Intuitive covariation assessment of the illusory correlation

Most of the research concerned with the illusory correlation is modeled after the seminal work of D. L. Hamilton and R. K. Gifford (1976). However, S. A. Haslam and C. McGarty (1994) have voiced concerns over the dependent measures used within this paradigm. Therefore, in this study, the authors tested a new dependent variable that has high face validity. This measure was modeled after the work of J. R. McGahan and R. Wight (1989) and consisted of a set of propositional statements representing either the illusory correlation, the contingency opposite the illusory correlation, or the noncontingency. A second purpose of this study was to validate other studies that have used dependent measures modeled after the work of J. R. McGahan and R. Wight (1989). Demonstrating that this measure can be used to detect a well-documented phenomenon (i.e., the illusory correlation) would strengthen the results and conclusions from other studies. To this end, results from 2 experiments indicate that this measure does provide a valid alternative to those measures that are commonly used in illusory correlation studies. The results thereby give credence to other studies that have used similar dependent measures.     

Improving return rates for health-care outcome

The objective was to test two methods of reducing loss of data in follow-up by abbreviating the questionnaire and offering a token monetary incentive. Primary data were collected between September 14, 1998 and July 23, 1999 from an adult psychiatric population, representing about 50% of all patients, all of whom agreed to participate in a quality-assurance monitoring program. Briefer components of the SF-36 Health Status Survey were expected to yield higher return rates than would the SF-36 plus a form assessing amount of treatment received. Small monetary incentives were expected to result in higher return rates also. Patients were randomly assigned to the groups (n = 73 each). Abbreviation of the questionnaire and use of a monetary incentive each reduced attrition by 10%. A diminishing returns effect for both methods was observed. Further study of a possible interaction between the questionnaire's length and monetary incentive is recommended.     

Psychometric properties of the Hawaiian Culture Scale--Adolescent Version

This article reports on the psychometric properties of a newly constructed Hawaiian Culture Scale--Adolescent Version. A total of 2,272 Native Hawaiian and 1,170 non-Hawaiian adolescents were administered this 50-item inventory that measures the source of learning the Hawaiian way of life, how much Hawaiian beliefs are valued and important to maintain, how much non-Hawaiian beliefs are valued, Hawaiian blood quantum, and specific cultural traditions (seven subscales = Lifestyles, Customs. Activities, Folklore, Causes-Locations, Causes-Access, and Language Proficiency). The results strongly supported the internal consistency and validity of the measures for both the Hawaiian and non-Hawaiian groups. On the basis of the demographic data, partial support was offered for cross-cultural theories of ethnic identity. More consistent support was found for multiculturalism in Hawai'i's adolescents. Further research is needed to link these measures with indicators of psychological adjustment (e.g., depression, anxiety, substance use).     

The roles of inducer size and distance in the Ebbinghaus illusion (Titchener circles)

Although the Ebbinghaus illusion is commonly used as an example of a simple size-contrast effect, previous studies have emphasised its complexity by identifying many factors that potentially influence the magnitude of the illusion. Here, in a series of three experiments, we attempt to simplify this complexity. In each trial, subjects saw a display comprising, on one side, a target stimulus surrounded by inducers and, on the other, an isolated probe stimulus. Their task was to indicate whether the probe appeared larger or smaller than the target. Probe size was adjusted with a one-up, one-down staircase procedure to find the point of subjective equality between probe and target. From these experiments, we argue that the apparent effects of inducer size are often confounded by the relative completeness of the inducing surround and that factors such as the similarity of the inducers and target are secondary. We suggest a simple model that can explain most of the data in terms of just two primary and independent factors: the relative size of the inducers and target, and the distance between the inducers and the target. The balance between these two factors determines whether the size of the target is underestimated or overestimated.     

