Cognitive-behaviour therapy for depersonalisation disorder: an open study

Depersonalisation (DP) and derealisation (DR) are subjective experiences of unreality in, respectively, one's sense of self and the outside world. These experiences occur on a continuum from transient episodes that are frequently reported in healthy individuals to a chronic psychiatric disorder that causes considerable distress (depersonalisation disorder: DPD). Despite the relatively high rates of reporting these symptoms, little research has been conducted into psychological treatments for this disorder. We report on an open study where 21 patients with DPD were treated individually with cognitive behavioural therapy (CBT). The therapy involved helping the patients re-interpret their symptoms in a non-threatening way as well as reducing avoidances, safety behaviours and symptom monitoring. Significant improvements in patient-defined measures of DP/DR severity as well as standardised measures of dissociation, depression, anxiety and general functioning were found at post-treatment and six-months follow-up. Moreover, there were significant reductions in clinician ratings on the Present State Examination (Wing, Cooper & Sartorius, 1974), and 29% of participants no longer met criteria for DPD at the end of therapy. These initial results suggest that a CBT approach to DPD may be effective, but further trials with larger sample sizes and more rigorous research methodology are needed to determine the specificity of this approach.     

Infant Directed Speech in Natural Interaction—Norwegian Vowel Quantity and Quality

An interactive face-to-face setting is used to study natural infant directed speech (IDS) compared to adult directed speech (ADS). With distinctive vowel quantity and vowel quality, Norwegian IDS was used in a natural quasi-experimental design. Six Norwegian mothers were recorded over a period of 6 months alone with their infants and in an adult conversation. Vowel duration and spectral attributes of the vowels /a:/, /i:/ and /u:/, and their short counterparts /a/ /i/ and /u/ were analysed. Repeated measures analyses show that effects of vowel quantity did not differ between ADS and IDS, and for back vowel qualities, the vowel space was shifted upwards in IDS compared to ADS suggesting that fronted articulations in natural IDS may visually enhance speech to infants.     

A portable,unobtrusive device for videorecording clinical interactions

Recording and analyzing real-time interactions in clinical settings is important for basic and applied research in psychology and other disciplines. Investigators frequently have used simple audiotaping procedures to record these encounters (e.g., Roter, Geller, Bernhardt, Larson, & Doksum, 1999), but videorecording is increasingly viewed as more reliable and valid, because it captures the full range of complex and interdependent verbal and nonverbal behaviors that occur in an interaction. This article describes a system designed to videotape clinical interactions in a manner that can be moved in and out of different clinical rooms to preserve flexibility in its use. Data are presented to demonstrate that the system is unobtrusive during the interaction, yet fully compatible with institutional review board guidelines to protect human participants’ privacy and freedom to control the recording process.     

How similar is similar enough? Job profile similarity benchmarks using occupational information network data

Job comparison research is critical to many human resources initiatives, such as transporting validity evidence. Job analysis methods often focus on critical attribute (e.g., tasks, work behaviors) overlap when assessing similarity, but profile similarity metrics represent an alternative or complementary approach for job comparisons. This paper utilizes Occupational Information Network (O*NET) data to establish a distribution of job profile correlations across all job pairs for five attributes – generalized work activities, knowledge, skills, abilities, and work styles. These correlations represent effect sizes, or degree of shared variance between jobs. Practitioners may reference these correlational distributions as benchmarks for gauging the practical significance of the observed degree of similarity between two jobs of interest compared to the broader world of work.     

Courseware for observational research (COR): A new approach to teaching naturalistic observation

Naturalistic observation is one of the most basic and widely used techniques of scientific research, yet it often receives only a cursory treatment in the research methods course. In this paper, we describe a new interactive multimedia software program that teaches interval, frequency, and duration coding with the use of brief digitized video clips and model check sheets. The program teaches basic observational techniques by leading students through the stages of developing a behavioral coding scheme, collecting data, establishing interrater reliability, and analyzing with chi square. It also has a laboratory component that allows students to practice their skills.     

Effects of Contract Framing,Motivation to Quit,and Self-Efficacy on Smoking Reduction1

Social learning theorists (SLT) have advocated that individual's cognitive beliefs about perceived behavioral ability and outcome expectancies are predictive of behavior change. SLT's also propose that the threat of losing positive rewards may result in greater behavior change than gaining rewards for altering behaviors such as smoking. Specifically, presenting behavioral outcomes in a loss frame context has proven more influential under certain conditions than presenting outcomes in a gain frame context. The present study evaluated the relationship between smoking cessation self-efficacy motivation to quit, and contract framing on smoking reduction. The majority of cognitive and behavioral changes occurred between baseline and 3 months into a 12-month treatment program. An interaction between contract framing and motivation to quit suggested that, for subjects with low motivation, receiving combined (gain plus loss) frame contracts resulted in smoking fewer cigarettes posttreatment than receiving gain frame only contracts. An interaction between framing and self-efficacy also indicated that subjects who received combined frame contracts smoked fewer cigarettes if they had high rather than low self-efficacy beliefs.     

The control of posture in newly standing infants is task dependent

The postural sway patterns of newly standing infants were compared under two conditions: standing while holding a toy and standing while not holding a toy. Infants exhibited a lower magnitude of postural sway and more complex sway patterns when holding the toy. These changes suggest that infants adapt postural sway in a manner that facilitates visually fixating on and stabilizing the toy in their hand. When simply standing, infants exhibited postural sway patterns that appeared to be more exploratory in nature. Exploratory sway patterns may allow infants to learn the affordances of their new standing posture. These results demonstrate that newly standing infants are capable of task-dependent postural control.     

Processing Differences between Feature‐Based Facial Composites and Photos of Real Faces

Computer‐generated faces (composites) constructed by select2ing individual facial features (e.g. eyes, nose, mouth) are poorly recognized because this process contrasts with the natural holistic processing of real faces. This result suggests that there should be differences in the cognitive processing of these composites compared with photos of real faces, which would make these stimuli problematic for theories seeking to explain real face processing. We conducted five experiments to test potential conditions for moving composite processing closer to how real face photos are processed, first taking the perspective of researchers who construct composites with a random selection of available features and then taking a perspective closer to police by creating each composite to match a real face photo. Composites with randomly selected features (but configured like real faces) showed no face inversion effect and recognition memory for these composites benefited from increased encoding time, unlike real face photos. Although composites constructed to match real face photos yielded an inversion effect, they still were remembered differently than the photos. Researchers should not use feature‐based composites as proxies for real face photos. We conclude with a discussion of alternative methods of constructing composites.

The Effectiveness of an Explicit Instruction Writing Program for Second Graders

The National Assessment of Educational Progress found that only 25% of 4th, 8th, and 12th grade students were at grade-level writing proficiency (Greenwald et al. 1999). Insufficient writing skill is a major contributor to lack of school and college success. The current study evaluated a modification of Quickwrite (Maloney 1998), a strategic writing program that explicitly teaches students how to brainstorm, plan, draft, and revise within brief time periods. Teachers who did not have knowledge of the study or the participants rated the overall number of story elements included in second-grade students’ stories higher after the intervention. The rate of student writing did not improve. Results were maintained 4 weeks after the intervention.
