The Relationship

This study proposes a new methodology for determining the relationship between child-directed speech and child speech in early acquisition. It illustrates the use of this methodology in investigating the relationship between the morphological richness of child-directed speech and the speed of morphological development in child speech. Both variables are defined in terms of mean size of paradigm (MSP) and estimated in a set of longitudinal spontaneous speech corpora of nine children and their caretakers. The children are aged 1;3–3;0, acquiring nine different languages that vary in terms of morphological richness. The main result is that the degree of morphological richness in child-directed speech is positively related to the speed of development of noun and verb paradigms in child speech.

AbstractInterfaces between grammatical domains have been considered from various perspectives in child language research and in general linguistics. The study aims to provide evidence for interfaces in acquisition of early clause-structure, based on longitudinal data from three Hebrew-acquiring toddlers. Two facets of their early speech output were examined: Usage productivity in verb-inflection, identified by a criterion of contextual appropriateness; and structural transparency/opacity of children’s speech output, with transparent forms being unambiguous in relation to their grammatical targets. These factors yielded two distinct developmental periods for the three children: I – from the onset of verb usage to productive verb inflection, and II – from productive verb inflection to disappearance of structural opacity. Period II displays a puzzling mixture of both transparent and opaque usages, not only in verb inflection, but also in use of prepositions marking objects and adverbs. These puzzles are resolved by the significant correlations that emerged between apparently unrelated linguistic systems: (1) opaque verb-forms occur mainly together with object/adverbs, and (2) transparent prepositions occur mainly in combination with transparent verbs. These unexpected convergences between different linguistic systems are discussed as underlining the role of structural transparency/opacity and as shedding new light on between-domain interfaces in language acquisition.

Original Event

Two experiments investigated the role of inflections in verb learning. In Study I, 3- to 5-year-olds with typical language development were asked to extend novel verbs to new instances. They heard the verbs inflected with either -ed or -ing and were given a forced choice between events that maintained either the activity or the result of the original event. The younger children selected events according to the verb inflection: same-activity events for -ing and same-result events for -ed. Older preschoolers chose same-result events throughout. Study II was conducted to investigate the nature of this causal bias. A group of 4- to 5-year-olds with specific language impairment completed the same verb extension task. They were equivalent to the older Study I children in age and IQ but were at lower language levels than the younger group. Children in the SLI group used neither the inflectional strategy nor the same-result strategy. Findings from the two studies point to a developmental period during which children treat inflectional cues as reliable guides to verb meaning. The discussion focuses on the rise and fall of such inflectional bootstrapping and the linguistic character of the same-result bias that replaces it.

ABSTRACTThe acquisition of German participle inflection was investigated using spontaneous speech samples from six children between 1 ; 4 and 3 ; 8 and ten children between 1 ; 4 and 2 ; 10 recorded longitudinally at regular intervals. Child-directed speech was also analyzed. In adult and child speech weak participles were significantly more frequent than strong participles. Children's errors involved all elements of participle marking. All error types, including over-regularization, occurred from the beginning alongside correct forms. Errors decreased significantly over age. Over-regularization in the sense of -t affixation on strong verbs was significantly more frequent than erroneous -en suffixation on weak verbs but not than prefix and suffix omission. On participles with stem vowel change erroneous stem vowel was significantly more frequent than correct stem vowel with suffix error alone. Error patterns are explained in terms of frequencies, and participle inflection being learned as part of general verb inflection.

AbstractWhitehouse adapts insights from evolutionary anthropology to interpret extreme self-sacrifice through the concept of identity fusion. The model neglects the role of normative systems in shaping behaviors, especially in relation to violent extremism. In peaceful groups, increasing fusion will actually decrease extremism. Groups collectively appraise threats and opportunities, actively debate action options, and rarely choose violence toward self or others.

AbstractIntuitions guide decision-making, and looking to the evolutionary history of humans illuminates why some behavioral responses are more intuitive than others. Yet a place remains for cognitive processes to second-guess intuitive responses – that is, to be reflective – and individual differences abound in automatic, intuitive processing as well.

Sense Of Obligation

Abstract Tomasello offers a compelling account of the emergence of humans’ sense of obligation. We suggest that more needs to be said about the role of affect in the creation of obligations. We also argue that positive emotions such as gratitude evolved to encourage individuals to fulfill cooperative obligations without the negative quality that Tomasello proposes is inherent in obligations.
