What makes two images look similar? Here we test the hypothesis that perceived similarity of artwork is related to basic image statistics to which the early visual system is attuned. In two experiments, we employ multidimensional scaling (MDS) analysis of paired-image similarity ratings from observers for paintings. Two sets of images, classified as “landscapes” and “portraits/still-life”, are tested separately. For the landscapes, we find that one of the first two MDS scales of similarity is strongly correlated with a basic greyscale image statistic, whereas the other dimension can be accounted for by a semantic variable (representation of people). For portrait/still-life, the first two MDS scales of similarity are most highly correlated with semantic variables. Linear combinations of statistical and nonstatistical features achieve improved predictive values for the first two MDS scales for both sets. The statistics that play the largest role in shaping similarity judgements in our tests are the activity fraction measure of sparseness and the log-log slope of the spatial frequency amplitude spectrum. We discuss these results in the context of scene perception and in terms of efficient coding of statistical regularities in scenes.  相似文献

Eye movement desensitization and reprocessing (EMDR) is a relatively new form of psychotherapy for post‐traumatic symptoms of relevance to systemic therapists. The literature available on individual EMDR in traumatized children is reviewed in this article. A sample of eight studies was examined, consisting of three controlled trials, two uncontrolled studies and three case reports or series. The controlled trials compared EMDR with waiting list controls or cognitive behavioural therapy (CBT). The study samples were small and their methodological quality variable. In all the studies, the results suggested a positive effect for EMDR but did not appear superior to CBT. It is therefore possible that systemic interventions may be improved by the integration of EMDR and family therapy with children and adolescents.  相似文献

To determine the early school age effects of an intervention program for low SES, black teenage mothers and their term and preterm infants, a subsample of 61 mother-child dyads was assessed when the children were 5 to 8 years of age. The mothers and children were videotaped in a storytelling interaction together and then interviewed and tested. The child interviews included the Pictorial Scale of Perceived Competence, the Peabody Picture Vocabulary Test, the Wide Range Achievement Test, and the Bender Visual Motor Gestalt Test. The maternal interviews included a demographic questionnaire, the Rosenberg Self Esteem Scale, the Eyberg Child Behavior Inventory, the Parenting Stress Index, and the Vocabulary subtest of the Wechsler Adult Intelligence Scale. Analyses of variance yielded no intervention effects and no effects of prematurity on any of the child or mother measures. Correlation analysis, however, yielded a number of significant relations between socioeconomic status and child and maternal outcome measures. These findings suggest that the effects of intervention may be short-term for this population, and that low socioeconomic status (SES) may override the effects of early intervention and prematurity by the time children reach school age.  相似文献

Differences between different style‐depressed mothers, intrusive and withdrawn, were examined by the use of the Behavioral Inhibition and Activation Scales (BIS/BAS) and EEG activity from the mid‐frontal and parietal regions. Analyses revealed that withdrawn mothers had left frontal EEG hypoactivation, higher Behavior Inhibition (BIS), and lower Behavior Activation (BAS) scores than the intrusive mothers. Further analysis revealed that the BIS, the BAS reward and the BAS‐BIS difference scores were related to frontal EEG asymmetry and power scores. BIS scores were also related to the mothers' withdrawn interaction style, supporting the use of the BIS/BAS as a screening instrument to help identify intrusive and withdrawn depressed mothers. ©2001 Michigan Association for Infant Mental Health.  相似文献

Pigeons' choosing between fixed-interval and random-interval schedules of reinforcement was investigated in three experiments using a discrete-trial procedure. In all three experiments, the random-interval schedule was generated by sampling a probability distribution at an interval (and in multiples of the interval) equal to that of the fixed-interval schedule. Thus the programmed delays to reinforcement on the random alternative were never shorter and were often longer than the fixed interval. Despite this feature, the fixed schedule was not strongly preferred. Increases in the probability used to generate the random interval resulted in decreased preferences for the fixed schedule. In addition, the number of consecutive choices on the preferred alternative varied directly with preference, whereas the consecutive number of choices on the nonpreferred alternative was fairly constant. The probability of choosing the random alternative was unaffected by the immediately prior interval encountered on that schedule, even when it was very long relative to the average value. The results loosely support conceptions of a \"preference for variability\" from foraging theory and the \"utility of behavioral variability\" from human decision-making literatures.  相似文献

In her commentary of Field (1999), Hammerl (1999) has drawn attention to several interesting points concerning the issue of contingency awareness in evaluative conditioning. First, she comments on several contentious issues arising from Field's review of the evaluative conditioning literature, second she critiques the data from his pilot study and finally she argues the case that EC is a distinct form of conditioning that can occur in the absence of contingency awareness. With reference to these criticisms, this reply attempts to address Hammerl's comments by exploring the issues of how awareness is defined, how it is best measured, and whether it is reasonable to believe that EC uniformly occurs in the absence of contingency awareness. The article concludes that the available evidence supports Field's proposition that EC is, in fact, Pavlovian learning. Copyright 2000 Academic Press.  相似文献

Opinion poll data from 123 national sample surveys of the adult general population and 35 national and local sample surveys of adult religious populations are used to study changes in the status and influence of the Bible in Britain since the Second World War. The principal measures of ‘Bible-centricism’ comprise Bible ownership, readership, knowledge, literalism, beliefs, and attitudes. The analysis proceeds both at top-line level and by breaks for gender, age, social class, religious denomination, and churchgoing. Twelve broad conclusions are drawn, with declining allegiance to the Bible visible on various fronts, even among regular churchgoers. In an everyday sense, one interpretation could be that Christianity is becoming de-coupled from the holy book on which it is founded. This process, mirroring declines in other religious indicators, is attributed to the waning influence of three principal agencies of religious socialisation (church/Sunday school, state school, parents) which formerly underpinned the Bible’s role in faith and society.  相似文献

This review briefly summarizes recent empirical research on touch. The research includes the role of touch in early development, touch deprivation, touch aversion, emotions that can be conveyed by touch, the importance of touch for interpersonal relationships and how friendly touch affects compliance in different situations. MRI data are reviewed showing activation of the orbitofrontal cortex and the caudate cortex during affective touch. Physiological and biochemical effects of touch are also reviewed including decreased heart rate, blood pressure and cortisol and increased oxytocin. Similar changes noted following moderate pressure massage appear to be mediated by the stimulation of pressure receptors and increased vagal activity. Increased serotonin and decreased substance P may explain its pain-alleviating effects. Positive shifts in frontal EEG also accompany moderate pressure massage along with increased attentiveness, decreased depression and enhanced immune function including increased natural killer cells, making massage therapy one of the most effective forms of touch.  相似文献

Changes in imitative behavior and attentiveness were observed in 40 infants when they were 2 to 6 months of age. The facial expressions happy, sad, and surprised were modeled in a trials-to-criterion procedure, and the infants' looking time and mouth movements were recorded by an observer who was unaware of the face being modeled. In addition, the observer recorded her guess as to the expression being modeled by the corresponding expression on the infant's face and rated the infant's expressivity. The results suggested that looking time, correspondence between the mouth expression of the infant and the mouth expression modeled, accuracy of the observer's guess, and expressivity ratings decreased from 2 to 3 and 4 to 6 months. Although matching of mouth movements with the modeled mouth movements and accuracy of guesses were greater than chance over the 2 to 6 month-period, the decreases in these measures suggest that imitative behavior declined across early infancy. The decrease in looking time suggests that imitative behavior and attentiveness may be related and highlights the limitation of this paradigm for assessing the development of imitation during early infancy.  相似文献
