Perceptual Bias in Speech Error Data Collection: Insights from Spanish Speech Errors

This paper studies the reliability and validity of naturalistic speech errors as a tool for language production research. Possible biases when collecting naturalistic speech errors are identified and specific predictions derived. These patterns are then contrasted with published reports from Germanic languages (English, German and Dutch) and one Romance language (Spanish). Unlike findings in the Germanic languages, Spanish speech errors show many patterns which run contrary to those expected from bias: (1) more phonological errors occur between words than within word; (2) word-initial consonants are less likely to participate in errors than word-medial consonants, (3) errors are equally likely in stressed and in unstressed syllables, (4) perseverations are more frequent than anticipations, and (5) there is no trace of a lexical bias. We present a new corpus of Spanish speech errors collected by many theoretically naïve observers (whereas the only corpus available so far was collected by two highly trained theoretically informed observers), give a general overview of it, and use it to replicate previous reports. In spite of the different susceptibility of these methods to bias, results were remarkably similar in both corpora and again contrary to predictions from bias. As a result, collecting speech errors “in the wild” seems to be free of bias to a reasonable extent even when using a multiple-collector method. The observed contrasting patterns between Spanish and Germanic languages arise as true cross-linguistic differences.     

Two Case Studies of Community Schools Serving Latino and Southeast Asian Children

Recent attention has focused on establishing school-based integrated services centers which offer educational and noneducational services to students and their families. We present two comparative case studies of client participation in school centers established in low income Latino and Southeast Asian communities. The cases focus on types of center services utilized by families, culturally compatible practices of the centers, and impact of coordinated services on students and families. The data reveal the limited capacity of high poverty families to cope with daily and persistent life challenges and how the schools have been transformed into family support environments which assist families to manage their lives in ways that lead to self-sufficiency and growth.     

Referral Source Differences in Functional Impairment Levels for Children Served in the Comprehensive Community Mental Health Services for Children and Their Families Program

We report one of the first multi-site investigations into referral source variation in functional impairment for children with serious emotional disturbance served in systems of care settings. Baseline data collected as part of the national evaluation for the Comprehensive Community Mental Health Services for Children and Their Families Program was used to assess the comparability of functional status for children referred from traditional mental health versus non-mental health agencies. Results indicate that children referred from child welfare and family groups have significantly lower levels of overall dysfunction than those referred from mental health, while children referred from school and juvenile justice agencies have comparable levels. Clinical and research implications are discussed.     

Illusions of Optimal Motion,Relationism, and Perceptual Content

Austere relationism rejects the orthodox analysis of hallucinations and illusions as incorrect perceptual representations. In this article, I argue that illusions of optimal motion (IOMs) present a serious challenge for this view. First, I submit that austere‐relationist accounts of misleading experiences cannot be adapted to account for IOMs. Second, I show that any attempt at elucidating IOMs within an austere‐relationist framework undermines the claim that perceptual experiences fundamentally involve relations to mind‐independent objects. Third, I develop a representationalist model of IOMs. The proposed analysis combines two ideas: Evans' dynamic modes of presentation and Fine's relational semantics for identity.     

Monkey memory: same/different concept learning, serial probe acquisition, and probe delay effects

Three rhesus monkeys were trained and tested in a same/different task with six successive sets of 70 item pairs to an 88% accuracy on each set. Their poor initial transfer performance (55% correct) with novel stimuli improved dramatically to 85% correct following daily item changes in the training stimuli. They acquired a serial-probe-recognition (SPR) task with variable (1-6) item list lengths. This SPR acquisition, although gradual, was more rapid for the monkeys than for pigeons similarly trained. Testing with a fixed list length of four items at different delays between the last list item and the probe test item revealed changes in the serial-position function: a recency effect (last items remembered well) for 0-s delay, recency and primacy effects (first and last list items remembered well) for 1-, 2-, and 10-s delays, and only a primacy effect for the longest 30-s delay. These results are compared with similar ones from pigeons and are discussed in relation to theories of memory processing.     

Be a Mom: Formative Evaluation of a Web-Based Psychological Intervention to Prevent Postpartum Depression

A formative evaluation (consisting of two phases: a scoping literature review and a focus group with mental health professionals) was conducted to inform the design of a web-based intervention to prevent postpartum depression, in terms of its characteristics and content: the Be a Mom program. The results showed that the web-based intervention should be short-term, delivered postnatally, and grounded in cognitive-behavior therapy principles. Moreover, the intervention should include weekly sessions targeting basic contents: motherhood changes, reorganizations and emotional experience; cognitions, self-criticism, and self-compassion; parenting values, social support, and assertive communication skills; couple relationship, negotiation and conflict resolution skills; and postpartum depression signs and professional help-seeking. These results may improve the Be a Mom’s adequacy, implementation success, and effectiveness.     

Mechanisms of visuospatial orienting in deafness

The aim of this work was to explore the nature of elementary operations (engage, move, disengage, and filtering) of spatial attention in deaf experts in sign language. Good communication skills require deaf people to rapidly change attention to at least two separate spatial locations, the facial expression and the hand signs of the speaker. Overtraining imposed by sign language demands might have modified certain characteristics of the spatial attention operations. To test that, a spatial orienting task was used in two experiments. Experiment 1 showed that deaf subjects reoriented their attention to the target location faster than hearing subjects in invalid trials. Experiment 2 indicated that inhibition of return decays faster in deaf than in hearing people. These results suggest that deaf subjects can disengage their attention faster than hearing subjects, fostering search of relevant information in more spatial locations.     

Amitriptyline administered after consolidation of inhibitory avoidance does not affect memory retrieval

In Experiment 1, the effect of the administration of the antidepressant amitriptyline (30 mg/kg) for 21 days on the acquisition and consolidation of the inhibitory avoidance task was studied in male and female mice. In Experiment 2, it was evaluated whether amitriptyline administered after the consolidation of this task would block the memory retrieval. Anxiety and spontaneous activity in the elevated plus maze were also assessed. When amitriptyline was given before the training phase of inhibitory avoidance it blocked learning in males and there was a tendency in the same direction in females. However, the drug administered between training and test phases did not affect conditioning. These effects of amitriptyline seem to be independent of its actions on anxiety and locomotor activity. It may be that the effects observed are related to the therapeutic effects of antidepressants.     

Retrieval-induced forgetting in recall and recognition of thematically related and unrelated sentences

In three experiments, we assessed the effects of type of relation and memory test on retrieval-induced forgetting of facts. In Experiments 1 and 2, eight sets of four shared-subject sentences were presented for study. They were constructed so that half were thematically related and half were unrelated. A retrieval practice phase required participants to recall a subset of the studied sentences. In the final test, the participants were prompted to recall all the sentences (character cued in Experiment 1 and character plus stem cued in Experiment 2). The results showed that the retrieval-induced forgetting (RIF) effect was similar for thematically related and unrelated sentences, indicating that the presence of episodic relations among the sentences was sufficient to produce the effect. In Experiment 3, a recognition task was introduced and the RIF effect emerged in accuracy as well as in latency measures. The presence of this effect with item-specific cues is difficult to accommodate for noninhibitory theories of retrieval.
