This paper explores once-weekly psychotherapy with a 10-year-old boy who had been physically abused and spent six years in various foster-homes before being placed with his birth father and family. This case has many parallels with the experience of late adopted children who may struggle to think about and emotionally digest the experiences of their early lives, while also facing the challenge of joining a new family. This boy's longing for, resentment of and identification with his birth mother were actively communicated through drawings and re-enactments. His expectation of an object as unpredictable and unreliable made it difficult for him to apprehend different experiences with his family and in therapy. Exploring the nature of his internal objects and gradually enabling him to bring feeling and thought into closer proximity provided one way of giving meaning to experiences he could not remember or understand. Technical difficulties in working with a child who actively flaunted the boundaries of the sessions are considered, as is the importance of a containing network surrounding the child. 相似文献

Data collection can be the most time- and cost-intensive part of developmental research. This article describes some long-proposed but little-used research designs that have the potential to maximize data quality (reliability and validity) while minimizing research cost. In planned missing data designs, missing data are used strategically to improve the validity of data collection in one of two ways. Multiform designs allow one to increase the number of measures assessed on each participant without increasing each participant's burden. Two-method measurement designs allow one to reap the benefits of a cost-intensive gold-standard measure, using a larger sample size made possible by a rougher, cheaper measure. We explain each method using examples relevant to cognitive development research. With the use of analysis methods that produce unbiased results, planned missing data designs are an efficient way to manage cost, improve data quality, and reduce participant fatigue and practice effects. 相似文献

The temporal characteristics of speech can be captured by examining the distributions of the durations of measurable speech components, namely speech segment durations and pause durations. However, several barriers prevent the easy analysis of pause durations: The first problem is that natural speech is noisy, and although recording contrived speech minimizes this problem, it also discards diagnostic information about cognitive processes inherent in the longer pauses associated with natural speech. The second issue concerns setting the distribution threshold, and consists of the problem of appropriately classifying pause segments as either short pauses reflecting articulation or long pauses reflecting cognitive processing, while minimizing the overall classification error rate. This article describes a fully automated system for determining the locations of speech–pause transitions and estimating the temporal parameters of both speech and pause distributions in natural speech. We use the properties of Gaussian mixture models at several stages of the analysis, in order to identify theoretical components of the data distributions, to classify speech components, to compute durations, and to calculate the relevant statistics. 相似文献

Several studies have found that women tend to demonstrate stronger preferences for masculine men as short-term partners than as long-term partners, though there is considerable variation among women in the magnitude of this effect. One possible source of this variation is individual differences in the extent to which women perceive masculine men to possess antisocial traits that are less costly in short-term relationships than in long-term relationships. Consistent with this proposal, here we show that the extent to which women report stronger preferences for men with low (i.e., masculine) voice pitch as short-term partners than as long-term partners is associated with the extent to which they attribute physical dominance and low trustworthiness to these masculine voices. Thus, our findings suggest that variation in the extent to which women attribute negative personality characteristics to masculine men predicts individual differences in the magnitude of the effect of relationship context on women's masculinity preferences, highlighting the importance of perceived personality attributions for individual differences in women's judgments of men's vocal attractiveness and, potentially, their mate preferences. 相似文献

Research shows that target race can influence the decision to shoot armed and unarmed Black and White males (e.g., Correll, Park, Judd, & Wittenbrink, 2002). To date, however, research has only examined category level effects by comparing average responses to Blacks and Whites. The current studies investigated whether target prototypicality influences the decision to shoot above and beyond the effect of race. Here, we replicated racial bias in shoot decisions and demonstrated that bias was moderated by target prototypicality. As target prototypicality increased, participants showed greater racial bias. Further, when targets were unprototypic, racial bias reversed (e.g., participants mistakenly shot more unarmed Whites than Blacks). Study 2 examined whether these effects were observed among police officers. Although police showed no racial bias on average, target prototypicality significantly influenced judgments. Across both studies, sensitivity to variability in Whites' prototypicality drove these effects, while variation in Black prototypicality did not affect participants' decisions. 相似文献

The reorientation task is a paradigm that has been used extensively to study the types of information used by humans and animals to navigate in their environment. In this task, subjects are reinforced for going to a particular location in an arena that is typically rectangular in shape. The subject then has to find that location again after being disoriented, and possibly after changes have been made to the arena. This task is used to determine the geometric and featural cues that can be used to reorient the agent in the arena. The purpose of the present paper is to present several simulation results that show that a simple neural network, a perceptron, can be used to generate many of the traditional findings that have been obtained using the reorientation task. These results suggest that reorientation task regularities can be explained without appealing to a geometric module that is a component of spatial processing. 相似文献

We investigated the effects of adaptation to mouth shapes associated with different spoken sounds (sustained /m/ or /u/) on
visual perception of lip speech. Participants were significantly more likely to label ambiguous faces on an /m/-to-/u/ continuum as saying /u/ following adaptation to /m/ mouth shapes than they
were in a preadaptation test. By contrast, participants were significantly less likely to label the ambiguous faces as saying /u/ following adaptation to /u/ mouth shapes than they were in a preadaptation
test. The magnitude of these aftereffects was equivalent when the same individual was shown in the adaptation and test phases
of the experiment and when different individuals were presented in the adaptation and test phases. These findings present
novel evidence that adaptation to natural variations in facial appearance influences face perception, and they extend previous
research on face aftereffects to visual perception of lip speech. 相似文献

Many species have been shown to encode multiple sources of information to orient. To examine what kinds of information animals
use to locate a goal we manipulated cue rotation, cue availability, and inertial orientation when the food-storing Clark’s
nutcracker (Nucifraga columbiana) was searching for a hidden goal in a circular arena. Three groups of birds were used, each with a different goal–landmark
distance. As the distance between the goal and the landmark increased, nutcrackers were less accurate in finding the correct
direction to the goal than they were at estimating the distance (Experiment 1). To further examine what cues the birds were
using to calculate direction, the featural cues within the environment were rotated by 90° and the birds were either oriented
when searching (Experiments 2 and 3) or disoriented (Experiment 3). In Experiment 4, all distinctive visual cues were removed
(both internal and external to the environment), a novel point of entry was used and the birds were either oriented or disoriented.
We found that disorienting the nutcrackers so that they could not use inertial cues did not influence the birds’ total search
error. The birds relied heavily but not completely on cues within the environment, as rotating available cues caused them
to systematically shift their search behavior. In addition, the birds also relied to some extent on Earth-based cues. These
results show the flexible nature of cue use by the Clark’s nutcracker. Our study shows how multiple sources of spatial information
may be important for extracting multiple bearings for navigation. 相似文献
