The aim of this investigation was to gauge the comparative research performance of university departments of psychology in Britain. The performance indicator was the number of publications per departmental staff member in the journals of the British Psychological Society (BPS) during the seven-year period 1983–1989. The contents of these journals were thoroughly searched, and articles written by members of university psychology departments in Britain were counted. The number of publications of each psychology department was divided by the size of the department in the corresponding year and the resulting annual figures were summed to determine the number of publications in BPS journals per departmental staff member over the seven-year period. These research performance figures correlated significantly with an earlier measure of departmental research performance based on publications in the seven European psychological journals with the highest citations per published article and with recent performance indicators based on other criteria  相似文献

This study examined whether men use more eflective means of coping with dysphoria on their own than do women. Forty-four male and female college students who reported feeling dysphoric were evaluated on their coping styles at three intervals in a six and a half week time span. The findings suggest that men and women do not use significantly different appraisal and coping techniques. For both sexes, problem-focused coping was associated with less dysphoria over time, whereas emotion-focused coping was associated with more dysphoria over time. Keeping anger in was associated with more dysphoria over time for women. In addition, the way in which the situation was appraised influenced the level of dysphoria over time for both sexes.  相似文献

The multiple-baseline across responses design was used to assess the effectiveness of a belief-modification treatment package to alter the intensity of three delusional beliefs of a chronically mentally ill inpatient. Results revealed reductions in belief intensity to zero levels for all three beliefs. Generalization effects were obtained for an individualized interview and psychiatric rating scale. These results were maintained through a 6-month follow-up period.  相似文献

“攻击性行为”社会认知的实验研究   总被引:29,自引:3,他引:26  
采用两种不同的方法对人类“攻击性行为”社会认知的某些特点进行探索。结果表明:①再认过程中,被试对被攻击者的辨别率(A')明显高于攻击者,B″也具有明显特征。证明人类的外显记忆更多倾向记忆“灾难现象”。②偏好测试中,被试偏好攻击者明显多于被攻击者。证实了“攻击性行为”社会认知实验性分离的存在。也就是说学习攻击性图片在人类记忆中,产生了“攻击性行为”社会认知的启动效应。同时也证实了内隐与外显记忆之间存在任务分离的加工演变过程。③偏好测试中出现被试对陌生人(中性人物)的偏好率明显高于攻击与被攻击者的总和。我们认为这是间接启动效应,是外显记忆和内隐记忆在选择上发生冲突继而导致倾向一致的结果。  相似文献

The Kagan Matching Familiar Figures Test of Impulsivity/Reflectivity was modified to allow computer control of stimulus presentation and data acquisition via IBM-compatible systems. The comparability of computer administration and traditional hand administration was examined in a split-half study with a sample of 58 students (ages, 18–39 years). Analyses of variance revealed no significant differences between the administration techniques for latency and a small but significant difference for accuracy. Correlations between the two administration techniques were .61 for latency and .40 for error scores. Internal consistency coefficients for computer administration exceeded those for hand administration on both latency and accuracy. These data compare favorably with results reported by others and suggest that computer administration offers a viable alternative to traditional hand administration of the MFFT in research applications.  相似文献

Perception of voicing for stop consonants in consonant-vowel syllables can be affected by the duration of the following vowel so that longer vowels lead to more “voiced” responses. On the basis of several experiments, Green, Stevens, and Kuhl (1994) concluded that continuity of fundamental frequency (f0), but not continuity of formant structure, determined the effective length of the following vowel. In an extension of those efforts, we found here that both effects were critically dependent on particular f 0s and formant values. First, discontinuity inf0 does not necessarily preclude the vowel length effect because the effect maintains whenf0 changes from 200 to 100 Hz, and 200-Hz partials extend continuously through test syllables. Second, spectral discontinuity does preclude the vowel length effect when formant changes result in a spectral peak shifting to another harmonic. The results indicate that the effectiveness of stimulus changes for sustaining or diminishing the vowel length effect depends critically on particulars of spectral composition.  相似文献

Search for odd-one-out feature targets takes longer when the target can be present in one of several dimensions as opposed to only one dimension (Müller, Heller, & Ziegler, 1995; Treisman, 1988). Müller et al. attributed this cost to the need to discern the target dimension. They proposed adimension-weighting account, in which master map units compute, in parallel, the weighted sum of dimension-specific saliency signals. If the target dimension is known in advance, signals from that dimension are amplified. But if the target dimension is unknown, it is determined in a process that shifts weight from the nontarget to the target dimension. The weight pattern thus generated persists across trials, producing intertrial facilitation for a target (trialn+1) dimensionally identical to the preceding target (trialn). In the present study, we employed a set of new tasks in order to reexamine and extend this account. Targets were defined along two possible dimensions (color or orientation) and could take on one of two feature values (e.g., red or blue). Experiments 1 and 2 required absent/present and color/orientation discrimination of a single target, respectively. They showed that (1) both tasks involveweight shifting, though (explicitly) discerning the dimension of a target requires some process additional to simply detecting its presence; and (2) the intertrial facilitation is indeed (largely) dimension specific rather than feature specific in nature. In Experiment 3, the task was to count the number of targets in a display (either three or four), which could be either dimensionally the same (all color or all orientation) or mixed (some color and some orientation). As predicted by the dimension-weighting account, enumerating four targets all defined within the same dimension was faster than counting three such targets or mixed targets defined in two dimensions.  相似文献

Although proposed as an explanation for increases in positive and decreases in negative affect, little evidence supports the notion of a stronger efficacy-affect relationship as acute aerobic exercise intensity increases. Relationships between self-efficacy (SE), positive affect (PA), and negative affect (NA) were examined with respect to 3 randomly assigned conditions: (a) no exercise (control), (b) cycling at 55% VO2max, and (c) cycling at 70% VO2max. Twenty subjects (age = 22.6 years; M VO2max= 47.8 ml · kg−1· min−1) participated in each. Preexercise SE predicted in-task NA and postexercise PA in the 55% condition and postexercise PA in the 70% condition ( ps < .05). Although SE significantly increased from pre- to postexercise, in-task affect failed to predict these increases in SE. These data suggest that in a fit college-aged population, a stronger reciprocal relationship between preexercise SE, in-task affect, and postexercise SE does not exist with increasing levels of exercise intensity. Contrary to self-efficacy theory, no evidence was found for a reciprocal relationship. However, the relationship between efficacy and affect was such that when collapsed across conditions and time, subjects with higher SE scores reported lower NA ( p < .05).  相似文献

This study investigated the relationship between frequency of intrusive thoughts and susceptibility to reminiscent stimuli and consequent distress in parents of children with cancer and parents with healthy children. Cancer-related words embedded in the Stroop task (e.g., “chemo” printed in green ink), served as the reminiscent stimuli. Results indicated that frequency of intrusive thoughts reported 2 months before the experimental session was positively correlated with evoked thoughts and associated distress among parents with ill children. Intrusive thoughts predicted 11–17% of the variance in evoked thoughts and in elicited distress, whereas other symptoms of chronic stress did not predict evoked thoughts and elicited distress. Cognitive and affective task reactivity by parents of children with cancer were not accompanied by behavioral or physiological reactivity. Future research should examine the extent to which more acute and naturalistic intrusive thoughts elicit reactivity across cognitive, affective, behavioral, and physiological dimensions, and long-term physical and mental health effects associated with chronic intrusive thoughts.  相似文献
