Grouping and boundary perception are central to many aspects of sensory processing in cognition. We present a comparative study of recently published computational models of boundary perception in music. In doing so, we make three contributions. First, we hypothesise a relationship between expectation and grouping in auditory perception, and introduce a novel information-theoretic model of perceptual segmentation to test the hypothesis. Although we apply the model to musical melody, it is applicable in principle to sequential grouping in other areas of cognition. Second, we address a methodological consideration in the analysis of ambiguous stimuli that produce different percepts between individuals. We propose and demonstrate a solution to this problem, based on clustering of participants prior to analysis. Third, we conduct the first comparative analysis of probabilistic-learning and rule-based models of perceptual grouping in music. In spite of having only unsupervised exposure to music, the model performs comparably to rule-based models based on expert musical knowledge, supporting a role for probabilistic learning in perceptual segmentation of music. 相似文献

When the interval between a non-predictive cue and a target appearing at the same spatial location is longer than about 200 ms,
target performance is typically poorer than when the cue and target appear at different locations. Recent studies have shown
that this effect, known as inhibition of return (IOR), can occur at multiple cued locations, and is enhanced when multiple
cues are presented at the same spatial location. However, little is known about how the magnitude of IOR at one spatial location
is influenced by a subsequent or preceding cue presented at a different spatial location. We investigated this issue by presenting
single or multiple cues at varying inter-cue intervals prior to target onset. Results suggest that the magnitude of IOR at
a given location is influenced by the presentation of a preceding cue, but that once IOR occurs, it is unaffected by the presentation
of a subsequent cue. 相似文献

The present study aimed to develop an empirically-derived spatial activities questionnaire that would include gendered and neutral, as well as spatial and non-spatial activities. A total of 496 participants from Canada and the U.S. indicated how often they participated in 138 specific activities during their childhood. Exploratory factor analysis complemented by a multivariate analysis of variance resulted in eleven factors reflecting masculine-spatial; masculine-non- spatial; feminine-spatial; feminine-non-spatial and neutral-spatial components. Further item reduction resulted in a 27-item spatial activities questionnaire representing masculine spatial, masculine non-spatial, feminine spatial, and feminine non-spatial activities. This research constitutes the first step in the process of identifying a small set of activities that are clearly distinct in terms of their spatial nature and gender-typing. 相似文献

The present study examines the short-term cognitive effects of playing a sexually explicit video game with female “objectification” content on male players. Seventy-four male students from a university in California, U.S. participated in a laboratory experiment. They were randomly assigned to play either a sexually-explicit game or one of two control games. Participants’ cognitive accessibility to sexual and sexually objectifying thoughts was measured in a lexical decision task. A likelihood-to-sexually-harass scale was also administered. Results show that playing a video game with the theme of female “objectification” may prime thoughts related to sex, encourage men to view women as sex objects, and lead to self-reported tendencies to behave inappropriately towards women in social situations. 相似文献

The movement of defendants through the legal process who have been adjudicated incompetent to proceed is little studied, yet it is important. The purpose of this study was to provide empirical data regarding factors that affected the amount of time defendants adjudicated incompetent to proceed and ordered to undergo hospitalization remained in jail while awaiting transfer to a state hospital. Statewide data collected in Florida between July 2005 and June 2008 were used to determine the lengths of time incompetent defendants spent at certain stages in the legal process. The addition of forensic bed capacity following media attention and litigation resulted in a significant decrease in the amount of time defendants adjudicated incompetent to proceed waited in jail for transfer to a state hospital for treatment. The amount of time it took for completed commitment orders to be submitted to the state mental health authority by the Clerks of Court of each county accounted for a meaningful portion of days defendants spent in jail awaiting transfer to a state hospital, with considerable variation across counties with respect to waiting times. These findings reflect how various stakeholders can affect the amount of time defendants spend in jail while awaiting hospitalization. These issues are discussed in the context of controversy related to Florida's forensic mental health system, as well as issues related to the political process and funding of the state's mental health authority. 相似文献

I take the APA publication A Spiritual Strategy for Counseling and Psychotherapy (Richards and Bergin 2005), along with a devoted issue of Journal of Psychology and Theology (Nelson and Slife 2006), as a paradigmatic example of a trend. Other instances include the uncritical use of "Eastern" philosophy in Humanistic and Transpersonal Psychology, almost normative appeal to the "Sacred" within the psychology of spirituality, talk of "God in the brain" within neurological research, the neologism entheogen referring to psychedelic drugs, and calls for new specializations such as neurotheology and theobiology. In response to the legitimate ethical requirements of respect and openness regarding clients' religious worldviews, the trend is to make God an essential component in psychological theory. The argument is that God is active in the universe and especially in human affairs to such an extent that any accurate account of strictly psychological matters, not just a comprehensive, interdisciplinary purview that could include a distinct theological dimension, must include God as an explanatory factor. Less nuanced than standard theological thought about divine intervention—including a range of opinions from supernaturalism, to occasionalism, to providential and deistic naturalism—this trend would blur the epistemological differences between religion and science by appeal to claimed knowledge sources such as inspiration and revelation and thus undermine the achievements of evidence-based science and establish particularistic religious beliefs as standard explanatory accounts. The concern to include a spiritual, in contrast to a religious or theist, dimension in psychological theory is welcome; but elaborated approaches, such as my own and those of Roberto Assagioli, Viktor Frankl, and Ken Wilber, open to varied theological applications, already exist. 相似文献

Little attention typically is paid to the way self-report measures are translated for use in self-informant agreement studies. We studied two possible methods for creating informant measures: (a) the traditional method in which self-report items were translated from the first- to the third-person and (b) an alternative meta-perceptual method in which informants were directed to rate their perception of the targets' self-perception. We hypothesized that the latter method would yield stronger self-informant agreement for evaluative personality dimensions measured by indirect item markers. We studied these methods in a sample of 303 undergraduate friendship dyads. Results revealed mean-level differences between methods, similar self-informant agreement across methods, stronger agreement for Big Five dimensions than for evaluative dimensions, and incremental validity for meta-perceptual informant rating methods. Limited power reduced the interpretability of several sparse acquaintanceship effects. We conclude that traditional informant methods are appropriate for most personality traits, but meta-perceptual methods may be more appropriate when personality questionnaire items reflect indirect indicators of the trait being measured, which is particularly likely for evaluative traits. 相似文献

This meta‐analysis of 103 independent samples provides a comparative evaluation of the relationships associated with four emergent proactive constructs including proactive personality, personal initiative, voice, and taking charge. This study investigates comparative relationships among these focal proactive constructs and key organizational variables (i.e., job performance), personality traits (i.e., the Big Five), and individual variables (i.e., work experience). Results reveal significant correlations between proactivity and performance, satisfaction, affective organizational commitment, and social networking. Results also provide evidence that differentiates focal proactive constructs from the Big Five as well as individual differences in work experience, age, and general mental ability. Current progress towards a more integrative understanding of proactivity research is discussed. 相似文献
