Subliminal Perception: The Nature of a Controversy
Preconscious processing in schizophrenics: An exploratory investigation
Extraction of information from continuously masked successive stimuli: An exploratory study
Results from this series of brief pilot experiments suggest that, under certain conditions, it is humanly possible to extract information from superimposed continuously masked letter strings presented successively on the VDU of a microprocessor
The Attenuation of Visual Persistence
Haber & Standing (1969, 1970) have shown that visual persistence (VP), which it is suggested corresponds to Sperling's ‘Visual Information Store’, can be directly measured. The present investigation extends this approach with another direct measure of VP. This involves recording the number of phenomenally simultaneous lines that are experienced when viewing a single trace moving in a straight line, at a sweep speed above the fusion threshold, acr…
A Note on Field Dependency and Movement After‐effects
Eeg Correlates of Threshold Regulation as a Function of Stimulus Wavelength: A Comparison Between Normal Subjects and Psychiatric Patients
Results of a previous study (Dixon & Lear, 1963, 1964) suggested the perceptual defence effect may be attributable to changes in pre‐awareness levels of cortical activation. The present study looks into this apparent relation between threshold and activation by making use of the fact that the direction of threshold change, under conditions of sympathetic activity, appears to depend upon the wavelength of the stimulus test light. The results, usin…
Influences of Training and Fatigue on the Continuous Recording of a Visual Differential Threshold
A visual differential threshold was recorded continuously for 14 min. in each of six different sessions. Integrated scores for 1/2‐min. periods, indicative of mean threshold values, showed a marked tendency to rise between the second and the tenth minute of the experiment. This was attributed to a fatigue decrement of a central state of vigilance or alertness. The scoring of length of curve and number of control adjustments during 1/2 min. period…
