Effects of children’s hearing loss on the synchrony between parents’ object naming and children’s attention

Children’s attentional state during parent-child interactions is important for word learning. The current study examines the real-time attentional patterns of toddlers with and without hearing loss (N = 15, age range: 12–37 months) in parent-child interactions. High-density gaze data recorded from head-mounted eye-trackers were used to investigate the synchrony between parents’ naming of novel objects and children’s sustained attention on the named objects in joint play. Results show that the sheer quantities of parents’ naming and children’s sustained attention episodes were comparable in children with hearing loss and their peers with normal hearing. However, parents’ naming and children’s sustained attention episodes were less synchronized in the hearing loss group compared to children with normal hearing. Possible implications are discussed.     

The Sounds of Silence: Inferences from the Absence of Word‐of‐Mouth

While past work has explored some of the reasons why people themselves may remain silent in a group, almost no research has examined the mirror image of this question: How do consumers construe the silence of others? Do they project the opinions of the speakers in a conversation onto the silent individuals, assuming that silence signals agreement? Do they have a usual or “default” naïve theory of silence that they use to explain it across multiple contexts—i.e., “silence usually signals disagreement?” Or does silence act as a mirror, reflecting observers’ own opinions back at them? Three experiments contrasted perceivers’ estimates of conversational silence with their estimates of unknown opinions outside the conversation. Estimates of opinions outside the conversation generally followed an agreement‐with‐the‐speakers rule—the more an opinion was expressed in the group, the more consumers assumed others would support it too. In contrast, silence inside the conversation was interpreted very differently, serving as a mirror for participants’ own thoughts, even when the vocal majority favored the opposite position. Results suggest a process whereby observers project the reason they personally would have been silent in the group (given their opinion) onto silence, leading to an inference that the silents agree with the self.     

Reading and lexicalization in opaque and transparent orthographies: Word naming and word learning in English and Spanish

Do skilled readers of opaque and transparent orthographies make differential use of lexical and sublexical processes when converting words from print to sound? Two experiments are reported, which address that question, using effects of letter length on naming latencies as an index of the involvement of sublexical letter–sound conversion. Adult native speakers of English (Experiment 1) and Spanish (Experiment 2) read aloud four- and seven-letter high-frequency words, low-frequency words, and nonwords in their native language. The stimuli were interleaved and presented 10 times in a first testing session and 10 more times in a second session 28 days later. Effects of lexicality were observed in both languages, indicating the deployment of lexical representations in word naming. Naming latencies to both words and nonwords reduced across repetitions on Day 1, with those savings being retained to Day 28. Length effects were, however, greater for Spanish than English word naming. Reaction times to long and short nonwords converged with repeated presentations in both languages, but less in Spanish than in English. The results support the hypothesis that reading in opaque orthographies favours the rapid creation and use of lexical representations, while reading in transparent orthographies makes more use of a combination of lexical and sublexical processing.     

Shock and awe: Distinct effects of taboo words on lexical decision and free recall

Taboo stimuli are highly arousing, but it has been suggested that they also have inherent taboo-specific properties such as tabooness, offensiveness, or shock value. Prior studies have shown that taboo words have slower response times in lexical decision and higher recall probabilities in free recall; however, taboo words often differ from other words on more than just arousal and taboo properties. Here, we replicated both of these findings and conducted detailed item analyses to determine which word properties drive these behavioural effects. We found that lexical-decision performance was best explained by measures of lexical accessibility (e.g., word frequency) and tabooness, rather than arousal, valence, or offensiveness. However, free-recall performance was primarily driven by emotional word properties, and tabooness was the most important emotional word property for model fit. Our results suggest that the processing of taboo words is influenced by distinct sets of factors and by an intrinsic taboo-specific property.     

The influence of speech rate and accent on access and use of semantic information

Circumstances in which the speech input is presented in sub-optimal conditions generally lead to processing costs affecting spoken word recognition. The current study indicates that some processing demands imposed by listening to difficult speech can be mitigated by feedback from semantic knowledge. A set of lexical decision experiments examined how foreign accented speech and word duration impact access to semantic knowledge in spoken word recognition. Results indicate that when listeners process accented speech, the reliance on semantic information increases. Speech rate was not observed to influence semantic access, except in the setting in which unusually slow accented speech was presented. These findings support interactive activation models of spoken word recognition in which attention is modulated based on speech demands.     

Evangelism Challenges the Church's Identity

The gospel of Christ has spread to hundreds of linguistic and cultural communities. Christian churches have come face to face with an extraordinarily positive but nevertheless perplexing problem: Can the churches find the common core message of the holistic gospel or will the actual content of faith become relativized into the interpretation of interpretations? Despite the many different definitions of evangelism/evangelization, evangelism always leads to consideration of the basic questions of faith: its profound understanding and its reception. Evangelism involves the questions of what I believe or believe in, and of what I commit to. In the midst of the constant flow of information and the hectic tempo of life, evangelism challenges the church again and again to reconsider how the gospel can be expressed compactly, but in a rich, understandable, and true‐to‐life way. In the ecumenical discussion, the concept of “witness” as a form of evangelism is becoming increasingly important, because it comprises all the essential dimensions of the whole gospel. Evangelism challenges churches and their members to boldly bear witness by word and deed to Jesus Christ.     

A Bootstrapping Model of Frequency and Context Effects in Word Learning

Prior research has shown that people can learn many nouns (i.e., word–object mappings) from a short series of ambiguous situations containing multiple words and objects. For successful cross‐situational learning, people must approximately track which words and referents co‐occur most frequently. This study investigates the effects of allowing some word‐referent pairs to appear more frequently than others, as is true in real‐world learning environments. Surprisingly, high‐frequency pairs are not always learned better, but can also boost learning of other pairs. Using a recent associative model (Kachergis, Yu, & Shiffrin, 2012), we explain how mixing pairs of different frequencies can bootstrap late learning of the low‐frequency pairs based on early learning of higher frequency pairs. We also manipulate contextual diversity, the number of pairs a given pair appears with across training, since it is naturalistically confounded with frequency. The associative model has competing familiarity and uncertainty biases, and their interaction is able to capture the individual and combined effects of frequency and contextual diversity on human learning. Two other recent word‐learning models do not account for the behavioral findings.     

"The End of all our Exploring" in Science and Theology

Abstract. The present malaise of religion—and of theology, its intellectual formulation—in Western society is analyzed, with some personal references, especially with respect to its history in the United Kingdom and the United States. The need for a more open theology that takes account of scientific perspectives is urged. An indication of the understandings of God and of God's relation to the world which result from an exploration starting from scientific perspectives is expounded together with their fruitful relation to some traditional themes. The implications of this for the future of theology are suggested, not least in relation to the new phase, beginning in 2003, of the development of the Zygon Center for Religion and Science. In a concluding reflection the hope is expressed that the shared global experience and perspectives generated by the sciences might form a more common and acceptable starting point than hitherto for the exploration towards God of the seekers of many religious traditions and of none.
