On creating a psychoanalytic mind

The term process knowledge is introduced to highlight a particular way of analyzing that centers on how our patients gain knowledge. It is suggested that analyzing with heightened awareness to process knowledge is crucial for the patients' capacity for self-analysis, and differs from helping patients primarily gain knowledge of their unconscious fantasies and conflicts as the primary curative factor in psychoanalysis.     

Individual Differences in the Encoding Processes of Egocentric and Allocentric Survey Knowledge

This study examined how different components of working memory are involved in the acquisition of egocentric and allocentric survey knowledge by people with a good and poor sense of direction (SOD). We employed a dual‐task method and asked participants to learn routes from videos with verbal, visual, and spatial interference tasks and without any interference. Results showed that people with a good SOD encoded and integrated knowledge about landmarks and routes into egocentric survey knowledge in verbal and spatial working memory, which is then transformed into allocentric survey knowledge with the support of all three components, distances being processed in verbal and spatial working memory and directions in visual and spatial working memory. In contrast, people with a poor SOD relied on verbal working memory and lacked spatial processing, thus failing to acquire accurate survey knowledge. Based on the results, a possible model for explaining individual differences in spatial knowledge acquisition is proposed.     

Inter-hemispheric remapping between arm proprioception and vision of the hand is disrupted by single pulse TMS on the left parietal cortex

Parietal cortical areas are involved in sensori-motor transformations for their respective contralateral hemifield/body. When arms of the subjects are crossed while their gaze is fixed straight ahead, vision of the hand is processed by the hemisphere ipsilateral to the arm position and proprioception of the arm by the contralateral hemisphere. It induces interhemispheric transfer and remapping. Our objective was to investigate whether a single pulse TMS applied to the left parietal cortical area would disturb interhemispheric remapping in a similar case, and would increase a simple reaction time (RT) with respect to a control single pulse TMS applied to the frontal cortical area. Two LED were superimposed and located in front of the subjects on the saggital axis. Subjects were asked to carefully fixate on these LED during each trial. The lighting of the red LED was used as a warning signal. Following the green one was illuminated after a variable delay and served as a go-signal. The hand for the response was determined before the start of each trial. TMS was applied to the left parietal, the left frontal cortical areas, or not applied to the subject. Results revealed that: (1) Irrespective of its location, single pulse TMS induced a non-specific effect similar to a startle reflex and reduced RT substantially (15 ms on average) with respect to a control condition without TMS (mean value = 153 ms). (2) Irrespective of TMS, RT were shorter when the right or the left hand was positioned in the right visual hemi-field (i.e. normal and crossed positions respectively). (3) Finally, RT increased when single pulse TMS was applied to the left parietal area and when hands were crossed irrespective of which hand was used. We concluded that interhemispheric sensori-motor remapping was disrupted by a single pulse TMS that was applied to the left parietal cortex. This effect was also combined with some visual attention directed towards the hand located on the right visual hemi-field.     

Shock tactics to counter AIDS: The australian experience

Abstract

The use of shock tactics to motivate people to learn more about AIDS and to take appropriate protective action characterised the approach adopted by the national health authorities in Australia during 1987. The rationale underlying this approach is critically examined, particularly in the light of results obtained from surveys of community concern and knowledge about AIDS in the state of South Australia before the campaign and after it had been in progress for some five months. Contrary to expectations no significant increases in either personal or social concern were found; in fact, among older respondents personal concern had decreased significantly. Levels of knowledge about AIDS, in general, remained unchanged, apart from an increase in acceptance of the safety of blood transfusions from a very low to a somewhat higher level. Among a minority of respondents (29%) who approved of the campaign and also believed they had been influenced by it, personal and social concern about AIDS, but not knowledge, was significantly greater than among others. The view that fear-inducing techniques can be used to bring about increases in knowledge about AIDS was not supported, although some positive effects on the social attitudes of respondents most affected by the campaign are suggested.     

