risk sexual behavior.     

Scholastic Attainment Following Severe Early Institutional Deprivation: A Study of Children Adopted from Romania

The relationship between severe early institutional deprivation and scholastic attainment at age 11 in 127 children (68 girls and 59 boys) adopted from institutions in Romania was compared to the attainment of 49 children (17 girls and 32 boys) adopted within the UK from a non-institutional background. Overall, children adopted from Romania had significantly lower attainment scores than those adopted within the UK; the children within the Romanian sample who had spent 6 months or more in an institution had significantly lower attainment scores than those who had spent less than 6 months in an institution, but there was no additional risk of low attainment associated with longer institutional care after 6 months. The lower scholastic attainment in the children adopted from Romanian institutions, as compared with domestic adoptees, was mediated by IQ, and to a lesser degree, inattention/overactivity. When these factors were taken into account, only small between-group differences in attainment remained.     

Individual differences in epistemic style: A dual-process perspective

This article reports the results of using a specially designed scaled questionnaire to investigate the dualistic properties of epistemic style. The scale is introduced as a measure of individual difference in epistemic style, conceptualized within the framework of dual-process notions of cognitive function. The study examined several psychometric components of the measure, including dimensional structure, distributional characteristics, and indications of construct validity. The instrument, called the Epistemic Preference Indicator, was found to be a reliable and valid measure of two dimensions that are negatively related—each reflecting incompatible epistemic assumptions and approaches to solving knowledge-dependent problems. Theoretical speculations are made concerning the nature of epistemic dualism and the dimension of cognitive processing that may underlie the two proposed epistemic preferences or styles.     

The discrimination of natural movement by budgerigars (Melopsittacus undulates) and pigeons (Columba livia)

Three experiments examined the ability of birds to discriminate between the actions of walking forwards and backwards as demonstrated by video clips of a human walking a dog. Experiment 1 revealed that budgerigars (Melopsittacus undulates) could discriminate between these actions when the demonstrators moved consistently from left to right. Test trials then revealed that the discrimination transferred, without additional training, to clips of the demonstrators moving from right to left. Experiment 2 replicated the findings from Experiment 1 except that the demonstrators walked as if on a treadmill in the center of the display screen. The results from the first 2 experiments were replicated with pigeons in Experiment 3. The results cannot be explained if it is assumed that animals rely on static cues, such as those derived from individual postures, in order to discriminate between the actions of another animal. Instead, this type of discrimination appears to be controlled by dynamic cues derived from changes in the posture of the demonstrators.     

The role of drug expectancy in the control of human drug seeking

Human drug seeking may be goal directed in the sense that it is mediated by a mental representation of the drug or habitual in the sense that it is elicited by drug-paired cues directly. To test these 2 accounts, the authors assessed whether a drug-paired stimulus (S+) would transfer control to an independently trained drug-seeking response. Smokers were trained on an instrumental discrimination that established a tobacco S+ in Experiment 1 and a tobacco and a money S+ in Experiment 2 that elicited an expectancy of their respective outcomes. Participants then learned 2 new instrumental responses, 1 for each outcome, in the absence of these stimuli. Finally, in the transfer test, each S+ was found to augment performance of the new instrumental response that was trained with the same outcome. This outcome-specific transfer effect indicates that drug-paired stimuli controlled human drug seeking via a representation or expectation of the drug rather than through a direct stimulus-response association.     

Automatic and self-reported attitudes in romantic relationships

Two studies used response latency measures to assess automatic attitudes that individuals are unwilling or unable to reveal about their partners. In Study 1, participants (n = 51) in dating relationships completed two response latency measures (Time 1) and several relationship self-reports (Times 1 and 2). Participants who faced high barriers to exiting (BTE) their relationship generally showed a negative association between their relationship self-reports and automatic attitudes, and there was some evidence that automatic attitudes at Time 1 predicted relationship satisfaction at Time 2. Study 2 (n = 41 couples) replicated the BTE finding and showed that image-based response latency measures may assess automatic attitudes more effectively than word-based measures. A negative correlation between self-reported and automatic attitudes among high-BTE participants suggests that they may overreport relationship positivity to quell feelings of doubt about a relationship they cannot feasibly dissolve.
