How does the provision of semantic information influence the lexicalization of new spoken words?

The integration of a novel spoken word with existing lexical items can proceed within 24 hours of learning its phonological form. However, previous studies have reported that lexical integration of new spoken words can be delayed if semantic information is provided during learning. One possibility is that this delay in lexical integration reflects reduced phonological processing during learning as a consequence of the need to learn the semantic associations. In the current study, adult participants learnt novel words via a phoneme monitoring task, in which half of the words were associated with a picture referent, and half were phonological forms only. Critically, participants were instructed to learn the forms of the novel words, with no explicit goal to learn the word–picture mappings. Results revealed significant lexical competition effects emerging one week after consolidation, which were equivalent for the picture-present and form-only conditions. Tests of declarative memory and shadowing showed equivalent performance for picture-present and form-only words, despite participants showing good knowledge of the picture associations immediately after learning. These data support the contention that provided phonological information is recruited sufficiently well during learning, the provision of semantic information does not slow the time-course of lexical integration.     

The semantic origins of word order

Where do the different sentence orders in the languages of the world come from? Recently, it has been suggested that there is a basic sentence order, SOV (Subject–Object–Verb), which was the starting point for other sentence orders. Backup for this claim was found in newly emerging languages, as well as in experiments where people are asked to convey simple meanings in improvised gesture production. In both cases, researchers found that the predominant word order is SOV. Recent literature has shown that the pragmatic rule ‘Agent first’ drives the preference for S initial word order, but this rule does not decide between SOV and SVO. This paper presents experimental evidence for grounding the word order that emerges in gesture production in semantic properties of the message to be conveyed. We focus on the role of the verb, and argue that the preference for SOV word order reported in earlier experiments is due to the use of extensional verbs (e.g. throw). With intensional verbs like think, the object is dependent on the agent’s thought, and our experiment confirms that such verbs lead to a preference for SVO instead. We conclude that the meaning of the verb plays a crucial role in the sequencing of utterances in emerging language systems. This finding is relevant for the debate on language evolution, because it suggests that semantics underlies the early formation of syntactic rules.     

The acquisition of morphological knowledge investigated through artificial language learning

Affix knowledge plays an important role in visual word recognition, but little is known about how it is acquired. The authors present a new method of investigating the acquisition of affixes in which participants are trained on novel affixes presented in novel word contexts (e.g., sleepnept). Experiment 1 investigated the role of semantic information on affix acquisition by comparing a form-learning condition with a condition in which participants also received definitions for each novel word. Experiment 2 investigated the role of long-term consolidation on affix acquisition by comparing knowledge of learned affixes two days and nearly two months after training. Results demonstrated that episodic knowledge of affixes can be acquired shortly after a single training session using either form or semantic learning, but suggested that the development of lexicalized representations of affixes requires the provision of semantic information during learning as well as a substantial period of offline consolidation.     

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.     

The Case Against Objective Values

While objective values need not be intrinsically motivating, need not actually motivate us, they would determine what we ought to pursue and protect. They would provide reasons for actions. Objective values would come in degrees, and more objective value would provide stronger reasons. It follows that, if objective value exists, we ought to maximize it in the world. But virtually no one acts with that goal in mind. Furthermore, objective value would exist independently of our subjective valuings. But we have no way of measuring amounts of such values independently of the ways we value objects. While a subjectivist can account for mistaken values, a fully impersonal viewpoint, from which objective values would appear, seems instead to cause all values to disappear. Nor does the moral point of view, which requires more impartiality than agents usually exhibit, reveal fully objective values. The paper closes with an examination of the most widely endorsed candidates for states having positive and negative objective values: pleasures and pains. It concludes again that, once we adjust for worthiness of the object and desert of the subject for such states, there is no way to measure their supposed objective value.     

"Hay que ponerse en los zapatos del joven": adaptive parenting of adolescent children among Mexican-American parents residing in a dangerous neighborhood

We examined parenting of adolescents with Consensual Qualitative Research analyses of five 90-minute focus groups with 45 Mexican immigrant parents residing in a high-crime and low-income neighborhood. Parents identified gangs as their major challenge in parenting. Relatedly, they endorsed control-oriented practices to ensure the safety of their adolescents. In addition, parents used practices that aimed to build strong, trusting relationships with their adolescents. The co-occurrence of parenting strategies that promote strong parent-adolescent bonds along with strict monitoring highlights the need to conceptualize parenting with both controlling as well as supportive dimensions. Moreover, the parents' narratives pertaining to the dangers in their neighborhood suggest that interventions for Latino families should be not only consistent with their cultural heritage, but also grounded in the families' local neighborhood contexts.     

