A series of five experiments examined the effects of irrelevant speech on proofreading and memory. Four of the experiments used a proofreading task and showed that the deleterious effects of irrelevant speech: (1) depend on the speech being meaningful, (2) are only present when the burden on short-term memory is low and (3) are manifested in a lower detection rate for non-contextual as opposed to contextual errors. Neither the spatial location of the speech (either in terms of spatial dispersion of sources or spatial movement of a single source) nor the intensity of the speech (in a range bounded by 50 dB(A) and 70 dB(A)) had any effect on proofreading. Late selection models of attention are favoured by the results in preference to models having arousal, short-term memory or early selection in attention as their basis. A final experiment showed serial recall for visual lists to be impaired by the presence of any speech-like sound (including reversed speech and speech in an unfamiliar language) which suggests a set of phenomena qualitatively different from those associated with proofreading. Throughout the article the practical consequences of the findings are emphasized. 相似文献

Typically, hearing a repeated syllable produces minimal disruption of serial recall of visual lists, but a sequence of different syllables impairs performance markedly. Two conditions for presenting anidentical sequence of three syllables are compared: one, in which, by means of stereophony, each syllable is assigned to the left, center, or right auditory locus (three streamsnot changing in state), and another, in which the same syllable sequence occurs in one location only (one streamwith changing state). Disruption was significantly less in the stereophonic than in the monophonic condition. There was a joint effect of changing state and location, not an effect of the number of locations alone. In Experiment 2, temporal predictability was used to manipulate changing state. The disruptive effect ofregular presentation of a repeated syllable was markedly increased when it was presentedirregularly. The results are discussed in the context of organizational factors in short-term memory. 相似文献

The effects of two types of perceived control were assessed for performance during and following exposure to continuous loud noise at 90 dBC. Subjects performed a tracking task during exposure and the Stroop test in the period following exposure. Control could be effected either (1) by attenuating the intensity of the noise or (2) by reducing the difficulty of the tracking task. In both cases subjects were encouraged not to exercise control. Performance in treatments involving loud (90 dBC) and soft (55 dBC) noise served as baseline conditions. Perceived control of task difficulty accentuated the tendency for root-mean-square error to rise during the tracking task. There were no significant effects of noise intensi ty on tracking performance. Loud noise reduced the incidence of errors in the Stroop test but perceived control failed to influence this effect. The results are discussed in terms of the generality of perceived control phenomena. 相似文献

AbstractIn Phaedo, Plato shows the grace of a true courage which can affirm life even in death. Socrates’ courage is not that of the martyr, grounded on a belief in divine reward; his is the courage of the philosopher who knows that he does not know. In his self-reflexive striving to be a person who strives for wisdom, Socrates dissipates the fear of death by dissolving the presumption on which this fear is based, and reframing death as an opportunity for knowledge. Socrates’ courage is therefore founded on an epistemic hope that is embodied in the very activity of philosophy. 相似文献

A novel negative priming (NP) effect is reported in which serial recall for a sequence of visually presented digits was poorer if the same sequence was presented as an irrelevant auditory sequence on the previous trial (Experiments 1 and 2). The effect was enhanced when attention was divided between the to-be-repeated auditory sequence and the concurrent to-be-remembered (TBR) sequence (Experiment 3). When the TBR sequences were also presented auditorily, NP arose only when the repeated TBR sequence was in the same voice as the previous irrelevant sequence; a voice mismatch produced positive priming (Experiment 4). The results suggest that the order of auditory events is registered preattentively and that inhibition may be applied to the acoustic transitions between irrelevant events. 相似文献

Providing social support may be more beneficial than receiving it: results from a prospective study of mortality 总被引:12,自引:0,他引:12
This study examines the relative contributions of giving versus receiving support to longevity in a sample of older married adults. Baseline indicators of giving and receiving support were used to predict mortality status over a 5-year period in the Changing Lives of Older Couples sample. Results from logistic regression analyses indicated that mortality was significantly reduced for individuals who reported providing instrumental support to friends, relatives, and neighbors, and individuals who reported providing emotional support to their spouse. Receiving support had no effect on mortality once giving support was taken into consideration. This pattern of findings was obtained after controlling for demographic, personality, health, mental health, and marital-relationship variables. These results have implications for understanding how social contact influences health and longevity. 相似文献

The present study explored the possibility that notetaking would help accuracy-minded interviewers to avoid cognitive expectation biases. Interviewers in simulated employment interviews were given bogus pre-interview expectations about their applicants and were either encouraged or not encouraged to take extensive notes. Consistent with past research on accuracy-motivated interviewers, both notetaking and non-notetaking interviewers avoided creating self-fulfilling prophecies. Of central interest, notetaking reduced the cognitive biasing effect of negative expectations on interviewers' overall impressions of their applicants, but failed to reduce cognitive bias in interviewers' evaluations of expectation-specific applicant characteristics. In conjunction with the motivation to form accurate impressions, notetaking can help to reduce the impact of erroneous pre-interview expectations in interviewer final evaluations. 相似文献

Hoarding is a serious form of psychopathology that has been associated with significant health and safety concerns, as well as the source of social and economic burden (Tolin, Frost, Steketee, & Fitch, 2008; Tolin, Frost, Steketee, Gray, & Fitch, 2008). Recent developments in the treatment of hoarding have met with some success for both individual and group treatments. Nevertheless, the cost and limited accessibility of these treatments leave many hoarding sufferers without options for help. One alternative is support groups that require relatively few resources. Frost, Pekareva-Kochergina, and Maxner (2011) reported significant declines in hoarding symptoms following a non-professionally run 13-week support group (The Buried in Treasures [BIT] Workshop). The BIT Workshop is a highly structured and short term support group. The present study extended these findings by reporting on the results of a waitlist control trial of the BIT Workshop. Significant declines in all hoarding symptom measures were observed compared to a waitlist control. The treatment response rate for the BIT Workshop was similar to that obtained by previous individual and group treatment studies, despite its shorter length and lack of a trained therapist. The BIT Workshop may be an effective adjunct to cognitive behavior therapy for hoarding disorder, or an alternative when cognitive behavior therapy is inaccessible. 相似文献

In two experiments, we examined the impact of the degree of match between sequential auditory perceptual organization processes
and the demands of a short-term memory task (memory for order vs. item information). When a spoken sequence of digits was
presented so as to promote its perceptual partitioning into two distinct streams by conveying it in alternating female (F)
and male (M) voices (FMFMFMFM)—thereby disturbing the perception of true temporal order—recall of item order was greatly impaired
(as compared to recall of item identity). Moreover, an order error type consistent with the formation of voice-based streams
was committed more quickly in the alternating-voice condition (Exp. 1). In contrast, when the perceptual organization of the
sequence mapped well onto an optimal two-group serial rehearsal strategy—by presenting the two voices in discrete clusters
(FFFFMMMM)—order, but not item, recall was enhanced (Exp. 2). The results are consistent with the view that the degree of
compatibility between perceptual and deliberate sequencing processes is a key determinant of serial short-term memory performance.
Alternative accounts of talker variability effects in short-term memory, based on the concept of a dedicated phonological
short-term store and a capacity-limited focus of attention, are also reviewed. 相似文献
