Similarity relations among spoken words: The special status of rimes in English

This paper presents an analysis of the distribution of phonological similarity relations among monosyllabic spoken words in English. It differs from classical analyses of phonological neighborhood density (e.g., Luce &; Pisoni, 1998) by assuming that not all phonological neighbors are equal. Rather, it is assumed that the phonological lexicon has psycholinguistic structure. Accordingly, in addition to considering thenumber of phonological neighbors for any given word, it becomes important to consider thenature of these neighbors. If one type of neighbor is more dominant, neighborhood density effects may reflect levels of segmental representation other than the phoneme, particularly prior to literacy. Statistical analyses of the nature of phonological neighborhoods in terms ofrime neighbors (e.g.,hat/cat),consonant neighbors (e.g.,hat/hit), andlead neighbors (e.g.,hat/ham) were thus performed for all monosyllabic words in the Celex corpus (4,086 words). Our results show that most phonological neighbors are rime neighbors (e.g.,hat/cat) in English. Similar patterns were found when a corpus of words for which age-of-acquisition ratings were available was analyzed. The resultant database can be used as a tool for controlling and selecting stimuli when the role of lexical neighborhoods in phonological development and speech processing is examined.     

The role of learning in remembered duration

In two experiments, the effects of learning on both the accuracy and bias of duration judgments were examined. In Experiment 1, subjects learned one of two tasks (i.e., using a computer software package, building a model car), containing a varying number of action steps, over a one-, three-, or five-trial period. Retrospective judgments of a task’s total duration revealed that accuracy was high at intermediate stages of learning but was low at early stages due to an overestimation bias and low at later stages due to an underestimation bias. The number of action steps within a task influenced behavior only at early learning stages where more action steps led to significantly longer duration estimates. Experiment 2 acted as a converging operation in which novice and experienced pianists were asked to estimate, in advance, how long they thought it would take them to play melodies that varied in their degree of familiarity (i.e. recently learned, well learned, extremely well learned). When these estimates were compared with the melodies’ actual playing times, results revealed a similar pattern of accuracy and bias as found in Experiment 1. These findings are discussed in terms of a “structural remembering model” that emphasizes the role of event predictability in time estimation behavior.     

Overcoming a Legacy of Conflict: The Repercussive Effects of Stress and Intergenerational Transmission of Trauma Among Vietnamese Americans

The modern narrative of Vietnamese people is often strongly associated with events of the 20th century, such as the Vietnam War, but a legacy of strife in Southeast Asia spans many centuries. Enduring stress and trauma has pernicious psychological and physiological repercussions that have affected first and later generations of Vietnamese American refugees. To contextualize the present-day narrative, we review the history of Vietnam and the contemporary refugee experience in the United States. We then examine more proximal spheres of influence, including community and family. Finally, we review individual experiences of stress and trauma. We present recommendations to inform individual, group, family, and community-based counseling interventions, as well as recommendations for future research.     

Time to get a new mountain? The role of function in children's conceptions of natural kinds

Prior research indicates that young children are promiscuously teleological, attributing purpose not only to artifacts, but also to living and non-living natural entities. This study further examines the role of function in children's reasoning about different object kinds by indirectly probing children's intuitions about what types of entities can be rendered functionless. Specifically, children were asked to decide whether entities that could no longer perform certain activities should be fixed/replaced (e.g. "Do you need to get a new one?"). Results reveal that young children broadly view both artificial and natural kinds that can no longer perform certain activities as needing to be fixed or replaced. These findings suggest that the teleo-functional bias not only influences children's explanatory preferences but also their category judgments.     

Neighborhood Violence and Psychosocial Adjustment in Low-Income Urban African American Children: Physical Symptoms as a Marker of Child Adjustment

We examined the association between neighborhood violence and three domains of psychosocial adjustment in low-income, urban African American children: internalizing, externalizing, and physical symptoms. Based on anecdotal and empirical evidence, it was hypothesized that, relative to internalizing and externalizing problems, a stronger association would emerge between physical symptoms and neighborhood violence. Mother-reported neighborhood violence was associated with child-reported physical symptoms, but not internalizing or externalizing symptoms. Child-reported neighborhood violence was associated with child-reported internalizing, externalizing, and physical symptoms; however, neighborhood violence accounted for a greater percentage of variance in physical symptoms than the other two symptom domains. Our findings were not moderated by the age or gender of the child. We discuss the importance of physical symptoms as a marker of child adjustment in low-income, urban, African American children, as well directions for future research.     

Depressed Adolescents and Comorbid Psychiatric Disorders: Are There Differences in the Presentation of Depression?

Patterns and correlates of comorbidity, as well as differences in manifest depressive profiles were investigated in a sample of depressed adolescents. A sub-sample of the youth were characterized as belonging to either a Pure depression group, an Internalizing group (depression and co-occurring internalizing disorders), or an Externalizing group (depression and co-occurring externalizing disorders). Item response theory (IRT) and differential item functioning (DIF) were used to assess whether the depressed adolescents from the different comorbidity groups presented with different depressive symptoms. Results indicated that the comorbidity groups were meaningfully distinct in terms of psychosocial correlates as well as showed differences in depressive symptom profiles as informed by DIF analyses. In particular, the comorbidity groups differed in terms of presentation of psychomotor changes and cognitive impairments. Implications for assessment are discussed.

