The locality and globality of instrumental rationality: the normative significance of preference reversals

When we ask a decision maker to express her preferences, it is typically assumed that we are eliciting a pre-existing set of preferences. However, empirical research has suggested that our preferences are often constructed on the fly for the decision problem at hand. This paper explores the ramifications of this empirical research for our understanding of instrumental rationality. First, I argue that these results pose serious challenges for the traditional decision-theoretic view of instrumental rationality, which demands global coherence amongst all of one’s beliefs and desires. To address these challenges, I first develop a minimal notion of instrumental rationality that issues in localized, goal-relative demands of coherence. This minimal conception of instrumental rationality is then used to offer a more sophisticated account of the global aspects of instrumental rationality. The resulting view abandons all-or-nothing assessments of rationality and allows us to evaluate decision makers as being rational to varying degrees. My aim is to propose a theory that is both psychologically and normatively plausible.     

The evidence base for family therapy and systemic interventions for child‐focused problems

This review updates similar articles published in the Journal of Family Therapy in 2001 and 2009. It presents evidence from meta‐analyses, systematic literature reviews and controlled trials for the effectiveness of systemic interventions for families of children and adolescents with various difficulties. In this context, systemic interventions include both family therapy and other family‐based approaches such as parent training. The evidence supports the effectiveness of systemic interventions either alone or as part of multi‐modal programmes for sleep, feeding and attachment problems in infancy; child abuse and neglect; conduct problems (including childhood behavioural difficulties, attention deficit hyperactivity disorder, delinquency and drug misuse); emotional problems (including anxiety, depression, grief, bipolar disorder and self‐harm); eating disorders (including anorexia, bulimia and obesity); somatic problems (including enuresis, encopresis, medically unexplained symptoms and poorly controlled asthma and diabetes) and first episode psychosis.     

The Use of Mobile Devices in High‐stakes Remotely Delivered Assessments and Testing

With Internet access no longer restricted to desktop and laptop computers, job applicants now have the opportunity to complete remotely delivered assessments on mobile, handheld small screen devices such as smartphones, and personal digital assistants. In this study, a large dataset is used to investigate demographic and score differences between job applicants who completed a remotely delivered high‐stakes assessment on a mobile device and those who completed it on a nonmobile device. Based on a sample of 3,575,207 job applicants who completed an unproctored Internet‐based assessment between January 2011 and April 2012, the percentage of applicants completing the assessment on a mobile device was small, 1.93%, but nevertheless represented more than 69,000 people. Overall, there were small test‐taker demographic differences in the use of mobile devices versus nonmobile devices in that mobile devices were slightly more likely to be used by women, African‐Americans and Hispanics, and younger applicants. Scores on a personality measure were similar for mobile and nonmobile devices but scores on a general mental ability test were substantially lower for mobile devices. Tests of measurement invariance also indicated equivalence across the mobile and nonmobile samples. Test taker and organizational implications for completing remotely delivered high‐stakes noncognitive and cognitive assessments on mobile versus nonmobile devices are discussed.     

The ecology of spatial memory in four lemur species

Evolutionary theories suggest that ecology is a major factor shaping cognition in primates. However, there have been few systematic tests of spatial memory abilities involving multiple primate species. Here, we examine spatial memory skills in four strepsirrhine primates that vary in level of frugivory: ruffed lemurs (Varecia sp.), ring-tailed lemurs (Lemur catta), mongoose lemurs (Eulemur mongoz), and Coquerel’s sifakas (Propithecus coquereli). We compare these species across three studies targeting different aspects of spatial memory: recall after a long-delay, learning mechanisms supporting memory and recall of multiple locations in a complex environment. We find that ruffed lemurs, the most frugivorous species, consistently showed more robust spatial memory than the other species across tasks—especially in comparison with sifakas, the most folivorous species. We discuss these results in terms of the importance of considering both ecological and social factors as complementary explanations for the evolution of primate cognitive skills.     

UTILIZATION OF VIDEO MODELING COMBINED WITH SELF‐MONITORING TO INCREASE RATES OF ON‐TASK BEHAVIOR

The study investigated the effectiveness of an intervention package consisting of self‐monitoring and video modeling to increase on‐task behavior during independent seatwork time in math. Four students in either the second or third grade, identified as displaying high rates of off‐task behavior by their classroom teacher, were included in the study. Results showed immediate, large, and durable changes in on‐task behavior for each of the four participants. At baseline, on‐task behavior of the participants while working on independent math assignments was displayed in 47% of the intervals observed. During the intervention, the participants' average rate of on‐task behavior increased to 85% of the intervals observed. Mean Busk and Serlin (1994) effect size for all four participants was 5.60, with a percentage of non‐overlapping data points effect size of 100%. Observations of the participants 3 weeks following the termination of the study showed that the gains in on‐task behavior were maintained. Both teacher and participant feedbacks concerning the use and effectiveness of the intervention package were positive. Results of the investigation suggest that the intervention package may be an effective and socially valid method for addressing off‐task behaviors of students within the classroom.

APPLIED BEHAVIOR ANALYSIS IN ACQUIRED BRAIN INJURY REHABILITATION: A META‐ANALYSIS OF SINGLE‐CASE DESIGN INTERVENTION RESEARCH

The purpose of this meta‐analysis was to complete a systematic evidence‐based review of published behavioral treatment studies employing single‐case designs with both children and adults with acquired brain injury. Peer‐reviewed journals were searched using PsycINFO, Medline, and ERIC databases with combinations of terms such as brain injury, behavior disorder, behavior therapy, behavior modification, behavior analysis, and verbal behavior. A total of 112 acquisition and reduction studies met the established inclusion criteria. The data extracted from each study included specific details about the participants, target responses, intervention characteristics, use of functional assessment, and outcome characteristics. A data extraction software program was also used to extract data from graphs to calculate percentage of nonoverlapping data as an effect size_. The studies were then evaluated along several dimensions from multiple evidence‐based practice frameworks. Collectively, interventions targeted a wide range of behaviors for acquisition and reduction, but only five interventions were classified as well established according to the American Psychological Association Division 12 criteria. Furthermore, methodology of the identified studies was found to be relatively poor. A variety of methodological concerns are discussed. Copyright © 2014 John Wiley & Sons, Ltd.     

A DISCRIMINATION TRAINING PROCEDURE TO ESTABLISH CONDITIONED REINFORCERS FOR CHILDREN WITH AUTISM

Although conditioned reinforcers are used in many behavioral intervention programs for individuals with developmental disabilities, little research has been conducted to determine optimal methods for establishing conditioned reinforcers. An early method that has received relatively little research attention is to condition a neutral stimulus as a discriminative stimulus and then use the stimulus as a programed consequence during skill acquisition. The current study evaluated the effects of a discrimination training procedure on establishing conditioned reinforcers for three children with autism. For all participants, previously neutral stimuli reinforced behaviors after acquiring discriminative properties during discrimination training. Copyright © 2014 John Wiley & Sons, Ltd.     

Examining Adolescent Cocaine Use with Social Learning and Self-Control Theories

An estimated 1.6 million adolescents use cocaine on a regular basis. Social learning theory and self-control theory are regularly used to explain adolescent substance use, but few studies have examined Hirschi’s (2004) revised self-control theory. This study examines the efficacy of these three theories in explaining adolescent cocaine use using data from the 2011 Monitoring the Future survey. The study finds that Hirschi’s (2004) revised theory and peer hard drug use predicted the probability of adolescent cocaine use in the previous 30 days. When examining cocaine use in the prior year, all three theoretical perspectives were significant predictor of cocaine use. The implications of the findings are discussed.
