Negative Thought

Testing a variant of Wegner's (1989) “thought suppression” paradigm, we had subjects identify a personally-relevant negative thought that had been troubling them recently. Subjects were then randomly assigned either to a negative target thought group or to a neutral target thought (“white bear”) group, and randomly assigned either to an initial suppression condition (followed by a free expression period) or an initial free expression condition (followed by a suppression period). The results revealed that subjects in the neutral thought group experienced a decline in thoughts about white bears throughout the course of the experiment, whereas subjects asked first to suppress a personally relevant negative thought experienced nearly a three-fold increase in its frequency of occurrence when later given permission to express it. These findings suggest that negatively valent thoughts may respond differently than neutral thoughts following attempts to suppress them.

High and low defensive individuals engaged in attempted thought suppression and non‐suppression after viewing an emotionally stressful piece of film. As a function of suppression and non‐suppression instructions, high and low defensive individuals differed from each other in the number of reported film‐related thoughts. Suppression instructions had greatest effects on low defensive individuals in reducing the number of reported film‐related thoughts. The effects of suppression instructions were not significant in reducing the number of film‐related thoughts for high defensive individuals. High defensive individuals also reported more neutral thoughts under the suppression condition compared with the non‐suppression condition. Low defensive individuals reported similar numbers of neutral thoughts under the two conditions. Effects of suppression instructions were investigated in a subsequent cognitive task that measured the level of interference produced by attempted suppression. Suppression instructions did not significantly effect the cognitive processing of participants. Theoretical and methodological implications for understanding the possible cognitive structures underlying attempted suppression are discussed in terms of the effects of defensiveness.

AirfugeR (Beckman) direct ultracentrifugation of viral samples on electron microscopy grids offers a rapid way to concentrate viral particles or subunits and facilitate their detection and study. Using the A-100 fixed angle rotor (30°) with a K factor of 19 at maximum speed (95 000 rpm), samples up to 240 μl can be prepared for electron microscopy observation in a few minutes: observation time is decreased and structural details are highlighted. Using latex spheres to calculate the increase in sensitivity compared to the inverted drop procedure, we obtained a 10 to 40 fold increase in sensitivity depending on the size of particles. This technique also permits quantification of viral particles in samples if an aliquot is mixed with latex spheres of known concentration.Direct ultracentrifugation for electron microscopy can be performed on laboratory samples such as gradient or column fractions, infected cell supernatant, or on clinical samples such as urine, tears, cephalo-rachidian liquid, etc..

Pair Analysis

The eye-brain complex allows those of us with normal vision to perceive and evaluate our surroundings in three-dimensions (3-D). The principle factor that makes this possible is parallax - the horizontal displacement of objects that results from the independent views that the left and right eyes detect and simultaneously transmit to the brain for superimposition. The common SEM micrograph is a 2-D representation of a 3-D specimen. Depriving the brain of the 3-D view can lead to erroneous conclusions about the relative sizes, positions and convergence of structures within a specimen. In addition, Walter has suggested that the stereo image contains information equivalent to a two-fold increase in magnification over that found in a 2-D image. Because of these factors, stereo pair analysis should be routinely employed when studying specimens.Imaging complementary faces of a fractured specimen is a second method by which the topography of a specimen can be more accurately evaluated.

Tweed Structure

Natural Amelia albite (Ab99.3An0.1Or0.6) annealed at 1073° and 924°C for various periods up to 140 days has been studied by NMR. TEM studies of the same sample revealed a distinct tweed microstructure in some samples annealed at both 1073°C and 924°C. On the whole, the quasi-regular tweed has a periodicity of 100 - 200 Å in both directions, one nearly normal to b* and the other approximately parallel to b*, which gives rise to two-directional streaking in SADP’s (Fig. 1 and 2). However, there are some differences in the tweed structure developed on annealing at 1073°C and at 924°C in albite.Albite samples annealed at 1073° show a systematic trend in their development of tweed structures: the regularity, periodicity, and frequency of occurrence increase with annealing time during the first 3 days, and then decrease gradually until no tweed microstructures are seen in samples annealed for more than 15 days. The tweed structure proceeds locally to form one-directional twin-like microstructures.

