Paternal influences in non-organic failure to thrive: Implications for psychosocial management

Clinical experience indicates that fathers have a salient influence on the development of non-organic failure to thrive (NOFT) infants and on the feeding and attachment disturbances that often accompany this pediatric condition. As shown in case examples, fathers influence the origins and outcomes of NOFT through their participation in maladaptive patterns of parenting and/or conflicts with the child's mother, which disrupt maternal emotional adjustment and maternal-child interactions. Clinical assessment of paternal influences through interview and observation can help formulate more realistic treatment planning and family-centered interventions for NOFT children.     

Acutely induced anxiety increases negative interpretations of events in a closed-circuit television monitoring task

In two experiments we measured the effects of 7.5% CO₂ inhalation on the interpretation of video footage recorded on closed circuit television (CCTV). As predicted, inhalation of 7.5% CO₂ was associated with increases in physiological and subjective correlates of anxiety compared with inhalation of medical air (placebo). Importantly, when in the 7.5% CO₂ condition, participants reported the increased presence of suspicious activity compared with placebo (Experiment 1), a finding that was replicated and extended (Experiment 2) with no concomitant increase in the reporting of the presence of positive activity. These findings support previous work on interpretative bias in anxiety but are novel in terms of how the anxiety was elicited, the nature of the interpretative bias, and the ecological validity of the task.     

Children's expectations and episodic reports over 12 weeks: Influences on memory for a specially designed pediatric examination

This investigation extended work on the linkage between knowledge and remembering by exploring the relation between generic and episodic memory representations. Thirty 6-year-old children experienced a mock physical examination with some expected components omitted and other unexpected actions included. Immediately and again after 12 weeks, the children reported the event, answered questions about what usually happens in an examination, and rated their confidence in aspects of their reports. They remembered more typical than atypical present components, that is, those included in the examination, and, over time, falsely reported more typical than atypical actions. The children produced intrusions of expected-but-omitted medical features at the delay but with lower confidence ratings than they provided for correctly recalled items. Performance on a source monitoring task was associated with aspects of the children's confidence ratings for intrusions. The findings provide evidence that the relation between episodic and generic representations is dynamic and suggest that the capacity to differentiate between them contributes to the development of accurate eyewitness memory.     

Communicative Context Affects Use of Referential Prosody

The current study assessed the extent to which the use of referential prosody varies with communicative demand. Speaker–listener dyads completed a referential communication task during which speakers attempted to indicate one of two color swatches (one bright, one dark) to listeners. Speakers' bright sentences were reliably higher pitched than dark sentences for ambiguous (e.g., bright red versus dark red) but not unambiguous (e.g., bright red versus dark purple) trials, suggesting that speakers produced meaningful acoustic cues to brightness when the accompanying linguistic content was underspecified (e.g., “Can you get the red one?”). Listening partners reliably chose the correct corresponding swatch for ambiguous trials when lexical information was insufficient to identify the target, suggesting that listeners recruited prosody to resolve lexical ambiguity. Prosody can thus be conceptualized as a type of vocal gesture that can be recruited to resolve referential ambiguity when there is communicative demand to do so.     

A small-to-large unit progression in metaphonological awareness and reading?

The paper reports a series of studies of reading and metaphonological processing by children in their second year in primary school(aged 6 years). An earlier study had established that, in the first year of learning, performance was characterized by a small-unit approach in which graphemes and phonemes were emphasized. In the second year, reading became more sensitiveto the frequencies of rime structures in the lexicon. Capacity to generate word analogies for nonwords also showed increasing commitment to rime-based responses, and this trend was strongly linked to reading age. The present results suggest that a small-unit approach to reading is augmented by a large-unit approach as development proceeds. This trend was reflected in performance on a test of explicit phonological awareness. When asked to report the segment of sound shared by two spoken words, Primary 1 children were poor in reporting shared rimes but relatively adept in reporting shared phonemes. During Primary 2 there was an improvement in ability to report shared rimes, and this trend was also related to reading age. These results are discussed in relation to the influence of instruction and the nature of the orthography in determining the course of reading development.     

