Understanding the influence of literacy on consumer memory: The role of pictorial elements

This research examines the relationship between literacy and consumer memory. The effects of a variety of stimuli at exposure (i.e., brand names, brand signatures, and products in usage) on memory (i.e., recognition, stem-completion tasks) were examined for a range of literacy. In a series of experiments, we find that the use of pictorial representations of brands (i.e., brand signatures) results in superior brand memory for individuals with lower literacy levels when compared to those at higher literacy levels. This effect is shown to occur not due to pictorial elements per se, but due to pictorial elements with a 1-to-1 correspondence with reality, i.e., which match the form in which they were originally encoded in memory. Moreover, this effect does not persist with stimulus-rich pictures of brands in usage, pointing to boundary conditions with the use of pictorial information.     

Does adaptive training work?

People intuitively alter the allocation of study time between items of varying difficulty, and such adaptive learning methods are widely used in education and in commercially available memory training programs. We investigated the effectiveness of a computer‐based adaptive learning system that utilises spacing and repetition effects by presenting difficult items with short gaps to establish fast learning, and easy items with long intervals to optimise long‐term retention. The immediate and delayed effects of adaptive training on cued recall were investigated relative to a control condition of non‐adaptive, random spacing. Adaptive training produced significantly higher immediate and delayed recall rates than random spacing. These results encourage the use of adaptive training in education and rehabilitation.

The “Ethical” Professor and the Undergraduate Student: Current Perceptions of Moral Behavior among Business School Faculty

A survey of 830 faculty members at 89 AASCB-accredited business schools throughout the United States was conducted in Fall 2002 to develop a snapshot of perceptions of ethical and unethical conduct with regard to undergraduate business instruction across a wide range of business disciplines. These behaviors fell into such categories as course content, evaluation of students, educational environment, disrespectful behavior, research and publication issues, financial and material transactions, social relationships with students, and sexual relationships with students and other faculty. Of the 55 behaviors, two were almost universally perceived to be unethical. Eight behaviors were controversial in that there was wide variance on whether the behavior was perceived to be unethical. In addition, females' ethical perceptions differed significantly from males on three behaviors; older participants differed from younger participants on seven behaviors; participants at research-oriented institutions differed from participants at teaching-oriented institutions on one behavior; and tenured, untenured tenure-track, and untenured non-tenure-track participants differed on three behaviors. The findings of this study and the detailed comments of the respondents provide a starting point for discussing more systematic means to consider ethical issues within collegiate schools of business.     

The Career Satisfaction Scale: Response bias among men and women

Recent studies demonstrate an increasing emphasis on subjective career success. This construct is typically measured using self-report scales, with the most used instrument being the Career Satisfaction Scale of Greenhaus, Parasuraman, and Wormley [Greenhaus, J. H., Parasuraman, S., & Wormley, W. M. (1990). Effects of race on organizational experiences, job performance evaluations, and career outcomes. Academy of Management Journal, 33, 64–86]. As career success is often studied in relation to gender, one may wonder whether men and women rate subjective career success, as measured by the Career Satisfaction Scale (Greenhaus et al., 1990), in the same manner—which is an important requirement when interpreting sex differences. Therefore, this study provides a rigorous evaluation of the Career Satisfaction Scale (Greenhaus et al., 1990) in terms of measurement invariance. The results show that gender invariance of the Career Satisfaction Scale (Greenhaus et al., 1990) does not hold. Implications of these findings in terms of optimal measurement of the subjective career success construct are spelled out.     

Circulating fibrinogen but not D-dimer level is associated with vital exhaustion in school teachers

Meta-analyses have established elevated fibrinogen and D-dimer levels in the circulation as biological risk factors for the development and progression of coronary artery disease (CAD). Here, we investigated whether vital exhaustion (VE), a known psychosocial risk factor for CAD, is associated with fibrinogen and D-dimer levels in a sample of apparently healthy school teachers. The teaching profession has been proposed as a potentially high stressful occupation due to enhanced psychosocial stress at the workplace. Plasma fibrinogen and D-dimer levels were measured in 150 middle-aged male and female teachers derived from the first year of the Trier-Teacher-Stress-Study. Log-transformed levels were analyzed using linear regression. Results yielded a significant association between VE and fibrinogen (p = 0.02) but not D-dimer controlling for relevant covariates. Further investigation of possible interaction effects resulted in a significant association between fibrinogen and the interaction term "VE x gender" (p = 0.05). In a secondary analysis, we reran linear regression models for males and females separately. Gender-specific results revealed that the association between fibrinogen and VE remained significant in males but not females. In sum, the present data support the notion that fibrinogen levels are positively related to VE. Elevated fibrinogen might be one biological pathway by which chronic work stress may impact on teachers' cardiovascular health in the long run.

Psychological Hardiness Predicts Success in US Army Special Forces Candidates

Military ‘Special Forces’ represent a high‐reliability occupation, where stress levels are often intense and failure can be costly. Selection for such jobs should pay careful attention to psychological factors associated with resiliency under stress. In the present study, US Army Special Forces candidates (N=1138) were assessed for psychological hardiness using a short form of the Dispositional Resilience Scale, and these scores were then applied to predict successful completion of the course. Independent sample t‐tests and logistic regression analyses confirmed that Special Forces course graduates are significantly higher in psychological hardiness, as compared to non‐graduates. Psychological hardiness appears to be an important individual characteristic associated with stress tolerance and successful performance in highly demanding occupations.     

Blunted hippocampal, but not striatal, acetylcholine efflux parallels learning impairment in diencephalic-lesioned rats

A rodent model of diencephalic amnesia, pyrithiamine-induced thiamine deficiency (PTD), was used to investigate the dynamic role of hippocampal and striatal acetylcholine (ACh) efflux across acquisition of a nonmatching-to-position (NMTP) T-maze task. Changes in ACh efflux were measured in rats at different time points in the acquisition curve of the task (early=day 1, middle=day 5, and late=day 10). Overall, the control group had higher accuracy scores than the PTD group in the latter sessions of NMTP training. During the three microdialysis sampling points, all animals displayed significant increases in ACh efflux in both hippocampus and striatum, while performing the task. However, on day 10, the PTD group showed a significant behavioral impairment that paralleled their blunted hippocampal--but not striatal--ACh efflux during maze training. The results support selective diencephalic-hippocampal dysfunction in the PTD model. This diencephalic-hippocampal interaction appears to be critical for successful episodic and spatial learning/memory.     

Why is that? Structural prediction and ambiguity resolution in a very large corpus of English sentences

Previous psycholinguistic research has shown that a variety of contextual factors can influence the interpretation of syntactically ambiguous structures, but psycholinguistic experimentation inherently does not allow for the investigation of the role that these factors play in natural (uncontrolled) language use. We use regression modeling in conjunction with data from the British National Corpus to measure the amount and specificity of the information available for disambiguation in natural language use. We examine the Direct Object/Sentential Complement ambiguity and the closely related issue of complementizer use in sentential complements, and find that both ambiguity resolution and complementizer use can be predicted from contextual information.
