Recent advances in microcomputer technology make it possible to monitor the internal state of the human operator in exotic environments with an ease and accuracy not imagined 10 years ago. It is now economically and technically feasible for many psychophysiologists to move out of the laboratory and apply their expertise to real-world problems. Two applications of psycho physiological methods to the study of pilot workload are described, one in simulated flight and one in actual flight. 相似文献

Previous research indicates that children from violent marriages are more likely to suffer from conduct problems and/or anxiety disorders than children from nonviolent, satisfactory marriages. However, knowledge regarding specific factors present in violent marriages relating to child problems is limited. The present study examined the relationships involving interspousal aggression, parent-child aggression, and child behavior problems in a sample of 45 children from maritally violent families. Mothers indicated how often their children witnessed interspousal aggression and were victims of parent-child aggression. Mothers also rated their children's problem behaviors while children reported on their own depressive symptoms. The witnessing of interspousal aggression was highly associated with parental aggression directed toward children. Parent-child aggression related to attention problems, anxiety-withdrawl, motor excess, and conduct problems in children. However, the witnessing of interspousal aggression was not significantly related to child behavior problems. These results are consistent with theoretical predictions linking marital problems to child behavior by virtue of their association with parenting.This research was supported in part by a Grant-in-Aid of Research awarded to the first author by Sigma Xi, the Scientific Research Society, and NIMH Grant No. MH35340 awarded to the third author.

A revised version of the Rescorla-Wagner (1972) mathematical model is presented. A metatheoretical assumption of an attentional process, the added revision, is conceived as an independent α-salience growth factor determining both rate of association and performance. Conditioned stimulus-unconditioned stimulus (CS-US) correlation, and CS-US interval (two primary conditioning parameters) are incorporated in the mathematical model as α-salience growth rate and as α-salience and association asymptote factors, respectively. In this manner, the long-standing issue of necessary and sufficient factors in classical conditioning is resolved. An empirical assessment of the model’s parameters has been included. 相似文献

The odd-even status of a sum depends on the odd-even status of its addends. A sum must be odd if an odd number of its addends are odd; else it must be even. A proposed sum that violates the required odd-even status of the sum—that is, deviates from the correct sum, whether odd or even, by an odd value (e.g., splits of ±1, ±3, ±5)—can be rejected immediately as false. Subjects in the present study did indeed use the odd-even rule in sum verification, because they were as fast and accurate in rejecting a split of ±1 as one of ±2, and a split of ±3 as one of ±4, even though a larger split generally is easier to reject (symbolic distance effect), and splits of ±3 and ±4 were rejected faster and more accurately than those of ±1 and ±2. Performance on separate odd-even tasks indicated that the odd-even properties of numbers and sums are readily available for use by adults, and that persons who do well on such tasks are especially likely to use the odd-even rule in sum verification. 相似文献

Tables of sequences of two-class events are presented for use in programming psychological experiments in which behavior on trial n may be a function of the events of trials n ? 1, n ? 2, and/or n ? 3. Various factors related to schedule generation are discussed, i.e., restrictions on trial-block length which accompany sequential balance, interrelationships of trial blocks in the multiblock experiment, relationships between run length and r-tuple occurrences, and alternation behavior. Following a consideration of various methods of schedule generation for the two-class experiment, it was concluded that no method can result in schedules that possess all properties considered desirable in psychological experiments. However, the present sequences allow for sequential balance and analysis, and thus should prove useful in producing schedules in some contexts that are standard with regard to sequential influences. 相似文献
