The effect of very brief exposure on experienced fear after in vivo exposure

Two experiments tested the effect of exposure to masked phobic stimuli at a very brief stimulus onset asynchrony on reducing the subjective experience of fear caused by in vivo exposure to a feared object. In the main experiment, 35 spider-fearful and 35 non-fearful participants were identified with a questionnaire and a Behavioural Avoidance Test (BAT) with a live tarantula. One week later, they were individually administered one of two continuous series of masked images: spiders or flowers. They engaged in the BAT again immediately thereafter. They provided ratings of subjective fear at the end of each BAT (pre- and post-manipulation). Very brief exposure to images of spiders reduced the fearful group's and not the non-fearful group's experience of fear at the end of the BAT. This effect was replicated with another sample of 26 spider-fearful participants from the same population. Theoretical implications are discussed.     

“Generic” and “Specific” Expertise in English: An Expert/Expert Study in Poetry Interpretation and Academic Argument

In this study, eight English professors thought aloud as they read four lyric poems and composed a short text proposing a hypothetical talk about them for a professional conference. The study used a crossed design in which participants read a poem in each of the following conditions: familiar to them and close to their professional writing, familiar and far, unfamiliar and close, unfamiliar and far. When reading familiar poems, participants produced longer protocols and more elaborate interpretations. When planning their conference talks, participants produced longer protocols for poems that were far from their professional writing as they struggled to access sufficient background knowledge. Participants attempted to say something “new” about the poems, and they closely monitored the limits of their knowledge. These results suggest that English professors, just like experts in other disciplines, develop both “generic” and “specific” expertise. Implications for expertise research, literature instruction, and academic literary scholars are considered.     

A General Setting for Dedekind's Axiomatization of the Positive Integers

A Dedekind algebra is an ordered pair (B, h), where B is a non-empty set and h is a similarity transformation on B. Among the Dedekind algebras is the sequence of the positive integers. From a contemporary perspective, Dedekind established that the second-order theory of the sequence of the positive integers is categorical and finitely axiomatizable. The purpose here is to show that this seemingly isolated result is a consequence of more general results in the model theory of second-order languages. Each Dedekind algebra can be decomposed into a family of disjoint, countable subalgebras called the configurations of the algebra. There are ?₀ isomorphism types of configurations. Each Dedekind algebra is associated with a cardinal-valued function on ω called its configuration signature. The configuration signature counts the number of configurations in each isomorphism type that occurs in the decomposition of the algebra. Two Dedekind algebras are isomorphic iff their configuration signatures are identical. The second-order theory of any countably infinite Dedekind algebra is categorical, and there are countably infinite Dedekind algebras whose second-order theories are not finitely axiomatizable. It is shown that there is a condition on configuration signatures necessary and sufficient for the second-order theory of a Dedekind algebra to be finitely axiomatizable. It follows that the second-order theory of the sequence of the positive integers is categorical and finitely axiomatizable.     

Sales Technology Applications: Interactive Video Technology in Sales Training: A Case Study

Interactive video (IV), a new technology for training, has had a recent surge in popularity. The use of interactive video technology has been reported to reduce training costs, increase quality, and decrease the amount of time required for training. The major characteristics of this new technology are presented. A state-of-the-art application of an IV system for sales training developed at BellSouth Services is discussed. The results confirm that IV is a promising new sales training tool.     

SPSS and SAS programs for comparing Pearson correlations and OLS regression coefficients

Several procedures that use summary data to test hypotheses about Pearson correlations and ordinary least squares regression coefficients have been described in various books and articles. To our knowledge, however, no single resource describes all of the most common tests. Furthermore, many of these tests have not yet been implemented in popular statistical software packages such as SPSS and SAS. In this article, we describe all of the most common tests and provide SPSS and SAS programs to perform them. When they are applicable, our code also computes 100 × (1 ? α)% confidence intervals corresponding to the tests. For testing hypotheses about independent regression coefficients, we demonstrate one method that uses summary data and another that uses raw data (i.e., Potthoff analysis). When the raw data are available, the latter method is preferred, because use of summary data entails some loss of precision due to rounding.     

Assessment of dispositional embarrassability

Abstract

Embarrassability, the propensity for an individual to experience embarrassment, has been frequently acknowledged as an important personality characteristic. The present research sought to explore the dispositional features of embarrassability by the psychometric development of 25-item measure, the Susceptibility to Embarrassment Scale (SES). The SES was designed to describe the personality characteristics of easily embarrassed persons rather than reactions to potentially embarrassing situations. The results indicated that the SES was an internally consistent and temporally stable measure. Its items were uncontaminated by social desirability. Assessments of construct validity suggested that the scale was a valid measure of embarrassability, and specifically a better measure of dispositional components of embarrassability than the only alternative measure of the construct. The location of the SES within the Big Five structure of normal adult personality is presented as well as its relationship with measures of deviant personality.     

Rising Up From Down Under: A Response To Adams-Webber On Cognitive Psychology And Personal Construct Theory

This article is a response to Adams-Webber's (1990) critique of my discussion of the relation between personal construct theory and cognitive psychology (Warren, 7990). Several points of specific disagreement are raised in an effort to clarify my own position. Furthermore, this clarification highlights the need for “integrationist” perspectives to clearly and directly address the problems, as well as the prospects, of relating personal construct theory to other perspectives in psychology.     

A systematic review of research on religion and spirituality in the Journal of Traumatic Stress: 1990–1999

Surveys reveal that religion and spirituality are highly valuable to many people in times of crisis, trauma, and grief. The relationship between coping with trauma and the use of various spiritual beliefs is well established. The importance of clergy in trauma recovery is also well documented. A review of the 469 research and non-research articles published between 1990 and 1999 in the Journal of Traumatic Stress revealed that 8.7% (6/69) of non-research articles, 4.1% (15/366) of quantitative research articles and 2.9% (1/34) of qualitative research articles considered religion or spirituality in their work. Analysis of variance found a significant overall increase in the percentage of articles that mentioned religion/spirituality between the first half (1990–1994) and the second half (1995–1999) of the study period. The results are discussed in the context of the trauma research and in comparison to related disciplines. Recommendations for future research and clinical application are suggested for both traumatologists and religious scholars.     

Body checking and avoidance in ethnically diverse female college students

Although body checking and avoidance behaviors are common in women with eating disorders, minimal research has examined the nature or correlates of these behaviors in ethnically diverse female college students without eating disorders. Self-identified European American (n = 268), Asian American (n = 163), Latina (n = 146), and African American (n = 73) women completed self-report measures of body checking and avoidance, thin-ideal internalization, eating pathology, and clinical impairment. Results indicated that European and Asian American women reported significantly more body checking and avoidance than African American and Latina women. Generally, correlates of body checking and avoidance were consistent across ethnic groups: Regression analyses indicated that type of ethnicity predicted body checking and avoidance; and ethnicity, body checking, and body avoidance predicted eating pathology and clinical impairment. These associations suggest that body checking and avoidance are not benign behaviors in diverse nonclinical women.
