The Applied Cognitive Psychology of Attention: A Step Closer to Understanding Magic Tricks

Drawing on psychological science, magic provides a unique perspective on applied cognition. Only sparse systematic research, however, documents the thought processes associated with viewing magic tricks. With responses from over 1000 participants, here, we show how individuals construe a classic magic routine wherein a performer appears to vanish a pen. Thirty‐four percent of participants correctly identified the key moment of the disappearance with only 11% thereof knowing what actions the magician actually performed to achieve the effect. Our collective findings support what magicians have known for a long time: knowing when a critical maneuver occurs hardly reveals the associated modus operandi. In line with a modern theory of attention, we discuss our results and highlight the interaction between the when and where attention modules as a necessary component of applied cognition in ecological settings.

Transfer of Skills in the Context of Non‐Suggestive Investigative Interviews: Impact of Structured Interview Protocol and Feedback

Two groups of police investigators were trained in the use of the National Institute of Child Health and Human Development (NICHD) interview protocol. After the training, one group (n = 8) received written feedback on each interview they conducted, whereas the other group (n = 11) did not. The objective of the study was, first, to evaluate the effect of NICHD protocol implementation on the types of questions and details provided by children and, second, to evaluate the impact of post‐training feedback. Interviewees were alleged sexual abuse victims between the ages of 3 and 14 years. Application of the NICHD protocol allowed interviewers to use more open‐ended questions and to obtain more details. The results show that providing feedback significantly increased the quality of the interviews. It is recommended that the NICHD protocol be used to interview child victims and witnesses and that feedback sessions be held with interviewers. Copyright © 2012 John Wiley & Sons, Ltd.     

Beyond the Polemics: Freedom and Necessity in Plotinus and St Maximus Confessor

Abstract: The aim of this paper is to challenge the prevailing polemic between ‘necessary’ emanation and ‘free’ creation. I begin by arguing for the presence of freedom and volition in the emanationism of Plotinus. I then move on to explore the role of necessity in the creationism of Maximus. In both cases, I rely upon a twofold schematisation of freedom and necessity to dissolve the dichotomy between them effectively. Having levelled the playing field, so to speak, I conclude that, all things being equal, one does find in Maximus (and Christian thinkers generally) a heightened sense of divine volition and relationality beyond that of the pagan Neoplatonists. This greater emphasis upon the freedom of the divine will, however, has little bearing on whether Maximus's doctrine of creation is ‘emanationist’ or ‘creationist’. Instead, it stems from a biblically inspired sense of the One God as intimately involved in His creation which, though derived from God, is crucially other than God.     

Does adolescent heavier alcohol use predict young adult aggression and delinquency? Parallel analyses from four Australasian cohort studies

While the association between heavy alcohol consumption and aggression has been well documented, the causal direction of this association, particularly at a population level, is disputed. A number of causal sequences have been proposed. First, that aggression leads to heavy alcohol use. Second, that heavy alcohol use leads to aggression. Third, that the association between alcohol use and aggression is due to confounding by (a) sociodemographic variables or (b) delinquency. We report here data from four Australasian prospective longitudinal studies of adolescents, to assess the temporal sequence of heavy drinking and aggression over the period from adolescence to young adulthood. The four cohort studies provide a total sample of 6,706 persons (Australian Temperament Project, n = 1701; Christchurch Health and Development Study, n = 931; Mater-University of Queensland Study of Pregnancy, n = 2437; Victorian Adolescent Health Cohort Study, n = 1637). We use multinomial logistic regression to determine whether early adolescent aggression predicts subsequent age of onset of heavy episodic drinking (HED), after adjustment for concurrent sociodemographic factors and delinquency. We then consider whether HED predicts subsequent aggression, after adjusting for past aggression, concurrent delinquency, and a range of confounders. There are broadly consistent findings across the four cohort studies. Early aggression strongly predicts subsequent HED. HED predicts later aggression after adjustment for prior aggression and other confounders. Policies that alter population levels of alcohol consumption are likely to impact on levels of aggression in societies where HED linked to aggression is more common.     

Describing and Measuring the Pathway to Suicide Attempts: A Preliminary Study

To die by suicide, one must think about suicide, make a plan, and then carry it out. Prior research has examined the presence and predictors of these outcomes; however, virtually no studies have characterized how these steps unfold along the pathway to suicide. A novel instrument was administered to 30 recent suicide attempters. Results revealed that although the median onset for suicidal ideation occurs 1 to 5 years prior to attempting, the median for 6 of the 10 steps measured was within 6 hours of attempting. Overall, 86.5% of proximal planning steps took place within 1 week of attempting and 66.6% occurred within 12 hours.     

Is A Person Thinking About Suicide Likely to Find Help on the Internet? An Evaluation of Google Search Results

It is unclear whether individuals searching the Internet for assistance with thoughts of suicide are likely to encounter predominantly helpful or harmful resources. This study investigated websites retrieved by searching Google for information and support for suicidal thoughts. Google searches retrieved a high percentage of irrelevant websites (26%, n = 136). Of the 329 relevant websites retrieved, the majority were suicide preventive (68%); however, a considerable proportion of sites expressed mixed (22%) or neutral (8%) suicide attitudes, and 1% were explicitly pro‐suicide. The results highlight a need for suicide prevention organization websites to be made more easily accessible. In the meantime, clinicians should be aware of appropriate websites to recommend to clients.     

The Role of Sleep Disturbance in Suicidal and Nonsuicidal Self‐Injurious Behavior among Adolescents

The relationship between different sleep disturbances and self‐harm thoughts and behaviors was examined among 223 adolescents presenting to a community clinic for mood disorders and suicidal and nonsuicidal self‐injurious behaviors. Two‐thirds of the adolescents reported nightly, severe sleep complaints. Relative to adolescents without significant sleep complaints, patients with severe sleep complaints at the time of clinic entry endorsed significantly more engagement in nonsuicidal self‐injury. Middle insomnia and circadian reversal were both significant predictors of suicide attempts. Terminal insomnia was significantly associated with suicidal ideation. Results support the importance of assessing sleep difficulties among adolescents at risk for suicide.
