Examines the interrelationships of task performances and developmental changes of 4-, 6-, and 8-year-olds. Significant developmental changes were observed on transposition, cue interference, and spatial memory. The pattern of intercorrelations between tasks suggested a high degree of correspondence across tasks. (ST)

Describes performance characteristics of students in an agriculture education program for which no formal qualifications are stressed. (PS)

Institutionalized mentally retarded children performed on a two-choice discrimination task under one of six conditions of reward. One indication of the results was that response-contingent non-consumable rewards were not more distracting than response-contingent consumable rewards. (Author/KM)

Analysis indicates that both 5 and 7-year-old children are capable of distinguishing between anomalous and meaningful sentences although 7-year-olds demonstrate greater awareness of selection restriction rules. (Authors)

Although subjects were able to adapt to loud noise and other stressors in laboratory experiments, they clearly demonstrated adverse aftereffects. (DM)

The Zeigarnik effect, that is, the greater recall of incompleted over completed tasks was found to be significantly more frequent in Ss of high than low resultant achievement motivation, but no difference was found between repressors and sensitizers in this effect. (Authors)

The purpose of this study was to contribute new information on the effect of stimulus presentation variables on sight-reading errors, in the hope that it might aid the development of more effective and efficient instructional designs. (Author)

Study attempts to examine the way in which the introduction of an environmental variable, in this case music, affects different indicators of vigilance performance. (Author/RK)

High school students were hired to work on a door-to-door selling task, so designed that delaying a sale produced a larger sales commission. Subjects who recognized and selected a delayed strategy in the task shifted toward a preference for delaying reward. (Authors)

Results were interpreted as showing that the superior selective listening performace of older children is due not to a greater ability to filter out distracting material at an early stage of processing, but in large part to an ability to inhibit intrusions from the distracting material during the selection task. (Author)

The specific hypothesis tested by this research is that children are able to attend to multiple cues simultaneously and are able to use the information contained in these cues. (Author)

The associations from phoneme to grapheme appeared to be considerably easier than the associations from grapheme to phoneme. (Authors)
