Criticism is leveled at attempts to develop alternative forms of the Matching Familiar Figures test when the literature suggests that what is required is a more reliable test, not simply an alternate version.
Children aged 5 to 6 years living in either a suburb of London or in a small town in Northern Ireland which has been virtually free from violence, were asked to make up stories in response to a series of pictures depicting such things as derelict houses or a train crash. More Northern Irish children mentioned bombs and explosions than did the London children. To investigate the possibility that this knowledge of explosions might be the result of at least incidental exposure to coverage of such events on Northern Irish television news a further study was initiated. Children from another relatively quiet part of Northern Ireland were compared with children from two separate areas of Scotland where television reception is only possible from Northern Ireland and from a third area in Scotland where Northern Ireland television news cannot be received. Children from those areas where Northern Irish television news can be received again outnumbered those from the control area in terms of mentions of the words bomb or explosion.
To assess the concurrent validity of the Fruit Distraction Test, the Stroop Color-Word Test and the Fruit Distraction Test were administered to two groups of boys aged 12 yr. (N = 63) and 8 yr. (N = 52). Partial correlations, with IQ controlled, based on time and error scores derived from both tests, provided no convincing evidence that the Fruit Distraction Test is a valid downward extension of the Stroop.

Isolated Acetabularia nuclei were microinjected with Tobacco Mosaic Virus RNA and then implanted into an anucleate posterior fragment of an Acetabularia cell. Injected RNA was translated in the Acetabularia cytoplasm from the first to twelfth day after implantation of the nuclei. The production of specific virus proteins was detected and localized in the Acetabularia cytoplasm by an immunofluorescence precipitation technique.
Isolated Acetabularia crenulata nuclei were injected with Mengo virus RNA solution and then implanted into anucleate posterior Acetabularia mediterranea cell fragments or fused with Acetabularia ryukyuensis cytoplasts. The injected animal virus RNA was actively translated in the plant cell cytoplasm. Mengo virus proteins were detected and localized in Acetabularia cytoplasts by use of an immunofluorescence method on the first to fifth day after injection.
14 reflective and 14 impulsive boys performed tactual matching tasks in which frequency of observation of the standard was manipulated by successive or simultaneous presentation and in which stimulus features were controlled so that the amount of stimulus analysis carried out might be inferred. The results suggest that an impulsive performance was improved by simultaneous presentation of the stimuli but even in this condition the impulsive subjects did not carry out an adequate amount of stimulus analysis.