Priming dominant and unusual senses of ambiguous words

The priming technique was used to investigate the conditions under which a homograph’s dominant and/or nondominant semantic sense will be retrieved. Subjects verified whether “A(n) A is a(n) B” when A was an ambiguous word and B was a word corresponding to either a dominant or an unusual semantic sense of word A. When word B most often corresponded to the dominant sense of word A (Experiment I), a Priming by Dominance interaction was obtained in the reaction time (RT) data; viz, the facilitatory effect of priming was greater for the dominant-sense sentences than for the unusual-sense sentences. When the word B equally often corresponded to the dominant and unusual senses of A (Experiment 2), the facilitatory effect of priming was equal for the dominant-sense and unusual-sense sentences. These results were interpreted within the framework of a two-stage model of lexical access (d. Posner & Snyder, 1975; Neely, 1977). An application of this two-stage model to the now rather extensive literature on homographic processing helps clear up the apparent contradictions that have been prevalent in this literature.     

Baseline reaction time predicts 12-month smoking cessation outcome in formerly depressed smokers.

Burgeoning evidence points to a positive association between cigarette smoking and depression. Moreover, depressive symptomatology, whether historical, current, or subsyndromal, appears to negatively influence smoking cessation efforts. Whereas depression is typically assessed via clinical interview or self-report, rarely are the known neurocognitive deficits linked to depression (e.g., global slowing) assessed in the context of smoking cessation research. Hence, this study examined whether simple reaction time -- color naming of affectively neutral words -- is predictive of 12-month smoking cessation outcome among a sample of formerly depressed smokers (N = 28). Results revealed a significant, positive correlation between reaction time and depressive symptoms such that those who exhibited slower reaction times were at heightened risk to relapse. Baseline depressive symptoms, as assessed via self-report, neither correlated with nor predicted smoking cessation outcome. Results from logistic regression analyses further showed that reaction time added incremental variance to the prediction of smoking cessation outcome. Therefore, simple reaction time may capture aspects of depression not typically assessed in self-report questionnaires. These results are discussed in terms of their theoretical and clinical implications for smoking cessation research.     

The acute effects of nicotine on positive and negative affect in adolescent smokers

Although adolescent cigarette smoking remains a critical public health concern, little is known about the reinforcing mechanisms governing smoking in this vulnerable population. To assess predictions derived from both positive and negative reinforcement models of drug use, the authors measured the acute effects of nicotine, as administered via tobacco cigarettes, on both positive and negative affect in a group of 15- to 18-year-old smokers. A matched group of nonsmokers served as a comparison group. Findings revealed that whereas adolescents who smoked a cigarette experienced reductions in both positive and negative affect, the observed reductions in negative affect were moderated by nicotine content of the cigarette (high yield vs. denicotinized), level of nicotine dependence, level of baseline craving, and smoking expectancies pertinent to negative affect regulation. Nonsmokers experienced no change in affect over the 10-min assessment period, and no interaction effects were observed for positive affect. Overall, the findings conform to a negative reinforcement model of nicotine effects and strongly suggest that, even among young light smokers, nicotine dependence and resultant withdrawal symptomatology may serve as motivating factors governing smoking behavior.     

Web Site Design, Self-Monitoring Style, and Consumer Preference

This study aims to advance understanding of Internet interactions by considering the impact of Web site design and self-monitoring style on consumer preference. Four quasi-commercial Web sites were constructed containing identical information presented via a context-based (animated) or content-based (unanimated) design, and 2 advertisements of either image- or information-oriented style. Using a between-participants design, the study found that all individuals favored context-based over content-based Web site design. Matching advertising appeal to individual self-monitoring needs was found to increase Web site effectiveness of consumer preference for high self-monitors, and within Web site satisfaction and level of persuasion for low self-monitors. Results suggest that to reach their potential as a consumer-sensitive tool, Web sites must be engaging in their design and tailor their communications to accommodate individual differences.     

‘If you look the part you’ll get the job’: should career professionals help clients to enhance their career image?

This article presents a critical exploration of the role of career professionals in supporting people to reflect on and enhance their appearance, attractiveness and self-presentation (career image). The article is conceptual and based on a review of the broader literature on career success, appearance and attractiveness. It explores the evidence for a relationship between attractiveness and career, and the authors propose a conceptual framework in which career image is comprised of three elements (interpersonal skills, aesthetic presentation and beauty). The paper examines a possible role for career professionals in relation to this and then critically examines this role and concludes with the proposition of a research agenda in this area.
