Four choice reaction time experiments documented a stimulus-response (S-R) compatibility effect involving the numbers of stimuli
and responses. In Experiment 1, the stimulus consisted of one or two tones, and the correct response was either one or two
taps of a response key. Responses were much faster with a compatible S-R assignment, in which the number of taps matched the
number of tones, than with an incompatible assignment in which these numbers mismatched. Experiments 2 and 3 replicated this
effect, using visual stimuli and bimodal stimuli, respectively, suggesting that auditory/manual rhythmic compatibility is
not essential to it. Experiment 4 showed that an analogous but smaller effect is obtained when stimuli are the digits 1 and
2. This new numerosity-based compatibility effect has general theoretical implications regarding the mechanisms responsible
for compatibility effects and practical implications for interface design. 相似文献

Recent studies have shown that the presentation of concurrent linguistic context can lead to highly efficient performance
in a standard conjunction search task by the induction of an incremental search strategy (Spivey, Tyler, Eberhard, & Tanenhaus,
2001). However, these findings were obtained under anomalously slow speech rate conditions. Accordingly, in the present study,
the effects of concurrent linguistic context on visual search performance were compared when speech was recorded at both a
normal rate and a slow rate. The findings provided clear evidence that the visual search benefit afforded by concurrent linguistic
context was contingent on speech rate, with normal speech producing a smaller benefit. Overall, these findings have important
implications for understanding how linguistic and visual processes interact in real time and suggest a disparity in the temporal
resolution of speech comprehension and visual search processes. 相似文献

Research that uses simple response time tasks and neuroimaging has emphasized that attentional preparation based on temporal
expectancy modulates processing at motor levels. A novel approach was taken to study whether the temporal orienting of attention
can also modulate perceptual processing. A temporal-cuing paradigm was used together with a rapid serial visual presentation
procedure, in order to maximize the processing demands of perceptual analysis. Signal detection theory was applied in order
to examine whether temporal orienting affects processes related to perceptual sensitivity or to response criterion (indexed
byďand beta measures, respectively). If temporal orienting implies perceptual preparation, we would expect to observe an increase
in perceptual sensitivity (ď) when a target appeared at expected, rather than unexpected, time intervals. Indeed, our behavioral results opened the possibility
that focusing attention on time intervals not only enhances motor processing, as has been shown by previous research, but
also might improve perceptual processing. 相似文献

Many studies of task switching have found that a prolonged preparation time reduces switch costs. An alternative manipulation
of task preparation is based on sequential task predictability, rather than preparation time. In Experiments 1 and 2 of the
present study, participants performed explicitly instructed task sequences (i.e., AABB) and were then transferred to a random
sequence. The observed benefit of predictability-based task preparation was not switch specific. In Experiment 3, the participants
changed from random to predictable tasks. The observed predictability benefit again was not switch specific. The data thus
suggest that task switching does not necessarily require a switch-specific reconfiguration process. Rather, task-specific
control processes may be needed in both task switches and repetitions. 相似文献

Memory for the final location of a moving target is often displaced in the direction of target motion, and this has been referred
to asrepresentational momentum. Characteristics of the target (e.g., velocity, size, direction, and identity), display (e.g., target format, retention interval,
and response method), context (landmarks, expectations, and attribution of motion source), and observer (e.g., allocation
of attention, eye movements, and psychopathology) that influence the direction and magnitude of displacement are reviewed.
Specific conclusions regarding numerous variables that influence displacement (e.g., presence of landmarks or surrounding
context), as well as broad-based conclusions regarding displacement in general (e.g., displacement does not reflect objective
physical principles, may reflect aspects of naive physics, does not solely reflect eye movements, may involve some modular
processing, and reflects high-level processes) are drawn. A possible computational theory of displacement is suggested in
which displacement (1) helps bridge the gap between perception and action and (2) plays a critical part in localizing stimuli
in the environment. 相似文献

This paper highlights the role of the Association of Medical School Psychologists (AMSP) as a bridge between academic medicine and psychology. AMSP’s affiliation with Division 12 of the American Psychological Association is discussed, but the primary focus is AMSP’s affiliation with the Association of American Medical Colleges (AAMC) and the AAMC’s Council of Academic Societies (CAS). The history, structure, activities, and goals of AAMC and CAS are examined. AMSP’s affiliation with AAMC is important for psychologists in medical schools and academic medical centers, and for psychology in general, because AAMC is the major voice of academic medicine in the US. AAMC activities affect medical education at all levels, as well as research and health services at academic medical centers, and health care policy at the national level. AMSP’s dual affiliation with AAMC’s CAS and APA’s Society of Clinical Psychology will increase psychology’s visibility and influence in academic medical centers and enhance the two-way flow of ideas and information between academic medicine and psychology. 相似文献

This study examined relations between stress and coping predictors and negative and positive outcomes in MS caregiving. A total of 222 carers and their care-recipients completed questionnaires at Time 1 and three months later, Time 2 (n = 155). Predictors included care-recipient characteristics (age, time since diagnosis, course and life satisfaction), and Times 1 and 2 carer problems, stress appraisal and coping. Dependent variables were Time 2 negative (anxiety, depression) and positive outcomes (life satisfaction, positive affect, benefits). Regressions indicated that, overall, the hypothesised direct effects of stress appraisal and coping strategies on positive and negative outcomes were supported. The hypothesised stress-buffering effects of positive reframing coping were also supported. All but one of the coping strategies were related to both positive and negative outcomes; specifically, practical assistance coping emerged as a unique predictor of distress. Of the model predictors, care-recipient life satisfaction emerged as the strongest and most consistent predictor of both positive and negative outcomes except benefit finding. Findings support the role of care-recipient characteristics and the carers appraisal and coping processes in shaping both positive and negative outcomes. The guiding framework and findings have the potential to inform interventions designed to promote well-being in carers. 相似文献

A new questionnaire, the Family Impact of Pain Scale (FIPS), was designed in order to assess the effects of chronic pain on
the significant other and family of the chronic pain patient. The FIPS is a 10-item self-report questionnaire examining the
effect of pain on domestic duties, social functioning and communication within the family. It was administered to 177 chronic
pain patients in two different samples to investigate its psychometric properties. Internal reliability (α = .94) and test–retest
reliability (r = 0.79) were high. Exploratory factor analysis suggested a two-factor solution, relating to physical limitations and difficulties
with communication. Construct validity was confirmed by significant Pearson correlations with pain intensity, pain distress,
mood and the use of pain coping skills (r = −0.22–0.74, all at p < .05). Outcome data also showed that the measure is sensitive to the effects of a cognitive behavioural pain management
intervention. 相似文献

We examined the potentially mediating effects of negative affectivity (NA) on the hope–depression relationship among a sample
of postpartum women. We also assessed the social support reported by these women and examined the possible mediating effects
of NA on the social support–postpartum depression relationship. Correlational analyses of data obtained from women (N = 98) who had given birth in the previous 6 months revealed that NA did not mediate either hope or social support in the
prediction of postpartum depression. Hope accounted for a significant degree of variance in postpartum depression. These data
suggest that hope has palliative effects among women following childbirth and these effects are not nullified or explained
by emotional predispositions. 相似文献
