Illusory conjunctions in the time domain are binding errors for features from stimuli presented sequentially but in the same spatial position. A similar experimental paradigm is employed for the attentional blink (AB), an impairment of performance for the second of two targets when it is presented 200–500 msec after the first target. The analysis of errors along the time course of the AB allows the testing of models of illusory conjunctions. In an experiment, observers identified one (control condition) or two (experimental condition) letters in a specified color, so that illusory conjunctions in each response could be linked to specific positions in the series. Two items in the target colors (red and white, embedded in distractors of different colors) were employed in four conditions defined according to whether both targets were in the same or different colors. Besides the U-shaped function for hits, the errors were analyzed by calculating several response parameters reflecting characteristics such as the average position of the responses or the attentional suppression during the blink. The several error parameters cluster in two time courses, as would be expected from prevailing models of the AB. Furthermore, the results match the predictions from Botella, Barriopedro, and Suero’s (Journal of Experimental Psychology: Human Perception and Performance, 27, 1452–1467, 2001) model for illusory conjunctions. 相似文献

Factor structure and measurement invariance of the Wisconsin Schizotypy scales across gender and age
Fonseca-Pedrero E Paino M Lemos-Giráldez S Sierra-Baigrie S Muñiz J 《The Spanish journal of psychology》2010,13(2):941-950
The Wisconsin Schizotypy Scales are among the most widely used instruments for the assessment of psychosis proneness. The main goal of the present work was to study the dimensional structure underlying the Revised Physical Anhedonia Scale (RPhA), the Revised Social Anhedonia Scale (RSAS), the Magical Ideation Scale (MIS) and the Perceptual Aberration Scale (PAS). It was also explored whether the dimensions underlying these scales were invariant across gender and age. The sample was made up of 710 university students with a mean age of 19.8 years (SD = 1.9). The results showed that the dimensional structure of the Wisconsin scales was similar to that found in previous studies, displaying a Positive dimension and a Negative dimension, the Social Anhedonia Scale being related to both dimensions. Moreover, the factor structure of the schizotypy scales was found to be invariant across participants' gender and age. 相似文献

The availability of adequate instruments for the assessment of nicotine dependence is an important factor that is relevant in the area of tobacco addiction. In this study, we present a Spanish validation of the Nicotine Dependence Syndrome Scale (NDSS) (Shiffman, Waters, & Hickcox, 2004). The sample was composed ofpatients, all daily smokers, who visited their General Practitioner (GP) at five Primary Health Care Centers in different cities of Spain (N = 637). The results indicated adequate reliability for the general factor that assesses nicotine dependence (NDSS-Total) (Cronbach's alpha = .76). Factor analysis confirms the five factors of the original validation: Drive, Continuity, Stereotypy, Priority, and Tolerance. It must be noted that reliability is adequate for the first, and moderate or low for the rest. The NDSS-T and its scales correlate significantly with the Fagerstr?m Test for Nicotine Dependence (FTND), with the nicotine dependence criteria of the Diagnostic and Statistical Manual of Mental Disorders IV (DSM-IV) as assessed through the Structured Clinical Interview for DSM-IV (SCID), with carbon monoxide levels in expired air (CO), and with the number of cigarettes smoked. The ROC curve indicates that the NDSS-T has a score of .79 which is under the curve (.69 for the FTND), thus the prediction of nicotine dependence is adequate. We conclude that this instrument is useful (in terms of its total score NDSS-T) for assessing nicotine dependence for Spanish smokers (in Spain), as has been found in other countries, language groups, and cultures. 相似文献

This article presents a set of research studies that aim to adapt Carol Ryff's scales of psychological wellbeing (SPWB) and to analyze its psychometric properties in adolescents. The first two studies focused on the reliability and factorial validity of different Portuguese short versions of SPWB, revealing measurement models inadequacies and low internal consistency. In the third study we developed a shortened version (30 items), taking into account the application of psychometric criteria suggested by van Dierendonck (2005). The scales of this version revealed better reliability and adequate goodness of fit indices for the six-factor model, as proposed by Carol Ryff's PWB theory. Although further research focused on the psychometrical properties reanalysis of this shortened version of SPWB is needed, this article provides a contribution to the research and intervention on positive mental health during adolescence. 相似文献

The present research demonstrates a dissociation between explicit and implicit intergroup evaluation in the reciprocal attitudes between indigenous (Mapuche) and non‐indigenous Chileans. In both social groups, the explicit measures of attitudes towards the respective in‐group and out‐group were compared with the Implicit Association Test scores. The results indicate that the members of the low‐status minority might explicitly express a moderate evaluative preference for their in‐group but might implicitly devalue it. Conversely, the members of the high‐status majority might implicitly devalue their out‐group but might explicitly express no bias. These results are theoretically framed in terms of system justification, conventional stereotypes and motivated correction processes. 相似文献

