PSYCHOLOGICAL IMPACT OF MIGRATION ON LATINAS

This paper examines the psychological implications of the migratory process on Latin American women in the United States, addressing is-sues of gender roles, acculturation, language, loss, and grief that are frequently presented by immigrant Latinas in psychotherapy. The paper interprets these issues as reflective of the stresses created by the migratory process rather than as issues of individual psychopathology, and suggests ways to respond to them through psychotherapy.     

A dynamic phonological model derived from the intonational analysis of a jargon aphasic patient

This study is a detailed phonological and intonational analysis of one subject's jargon productions. The cohesiveness and complexity of the intonation patterns and appropriateness of the gestures lead to the hypothesis that the jargon productions are due to phonological problems as opposed to semantic or syntactic problems. A psycholinguistic model containing a dynamic phonological component is hypothesized to account for this subject's jargon.     

Autonomy and interdependence: beliefs of Brazilian mothers from state capitals and small towns

This study aimed to investigate characteristics of Brazilian mothers' beliefs system, in the dimensions of autonomy and interdependence. A group of 600 women, half from state capitals and half from small towns, participated in the study. They were individually interviewed with Scales of Allocentrism, Beliefs about Parental Practices and Socialization Goals. Paired and Independent samples t tests and Multivariate GLM were performed. The results indicate that although mothers from both contexts value autonomy, mothers inhabiting small towns considered the relational dimension as the most important; whereas mothers inhabiting capitals valued equally both dimensions, either in their beliefs about practices or in the socialization goals for their children. Mothers from small towns have a higher mean score for allocentrism than mothers living in capitals. Thus, place of residence proved to be a relevant variable in the modulation of maternal beliefs. Educational level was not a significant factor in the variables considered and with this group of mothers. The study results are discussed in terms of their contribution to the understanding of the complex relationship between dimensions of autonomy and interdependence in mothers' beliefs system.     

A microswitch program to foster simple foot and leg movements in adult wheelchair users with multiple disabilities

This study assessed a microswitch program to foster simple foot and leg movements in 2 adult wheelchair users with multiple disabilities. The participants' mood (indices of happiness) was recorded throughout the study. Data showed that participants rapidly increased the target foot and leg movements and maintained those movements during the course of the study, which lasted about 4.5 months. With regard to indices of happiness, 1 participant showed a fairly modest increase during the intervention while the other participant showed a substantial increase. Implications of the findings are discussed.     

Independent manipulation of emotion in an emotional stroop task using classical conditioning

The effects of emotional connotation on emotional Stroop interference in anxiety were examined. First, a classical conditioning paradigm was used in which neutral words and nonwords were paired with either negative or neutral pictures. These conditioned stimuli were then presented in an emotional Stroop paradigm. Finally, participants rated each word and nonword for emotional connotation. The high-anxious group demonstrated significant interference for the nonwords that had been negatively conditioned, and these effects did not dissipate over time. The affective rating data supported the view that nonwords, but not the words had been successfully conditioned in the high-anxious group. This experiment provides evidence for the importance of emotional connotation rather than confounded semantic factors in the emotional Stroop effect.     

Enabling persons with multiple disabilities to choose among environmental stimuli and request stimulus repetitions through microswitch and computer technology

This study assessed microswitch and computer technology to enable two participants with multiple disabilities, 32 and 19 years of age, to choose among environmental stimuli and request their repetition whenever they so desired. Within each session, 18 stimuli (12 preferred and 6 nonpreferred) were available. For each stimulus, a computer system provided a sample of 3 sec. duration. During the intervention, participants' vocal responding in relation to a stimulus sample activated a microswitch and a computer system turned on that stimulus for 15-30 sec. When participants did not vocally respond, the computer system paused briefly and then presented the next scheduled stimulus sample. When participants vocally responded at the end of a stimulus presentation, the stimulus was repeated. Intervention data showed that the participants learned to choose preferred stimuli and bypass nonpreferred ones as well as to request repetitions of the preferred stimuli. This performance was maintained at a 1-mo. postintervention check and transferred to sets of stimuli not used in the intervention. The implications of these results were discussed.     

Promoting fluency of performance during morning dressing by two persons with multiple disabilities

This study investigated the possibility of promoting fluency of performance, i.e., a performance independent of caregiver's guidance and without serious interruptions, during morning dressing in two adults with multiple disabilities. The intervention program relied on the use of assistive technology including optic and pressure sensors to monitor the participants' task responding and tape players to present preferred stimuli in relation to such responding, as well as messages of encouragement. Analysis showed that the intervention program was effective with both participants. In fact, they became capable of performing the dressing sequence with only occasional guidance from research assistants, and the time they required for dressing dropped significantly from baseline levels. Implications of the results are discussed.     

Contextual guidance of eye movements and attention in real-world scenes: the role of global features in object search

Many experiments have shown that the human visual system makes extensive use of contextual information for facilitating object search in natural scenes. However, the question of how to formally model contextual influences is still open. On the basis of a Bayesian framework, the authors present an original approach of attentional guidance by global scene context. The model comprises 2 parallel pathways; one pathway computes local features (saliency) and the other computes global (scene-centered) features. The contextual guidance model of attention combines bottom-up saliency, scene context, and top-down mechanisms at an early stage of visual processing and predicts the image regions likely to be fixated by human observers performing natural search tasks in real-world scenes.