Appearances aren't everything: shape classifiers and referential processing in Cantonese

Cantonese shape classifiers encode perceptual information that is characteristic of their associated nouns, although certain nouns are exceptional. For example, the classifier tiu occurs primarily with nouns for long-narrow-flexible objects (e.g., scarves, snakes, and ropes) and also occurs with the noun for a (short, rigid) key. In 3 experiments, we explored how the semantic information encoded in shape classifiers influences language comprehension. When judging the fit between classifiers and depicted objects in an explicit ranking task, Cantonese speakers evaluated classifier-noun pairings solely in terms of grammatical well-formedness and showed no separate sensitivity to the shape features of objects. In an eye-tracking task (Experiment 2), we also found little sensitivity to shape classifier semantics during real-time comprehension. However, in a subsequent experiment in which referent objects lacked the prototypical features for their accompanying classifiers (Experiment 3), an influence of shape semantics was found in participants' incidental fixations to nontarget objects. We conclude that shape classifiers influence referential interpretation primarily through their grammatical constraints, consistent with the agreementlike nature of classifiers in general. The role of shape classifiers' semantics on processing is apparent only in specific circumstances.     

Spatial Reversal as a Measure of Executive Functioning in Children With Autism

The purpose of this experiment was to compare the executive functioning performance of children with autism with chronological- and verbal-matched controls in a spatial-reversal task. Three groups of children participated in this experiment. One group was identified as having autism (7 boys), the 2nd group contained 7 typically developing children (6 boys, 1 girl) who were matched to the 1st group based on their verbal performance, and the 3rd group contained 7 typically functioning children (6 boys, 1 girl) matched to the 1st group based on chronological age. Each group was given a spatial-reversal task containing 2 problems. In the 1st problem, children selected a toy on a particular side in a pair. In the 2nd problem, the contingencies were reversed such that children were to choose the toy on the opposite side. Children with autism generally performed worse than comparison groups as indicated by their overall higher rate of errors. However, these results must be qualified by considering the performance for each problem: Errors for the children with autism were infrequent during the 1st problem but increased in the 2nd, whereas errors for comparison children showed the opposite pattern. When these results from the spatial-reversal task were intérpreted from the perspective of hypothesis-testing theory, the executive functioning deficiency of children with autism was found to involve the selection and testing of stereotypic response sets that were not likely to be revised or changed flexibly according to feedback from the environment or the demands of the task.     

An evaluation of textual prompts and generalized textual instruction‐following

The benefit of permanent prompts depends on the extent to which their use is generalized. Previous research has demonstrated both control by and efficacy of pictorial prompts (e.g., Phillips & Vollmer, 2012). The present studies similarly evaluated stimulus control by textual prompts. Six school aged children with intellectual disabilities were taught to complete four 5‐step instructional sets under the control of textual prompts. All 6 subjects showed some generalization to the final set. The results suggest that training served 1 of 3 purposes: (a) established control by the textual prompts or the ordinal sequence thereof, (b) addressed a reading deficit, or (c) addressed the lack of a motivating operation during baseline. Training a single task sequence may not be sufficient for acquisition of generalized textual instruction‐following. However, establishing appropriate stimulus control by the textual prompts may facilitate acquisition of a generalized repertoire.     

Norming the odd: Creation,norming, and validation of a stimulus set for the study of incongruities across music and language

Research into similarities between music and language processing is currently experiencing a strong renewed interest. Recent methodological advances have led to neuroimaging studies presenting striking similarities between neural patterns associated with the processing of music and language—notably, in the study of participants’ responses to elements that are incongruous with their musical or linguistic context. Responding to a call for greater systematicity by leading researchers in the field of music and language psychology, this article describes the creation, selection, and validation of a set of auditory stimuli in which both congruence and resolution were manipulated in equivalent ways across harmony, rhythm, semantics, and syntax. Three conditions were created by changing the contexts preceding and following musical and linguistic incongruities originally used for effect by authors and composers: Stimuli in the incongruous–resolved condition reproduced the original incongruity and resolution into the same context; stimuli in the incongruous–unresolved condition reproduced the incongruity but continued postincongruity with a new context dictated by the incongruity; and stimuli in the congruous condition presented the same element of interest, but the entire context was adapted to match it so that it was no longer incongruous. The manipulations described in this article rendered unrecognizable the original incongruities from which the stimuli were adapted, while maintaining ecological validity. The norming procedure and validation study resulted in a significant increase in perceived oddity from congruous to incongruous–resolved and from incongruous–resolved to incongruous–unresolved in all four components of music and language, making this set of stimuli a theoretically grounded and empirically validated resource for this growing area of research.
