The objectives of this study were (a) to determine the impact of a spouse monitoring procedure on the target's (husband's) behavior and the recorder (wife's) view of the marriage and (b) to assess the relationship between the target's positive behaviors and the recorder's marital satisfaction rating. In one condition, husbands were informed that their behavior was being observed, whereas in a comparison group, husbands were kept unaware of the observation procedure. In both conditions, wives kept daily recordings of (a) positive behaviors emitted by their husbands and (b) perceptions of their marital relationships. No differences were found in rates of husbands' behavior or in wives' perceptions of their marriages as a function of the awareness manipulation. Analyses examining the relationship between spouse behavior and daily satisfaction ratings indicated a statistically reliable association, although the majority of variance in satisfaction ratings was attributable to unique subject variables.This article is based on a thesis submitted by the first author to the Department of Psychology of the University of Pittsburgh. The described research was supported in part by a Faculty Research Grant from the University of Pittsburgh awarded to the second author. 相似文献

The hypothesis is tested that the response to dextroamphetamine in terms of activity, attention, impulsivity, and autonomic activity is similar in normal (N) and hyperactive (H) children. Fourteen N and 15 H boys had skin conductance (SC), heart rate (HR), and finger temperature (ST) recorded during rest, presentation of eight 75- dB tones, and a reaction time (RT) procedure on three occasions: off drug (Day 1) and after ingestion (double-blind) of placebo and of .5 mg/kg dextroamphetamine. Both N and H groups showed drug effects, compared to placebo, of reduced motor activity and impulsivity, improved attention (RT), increased HR and HR slowing during RT foreperiods, and decreased ST. Both groups also had decreases in SC responsivity but in different parts of the test. Placebo compared to Day 1 produced increased activity and autonomic arousal but no change in RT. Stimulant drugs thus have similar behavioral and autonomic effects in both N and H boys, but the beneficial effects on behavior do not depend critically on increases in arousal. 相似文献

Human “Yes-No” signal-detection performance was tested under a modified perceptual-defense procedure. A majority of Ss tended to match the relative frequency with which they gave affirmative responses to the relative frequency at which signals were presented. These Ss thereby replicated the “probability-matching” behavior found in previous signal-detection and discrimination studies. However, in marked contrast to those previous results, another large set of Ss showed a tendency toward preponderant use of one of the two responses (typically, of “No”) rather than toward probability-matching. The evidence failed to suggest that the latter effect was related to a lesser ability to make the requisite sensory discrimination or to response inhibition induced by taboo stimuli. 相似文献

Ss who are exposed to a sound coming from straight ahead, but who turn their eyes 20 deg to the side toward a visible speaker during the exposure period and expect to hear the sound coming from the visible source, show a shift in localization of the sound up to a maximum of about 9 deg. Ss who only turn their eyes 20 deg to the side during the exposure period show a smaller but significant shift in sound localization, while Ss who do not turn their eyes, but are led to expect that the sound will appear to come from a visible loudspeaker 20 deg to the side, show no significant shift. Comparison of test results before and after the exposure period, with eyes directed straight ahead and no visible speaker present, shows the presence of a localization aftereffect for those experimental groups that showed a significant localization shift during the exposure period. Sounds are localized a few degrees to the side of their physical location in the same direction as the shift in localization during the exposure period. Further experiments show that part, but not all, of the shift in localization during the exposure period can be understood in terms of a shift in perceived head direction. The localization aftereffects are shown not to be due to change in physical or perceived eye or head position. 相似文献

Recently Markov learning models with two unidentifiable presolution success states, an error state, and an absorbing learned state, have been suggested to handle certain aspects of data better than the three state Markov models of the General All or None model type. In attempting to interpret psychologically, and evaluate statistically the adequacy of various classes of Markov models, a knowledge of the relationship between the classes of models would be helpful. This paper considers some aspects of the relationship between the class of General All or None models and the class of Stationary Absorbing Markov models withN error states, andM presolution success states. 相似文献

The issue of academic freedom for students is frequently a source of heated controversy. In the emotionally charged atmosphere that surrounds this question the true nature and purpose of academic freedom are too often obscured. This discussion focuses attention on the philosophical and educational premises that underlie this concept and attempts to examine it from several frames of reference. A brief summary tracing the historical evolution of academic freedom for students to the present is developed and 8 common points of emphasis as interpreted from several current statements on the subject are outlined. An additional concern of some moment involving the relationship and responsibility of the college student personnel worker to these 8 significant points of common emphasis is noted. 相似文献

Effect of prior Pavlovian discrimination training upon learning an operant discrimination 总被引:1,自引:1,他引:0 下载免费PDF全文
The effect of Pavlovian discrimination training with two stimuli upon subsequent learning of an operant discrimination involving those stimuli was studied. After preliminary lever press training, the lever was removed and thirsty rats received noncontingent pairings between S1 (a tone or a clicker) and water reinforcements, whereas S2 (a clicker or a tone) occurred always without reinforcement. This procedure presumably established S1 as a positive CS for respondent behavior, whereas S2 was established as an inhibitory CS. Following this training, the lever was reintroduced and the rats were trained on an operant (lever pressing) discrimination involving S1 and S2. For the Consistent Ss, S1 was the SD and S2 the SΔ in the operant discrimination; for the Reversed Ss, S2 served as SD and S1 as SΔ. The Consistent Ss learned the operant discrimination significantly faster than did the Reversed Ss. The result emphasizes the importance of respondents, conditioned to SD and SΔ, which modulate operant performance to these stimuli. 相似文献
