When meaning matters,look but don’t touch: The effects of posture on reading

Much of the reading that we do occurs near our hands. Previous research has revealed that spatial processing is enhanced near the hands, potentially benefiting several processes involved in reading; however, it is unknown whether semantic processing—another critical aspect of reading—is affected near the hands. While holding their hands either near to or far from a visual display, our subjects performed two tasks that drew on semantic processing: evaluation of the sensibleness of sentences, and the Stroop color-word interference task. We found evidence for impoverished semantic processing near the hands in both tasks. These results suggest a trade-off between spatial processing and semantic processing for the visual space around the hands. Readers are encouraged to be aware of this trade-off when choosing how to read a text, since both kinds of processing can be beneficial for reading.     

Entrevista con Isidoro Gormezano

RESUMEN

La investigación básica en aprendizaje sigue teniendo un papel central en la psicología contemporánea (aunque no prácticamente único, como llegó a ser en algún momento de la historia de nuestra ciencia). Dentro de este campo ha sido importante la investigación sobre mecanismos de condicionamiento realizada por Isodoro Gormezano, director de los laboratorios Spence, en Iowa. En esta entrevista realiza una breve reflexión sobre los desarrollos actuales de la psicología del aprendizaje y refiere algunos aspectos de su historia. Algunas de las posiciones mantenidas por Gormezano están fuera de la línea de opinión dominante en muchos sectores de la psicología contemporánea, por lo que pueden alentar un pensamiento crítico muy necesario para reflexionar sobre la psicología actual.     

La tarea de seguimiento en el estudio de la atención selectiva

Resumen

La utilización de la tarea de seguimiento en el estudio de la atención selectiva, ha dado lugar a un gran número de resultados confusos y contradictorios que han influido en el mantenimiento de la controversia sobre el problema de la selectividad.

El objetivo del presente artículo fue analizar algunos factores responsables de esta discrepancia experimental: 1. Problemas metodológicos asociados con los estudios de seguimiento.

2. Variables relacionadas con la tarea de seguimiento cuya influencia no ha sido tomada en cuenta en la literatura.

3. Concepciones teóricas extremas sobre la atención selectiva.

El análisis realizado sugiere un replanteamiento de los problemas de selectividad y capacidad, donde se cuestione la dicotomia selección anterior/posterior y en su lugar se asuman concepciones más flexibles del proceso atencional.     

Comunicación simultánea: un modelo para enfrentar los déficit lingüísticos del niño autista

Resumen

El empleo de procedimientos de comunicación simultánea, en el tratamiento de los niños autistas, es una de las vías más prometedoras para incrementar la competencia comunicativa de estos niños. En este articulo se revisan los resultados del tratamiento de dos niños autistas con métodos de comunicación simultánea y las implicaciones de este método para el tratamiento de los niños autistas.     

死亡凸显对自我姓名注意瞬脱对抗效应的影响

已有研究表明死亡凸显会抑制自我面孔和自我参照记忆加工的自我优势,可是死亡凸显对自我姓名的影响尚不明确,本研究采用事件相关电位技术,探索死亡凸显对自我姓名注意瞬脱对抗效应及其大脑神经活动的影响。58名被试在经历不同的启动任务后,完成自我姓名、朋友姓名和名人姓名的注意瞬脱任务。行为结果发现自我姓名识别正确率显著高于朋友姓名和名人姓名,表现出稳定的自我姓名加工的注意瞬脱对抗效应;电生理数据发现死亡启动后自我姓名诱发的P300波幅显著低于消极启动组和中性启动组,而朋友姓名和名人姓名并不受启动的影响。本研究结果与以往研究结果共同表明死亡想法凸显会使个体将抑制自我加工（自我姓名、自我面孔和自我参照记忆）作为应对远端死亡焦虑的一种手段。     

