The time required to conjoin stimulus features in high-rate serial presentation tasks was estimated in auditory and visual modalities. In the visual experiment, targets were defined by color, orientation, or the conjunction of color and orientation features. Responses were fastest in color conditions, intermediate in orientation conditions, and slowest in conjunction conditions. Estimates of feature conjunction time (FCT) were derived on the basis of a model in which features were processed in parallel and then conjoined, permitting FCTs to be estimated from the difference in reaction times between conjunction and the slowest single-feature condition. Visual FCTs averaged 17 msec, but were negative for certain stimuli and subjects. In the auditory experiment, targets were defined by frequency, location, or the conjunction of frequency and location features. Responses were fastest in frequency conditions, but were faster in conjunction than in location conditions, yielding negative FCTs. The results from both experiments suggest that the processing of stimulus features occurs interactively during early stages of feature conjunction. 相似文献

This study investigates the compensatory impact of cognitive aids on left and right temporal lobe epileptic patients suffering from verbal memory disorders, who were candidates for surgery. Cognitive aids are defined in the levels-of-processing framework and deal with the depth of encoding, the elaboration of information, and the use of retrieval cues. Results indicate differential compensatory impact for left and right epileptic patients and are discussed according to the HERA model and the compensation framework. 相似文献

Summary In two experiments the naming task was used to investigate the effect of spelling-to-sound regularity on performance for French words varying in frequency of usage. In both experiments the results showed a significant effect of regularity on naming latencies. Contrary to what has been found in previous experiments using English stimuli, the regularity effect did not vary as a function of word frequency. However, in both experiments significantly more errors, and specifically regularisation errors, were observed with low-frequency irregular words. Several possible interpretations of this atypical pattern of results are discussed. An additional observation was that the regularity effect, both on naming latencies and on error rates, and independently of frequency of use, was limited to the irregular words in which the idiosyncratic orthographic segment was either in initial or in medial position in the word. 相似文献

In the present study, the learning of a task in which the goal of the movement was not isomorphic with a specific movement pattern was examined. The subjects' (N = 48) goal in the task was to be both spatially and temporally accurate in reaching 4 targets with a right arm lever movement. After each acquisition trial, the displacement profile of the movement just produced was provided to all subjects as knowledge of performance (KP). The relative effectiveness of 2 possible references, with which subjects could compare the KP, was examined. One of the references examined was knowledge of results (KR), which was provided by reporting the total absolute timing and amplitude errors from the 4 targets. The other reference examined was a criterion template (CT), which was defined as the most efficient movement pattern for reaching the 4 targets. In the feedback display, CT was superimposed on the displacement profile of the movement just produced. A factorial design, in which 2 levels of KR (KR, no KR) were crossed with 2 levels of CT (CT, no CT), produced 4 feedback conditions. After 120 acquisition trials with feedback, immediate and delayed retention tests without feedback and a reacquisition test with KR (20 trials per test) were conducted. Acquisition results indicated that KR was a better reference than CT for per-forming the timing aspect of the movement and for producing the generalized motor program (GMP) associated with the most efficient movement pattern. Delayed retention results showed that KR was also a better reference than CT for learning the most efficient GMP. The calibration strategy undertaken by subjects who were provided with KR during acquisition explains the superiority of the KR reference. The calibration strategy is compared with the pattern-matching activity that was probably undertaken by subjects who had received CT as a reference. 相似文献

Age-related declines in attention and cognition have been associated with a difficulty in inhibiting the processing of task-irrelevant information (i.e., the inhibitory deficit hypothesis). However, evidence supporting the inhibitory deficit hypothesis remains equivocal, in part because of complexities in examining the processing of irrelevant stimuli using purely behavioral techniques. The effects of age on the processing of task-irrelevant stimuli were examined using scalp-recorded event-related brain potentials. Participants performed a visual discrimination task while standard and deviant auditory stimuli were presented in the background. Deviant auditory stimuli generated a mismatch negativity (MMN) wave that decreased with age, in part because of an age-related enhancement in sensory-evoked responses. The age-related changes in processing task-irrelevant auditory stimuli are consistent with the inhibitory deficit hypothesis and suggest that impaired inhibitory control of sensory input may play a role in the age-related declines in performance during selective attention tasks. 相似文献

One of the most crucial questions in the philosophy of law deals with the very nature of legal reasoning. Does this reasoning belong to logic or to rhetoric? This debate, increasingly centered on rhetoric, is not merely a question of language use; it covers and indicates a more basic choice between formal legalism — focusing on rational deduction from the law — and pragmatic judiciarism — focusing on reasonable debate in the court. Today, it is necessary to circumscribe the respective fields of logic and rhetoric in the language of law, while showing how they are sometimes complementary in the resolution of legal problems. But, even when we have acknowledged the need for a rhetoric accompanied by logic, we have to define that rhetoric cautiously. I confront a narrow rhetoric, often called argumentation, with a wider one of interrogative nature. There are two conceptions of rationality at stake. Their comparison enables us to raise the question of the foundation of law, as a locus to use arguments, as well as to solve social problems. 相似文献

The aim of the present study was to provide French normative data for 112 action line drawings. The set of action pictures
consisted of 71 drawings taken from Masterson and Druks (1998) and 41 additional drawings. It was standardized on six psycholinguistic
variables—that is, name agreement, image agreement, image variability, visual complexity, conceptual familiarity, and age
of acquisition (AoA). Naming latencies to the action pictures were collected, and a regression analysis was performed on the
naming latencies, with the standardized variables, as well as with word frequency and length, taken as predictors. A reliable
influence of AoA, name agreement, and image agreement on the naming latencies was observed. The findings are consistent with
previous published studies in other languages. The full set of these norms may be downloaded fromwww.psychonomic.org/archive/. 相似文献

The present study empirically examines the structure of police interview competencies in self‐reports of 230 police investigators suggesting five major underlying dimensions, that is, ‘Careful‐tenacious’, ‘Controlled‐non‐reactive’, ‘Dominant‐insisting’, ‘Communicative’ and ‘Benevolent’. These dimensions discriminate performance in a series of interview vignettes, grouped in terms of type of case (interviewing a suspect, a witness or a victim) and type of suspect. In addition self‐ratings on these dimensions are related to self‐estimated interview effectiveness in the same vignettes. Participants are further administered the NEO PI‐R (Costa, P. T., & McCrae, R. R. (1992). Professional manual: Revised NEO personality inventory (NEO‐PI‐R) and NEO five‐factor‐inventory (NEO‐FFI). Odessa, FL: Psychological Assessment Resources), enabling an examination of the relationship between the competence dimensions and their personality trait building blocks. The implications of this study for the development and coaching of police interview competencies are discussed. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

The sharing of processing resources between the senses was investigated by examining the effects of visual task load on auditory
event-related brain potentials (ERPs). In Experiment 1, participants completed both a zero-back and a one-back visual task
while a tone pattern or a harmonic series was presented. N1 and P2 waves were modulated by visual task difficulty, but neither
mismatch negativity (MMN) elicited by deviant stimuli from the tone pattern nor object-related negativity (ORN) elicited by
mistuning from the harmonic series was affected. In Experiment 2, participants responded to identity (what) or location (where) in vision, while ignoring sounds alternating in either pitch (what) or location (where). Auditory ERP modulations were consistent with task difficulty, rather than with task specificity. In Experiment 3, we investigated
auditory ERP generation under conditions of no visual task. The results are discussed with respect to a distinction between
process-general (N1 and P2) and processspecific (MMN and ORN) auditory ERPs. 相似文献