Magnitude and determinants of behavioral risk reduction: Longitudinal analysis of a cohort at risk for AIDS

The magnitude and predictors of longitudinal behavioral change are reported in a cohort of homosexual men at risk for AIDS. Self-reports of sexual behavior were obtained at two points in time separated by an interval of approximately six months. These self-reports were used to construct both dichotomous and continuous measures of changes in behavior consistent with reduction in the transmission of the AIDS virus (HIV). Although there was considerable variability in behavior. mean changes were consistently in the desired direction. Avoidance of anonymous sexual partners, monogamy, and modification of receptive anal sex to reduce exposure to semen by condom use or withdrawal prior to ejaculation appeared to be especially important in this cohort. Both multiple linear regression and multiple logistic regression were used to examine the relationship between a model of health behavior and these outcomes. Variables examined included knowledge of AIDS. perceived risk of AIDS. the perceived efficacy of behavior in reducing AIDS risk, difficulties with sexual impulse control, belief in biomedical technology to provide a prevention or cure, social norms supportive of behavioral change, and gay network affiliation. Of all these factors, only the availability of supportive peer norms was consistently, significantly and positively related to multiple measures of outcome. Differences between these analyses and longitudinal analyses reported elsewhere are discussed. These results suggest the policies regarding HIV antibody testing should be developed cautiously. taking account of the failure of a sense of risk to predict subsequent behavioral change. They also emphasize the important role of gay organizations in developing social norms supportive of behavioral risk reduction.     

Validation of a new multidimensional health locus of control scale (form c) in asthma research

Abstract

This study developed and validated an Asthma Multidimensional Health Locus of Control (AMHLC) scale using 186 asthmatics aged 13 to 55 years recruited from 46 pharmacies in the Hunter Valley, Australia. The construct validity and internal consistency of the scale were demonstrated using principal components factor analysis and Cronbach's alpha respectively. Although correlations were modest, findings indicate that asthmatics with higher “Powerful Others” locus of control perceived they had a better quality of doctor-patient relationship; the opposite was found for those with higher “Chance” scores. Powerful Others orientation was also associated with expectations and valuation of services doctors' provide. Knowledge of asthma was not related in the expected direction with the new scale, nor were clinical indices of asthma severity. Younger asthmatics had higher Chance scores while older asthmatics tended toward higher Powerful Others orientation. Overall, the AMHLC instrument achieved suitable measurement properties to allow further investigation of health care behavior in people with asthma.     

Biases in intuitive reasoning and belief in complementary and alternative medicine

Very little is known about the reasoning underlying beliefs in complementary and alternative medicine (CAM). This study examined whether CAM beliefs can be better explained with intuitive reasoning, paranormal beliefs and ontological confusions of physical, biological and mental phenomena than with 12 variables that have typically been used to explore the popularity of CAM, namely gender, education, income, age, health, desire to control treatment, satisfaction with conventional medicine and world view (unconventional, feministic, environmentalist, exotical and natural). A representative sample of Finnish people (N = 1092) participated in the study. The results showed that intuitive thinking, paranormal beliefs and ontological confusions predicted 34% of the variation in CAM beliefs, whereas the 12 other variables increased the prediction only by 4%. The results help to explain individual, cultural and situational differences in the popularity of CAM and to differentiate between CAM statements that can be scientifically examined from those that cannot.     

Linear-parabolic shift of initially sharp interface in AB diffusion couple above the ordering temperature

It is shown that initially sharp interface in AB diffusion couple, above the ordering temperature, can shift with anomalous kinetics, i.e. deviations from the parabolic growth kinetics are possible. The initial slopes of the shift versus time functions can be even unity for large diffusion asymmetry (the ratio of diffusion coefficients of the parent materials in orders of magnitude) and gradually decrease to 0.5 at larger distances (longer times). This is in accordance with earlier results obtained in phase separating systems. It is shown that from the results of simulations the crossover thickness, X*, between the linear and parabolic regimes can also be calculated, and the applicability of the linear–parabolic law is confirmed. Furthermore, it is illustrated that the crossover thickness depends exponentially on the diffusion asymmetry parameter, with the exponent close to the value obtained from analytical estimations.     

Some Evidence is False

According to some philosophers who accept a propositional conception of evidence, someone's evidence includes a proposition only if it is true. I argue against this thesis by appealing to the possibility of knowledge from falsehood.     

South African Educators' Voice on the Potential Role of Traditional Healers (THs) in Education Support Services

The aim of this qualitative research was to explore and describe perceptions of the potential role of traditional healers in education support services. Participants were 42 teachers (males = 13, females = 29) from a school district in the Eastern Cape province of South Africa. Interview and questionnaire data were collected and analysed, using a phenomenological method. Two main themes emerged from the analysis for the role of THs as education support providers: as 1) representatives of African culture and 2) contributors towards harmonising diversity in schools. The recommendations made were in line with the findings.
