Mental rotation and sexual orientation
Mental rotation, a type of visuo-spatial ability, is the ability to imagine a figure rotating in space without verbal mediation. Gender differences in the performance of mental rotation tasks are well documented but the relationship between sexual orientation and mental rotation is uncertain. This …

CHILDREN'S MENTAL ROTATION: COMPETENCE AND PROCESS.
… primarily through two perspectives: the developmental and the information processing orientations. This research combines these approaches. Mental rotation (the ability to mentally rotate objects) was examined by focusing on the developmentalists' concern for age of acquisition of this ability …

The coloured cube test and the coloured mental rotation test: two new measures of spatial ability and mental rotation
This research introduces two new measures of mental rotation (MR) for 4- to 11-year-old children. Instead of the complex achromatic three-dimensional (3D) cube aggregates used with adults (Shepard & Metzler, 1971), or the flat two-dimensional animals used with children (Quaiser-Pohl, 2003), the new …

The Role of Stereotype Threat in Mental Rotation
<p>Numerous studies have been conducted on mental rotation ability in both males and females. A lot of the literature discusses male superiority in mental rotation task as opposed to females. This paper examined the role of stereotype threat in a mental rotation task. Particularly, the research …

A Biologically Plausible Neuron Model of Mental Rotation
… presents a biologically plausible account of mental rotation. To this end, there is evidence that mental rotation is a spatial imagery task that can invoke a variety of strategies, depending on the nature of the stimuli. This thesis uses simple but unfamiliar stimuli, which engenders a …

Mental Rotation: Can Familiarity Alleviate the Effects of Complex Backgrounds?
… the effects of complex backgrounds on mental rotation. Stimulus familiarity and background familiarity were manipulated. It systematically explored how familiarizing participants to objects and complex backgrounds affects their performance on a mental rotation task involving complex …

Mental rotation with and without a concurrent task: moderating effects of visuospatial ability
… on a battery of visuospatial tests (Card Rotations, Mental Rotations, Minnesota Paper Form Board), performed a computer-administered task requiring the mental rotation of abstract geometric shapes presented sequentially, either alone or with a concurrent task of repeating sets of six …

Differences in Performance in Mental Rotation and Short-Term Free Recall in Gender Minorities
<p>The study examined mental rotation, short-term free recall, state anxiety, and gender expression through masculinity and femininity. This study addressed gaps in literature examining gender differences in gender minority groups by investigating gender differences in two tasks: mental rotation …

Sex Differences on a Mental Rotation Task: Variations in Hemispheric Activation Between Children and College Students
… Particularly, males usually perform better on mental rotation tasks than do females. One argument for these differences is that experience with spatial activity drives these differences, such that traditionally more masculine activities require more practice of spatial abilities. Another …

The Effects of Age and Sex on Mental Rotation Performance, Verbal Performance, and Brain Electrical Activity
… a computerized 2-dimensional Gingerbread Man mental rotation task, a computerized 2-dimensional Alphanumeric mental rotation task, a computerized 3-dimensional Basketball Player mental rotation task, and a computerized Lexical Decision-Making task. Additionally, participants completed a …

An Investigation of the Relationships Between the Angle of Mental Rotation Required For Spatial Orientation, Response Times, and Accuracy
… the relationship between the angles of mental rotation when attempting to spatially orientate and the resulting response times and levels of accuracy. By means of a computer program, participants were presented with 64 mental rotational trials. The mental rotational trials consisted of a …

About turn:neural mechanisms underlying visual processing of rotated letters and digits
… related to character disorientation, implying mental rotation of the characters to the upright, while judging whether they are letters or digits (categorisation task) elicits RTs related nonlinearly to disorientation, combining both linear and quadratic component, but not indicative of mental …

Visual-Spatial & Visual-Motor Function in Pediatric Heart Transplant Recipients
… tasks - a Block Design Matching task and a Mental Rotation task. The children who received a heart transplant achieved significantly lower scores than the nonclinical children on all three visual-motor measures and all three visual-spatial measures. However, based on the tests’ norms, their …

The relationship between gonadal hormones and neurocognitive functioning in healthy men and women and patients with schizophrenia
… sexually dimorphic cognitive battery (comprising mental rotation, modified judgement of line orientation, computerized Benton judgement of line orientation, cognitive inhibition, letter and category fluency tasks, and a working memory task) in a group of healthy men (n= 42) and women (n = 42). The …

UNDERSTANDING THE STRUCTURE AND CORRELATES OF NON-RIGID SPATIAL SKILLS
… with existing measures of spatial skill (mental rotation, paper folding, bending). However, we did not find support for a continuum of spatial skills from non-rigid to rigid using a simultaneous regression and a confirmatory factor analytic approach. Finally, we replicated prior work …

Spatial Skills Activities in the Middle School Mathematics Teachers' Toolkit: The Impact of Spatial Skill Activities on Mathematical Thinking
… hands-on spatial skill problems that required mental rotation and spatial visualization to solve. While there have been many studies linking spatial skill to success in mathematics, there are few studies that attempt to establish a relationship through intervention in a middle school classroom. …

Auditory Stimulation and Its Effect on Spatial Temporal Ability
… processing, while the Vandenberg and Kuse Mental Rotation Test is a test of spatial visualization, not confounded with analytical processing. Neither of the two tests displayed a significant treatment effect, lending to the possibility that the enhancement of performance seen previously on …

Reference Frames in Human Sensory, Motor, and Cognitive Processing
… the brain uses reference-frames remains a fundamental question. The goal of this dissertation is to reach a better understanding of reference-frames in human perceptual, motor, and cognitive processing. In the first project, we study reference-frames in perception and develop a model to explain …
