Intensive training of phonological skills in progressive aphasia: a model of brain plasticity in neurodegenerative disease

Three patients with a typical syndrome of nonfluent primary progressive aphasia (Mesulam's syndrome) were trained daily with a remediation protocol including auditory exercises specifically designed to involve several aspects of phonological processing, a domain known to be specifically affected in the condition. The speech content of the exercises was based on the temporal theory of phonological processes according to which increasing the duration of formant transition should facilitate phoneme discrimination and phoneomic awareness. Significantly improved performance on the trained tasks was demonstrated in the three patients. Improvement further generalized to other tasks such as nonword repetition and reading. We conclude that such results (1) argue for using intensive focused therapy of language impairment in neurodegenerative disorders, (2) may constitute a good model of brain plasticity in neurodegenerative disorders in general, and (3) support theories of phonological processing emphasizing temporal features of the auditory signal.     

Quality of life of patients with amyotrophic lateral sclerosis

The aim of this study is to evaluate the correlation between different measures of quality of life (QoL), functional status and mood status in patients with amyotrophic lateral sclerosis (ALS). A sample of 40 patients with ALS was recruited and scales for the evaluation of health-related QoL (SF36), patient-centered QoL (SEIQoL), functional status (ALSFRS) and depression (ZDS) have been administered to them. All the correlations (Pearson's r) between the scores have been considered and the t-test was performed in order to compare male with female patients. No correlation emerged between the different measures of QoL and functional status, apart from the scores of the Physical Functioning subscale of the SF36 which resulted positively correlated (p?相似文献   

The contribution of visual processing to academic achievement in adolescents born extremely preterm or extremely low birth weight

Children born extremely preterm (EP, <28 weeks) and/or extremely low birth weight (ELBW, <1000 g) have more academic deficiencies than their term-born peers, which may be due to problems with visual processing. The aim of this study is to determine (1) if visual processing is related to poor academic outcomes in EP/ELBW adolescents, and (2) how much of the variance in academic achievement in EP/ELBW adolescents is explained by visual processing ability after controlling for perinatal risk factors and other known contributors to academic performance, particularly attention and working memory. A geographically determined cohort of 228 surviving EP/ELBW adolescents (mean age 17 years) was studied. The relationships between measures of visual processing (visual acuity, binocular stereopsis, eye convergence, and visual perception) and academic achievement were explored within the EP/ELBW group. Analyses were repeated controlling for perinatal and social risk, and measures of attention and working memory. It was found that visual acuity, convergence and visual perception are related to scores for academic achievement on univariable regression analyses. After controlling for potential confounds (perinatal and social risk, working memory and attention), visual acuity, convergence and visual perception remained associated with reading and math computation, but only convergence and visual perception are related to spelling. The additional variance explained by visual processing is up to 6.6% for reading, 2.7% for spelling, and 2.2% for math computation. None of the visual processing variables or visual motor integration are associated with handwriting on multivariable analysis. Working memory is generally a stronger predictor of reading, spelling, and math computation than visual processing. It was concluded that visual processing difficulties are significantly related to academic outcomes in EP/ELBW adolescents; therefore, specific attention should be paid to academic remediation strategies incorporating the management of working memory and visual processing in EP/ELBW children.     

Late Adoptions: Attachment Security and Emotional Availability in Mother–Child and Father–Child Dyads

A growing body of research suggests that a history of neglect, abuse and institutionalization can negatively affect late-adopted children’s attachment representations, and that adoptive parents can play a key role in enabling adopted children to earn secure attachments. Still, only a few studies have explored the quality of caregiver–child interaction in adoptive families. The present study aimed at verifying both the concordance of attachment in adoptive dyads (mother–children and father–children) and the relationship between attachment representations and parent–child interaction. The research involved 20 adoptive families in which the child’s arrival had occurred between 12 to 36 months before the assessment, and where children were aged between 4.5 and 8.5 years. Attachment was assessed through the Adult Attachment Interview for parents and through the Manchester Child Attachment Story Task for children. The emotional quality of parent–child interaction was assessed trough the Emotional Availability Scales. Our results pointed out the presence of a relation between attachment representations of late-adopted children and their adoptive mothers (75%, K?=?0.50, p?=?.025). In addition, we found that both insecure children and mothers showed lower levels of EA than secure ones. Some explanations are presented about why, in the early post-adoption period, child attachment patterns and dyadic emotional availability seem to be arranged on different frameworks for the two parental figures.     

