Acute stress has been found to have negative and implementation intentions (IIs) to have positive effects on cognitive performance. This study was the first to examine the effects of IIs on executive action control under acute psychosocial stress. Forty-two male subjects aged 21-39 years were randomly assigned to the Trier Social Stress Test (TSST) versus a rest condition. In addition, the instruction to the executive task (a go no-go task) was manipulated (IIs versus standard instruction). After the stress test, a dual-task procedure including a go no-go task was conducted. The TSST resulted in increases in cortisol response, heart rate and state anxiety compared to the rest condition. Acute stress significantly impaired go no-go performance, but only in the group without IIs. We conclude that under acute stress conditions executive functioning is reduced, but the use of IIs can be an effective strategy to overcome this negative effect. 相似文献

Insects, birds, and mammals have been shown capable of encoding spatial information in memory using multiple strategies or
frames of reference simultaneously. These strategies include orientation to a goal-specific cue or beacon, to the position
of the goal in an array of local landmarks, or to its position in the array of distant landmarks, also known as the global
frame of reference. From previous experiments, it appears that birds and mammals that scatter hoard rely primarily on a global
frame of reference, but this generalization depends on evidence from only a few species. Here we examined spatial memory in
a previously unstudied scatter hoarder, the southern flying squirrel. We dissociated the relative weighting of three potential
spatial strategies (beacon, global, or relative array strategy) with three probe tests: transposition of beacon and the rotation
or the expansion of the array. The squirrels’ choices were consistent with a spatial averaging strategy, where they chose
the location dictated by at least two of the three strategies, rather than using a single preferred frame of reference. This
adaptive and flexible heuristic has not been previously described in animal orientation studies, yet it may be a common solution
to the universal problem of encoding and recalling spatial locations in an ephemeral physical landscape. 相似文献

Empirical evidence for a functional role of syllables in visual word processing is abundant, however it remains rather heterogeneous.
The present study aims to further specify the role of syllables and the cognitive accessibility of syllabic information in
word processing. The first experiment compared performance across naming and lexical decision tasks by manipulating the number
of syllables in words and non-words. Results showed a syllable number effect in both the naming task and the lexical decision
task. The second experiment introduced a stimulus set consisting of isolated syllabic and non-syllabic trigrams. Syllable
frequency was manipulated in a naming and in a decision task requiring participants to decide on the syllabic status of letter
strings. Results showed faster responses for syllables than for non-syllables in both tasks. Syllable frequency effects were
observed in the decision task. In summary, the results from these manipulations of different types of syllable information
confirm an important role of syllabic units in both recognition and production. 相似文献

This study presents the results of an analysis of pragmatic aspects of language samples obtained from five agrammatic aphasic individuals prior to and following Linguistic Specific Treatment (LST). Clinically and statistically significant positive changes in informativeness and efficiency were documented in posttreatment samples. Analysis of communicative competence (i.e., na?ve listeners' ratings of pre- and posttreatment audiotaped samples), was undertaken to examine the social validity of quantified changes. Mean ratings across listeners were computed to evaluate their subjective perceptions of general communicative constructs. Results indicated that objectively measured changes in pragmatic aspects were perceptible to na?ve listeners, however, to varying degrees across participants and constructs. 相似文献

Political skill is a social effectiveness construct with a demonstrated capacity to predict job performance. However, because performance prediction research in this area to date has made exclusive use of self‐reports of political skill, and due to frequent distrust of self‐ratings of constructs in important personnel decisions, there is a need to investigate how multiple alternative sources of political skill and job performance measures relate, thus raising both theoretical and methodological issues. In three studies, employing a triadic data collection methodology, and utilising both cross‐sectional and longitudinal designs, this research tested the hypotheses that employee political skill, measured from the perspective of employees' assessor A, will positively predict job performance rated by assessor B (i.e. Hypothesis 1a), and vice versa, that employee political skill measured by assessor B will predict job performance ratings measured by assessor A (i.e. Hypothesis 1b). 相似文献

The present study investigated the effects of an acquaintance-rape prevention program on college students' attitudes toward rape and attitudes toward women, perceptions of acquaintance-rape scenarios, and rape empathy. Participants were led to believe that they were participating in two separate experiments in order to decrease demand characteristics. Results indicated that intervention group men and women became more empathic toward the victim than the control group, postintervention. Within the intervention group, men changed more in their attitudes toward women postintervention than did women. In addition to positive attitude change, results with the date-rape scenarios suggested that intervention-group men became more certain of their definitions of rape situations postintervention. Prior to the intervention, women were generally more certain of their definitions than were men, with intervention-group men approximating women's responses postintervention. 相似文献