SIMILARITIES AND DIFFERENCES IN RELATIONAL BOUNDARIES AMONG HETEROSEXUALS, GAY MEN, AND LESBIANS

This study investigated the relative contributions of gender and sexual orientation as factors associated with the formation of boundaries in dyadic intimate relating in both same- and opposite-sex couples. The study examined a relational pattern previously not empirically investigated but widely accepted as an actuality unique to lesbians; specifically, that lesbians tend to remain connected to ex-serious-relationship partners after breakup. The study utilized a research design approach emphasizing the methodological utility and heuristic value of including sexual orientation as an independent variable in studies of gender dynamics. Two general classes of theoretical frameworks, those emphasizing gender role socialization influences and those emphasizing systems influences, were discussed in terms of their relative goodness of fit as conceptual bases for the data. Questionnaires were completed by 60 lesbians, 37 gay men, 45 heterosexual women, and 39 heterosexual men. Lesbians and gay men reported higher levels of connection to ex-serious-relationship partners than heterosexuals. The data reflect how inclusion of sexual orientation can broaden understandings of gender differentiated phenomena beyond more traditional gender-only based accounts.     

Stimulus Parameters Underlying Sound-Symbolic Mapping of Auditory Pseudowords to Visual Shapes

Sound symbolism refers to non-arbitrary mappings between the sounds of words and their meanings and is often studied by pairing auditory pseudowords such as “maluma” and “takete” with rounded and pointed visual shapes, respectively. However, it is unclear what auditory properties of pseudowords contribute to their perception as rounded or pointed. Here, we compared perceptual ratings of the roundedness/pointedness of large sets of pseudowords and shapes to their acoustic and visual properties using a novel application of representational similarity analysis (RSA). Representational dissimilarity matrices (RDMs) of the auditory and visual ratings of roundedness/pointedness were significantly correlated crossmodally. The auditory perceptual RDM correlated significantly with RDMs of spectral tilt, the temporal fast Fourier transform (FFT), and the speech envelope. Conventional correlational analyses showed that ratings of pseudowords transitioned from rounded to pointed as vocal roughness (as measured by the harmonics-to-noise ratio, pulse number, fraction of unvoiced frames, mean autocorrelation, shimmer, and jitter) increased. The visual perceptual RDM correlated significantly with RDMs of global indices of visual shape (the simple matching coefficient, image silhouette, image outlines, and Jaccard distance). Crossmodally, the RDMs of the auditory spectral parameters correlated weakly but significantly with those of the global indices of visual shape. Our work establishes the utility of RSA for analysis of large stimulus sets and offers novel insights into the stimulus parameters underlying sound symbolism, showing that sound-to-shape mapping is driven by acoustic properties of pseudowords and suggesting audiovisual cross-modal correspondence as a basis for language users' sensitivity to this type of sound symbolism.     

The Test–Retest Reliability and Predictive Validity of a Battery of Newly Developed Occupational Performance Assessments

The Canadian Occupational Performance Measure was used as a tool to compare goals for intervention identified by seven clients living in a long-term residential program and diagnosed with schizophrenia, with their goals as identified by the occupational therapist. In-depth interviews were conducted in conjunction with the use of the Canadian Occupational Performance Measure. Data analysis revealed an overarching theme that described the clients' concerns as, “I want to accomplish goals outside of the residence program.” During the analysis, however, the data revealed that the occupational therapist primarily focused her attention on goals to be achieved within the residence program, emphasizing programming and symptom management as each client's priorities for intervention, rather than community involvement. The findings reveal how data from the Canadian Occupational Performance Measure was used to reveal client/therapist disconnect in goal setting and the need to continue to examine client-centered practices in mental health settings.
