SVENSON, O. Changing the structure of intuitive estimates of time-savings. Scand. J. Psychol. , 1971, 12, 131–134.–Estimates of time saved when increasing an original assumed mean speed to a higher one were collected for different distances and combinations of velocities. Following each answer in five learning phases one group of subjects was given information about the correct time-gain. A control group taking part only in the ten test phases of the experiment gave estimates systematically differing from real time-gains following a previously suggested relation. The estimates given by the experimental group were improved to the same degree as the control group's estimates were gradually better approximated by the previously found relation. 相似文献

The special case of purely qualitative multidimensional similarity was studied in four experiments concerned with simple geometric figures. A previously proposed equation did not describe the relation between subjective similarity and angular separation of the percept vectors. Factor analyses indicate that in the 'homogeneous' experiments (with parallelogram figures) there were two pairs of inversely related subjective attributes which vary as a function of the difference between the horizontal and vertical axes of the parallelogram, and that in the 'heterogeneous' experiments (different figures) there were four main independent subjective attributes. 相似文献

Ten children, 9–11 years old, solved all subtraction problems in the form of M?N=…, where 0 ? M ? 13, 0 ? N ? 13 and M ? N. The solution times were analysed and used for the formulation of a process model for subtraction. The model involves memory processes on two different levels, called reproductive and reconstructive respectively. When M=N, N=1, and M=2N the answers were quickly retrieved in reproductive memory processes. The reconstructive processes were found to be analogous to one of two counting procedures, viz. counting up and counting down. In general, the counting process starts either on N (when M < 2N) and counts up to reach the answer, or on M (when M > 2N) and counts down to reach the answer. This may reflect an effort to minimize the number of steps to be counted. However, when M > 10 and N < 10 a problem is always solved in a decrementing counting process. When M=10 many subtractions are solved in a reproductive memory process and the number 10 is also important as a point of reference for solving subtractions when M > 10 and N < 10. 相似文献
