Semantic mechanisms in paralexia

This study explores the effects of semantic constraints on the occurrence of paralexic responses in two patients who tend to produce semantic errors in reading aloud. In the first experiment, semantic constraints were provided by using words as proper names (e.g., “brown” vs. “Sam Brown”), and in the second by using short, highly familiar phrases to restrict the meaning of the target word (e.g., the polar bear; green with envy). These constraints were found to be effective in reducing the frequency of paralexic errors.     

A developmental study of visual search behavior

Children in second, fourth and sixth grades and college sophomores were compared on a visual search and scanning task under three experimental condilions. In Condition I, a single target letter was sought in a list of letters of low visual confusability. In Condition II, two target letters were sought but only one appeared in a given list. In Condition III, a single target letter was sought in a list of letters of high confusability. Search time decreased with age in all three tasks. Searching for two targets was no harder than searching for one. A highly confusable visual context increased search time at all age levels.     

The word order problem in agrammatism : II. Production

This study demonstrates that agrammatic aphasics have difficulty describing relations that are signified by the order of noun phrases around verbs or prepositions. The word order deficit is found in a Sentence Order Task, in which written words must be arranged linearly to form a sentence, as well as in oral production. Ordering tendencies reflect factors like animacy or potency, rather than the systematic use of syntactic rules. These results point to a fundamental syntactic disorder in agrammatism.     

Cross-Cultural Testing of Three Social Cognitive Theories: An Application to Condom Use1

The aim of this study was to test the cross-cultural validity of Fishbein and Ajzen's theory of reasoned action, Ajzen's theory of planned behavior, and Triandis' theory of interpersonal behavior and to apply them to understanding the intention to use a condom with a new partner in three ethnocultural communities: Latin American, English-speaking Caribbean, and South Asian. All respondents were recruited from multiple ethnocultural-venues using predetermined sampling frames and quotas for each community. The results indicated that the three theories have cross-cultural validity, but the theories of Ajzen and Triandis performed better than the theory of Fishbein and Ajzen. It is recommended that role beliefs and moral norm (personal normative belief) be added to Ajzen's model to maximize its predictive and explanatory ability.     

Receiving the promised blessing: Missionary reflections on ‘Ishmae's (mostly female) descendants‘

The Arabian Mission of the Dutch Reformed Church set out in 1889 to introduce Christianity to the Muslims of the Gulf and Arabian Peninsula. The Mission failed in its efforts at proselytism, but persevered for 70 years providing medical and educational services. In the process, the Arabian missionaries produced an historical record of culture and society — especially about women — that is unparalleled in any other available sources. These sources are both technical and dispassionate as well as up‐close and highly personal, and are written with a point of view that tells us as much about the missionaries and their changing times as about men, women and society in the villages and towns of the Gulf, Hasa and Najd.     

British,Asian and Hindu: identity,self‐narration and the ethnographic interview

This article, based on a longitudinal study of young British Hindus’ perceptions of their religious tradition, explores their understandings of themselves as ‘British’, ‘Asian’ and Hindu’ [1] [1] The Longitudinal Study of Young British Hindus’ Perceptions of their Religious Tradition was funded by the Leverhulme Trust and directed by Professor Robert Jackson in the Warwick Religions and Education Research Unit, University of Warwick 1995‐97. Earlier ethnographic study of these young people is reported in Jackson and Nesbitt (1993). View all notes. A theoretical framework is provided by psychologists’ and philosophers’ acknowledgement of the processual, interactive, integrative nature of identity and the conceptualisation of it as both narrative and interpretative. The young people's narratives of identity are contextualised by the ‘between two cultures’ debate, and by Jacobson's (1997) recent analysis of the factors in young British Pakistanis’ increasing preference for an Islamic rather than Asian or Pakistani identity. It is suggested that a binary model is over simple and that ‘Hindu’ emerges as a transgenerational, core identity, but with significant differences from the young South Asian Muslims’ preferred Islamic identity.

     

Mirror neurons and the simulation theory of mind-reading

A new class of visuomotor neuron has been recently discovered in the monkey's premotor cortex: mirror neurons. These neurons respond both when a particular action is performed by the recorded monkey and when the same action, performed by another individual, is observed. Mirror neurons appear to form a cortical system matching observation and execution of goal-related motor actions. Experimental evidence suggests that a similar matching system also exists in humans. What might be the functional role of this matching system? One possible function is to enable an organism to detect certain mental states of observed conspecifics. This function might be part of, or a precursor to, a more general mind-reading ability. Two different accounts of mind-reading have been suggested. According to ‘theory theory', mental states are represented as inferred posits of a naive theory. According to ‘simulation theory', other people's mental states are represented by adopting their perspective: by tracking or matching their states with resonant states of one's own. The activity of mirror neurons, and the fact that observers undergo motor facilitation in the same muscular groups as those utilized by target agents, are findings that accord well with simulation theory but would not be predicted by theory theory.     

Very long-term memory for odors: retention of odor-name associations.

The ability to remember odor-name associations for recent odors (those associated with everyday products experienced within the past 2 years) and distant odors (those associated with children's toys not encountered for 3 years or more) was examined in two experiments. In recognition tasks, subjects attempted to match odor names to odors, or odors to odor names. In a recall task, subjects tried to identify odors by name. The results showed that although odor retention was better for recent than distant odors, significant retention remains for odors not experienced since childhood. These results are consistent with other studies that found very slow and gradual loss of odor information in memory. They extend that research by showing that odor information is still available over a much longer period of time.
