Cue competition effects in the planarian

The learning abilities of planarian worms (Dugesia tigrina) were assessed by using a number of Pavlovian conditioning paradigms. Experiment 1 showed that planaria were susceptible to basic conditioning in that they readily developed a conditioned response to a change in ambient luminance when it was consistently paired with an electric shock over a number of trials. In Experiment 2, the change in luminance was presented in a compound with a vibration stimulus during conditioning. Subsequent tests revealed poor conditioning of the elements compared with control groups in which the animals were conditioned in the presence of the elements alone, an instance of overshadowing. In Experiment 3, pre-training of one of the elements before compound conditioning resulted in blocking of learning about the other element. These results add to other studies that have reported cue competition effects in animal species belonging to different phyla (chordate, mollusk, arthropod), suggesting that learning in these phyla could be ruled by similar principles. The results are discussed adopting an evolutionary-comparative approach.     

Putting the ‘heart’ back into community psychology: some South African examples

In this paper we explore the impact of emotional dynamics in the field of community psychology and the value of psychodynamic concepts in making sense of this. Emotional processes have often not been very well acknowledged or conceptualized in writing in the area of community psychology practice. This neglect is understandable given the individualizing, pathologizing and medicalizing assumptions underlying many psychological theories of emotion. Psychodynamic ideas may, however, make a useful contribution to understanding central concerns in community psychology in so far as they are able to shed light on emotional processes in groups, the political determinants of emotional response and the emotional dynamics of power, which are all central to the thinking of community psychologists. Using examples drawn from a long-term programme of consultation to community-based services in South Africa, we explore the potential of psychoanalytic understandings of emotional processes in illuminating some of the complexities and challenges faced in developing effective community partnerships and working towards the empowerment of communities.     

Going the distance: Extra-symbolic contributions to the symbolic control of spatial attention

Over the past 30 years, researchers have used symbolic cues such as spatial words and arrows to direct observers' attention to the location of target objects that appear at a single, fixed distance in simple visual environments; however, they have done so by using symbolic cues that provide only partial—directional—information about the spatial location of target objects. Thus, it remains unclear whether observers can only shift their attention broadly in the cued direction in response to these cues or whether they can shift their attention to the specific location of the target by combining an expectation about direction (derived from apprehension of the directional cue) with an expectation about distance (derived from some extra-symbolic cue). The results of two experiments showed that observers do shift their attention to relatively coarse spatial locations by combining expectancies about direction and distance, and that the extent to which observers do so is modulated by the presence of visible markers and the expected distance of the target. These findings are important because they provide the first evidence that extra-symbolic information about distance contributes to the symbolic control of spatial attention.     

Mediators of the relationship between media literacy and body dissatisfaction in early adolescent girls: Implications for prevention

This study examined in young adolescent girls the fit of a theoretical model of the contribution of media literacy to body dissatisfaction via the mediating influences of internalisation of media ideals and appearance comparisons. Female Grade 7 students (N = 469) completed self-report assessments of media literacy, internalisation, appearance comparisons, body dissatisfaction, and media exposure. Strong, significant inverse associations between media literacy and body dissatisfaction, internalisation, and appearance comparisons were observed. Path analysis revealed that a slightly modified revision of the model provided a good fit to the data. Specifically, body dissatisfaction was influenced directly by appearance comparisons, internalisation, and body mass index, and indirectly by media literacy and media exposure. Indirect pathways were mediated by appearance comparisons and internalisation. Thus, a relationship between media literacy and eating disorder risk factors was observed. Findings may explain positive outcomes of media literacy interventions in eating disorder prevention.     

Investigation of Body Comparison Among Adolescent Girls1

Grade differences in appearance and nonappearance social comparisons, and targets for body comparison were examined in adolescent girls. A model describing potential contributors to, and consequences of, body comparison tendency was examined. Girls (n= 545) completed measuring social comparisons, targets for comparisons, dieting in response to comparisons, body attitudes, eating patterns, psychological variables, height, and weight. Appearance and nonappearance social comparisons increased with age. Girls reported comparing their bodies most frequently with peers and fashion models. Body comparison tendency was significantly predicted by: importance of thinness, internalization of socio‐cultural ideal, friend concern with weight, body image instability, competitiveness, grade, public self‐consciousness, perfectionism, and family concern with weight. Predictors of dieting in response to body comparison were also explored.     

An ‘Extra Legible Illustration' of the Christian Faith: Medicine,medical ethics and missionaries in the Arabian Gulf1

This article presents a view of missionary medicine in the Gulf and the ethical issues missionary medical practices evoked. It shows that, as both physicians and missionaries, and seeing themselves as an 'extra legible illustration' of the Christian faith (Paul Harrison, Doctor in Arabia, New York, John Day Co., 1940, 23-4), the missionary physicians gave selflessly to provide the best medical care possible according to their individual abilities and given the environment in which they worked. At the same time, they experimented, took risks that were sometimes unnecessary and were forced to make ethical choices that challenged their Christian moral compass. Furthermore, given the remoteness of their stations, they were absolved from professional oversight and second-guessing by patients who had nowhere else to turn. Drawing on this paradox of self-sacrifice and self-service, of Christian benevolence and imperial posturing, the article considers to what extent the mission was an exercise in altruism or imperialism.     

Cork Older Adult Intervention Project: Outcomes of a gestalt therapy group with older adults

The study investigated the effects of a gestalt therapy group with older adults. A total of 43 adults, 65 years or older, were randomised into treatment and assessment control groups of 22 and 21 respectively. ANCOVA results indicated that group therapy participants reported less anger control and more overall expression of anger than the control participants. In addition, they were significantly more agreeable and less hostile and more clear-headed and less confused at the end of the group. These findings were supported by reported emotional changes. Younger group participants were significantly more composed and less anxious than younger control group members. Qualitative results further illustrated this reduction in anxiety. Participants significantly increased their level of clear-headedness and were less confused. Qualitative evidence also illustrated their clear-headedness and agreeableness. Exploratory analysis illustrated substantial learning about oneself by group participants.