On countertransference enactments 总被引:2,自引:0,他引:2
T J Jacobs 《Journal of the American Psychoanalytic Association》1986,34(2):289-307
This communication focuses on the relation of countertransference to psychoanalytic technique, calling attention not to the more obvious forms of countertransference that have been commented on by previous writers on the subject, but to its subtler ones. Often well camouflaged within the framework of traditional, time-tested techniques, this aspect of countertransference may attach itself to our way of listening and thinking about patients, to our efforts at interpretation, to the process of working through, or to the complex issue of termination. Less recognizable than its more boisterous counterpart and in some respects less tangible, this side of the problem of countertransference is no less important. For it is precisely those subtle, often scarcely visible countertransference reactions, so easily rationalized as parts of our standard operating procedures and so easily overlooked, that may in the end have the greatest impact on our analytic work. 相似文献

EMG biofeedback training, relaxation training, and placebo for the relief of chronic back pain 总被引:5,自引:0,他引:5
24 patients with chronic low back pain were randomly assigned to three treatment conditions: EMG biofeedback, relaxation training, and a placebo condition. Patients were seen for eight sessions and were evaluated before Session 1 and after Session 8. Eight analyses of covariance which were adjusted for age and pretest scores were computed on the final scores to find which variables could detect significant difference between treatments. Age was included as a covariate because the differences in age between conditions were significant. Four variables with significant and nearly significant differences were chosen for analysis. The second set of analyses identified the nature of the differences among the three conditions. These included a priori planned comparisons among conditions, and paired t tests. Relaxation-trained subjects were significantly superior to subjects in the placebo condition, in decreasing pain during the function test, increasing relaxation, and decreasing Upper Trapezius EMG. They were superior to EMG Biofeedback training in increasing reported activity. Both Relaxation and EMG trained subjects were able to reduce Upper Trapezius EMG by Session 8. Relaxation-trained subjects showed significant change on eight of the 14 possible comparisons for each treatment condition. EMG biofeedback training showed significant favorable results in only one condition; the placebo condition showed no significant results. Relaxation training gave better results in reducing EMG and pain, and in increasing relaxation and activity than either EMG biofeedback alone or a placebo condition. 相似文献

This paper considers leading ideas of Albert Ellis on psychological theory and therapy in relation to ideas of the celebrated philosopher, Karl Popper. The aim is to indicate striking similarities in their views on learning, the genesis of emotional disturbance and, in particular, rationality. Discussion commences with Popper's early, and little studied, work on psychology. His philosophy of science is then surveyed along with the theory of rationality that he analogically extends from it. After tracing the evolution of Ellis' thought, we note the central roles he assigns to irrational thinking in explaining emotional disturbance and to rational thinking in its treatment. Different senses of rationality are distinguished in his work, one of them associated with criticism, which provides a most important similarity to Popper's view of rationality.For helpful comments on draft versions of this paper the author is indebted to Barry Butcher.Drs. Jocelyn Dunphy and Albert Ellis, and an anonymous reviewer for this journal.Studies of Popper on psychology have only begun to appear in recent years. The most detailed is (Berkson & Wettersten, 1984). 相似文献

Speech acts and arguments 总被引:2,自引:0,他引:2
Scott Jacobs 《Argumentation》1989,3(4):345-365
Speech act theory seems to provide a promising avenue for the analysis of the functional organization of argument. The theory, however, might be taken to suggest that arguments are a homogenous class of speech act with a specifiable illocutionary force and a single set of felicity conditions. This suggestion confuses the analysis of the meaning of speech act verbs with the analysis of the pragmatic structure of actual language use. Suggesting that arguments are conveyed through a homogeneous class of linguistic action overlooks the way in which the context of activity and the form of expression organize the argumentative functions performed in using language. An alternative speech act analysis would treat folk terminology as a heuristic entry point into the development of a technical analysis of the myriad argumentative functions and structures to be found in natural language use. This would lead to a thorough-going pragmatic analysis of the rational and functional design of speech acts in argumentation. 相似文献
