Intelligence is associated with criminal justice processing: Arrest through incarceration

Findings flowing from empirical research consistently indicate that IQ is associated with criminal involvement, with persons of relatively lower IQ being more likely to engage in various types of crime when compared with persons of relatively higher IQ. As with all research, however, there are a number of limitations with the existing literature that may bias the IQ–crime connection in unknown ways. Specifically, previous research has generally analyzed sub-samples drawn from non-nationally representative samples, has relied on a narrow range of criminal justice measures, has not fully examined whether the IQ–crime link is observed across demographic subgroups, and has not always ruled out the effects of potential confounds. The current study is designed to overcome the most serious of these limitations and offer new evidence of the link between IQ and criminal involvement. Analysis of data drawn from the National Longitudinal Study of Adolescent Health (Add Health) provides strong evidence indicating that IQ and crime are linked even after addressing various shortcomings of previous research. Limitations of the study are discussed and directions for future research are offered.     

Assessment and treatment of elopement maintained by access to stereotypy

We evaluated a treatment for elopement maintained by access to stereotypic door play. First, we conducted a functional analysis of elopement that produced undifferentiated results. Next, we conducted an assessment in which we evaluated the relation between elopement and door play. Results suggested a functional relation between the 2 behaviors (i.e., elopement was maintained by contingent access to door play). Finally, we implemented functional communication training as a treatment for elopement in which access to door play was made contingent on a target appropriate communication response.     

The testing effect in free recall is associated with enhanced organizational processes

In two experiments with categorized lists, we asked whether the testing effect in free recall is related to enhancements in organizational processing. During a first phase in Experiment 1, subjects studied one list over eight consecutive trials, they studied another list six times while taking two interspersed recall tests, and they learned a third list in four alternating study and test trials. On a test 2 days later, recall was directly related to the number of tests and inversely related to the number of study trials. In addition, increased testing enhanced both the number of categories accessed and the number of items recalled from within those categories. One measure of organization also increased with the number of tests. In a second experiment, different groups of subjects studied a list either once or twice before a final criterial test, or they studied the list once and took an initial recall test before the final test. Prior testing again enhanced recall, relative to studying on the final test a day later, and also improved category clustering. The results suggest that the benefit of testing in free recall learning arises because testing creates retrieval schemas that guide recall.     

Conditional reasoning,frequency of counterexamples,and the effect of response modality

Geiger and Oberauer (2007) found that when asked to reason with conditionals, people are very sensitive to information about the relative frequency of exceptions to conditional rules and quite insensitive to the relative number of disabling conditions. They asked participants to rate their degree of certainty in a conclusion. In the following studies, we investigated the possibility that this kind of response encourages a more probabilistic mode of processing compared with the usual dichotomous response. In Study 1, participants were given a variant of the problems used by Geiger and Oberauer with either the samescaled response format or a dichotomouscategorical response. The results with the scaled response were identical to those of Geiger and Oberauer. However, the results with the categorical response presented a very different profile. In Study 2, we presented similar problems using only frequency information, followed by a set of abstract conditional reasoning problems. The participants who performed better on the abstract problems showed a significantly different response profile than those who did worse on the abstract problems in the categorical response condition. No such difference was observed in the scaled response condition. These results show that response modality strongly affects the way in which information is processed in otherwise identical inferential problems and they are consistent with the idea that scaled responses promote a probabilistic mode of processing.     

Building esprit de corps: learning to better navigate between "my" patient and "our" patient

Excellence in the care of hospital patients, particularly those in an intensive care unit, reflects esprit de corps among the care team. Esprit de corps depends on a delicate balance; each clinician must preserve a sense of personal responsibility for "my" patient and yet participate in the collaborative work essential to the care of "our" patient. A harmful imbalance occurs when a physician demands total control of the decision-making process, especially concerning end-of-life treatment options. Although emotional factors may push a physician to claim decision-making exclusivity, compounded by a legal framework that overemphasizes individual responsibility, esprit de corps can be preserved through timely communication among clinicians and a recognition that optimal care for "my" patient requires effective team practice.     

Communalism, familism, and filial piety: are they birds of a collectivist feather?

The present studies examined the extent to which (a) communalism, familism, and filial piety would pattern onto a single family/relationship primacy construct; (b) this construct would be closely related to indices of collectivism; and (c) this construct would be related to positive psychosocial functioning and psychological distress. In Study 1, 1,773 students from nine colleges and universities around the United States completed measures of communalism, familism, and filial piety, as well as of individualistic and collectivistic values. Results indicated that communalism, familism, and filial piety clustered onto a single factor. This factor, to which we refer as family/relationship primacy, was closely and positively related to collectivism but only weakly and positively related to individualism and independence. In Study 2, 10,491 students from 30 colleges and universities in 20 U.S. states completed measures of communalism, familism, and filial piety, as well as of positive psychosocial functioning and psychological distress. The family/relationship primacy factor again emerged and was positively associated with both positive psychosocial functioning and psychological distress. Clinical implications and future directions for the study of cultural values are discussed.     

Using video modeling to teach siblings of children with autism how to prompt and reinforce appropriate play

This study investigated the use of video models to teach typically developing children how to prompt and reinforce appropriate play behavior during games with their sibling with autism. With 3 sibling dyads, we extended research on cooperative sibling play by examining video modeling as the sole intervention to facilitate appropriate play between siblings in the absence of specific reinforcement for skills learned in the video model. Video models included brief clips of adults playing games with the child with autism and demonstrating how to prompt and reinforce play behavior. Results indicated that for 2 of the 3 sibling dyads video modeling alone was sufficient to teach prompts and appropriate delivery of reinforcement. An increase in on‐task activity engagement was also observed for both siblings with autism across all 3 dyads.     

Purchase task sensitivity to drug and nondrug reinforcers in opioid-agonist treatment patients

The behavioral economics of substance abuse has been increasingly recognized as a method of determining the value of abused substances for individuals who use those substances. It has been hypothesized that such analyses could serve as a clinical tool and that demand functions can be targeted predictors for the level of intervention necessary. This study evaluated the sensitivity of a demand task in 2 patient groups in a medication assisted treatment program (methadone maintenance), those who had used opioids in the last 2 months and those who had not used opioids in at least 18 months. Demand for 7 drugs and a control was assessed using hypothetical purchase tasks. Participants maintaining long-term abstinence had significantly higher α (sensitivity to price) and lower Q₀ (intensity of demand) for heroin than participants who had recently used opioids. Further research is necessary to illustrate if treatment is responsible for this reduction in demand. If so, demand analyses may provide clinical utility as an aid for treatment planning or as a target for treatment.
