Escaping from Rama: Portraits of Indian women

This study examines visual, post-colonial portraits of the Indian women of the Sanskrit epics, in order to show the sociocultural, historical-ideological roots of this aesthetic. After independence, Hindu movements found in the epics a female archetype, who stands for the Hindu community. Post-colonial visual representations maintained this idealistic characterisation within a binary system, according to which women can be angelic guarantors of the social order or devilish, sexually uncontrolled creatures. This ambiguity derives from the double nature of the female principle of the world, shakti, and the visual storytelling tradition or chitrakatha. Using the same Indian storytelling tradition, female points of view have begun to criticise this nationalistic, ‘male gaze’. In the graphic novel Sita's Ramayana, Rama and male activities, particularly war, are secularised and criticised as selfish by female characters, foremost of whom is Sita, a model of the devoted and pure bride or pativrata.     

Spatial attention and feature-based attention are differentially sensitive to individual working memory capacity and perceptual load

ABSTRACT

A central and long-standing topic of interest to both psychologists and neuroscientists has been the capacity limited nature of perception, cognition and action. Most often, attention is the term invoked to label the mechanism by which a limited cognitive system can prioritize and select a subset of task-relevant sensory inputs and actions amongst a seemingly unbounded set of possible representations and behaviour. This selective mechanism is often modelled as a unitary and domain-general capacity-limited resource that is dynamically shifted to meet the processing demands invoked by the context. The present work offers a test of the unitary attention hypothesis using a variant of a classic validity manipulation [(Posner, M. I. (1980). Orienting of attention. Quarterly Journal of Experimental Psychology, 32, 3–25)] and the inferential logic of Sternberg (2001. Separate modifiability, mental modules, and the use of pure and composite measures to reveal them. Acta Psychologica, 106, 147–246). The results stand as evidence for at least two modular visual attention systems split according to a spatial and feature-based reference.     

Eye movement indices of memory reveal re-processing of visual information: Evidence from Chinese characters

ABSTRACT

This study examined the nature of the memory effect revealed in eye movements. Chinese characters were processed visually, phonologically or semantically during the study phase. The proportion of viewing time during the subsequent recognition test was compared between characters associated with different types of encoding. To eliminate the influence of response selection on eye movements, participants were asked to select the unstudied character and make the selection after the viewing period ended. Results showed that the proportion of viewing time in the recognition test was larger for visually encoded characters than it was for semantically (Experiment 1) and phonologically encoded (Experiment 3) characters, even after the participants had presumably made the decision. Moreover, there was no significant difference in the proportion of viewing time between phonologically and semantically encoded characters (Experiment 2). These findings suggest that the viewing time change in eye movements during the recognition test is an obligatory consequence of re-processing the visual information encoded during the study phase.     

Alzheimer's Disease Does Not Selectively Impair Decisions About Word Meaning

Patients with probable Alzheimer's disease (AD) and normal young and older participants were asked to make decisions about the orthography, phonology and semantics of visually presented stimulus words. Whereas AD patients were slower than normals in making decisions, there was no evidence that they were any more impaired in making one type of decision than another. Specifically, they did not show a disproportionate slowing for decisions requiring access to word meaning. These results are not consistent with a degradation of semantic knowledge in AD, but rather suggest the presence of a relatively generalized slowing of information processing.     

The Mmogo-Method™: Discovering Symbolic Community Interactions

In this article the development and implementation of the Mmogo-Method? is discussed as a culture-sensitive data collection method. The Mmogo-Method? provides opportunities for social researchers to gain a deeper understanding of the cultural symbolism in which social life is embedded and that informs experiences, perceptions and behaviour. In this method, people create their own data by making visual presentations that reflect contextually grounded symbolic meanings. Theoretical underpinnings of social constructionism, symbolic interactionism and community psychology are discussed and applied as the rationale for the development and implementation of the Mmogo-Method?. Examples of research using the Mmogo-Method? are provided to illustrate its value and various different application possibilities. The Mmogo-Method? attempts to produce community-based knowledge that is gathered and disseminated in a coherent way; thereby contributing to the possibility that indigenous knowledge may form part of national and international discussions.     

Indirect interception actions by blind and sighted perceivers: The role of modality and tau

Vernat, J.‐P. & Gordon, M.S. (2011). Indirect interception actions by blind and sighted perceivers: The role of modality and tau. Scandinavian Journal of Psychology 52, 83–92. Acoustic and visual interceptive actions were tested in this research by comparing the performance of blind, blind‐folded, and sighted individuals. An indirect interception method was employed in which the participant had to roll an intercepting ball towards a moving target on a perpendicular track. The interception task used conditions that varied the speed, rolling distance, and target size/intensity. While performance was highly consistent and accurate for visual participants in this research, the blind and blind‐folded participants demonstrated much more performance variability in response to changes in speed and distance. Manipulation of target size and intensity did not affect judgments, however performance tended to be more accurate at shorter distances and with faster target speeds. Results from this research are discussed in terms of their implications for tau in acoustic interception, and the use of spatial and temporal cues for guiding interceptive actions.     

Seeing bodies in pain: from Hippocrates to Freud

The study of pain has a history as long as that of Western medicine. In the 20th and 21st centuries much has been made about the epistemological problem of seeing somatic as well as psychic pain in the clinical setting. The two schools seem to be those which rely on self-reporting and those that rely on the interpretation of visual materials (expression or brain scans) by trained specialists. That this problem was central to the 19th century study of pain is clear as these origins (especially Darwin) are often cited in today's literature as 'proof' of their validity. That the problem was also central to one of the early 20th century thinkers most indebted to Darwin, Sigmund Freud, is less well known and how he resolved this paradox of self-reporting versus seeing seems to have been overlooked.     

Attentional sensitization of unconscious visual processing: Top-down influences on masked priming

Classical theories of automaticity assume that automatic processes elicited by unconscious stimuli are autonomous and independent of higher-level cognitive influences. In contrast to these classical conceptions, we argue that automatic processing depends on attentional amplification of task-congruent processing pathways and propose an attentional sensitization model of unconscious visual processing: According to this model, unconscious visual processing is automatic in the sense that it is initiated without deliberate intention. However, unconscious visual processing is susceptible to attentional top-down control and is only elicited if the cognitive system is configured accordingly. In this article, we describe our attentional sensitization model and review recent evidence demonstrating attentional influences on subliminal priming, a prototypical example of an automatic process. We show that subliminal priming (a) depends on attentional resources, (b) is susceptible to stimulus expectations, (c) is influenced by action intentions, and (d) is modulated by task sets. These data suggest that attention enhances or attenuates unconscious visual processes in congruency with attentional task representations similar to conscious perception. We argue that seemingly paradoxical, hitherto unexplained findings regarding the automaticity of the underlying processes in many cognitive domains can be easily accommodated by our attentional sensitization model. We conclude this review with a discussion of future research questions regar-ding the nature of attentional control of unconscious visual processing.