A haptic pedal has been designed to emulate the behaviour of a common vehicle pedal and render superimposed vibrations with different characteristics. It was installed in a driving simulator, as an accelerator pedal with the secondary function of a vibrotactile Frontal Collision Warning (FCW). The efficacy and feeling of this solution was tested with 30 subjects using vibrotactile signals with 0.50, 1.05, and 1.60 Nm, at 2.5, 5, and 10 Hz, against a baseline visual FCW. Participants had to match the speed of a leading vehicle when the FCW was triggered. Their braking response was evaluated in terms of brake reaction time, matching speed time, control of velocity and headway reduction. Driver’s feelings were assessed with Kansei methodologies. Haptic stimuli were found to be more effective than visual signals, and the characteristics of the vibration also influenced the results. The best performance was achieved at the maximum amplitude, and in the range between 5 and 10 Hz. The perceived functionality and discomfort followed a trend coherent with the objective measurements. The conclusions of this study may be applied to develop effective and safe warning systems in vehicles, limiting the annoyance that they might cause to drivers. 相似文献

Voice quality is an important perceptual cue in many disciplines, but knowledge of its nature is limited by a poor understanding
of the relevant psychoacoustics. This article (aimed at researchers studying voice, speech, and vocal behavior) describes
the UCLA voice synthesizer, software for voice analysis and synthesis designed to test hypotheses about the relationship between
acoustic parameters and voice quality perception. The synthesizer provides experimenters with a useful tool for creating and
modeling voice signals. In particular, it offers an integrated approach to voice analysis and synthesis and allows easy, precise,
spectral-domain manipulations of the harmonic voice source. The synthesizer operates in near real time, using a parsimonious
set of acoustic parameters for the voice source and vocal tract that a user can modify to accurately copy the quality of most
normal and pathological voices. The software, user’s manual, and audio files may be downloaded from http:// brm.psychonomic-journals.org/content/supplemental.

The present article introduces SYLLABARIUM, a new Web tool addressing the needs of linguists, psycholinguists, and cognitive
scientists who work with Spanish and/or Basque and are interested in retrieving information about several syllable-related
parameters. This new online syllabic database allows the user to generate complete lists of Spanish and Basque syllables with
information about the syllable frequency. Among other measures, for a given orthographic syllable, SYLLABARIUM provides its
number of occurrences (i.e., the type frequency), the summed lexical frequency of the words that contain this syllable (i.e.,
the token frequency), and the positional distribution of type and token frequencies. The cross-language feature of SYLLABARIUM
is of special interest to researchers aiming to explore the influence of the syllable in bilingualism. The Web tool is available
at www.bcbl.eu/syllabarium. 相似文献

Augmented reality (AR) is a new technology in which various virtual elements are incorporated into the user's perception of the real world. The most significant aspect of AR is that the virtual elements add relevant and helpful information to the real scene. AR shares some important characteristics with virtual reality as applied in clinical psychology. However, AR offers additional features that might be crucial for treating certain problems. An AR system designed to treat insect phobia has been used for treating phobia of small animals, and positive preliminary data about the global efficacy of the system have been obtained. However, it is necessary to determine the capacity of similar AR systems and their elements that are designed to evoke anxiety in participants; this is achieved by testing the correspondence between the inclusion of feared stimuli and the induction of anxiety. The objective of the present work is to validate whether the stimuli included in the AR-Insect Phobia system are capable of inducing anxiety in six participants diagnosed with cockroach phobia. Results support the adequacy of each element of the system in inducing anxiety in all participants. 相似文献

The present study examined whether results of athletes' eye movements while they observe fencing attacks reflect their actual information pickup by comparing these results with others gained with temporal and spatial occlusion and cuing techniques. Fifteen top-ranking expert fencers, 15 advanced fencers, and 32 sport students predicted the target region of 405 fencing attacks on a computer monitor. Results of eye movement recordings showed a stronger foveal fixation on the opponent's trunk and weapon in the two fencer groups. Top-ranking expert fencers fixated particularly on the upper trunk. This matched their performance decrements in the spatial occlusion condition. However, when the upper trunk was occluded, participants also shifted eye movements to neighboring body regions. Adding cues to the video material had no positive effects on prediction performance. We conclude that gaze behavior does not necessarily represent information pickup, but that studies applying the spatial occlusion paradigm should also register eye movements to avoid underestimating the information contributed by occluded regions. 相似文献
