Childhood Psychological Trauma and First‐Year College Students' Substance Dependence

First‐year college students (N= 143) completed the Substance Abuse Subtle Screening Inventory‐3 and a questionnaire about childhood traumatic experiences. As the number of traumatic experiences increases, so does the likelihood of substance use in college.     

Improving the Generalization of Computer-Based Math Fluency Building Through the Use of Sufficient Stimulus Exemplars

Computers have become an important piece of technology in classrooms for implementing academic interventions. Often, students’ responses to these interventions are used to help make important educational decisions. Therefore, it is important to consider the effect of these interventions across multiple contexts. For example, previous research has demonstrated that when students practice math fact fluency on the computers gains did not generalize to paper–pencil performance. The current study extended this research by examining the effect of multiple stimulus exemplars on the generalization of computer-based math practice to paper–pencil performance. A total of 57 second-grade students completed fluency drills only on the computer, computer mixed with paper–pencil or with only paper–pencil. Pretest–posttest performance was evaluated using a 3 × 2 doubly multivariate repeated-measures ANOVA, with follow-up univariate analysis to determine whether the interaction between time and treatment type was similar across matched and unmatched treatment modalities. Results from previous research were replicated with a lack of generalization across modalities, but the addition of multiple stimulus exemplars resulted in increased generalization for those students receiving a mix of computer and paper–pencil practice.     

Poor Imitative Performance of Unlearned Gestures in Children with Probable Developmental Coordination Disorder

It has been hypothesized that deficits in imitation, linked to abnormal functioning of the mirror neuron system (MNS), may contribute to the motor impairments associated with developmental coordination disorder (DCD). The authors aimed to examine imitation of complex novel postures and sequences of gestures in children with and without probable DCD (pDCD), using the postural praxis and sequencing praxis subtests of the Sensory Integration and Praxis Tests (Ayres, 1989 Ayres, A. J. (1989). Sensory Integration and Praxis Tests: SIPT manual. Los Angeles, CA: Western Psychological Services. [Google Scholar]). Participants were 29 boys with pDCD between 6.08 and 13.33 years old, and 29 group age-matched typically developing boys between 6.08 and 13.83 years old. Responses of children with pDCD on both imitation tasks were less accurate than controls, with group differences more apparent with increasing task complexity. Furthermore, as a group, children with pDCD were slower and had a higher number of non–mirror-imitated responses. There was considerable variability within the pDCD group, with some children displaying imitation scores within the normative range. Given the importance of imitation and visual learning for motor development, the difficulties in imitation displayed by some children with pDCD have the potential to impact on movement acquisition. Interventions to target imitation may be beneficial for these children. The results show that children with pDCD had difficulty imitating complex novel postures, children with pDCD had difficulty imitating gesture sequences, children with pDCD had slower responses than controls, group differences in imitation performance increased with task complexity, and not all children with pDCD displayed imitation deficits.     

Objectification leads to depersonalization: The denial of mind and moral concern to objectified others

Philosophers have argued that when people are objectified they are treated as if they lack the mental states and moral status associated with personhood. These aspects of objectification have been neglected by psychologists. This research investigates the role of depersonalization in objectification. In Study 1, objectified women were attributed less mind and were accorded lesser moral status than non‐objectified women. In Study 2, we replicated this effect with male and female targets and extended it to include perceptions of competence and pain attribution. Further, we explored whether target and perceiver gender qualify depersonalization. Overall, this research indicates that when people are objectified they are denied personhood.

Scoring the DSM-IV personality disorders using the Five-Factor Model: development and validation of normative scores for North American, French, and Dutch-Flemish samples

Five-Factor Model (FFM) personality disorder (PD) counts have demonstrated significant convergent and discriminant validity with DSM-IV PD symptoms. However, these FFM PD counts are of limited clinical use without normative data because it is difficult to determine what a specific score means with regard to the relative level of elevation. The current study presents data from three large normative samples that can be used as norms for the FFM PD counts in the respective countries: United States (N = 1,000), France (N = 801), and Belgium-Netherlands (N = 549). The present study also examines the performance, with regard to diagnostic efficiency, of statistically-defined cut-offs at 1.5 standard deviations above the mean (T > or = 65) versus previously identified cut-offs using receiver-operator characteristics (ROC) analyses. These cut-offs are tested in three clinical samples-one from each of the aforementioned countries. In general, the T > or = 65 cut-offs performed similarly to those identified using ROC analyses and manifested properties relevant to a screening instrument. These normative data allow FFM data to be used in a flexible and comprehensive manner, which may include scoring this type of personality data in order to screen for DSM-IV PD constructs.     

Social identity, status characteristics and social networks: Predictors of advice seeking in a manufacturing facility

In the sociological tradition, status characteristics and patterns of interpersonal relations within a social network are considered important in explaining organizational behaviour (e.g. influence, cooperation). In the social identity tradition, perceptions of shared psychological group membership and group prototypicality are considered important in explaining many of the same organizational behaviours. The present paper explores core variables within each of these perspectives as predictors of advice seeking among supervisors in a manufacturing facility. Dyadic measures of group assignment are found to better predict advice seeking than measures taken at the individual level. Identification with work groups predicted advice seeking from those perceived to be in the same group, and also from structural equivalents. Implications for theory and further research are discussed.
