BACKGROUND: Dizziness affects 20–30%of the general population. A subgroup of dizzy patients with chronic migraine suffers vertigo implying that the migraine has a vestibular component. Vestibular migraine remains a diagnosis of exclusion based on history. OBJECTIVE: A link between headaches and dizziness suggests that these individuals would demonstrate dizziness and instability in complex, dynamic visual environments as a result of an inability to correctly process conflicting visual and vestibular signals. METHODS: A convenience sample of 74 patients (22 men and 52 women; average age 56.2 years) who presented with complaints of dizziness participated. Effects of Visual-Vestibular Mismatch (VVM) were measured using a modified VVM questionnaire. Visual dependence was measured as the error to subjective visual vertical using a computerized Rod and Frame test. RESULTS: Forty-two participants (56.8%) tested positive for VVM. Of these, 68.9%were patients with concomitant complaints of headaches. Visual dependence was present in 41.5%of all patients but showed no significant correlation with headache. 22.2%of patients had visual dependence and complained of headaches. CONCLUSIONS: These results demonstrate that sensory reweighting occurs in patients experiencing dizziness and headache, supports the role of vestibular involvement in this disorder, and provides future direction for novel interventions.

Rod And Frame

The rod-and-frame illusion shows large errors in the judgment of visual vertical in the dark if the frame is large and there are no other visible cues (Witkin and Asch, 1948 Journal of Experimental Psychology38 762–782). Three experiments were performed to investigate other characteristics of the frame critical for generating these large errors. In the first experiment, the illusion produced by an 11° tilted frame made by luminance borders (standard condition) was considerably larger than that produced by a subjective-contour frame. In the second experiment, with a 33° frame tilt, the illusion was in the direction of frame tilt with a luminance-border frame but in the opposite direction in the subjective-contour condition. In the third experiment, to contrast the role of local and global orientation, the sides of the frame were made of short separate luminous segments. The segments could be oriented in the same direction as the frame sides, in the opposite direction, or could be vertical. The orientation of the global frame dominated the illusion while local orientation produced much smaller effects. Overall, to generate a large rod-and-frame illusion in the dark, the tilted frame must have luminance, not subjective, contours. Luminance borders do not need to be continuous: a frame made of sparse segments is also effective. The mechanism responsible for the large orientation illusion is driven by integrators of orientation across large areas, not by figural operators extracting shape orientation in the absence of oriented contours.

Abstract Senior adults’ reliance on the visual frame of reference for spatial orientation is a manifestation of an age-related shift in cognitive style from field independence to field dependence. We implemented a virtual reality rod and frame test (VR-RFT) to assess visual field dependence (VFD) in n=39 young adults (20-30 years old) and n=43 seniors (60 years old and above). The subjects were asked to determine subjective visual vertical (SVV) for 19 angles of frame tilt (running from -45 degrees to 45 degrees in steps of 5 degrees). The strong VFD of seniors was manifested not only by the increased error in the determination of SVV (SVVE) but also in its distribution. For small and large frame tilt angles, seniors’ SVVE skewness and kurtosis were greater than those of young adults. The SVVE median dependence on frame tilt may be accounted for with a phenomenological model whose two parameters describe the strengths of primary (P) and secondary (S) visual attractors which subjects use to infer SVV: the edges of the frame and its imaginary diagonals. For young adults, these parameters were: PY=14.91 and SY=12.51. For seniors, we observed an over 50% increase in the strength of the primary attractor PS=26.31 while the strength of the secondary one was only weakly affected by aging: SS=13.74. We demonstrate that the asymmetry between the strength of attractors significantly contributes to SVVE made by seniors at large frame tilts. We hypothesize that a variant VR-RFT may be used in rehabilitation to reduce excessive VFD.

The Relationship

Colleges and universities have begun using the language of vocation and calling to help undergraduates think about the future direction of their lives. This language has been employed in both secular and religious contexts, but it has deep roots in a specific theological tradition. Given the increasingly multi-faith context of undergraduate life, many have asked whether this originally Christian terminology can truly become a new vocabulary for higher education. This volume’s 13 contributing scholars identify with a wide variety of faith traditions, including Buddhism, Christianity, Hinduism, Islam, Judaism, and Sikhism. Some claim more than one tradition; others would claim none. Rather than seeking to “translate” Christian language into other perspectives, they reflect on various facets of vocation from the standpoint of their own traditions. Both individually and collectively, they seek to expand the range of vocational reflection and discernment well beyond its traditional Christian origins, addressing themes such as religious pluralism and difference, the importance of multiple voices, the role of affective learning, the relationship between process and result, and the development of an integrated life. The authors recognize that all undergraduate students—regardless of their academic field, religious background, or demographic identity—need to make space for reflection, to overcome obstacles to vocational discernment, and to consider the significance of their own narratives, beliefs, and practices. Accomplishing these goals will require college campuses to reimagine their curricular and co-curricular programming in order to support their students’ interfaith reflections on issues of meaning and purpose, as well as personal identity.

Purpose: We examine pilot results for the culturally adapted Weaving Healthy Families (WHF) program to promote resilience and wellness while preventing substance abuse and violence among Native American (NA) families. Methods: Results were drawn from paired sample t tests and analyses of variance (ANOVA) with a convenience sample of 24 adults and adolescents from eight NA families (pretest, posttest, and, where available, 6-month postintervention). Results: Along with substance abuse reduction and prevention, t test results indicated reductions in (a) adult depressive symptoms and improvements in adult conflict resolution and health behaviors; (b) adolescent wellness; and (c) adult and adolescent resilience, communal mastery, social support, and sugar-sweetened beverage consumption. ANOVA tests revealed reductions in adult psychological and physical violence and improvements in adult and adolescent family resilience, family environment, and emotional regulation. Conclusions: Results reveal promising preliminary results for the WHF program to promote resilience and thriving while reducing risk for substance abuse and violence in NA families.

The digital clock drawing test is a fielded application that provides a major advance over existing neuropsychological testing technology. It captures and analyzes high precision information about both outcome and process, opening up the possibility of detecting subtle cognitive impairment even when test results appear superficially normal. We describe the design and development of the test, document the role of AI in its capabilities, and report on its use over the past seven years. We outline its potential implications for earlier detection and treatment of neurological disorders. We set the work in the larger context of the THink project, which is exploring multiple approaches to determining cognitive status through the detection and analysis of subtle behaviors.

Rod And Frame

The more successful 102 normal male university students were in following instructions to resist fluctuations of the Necker cube, the more field-independently they scored on both Series III of the rod-and-frame test ( r = .28) and on Jackson's short form of the embedded-figures test ( r = .24). Under neutral instructions, the correlations were nil. Results support prior findings that a small but significant portion of the variance of Necker cube fluctuations under instructions to control the rate of shift is related to scores of field independence. Results support Jackson's finding that ability to control the rate of shift is not related to intelligence.
