Studies of the therapeutic alliance typically use a one-with-many (OWM) design in which each therapist (the one) treats multiple clients (the many). This study used Kenny, Kashy, and Cook's (2006) OWM method to examine the composition of the therapeutic alliance and to analyze the association between alliance and outcome in a sample of 398 adolescents treated for substance abuse by 14 therapists. Both the client and therapist alliance ratings yielded large relationship variances, with limited consensus among clients treated by the same therapist about the quality of the alliance. If a client reported an especially strong alliance with his or her therapist, the therapist was likely to also report an especially strong alliance with that client (dyadic reciprocity). The association between the components of the alliance and treatment outcome was complicated, with different levels of measurement and different components of the alliance (perceiver, partner, or relationship) derived from different informants (therapist or client) relating to different outcomes. 相似文献

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

There is growing interest in whether and how sunk-cost effects for purely behavioral investments occur. In this article, we further discuss Cunha and Caldieraro's (2009) Behavioral Investment Sunk Cost (BISC) model and reconcile Otto's (2010) results with the BISC model predictions. We also report new data from two unpublished experiments that are consistent with the BISC model, and we discuss the conditions under which purely behavioral sunk-cost effects are likely to be observed. 相似文献

The purpose of this study is twofold. First, it aims to examine whether the impairment in peer functioning and social-cognitive
deficits (i.e., hostile attribution bias, social comprehension, social problem-solving) found in elementary school aged children
with ADHD also occur in adolescence. Second, it aims to provide evidence for a predictive relationship between these social-cognitive
deficits and an adolescent’s functional impairment in the social domain. To address these aims, several social-cognitive tasks
were administered to a small sample of young adolescents with ADHD (N = 27) and a comparison sample without an ADHD diagnosis (N = 18). Parent report of functional impairment and peer sociometric data were also gathered. Comparisons of both parent and peer
report of adolescent social functioning suggest that individuals with ADHD continue to experience difficulties with peers
into the adolescent years and data from the social-cognitive tasks show evidence of social comprehension and problem-solving
deficits. Further analyses indicated a significant link between functional impairment and social cognition. Findings herein
are discussed in the context of both the developmental changes that arise during adolescence and consideration of the importance
of social cognition for understanding the impaired social functioning experienced by adolescents with ADHD. 相似文献

Techniques commonly used to increase truth‐telling in most North American jurisdiction courts include requiring witnesses to discuss the morality of truth‐ and lie‐telling and to promise to tell the truth prior to testifying. While promising to tell the truth successfully decreases younger children's lie‐telling, the influence of discussing the morality of honesty and promising to tell the truth on adolescents' statements has remained unexamined. In Experiment 1, 108 youngsters, aged 8–16 years, were left alone in the room and asked not to peek at the answers to a test. The majority of participants peeked at the test answers and then lied about their transgression. More importantly, participants were eight times more likely to change their response from a lie to the truth after promising to tell the truth. Experiment 2 confirmed that the results of Experiment 1 were not solely due to repeated questioning or the moral discussion of truth‐ and lie‐telling. These results suggest that, while promising to tell the truth influences the truth‐telling behaviors of adolescents, a moral discussion of truth and lies does not. Legal implications are discussed.

Abstract: Contextualist accounts of free will recently proposed by Hawthorne and Rieber imply that the same action can be both free and unfree (depending on the attributor's context). This paradoxical consequence can be avoided by thinking of contexts not as constituted by arbitrary moves in a conversation, but rather by (relatively stable) social practices (such as the practices of attributing responsibility or of giving scientific explanations). The following two conditions are suggested as each necessary and jointly sufficient for free will: (i) the agent is able to form considered practical judgements and to act accordingly, and (ii) the agent (or some agent‐involving event) is the original cause of her actions. A contextualist reformulation of the second condition is developed according to which only contexts in which responsibility is attributed are relevant for the kind of original causation required for free will, which allows for a non‐relativist contextualism about free will. 相似文献

Children with autism spectrum disorder process many perceptual and social events differently from typically developing children,
suggesting that they may also form and recognize categories differently. We used a dot pattern categorization task and prototype
comparison modeling to compare categorical processing in children with high-functioning autism spectrum disorder and matched
typical controls. We were interested in whether there were differences in how children with autism use average similarity
information about a category to make decisions. During testing, the group with autism spectrum disorder endorsed prototypes
less and was seemingly less sensitive to differences between to-be-categorized items and the prototype. The findings suggest
that individuals with high-functioning autism spectrum disorder are less likely to use overall average similarity when forming
categories or making categorical decisions. Such differences in category formation and use may negatively impact processing
of socially relevant information, such as facial expressions. A supplemental appendix for this article may be downloaded from

Event detection is used to classify recorded gaze points into periods of fixation, saccade, smooth pursuit, blink, and noise.
Although there is an overall consensus that current algorithms for event detection have serious flaws and that a de facto
standard for event detection does not exist, surprisingly little work has been done to remedy this problem. We suggest a new
velocity-based algorithm that takes several of the previously known limitations into account. Most important, the new algorithm
identifies so-called glissades, a wobbling movement at the end of many saccades, as a separate class of eye movements. Part
of the solution involves designing an adaptive velocity threshold that makes the event detection less sensitive to variations
in noise level and the algorithm settings-free for the user. We demonstrate the performance of the new algorithm on eye movements
recorded during reading and scene perception and compare it with two of the most commonly used algorithms today. Results show
that, unlike the currently used algorithms, fixations, saccades, and glissades are robustly identified by the new algorithm.
Using this algorithm, we found that glissades occur in about half of the saccades, during both reading and scene perception,
and that they have an average duration close to 24 msec. Due to the high prevalence and long durations of glissades, we argue
that researchers must actively choose whether to assign the glissades to saccades or fixations; the choice affects dependent
variables such as fixation and saccade duration significantly. Current algorithms do not offer this choice, and their assignments
of each glissade are largely arbitrary. 相似文献

In this paper, I will discuss the responsibilities that scientists have for ensuring their work is interpreted correctly.
I will argue that there are three good reasons for scientists to work to ensure the appropriate communication of their findings.
First, I will argue that scientists have a general obligation to ensure scientific research is communicated properly based
on the vulnerability of others to the misrepresentation of their work. Second, I will argue that scientists have a special
obligation to do so because of the power we as a society invest in them as specialists and professionals. Finally, I will
argue that scientists ought to ensure their work is interpreted correctly based on prudential, self-interested considerations.
I will conclude by offering suggestions regarding policy considerations. 相似文献

Survey and behavioral measurements of interpersonal trust 总被引:1,自引:0,他引:1
Although many studies treat trust as a situational construct, individual differences can be used to study and predict trusting behavior. We report two studies, the first showing the psychometric properties of a new trust inventory (the Propensity to Trust Survey or PTS), the second study validating this inventory using the standard economic task, the Investment Game. The first study utilized online survey data (N > 8000) to show that the PTS scales were reliable and measured broad constructs related to Big Five personality domains. Trust was related to extraversion and negative neuroticism, and trustworthiness was related to agreeableness and conscientiousness. The second study (N = 90) validated the PTS trust scale as a predictor of behavior in the Investment Game. These findings are evidence that trust and trustworthiness are compound personality traits, and that PTS scales are preferable to general Big Five measures for predicting trusting behavior. 相似文献
