What should we expect after the next attack?

A test of any science is its ability to predict events under specified conditions. A test for the psychology represented in this special issue of the American Psychologist is its ability to predict individual and social behavior in the aftermath of a next terror attack. This article draws on that science to make such predictions. These predictions are conditioned on both the nature of the attack and our institutional preparations for it. Some attacks will test our resilience more than others. Whatever the attack, we will reduce its impacts if our institutions take advantage of psychological science. That science can reduce the scope of attacks by limiting terrorists' ability to organize their operations and by enhancing our ability to restrain them. It can reduce the impacts of any attacks that do occur by strengthening the institutions and civil society that must respond to them. Realizing these possibilities will require our social institutions to rely on science, rather than intuition, in dealing with these threats. It will require our profession to provide psychologists with rewards for public service, applied research, and interdisciplinary collaboration, as demanded by complex problems. Responding to these challenges could strengthen society and psychology.     

The what–where trade-off in multiple-identity tracking

Observers are poor at reporting the identities of objects that they have successfully tracked (Pylyshyn, Visual Cognition, 11, 801-822, 2004; Scholl & Pylyshyn, Cognitive Psychology, 38, 259-290, 1999). Consequently, it has been claimed that objects are tracked in a manner that does not encode their identities (Pylyshyn, 2004). Here, we present evidence that disputes this claim. In a series of experiments, we show that attempting to track the identities of objects can decrease an observer's ability to track the objects' locations. This indicates that the mechanisms that track, respectively, the locations and identities of objects draw upon a common resource. Furthermore, we show that this common resource can be voluntarily distributed between the two mechanisms. This is clear evidence that the location- and identity-tracking mechanisms are not entirely dissociable.     

The role of Gestalt grouping principles in visual statistical learning

A major issue in visual scene recognition involves the extraction of recurring chunks from a sequence of complex scenes. Previous studies have suggested that this kind of learning is accomplished according to Bayesian principles that constrain the types of extracted chunks. Here we show that perceptual grouping cues are also incorporated in this Bayesian model, providing additional evidence for the possible span of chunks. Experiment 1 replicates previous results showing that observers can learn three-element chunks without learning smaller, two-element chunks embedded within them. Experiment 2 shows that the very same embedded chunks are learned if they are grouped by perceptual cues, suggesting that perceptual grouping cues play an important role in chunk extraction from complex scenes.     

Trauma-Focused CBT for Traumatic Grief in Military Children

Although military children are typically as resilient as the general child population, the ongoing conflict has exposed military children to unusual stressors such as repeated deployment, severe injury, or the death of a parent or sibling. U.S. forces have experienced more than 5,600 casualties during Operation Iraqi Freedom and Operation Enduring Freedom, with growing numbers of suicides among Service members. These deaths have affected thousands of military children. Most bereaved military children experience adaptive grief characterized by deep sadness, longing for the deceased person, and being comforted by positive memories of the deceased. A smaller number of military children develop childhood traumatic grief, characterized by trauma symptoms that interfere with adaptive grieving. Children with traumatic grief get “stuck” on the traumatic aspects of the death such as picturing the imagined or real details of the death; imagining the pain their loved one experienced in the moments before dying; wishing for revenge; and becoming angry at those who do not understand or share the child’s thoughts and feelings about the death. These children avoid reminders of the deceased person. Trauma-focused cognitive behavioral therapy (TF-CBT) is an evidence-based treatment for children with trauma symptoms including those with traumatic grief. TF-CBT may be particularly suitable for military families. This article describes the clinical application of TF-CBT for traumatic grief in military children.     

Parenting of 7‐month‐old infants at familial risk for attention deficit/hyperactivity disorder

Patterns of interaction between parents and 7‐month‐old boys at familial risk for attention deficit/hyperactivity disorder (ADHD) and a comparison group were studied during a warm‐up and two play episodes. The sample included 78 (47 at‐risk, 31 comparison) mother–child and 45 (27 at‐risk, 18 comparison) father–child dyads. A coding system developed by G. Kochanska (1997, 1998) was used. Infants in the risk group did not differ from the comparison group in the rate of emission of infant‐related events. However, they received less adequate responsivity from both their fathers and their mothers to these events, and specifically to negative emotions or distress, than did the comparison group. Maternal psychopathology did not account for these findings. Mothers were more adequately responsive than were fathers, especially for physiological needs. The association between nonoptimal interaction in infancy and the development of ADHD is discussed.     

