Evaluating a split processing model of visual word recognition: effects of orthographic neighborhood size

The split fovea theory proposes that visual word recognition of centrally presented words is mediated by the splitting of the foveal image, with letters to the left of fixation being projected to the right hemisphere (RH) and letters to the right of fixation being projected to the left hemisphere (LH). Two lexical decision experiments aimed to elucidate word recognition processes under the split fovea theory are described. The first experiment showed that when words were presented centrally, such that the initial letters were in the left visual field (LVF/RH), there were effects of orthographic neighborhood, i.e., there were faster responses to words with high rather than low orthographic neighborhoods for the initial letters ('lead neighbors'). This effect was limited to lead-neighbors but not end-neighbors (orthographic neighbors sharing the same final letters). When the same words were fully presented in the LVF/RH or right visual field (RVF/LH, Experiment 2), there was no effect of orthographic neighborhood size. We argue that the lack of an effect in Experiment 2 was due to exposure to all of the letters of the words, the words being matched for overall orthographic neighborhood count and the sub-parts no longer having a unique effect. We concluded that the orthographic activation found in Experiment 1 occurred because the initial letters of centrally presented words were projected to the RH. The results support the split fovea theory, where the RH has primacy in representing lead neighbors of a written word.     

Identity and oppression: differential responses to an in-between status

Oppression operates at various levels, with varying degrees of negativity, and groups respond in markedly different ways. In this paper, the in-between status of the colored South African group is used to illustrate issues of identity and oppression under the Apartheid system—and differing ways in which oppression was experienced and used. The colored group had many social advantages over Blacks, but were also used to oppress that group. Habituation, accommodation, and relative advantage were identified as dynamics within the broader context of power and privilege that contributed to cultural and psychological marginality and status ambivalence of the coloreds. These processes must be understood within the historical, social, and political context of the community. What is evident from the data is that groups and individuals can take up various positions along a continuum of oppressor—oppressed, depending upon the contexts, time, and social and legal relationships involved in their interactions.     

Continuous Performance Test Performance in a Normative Epidemiological Sample

A 14-min continuous performance test (CPT) requiring a high rate of responding was administered to a probability-weighted random sample of 816 9–17-year-old children drawn from a population of 17,117 children in an ongoing epidemiological and longitudinal study in Western North Carolina. Systematic main effects of improved performance with older age were found in this age range for all variables, including reaction time (RT), RT standard error, errors of omission, errors of commission, and signal detection parameters (d' and ). Significant gender main effects included more impulsive errors, less variability, and faster RT by males, with no interactions between age and gender. There were no main effects of ethnicity or interactions of ethnicity with age and/or gender. Large main effects of interstimulus interval (ISI; 1, 2, or 4-s intervals) and time block were present for most CPT performance measures. The normative data from the CPT should provide a useful framework for interpreting similar data in future studies of child and adolescent psychopathology.     

Research Report: Students' knowledge of abnormal psychology

The present study aims to compare whether final year psychology students (n = 26) could answer more items on a multiple choice questionnaire (MCQ) correctly on abnormal psychology than prospective psychology candidates (n = 77) and final year engineering students (n = 26). The three groups of students completed MCQs in five different fields of abnormal psychology namely; eating disorders, schizophrenia, anxiety disorders and depression, sexual disorders, and personality and compulsive disorders, respectively. They were also asked to indicate their confidence level in relation to the accuracy of the answers they had given. The results showed that final year psychology students scored higher on levels of accuracy, as well as confidence on all measures compared to the two other groups. On the subject of sexual disorders, engineering students scored higher than prospective psychology students. Implications of the present findings are discussed.     

Gender and locus of control correlates of body image dissatisfaction

The study concerned sex and various locus of control correlates of body image satisfaction. The results indicated that men and women differ significantly in the degree and in the direction of dissatisfaction towards their bodies, which were consistent with the culturally defined ideals for men and women. Significant differences were also observed regarding self-perceptions, suggesting that women more than men are more likely to suffer from depression and have lower self-esteem which was itself associated with body image satisfaction. Individual beliefs about perceived control towards achieving an ‘ideal’ body shape were assessed using a new locus of control scale which correlated significantly with two scales measuring attitudes relating to body shape. The results from this new scale suggest that perceived locus of control beliefs are important predictors of the resulting behaviours and self-perceptions associated with body shape satisfaction and dissatisfaction.     

The Effects of Health Threat Seriousness and Personal Efficacy upon Intentions and Behavior1

Eighty dental patients were pretested with a scale measuring health locus of control and then exposed to a persuasive communication designed to manipulate their beliefs about the seriousness of periodontal disease and their susceptibility to it. The high seriousness condition increased feelings of fear, concern, and threat as well as intentions and reported compliance with recommended oral hygiene procedures. However, patient's perceived personal efficacy in performing the recommended behavior was the most important predictor of subsequent behavior. The implications of the results for Roger's protection motivation theory are discussed.

Lay theories of rape

This study examined ‘la’ theories of rape and compared them to numerous academic theories. One hundred and thirty subjects-52 male, 78 female-completed two questionnaires, one regarding attitudes/beliefs to rape in general, the other on the possible causes of the crime. Factor analysis revealed five factors in the attitude/belief items: Subjects generally perceived the rape victim as moral, responsible, and unprovoking; the rapist was perceived as a repressed delinquent. Subjects agreed with two of the six explanation factors, seeing rape as resulting from a desire for aggression induced by societal factors. The rapist was believed to be a psychopath. Lay theories did not correspond to any formal academic rape model or explanations. Beliefs about the causes of, and attitudes to rape, correlated highly. Age was the greatest determinant of perspective; older subjects believed more in victim precipitation. Suggestions are made for further research in this comparatively neglected area.     

Effects of programme context on memory of humorous television commercials

This study examined the effects of programme context on the memory of humorous television advertisements among a youth sample aged 16 to 18 years. Additionally, the relationship between the enjoyment and involvement properties of the programme and memory for advertisements were investigated. An experimental design was developed to test the memory for a set of six humorous and a set of six non-humorous advertisements within two programme contexts—a news bulletin and a comedy show. Findings indicated that unaided recall for advertisements was affected by programme type with memory for advertising being better from news than from comedy. Further, memory for humorous advertisements was better than that for non-humorous advertisements. Audience involvement with, and enjoyment of, the surrounding programme were found to be associated with poorer memory for advertisement content. Copyright © 1998 John Wiley & Sons, Ltd.     

Therapeutic Utility of Discussing Therapist/Client Intersectionality in Treatment: When and How?

The impact of the therapeutic alliance on positive clinical outcomes has been established in the literature; however, literature is lacking on how the intersection of therapist and client identities influences this process. We propose that the relational intersectionality resulting from similarities or differences in therapist and client identities has the potential to impact the bonds, tasks, and goals of treatment (key components of the therapeutic alliance; Bordin, 1979) depending on how it is addressed or avoided in therapy. In this paper, we present a model containing pragmatic steps therapists can follow to navigate these conversations with clients in a way that is therapeutically beneficial and culturally sensitive and attuned. Additionally, we provide suggestions for using the proposed model to train new student therapists (or expose experienced therapists) to ideas of intersectionality and social justice by reflecting on the intersection of their own identities, acknowledging dynamics of power and oppression, and understanding how this could shape their relationship with clients.
