The developing role of prosody in novel word interpretation

This study examined whether children use prosodic correlates to word meaning when interpreting novel words. For example, do children infer that a word spoken in a deep, slow, loud voice refers to something larger than a word spoken in a high, fast, quiet voice? Participants were 4- and 5-year-olds who viewed picture pairs that varied along a single dimension (e.g., big vs. small flower) and heard a recorded voice asking them, for example, “Can you get the blicket one?” spoken with either meaningful or neutral prosody. The 4-year-olds failed to map prosodic cues to their corresponding meaning, whereas the 5-year-olds succeeded (Experiment 1). However, 4-year-olds successfully mapped prosodic cues to word meaning following a training phase that reinforced children’s attention to prosodic information (Experiment 2). These studies constitute the first empirical demonstration that young children are able to use prosody-to-meaning correlates as a cue to novel word interpretation.     

An Evaluation of the Psychometric Properties of the Womanist Identity Attitudes Scale

Responses from 101 African American/Black and 100 White women were used to examine the psychometric properties of the Womanist Identity Attitudes Scale (WIAS; Ossana, 1986; Ossana, Helms, & Leonard, 1992). First, internal consistency reliabilities suggested the need for further development of 3 of the 4 WIAS subscales. Second, links between WIAS scores and (a) sexist, (b) hostile sexist attitudes toward women, (c) benevolently sexist attitudes toward women, and (d) egalitarian attitudes toward women's rights and roles provided mixed support for the convergent validity of the WIAS. Third, consistent with theoretical conceptualization, the intercorrelations among WIAS subscales were similar for African American/Black and White women. These intercorrelations, however, were not entirely consistent with the theorized developmental process of the womanist identity model. Finally, the structural validity of the WIAS was examined using confirmatory and exploratory factor-analytic procedures. Both sets of analyses challenged the fit of the theorized womanist identity development model with data produced by the WIAS.     

Religious Orthodoxy and the Complexity of Thought about Religious and Nonreligious Issues

Two studies examined the relationship between religious orthodoxy and the complexity of thinking about religious and nonreligious issues. In both studies, participants who were high or low in religious orthodoxy wrote a paragraph outlining their thoughts about a religious issue (life after death in Study 1; existence of God in Study 2) and/or a nonreligious issue (capital punishment in Study 1; free trade between Canada and the U.S. in Study 2). The results of both studies indicated that participants who were high in religious orthodoxy were less complex in their thinking about religious issues than those low in religious orthodoxy, but did not differ in the complexity of their thinking about nonreligious issues. These results do not support the notion that orthodoxly religious individuals are dispositionally inclined to think in simpler or more rigid ways overall, but they do suggest a tendency to think less complexly about religious issues.     

The semantics of prosody: acoustic and perceptual evidence of prosodic correlates to word meaning

This investigation examined whether speakers produce reliable prosodic correlates to meaning across semantic domains and whether listeners use these cues to derive word meaning from novel words. Speakers were asked to produce phrases in infant-directed speech in which novel words were used to convey one of two meanings from a set of antonym pairs (e.g., big/small). Acoustic analyses revealed that some acoustic features were correlated with overall valence of the meaning. However, each word meaning also displayed a unique acoustic signature, and semantically related meanings elicited similar acoustic profiles. In two perceptual tests, listeners either attempted to identify the novel words with a matching meaning dimension (picture pair) or with mismatched meaning dimensions. Listeners inferred the meaning of the novel words significantly more often when prosody matched the word meaning choices than when prosody mismatched. These findings suggest that speech contains reliable prosodic markers to word meaning and that listeners use these prosodic cues to differentiate meanings. That prosody is semantic suggests a reconceptualization of traditional distinctions between linguistic and nonlinguistic properties of spoken language.
