Examples of fixation

• This basic structural assumption implies that the difficulty of processing the current word can have no influence on the following fixation.

• During the recording, the animals were trained to maintain fixation on a central 0.2-deg blue spot.

• However, cats never hesitated to approach the fixation target when the peripheral target was in the affected region of the hemifield.

• Removal of the fixation point signaled the beginning of a trial.

• However, both the problem of fixation and that of the influence of the light-darkness contrast were now resolved.

• The sectors were 2-deg wide at their center, and their centers fell at a constant eccentricity of 5 deg from the fixation point.

• These hypotheses will be tested as additional genomic, biochemical and geological evidence sheds more light on the evolution of nitrogen fixation, photosynthesis and cyanobacteria.

• The sound presentation of the experimental instruction that required pointing was delayed until the third experimenter confirmed that accurate cross fixation had been obtained.
