Criteria‐based content analysis of true and suggested accounts of events

Worldwide, the criteria‐based content analysis (CBCA) is probably the most widely used veracity assessment technique for discriminating between accounts of true and fabricated events. In this study, two experiments examined the effectiveness of the CBCA for discriminating between accounts of true events and suggested events believed to be true. In Experiment 1, CBCA‐trained judges evaluated participants' accounts of true and suggestively planted childhood events. In Experiment 2, judges analysed accounts of recent events that were experimentally manipulated to be a (a) true experience, (b) false experience believed to be true and (c) deliberately fabricated experience. In both experiments CBCA scores were significantly higher for accounts of true events than suggested events. However, this difference was not significant for participants classified as experiencing ‘full’ memories for the suggested event. Self‐report memory measures supported the findings of the CBCA analyses. Taken together these results suggest that the CBCA discriminative power is greatly constrained.

Social Interaction During Computer-based Activities: Comparisons by Number of Sessions, Gender, School-level, Gender Composition of the Group, and Computer-child Ratio

This study assessed the quality of social interactions that occur in group-based computer learning contexts. Gender comparisons of interactions were examined across 3 sessions with 116 preschoolers (M age?=?4.9 years) and 108 fifth and sixth-grade (M age?=?11.7 years) Canadian children from southwestern Ontario, when children had access to one computer per child (parallel computer) or one computer per group (integrated computer), and when they worked with same-gender or mixed-gender peers. Preschoolers engaged in more collaborative behaviors in mixed-gender than same-gender groups, while elementary children engaged in collaborative behaviors more often in integrated than parallel computer conditions. In mixed-gender groups, boys were more likely than girls to dominate the computer in elementary school while girls were more likely than boys to dominate the computer in preschool.     

Assessing ADHD-related Family Stressors with the Disruptive Behavior Stress Inventory (DBSI): A Replication and Extension

The Disruptive Behavior Stress Inventory (DBSI) was developed to provide information related to the occurrence and severity of stressors that result from having a child with ADHD. Data provided in the initial 2002 study by Johnson and Reader (Journal of Clinical Psychology in Medical Settings, 9, 51–62) provided good preliminary support for the reliability of the DBSI, as well the ability of the scale scores to differentiate primary caregivers of children with and without a history of ADHD. The present study was an attempt to replicate major findings of the 2002 study using an additional larger sample and extend it by conducting item-level analyses to determine the degree to which individual DBSI items differentiate primary caregivers of children with and without a history of ADHD. Results provided additional support for the reliability and validity of the DBSI by replicating major findings from the 2002 study and further suggesting that a large majority of the 40 items individually differentiate between primary caregivers of children with and without a history of ADHD.     

Axiomatic Quantum Theory

The basis of a rigorous formal axiomatization of quantum mechanics is constructed, built upon Dirac's bra–ket notation. The system is three-sorted, with separate variables for scalars, vectors and operators. First-order quantification over all three types of variable is permitted. Economy in the axioms is effected by, e.g., assigning a single logical function * to transform (i) a scalar into its complex conjugate, (ii) a ket vector into a bra and a bra into a ket, (iii) an operator into its adjoint. The system is accompanied by a formal semantics. Further papers will deal with vector subspaces and projection operators, operators with continuous spectra, tensor products, observables, and quantum mechanical probabilities.     

Carding for the Purchase of Alcohol: I'm Tougher Than Other Clerks Are1

The present research examined whether clerks believed themselves to be more likely to card customers than “other” clerks. Store clerks (N= 121) from 23 stores of a major grocery chain rated 4 person‐product profiles of hypothetical shoppers each representing distinctive lifestyle groups. Embedded within a series of items were key questions that asked how likely it was that they and other clerks would ask for identification from the shopper for the purchase of alcohol. Across all conditions, data revealed a significant positivity bias suggesting that the clerks felt that they were much better than other clerks at determining who should be asked for identification. The data are discussed in terms of their motivational implications for the false uniqueness bias.     

Relational frame theory,acceptance and commitment therapy,and a functional analytic definition of mindfulness

The present article interprets mindfulness from the point of view of the effects of language and cognition on human action. Relational Frame Theory is described to show how human suffering is created by entanglement with the cognitive networks made possible by language. Mindfulness can be understood as a collection of related processes that function to undermine the dominance of verbal networks, especially involving temporal and evaluative relations. These processes include acceptance, defusion, contact with the present moment, and the transcendent sense of self. Each of these components of mindfulness are targeted in Acceptance and Commitment Therapy, and there is some evidence that they underlie the therapeutic changes induced by this approach. The relation between the present approach to mindfulness and other approaches is discussed.     

Effectiveness of a Group Therapy Program for Children with Psychosocial Deficits: Benefits of Concurrent Participation in Organized Activities

Prior research suggests children’s involvement in organized activities predicts positive outcomes, although benefits for youth with psychosocial deficits remain unclear. This study examines if activity participation predicts response to a group therapy program for children with psychosocial deficits and if improvements depend on children’s functioning within the organized activity context. Participants were 178 children (M age?=?9.6 years) enrolled in a group therapy program. Greater activity participation significantly predicted improvements in family functioning and social skills, suggesting the value of participation in organized activities for youth with psychosocial deficits.
