Gone to the Spirits: A Transgender Prophet on the Columbia Plateau

This article examines the life of Kaúxuma núpika, an indigenous transgender prophet living on the Columbia Plateau in the early nineteenth century. As a Ktunaxa woman, she crossed cultural boundaries to marry a Euroamerican. When she left her husband, insisting on her independence and autonomy, she crossed another frontier. When Kaúxuma núpika declared herself no longer a woman, but a man, and secured himself a wife, he crossed further boundaries of gender and sexuality. As a warrior and a prophet, Kaúxuma núpika crossed the boundaries to the world of the spirit, returning with warnings, guidance, and hope for the tribal people of the Columbia River valley. In this project, I reflect upon the historical record in light of indigenous prophet traditions on the Columbia Plateau and current scholarship on gender and power among Native communities of the region, to consider notions of power, identity, and the religio-cultural dynamics of gender and sexual identity among indigenous communities on the Columbia Plateau.     

Counselling former members of charismatic groups: considering pre-involvement variables,reasons for joining the group and corresponding values

A majority of counsellors and other health professionals who work with former members of charismatic groups appear to give little consideration to pre-involvement variables such as reasons for initially joining the group and corresponding values. This study explores reasons for joining a charismatic group from the perspective of former members through the use of qualitative methods. Seven participants from four different groups were recruited via purposive sampling and modified snowball sampling. In-depth interviews were used to explore the participants’ accounts of why they joined a charismatic group. The findings of this study suggest that participants of this study joined charismatic groups because of the ability of such groups to provide ‘certainty’ and meet needs of friendship, meaning, and belonging. The need for health professionals to consider pre-involvement variables when working with former members is discussed.     

The culture of yoga retreats,active followers and peripheral associates of new religious movements: wellness enterprises promoting well-being

ABSTRACT

This paper examines the wellness effects of yoga retreats on Indian guru-led new religious movements’ (NRMs) fellowship. The two-year repeated-measures study included 3658 active followers and 3658 peripheral associates as the comparison group. Two measures assessed wellness: the Flourishing Scale (FS) and the Comprehensive Inventory of Thriving (CIT). Phase 1 scores of both groups were not significantly different. Active followers who attended yoga retreats scored higher at phase 2 on the FS and the CIT than the peripheral associates. Within the active followers’ cohort, women, upper class, Hindus and never married/widowed had higher phase 2 FS and CIT scores. Active followers who attended retreats for meditation and reflection, practiced yoga, prayer and personal study during retreats, and regularly maintained the spiritual routine after retreats, acquired several psychological resources and strengths. Hence, active and serious followers of the Indian guru-led NRMs psychologically gain as a result of experiencing yoga retreats.     

Roles of Visual Information for Control of Reaching Movements in Children

Poststroke hemiparetic individuals (n = 9) and a control group (n = 9) completed a frequency-scaled circle-drawing task in unimanual and bimanual conditions. Measures of intralimb spatial and temporal task accuracy and interlimb coordination parameters were analyzed. Significant reductions in task performance were seen in both limbs of the patients and controls with the introduction of bimanual movement. Spatial performance parameters suggested that the 2 groups focused on different hands during bimanual conditions. In the controls, interlimb coordination variables indicated predictable hand dominance effects, whereas in the patient group, dominance was influenced by the side of impairment and prior handedness of the individual. Therefore, in this particular bimanual task, performance improvements in the hemiplegic side could not be elicited. Intrinsic coupling asymmetries between the hands can be altered by unilateral motor deficits.     

Linking cognitive and reaching trajectories via intermittent movement control

Theories of decision-making have traditionally been constrained by reaction time data. A limitation of reaction time data, particularly for studying the temporal dynamics of cognitive processing, is that they index only the endpoint of the decision making process. Recently, physical reaching trajectories have been used as proxies for underlying mental trajectories through decision space. We suggest that this approach has been oversimplified: while it is possible for the motor control system to access the current state of the evidence accumulation process, this access is intermittent. Instead, we demonstrate how a model of arm movements that assumes intermittent, not continuous, access to the decision process is sufficient to describe the effects of stimulus quality and viewing time in curved reaching movements.     