Influence of articulation rate on two memory tasks in young and older adults

This study investigated the relation between phonological loop functioning and age. Phonological loop is a time-based subsystem of the Working Memory Model of Baddeley and Wilson, which uses rehearsal of information as an active process to avoid phonological decay. Performance differences were examined between young and older adults in two speech-based memory tasks, such as the immediate serial recall of words and the Digit Ordering Task. Analysis showed that performance on both tasks was lower for the older group. Articulation rate was also measured to test the hypothesis that the impairment of some cognitive functions in adults can be associated to their slowness or the greater time needed by older adults for the rehearsal process. A significant negative correlation was found for articulation rate with age. When the effect of articulation rate on Serial Recall and Digit Ordering Tasks was partialled out, the difference between the two groups was eliminated.     

Discrimination against facially stigmatized applicants in interviews: an eye-tracking and face-to-face investigation

Drawing from theory and research on perceived stigma (Pryor, Reeder, Yeadon, & Hesson-McInnis, 2004), attentional processes (Rinck & Becker, 2006), working memory (Baddeley & Hitch, 1974), and regulatory resources (Muraven & Baumeister, 2000), the authors examined discrimination against facially stigmatized applicants and the processes involved. In Study 1, 171 participants viewed a computer-mediated interview of an applicant who was facially stigmatized or not and who either did or did not acknowledge the stigma. The authors recorded participants' (a) time spent looking at the stigma (using eye tracker technology), (b) ratings of the applicant, (c) memory recall about the applicant, and (d) self-regulatory depletion. Results revealed that the participants with facially stigmatized applicants attended more to the cheek (i.e., where the stigma was placed), which led participants to recall fewer interview facts, which in turn led to lower applicant ratings. In addition, the participants with the stigmatized (vs. nonstigmatized) applicant depleted more regulatory resources. In Study 2, 38 managers conducted face-to-face interviews with either a facially stigmatized or nonstigmatized applicant, and then rated the applicant. Results revealed that managers who interviewed a facially stigmatized applicant (vs. a nonstigmatized applicant) rated the applicant lower, recalled less information about the interview, and depleted more self-regulatory resources.     

精神分裂症神经影像学研究述评

全世界约有1%的人患有精神分裂症,对患者及其家人造成了严重负担.由于此病影响因素很多,精神分裂症研究进展所取得的进步有限.精神分裂症产生的物质基础在脑,神经影像技术的进步为我们直接研究此病活体脑部结构及功能提供了良好的工具.本文主要从四个方面介绍了神经影像学在精神分裂症的研究及所贯彻的哲学思想.     

Preserved learning about allocentric cues but impaired flexible memory expression in rats with hippocampal lesions

Several studies have shown that slight modifications in the standard reference spatial memory procedure normally used for allocentric learning in the Morris water maze and the radial maze, can overcome the classic deficit in allocentric navigation typically observed in rats with hippocampal damage. In these special paradigms, however, there is only intramaze manipulation of a salient stimulus. The present study was designed to investigate whether extramaze manipulations produce a similar outcome. With this aim a four-arm plus-shaped maze and a reference spatial memory paradigm were used, in which the goal arm was marked in two ways: by a prominent extramaze cue (intermittent light), which maintained a constant relation with the goal, and by the extramaze constellation of stimuli around the maze. Experiment 1 showed that, unlike the standard version of the task, using this special training procedure hippocampally-damaged rats could learn a place response as quickly as control animals; importantly, one day after reaching criterion, lesioned and control subjects performed the task perfectly during a transfer test in which the salient extramaze stimulus used during the acquisition was removed. However, although acquisition deficit was overcomed in these lesioned animals, a profound deficit in retention was detected 15 days later. Experiment 2 suggests that although under our special paradigm hippocampal rats can learn a place response, spatial memory only can be expressed when the requisites of behavioral flexibility are minimal. These findings suggest that, under certain circumstances, extrahippocampal structures are sufficient for building a coherent allocentric representation of space; however, flexible memory expression is dependent, fundamentally, on hippocampal functioning.