Attentional requirements is visual detection and identification: evidence from the attentional blink

Perception of the 2nd of 2 targets (T1 and T2) is impaired if the lag between them is short (0-500 ms). The authors used this attentional blink (AB) to index attentional requirements in detection and identification tasks, with or without backward masking of T2, in 2 stimulus domains (line orientation, coherent motion). With masking, the AB occurred because T2 was masked during the attentional dwell time created by T1 processing (Experiments 1, 2, and 3). Without masking, an AB occurred only in identification because during the attentional dwell time, T2 decayed to a level that could support simple detection but not complex identification. However, an AB occurred also in detection if T2 was sufficiently degraded (Experiment 4). The authors drew 2 major conclusions: (a) Attention is required in both identification and detection, and (b) 2 factors contribute to the AB, masking of T2 while attention is focused on T1 and decay of the T2 trace while unattended.     

The interhemispheric transcallosal-transversal approach to the lesions of the anterior and middle third ventricle: surgical validity and neuropsychological evaluation of the outcome

Based on the observation of the course of callosal fibres and of their artero-venous support as appearing in a microanatomic study, the Authors propose a variant of standard callosotomy procedure by the introduction of the transverse section of callosal fibres. This technique would allow the surgeon to spare a larger number of callosal fibres by the combined effect of a lower direct mechanical traction on fibres and a lower impact on artero-venous microcircle. The neuropsychological outcome of the patients who underwent this kind of procedure was evaluated. Fourteen patients affected by occupying-space lesions involving the anterior and middle third ventricle were included in the study. Ten patients underwent transverse callosotomy, four subjects received standard sagittal callosotomy. A control group was also included in the study. All patients underwent a pre-operative and six months post-operative neuropsychological evaluation focused on performance at cognitive and attentional tasks. No disturbances in executive function were observed in either group. Patients receiving transverse callosotomy performed as well as control group subjects in attentive tasks, which is not the case of patients undergoing sagittal callosotomy who show a marked deficit in selective attention for left side visual field. The observed more favourable neuropsychological outcome supports transverse callosotomy as a valid alternative method to standard longitudinal callosotomy in third ventricle surgery.     

Human affection exchange: VI. Further tests of reproductive probability as a predictor of men's affection with their adult sons

The authors examined the communication of affection in men's relationships with their fathers. Drawing from Affection Exchange Theory, the authors advanced four predictions: (a) heterosexual men receive more affection from their own fathers than do homosexual or bisexual men, (b) fathers communicate affection to their sons more through supportive activities than through direct verbal statements or nonverbal gestures, (c) affectionate communication between fathers and sons is linearly related to closeness and interpersonal involvement between them, and (d) fathers' awareness of their sons' sexual orientation is associated with the amount of affection that the fathers communicate to them. Participants were 170 adult men who completed questionnaires regarding affectionate communication in their relationships with their fathers. Half of the men were self-identified as exclusively heterosexual, and the other half were self-identified as exclusively homosexual or bisexual. The results supported all predictions substantially.     

Bolstering implementation plans for the long haul: the benefits of simultaneously boosting self-concordance or self-efficacy

Recent studies suggest that implementation planning exercises may not be as helpful for long-term, self-initiated goals as for short-term, assigned goals. Two studies used the personal goal paradigm to explore the impact of implementation plans on goal progress over time. Study 1 examined whether administering implementation plans in an autonomy supportive manner would facilitate goal progress relative to a neutral, control condition and a condition in which implementation plans were administered in a controlling manner. Study 2 examined whether combining implementation plans with a self-efficacy boosting exercise would facilitate goal progress relative to a neutral, control condition and a typical implementation condition. The results showed that implementation plans alone did not result in greater goal progress than a neutral condition but that the combination of implementation plans with either autonomy support or self-efficacy boosting resulted in significantly greater goal progress.     

Focal distraction: spatial shifts of attentional focus are not required for contingent capture

Contingent capture occurs when distractors that share the target's defining attribute capture attention and slow down target identification. This slowdown has been attributed to an involuntary attentional shift to the location of a pertinent distractor. The present study examined an additional source of delay: the time spent in processing pertinent distractors. In 7 experiments, distractors were presented at fixation, and targets were presented either at fixation or peripherally. Contingent capture invariably occurred when a salient distractor was presented within about 600 ms before the target, even when spatial shifts in attentional focus were ruled out. A 2-stage model is proposed in which stimuli must pass an input filter tuned to the target's defining attribute before gaining access to a high-level stage that is unavailable while a distractor is being processed.
