The Cognitive Failures Questionnaire (CFQ) and its correlates.

This paper describes a questionnaire measure of self-reported failures in perception, memory, and motor function. Responses to all questions tend to be positively correlated, and the whole questionnaire correlates with other recent measures of self-reported deficit in memory, absent-mindedness, or slips of action. The questionnaire is however only weakly correlated with indices of social desirability set or of neuroticism. It is significantly correlated with ratings of the respondent by his or her spouse, and accordingly does have some external significance rather than purely private opinion of the self. The score is reasonably stable over long periods, to about the same extent as traditional measures of trait rather than state. Furthermore, it has not thus far been found to change in persons exposed to life-stresses. However, it does frequently correlate with the number of current psychiatric symptoms reported by the same person on the MHQ; and in one study it has been found that CFQ predicts subsequent MHQ in persons who work at a stressful job in the interval. It does not do so in those who work in a less stressful environment. The most plausible view is that cognitive failure makes a person vulnerable to showing bad effects of stress, rather than itself resulting from stress.

Modality differences in relation to grouping in immediate recall.

An earlier study of auditory grouped presentation of digit strings had shown recall to be impaired by recalling the last group first. From this, it has been concluded that the item codes formed at Stage 1 of processing, and before conversion to a group code at Stage 2, were not yet in an output buffer. The present paper employs visual presentation for two similar studies, with results opposite to the earlier one; in a third experiment, ungrouped auditory stimulation gave results which were a compromise between those for vision and those for grouped auditory stimulation. These results suggest a use of echoic storage, over long intervals; in the visual case this is not so and an output buffer is employed.

Noise in relation to annoyance, performance, and mental health.

There are many psychological factors which cause differences of human response to the same level of sound energy. Nevertheless, experiments have allowed these factors to be understood, at least to the extent where policy decisions can be made. The results show that increasing levels of noise increase annoyance, probably increasing the general arousal or excitability of the nervous system. This gives changes in performance which are sometimes detrimental, but not by any means always. Annoyance is associated with psychiatric ill-health, but increases in noise do not appear to increase the proportion of people with such illness.

Language and ergonomics.

The instructions for operating or maintaining a machine may be just as important for the user as the design of the machine itself. One way of phrasing the same instruction may be successful, and another not. A number of hints on the best way to word instructions can be found in experiments which compare different grammatical forms.