Shared ancestry, evolving stories: similar and contrasting life experiences described by foreign born and U.S. born Latino parents

As the Latino population in the United States continues to increase, so does the necessity for in-depth knowledge about their life experiences. This qualitative study sought to privilege the voices of Latino parents by utilizing focus group discussions. Specifically, participants described the life experiences that have the greatest influence on their parenting efforts. Similar and contrasting themes were identified based on participant country of origin (i.e., foreign born vs. U.S. born). Findings described the participants' commitment to being good parents, as well as the ways in which their parenting efforts are influenced by experiences of adversity and discrimination, Latino cultural values, gender roles, and resilience. The results of this investigation can inform researchers and mental health professionals working with Latino families.     

What makes words sound similar?

Although similarity plays an important role in accounts of language processing, there are surprisingly few direct empirical studies of the phonological similarity between words, and it is therefore not clear whether similarity comparisons between words involve processes similar to those involved in other cognitive domains. In five experiments, participants chose which of two monosyllabic pseudo-words sounded more similar to a target pseudo-word. Our results are generally consistent with the structural alignment theory of comparisons between complex mental representations, suggesting that phonological word similarity parallels similarity involving other kinds of information including visual objects and scenes, events, and word meanings. We use our results to test new metrics of word similarity, and identify predictions for future similarity research both in the domain of word sounds and in other cognitive domains.     

From semantics to syntax and back again: argument structure in the third year of life

An essential part of the human capacity for language is the ability to link conceptual or semantic representations with syntactic representations. On the basis of data from spontaneous production, suggested that young children acquire such links on a verb-by-verb basis, with little in the way of a general understanding of linguistic argument structure. Here, we suggest that a receptive understanding of argument structure--including principles linking syntax and conceptual/semantic structure--appears earlier. In a forced-choice pointing task we have shown that toddlers in the third year of life can map a single scene (involving a novel causative action paired with a novel verb) onto two distinct syntactic frames (transitive and intransitive). This suggests that even before toddlers begin generalizing argument structure in their own speech, they have some representation of conceptual/semantic categories, syntactic categories, and a system that links the two.     

Valuing myself over others: The Dark Triad traits and moral and social values

In samples from America and Germany (N = 1353), we examined how the Dark Triad traits related to different value systems as measured by Moral Foundations and Social Values. Psychopathy was linked to diminished concerns for all Moral Foundations, Machiavellianism was linked to a moral flexibility, and narcissism was linked to a socially desirable form of morality. Machiavellianism and psychopathy scores were associated with a devaluing of collective interests, whereas narcissism was associated with a valuing of individual interests through the value of Self-Enhancement. Individual differences in a variety of values mediated part of the sex differences in the Dark Triad traits. We contend that what makes the Dark Triad traits unique and interesting is that they share a unique complex of values that might run counter to societal expectations for selflessness.     

Designer testing: using subjects'' personal vocabulary to produce individualised tests

The principle of designer tests is that of using a subject's own semantics rather than lists of words that may or may not be relevant or even understandable for the subject. The Personalised Emotional Index (PEI) is a prototype designer test, in this case a mood test, that uses words that the subject chooses from a list of suggestions within mood categories. Each person's test is custom made from familiar and understandable words from his/her own vocabulary. Such a test has much face validity, can be succinct and has comprehensibility for the subject. The results obtained when using this test at the same time as the Profile of Mood States Bipolar Version (POMS-BI) were very similar (e.g. in a regression analysis, the ‘elated-depressed' variable predicted present overall mood on both tests (POMS: t=5.25, p<0.000, PEI: t=5.84, p<0.000) with a high correlation for total scores (r=0.82, p<0.000). The PEI results were correlated within the two week interval (r's about −0.74; p<0.000) and reasonably but not highly correlated on retesting some months after the first testing (r's about −0.25; p<0.000). It was successfully used to differentiate mood variables from a group consisting of caregivers of people with schizophrenia (n=30, producing 399 days of data) and a group of unselected controls (n=62, producing 1080 days of data). The test appears to have validity, reliability, comparability, and utility.     

Morphological learning in a novel language: A cross-language comparison

Being able to extract and interpret the internal structure of complex word forms such as the English word dance+r+s is crucial for successful language learning. We examined whether the ability to extract morphological information during word learning is affected by the morphological features of one's native tongue. Spanish and Finnish adult participants performed a word–picture associative learning task in an artificial language where the target words included a suffix marking the gender of the corresponding animate object. The short exposure phase was followed by a word recognition task and a generalization task for the suffix. The participants' native tongues vary greatly in terms of morphological structure, leading to two opposing hypotheses. On the one hand, Spanish speakers may be more effective in identifying gender in a novel language because this feature is present in Spanish but not in Finnish. On the other hand, Finnish speakers may have an advantage as the abundance of bound morphemes in their language calls for continuous morphological decomposition. The results support the latter alternative, suggesting that lifelong experience on morphological decomposition provides an advantage in novel morphological learning.
