Why There Cannot be Any Such Thing as “Time Travel”

Extending work of Wittgenstein, Lakoff and Johnson I suggest that it is the (spatial) metaphors we rely on in order to conceptualise time that provide an illusory space for time‐travel‐talk. For example, in the “Moving Time” spatialisation of time, “objects” move past the agent from the future to the past. The objects all move in the same direction – this is mapped to time always moving in the same direction. But then it is easy to imagine suspending this rule, and asking why the objects should not start moving in the opposite direction. This is one way of generating the idea of time‐travel “back” into the past. Time‐travel‐talk essentially involves the unaware projection of fragments of our time‐talk – taken from powerful conceptual metaphors – onto the nature of reality itself. Understanding this dissolves away the charm and attractions of such talk.     

Glucocorticoid response to changes in enclosure size and human proximity in the Persian onager (Equus hemionus onager)

This study investigated glucocorticoid (GC) responses to season and changes in enclosure size and human proximity in the Persian onager (Equus hemionus onager). Enzyme immunoassays were validated to measure GC metabolites in urine and feces (fGCM). Fecal samples were collected from 10 female onagers while in a large pasture, after transport to smaller yards (in greater proximity to people), and 2 months thereafter. Urine samples were collected for 1 year while females were in smaller yards to examine seasonal GC activity. Approximately, 2-fold increases (P < 0.05) were observed in fGCM levels after transport from pasture to yards with increased human exposure, followed by a rapid decline (within -17 days) to baseline (pasture) values. However, responses varied among onagers during the 30 days after translocation, with one female failing to acclimate. Mean fGCM concentrations in smaller yards 2 months after transport were comparable to those in pasture. Seasonal GC concentrations were lowest (P < 0.05) during winter, indicating modest seasonal variability. Results demonstrate an acute increase in GC secretion in Persian onagers that moved from large to small enclosures coincident with increased human activities. Most animals acclimated within 3 weeks, suggesting that this rare equid has retained mechanisms to acclimate to marked alterations in an ex situ environment.     

Society,spirit & ritual Morphic resonance and the collective unconscious part II

Rupert Sheldrake i s a theoretical biologist whose book, A New Science of Life: The Hypothesis of Formative Causation, continues to evoke a storm of controversy. Following i s the second i n a series of articles wherein Sheldrake presents his ideas for amplifying Jung's concept of the collective unconscious and archetypal psychology. He concluded his first article with these words:

The approach I am putting forward is very similar to Jung's idea of the collective unconscious. The main difference i s that Jung's idea was applied primarily to human experience and human collective memory. What I am suggesting i s that a very similar principle operates throughout the entire universe, not just in human beings. If the kind of radical paradigm shift I am talking about goes on within biology - if the hypothesis of morphic resonance i s even approximately correct - then Jung's idea of the collective unconscious would become a mainstream idea. Morphogenic fields and the concept of the collective unconscious would completely change the context of modern psychology.     

We all live in Germany but … Ingroup projection,group‐based emotions and prejudice against immigrants

Immigration, cultural diversity and integration are among the most central challenges for modern societies. Integration is often impeded by negative emotions and prejudices held by the majority members towards immigrants in a common society. Based on the ingroup projection model (Mummendey & Wenzel, 1999), we examined the impact of perceived relative ingroup prototypicality on intergroup emotions and prejudice. Additionally, we examined whether this impact is causal and explored the issue of causality in more detail contrasting a linear causal model with bi‐directional or reciprocal causality. Hypotheses were tested in a study with a two‐wave panel of majority members (N=1085) in Germany. We examined the proposed relations between relative ingroup prototypicality, intergroup emotions and prejudice and determined the causal direction of these relationships. Results support the predictive power of relative ingroup prototypicality on intergroup emotions and prejudice. Moreover, most causal relations between our measures are reciprocally causal. We discuss the implications of these findings for the general conception of prejudice and intergroup emotions. Copyright © 2009 John Wiley & Sons, Ltd.     

