The role of syllabic and orthographic properties of letter cues in solving word fragments

The present research examined the role of phonological and orthographic properties of cues in mediating the retrieval of words from the mental lexicon. The task required subjects to resolve fragmented words when provided with semantically related cues (e.g., spiteful:---DIC----). Phonological properties of the letter cues were manipulated such that the letters either corresponded to the syllables (e.g., DIC in vindictive) or nonsyllables (NDI) in the word. Orthographic properties of the letter cues were manipulated by selecting letter groups that either co-occurred frequently in the language or did not. In two experiments, results revealed little or no effect of the phonological variable (syllables) but a reliable effect of the orthographic variable (letter-cue frequency). Letter cues with a low frequency of co-occurrence in the language led to better completion of the fragmented words. We interpret these findings as support for models of lexical representation that are based on orthographic properties (e.g., Seidenberg & McClelland, 1989) rather than those based on phonological constraints.     

Visual and tactile memory for 2-D patterns: Effects of changes in size and left-right orientation

Visual identification of 3-D objects depends on representations that are invariant across changes in size and left-right orientation. We examined whether this finding reflects the unique demands of processing 3-D objects, or whether it generalizes to 2-D patterns and to the tactile modality. Our findings suggest that object representation for identification is influenced greatly by the processing demands of stimulus materials (e.g., 2-D vs. 3-D objects) and stimulus modality (touch vs. vision). Identification of 2-D patterns in vision is adversely affected by left-right orientation changes, but not size changes. Identification of the same patterns in touch is adversely affected by both changes. Together, the results suggest that the unique processing demands of stimulus materials and modality shape the representation of objects in memory.     

On associations between computers and restaurants: Rapid learning of new associations on a conceptual implicit memory test

A novel event-based conceptual implicit memory test was designed to tap the development of new associations between objects and ad hoc categories. At study, participants were presented with a plausible story that linked an incongruous object (computer) with an ad hoc category (restaurant). At test, participants judged whether a given object was typically found in a restaurant. In Experiment 1, judgment time was significantly slower for the incongruous object (computer) when the story had previously linked the computer to the restaurant, relative to when it had not. Experiment 2 replicated this effect and ruled out the alternative interpretation that this interference effect was attributable to a general slowing of responses to all studied items. Unlike in prior studies, this demonstration of associative priming cannot be attributed to perceptual priming or to test awareness in memory-intact participants. The paradigm therefore offers a unique opportunity to study single-trial conceptual learning in memory-intact and memory-impaired populations.     

Peri-ictal and ictal cognitive dysfunction in epilepsy

Disturbances in cognitive function, particularly memory, are a common complaint of patients with epilepsy. Factors contributing to cognitive dysfunction are the type of epilepsy, type and frequency of seizures, anti-epileptic drugs and the location of underlying brain lesions. Whilst a great deal of attention has been paid to permanent cognitive impairment, the nature and underlying mechanisms of ictal and peri-ictal cognitive changes are poorly understood. In-depth investigation of seizure related cognitive dysfunction is of great clinical relevance, as these changes are potentially reversible and treatable, thus reducing the cumulative effect of frequent seizures. Greater knowledge of peri-ictal and ictal cognitive dysfunction would improve seizure prediction, localization of seizure focus and assessment of treatment effectiveness, greatly reducing distress and disability. This paper will review current understanding of peri-ictal and ictal cognitive dysfunction and discuss future directions for research.     

Size and reflection effects in priming: A test of transfer-appropriate processing

Prior research has suggested that priming on perceptual implicit tests is insensitive to changes in stimulus size and reflection. The present experiments were performed to investigate whether size and reflection effects can be obtained in priming under conditions that encourage the processing of this information at study and at test, as predicted by transfer-appropriate processing. The results indicate that priming was affected by a change in the physical size of an object when study and test tasks required a judgment about the real size of pictorial objects (e.g., deciding whether a zebra presented small or large on the screen was larger or smaller than a typical chair), and when the test task required the identification of fragmented pictures. However, a change in left-right orientation had no effect on priming when study and test tasks required a judgment about the left-right orientation of familiar objects, or when the test task involved the identification of fragmented pictures. This difference between size and reflection effects is discussed in terms of the differential importance of size and reflection information in shape identification.     

