Processing of Syllables in Production and Recognition Tasks

Empirical evidence for a functional role of syllables in visual word processing is abundant, however it remains rather heterogeneous. The present study aims to further specify the role of syllables and the cognitive accessibility of syllabic information in word processing. The first experiment compared performance across naming and lexical decision tasks by manipulating the number of syllables in words and non-words. Results showed a syllable number effect in both the naming task and the lexical decision task. The second experiment introduced a stimulus set consisting of isolated syllabic and non-syllabic trigrams. Syllable frequency was manipulated in a naming and in a decision task requiring participants to decide on the syllabic status of letter strings. Results showed faster responses for syllables than for non-syllables in both tasks. Syllable frequency effects were observed in the decision task. In summary, the results from these manipulations of different types of syllable information confirm an important role of syllabic units in both recognition and production.     

How predictable is spelling? Developing and testing metrics of phoneme-grapheme contingency

Prior research has purported to show that words with infrequent phoneme-grapheme correspondences are more difficult to spell than words with frequent phoneme-grapheme correspondences. Defining exactly what a phoneme-grapheme relationship is, however, is not necessarily straightforward. There are a number of different assumptions that can be made. In this study, we developed four metrics of sound-spelling contingency based on all monosyllabic English words, including those with complex morphology. These metrics differed in the extent to which they included assumptions about spelling. The psychological reality of these different metrics was evaluated against data from a large-scale study of skilled adult spelling and a nonword spelling experiment. The results suggest that when spelling, people are sensitive to positional information, morphological status, vowel type, and a number of more idiosyncratic constraints.     

Masculinity and femininity: The role of desirability in the relationships among measures based on self-concept and personality traits

With data gathered from 96 female college students, intercorrelations were examined among self-concept ratings of masculinity and femininity, and scales from two personality-trait measures of masculinity and femininity—the Adjective Check List (ACL) and the Extended Personal Attributes Questionnaire (EPAQ). The sign and magnitude of the correlations between pairs of measures were successfully predicted on the basis of the congruence between measures of both the gender relevance and the desirability of the self-rated traits comprising each measure. The desirability of the trait items employed in self-report personality-trait scales of masculinity and femininity evidently introduces methods variance that can either inhibit or potentiate the relationship with other scales composed predominantly of either desirable or undesirable traits. When balanced for the desirability of trait items, personality-trait scores of masculinity and femininity were substantially inversely correlated with each other, and only marginally correlated with self-concept ratings of masculinity and femininity, but these correlations remained in the anticipated directions. This result is consistent with the findings of Pedhazur and Tetenbaum (“Bem Sex Role Inventory: A Theoretical and Methodological Critique,” Journal of Personality and Social Psychology, 1979, 37, 996–1016), and supports Spence's (Masculinity, Femininity, and Gender-Related Traits: A Conceptual Analysis and Critique of Current Research,” In B. A. Maher and W. B. Maher (Eds.), Progress in Experimental Research, Vol. XIII, Normal Personality Processes, New York: Academic Press, 1984) position that personality traits should be viewed as only one of many possible referents for gender/sex role identity.     

Parts of activities: reply to Fellbaum and Miller (1990)

If people believe that one activity is a kind of another, they also tend to believe that the second activity is a part of the first. For example, they assert that deciding is a kind of thinking and that thinking is a part of deciding. Fellbaum and Miller's (1990) explanation for this phenomenon is based on the idea that people interpret part of in the domain of verbs as a type of logical entailment. Their explanation, however, suffers from at least 2 deficiencies. First, it fails to account for parallel effects with nouns (e.g., a contest is a kind of an activity, and an activity is a part of a contest). Second, it contains a flaw that incorrectly predicts many activities to be parts of each other (e.g., coming is part of going and going part of coming). However, a hypothesis Rips and Conrad (1989) originally proposed for the kind-part reciprocal effect avoids both of these difficulties.     

The Papago Psychology Service: A community mental health program on an American Indian reservation

A community psychology service run by the Papago Indian tribe and staffed largely by Papago Indians who have been trained as mental health workers is described. This service is unique among mental health services for Indians in that the tribe has complete control of the funds for the service and sets its own policies. It was developed for a rather traditional Indian group, and the culture, the traditions, and the wishes of the Papago community were respected. Consultation with medicine men was built into the program from the start, and adaptation of mental health techniques to fit the culture is stressed. Before this clinic was established, few mental health resources were directly available to the reservation. Similar to other Indian tribes, the Papagos are economically disadvantaged, with an unemployment rate of over 50%, low educational attainment, and very high rates of alcoholism, suicide, and vehicular accidents. The topics covered are the tribe's view of health programs for its people, the present Papago community and traditional means of treatment, traditional psychotherapy adapted to Papago culture, the indigenous Papago mental health worker, and the non-Indian professional consultant.     

Folk psychology of mental activities

A central aspect of people's beliefs about the mind is that mental activities--for example, thinking, reasoning, and problem solving-- are interrelated, with some activities being kinds or parts of others. In common-sense psychology, reasoning is a kind of thinking and reasoning is part of problem solving. People's conceptions of these mental kinds and parts can furnish clues to the ordinary meaning of these terms and to the differences between folk and scientific psychology. In this article, we use a new technique for deriving partial orders to analyze subjects' decisions about whether one mental activity is a kind or part of another. The resulting taxonomies and partonomies differ from those of common object categories in exhibiting a converse relation in this domain: One mental activity is a part of another if the second is a kind of the first. The derived taxonomies and partonomies also allow us to predict results from further experiments that examine subjects' memory for these activities, their ratings of the activities' importance, and their judgements about whether there could be "possible minds" that possess some of the activities but not others.     

The role of the interpolated task in short-term retention

It has been proposed that a single set of operations based on classical interference theory is adequate to describe the phenomena of both short- and long-term memory. An article by Keppel and Underwood (1962) argues that short-term forgetting is due to proactive interference and, by implication, not a result of trace decay. An experiment which varied retention interval and the nature of the interpolated task, gave results which indicate that when the amount forgotten and the nature of errors are considered, a decay model is supported, the proactive interference suggestion being untenable.