Response Facilitation and Inhibition in Manual,Vocal, and Oculomotor Performance: Evidence for a Modality-Unspecific Mechanism

In 2 experiments (N = 10, Experiment 1; N = 16, Experiment 2), the authors investigated whether evidence for response facilitation and subsequent inhibition elicited by masked prime stimuli can be observed for output modalities other than manual responding. Masked primes were followed by target stimuli that required a 2-choice manual, saccadic, or vocal response. Performance was measured for compatible trials in which primes and targets were identical and for incompatible trials in which they were mapped to opposite responses. When primes were presented centrally, performance benefits were obtained for incompatible trials; whereas for peripherally presented primes, performance benefits were found in compatible trials. That pattern of results was obtained for manual responses and for saccadic eye movements (Experiment 1), demonstrating that those effects are not mediated by specialized dorsal pathways involved in visuomanual control. An analogous pattern of effects was found when manual and vocal responses were compared (Experiment 2). Because vocal responding is controlled by the inferotemporal cortex, that result shows that prime-target compatibility effects are not primarily mediated by the dorsal stream, but appear to reflect modality-unspecific visuomotor links that allow rapid activation of motor responses that may later be subject to inhibition.     

The Visuomotor System Resists the Horizontal-Vertical Illusion

The effect of the horizontal-vertical illusion on the visual and visuomotor systems was investigated. Participants (N = 8) viewed horizontal and vertical lines in an inverted-T stimulus and judged whether the two line segments were the same or different lengths. Participants also reached out and grasped either the vertical or the horizontal line segment of the stimulus. Perceptually, participants succumbed to the illusion; that is, they judged Ts of equal horizontal and vertical line lengths to be different and Ts of unequal line lengths to be the same. When reaching toward the same stimuli, however, the size of their grip aperture was scaled appropriately for the various line lengths. Thus, whereas the perceptual system succumbed to the illusion, the visuomotor system did not. Those results support a model proposed by M. A. Goodale and A. D. Milner (1992), who posited separate cortical pathways for visual perception and visually guided action.     

A Modeling Study of Potential Sources of Curvature in Human Reaching Movements

The authors of this article suggest that the slight but consistent posture-dependent curvature of the spatial paths in the kinematic transformation between intrinsic and extrinsic coordinates may result in a systematic curvature of movements initially planned as straight-line trajectories toward the target. A kinematic planning model is presented that takes into account the anisotropy of the intrinsic and extrinsic transformation and tends to avoid movements that require excessive joint rotations by introducing slight deviations from a straight-line trajectory. Preliminary simulations showed reasonably good agreement with experimental data, especially considering that the current model is strictly based on kinematics. A quantitative analysis showed that the strategy used in the model achieves a favorable compromise between straight-line movements and angular joint changes: By slightly increasing the spatial length of the movement (i.e., by introducing curvature), an individual can greatly reduce the total amount of joint rotation required to produce the movement.     

The Confusion of Fear and Surprise: A Developmental Study of the Perceptual-Attentional Limitation Hypothesis Using Eye Movements

The goal of the present study was to test the Perceptual-Attentional Limitation Hypothesis in children and adults by manipulating the distinctiveness between expressions and recording eye movements. Children 3–5 and 9–11 years old as well as adults were presented pairs of expressions and required to identify a target emotion. Children 3–5 years old were less accurate than those 9–11 years old and adults. All children viewed pictures longer than adults but did not spend more time attending to the relevant cues. For all participants, accuracy for the recognition of fear was lower than for surprise when the distinctive cue was in the brow only. They also took longer and spent more time in both the mouth and brow zones than when a cue was in the mouth or both areas. Adults and children 9–11 years old made more comparisons between the expressions when fear comprised a single distinctive cue in the brow than when the distinctive cue was in the mouth only or when both cues were present. Children 3–5 years old made more comparisons for brow only than both. The results of the present study extend on the Perceptual-Attentional Limitation Hypothesis showing an importance of both decoder and stimuli, and an interaction between decoder and stimuli characteristics.     

The Visuomotor Mental Rotation Task: Visuomotor Transformation Times Are Reduced for Small and Perceptually Familiar Angles

In the visuomotor mental rotation (VMR) task, participants point to a location that deviates from a visual cue by a predetermined angle. This task elicits longer reaction times (RT) relative to tasks wherein the visual cue is spatially compatible with the movement goal. The authors previously reported that visuomotor transformations are faster and more efficient when VMR responses elicit a degree of dimensional overlap (i.e., 0° and 5°) or when the transformation involves a perceptually familiar angle (i.e., 90° or 180°; K. A. Neely & M. Heath, 2010b). One caveat to this finding is that standard and VMR responses were completed in separate blocks of trials. Thus, between-task differences not only reflect the temporal demands of the visuomotor transformations, but also reflect the temporal cost of response inhibition. The goal of this study was to isolate the time cost of visuomotor transformations in the VMR task. The results demonstrated that visuomotor transformations are more efficient and effective when the response entails a degree of dimensional overlap between target and response (i.e., when the angular disparity between the responses is small) or when the transformation angle is perceptually familiar.
