Several authors pointed out that left–right discrimination (LRD) tasks may be entangled with differential demands on mental rotation (MR). However, studies considering this interrelationship are rare. To differentially assess LRD of stimuli with varying additional demands on MR, we constructed and evaluated an extended version of the Bergen right–left discrimination (BRLD) test including additional subtests with inverted stickmen stimuli in 174 healthy participants (50♂, 124♀) and measured… 
The Impact of Handedness, Sex, and Cognitive Abilities on Left–Right Discrimination: A Behavioral Study
TLDR
An advantage of left-handers in both identifying left hands and in verifying “left” propositions and a negative correlation of LRD reaction time with visuo-spatial and verbal long-term memory was found independently of sex, providing new insights into the relationship between cognitive skills and performance on LRD.
Left-handers, retrained left-handers and right-handers: A comparative study
Present study was aimed at further extension of the scientific data concerning the influence of retraining in left-handers as well as concerning some disabilities ascribed to the left-handedness.
Effect of acute experimental hand pain on left–right discrimination response latency for hand recognition
TLDR
The results of this study were not consistent with previous hand left–right discrimination response latency results and may cast doubt on the attentional bias hypothesis that is currently considered to underpin response latency changes during acute experimental hand pain.
Cognitive training in an everyday-like virtual reality enhances visual-spatial memory capacities in stroke survivors with visual field defects
TLDR
It is suggested that VR training can improve particularly visual-spatial skills in patients with hemianopia or quadrantanopia, and in the patient group compared to the control group, the training particularly resulted in improved visual memory retrieval and reduced memory complaints.
Training in a comprehensive everyday-like virtual reality environment compared to computerized cognitive training for patients with depression
TLDR
Investigating whether ecological validity of computerized cognitive training could be increased by a comprehensive everyday-life-simulating training device combining virtual reality, 360°-all-around visibility and autonomous navigation motions found it did not prove a benefit of the more naturalistic training setting.
Space in Neuropsychological Assessment
In clinical practice complaints in spatial cognition are fairly common, but detailed assessment of possible disorders of space is not routinely performed. This chapter provides a brief overview of
Disturbed spatial cognitive processing of body-related stimuli in a case of a lesion to the right fusiform gyrus
TLDR
The case of a young male patient with epilepsy and a circumscribed lesion in the right FG who presented with isolated impairments in spatial cognitive processing of body-related stimuli and discusses the patient’s selective impairment from the view of current empirical and theoretical work on the segregation of functions in the FG.

Sex Differences in Left/Right Confusion
TLDR
It is concluded that self-ratings on left/right confusion questions, although they yield reliable sex differences, are poor predictors of actual performance on spatial tasks that involve left/ right judgements.
What is improved if a mental rotation task is repeated – the efficiency of memory access, or the speed of a transformation routine?
TLDR
Tests adapted to the predictions of the 3 theories revealed specific learning effects but no transfer, neither to old objects presented in new perspectives nor to new objects, which supports an instance-based explanation of practice effects which states that objects are represented in multiple perspective views.
Training generalized spatial skills
TLDR
Investigating whether intensive long-term practice leads to change that transcends stimulus and task parameters found improvement in the nonpracticed spatial task was greater than that in the VAT; thus, improvement was not merely due to greater ease with computerized testing.
Suitable stimuli to obtain (no) gender differences in the speed of cognitive processes involved in mental rotation
Gender differences in speed of perceptual comparison, of picture-plane mental rotation, and in switching costs between trials that do and do not require mental rotation, were investigated as a
TMS over the left angular gyrus impairs the ability to discriminate left from right
Mental rotation does not account for sex differences in left–right confusion
Hand dominance influences the processing of observed bodies
TLDR
A novel embodiment effect whereby the processing of a static schematic human figure is modulated by an individual's personal motor capabilities is demonstrated, suggesting that motor simulation may contribute to whole body perception in the absence of actual or implied actions.

TLDR
The functions relating RT to angular orientation were parallel across the three tasks, suggesting that S-R compatibility played no role, and that the participants mentally rotated the letters to the upright in each case.
Right-Left Discrimination in Younger and Older Children Measured with Two Tests Containing Stimuli on Different Abstraction Levels
TLDR
Two paper-and-pen tests, consisting of line drawings of human figures, viewed from the back, the front, or randomly alternating between back and front drawings, were used to study right-left discrimination in younger and older children to discuss theories of hemispheric lateralization, brain development, and cognitive development.
Right-Left Discrimination in Learning Disabled and Normal Control Boys
This study was designed to determine whether deficits in right-left discrimination persisted in a sample of older learning-disabled subjects, and whether there was a differentiation in verbal tasks
