Integration of simultaneous auditory and visual information about an event can enhance our ability to detect that event. This is particularly evident in the perception of speech, where the articulatory gestures of the speaker's lips and face can significantly improve the listener's detection and identification of the message, especially when that message is presented in a noisy background. Speech is a particularly important example of multisensory integration because of its behavioural relevance to humans and also because brain regions have been identified that appear to be specifically tuned for auditory speech and lip gestures. Previous research has suggested that speech stimuli may have an advantage over other types of auditory stimuli in terms of audio-visual integration. Here, we used a modified adaptive psychophysical staircase approach to compare the influence of congruent visual stimuli (brief movie clips) on the detection of noise-masked auditory speech and non-speech stimuli. We found that congruent visual stimuli significantly improved detection of an auditory stimulus relative to incongruent visual stimuli. This effect, however, was equally apparent for speech and non-speech stimuli. The findings suggest that speech stimuli are not specifically advantaged by audio-visual integration for detection at threshold when compared with other naturalistic sounds. 相似文献

Undergraduate students in a Southeastern US University (n = 232) responded to an inventory that included retrospective measures of their parents’ style of parenting (authoritarian
vs. authoritative) and their own childhood psychological tendencies (insecurity vs. confidence), as well as their adult stressors
and political orientation. Authoritative parenting positively correlated with childhood confidence and negatively correlated
with both childhood insecurity and adult stressors. Conversely, authoritarian parenting was positively associated with childhood
insecurity and adult stressors but was not significantly correlated with childhood confidence. For the most part, parenting
styles, early childhood tendencies, and adult stressors were unrelated to adult political ideology, contrary to previous longitudinal
research reporting these connections. 相似文献

In the present study, we examined the effects of selective response inhibition on motor production using response force measures
within a task that was based on that of Aron and Verbruggen (Psychological Science, 19, 1146–1153, 2008). In each trial, participants were signaled to respond bimanually with the two index fingers or the two
middle fingers. After a short delay, a stop signal was sometimes presented, indicating that one of the two finger responses
should be withheld. A given response was slowed when the response on the other hand was stopped, replicating a previously
observed stopping interference effect. In addition, the given response was also made more forcefully when the response on
the other hand was stopped, indicating that the requirement to stop one activated response has global motor-level consequences
for other responses that are to be carried out normally. 相似文献

The use of rational agents for modelling real world problems has both been heavily investigated and become well accepted, with BDI (Beliefs, Desires, and Intentions) Logic being a widely used architecture to represent and reason about rational agency. However, in the real world, we often have to deal with different levels of confidence in the beliefs we hold, desires we have, and intentions that we commit to. This paper extends our previous framework that integrated qualitative levels of beliefs, desires, and intentions into BDI Logic. We describe an expanded set of axioms and properties of the extended logic. We present a modular structure for the semantics which involves a non-normal Kripke type semantics that may be used for other agent systems. Further, we demonstrate the usefulness of our framework with a scheduling task example. 相似文献

This paper evaluates 2 adjustments to common scoring approaches for situational judgment tests (SJTs). These adjustments can result in substantial improvements to item validity, reductions in mean racial differences, and resistance to coaching designed to improve scores. The first adjustment, applicable to SJTs that use Likert scales, controls for elevation and scatter (Cronbach & Gleser, 1953). This adjustment improves item validity. Also, because there is a White-Black mean difference in the preference for extreme responses on Likert scales (Bachman & O'Malley, 1984), these adjustments substantially reduce White-Black mean score differences. Furthermore, this adjustment often eliminates the score elevation associated with the coaching strategy of avoiding extreme responses (Cullen, Sackett, & Lievens, 2006). Item validity is shown to have a U-shaped relationship with item means. This holds both for SJTs with Likert score response formats and for SJTs where respondents identify the best and worst response option. Given the U-shaped relationship, the second adjustment is to drop items with midrange item means. This permits the SJT to be shortened, sometimes dramatically, without necessarily harming validity. 相似文献

The goals of the current study were to investigate the stability of temperamental exuberance across infancy and toddlerhood and to examine the associations between exuberance and social-emotional outcomes in early childhood. The sample consisted of 291 4-month-olds followed at 9, 24, and 36 months and again at 5 years of age. Behavioral measures of exuberance were collected at 9, 24, and 36 months. At 36 months, frontal electroencephalogram (EEG) asymmetry was assessed. At 5 years, maternal reports of temperament and behavior problems were collected, as were observational measures of social behavior during an interaction with an unfamiliar peer in the laboratory. Latent profile analysis revealed a high, stable exuberance profile that was associated with greater ratings of 5-year externalizing behavior and surgency, as well as observed disruptive behavior and social competence with unfamiliar peers. These associations were particularly true for children who displayed left frontal EEG asymmetry. Multiple factors supported an approach bias for exuberant temperament but did not differentiate between adaptive and maladaptive social-emotional outcomes at 5 years of age. 相似文献

The current study examined the effects of motivating operations on problem behavior and academic engagement for 2 students with autism. Classroom sessions were preceded by periods in which the participants had access or no access to the items functionally related to their problem behavior. Results suggested that presession access may result in lower levels of problem behavior and higher levels of academic engagement during classroom instruction. 相似文献

In the past, child bedtime routines have been examined through observation or sleep diaries. These methods are often expensive
and hinder study comparisons due to lack of consistent operational definitions of routines. This article describes the development
and psychometric evaluation of the Bedtime Routines Questionnaire (BRQ), a 31-item paper-and-pencil, parent-report measure
of children’s bedtime routines. The BRQ and related measures were completed by 226 caregivers of children ages 2 to 8. The
BRQ demonstrated a solid factor structure, adequate internal consistency, and fair validity coefficients. Overall, promising
results for the BRQ are reported. 相似文献

Media reports on the case of Rom Houben have constituted a new reminder of the risks of misdiagnosis with cases with apparent
vegetative state, particularly when following the clinical consensus of the care team as diagnostic criterion. Systematic
use of behavioral and non-behavioral assessment strategies (e.g., behavioral scales, event-related potentials, and neuro-imaging)
may help reduce the aforementioned risks. A new learning assessment strategy could also be considered part of the assessment
to extend the evaluation process. Signs of learning might be viewed as forms of concrete knowledge representing a basic level
of non-reflective consciousness. 相似文献
