The field dependence/independence cognitive style does not control the spatial perception of elevation

Earlier work described the presence of a significant connection between an individual's ability to disregard distracting aspects of a visual field in the classical rod-and-frame test (RFT), in which a subject is required to set a rod so that it will appear vertical in the presence of a square frame that is roll tilted from vertical, and in paper-and-pencil tests, in which the subject is required to find a hidden figure embedded in a more complex figure (the Embedded Figures Test [EFT]; see, e.g., Witkin, Dyk, Faterson, Goodenough, & Karp, 1962; Witkin et al., 1954; Witkin, Oltman, Raskin, & Karp, 1971). This has led to a belief in the existence of a bipolar dimension of cognitive style that is utilized in such disembedding tasks--namely, the extent to which an individual is dependent on or independent from the influence of a distracting visual field. The influence of an inducing visual field on the perception of elevation measured by the setting of a visual target to appear at eye level (the visually perceived eye level [VPEL] discrimination) has also been found to be correlated with the RFT. We have thus explored the possible involvement of the dependence/independence cognitive style on the VPEL discrimination. Measurements were made on each of 18 subjects (9 of them female, 9 male) setting a small target to the VPEL in the presence of a pitched visual field across a range of six pitches from -30 degrees (topbackward) to +20 degrees (topforward) and on each of three tests generally recognized as tests of cognitive spatial abilities: the EFT, the Gestalt Completion Test, and the Snowy Pictures Test (SPT). Although there were significant pairwise correlations relating performance on the three cognitive tests (+.73, +.48, and +.71), the correlation of each of these three with the slope of the VPEL-versus-pitch function was not significant, as it was with the slope of the perception of visual pitch of the field (PVP)-versus-pitch function. VPEL, PVP, and a cognitive factor separated into three essentially independent factors in a multiple-factor analysis, with the three cognitive tests clustering at the cognitive factor, and with no significant loading on either of the other two factors. From the above considerations and a multiple-factor analytic treatment including additional results from this and other laboratories, we conclude that the cognitive-processing style held to be involved in the performance on the EFT and the perception of vertical as measured by the RFT is not general for egocentric space perception; it does not involve the perception of elevation.     

As the wheel turns: a centennial reflection on Freud's Three Essays on the Theory of Sexuality

Freud's theories of psychosexual development, while highly original, were anchored in the explosion of scientific studies of sex in the nineteenth century. Most of these studies were based on masturbation, homosexuality, and deviance, with little attention given to normal sexuality. Around the turn of the century, the narrow interest in pathological sexuality and sexual physiology gradually gave way to a broader interest in normal sexuality. It was in the context of these expanding studies of sexuality that Freud proposed the first psychological view of sexuality, a theory that defined sex as being at the interface between soma and psyche. Libido theory, which Freud developed, is a theory of drives and conflicts. For Freud, libido was the major force in personality development, and he posited sexual conflicts as the heart of neuroses, sexual fixations as the essence of perversions. This article traces the way Freud's libido theory has served as one of the mainsprings in the development of psychoanalytic theory. It also addresses the major revisions that have taken place in libido theory, with a focus primarily on object relations theory, and the impact of culture on the way sex and sexual mores are parsed.     

The influence of saccade length on the saccadic suppression of displacement detection

The decrease in sensitivity to spatial displacement which accompanies a voluntary horizontal saccadic eye movement was measured as a function of the length of the saccade. Threshold for detecting the displacement increased linearly from about 0.3 degrees to 1.2 degrees as saccade length increased from 4 degrees to 12 degrees. The variability (standard deviation) of the discrimination increased linearly with saccade length as well, and hence also linearly with the displacement threshold. These results, along with our previous finding that the increase is not a consequence of the saccadically generated spatiotemporal smearing of the retinal image (Li & Matin, 1990), support the proposal that displacement detection is based on a constant internal signal/noise ratio whose denominator is a measure of the variability of the extraretinal signal regarding eye position, and that the reduction in sensitivity is a result of a transient increase of this variability in the temporal neighborhood of a saccade.     

Saccadic overhead: Information-processing time with and without saccades

Information-processing time was compared for serial and spatially distributed visual presentations with performance measures that permit the separation of total time into its during-display and post-display components. For all subjects, there was a significant saccadic overhead, that is, less time was required with the serial format, which allowed data access without eye movements. However, the magnitude of the overhead decreased as task complexity increased. All subjects were able to exercise some control over the distribution of total processing time, trading off short during-display times with longer post-display times and vice versa.     

