AGL StimSelect: Software for automated selection of stimuli for artificial grammar learning

Artificial grammar learning (AGL) is an experimental paradigm that has been used extensively incognitive research for many years to study implicit learning, associative learning, and generalization on the basis of either similarity or rules. Without computer assistance, it is virtually impossible to generate appropriate grammatical training stimuli along with grammatical or nongrammatical test stimuli that control relevant psychological variables. We present the first flexible, fully automated software for selecting AGL stimuli. The software allows users to specify a grammar of interest, and to manipulate characteristics of training and test sequences, and their relationship to each other. The user therefore has direct control over stimulus features that may influence learning and generalization in AGL tasks. The software, AGL StimSelect, enables researchers to develop AGL designs that would not be feasible without automatic stimulus selection. It is implemented in MATLAB.     

Long-Term Retention of Olfactory Discrimination Learning Set in Rats

We Value What Values Us: The Appeal of Identity-Affirming Science

Members of the public (Study 1; n =  184) and university students (Study 2; n =  101) evaluated a piece of research and indicated their support for its continuation. The research findings were held constant, but the methods that revealed those findings were attributed to either neuroscience or social science, and the conclusions based on those findings were biased either in favor of men or in favor of women. Study 1 revealed that participants were more positive about research that affirmed their gender identity and that was based on neuroscience rather than social science. Study 2 found this pattern to be apparent in more specialist samples. Indeed, participants with some scientific training were more influenced by research that affirmed the reader's gender identity. Participants with less scientific training, in comparison, were more influenced by the type of science described when making judgments about the value of the research. Contrary to popular claims, this suggests that scientific knowledge alone is no protection against the effects of bias on research evaluation. Implications for the practice and popularization of science are discussed.     

Ethical Aspects of Spirituality in Counseling

The authors review the professional literature related to spirituality and ethics in counseling. The American Counseling Association's (1995, 2005) code of ethics was used as a basis for exploring the possibilities and limits/boundaries appropriate for discussion of spirituality in counseling. Implications for practice and research are discussed.     

分析哲学和向黑格尔的回归

本文以黑格尔哲学的回归为主线,通过研究分析哲学对黑格尔哲学、对唯心主义所为何物认识的不足,以及实用主义者和分析哲学的代表人物对黑格尔哲学的吸收和借鉴,说明了分析哲学在其发展的过程中由排斥到借鉴黑格尔哲学,说明了黑格尔哲学依然是可以给予我们真知灼见的哲学,同时表达了作者对于一个真理王国的渴求。作者认为唯心主义概念是一个不清晰的、值得反思的概念。作者关于知识是历史的和社会的观点分析,也是很有见地的。

Blood lead (Pb) levels: a potential environmental mechanism explaining the relation between socioeconomic status and cardiovascular reactivity in children.

OBJECTIVE: A number of studies have shown an association between socioeconomic status (SES) and cardiovascular reactivity to acute stress. In addition, the authors recently reported that higher early childhood blood lead (Pb) levels are associated with significantly greater total peripheral (vascular) resistance (TPR) responses to acute stress. It is not known whether the SES-TPR association is mediated by underlying differences in blood lead levels. DESIGN: Participants were 9.5-year-old children (N=122) with established early childhood blood lead levels. MAIN OUTCOME MEASURES: Family SES was measured using the Hollingshead Index, blood lead levels were abstracted from pediatrician and state records, and children's cardiovascular responses to acute stressors were measured in the laboratory with impedance cardiography and an automated blood pressure monitor. RESULTS: Lower family SES was shown to be associated with significantly higher blood lead levels as well as significantly heightened systolic blood pressure, diastolic blood pressure, and TPR responses to acute stress tasks. A mediational analysis confirmed that Pb was a significant mediator of the SES-TPR reactivity association; some evidence also suggested moderation. CONCLUSION: These results suggest the importance of considering the chemical environment as well as social and psychological environment when evaluating cardiovascular effects of low SES.     

How does the purpose of inspection influence the potency of visual salience in scene perception?

Salience-map models have been taken to suggest that the locations of eye fixations are determined by the extent of the low-level discontinuities in an image. While such models have found some support, an increasing emphasis on the task viewers are performing implies that these models must combine with cognitive demands to describe how the eyes are guided efficiently. An experiment is reported in which eye movements to objects in photographs were examined while viewers performed a memory-encoding task or one of two search tasks. The objects depicted in the scenes had known salience ranks according to a popular model. Participants fixated higher-salience objects sooner and more often than lower-salience objects, but only when memorising scenes. This difference shows that salience-map models provide useful predictions even in complex scenes and late in viewing. However, salience had no effects when searching for a target defined by category or exemplar. The results suggest that salience maps are not used to guide the eyes in these tasks, that cognitive override by task demands can be total, and that modelling top-down search is important but may not be easily accomplished within a salience-map framework.
