Task specificity determines the most significant changes in cerebral blood flow in different mental rotation paradigms.
One of the most extensively researched types of image transformation is that of mental rotation, a paradigm first established by Shepard and Metzler (1971).
Mental rotation, a classic experimental paradigm of cognitive psychology, tests the capacity of humans to mentally rotate a seen object to decide if it matches a target object.
Positron emission tomography (PET) was used to observe changes in regional cerebral blood flow (rCBF) in 10 right-handed healthy volunteers performing two paradigms of mental rotation.
CSH in transwomen seems to have little effects on memory function [ 47] though it may, e.g., affect activation patters in fMRI paradigms including mental rotation tasks [ 48].
The mental-rotation task is a well known research paradigm to examine cognitive processes of mental imaging and mental manipulation (Shepard & Metzler, 1971).
For each mouse, the OKR was recorded before and >24 hours after drug exposure using the standard 30 seconds on/30 seconds off OKR stimulus paradigm (Figure 2) with alternating clockwise and counterclockwise rotation.
Shepard and Metzler paradigm [ 1] was used for the investigation of mental rotation performance.
Huang et al. (2011) also used a similar paradigm to Experiment 3 to show that practicing in an "opposite" visuomotor rotation could lead to savings (faster re-learning) if the hand-direction was the same (due to model-free learning).
In order to test how different target types could best be combined into a single paradigm, we also compared a blocked and a mixed variant of the mental rotation task.
