The assessment of subjective visual vertical: comparison of two psychophysical paradigms and age-related performance

Perception of the subjective visual vertical (SVV) is usually assessed by asking to subjects, in complete darkness, to adjust the position of a luminous rod that is variably tilted (i.e., by the method of adjustment [ADJ]). Conversely, the two-alternative forced choice (2AFC) method requires subjects to categorize, as tilted either clockwise (CW) or counterclockwise (CCW), stimuli that are presented on a computer screen and are variably tilted from vertical. In this study, we aimed to compare the results of these two methods and investigate age-related effects on the SVV. SVV was assessed in 102 healthy individuals, 50 women and 52 men, with a mean age of 45.7 (range 20–91), using both ADJ (ten trials, initial 1°, 2°, 4°, 8°, or 12° bar tilts both CW and CCW) and 2AFC (120 stimuli with a 1°–32° variable tilt). Also, 50 of the subjects performed the ADJ test twice, with different bar lengths. We estimated bias and threshold for the two methods, and found that neither measure differed across the methods. Age was a significant predictor of threshold (2AFC, R ² = .141; ADJ, R ² = .190; p < .001), implying lower sensitivity with increasing age. Moreover, the ADJ method showed a significant increase of bias when the initial tilt was farthest from vertical, whereas the rod length was irrelevant. SVV measures obtained with the ADJ and 2AFC methods were comparable, but the latter measures were more resistant to artifacts that might affect the measurement. The lower sensitivity found in older persons may have an influence on their ability to interact with the environment and may contribute to impairment of postural control.     

Flexing Work Boundaries: The Spillover and Crossover of Workplace Support

Using boundary theory and conservation of resources theory, we examined how job incumbents’ perceptions of supervisor instrumental support and organizational segmentation support influence outcomes for both the incumbent and the spouse. First, we examined how supervisor instrumental support and organizational segmentation support shape incumbents’ perceived ability to flex work boundaries and thus affect their experience of family functioning and their organizational commitment. Second, we examine the effects of supervisor instrumental support and organizational segmentation support on spousal martial satisfaction and the spouse's commitment to the incumbent's employing organization as mediated through boundary flexibility and the spouse's perception of successful boundary management by the incumbent. Using a matched set of 503 subordinates and their spouses, this study found that both supervisor instrumental support and organizational segmentation support contribute to work boundary flexibility. Further, for the incumbent, family functioning and organizational commitment were enhanced through work boundary flexibility, whereas for the spouse, marital satisfaction and commitment to the incumbent's organization were enhanced through both incumbent work boundary flexibility and the spouse's perception of successful boundary management by the incumbent. We discuss the study's implications for theory, research, and practice while suggesting new research directions.     

Exploring Lawyer Misconduct: An Examination of the Self-Regulation Process

Although white-collar professionals are often held in high esteem, sometimes persons in privileged positions engage in misconduct. Unfortunately, very little is known about the correlates associated with professional misconduct and even less is known about the sanctioning process among lawyers who are licensed by state bar associations and therefore subject to the bar rules regulating their professional conduct. We examine 213 complaints filed in one fiscal year with the Florida Bar, alleging attorney misconduct and evaluate the factors that influence whether the complaint continued through, or was discarded at, each stage of the self-regulated grievance process. Using selection models that examine both the staff’s decision to send a case forward to the grievance committee as well as the grievance committee’s recommendation about sanctioning the lawyer, results show that both legal and extra-legal variables are related to these two processes.     

Modules in spatial vision: intrinsic reasons of their functional attributes

Visual modules can be viewed as expressions of a marked analytic attitude in the study of vision. In vision psychology, this attitude is accompanied by hypotheses that characterize how visual modules are thought to operate in perceptual processes. Our thesis here is that there are what we call “intrinsic reasons” for the presence of such hypotheses in a vision theory, that is, reasons of a deductive kind, which are imposed by the partiality of the basic terms (input and output) in the definition of a module, and by peculiar characteristics of those terms. Specifically, we discuss three hypotheses of functional attributes: successive stages in the action of modules, residual indeterminacy of their effects, and the role of prior constraints. For each of the three, we indicate its occurrence in perceptual psychology, explain corresponding intrinsic reasons, and illustrate such reasons with examples.     

Lessons from Freelancing,Lighting Design to Genetic Counseling

Theatrical lighting design and genetic counseling may seem like antipodal career choices. The former was chosen from a belief in the dynamism of the theatrical experience, as well as love of the actual work. As I grew older, the powerful personal experiences of a life encompassing miscarriages, the birth of a child with a genetic disorder, and breast cancer profoundly directed my choice of a new career; one that I also love. Clearly, the day-to-day work is very different. However, people in both professions strive to create a transformative space for their respective public. Rather than being left behind, lessons learned by working as a freelancer have served as a source of inspiration as I have matured into my new career. Three specific strategies, supported by literature on career models, have been paramount. First, keeping an eye on the big picture encourages awareness of where the field of genetics and the genetic counseling job market are headed. That awareness leads to the advocacy necessary to achieve the outcomes genetic counselors want. Second, striving for continual personal growth keeps genetic counselors engaged and personally ready for professional changes. Third, networking provides the connections to make clinical and advocacy efforts successful, in addition to essential social support.     

Evaluating the temporal structure and correlates of daily self-esteem using a trait state error framework (TSE)

This study evaluates the temporal structure of daily self-esteem and the relative contribution of a range of theoretically motivated predictors of daily self-esteem. To assess self-esteem stability, a daily version of the Rosenberg Self-Esteem scale (RSE, Rosenberg, 1965) was administered to 278 undergraduates for five consecutive days. These short-term longitudinal data were analysed using the Trait State Error (TSE) modelling framework. The TSE decomposes multi-wave data into three components: (1) a stable trait component, (2) a state component, and (3) an error component. Significant predictors of the trait component of self-esteem observed across five days were: (1) emotional stability, and (2) the congruence between implicit and explicit self-esteem. Significant predictors of the state components of self-esteem were daily positive and negative events. We discuss the implications of these results for future research concerning self-esteem stability.
