The capacity of visual working memory was examined when complex objects from different categories were remembered. Previous studies have not examined how visual similarity affects object memory, though it has long been known that similar-sounding phonological information interferes with rehearsal in auditory working memory. Here, experiments required memory for two or four objects. Memory capacity was compared between remembering four objects from a single object category to remembering four objects from two different categories. Two-category sets led to increased memory capacity only when upright faces were included. Capacity for face-only sets never exceeded their nonface counterparts, and the advantage for two-category sets when faces were one of the categories disappeared when inverted faces were used. These results suggest that two-category sets which include faces are advantaged in working memory but that faces alone do not lead to a memory capacity advantage. 相似文献

This study assessed whether attendance rates in a workplace predicted subsequent outcome of employment-based reinforcement of cocaine abstinence. Unemployed adults in Baltimore methadone programs who used cocaine (N = 111) could work in a workplace for 4 hr every weekday and earn $10.00 per hour in vouchers for 26 weeks. During an induction period, participants provided urine samples but could work independent of their urinalysis results. After the induction period, participants had to provide urinalysis evidence of cocaine abstinence to work and maintain maximum pay. A multiple regression analysis showed that induction period attendance was independently associated with urinalysis evidence of cocaine abstinence under the employment-based abstinence reinforcement contingency. Induction period attendance may measure the reinforcing value of employment and could be used to guide the improvement of employment-based abstinence reinforcement. 相似文献

The axiom of recovery, while capturing a central intuition regarding belief change, has been the source of much controversy.
We argue briefly against putative counterexamples to the axiom—while agreeing that some of their insight deserves to be preserved—and
present additional recovery-like axioms in a framework that uses epistemic states, which encode preferences, as the object of revisions. This makes iterated revision possible and renders explicit the connection
between iterated belief change and the axiom of recovery. We provide a representation theorem that connects the semantic conditions
we impose on iterated revision and our additional syntactical properties. We show interesting similarities between our framework
and that of Darwiche–Pearl (Artificial Intelligence 89:1–29 1997). In particular, we show that intuitions underlying the controversial (C2) postulate are captured by the recovery axiom and
our recovery-like postulates (the latter can be seen as weakenings of (C2)). We present postulates for contraction, in the
same spirit as the Darwiche–Pearl postulates for revision, and provide a theorem that connects our syntactic postulates with
a set of semantic conditions. Lastly, we show a connection between the contraction postulates and a generalisation of the
recovery axiom.

Models of duration bisection have focused on the effects of stimulus spacing and stimulus modality. However, interactions between stimulus spacing and stimulus modality have not been examined systematically. Two duration bisection experiments that address this issue are reported. Experiment 1 showed that stimulus spacing influenced the classification of auditory, but not visual, stimuli. Experiment 2 used a wider stimulus range, and showed stimulus spacing effects for both visual and auditory stimuli, although the effects were larger for auditory stimuli. A version of Temporal Range Frequency Theory was applied to the data, and was used to demonstrate that the qualitative pattern of results can be captured with the single assumption that the durations of visual stimuli are less discriminable from one another than are the durations of auditory stimuli. 相似文献

Perceptual integration of audio-visual stimuli is fundamental to our everyday conscious experience. Eye-movement analysis may be a suitable tool for studying such integration, since eye movements respond to auditory as well as visual input. Previous studies have shown that additional auditory cues in visual-search tasks can guide eye movements more efficiently and reduce their latency. However, these auditory cues were task-relevant since they indicated the target position and onset time. Therefore, the observed effects may have been due to subjects using the cues as additional information to maximize their performance, without perceptually integrating them with the visual displays. Here, we combine a visual-tracking task with a continuous, task-irrelevant sound from a stationary source to demonstrate that audio-visual perceptual integration affects low-level oculomotor mechanisms. Auditory stimuli of constant, increasing, or decreasing pitch were presented. All sound categories induced more smooth-pursuit eye movement than silence, with the greatest effect occurring with stimuli of increasing pitch. A possible explanation is that integration of the visual scene with continuous sound creates the perception of continuous visual motion. Increasing pitch may amplify this effect through its common association with accelerating motion. 相似文献

