The reliability of eyetracking to assess attentional bias to threatening words in healthy individuals

Eyetracking is commonly used to investigate attentional bias. Although some studies have investigated the internal consistency of eyetracking, data are scarce on the test–retest reliability and agreement of eyetracking to investigate attentional bias. This study reports the test–retest reliability, measurement error, and internal consistency of 12 commonly used outcome measures thought to reflect the different components of attentional bias: overall attention, early attention, and late attention. Healthy participants completed a preferential-looking eyetracking task that involved the presentation of threatening (sensory words, general threat words, and affective words) and nonthreatening words. We used intraclass correlation coefficients (ICCs) to measure test–retest reliability (ICC > .70 indicates adequate reliability). The ICCs(2, 1) ranged from –.31 to .71. Reliability varied according to the outcome measure and threat word category. Sensory words had a lower mean ICC (.08) than either affective words (.32) or general threat words (.29). A longer exposure time was associated with higher test–retest reliability. All of the outcome measures, except second-run dwell time, demonstrated low measurement error (<6%). Most of the outcome measures reported high internal consistency (α > .93). Recommendations are discussed for improving the reliability of eyetracking tasks in future research.     

Exploratory Evaluation and Initial Adaptation of a Parent Training Program for Hispanic Families of Children with Autism

The present paper takes a translational approach in applying the themes of the current special section to prevention and intervention science in Latino families. The paper reviews the current literature on cultural processes in prevention and intervention research with Latino families. Overall, many prevention and intervention programs have either been developed specifically for Latino families or have been modified for Latino families with great attention paid to the socio‐cultural needs of these families. Nevertheless, few studies have tested the role of cultural values or acculturation processes on outcomes. We make recommendations based on findings within basic science and in particular this special section on the incorporation of these values and processes into prevention and intervention science with Latino families.     

Eliciting positive,negative and mixed emotional states: A film library for affective scientists

We describe the creation of a film library designed for researchers interested in positive (amusing), negative (repulsive), mixed (amusing and repulsive) and neutral emotional states. Three hundred 20- to 33-second film clips videotaped by amateurs were selected from video-hosting websites and screened in laboratory studies by 75 female participants on self-reported amusement and repulsion (Experiments 1 and 2). On the basis of pre-defined cut-off values, 51 positive, 39 negative, 59 mixed and 50 neutral film clips were selected. These film clips were then presented to 411 male and female participants in a large online study to identify film clips that reliably induced the target emotions (Experiment 3). Depending on the goal of the study, researchers may choose positive, negative, mixed or neutral emotional film clips on the basis of Experiments 1 and 2 or Experiment 3 ratings.     

An investigation of factors influencing accountability and performance ratings

The authors explored whether accountability has implications for performance ratings and investigated factors that may influence both accountability and performance ratings. Specifically, they investigated (a) whether feelings of accountability are directly related to performance ratings, (b) whether experimental manipulations that have been proposed to manipulate accountability in fact do so, and (c) the role of motivation-related constructs. They developed and tested a model of factors proposed to influence accountability and performance ratings. Results from 334 raters in an upward feedback situation in a classroom context provide empirical support that feelings of accountability influence rating level, as do perceptions of anonymity and the importance raters place on their jobs. However, neither anonymity nor importance perceptions were related to feelings of accountability.     

Matching illumination of solid objects

The appearance of objects is determined by their surface reflectance and roughness and by the light field. Conversely, human observers might derive properties of the light field from the appearance of objects. The inverse problem has no unique solution, so perceptual interactions between reflectance, roughness, and lightfield are to be expected. In two separate experiments, we tested whether observers are able to match the illumination of spheres under collimated illumination only (matching of illumination direction) and under more or less diffuse illumination (matching of illumination direction and directedness of the beam). We found that observers are quite able to match collimated illumination directions of two rendered Lambertian spheres. Matching of the collimated beam directions of a Lambertian sphere and that of a real object with arbitrary reflectance and roughness properties resulted in similar results for the azimuthal angle, but in higher variance for the polar angle. Translucent objects and a tennis ball were found to be systematic outliers. If the directedness of the beam was also varied, the direction settings showed larger variance for more diffuse illumination. The directedness settings showed an overall quite large variance and, interestingly, interacted with the polar angle settings. We discuss possible photometrical mechanisms behind these effects.     

Shape effects on memory for location

The participants were 40 students who were briefly presented 32 dot locations, one at a time, and attempted to reproduce each location after a short delay. Half of the participants completed the task with the surrounding shapes being a circle, a horizontal ellipse, and a vertical ellipse; for the other half, the surrounding shapes were a square, a triangle, and a pentagon. Elongation of the task field along an axis led to exaggerated bias along that axis, but the pattern of bias was fairly constant across the shapes. The data were modeled by assuming that bias in estimation was due to the weighting of spatial category prototypes. Modeling indicated that shape affected spacing of prototypes, but there was no evidence that it affected the number of prototypes. These results were consistent with use of a viewer-based frame of reference, with prototypes reflecting four spatial quadrants generated by left—right and up—down distinctions from the viewer’s perspective.     

Letters of Recommendation: Controversy and consensus from expert perspectives

Letters of recommendation (LORs) are a widely used selection tool with many issues associated with their use. To address some of these issues, 575 professionals in personnel‐related professions reported their experiences with LORs. We separated items into consensus, polarized, or neither categories. Experts reached consensus that letter inflation is a problem that may never be alleviated and that more weight is placed on letters written by someone the reader knows or from a prestigious institution or organization. Most items were polarized, suggesting substantial controversy in the field regarding LORs. Some items originally polarized reached consensus within profession (academic vs applied). Academic professionals reported using LORs more and placing more weight on their contents than applied professionals. Implications discussed include recommendations for future research and practice, such as the appropriate use of LORs, LOR formats, and training.     

Best Practices for Counselors Who Treat Posttraumatic Stress Disorder

Counselors in settings as diverse as schools, corporations, and community agencies are well aware of the numbers of people in the United States who daily come in contact with stressors that are extreme and potentially traumatic. Automobile accidents, disasters, or encounters with interpersonal violence are ubiquitous. Professional counselors, regardless of their professional identification or the settings in which they work, are very likely providing services to many people who are in distress after traumatic exposures. These counselors would benefit from knowing what other mental health professionals consider to be best practices for preventing and treating posttraumatic stress disorders (PTSDs). The purpose of this article is to summarize for counselors those best practices that have been recently developed and published by a multidisciplinary expert group (E. B. Foa, J. R. T. Davidson, & A. Frances, 1999) in their article “Treatment of Posttraumatic Stress Disorder.”     

Absolute vs Relative Performance Rating Formats: Implications for fairness and organizational justice

The choice of performance rating format may influence employees' fairness perceptions. Participants in two studies, one consisting of 208 participants and the other of 393 participants, evaluated the fairness of common relative and absolute rating formats. The participants in the second study also evaluated the fairness of two rating formats, one absolute and one relative, presented in organizational contexts of varying procedural and distributive justice. Results indicate that not only are absolute formats perceived as more fair than relative formats, but differences in fairness perceptions also occur among relative and absolute formats. Furthermore, it appears that rating format influences procedural justice, especially when outcomes are perceived as fair. Implications for organizations' appraisal practices are discussed.
