Stages-of-learning analysis of developmental interactions in memory,with illustrations from developmental interactions in picture-word effects

Although Age × Treatment interactions have been widely viewed as key results in theories of memory development, most examples of such results (e.g., Age × Treatment interactions in the effects of item concreteness, item elaboration, and organizational context) have been identified in list-learning experiments where children of different ages receive a small, fixed number of study-test cycles on the target list. A stages-of-learning analysis reveals that such designs confound a treatment's potential interactions with age and its potential interactions with stage of learning. The analysis also reveals specific situations in which such designs will produce converging, diverging, and crossover Age × Treatment interactions even though the treatment does not interact with age in any way. A series of experiments is reported in which a mathematical model that incorporates stages-of-learning distinctions is applied to the well-known interaction between age and item concreteness (pictures versus words) in cued recall. Although a diverging Age × Treatment interaction has been observed in previous research, it was found that there are at least four different interactions between the picture-word manipulation and age; (a) a diverging interaction at storage that operates throughout elementary school; (b) a diverging interaction localized within retrieval learning and operating during the first half of the elementary school; (c) a converging interaction localized within retrieval learning and operating during the second half of elementary school; and (d) a diverging interaction localized within retrieval performance and operating throughout elementary school.     

Beliefs About Psychological Services Among Guatemalan College Students

This mixed-methods study identified the help-seeking attitudes of Guatemalan college students. A random sample of 248 students across 2 universities responded to a cultural adaptation of the Beliefs About Psychological Services (BAPS; Ægisdóttir & Gerstein, 2009) survey. The directors of both universities and a subsample of participants were also interviewed. Quantitative findings demonstrated low levels of stigma and positive help-seeking attitudes among students. Qualitative findings indicated that psychological services were limited, financially out of reach, or failed to address students’ gender-specific concerns. Recommendations to address these challenges are presented. Este estudio de métodos mixtos identificó las actitudes de búsqueda de ayuda de estudiantes universitarios guatemaltecos. Una muestra aleatoria de 248 estudiantes de dos universidades respondió a una adaptación cultural de la encuesta Creencias sobre Servicios Psicológicos (BAPS, por sus siglas en inglés; Ægisdóttir & Gerstein, 2009). También se entrevistó a los directores de ambas universidades y a una submuestra de participantes. Los hallazgos cuantitativos demostraron bajos niveles de estigma y actitudes de búsqueda de ayuda positivas entre los estudiantes. Los hallazgos cualitativos indicaron que los servicios psicológicos eran limitados, no eran lo bastante asequibles o no abordaban las preocupaciones relativas al sexo de los estudiantes. Se presentan recomendaciones para abordar estos desafíos.     

Electrophysiological responses in mothers to their own and unfamiliar child's gaze information

An attachment bond between a mother and her child is one of the most intimate human relationships. It is important for a mother to be sensitive to her child's gaze direction because exchanging gaze information plays a vital role in their relationship. Furthermore, recent studies have revealed differential neural activation patterns in mothers when presented the faces of their own children or the unfamiliar child of other people. Based on these findings, in the present study, we investigated whether mothers show differential neural responses to gaze information of their own child compared to that of an unfamiliar child. To this end, event-related-potentials elicited by the faces of one's own or an unfamiliar child with straight or averted gaze directions were measured using an oddball-paradigm. The results showed that peak amplitudes of the N170 component were enlarged by viewing the straight gazes compared to the averted gazes of one's own child, but not of an unfamiliar child. When the gaze was directed straight, the P3 amplitude elicited by one's own child's face is smaller than that elicited by an unfamiliar child's face. P3s elicited in viewing one's own child's face with averted gaze and in viewing an unfamiliar child's face with straight gaze were positively correlated with state-anxiety. These results bolster the hypothesis that processing the gaze information of one's own child elicits differential neural activation compared to the gaze information of an other person's unfamiliar child at both perceptual and evaluative stages of face processing.     

From religious emotions to affects: historical and theoretical reflections on injury to feeling,self and religion

ABSTRACT

Images of angry Muslims have become a common sight in repeated controversies problematising the compatibility of Islam and freedom of speech. To explain such outrage, it is often put forward that Muslims reacted to the disrespect and violation of their ‘religious feelings’. In this paper, we challenge the trope of hurt religious feelings in the explanation of unrest. Referring to the writings of Schleiermacher, James and Taylor, the discussion traces how religion and feeling have become inextricably intertwined, located within the individual self and institutionalised as a dominant interpretation of religion. We introduce affect as a conceptual alternative to such understandings, which allows us to analyse the emphasis on Muslim emotionality as a relationship between Muslim and secular bodies, hence no longer reduced to the interiority of Muslim subjects. We will illustrate the potential of an affect-based approach discussing Muslim feelings’ vital role in the construction of European democracies.     

La habituación a corto plazo y las consecuencias del E habituador

Resumen

Con objeto de. comprobar si la habituación depende de las consecuencias del estimulo habituador, 24 ratas mistar fueron sometidas a habituación acústica de la respuesta de sobresalto. El grupo 1, en el que el sonido era segued de una consecuencia diferente en cada ensayo, no mostró prácticamente habituación, mientras que el grupo 2, en el que era seguido de una consecuencia fija (destello), mostró una habituación mayor incluso que en el grupo 3, de habituación normal (seguido de ausencia de consecuencias). Los datos parecen apoyar la hipótesis sostenida, a pesar de algunos problemas con el grupo 2.     

The Evolution of a Scientific Concept

A philosophically comprehended account is given of the genesis and evolution of the concept of protein. Characteristic of this development were not shifts in theory in response to new experimental data, but shifts in the range of questions that the available experimental resources were fit to cope with effectively. Apart from explanatory success with regard to its own range of questions, various other selecting factors acted on a conceptual variant, some stemming from a competing set of research questions, others from an altogether different field of inquiry, and still others from the external environment. These results are best explained on, hence support, an evolutionary model of the progress of experimental investigation, whose outlines are briefly discussed. This revised version was published online in August 2006 with corrections to the Cover Date.
