Analysis of voice impairment in aphasia after stroke-underlying neuroanatomical substrates

Phonation is a fundamental feature of human communication. Control of phonation in the context of speech-language disturbances has traditionally been considered a characteristic of lesions to subcortical structures and pathways. Evidence suggests however, that cortical lesions may also implicate phonation. We carried out acoustic and perceptual analyses of the phonation of /a/ in 60 males with aphasia (20 Wernicke's, 20 Broca's, 20 subcortical aphasia) and 20 males matched in age with no neurological or speech-language disturbances. All groups with aphasia were significantly more impaired on the majority of acoustic and perceptual measures as compared with the control speakers. Within the subjects with aphasia, subjects with subcortical aphasia were more impaired on most measures compared to subjects with Broca's aphasia, and they, in turn, more impaired than those with Wernicke's aphasia. Lesions in regions involved in sound production-perception result in dysfunction of the entire neurocognitive system of articulation-phonological language processing.     

Cross-linguistic parallels in processing derivational morphology: Evidence from Polish

Neuroimaging evidence in English suggests that the neurocognitive processing of derivationally complex words primarily reflects their properties as whole forms. The current experiment provides a cross-linguistic examination of these proposals by investigating the processing of derivationally complex words in the rich morphological system of Polish. Within the framework of a dual language system approach, we asked whether there is evidence for decompositional processing of derivationally complex Polish stems – reflected in the activation of a linguistically specific decompositional system in the left hemisphere – or for increased competition between the derived stem and its embedded base stem in the bilateral system. The results showed activation in the bilateral system and no evidence for selective engagement of the left hemisphere decompositional system. This provides a cross-linguistic validation for the hypothesis that the neurocognitive processing of derived stems primarily reflects their properties as stored forms.     

Gender differences in the construction and experience of cancer care: The consequences of the gendered positioning of carers

The experience and construction of caring in 50 informal cancer carers, 35 women and 15 men, was examined using a critical realist approach and a mixed method design. Women reported higher rates of depression, anxiety, unmet needs and burden of care than men. No gender differences were found in time spent care-giving, suggesting that gendered roles are implicated in distress and coping. Semi-structured interviews with 13 carers were used to identify gender differences in caring, analysed using positioning theory. Women described being positioned as all encompassing expert carers, expected to be competent at decision-making, a range of physical caring tasks, and provision of emotional support for the person with cancer. The consequences of this positioning were over-responsibility and self-sacrifice, physical costs and overwhelming emotions, which were self-silenced. In contrast, men carers positioned caring as a competency task which they had mastered, and which provided them with satisfaction, with the emotions of the person with cancer, or their own emotions, being negative aspects of caring. It is concluded that cancer caring is tied to gendered constructions and expectations, with considerable implications for psychological well-being and coping, and for carer support services, which need to take gender issues on board.     

Peas in a pod: biases in the measurement of sibling temperament?

The authors of the present study addressed the measurement of temperament by examining the convergence between observational and questionnaire measures and the occurrence of contrast effects in parental ratings of non-twin siblings on the Children's Behavior Questionnaire. Fathers', mothers', and observers' ratings of 94 early-school-age sibling pairs were obtained longitudinally such that siblings were rated at the same time and when they were the same ages. Convergence between laboratory observations and questionnaires was generally modest to moderate for shyness and activity level; low to modest for positive emotionality, fear, and interest; and low for anger and sadness. We found some evidence of contrast effects for activity level and fathers' ratings of shyness and of assimilation effects for anger and sadness. The results highlight the complexity of measuring temperament and suggest that rater biases should be evaluated according to the measurement instrument used.     

A cognitive map of Slovenia: Perceptions of the regions

Cognitive maps present an important theoretical concept and methodological tool for the acquirement of insight into the mental image of the environment. Part of the study, conducted in 1999–2000 on a representative sample of the inhabitants of Slovenia (N = 1291), is presented in this paper, namely the part devoted to the perception of regions. Participants were questioned about different aspects of their image of Slovenia, including their preferences for residence in different parts of Slovenia, partition of the country into regions, travelling patterns, environmental problems and solutions, possibilities of development, etc. Cognitive maps appeared as highly selective, with certain general similarities, but also with individual idiosyncrasies, depending on the place of living and other demographic characteristics. Though respondents were not highly devoted to the formation of regions, a rather clear mental image of them appeared. Main findings are discussed and applicability of the cognitive map for planning purposes are substantiated.     

Multimethod longitudinal assessment of temperament in early childhood

The present study examined consistency of temperament across situations and time in early childhood. On two occasions, 7 months apart, we observed the responses of 94 four-year-olds to multiple standard laboratory procedures eliciting exuberance, fear, anger, sadness, or interest. In addition, fathers' and mothers' reports on children's temperament were obtained. Observed temperament showed substantial context specificity, varying across situations within dimensions. Structural equation models revealed separate observation and parental perception factors and factorial invariance and high stability for most dimensions. Stability coefficients based on correlations varied according to level of aggregation. Measurement convergence was generally moderate and was lowest for negative emotionality. Implications for the assessment of temperament are discussed in relation to differences in consistency across dimensions and convergence between measures.     

Bidirectional Associations Between Coparenting Relations and Family Member Anxiety: A Review and Conceptual Model

Research into anxiety has largely ignored the dynamics of family systems in anxiety development. Coparenting refers to the quality of coordination between individuals responsible for the upbringing of children and links different subsystems within the family, such as the child, the marital relationship, and the parents. This review discusses the potential mechanisms and empirical findings regarding the bidirectional relations of parent and child anxiety with coparenting. The majority of studies point to bidirectional associations between greater coparenting difficulties and higher levels of anxiety. For example, the few available studies suggest that paternal and perhaps maternal anxiety is linked to lower coparental support. Also, research supports the existence of inverse links between coparenting quality and child anxiety. A child’s reactive temperament appears to have adverse effects on particularly coparenting of fathers. A conceptual model is proposed that integrates the role of parental and child anxiety, parenting, and coparenting, to guide future research and the development of clinical interventions. Future research should distinguish between fathers’ and mothers’ coparenting behaviors, include parental anxiety, and investigate the coparental relationship longitudinally. Clinicians should be aware of the reciprocal relations between child anxiety and coparenting quality, and families presenting for treatment who report child (or parent) anxiety should be assessed for difficulties in coparenting. Clinical approaches to bolster coparenting quality are called for.
