Relationships among Facial,Prosodic, and Lexical Channels of Emotional Perceptual Processing

This study was designed to address the issue of whether there is a general processor for the perception of emotion or whether there are separate processors. We examined the relationships among three channels of emotional communication in 100 healthy right-handed adult males and females. The channels were facial, prosodic/intonational, and lexical/verbal; both identification and discrimination tasks of emotional perception were utilised. Statistical analyses controlled for nonemotional perceptual factors and subject characteristics (i.e. demographic and general cognitive). For identification, multiple significant correlations were found among the channels. For discrimination, fewer correlations were significant. Overall, these results provide support for the notion of a general processor for emotional perceptual identification in normal adult subjects.     

Influence of aging on recovery from aphasia in polyglots

We analyzed patterns of recovery, according to the rules of Pitres [1895, Revue de Medecine (Paris), 15, 873–899] and Ribot (1881, Les Maladies de la Memoire, Paris: Libraire Germer Baillere et Cie, pp. 146–147), in polyglot aphasics divided into subgroups by age. The rule of Ribot did not apply predictably for any age group. Pitres' rule clearly applied, but only for the nonelderly groups. Aging and its concomitant deterioration of recent memory seem to influence patterns of recovery from aphasia in polyglots.     

Effect of socioeconomic status on aphasia severity and recovery

Low levels of educational attainment and low socioeconomic status have been significantly linked to poor health and increased incidence of disease, including Alzheimer's disease and diseases of the cardiovascular, pulmonary, renal, and gastrointestinal systems. Our goal in the present study was to determine the degree to which educational level and socioeconomic status influence initial severity of aphasia and subsequent recovery. We evaluated the records of 39 persons with aphasia twice: at about 4 months and 103 months postonset. We found early severity of aphasia to be significantly greater for subjects in the lower educational and occupational groups. However, rate of recovery (the slope of the recovery curve) was the same regardless of educational or occupational status.     

Levels of Abstractness in Semantic Noun and Verb Processing: The Role of Sensory-Perceptual and Sensory-Motor Information

Journal of Psycholinguistic Research - Effects of concreteness and grammatical class on lexical-semantic processing are well-documented, but the role of sensory-perceptual and sensory-motor...
