      <title>SEARCH TASK TO ASSESS VISUAL LOBE SIZE</title>
      <link>https://trid.trb.org/View/211520</link>
      <description><![CDATA[Using a sample of 18 Cantonese Chinese subjects that covered a wide range of acuity scores and age, very high correlations were obtained between time taken on a simple card-sorting task and visual lobe dimensions.  With subjects younger than 30 years of age and having good acuity, similar but not so highly significant correlations were found.  Only one card-sorting session was required to produce useful data for between-subjects comparisons so that the card-sorting task may provide a simple, fast, and valid measure of a visual function of great importance to search performance. Also, a simple means of calculating visual lobe size from tachistoscopically presented stimulus material was tested and found to produce comparable results to those obtained using a more complex method of calculation involving data transformation.]]></description>

      <title>LIQUID CRYSTALS IN THE SERVICE OF ROAD SAFETY</title>
      <link>https://trid.trb.org/View/91940</link>
      <description><![CDATA[This article describes a device which has been developed to study the new variable signs, it is called the tachysoscope. It applies one of the properties of liquid crystals.  The author explains the method of operation and demonstrates the advantages of this apparatus. /TRRL/]]></description>

      <title>METHODS FOR THE EVALUATION OF TRAFFIC SIGNS</title>
      <link>https://trid.trb.org/View/64395</link>
      <description><![CDATA[A series of experiments was carried out to measure comprehension, or intrinsic meaning, of traffic sign symbols under a variety of conditions.  In addition, the preferences for symbolic representation of traffic sign messages were measured by determining population stereotypes, and subjective meaning of signs was measured using the semantic differential technique.  Three questionnaire techniques were developed and compared for use in measuring intrinsic meaning, preference, and clarity of symbolic messages. Learning and memory for the meanings of unfamiliar symbols was examined in two experiments.  Laboratory techniques included the measurement of glance legibility using a reltively simple tachistoscopic method, and the measurement of the speed with which subjects could extract information from signs, using a reaction time technique.  Several of these methods, with which the same series of signs was examined, were compared for their relative ability to predict results obtained in the initial on-the-road study. Conclusions and recommendations are made on the basis of this series of experiments.  /Author/]]></description>

      <title>EFFECTS OF NOVELTY AND ODDITY ON VISUAL SELECTIVE ATTENTION</title>
      <link>https://trid.trb.org/View/46551</link>
      <description><![CDATA[Effects of novelty and of oddity on selective attention were investigated through tachistoscopic recognition. When A pre-exposure field consisted of dots of one colour, letters of a different colour were more likely to be identified than letters of the same colour. In displays of 10 letters, two letters differing in colour from the remainder were more likely to be identified. Tachistoscopic exposure precluded determination of responses by eye movements, and there were controls for chromatic adaptation and other factors that might have biased the results.

      <title>STUDIES ON THE COMBINATION OF THE INFLUENCE OF ALCOHOL AND NIGHT FATIGUE</title>
      <link>https://trid.trb.org/View/39819</link>
      <description><![CDATA[In two series of tests carried out at night (at 21.00, 23.00, 1.00, 3.00 and 5.00 hrs) 38 test subjects, both sober and drunk, were tested with the D-2-test, the Beck equipment and the tachistoscope. It was found that night fatigue causes decreased efficiency, but no conclusion was able to be drawn with regard to potential efficiency decrease resulting from the influence of alcohol combined with night fatigue. /TRRL/]]></description>

      <title>ALCOHOL AND NIGHTIME FATIGUE OF DRIVERS</title>
      <link>https://trid.trb.org/View/25463</link>
      <description><![CDATA[In two night-time test series (carried out at 2100, 2300, 0100, and 0500 hrs.) 38 persons were tested by the d2 test, the Beck apparatus, and tachistoscope, in a sober and alcoholized condition. Though the night-time tiredness mainly causes clear loss in output, one cannot speak of a magnification of the loss in output as a consequence of alcohol effect and night-time tiredness.
