As illustrated by the mistaken, high-profile fingerprint identification of Brandon Mayfield in the Madrid Bomber case, and consistent with a recent critique by the National Academy of Sciences (2009), it is clear that the forensic sciences are subject to contextual bias and fraught with error. In this article, we describe classic psychological research on primacy, expectancy effects, and observer effects, all of which indicate that context can taint people's perceptions, judgments, and behaviors. Then we describe recent studies indicating that confessions and other types of information can set into motion forensic confirmation biases that corrupt lay witness perceptions and memories as well as the judgments of experts in various domains of forensic science. Finally, we propose best practices that would reduce bias in the forensic laboratory as well as its influence in the courts. 相似文献

Computerized adaptive testing under nonparametric IRT models 总被引:1,自引:0,他引:1
Nonparametric item response models have been developed as alternatives to the relatively inflexible parametric item response
models. An open question is whether it is possible and practical to administer computerized adaptive testing with nonparametric
models. This paper explores the possibility of computerized adaptive testing when using nonparametric item response models.
A central issue is that the derivatives of item characteristic Curves may not be estimated well, which eliminates the availability
of the standard maximum Fisher information criterion. As alternatives, procedures based on Shannon entropy and Kullback–Leibler
information are proposed. For a long test, these procedures, which do not require the derivatives of the item characteristic
eurves, become equivalent to the maximum Fisher information criterion. A simulation study is conducted to study the behavior
of these two procedures, compared with random item selection. The study shows that the procedures based on Shannon entropy
and Kullback–Leibler information perform similarly in terms of root mean square error, and perform much better than random
item selection. The study also shows that item exposure rates need to be addressed for these methods to be practical.
The authors would like to thank Hua Chang for his help in conducting this research. 相似文献

The neurophysiological correlates of face processing in adults and children with Asperger's syndrome
Past research has found evidence for face and emotional expression processing differences between individuals with Asperger's syndrome (AS) and neurotypical (NT) controls at both the neurological and behavioural levels. The aim of the present study was to examine the neurophysiological basis of emotional expression processing in children and adults with AS relative to age- and gender-matched NT controls. High-density event-related potentials were recorded during explicit processing of happy, sad, angry, scared, and neutral faces. Adults with AS were found to exhibit delayed P1 and N170 latencies and smaller N170 amplitudes in comparison to control subjects for all expressions. This may reflect impaired holistic and configural processing of faces in AS adults. However, these differences were not observed between AS and control children. This may result from incomplete development of the neuronal generators of these ERP components and/or early intervention. 相似文献

Theory and research suggest that Internet identification may account for some of the gender divide in Internet use. Internet identification is a type of domain identification, and is inherently bound with images of those who use the Internet, a domain traditionally conceived as masculine. Combining the "draw an Internet user" test with an Internet identification scale, this study tests two hypotheses: participants drawing gender-concordant images will (i) identify with and (ii) use the Internet more than those drawing gender-discordant images. Participants were 371 students (121 males, 250 females) from three universities in the United Kingdom and Australia. The need to challenge masculinized images of the Internet is discussed. 相似文献

Participants indicated whether a small dot was located near the top or bottom pole of a rotated object. Response times increased as a function of object orientation more for top trials than for bottom trials. The interaction between orientation and response was shown to be due to a relationship between response times and the dot's height on the screen. The orientation effect was influenced, positively and negatively, by a vertical arrangement of the response keys depending on whether the upper or lower key was used for the top response. Horizontal key placement produced an intermediate orientation effect, with asymmetries of about 180 degrees depending on which hand was used for top responses. This task appears to reflect spatial stimulus-response compatibilities more than object processing. 相似文献

In this article, we describe the translation and validation of the Dutch Big Five Inventory (BFI; John & Srivastava, 1999), a short instrument designed to measure the Big Five factors of personality. We obtained evidence of the instrument's good psychometric properties in terms of factorial equivalence to the English original and other BFI translations and the relative independence and internal consistency of the five scales. The findings suggest that the instrument can be used in diverse age groups without substantial changes in factor structure. The Dutch BFI scales showed similar demographic correlates as the English original, with higher Agreeableness and Conscientiousness and lower Neuroticism values in older participants, higher Neuroticism values in women, and higher Openness and Conscientiousness values in better educated participants. Use of the Dutch BFI will allow researchers to integrate their findings with the extant Big Five research literature. The brevity of the instrument will be appealing to researchers who are concerned about taxing the time and motivation of their participants. 相似文献

Terror management theory (TMT) posits that the need for self‐esteem develops out of the socialization process in which children learn to abide by parental and, eventually, societal standards of ‘goodness’ to feel securely embedded in a cultural belief system. According to TMT, feeling safely immersed in a meaningful conception of reality (i.e., the cultural worldview) ultimately functions to protect people from anxiety due to the uniquely human capacity to be cognizant of their eventual death. After presenting the basic tenets of this perspective, we review several lines of research supporting it and then address some common questions and criticisms of the theory such as how is a TMT view of anxiety consistent with evolutionary principles, why do people commit suicide, and how is self‐esteem pursued in non‐Western, self‐effacing cultures? Finally, we discuss some implications of TMT for understanding social problems and for pursuing meaning and self‐esteem in healthier, more socially productive ways. 相似文献

We review work in the major model systems for habituation in Drosophila melanogaster, encompassing several sensory modalities and behavioral contexts: visual (giant fiber escape response, landing response); chemical (proboscis extension reflex, olfactory jump response, locomotory startle response, odor-induced leg response, experience-dependent courtship modification); electric (shock avoidance); and mechanical (leg resistance reflex, cleaning reflex). Each model system shows several of Thompson and Spencer’s [Thompson, R. F., & Spencer, W. A. (1966). Habituation: A model phenomenon for the study of neuronal substrates of behavior. Psychological Review, 73, 16–43] parametric criteria for habituation: spontaneous recovery and dishabituation have been described in almost all of them and dependence of habituation upon stimulus frequency and stimulus intensity in the majority. Stimulus generalization (and conversely, the delineation of stimulus specificity) has given insights into the localization of habituation or the neural architecture underlying sensory processing.The strength of Drosophila for studying habituation is the range of genetic approaches available. Mutations have been used to modify specific neuroanatomical structures, ion channels, elements of synaptic transmission, and second-messenger pathways. rutabaga and dunce, genes of the cAMP signal pathway that have been studied most often in the reviewed experiments, have also been implicated in synaptic plasticity and associative conditioning in Drosophila and other species including mammals. The use of the Gal4/UAS system for targeting gene expression has enabled genetic perturbation of defined sets of neurons. One clear lesson is that a gene may affect habituation differently in different behaviors, depending on the expression, processing, and localization of the gene product in specific circuits. Mutations of specific genes not only provide links between physiology and behavior in the same circuit, but also reveal common mechanisms in different paradigms of behavioral plasticity. The rich repertoire of models for habituation in the fly is an asset for combining a genetic approach with behavioral, anatomical and physiological methods with the promise of a more complete understanding. 相似文献