International stem cell tourism and the need for effective regulation. Part II: Developing sound oversight measures and effective patient support

Part I of this article, published in the March 2010 issue of the Kennedy Institute of Ethics Journal, traces and addresses the provision of unproven stem cell treatments in Russia and India, examines the concept of innovative treatment, and concludes that stronger regulations are needed to protect the health and informed choices of patients. The current paper, Part II, proposes that the regulatory frameworks for the development of safe and efficacious treatments in effect in the United States and the United Kingdom provide examples of strong oversight measures from which countries seeking to obtain international credibility for their biotechnological competence could draw when developing regulations for stem cell treatments. Major sources of information available to persons who consider receiving such unproven treatments are explored in order to understand and address their concerns. The paper concludes with proposed measures to inform those considering the pursuit of unproven stem cell treatments abroad more accurately about their efficacy and safety and provide them with improved medical and social support in their home countries.     

Mindful Parenting: A Call for Research

Interest in mindfulness-based interventions for children and adolescents is growing, but despite substantial evidence that parental distress and psychopathology adversely affects children, there is little research on how mindfulness-based parenting interventions might benefit the child as well as the parent. As an established intervention for prevention of depressive relapse, mindfulness-based cognitive therapy (MBCT) conducted with parents is an intervention that potentially could improve parent–child relationships, reduce child symptoms, and promote healthy child development. Mindful parenting interventions bring mindful attention directly to parent–child interactions and are similar but not identical to existing clinical mindfulness interventions such as MBCT. Mindfulness-based parenting interventions have an interpersonal, rather than intrapsychic focus, with particular attention given to the parent–child relationship. Preliminary research suggests that this intervention approach may reduce stress, enhance parenting satisfaction, decrease child aggression, and increase children’s prosocial behaviors. Initial evidence supporting the effectiveness of mindful parenting programs is promising and supports our call for ongoing research.     

Pupil diameter tracks changes in control state predicted by the adaptive gain theory of locus coeruleus function

An important dimension of cognitive control is the adaptive regulation of the balance between exploitation (pursuing known sources of reward) and exploration (seeking new ones) in response to changes in task utility. Recent studies have suggested that the locus coeruleus-norepinephrine system may play an important role in this function and that pupil diameter can be used to index locus coeruleus activity. On the basis of this, we reasoned that pupil diameter may correlate closely with control state and associated changes in behavior. Specifically, we predicted that increases in baseline pupil diameter would be associated with decreases in task utility and disengagement from the task (exploration), whereas reduced baseline diameter (but increases in task-evoked dilations) would be associated with task engagement (exploitation). Findings in three experiments were consistent with these predictions, suggesting that pupillometry may be useful as an index of both control state and, indirectly, locus coeruleus function.     

Are Arabic and verbal numbers processed in different ways?

Four experiments were conducted in order to examine effects of notation--Arabic and verbal numbers--on relevant and irrelevant numerical processing. In Experiment 1, notation interacted with the numerical distance effect, and irrelevant physical size affected numerical processing (i.e., size congruity effect) for both notations but to a lesser degree for verbal numbers. In contrast, size congruity had no effect when verbal numbers were the irrelevant dimension. In Experiments 2 and 3, different parameters that could possibly affect the results, such as discriminability and variability (Experiment 2) and the block design (Experiment 3), were controlled. The results replicated the effects obtained in Experiment 1. In Experiment 4, in which physical size was made more difficult to process, size congruity for irrelevant verbal numbers was observed. The present results imply that notation affects numerical processing and that Arabic and verbal numbers are represented separately, and thus it is suggested that current models of numerical processing should have separate comparison mechanisms for verbal and Arabic numbers.
