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.     

Emotional and hemispheric asymmetries in shifts of attention: an ERP study

Inhibition of return (IOR) refers to the larger response time to cued targets appearing at long cue-to-target intervals. Given emotion-attention interactions and associated visual field (VF) asymmetries, we examined the effects of emotions and hemispheric processing on object- and location-based IOR. We expected reduced IOR and right hemispheric bias accompanied by differences in event-related potentials (ERPs) including lack of suppression of cued N1 and enhancement of Nd components for sad targets. Reaction times and ERPs were recorded in an exogenous cuing detection task using happy and sad schematic faces. Results revealed reduced IOR for left compared to right VF with sad faces but no such asymmetry for happy faces. Cued N1 amplitudes were suppressed for happy targets but not for sad targets presented to the left VF. Nd amplitudes were enhanced for right-hemispheric sad faces especially with object-based IOR. The results indicate right-hemispheric advantage in the capture of attention by negative emotion especially with object-based selection.     

When expressing forgiveness backfires in the workplace: victim power moderates the effect of expressing forgiveness on transgressor compliance

Expressing (vs. withholding) forgiveness is often promoted as a beneficial response for victims. In the present research, we argue that withholding (vs. expressing) forgiveness can also be beneficial to victims by stimulating subsequent transgressor compliance – a response that is valuable in restoring the victim’s needs for control. Based on deterrence theory, we argue that a victim’s withheld (vs. expressed) forgiveness promotes transgressor compliance when the victim has low power, relative to the transgressor. This is because withheld (vs. expressed) forgiveness from a low-power victim elicits transgressor fear. On the other hand, because people are fearful of high-power actors, high-power victims can expect high levels of compliance from a transgressor, regardless of whether they express forgiveness or not. A critical incidents survey (Study 1) and an autobiographic recall study (Study 2) among employees, as well as a laboratory experiment among business students (Study 3), support these predictions. These studies are among the first to reveal that withholding forgiveness can be beneficial for low-power victims in a hierarchical context – ironically, a context in which offering forgiveness is often expected.     

Bullying Behaviors and Victimization Experiences Among Adolescent Students: The Role of Resilience

The role of resilience in the relationship between bullying behaviors, victimization experiences, and self-efficacy was examined. Participants were 393 (191 young men, 202 young women) adolescents (M age = 15.88 years, SD = 0.64 years) from schools in Coimbatore, India, who completed scales to assess bullying behaviors and victimization experiences, resilience, and self-efficacy. Multigroup structural equation modeling, with separate groups created according to participant gender, revealed that resilience mediated the relationship between bullying behaviors and self-efficacy in young men. Young men engaged in bullying behaviors and experienced victimization more frequently than young women. The findings of the study have implication for designing intervention programs to enhance resilience among adolescents and young adults to enable them to manage bullying behaviors.     

Cross-Cultural Evaluation of the International Affective Picture System on an Indian Sample

The International Affective Picture System (IAPS) is widely used in emotion and attention research. Currently, there is neither a standard database of affective images for use in research with Indian population nor data on the way people from India respond to emotional pictures in terms of different dimensions. In the present study, we investigated whether self-reported Indian ratings are comparable to the original normative ratings (based on a North American sample) to evaluate its usability in Indian research context. The ratings were obtained from a sample of eighty Indian participants (age range?=?18 to 29 years, M _age?=?23.7, SD?=?2.67, 45 % females) on a stratified representative sample of 100 IAPS pictures. Similar to the normative data collected from the North American sample in the original IAPS database, the ratings were collected across three dimensions – valence (how pleasant/attractive or unpleasant/aversive), arousal (how calm or excited was the intensity of activation), and dominance (how controlling). Our results indicate similarities in valence ratings, but differences in arousal and dominance ratings between the Indian and the North American samples. The relationship between arousal and valence showed a similar (but less curved) boomerang shaped distribution seen with the North American sample. Unlike the North American sample, slopes were higher and intercepts were different for the Indian sample. However, the Indian sample also showed positivity offset and negative bias like the North American sample. These affective ratings show a fair amount of similarity but care is needed especially with arousal values in using these pictures for research with Indian population. While there are subtle differences in the relationship between different affective dimensions, there are also major similarities across cultures in affective judgments.     

Soul murders,wolf mother: Re-reading the Mowgli stories of The Jungle Book in a contemporary psychoanalytic perspective

Kipling’s (1894) ‘Mowgli stories’ a trio of tales set in India and written by an Englishman during the colonial period, are a natural bedfellow with cultural psychoanalysis; an approach to the unconscious that takes into account regional geography. While psychoanalysis’ interest in The Jungle Book began early and affectionately with Freud, both he and his successors read Kipling from the viewpoint of a certain geography and history associated with early European psychoanalysis. As such, psychoanalytic and post-colonial literary ways of reading Kipling, have, like the East and West of the writer’s ballad, generally resisted meeting. In this paper, I re-read the Mowgli Stories of Kipling’s Jungle Book with an awareness of how geography might have affected the subjectivity of prior analytic readers, offering the Mowgli stories anew to modern – by which I mean post-colonial – readers.