The Brahmin and the fakir: Suburban religiosity in the cult of Shirdi Sai baba

Shirdi Sai Baba (?‐1918), whose cult in Bangalore city, India, is the case study of this paper, was a Maharashtrian saint closely identified with both the Pandharpur tradition of Vaisnavite devotion and Sufi genealogies in the region. My thesis is that in the cult of Shirdi Sai Baba, the holy mendicant/saint (fakir/sant) paradigm was associated historically with non‐urban locations; the paradigm of the spiritual guide (guru,) and, in later years, the incarnation (avatar), is to be found associated with suburban and urban sites. The religious imagination of a cult is a behavioural, communicational and spatial model that creates particular kinds of topological domains in different historical and social milieus. It achieves its coherence within these contexts through certain ‘root paradigms’, cultural codes in the minds of carriers of traditions that shape relationships, practices, and life‐stances of individuals. While it is common to identify an urban location by certain social science variables, such as the size of a settlement, industrialisation or a sophisticated communication system, 1 will instead view the urban topos of Bangalore through the root paradigms of a religious cult.     

Generalization to novel views from view combination

Four experiments examined whether or not exposure to two views (A and B) of a novel object improves generalization to a third view (C) through view combination on tasks that required symmetry or recognition memory decisions. The results of Experiment 1 indicated that exposure to either View A or View B alone produced little or no generalization to View C on either task. The results of Experiment 2 indicated that exposure to both View A and View B did improve generalization to View C, but only for symmetrical objects. Experiment 3 replicated this generalization advantage for symmetrical but not asymmetrical objects, when objects were well learned at study. The results of Experiment 4 showed that Views A and B did not have to be presented consecutively to facilitate responses to View C. Together, the pattern of results suggests that generalization to novel views does occur through view combination of temporally separated views, but it is more likely to be observed with symmetrical objects.     

Survivors’ Advice to Service Providers: How to Best Serve Survivors of Sexual Assault

Recognizing the relatively low rate at which sexual assault survivors seek services, researchers in the last decade have turned their attention to better understanding survivors’ experiences with victim services. Surprisingly, limited research has directly asked sexual assault survivors for recommendations on how to improve victim services, including both criminal justice and community-based services. The current study builds on the existing literature to gather input from women survivors that can translate into ways to improve victim services. As part of a larger longitudinal study, the current investigation asked 224 ethnically diverse adult (aged 18–62) women survivors of recent sexual assault to provide recommendations for how victim services can best serve survivors of sexual assault at multiple time points. Nearly all women in the study (91%) offered specific recommendations on how to improve victim services. Recommendations included ensuring availability of a female provider, improving communication with survivors as well as within and between service providers, helping survivors obtain resources, believing and not blaming survivors, demonstrating greater understanding of trauma-related responses and approaching survivors with greater compassion, and implementing better training on effectively working with survivors. Implications for victim service provision are discussed.     

IMPLICIT AND EXPLICIT MEMORY FOR HAPTICALLY EXPERIENCED TWO-DIMENSIONAL PATTERNS

Abstract— Recent research with visual objects has delineated important representational differences between memory measures that tap identification (implicit tests) and measures that require episodic recognition (explicit tests). We investigated whether these differences reflect a fundamental architecture for the representation of object information in memory. In the present experiment, we contrasted identification and episodic recognition for haptically presented two-dimensional patterns. Haptic identification was not affected by elaborative processing at study, whereas haptic episodic recognition was enhanced by elaborative processing. This finding suggests important similarities in the organization of object information in the visual and haptic modalities.