Forgive and Forget? Antecedents and Consequences of Intergroup Forgiveness in Bosnia and Herzegovina

The present study examines the effects of contact and common-ingroup identification on intergroup forgiveness and outgroup behavioral tendencies. A sample of Bosnian Muslims (N  =  180) were asked to report their readiness to forgive the misdeeds committed by Bosnian Serbs during the 1992–95 war in Bosnia and Herzegovina. A path analysis of the presumed antecedents and consequences of forgiveness revealed that frequent and good quality contact with members from the perpetrator group predicted forgiveness (positively) and desire for social distance (negatively). Moreover, the positive relationship between contact and forgiveness was mediated by empathy and trust towards the outgroup and by perceived outgroup heterogeneity. Common-ingroup identification was also found to be positively associated with forgiveness and negatively with social distance towards the outgroup. Finally, intergroup forgiveness also predicted social distance from the outgroup. The theoretical and applied implications of these findings are discussed.     

The impact of stimulus and response variability on S-R correspondence effects

Six experiments investigated how variability on irrelevant stimulus dimensions and variability on response dimensions contribute to spatial and nonspatial stimulus-response (S-R) correspondence effects. Experiments 1-3 showed that, when stimuli varied in location and number, S-R correspondence effects for location or numerosity occurred when responses varied on these dimensions but not when responses were invariant on these dimensions. These results are consistent with the response-discrimination account, according to which S-R correspondence effects should only arise for a dimension that is used for discriminating between responses in working memory. Experiments 4-6 showed that, when responses varied in location and number, both invariant and variable stimulus number produced correspondence effects in S-R numerosity. In summary, the present results indicate that the usefulness of a particular dimension for response discrimination can be sufficient for producing S-R correspondence effects, whereas variability of a stimulus dimension is not sufficient for producing such effects.     

Nature against nurture: calcification in the right thalamus in a young man with anorexia nervosa and obsessive-compulsive personality disorder

This report describes the case of a young man with a large calcification in the right thalamus that was first diagnosed at 9 years of age. Case history reveals specific eating rituals and other obsessive-compulsive personality traits during the patient's childhood and adolescence, fulfilling diagnostic criteria of obsessive-compulsive personality disorder. After a critical life event the patient develops anorexia nervosa. We suggest that our case and further literature provide evidence for an involvement of specific thalamic structures, such as the dorsomedial nucleus, in the development of anorexia nervosa. Furthermore, the treatment of the patient by a combined psychotherapeutic and pharmacotherapeutic approach is described. We focus on the beneficial effect of the atypical antipsychotic olanzapine, which can induce weight gain by an increase of leptin levels.     

Improving Children's Attitudes Toward Refugees: An Evaluation of a School‐Based Multicultural Curriculum and an Anti‐Racist Intervention1

We evaluated the impact of the Friendship Project, a program designed to improve elementary school children's attitudes toward refugees. Participants either received 4 weekly lessons based on the program, or they received no lessons. All participants completed attitude measures before and after implementation of the program. Half completed the post‐test 1 week after completion of the program, while the other half completed the post‐test 7 weeks after its completion. The program led to more positive attitudes toward refugees in the short term, but not in the long term. Moreover, although it did not increase empathy, the program increased the proportion of participants who preferred an acculturation strategy of integration and reduced the number of participants who had conflictual acculturative fit.     

Generalization of positive attitude as a function of subgroup and superordinate group identifications in intergroup contact

The role of category salience in mediating the effects of intergroup contact was examined. One theoretical model proposes that some psychological salience of subgroup categories is necessary to facilitate the generalization of attitude change beyond the immediate contact situation. Another argues that a re‐categorization of the subgroups into a new superordinate category is more beneficial, whilst a third suggests that de‐categorizing the situation entirely is optimal. An alternative view, which combines the first two models, proposes a Dual Identity strategy (simultaneous high superordinate and high subgroup categorization) as an important mediator of the relationship between contact variables and intergroup attitudes. In the study, participants (N = 114) undertook a cooperative intergroup task under four conditions of category salience: ‘subgroup’, ‘superordinate’, ‘superordinate and subgroup’, and ‘no group salience’. Evaluative ratings and symbolic reward allocations both for the groups encountered (contact) and those outside the situation (generalization) provided measures of intergroup bias. Bias within the contact situation was mainly eliminated in all conditions. However, on the more generalized bias measures, only the ‘superordinate’ and ‘superordinate and subgroup’ (Dual Identity strategy) conditions maintained this low level; in the other two conditions intergroup bias resurfaced. A combination of the first two models is proposed. Copyright © 2002 John Wiley & Sons, Ltd.
