Cognitive Influences on the Perception of Somatic Change During a Feigned Chemical Release1

The role of psychological processes in the perception of bodily symptoms was investigated during a feigned chemical release. Somatic change was manipulated through exercise, while chemical pollutant cues were used to provide explanatory frameworks for illness perceptions. Experimental participants were informed that they would be exposed to a common urban chemical pollutant while they exercised or rested in an atmosphere‐controlled chamber. In actuality, no pollutant was released. Control participants were informed correctly that they would be exposed only to room air in the chamber. Results showed that the presence of a chemical cue resulted in more attributions of symptoms to a chemical cause, in addition to the report of a greater number of symptoms. However, only during states of arousal induced by the exercise did the chemical cue have an effect on symptom intensity reporting. Participants who exercised in the context of salient chemical pollutant cues reported heightened levels of chemical‐exposure‐type symptoms (e.g., dizziness, dry throat) as compared to control participants and participants whose exercise arousal had diminished. Findings show that individuals will use a chemical explanatory framework for symptoms when conditions suggest toxic exposure, and that adoption of these explanatory frameworks modifies the experience of somatic change.     

In the Midst of a Hurricane: A Case Study of a Couple Living With AIDS

This case study provides insight into 1 heterosexual couple's experience with AIDS. Through a series of interviews, the authors examined the experiences of a husband in the advanced stages of AIDS and of his wife, the primary caregiver. A thematic analysis revealed 4 themes: the emotional impact of the diagnosis, changes in the couple's daily lives, needs for social support, and spiritual journeys. Recommendations are given for counselors working with persons with AIDS and their heterosexual partners.     

A Critical Analysis of Approaches to the Development of Preventive Interventions for Subcultural Groups

The ultimate success of preventive interventions relies on their ability to engage and influence the growing presence of subcultural groups. To encourage and guide the development of effective preventive intervention for subcultural groups, four approaches are described, illustrated, and critiqued with respect to their considerations of cultural fit, reach, efficacy and adoption. Those approaches are (a) the prevention research cycle, (b) cultural adaptations of evidence-based interventions, (c) investigator-initiated culturally-grounded approaches, and (d) community-initiated indigenous approaches. Special attention is given to recent advances in the specification of stages in the cultural adaptation of interventions. The paper closes with some conclusions and topics in need of greater attention.     

Word recognition reflects dimension-based statistical learning

Speech processing requires sensitivity to long-term regularities of the native language yet demands listeners to flexibly adapt to perturbations that arise from talker idiosyncrasies such as nonnative accent. The present experiments investigate whether listeners exhibit dimension-based statistical learning of correlations between acoustic dimensions defining perceptual space for a given speech segment. While engaged in a word recognition task guided by a perceptually unambiguous voice-onset time (VOT) acoustics to signal beer, pier, deer, or tear, listeners were exposed incidentally to an artificial "accent" deviating from English norms in its correlation of the pitch onset of the following vowel (F0) to VOT. Results across four experiments are indicative of rapid, dimension-based statistical learning; reliance on the F0 dimension in word recognition was rapidly down-weighted in response to the perturbation of the correlation between F0 and VOT dimensions. However, listeners did not simply mirror the short-term input statistics. Instead, response patterns were consistent with a lingering influence of sensitivity to the long-term regularities of English. This suggests that the very acoustic dimensions defining perceptual space are not fixed and, rather, are dynamically and rapidly adjusted to the idiosyncrasies of local experience, such as might arise from nonnative-accent, dialect, or dysarthria. The current findings extend demonstrations of "object-based" statistical learning across speech segments to include incidental, online statistical learning of regularities residing within a speech segment.     

Observing home-visit quality with the home visit rating scales: Introduction to the special section

Evidence-based home-visiting programs aim to address one of the most important challenges facing our species—setting the next generation on a healthy path of development that prepares them for a future that is simultaneously uncertain and promising. Diverse research literatures have pointed to practices to effectively meet this challenge and better achieve the unfulfilled promise of home visiting by more effectively engaging parents in supporting their children's early development and well-being. Measures of home-visit quality practices drawn from social work, pediatric nursing, early childhood, and early intervention research literatures have identified building relationships with families and focusing on their strengths as effective, practices that are particularly important for vulnerable families. The articles in this special section used the Home Visit Rating Scales to examine stability in home-visit quality over time, study specific home-visiting processes linked with quality, validate a supervisor checklist of home-visiting implementation, and consider the home visit in relation to an array of indicators reflecting overall home-visiting program strength and stability. These articles exemplify progress in home-visiting research over recent decades, including advances in direct observational methods and measurement as well as examinations of home visiting as an observable process across various home-visiting program models and populations.     