Short-lived effects of a visual inducer during egocentric space perception and manual behavior

A pitched visual inducer has a strong effect on the visually perceived elevation of a target in extrapersonal space, and also on the elevation of the arm when a subject points with an unseen arm to the target’s elevation. The manual effect is a systematic function of hand-to-body distance (Li and Matin Vision Research 45:533–550, 2005): When the arm is fully extended, manual responses to perceptually mislocalized luminous targets are veridical; when the arm is close to the body, gross matching errors occur. In the present experiments, we measured this hand-to-body distance effect during the presence of a pitched visual inducer and after inducer offset, using three values of hand-to-body distance (0, 40, and 70 cm) and two open-loop tasks (pointing to the perceived elevation of a target at true eye level and setting the height of the arm to match the elevation). We also measured manual behavior when subjects were instructed to point horizontally under induction and after inducer offset (no visual target at any time). In all cases, the hand-to-body distance effect disappeared shortly after inducer offset. We suggest that the rapid disappearance of the distance effect is a manifestation of processes in the dorsal visual stream that are involved in updating short-lived representations of the arm in egocentric visual perception and manual behavior.     

Review of Awakening the Dreamer: Clinical Journeys by Philip M. Bromberg

The current paradigm shift in psychoanalysis and related sciences is generating more powerful models of psychopathogenesis and treatment. Toward that end, in Awakening the Dreamer Philip Bromberg masterfully integrates psychoanalytic, developmental, trauma, and neurobiological data to explore the bottom-line defense of dissociation. In this review I offer a neuropsychoanalytic perspective of the origin of pathological dissociation, focusing on the enduring impact of this early defense against attachment trauma and its growth inhibiting impact on the development of the biological substrate of the human unconscious, the right brain. Patients with a history of abuse or neglect frequently access pathological dissociation in response to relational stressors to block the emotional pain that accompanies overwhelming affective states. And yet there is a cost. The characterological use of this affect regulating strategy induces a failure of integration of the higher right hemisphere with the lower right brain, thereby inducing an instant collapse of both subjectivity and intersubjectivity in the short term and a blockade of emotional development in the long term. Bromberg's creative book is an excellent example of how effective clinical work with such patients incorporates the current paradigm shift from not only cognition to affect but also repression to dissociation.     

Self-Esteem and Its Relationship to Mental Health and Quality of Life in Adults with Cystic Fibrosis

Research from the general population indicates an important role for self-esteem in mental health, but limited research in this area exists in the cystic fibrosis (CF) literature. This study aimed to explore the predictive value of self-esteem and health-related quality of life (HRQoL) in mental health symptoms in adults with CF. Seventy-four participants, recruited online, completed the Clinical Outcomes in Routine Evaluation-Outcome Measure 34 (CORE-OM), Rosenberg Self-esteem Scale and Cystic Fibrosis Questionnaire-Revised (CFQ-R). Comparably high levels of self-esteem were found, but HRQoL was lower than previous research. Thirty percent of participants scored within the clinical range for mental health difficulty. Hierarchical regression, controlling for gender, explored the value of four CFQ-R subscales (physical, social, emotional and role functioning) and self-esteem in predicting CORE-OM total score. Gender accounted for 8.2 % of the variance in mental health scores while the five independent variables accounted for a further 73.0 % of variance. Of the five variables, CFQ-R emotional functioning and self-esteem were significant predictors of mental health symptoms. Results are discussed in relation to clinical implications and potential uses for internet technologies to promote socialisation.     

The impact of psychological therapies on violent behaviour in clinical and forensic settings: A systematic review

Violent behaviour is a serious problem in terms of the impact on victims, quality of life for perpetrators, and the financial burden on the prison service, the health sector, and society generally. However, to date there is not a general consensus as to how this can be managed other than removing the perpetrators from communities. Incarceration can be on an indeterminate basis or for a short period of time before reintegration into society, depending on the gravity of the offence. This systematic review critically examines the existing research literature on psychotherapeutic interventions for violent behaviour in forensic and clinical populations. Five databases were searched, selected journals were hand searched, and authors of identified papers were contacted in efforts to obtain relevant unpublished work. The first author and a colleague independently evaluated the eligibility of all studies identified, abstracted data, and assessed study quality. The overall findings provide tentative support for the utility of psychotherapeutic interventions in reducing aggressive behaviour in forensic and psychiatric patients with a history of violent behaviour.     

Psychological functioning and well-being among Ghanaian women: A brief report

This study examined correlates of psychological well-being and distress among women in Accra, Ghana. A total of 200 women between 18 and 65 years completed measures of psychological well-being and distress. Independent t-test and One-way ANOVA F-test analysis of the data suggested differences among the women in their psychological well-being and distress levels by their religiosity, education, and monthly income. Christian women reported higher psychological well-being compared to non-Christians. Religiosity, higher education, and income appear to be protective resources against psychological distress among Ghanaian women.
