Asymmetries in finger-tapping interference produced by mental versus manual rotation of Shepard and Metzler type objects

Two experiments were conducted using dual-task finger-tapping procedures to examine cerebral hemisphere laterization for mental versus manual rotation. Actual three-dimensional block-designs based on Shepard and Metzler's (1971) abstract three-dimensional cubes were constructed. Forty-eight right-handed introductory psychology students participated in each study. The first experiment showed greater right-hand than left-hand interference for mental rotation implicating more left-hemisphere involvement. In contrast, more left-hand than right-hand finger-tapping disruption with manual rotation was observed suggesting more right-hemisphere involvement. A second experiment was conducted to determine if the right-hemisphere involvement found with manual rotation was due to the manual activity of handling and rotating the blocks. Results showed that dual-task interference produced by irrelevant manual rotation combined with mental rotation was not lateralized. Thus, the pattern of results indicate that the manipulospatial processing required in the first experiment was responsible for the asymmetry implicating right-hemisphere involvement.     

Reading Xunzi through Nāmā: Two Ancient Inquiries into the Nature of Names

This essay is a comparison between two ancient theories of language—the 5th century BCE Indian etymologist Yāska and the 4th century BCE Chinese philosopher Xunzi 荀子. Specifically, it is a reading of the theory of “the rectification of names” in Xunzi through the lens of Yāska. Xunzi is known for his view that humanity’s innate tendencies need to be shaped through education and ritual. Similarly, ancient Indian authors like Yāska understand that a person is created, or made, through the performance of Vedic sacrifice. Both thinkers’ constructivist theories of language and meaning proceed from these ritual assumptions. However, Yāska would query Xunzi’s inherent distrust of multiple meanings of words and their negative effects on a functional state. Guided instead by a theory of the transcendence of Vedic language, Yāska would argue that the more one can proliferate possible meanings the more powerful a word becomes.     

Same clinic,different conceptions: Drug users’ and healthcare professionals’ perceptions of how stigma may affect clinical care

Stigma experienced by drug users by their healthcare professionals can be a barrier to treatment engagement, which in turn affects mortality and morbidity rates. Attribution theory suggests that stigma will be greatest whenever drug use is attributed to factors within personal control. Here, clients (n = 76) and healthcare professionals (n = 62) identified features that characterize good and bad clinical interactions, and responded to a vignette about a drug user who attributed his use to personal control or situational factors. Healthcare professionals completed the vignette and drug users gave their best guess of how healthcare professionals would react to this vignette. Clients and professionals held overlapping prototypes of clinical interactions. Clients overestimated both how negative healthcare professionals’ reactions would be, and the extent to which healthcare professionals’ reactions would accord with attribution theory. Despite healthcare professionals’ believing they are acting in nonstigmatizing ways, they may engender stigma in clinical situations more than they realize. Discrepancies between professionals’ hypothetical responses and clients’ anticipation of these responses are discussed in terms of the influence of self‐stigma and societal understandings of drug use and control. Attribution theory only offers a limited explanation for these discrepancies, because professionals’ beliefs about drug users are complex. Implications for theories of stigma and engagement with services are discussed, and the importance of clients’ anticipation of stigma is highlighted as a primary target for addressing treatment disengagement. Anti‐stigma campaigns may also benefit from changing their focus from individuals’ attributions to holistically addressing discrepant conceptions of treatment.     

Comparative Sacred Texts and Interactive Interpretation: Another Alternative to the “World Religions” Class

In this article we argue for an introductory course in the study of religion that proceeds through interactive interpretation as a responsible form of comparison. Interactive interpretation proceeds provisionally, and encourages students to formulate new questions of the materials instead of making final categories about the materials. We use examples from a typical classroom to show how we work with three pedagogical principles: (1) critical reading; (2) pluralism within religious traditions as well as between religious traditions; and (3) the use of the working hypothesis as a tool in analyzing religious texts. We also make an argument for textual reading as a form of living intellectual practice, which can work alongside of, and not in opposition to, other approaches to the study of religion, such as ethnographic or historical approaches.

The effect of subject-generated and experimentersupplied code words on the phonetic mnemonic system

The hypothesis tested proposed that subjects using the phonetic mnemonic system who were supplied code words by the experimenter would recall more numbers than either subjects generating their own code words or a control group. In Experiment 1,36 undergraduate subjects serving in a 3 × (3) mixed-factorial design confirmed the hypothesis, but the possibility existed that the superiority of the experimenter-supplied group was attributable to the failure of the subject-generated group to devise a complete set of code words. In Experiment 2 a new group of 12 self-generated subjects was tested with a modified procedure designed to maximize number of correct code words. However, the experimenter-supplied group recalled significantly more numbers than this group, too. In Experiment 3 the possibility was tested that the superiority of the experimenter-supplied subjects was an artifact based on insufficient training in the phonetic method of subjects creating code words. Accordingly, all 28 subjects received extended training before recall of a subject-generated group was tested against that of an experimenter-supplied group in a 2 × (2) factorial design. Once again the experimentersupplied group recalled significantly more numbers, confirming the hypothesis. These results represent an exception to the general finding that subject-generated mnemonics are superior to those supplied by the experimenter. The data suggest that the relative efficacy of the two sources interacts with the difficulty of the mnemonic.