Placing Age Differences in Cultural Context: A Comparison of the Effects of Age on PTSD After Disasters in the United States, Mexico, and Poland

Criterion symptoms of posttraumatic stress disorder (PTSD) were measured 6–12 months after Hurricane Andrew in the United States (non-Hispanic n = 270), Hurricane Paulina in Mexico (n = 200), and the 1997 flood in Poland (n = 285), using English, Spanish, and Polish versions of the Revised Civilian Mississippi Scale. The samples ranged in age from 18 to 88. Linear and quadratic effects of age were tested by using hierarchical multiple regression, with the effects of gender, trauma, and education controlled. Among Americans, age had a curvilinear relation with PTSD such that middle-aged respondents were most distressed. Among Mexicans, age had a linear and negative relation with PTSD such that younger people were most distressed. Among Poles, age had a linear and positive relation with PTSD such that older people were most distressed. Thus, there was no one consistent effect of age; rather, it depended upon the social, economic, cultural, and historical context of the disaster-stricken setting.     

Computer-assisted communication and team decision-making performance: the moderating effect of openness to experience

This study examined the effects of computer-assisted communication on team decision-making performance as a function of the team's openness to experience. Seventy-nine teams performing a multiple-cue probability learning task were randomly assigned to 1 of 2 experimental conditions: (a) verbal communication or (b) computer-assisted communication (which combined verbal and computerized communication). The results indicated that access to computer-assisted communication improved the decision-making performance of teams, but only when the teams were high in openness to experience. This effect was observed using both global openness and more specific openness facets, as well as a variety of team-level aggregation strategies. Moreover, the beneficial effects of openness in computer-assisted conditions were mediated by the efficiency with which teams integrated verbal and computerized forms of communication.     

Semantic category effect and emotional valence in female university students

The semantic category effect represents a category dissociation between biological and nonbiological objects in picture naming. The aim of this preliminary study was to further examine this phenomenon, and to explore the possible association between the effect and subjective emotional valence for the named objects. Using a speeded picture naming task, vocal reaction times for 45 items were divided into four categories based on emotional valence rating and semantic category, and examined in 36 female university students. Analyses of the data indicated an "animate/inanimate" category dissociation favouring animate objects, in tandem with a potential relationship between subjective emotional valence and semantic processing underlying picture naming.     

The Salient Stressor Impact Questionnaire (SSIQ): a measurement of the intensity and chronicity of stress

High stress is known to affect health, but stress impact, determined by events and responses to them, has not been studied systematically. For the Salient Stressor Impact Questionnaire (SSIQ), the impact of events was assumed to depend on their salience and chronicity and the impact of responses on their chronicity and intensity with greater unfavorable appraisal associated with greater response. The SSIQ assessed a person's two most salient stressors. Chronicity items discriminated between clinically stressed and nonclinical participants and measured the chronicity of stressful feelings (distress) and the event. The remaining items measured the degree of distress and unfavorable appraisal. The SSIQ showed good test-retest and internal consistency reliability, concurrent validity, and stability across diverse populations. Exploratory analyses grouped items into distress, chronicity, and appraisal elements, and confirmatory analysis revealed a good fit to the hypothesized model. Preliminary data suggest that the SSIQ will be useful for studying relationships between stress and health.     

Fundamentally misunderstanding visual perception. Adults' belief in visual emissions

The authors reviewed research about a profound misconception that is present among college students, namely, the belief that the process of vision includes emanations from the eyes, an idea that is consistent with the extramission theory of perception, which was originally professed by early Greek philosophers and which persisted in scholarly circles for centuries. The authors document the strength and breadth of this phenomenon and the object failure of traditional educational techniques to overcome this belief, and they reveal that students are leaving psychology courses with a flawed understanding of one of the most studied processes in the history of psychology--visual perception. Some suggestions are offered for overcoming this misconception in traditional college classroom settings.
