Females have been reported to be more ‘visually dependent’ than males. When aligning a rod in a tilted frame to vertical, females are more influenced by the frame than are males, who align the rod closer to gravity. Do females rely more on visual information at the cost of other sensory information? We compared the subjective visual vertical and the perceptual upright in 29 females and 24 males. The orientation of visual cues presented on a shrouded laptop screen and of the observer’s posture… 

Asymmetrical representation of body orientation.

An asymmetry of the PU was found to be best modeled by adding a leftward bias of 5.6° to the perceived orientation of the body relative to its actual orientation relative to the head, similar to the body-defined left-leaning asymmetry in the perceived direction of light coming from above.

Crossing the hands is more confusing for females than males

It is speculated that sex-specific differences in multisensory processing and spatial ability may explain why females are less able to disambiguate a crossed-hands posture than are males.

Do Visual and Vestibular Inputs Compensate for Somatosensory Loss in the Perception of Spatial Orientation? Insights from a Deafferented Patient

It is demonstrated that a massive somatosensory deficit substantially impairs the perception of spatial orientation, and that the use of the remaining sensory inputs available to a deafferented patient differs regarding whether the judgment concerns external vs. self-orientation.

Perceived Object Stability Depends on Multisensory Estimates of Gravity

The results rule out a general explanation that the brain depends solely on visual heuristics and assumptions about object stability and suggest that multisensory estimates of gravity govern the perceived stability of objects, resulting in objects appearing more stable when the head is tilted in the same direction in which they fall.

Gender and line size factors modulate the deviations of the subjective visual vertical induced by head tilt

The results showed that gender and line angle size have an impact on the evaluation of the SVV, and this methodological issue may explain (at least in part) the discrepancies found in the literature on the head-tilt effect.

Individual differences and impact of gender on curvature redirection thresholds

A study to investigate the role of gender on curvature redirection thresholds (RDTs) using the maximum likelihood procedure with the classical two-alternative force choice task shows high variability in individuals' R DTs, and that on average women have higher curvature RDTs than men.

Menstrual phase influences gender differences in visual dependence: A study with a computerised Rod and Frame Test

Results confirm findings of a male advantage on the RFT and indicate that menstrual cycle phase does affect gender differences in visual dependence on the CRFT; thus, caution with RFT results is recommended when female subjects are involved.

This simple test appears to be valid for the routine assessment of spatial disorders in neurological impairments and was applied to three subacute stroke patients with left hemiparesis, of whom two showed left spatial hemineglect.



Gender Differences in Perception of Self-Orientation: Software or Hardware?

Although instructions did not eliminate gender differences, internal instructions allowed females to reduce their perceptual bias in the supine orientation.

Sex differences in judging self-orientation: the morphological horizon and body pitch

It is concluded that sex differences in the perception of self-orientation are associated with gravireceptors (e.g., otoliths) and added to the literature on sex differences for spatial orientation tasks.

Superior Performance by Women in a Visual Orienting Task: A Limit on the Concept of Field Dependence

15 women and 24 men were compared on a visual orienting task requiring observers to set a luminous line to a vertical position while viewing from a laterally tilted body position. No visible frame of

Sex differences in line bisection as a function of hand

Sex differences in mental rotation and spatial rotation in a virtual environment

Properties of the internal representation of gravity inferred from spatial-direction and body-tilt estimates.

This work compared the ability of six tilted subjects to indicate earth-centric directions in the dark with a visual and an oculomotor paradigm and to estimate their body tilt relative to gravity, and proposes that basically similar computational mechanisms, working with different settings, may be responsible.

The subjective visual vertical and the perceptual upright

The OCHART technique provides a new, simple and readily applicable method for investigating the PU which complements the SVV, and is the first time that maximum likelihood estimation has been demonstrated in combining information between different reference frames.
