Executive function on the Psychology Experiment Building Language tests

The measurement of executive function has a long history in clinical and experimental neuropsychology. The goal of the present report was to determine the profile of behavior across the lifespan on four computerized measures of executive function contained in the recently developed Psychology Experiment Building Language (PEBL) test battery and evaluate whether this pattern is comparable to data previously obtained with the non-PEBL versions of these tests. Participants (N = 1,223; ages, 5–89 years) completed the PEBL Trail Making Test (pTMT), the Wisconsin Card Sort Test (pWCST; Berg, Journal of General Psychology, 39, 15–22, 1948; Grant & Berg, Journal of Experimental Psychology, 38, 404–411, 1948), the Tower of London (pToL), or a time estimation task (Time-Wall). Age-related effects were found over all four tests, especially as age increased from young childhood through adulthood. For several tests and measures (including pToL and pTMT), age-related slowing was found as age increased in adulthood. Together, these findings indicate that the PEBL tests provide valid and versatile new research tools for measuring executive functions.     

SalesLitDB: A Classification System and Index of the Sales-Related Literature

The literature about personal selling and sales management appearing in journals has grown approximately tenfold in the past 20+ years. Despite the growth of huge online literature databases, there has been no single source that catalogs all of this literature, making it difficult to learn about articles of potential interest. This paper describes an ongoing research project devoted to developing a free subject-matter database of all sales-related articles appearing in academic journals, now available at www.saleslitdb.com. Readers are encouraged to make use of this resource and to contribute to it.     

Selling and Sales Management in Action: The Sales Force's Role in International Marketing Research and Marketing Information Systems

Many companies resist global markets because of seemingly insurmountable problems with these markets. Salespeople are often used successfully to gather market information. There is a wealth of market data that can be collected by a company's international sales force and distributors' sales force which can prove to be valuable in surmounting cultural and marketing barriers associated with global markets. The current paper discusses how and with what success U.S. multinational companies are using their international sales forces in gathering international marketing research data.     

‘It's like there are two people in my head’: A phenomenological exploration of anorexia nervosa and its relationship to the self

This study explores the lived experience of anorexia nervosa from the perspective of those who use pro-recovery websites for eating disorders. Fourteen people participated in an online focus group or an e-interview. Data were analysed using interpretative phenomenological analysis. Participants described their disorder as a functional tool for avoiding and coping with negative emotions, changing their identity and obtaining control. A central theme was the experience of an ‘anorexic voice’ with both demonic and friendly qualities. This voice felt like an external entity that criticised individuals and sometimes dominated their sense of self, particularly as anorexia nervosa got worse. Applying dialogical theory suggests a new model of anorexia nervosa, where the anorexic voice is a self-critical position, which disagrees with and attempts to dominate the more rational self. It is suggested that to move on from anorexia nervosa, the individual needs to address his/her anorexic voice and develop a new dominant position that accepts and values his/her sense of self.     

A kinematic comparison of successful and unsuccessful tennis serves across the elite development pathway

While velocity generation is an obvious prerequisite to proficient tennis serve performance, it is also the only stroke where players are obliged to negotiate a unique target constraint. Therefore, the dearth of research attending to the accuracy component of the serve is surprising. This study compared the body, racquet and ball kinematics characterising successful serves and service faults, missed into the net, in two groups of elite junior female players and one professional female tennis player. Three-dimensional body, racquet and ball kinematics were recorded using a 22-camera VICON motion analysis system. There were no differences in body kinematics between successful serves and service faults, suggesting that service faults cannot be attributed to a single source of biomechanical error. However, service faults missing into the net are characterized by projection angles significantly further below the horizontal, implying that consistency in this end-point parameter is critical to successful performance. Regulation of this parameter appears dependent on compensatory adjustments in the distal elbow and wrist joints immediately prior to impact and also perceptual feedback. Accordingly, coordination of the distal degrees of freedom and a refined perception-action coupling appear more important to success than any isolated mechanical component of the service action.     

The discrimination of angry and fearful facial expressions in 7-month-old infants: An event-related potential study

The important ability to discriminate facial expressions of emotion develops early in human ontogeny. In the present study, 7-month-old infants’ event-related potentials (ERPs) in response to angry and fearful emotional expressions were measured. The angry face evoked a larger negative component (Nc) at fronto-central leads between 300 and 600 ms after stimulus onset when compared to the amplitude of the Nc to the fearful face. Furthermore, over posterior channels, the angry expression elicited a N290 that was larger in amplitude and a P400 that was smaller in amplitude than for the fearful expression. This is the first study that shows that the ability of infants to discriminate angry and fearful facial expressions can be measured at the electrophysiological level. These data suggest that 7-month-olds allocated more attentional resources to the angry face as indexed by the Nc. Implications of this result may be that the social signal values were perceived differentially, not merely as “negative”. Furthermore, it is possible that the angry expression might have been more arousing and discomforting for the infant compared with the fearful expression.     

Can the LTSI Predict Transfer Performance? Testing intent to transfer as a proximal transfer of training outcome

Law enforcement personnel (n = 235) were administered the Learning Transfer Systems Inventory (LTSI) and a transfer measure after completing leadership development training. Although most studies using the LTSI have focused on validation efforts in different linguistic settings, this study is one of the few to examine the relationship between the LTSI factors and a proximal transfer outcome score (as measured by intent to transfer). Motivation to transfer, transfer design, and transfer performance expectations had the strongest relationship with intent to transfer, and the motivation subscales (motivation to transfer, performance expectations, and outcome expectations) accounted for the largest amount of unique variance in intent to transfer.     

“I Fired My Last Doctor for Not Taking Me Seriously”: Collaborating With a Difficult Medical Patient in a Multidisciplinary Primary Care Facility

We present the case of a multidisciplinary primary care assessment of a 32-year-old woman with multiple medical and psychological complaints. Following the collaborative care model, this assessment was conducted by a team consisting of a clinical health psychologist, Dr. J. L. Skillings, and a family physician, Dr. W. J. Murdoch. We describe the primary care environment in which this referral was made including the methods that were utilized to insure a successful professional collaboration. We report the results and recommendations from a comprehensive biopsychosocial assessment; we place emphasis on the psychological diagnosis and pain symptoms. We also describe the feedback session in which the assessment results were provided to the patient and her spouse by both physician and psychologist. Multiperspective commentary about the assessment is offered by the patient and her husband as well as the physician and psychologist assessors.