This study examines the assumptions underlying the scoring system of the Arizona Articulation Proficiency Scale: Revised. Twenty-one children between the ages of four years two months and six years 11 months were administered the Arizona Articulation Proficiency Scale: Revised and the Screening Deep Test of Articulation. The subjects' performance on the two tests was compared for the phones: [s], [l], [r], [t∫], [θ], [∫], [k], [f], and [t]. Results suggested that 1) the production of most sounds in only two contexts does not necessarily reflect the accuracy of production of those sounds in other contexts, and 2) for the sounds tested, the weightings assigned on the basis of their frequency of occurrence rather than the frequency with which they were misarticulated overestimated the extent of many articulation errors.

Classroom teachers were asked to list the traits they felt were characteristic of the elementary school child who wears a hearing aid. These listings were evaluated according to the desirability of the traits and were studied regarding frequency of occurrence, desirability, and educational, emotional, and social implications. The results of the groupings are discussed in terms of pre-service and in-service training.

Mental Health Distress

Purpose The aim of this study was to examine the relationship between tinnitus and self-reported mental health distress, namely, depression symptoms and perceived anxiety, in adults who participated in the National Health and Nutrition Examinations Survey between 2009 and 2012. A secondary aim was to determine if a history of serving in the military modified the associations between tinnitus and mental health distress. Method This was a cross-sectional study design of a national data set that included 5,550 U.S. community-dwelling adults ages 20 years and older, 12.7% of whom were military Veterans. Bivariable and multivariable logistic regression was used to estimate the association between tinnitus and mental health distress. All measures were based on self-report. Tinnitus and perceived anxiety were each assessed using a single question. Depression symptoms were assessed using the Patient Health Questionnaire, a validated questionnaire. Multivariable regression models were adjusted for key demographic and health factors, including self-reported hearing ability. Results Prevalence of tinnitus was 15%. Compared to adults without tinnitus, adults with tinnitus had a 1.8-fold increase in depression symptoms and a 1.5-fold increase in perceived anxiety after adjusting for potential confounders. Military Veteran status did not modify these observed associations. Conclusions Findings revealed an association between tinnitus and both depression symptoms and perceived anxiety, independent of potential confounders, among both Veterans and non-Veterans. These results suggest, on a population level, that individuals with tinnitus have a greater burden of perceived mental health distress and may benefit from interdisciplinary health care, self-help, and community-based interventions.

Severe Anxiety

Obsessive-compulsive disorder (OCD) is a severe anxiety disorder characterized by frequent obsessive thoughts and repetitive behaviors. Neuroticism is a vulnerability factor for OCD, yet the mechanisms by which this general vulnerability factor affects the development of OCD-related symptoms are unknown. The present study assessed a hierarchical model of the development of obsessive thoughts that includes neuroticism as a general, higher-order factor, and specific, potentially maladaptive thought processes (thought suppression, worry, and brooding) as second-order factors manifesting in the tendency toward obsessing. A total of 238 participants completed questionnaires assessing the examined constructs. The results of mediator analyses demonstrated the hypothesized relationships: A positive association between neuroticism and obsessing was mediated by thought suppression, worry, and brooding. Independent of the participant’s sex, all three mediators contributed equally and substantially to the association between neuroticism and obsessing. These findings extend earlier research on hierarchical models of anxiety and provide a basis for further refinement of models of the development of obsessive thoughts.

The Impact

This study investigates the impact of thought suppression over a 1-week interval. In two experiments with 80 university students each, we used the think/no-think paradigm in which participants initially learn a list of word pairs (cue-target associations). Then they were presented with some of the cue words again and should either respond with the target word or avoid thinking about it. In the final test phase, their memory for the initially learned cue-target pairs was tested. In Experiment 1, type of memory test was manipulated (i.e., direct vs. indirect). In Experiment 2, type of no-think instructions was manipulated (i.e., suppress vs. substitute). Overall, our results showed poorer memory for no-think and control items compared to think items across all experiments and conditions. Critically, however, more no-think than control items were remembered after the 1-week interval in the direct, but not in the indirect test (Experiment 1) and with thought suppression, but not thought substitution instructions (Experiment 2). We suggest that during thought suppression a brief reactivation of the learned association may lead to reconsolidation of the memory trace and hence to better retrieval of suppressed than control items in the long term.