This study examined 1,361 Chinese adolescents who reported self-injurious behaviors. Groups A and B both acknowledged deliberate self-injury, but only Group A had made a suicide attempt. Group C reported accidental self-injury. Deliberate self-injurers (Groups A and B) were more frequently girls, older, and with more suicidal ideation. Group A had more psychopathology, environmental and suicide-related risk factors than group B and C. Group C had higher depressive symptoms than noninjured controls. The study clarifies differences among self-injurious behavior groups based on expressed deliberate self-injury and self-reported suicide attempt. These three groups appear to present a continuum of risk. 相似文献

The Violence Risk Scale-Sexual Offender version (VRS-SO) is a rating scale designed to assess risk and predict sexual recidivism, to measure and link treatment changes to sexual recidivism, and to inform the delivery of sexual offender treatment. The VRS-SO comprises 7 static and 17 dynamic items empirically or conceptually linked to sexual recidivism. Dynamic items with higher ratings identify treatment targets linked to sexual offending. A modified stages of change model assesses the offender's treatment readiness and change. File-based VRS-SO ratings were completed on 321 sex offenders followed up an average of 10 years post-release. VRS-SO scores predicted sexual and nonsexual violent recidivism post-release and demonstrated acceptable interrater reliability and concurrent validity. A factor analysis of the dynamic items generated 3 factors labeled Sexual Deviance, Criminality, and Treatment Responsivity, all of which predicted sexual recidivism and were differentially associated with different sex offender types. The dynamic items together made incremental contributions to sexual recidivism prediction after static risk was controlled for. Positive changes in the dynamic items, measured at pre- and posttreatment, were significantly related to reductions in sexual recidivism after risk and follow-up time were controlled for, suggesting that dynamic items are indeed dynamic or changeable in nature. 相似文献

Using a computer‐based text analysis of 218 Asian Americans' writing samples, the authors found that enculturation as well as use of negative emotion and positive emotion words were associated with depressive symptoms. Enculturation was also found to moderate the relation between use of negative emotion words and cognitive‐affective depressive symptoms. Utilizando un análisis de texto computerizado de muestras escritas por 218 individuos Asiático‐americanos, los autores hallaron que la asimilación cultural y el uso de palabras de emoción positivas y negativas están asociadas con síntomas depresivos. También se halló que la asimilación cultural modera la relación entre el uso de palabras de emoción negativas y los síntomas depresivos cognitivo‐afectivos. 相似文献

This study proposes that a shared organizational vision develops cooperative interdependence among departments that, in turn, facilitates cross‐functional teams' organizational citizenship behavior (OCB). Team members indicated their organizations' shared vision, and leaders indicated the goal interdependence among departments and the OCB of the teams. Structural equation analysis suggested that a shared organizational vision shapes goal interdependence among departments that, in turn, affected the OCB of 101 cross‐functional teams. The analysis suggested combining independent and competitive goals, and this combined measure negatively predicted team OCB. These results suggest that a shared organizational vision and cooperative goals among departments are important foundations for cross‐functional teams to contribute to the effective working of organizations through citizenship behavior. 相似文献

One version of the argument for design relies on the assumption that the apparent fine-tuning of the universe for the existence
of life requires an explanation. I argue that the assumption is false. Philosophers who argue for the assumption usually appeal
to analogies, such as the one in which a person was to draw a particular straw among a very large number of straws in order
not to be killed. Philosophers on the other side appeal to analogies like the case of winning a lottery. I analyze the two
analogies and explain why the lottery analogy is the right one to use. In the light of such an analysis, we can see that although
the cosmic feature of being life-permitting is rare, it does not allow life-permitting possible universes to stand out because
there are other rare cosmic features that other possible universes have. 相似文献
