Intersecting heterologies

The author proposes that it has largely been underestimated that the therapeutic community is placed within two discourses – that of therapy and that of community – and has almost exclusively focused on the first. In so doing, it has been restricted within a medical or pseudo-medical conceptual framework. In an appeal to re-frame the discussion about the therapeutic community in relation to its forgotten discourse reference is principally made to the work of the French psychoanalyst Jacques Lacan and to two of his sources – Heidegger and Socrates – and more specifically to Lacan’s notion of lack which is contrasted to modernity’s trope of expectation which corresponds to the Imaginary phallus.     

Some psychoanalytic and philosophical reflections on the signification of residence in the therapeutic care of people with schizophrenia

Last year saw the 20th anniversary of the Wagner report Residential care: A positive choice. The report tried to shift the emphasis away from the view that residential care is the last resort and to value its role as a vital part of community care. However, over the last few years there has been a move away from residential care for people suffering from mental ill-health. The rationale for this shift has been the prevailing idea that it is better to treat people in their own homes. Although this is to a large extent driven by financial constraints on the part of health and social service commissioners, running parallel is the development of policy informed by ideas of normalization, anti-stigma and the increasing drive to empower service users, and diminish the authoritarian relationship that professionals have with them. While much of this is commendable, there has been very little serious thinking about the meaning of residence or dwelling in relation to care and treatment. This has resulted in the ensuing ideological shift often amounting to little more than a fashionable mantra. In this paper the author discusses the meaning of residence and its relation to care, with reference to the work of Lacan and Heidegger, in an attempt to re-situate the debate about the therapeutic potential of residential care at a more fundamental level.     

Cue use by foals (Equus caballus) in a discrimination learning task

Discrimination learning studies suggest that horses learn more easily using spatial than visible object-specific (OS) cues. However, spatial cues have generally confounded intra-array, distal and/or egocentric spatial information. It is also unclear whether conflicting cues compete for association or are redundantly encoded, and furthermore, the influence of prior experiences or training has not been quantified so far. We examined the effect of cue modality on unweaned foals’ performance in a discrimination learning task. After a pilot study confirmed that horses could perform the required OS cue discrimination, nine foals learnt to find food in one of three covered buckets, in any of four positions within a test arena. In Stage 1 the rewarded bucket was signified both by OS cues (pattern) and by relative spatial cues (position). On reaching criterion, cues were separated and foals had to ignore the inappropriate cue (Stage 2). Foals assigned to follow spatial cues (n = 5) completed Stage 2 faster than foals for whom OS cues remained consistent (n = 4). Spatial group foals all reached criterion without delay; no foal in the OS group reached criterion within the testing period. OS group foals initially persisted in responding to the previously correct position, adopting spatially-based strategies when this proved unsuccessful. The findings show for the first time that, even in the absence of distal spatial information, intra-array spatial cues were more salient than OS cues for foals in a food-finding task and learning appeared rather inflexible.     

Comparing Self-differentiation and Psychological Well-being between Korean and European American Students

This study examined cross-cultural differences in the relationship of self-differentiation with self-esteem and depressed mood, two indices of psychological well-being. Participants were 427 Korean and 375 European American college students. The main findings were that the levels of all components of self-differentiation were greater for European Americans than for Koreans; self-differentiation was associated with psychological well-being more strongly in American samples than in Korean counterparts; and “I position” was the most powerful predictor on self-esteem in both groups. Results suggest that differentiation is a meaningful construct for understanding psychological adjustment of college students in collectivistic Korean society.This research was supported by the Chonbuk National University funds for overseas research, 2004.     

No evidence for ethnic and racial bias in the Tryout Edition of the Merrill-Palmer Scale-Revised

This research examined a revised version of the Merrill-Palmer Scale, a test of childhood development, to assess the cultural validity of items, i.e., Differential Item Functioning. Archival data were used to determine the Differential Item Functioning of items for 245 African-American, Euro-American, and Hispanic children, ages 3-6 years. Subjects were gathered from all four regions of the United States. Potential bias was examined through the use of partial correlations. Statistical analyses suggest that the Tryout Edition of the Merrill-Palmer Scale-Revised was not systematically biased toward any of the three racial groups examined.     

Dual-goal facilitation in Wason's 2-4-6 task: what mediates successful rule discovery?

The standard 2-4-6 task requires discovery of a single rule and produces success rates of about 20%, whereas the dual-goal (DG) version requests discovery of two complementary rules and elevates success to over 60%. The experiment examined two explanations of DG superiority: Evans' (1989) positivity-bias account, and Wharton, Cheng, and Wickens' (1993) goal-complementarity theory. Two DG conditions were employed that varied the linguistic labelling of rules (either positively labelled Dax vs. Med, or mixed-valence “fits” vs. “does not fit”). Solution-success results supported the goal-complementarity theory since facilitation arose in both DG conditions relative to single-goal tasks, irrespective of the linguistic labelling of hypotheses. DG instructions also altered quantitative and qualitative aspects of hypothesis-testing behaviour, and analyses revealed the novel result that the production of at least a single descending triple mediates between DG instructions and task success. We propose that the identification of an appropriate contrast class that delimits the scope of complementary rules may be facilitated through the generation of a descending instance. Overall, our findings can best be accommodated by Oaksford and Chater's (1994) iterative counterfactual model of hypotheses testing, which can readily subsume key elements of the goal-complementarity theory.     

Crowded and sparse domains in object recognition: consequences for categorization and naming

Some models of object recognition propose that items from structurally crowded categories (e.g., living things) permit faster access to superordinate semantic information than structurally dissimilar categories (e.g., nonliving things), but slower access to individual object information when naming items. We present four experiments that utilize the same matched stimuli: two examine superordinate categorization and two examine picture naming. Experiments 1 and 2 required participants to sort pictures into their appropriate superordinate categories and both revealed faster categorization for living than nonliving things. Nonetheless, the living thing superiority disappeared when the atypical categories of body parts and musical instruments were excluded. Experiment 3 examined naming latency and found no difference between living and nonliving things. This finding was replicated in Experiment 4 where the same items were presented in different formats (e.g., color and line-drawn versions). Taken as a whole, these experiments show that the ease with which people categorize items maps strongly onto the ease with which they name them.     

Category-specificity can emerge from bottom-up visual characteristics: evidence from a modular neural network

The role of bottom-up visual processes in category-specific object recognition has been largely unexplored. We examined the role of low-level visual characteristics in category specific recognition using a modular neural network comprising both unsupervised and supervised components. One hundred standardised pictures from ten different categories (five living and five nonliving, including body parts and musical instruments) were presented to a Kohonen self-organising map (SOM) which re-represents the visual stimuli by clustering them within a smaller number of dimensions. The SOM representations were then used to train an attractor network to learn the superordinate category of each item. The ease with which the model acquired the category mappings was investigated with respect to emerging category effects. We found that the superordinates could be separated by very low-level visual factors (as extracted by the SOM). The model also accounted for the well documented atypicality of body parts and musical instrument superordinates. The model has clear relevance to human object recognition since the model was quicker to learn more typical category exemplars and finally the model also accounted for more than 20% of the naming variance in a sample of 57 brain injured subjects. We conclude that purely bottom-up visual characteristics can explain some important features of category-specific phenomena.     

A systematic investigation of same and cross modality priming using written and spoken responses

Effects of presentation modality and response format were investigated using visual and auditory versions of the word stem completion task. Study presentation conditions (visual, auditory, non-studied) were manipulated within participants, while test conditions (visual/written, visual/spoken, auditory/written, auditory/spoken, recall-only) were manipulated between participants. Results showed evidence for same modality and cross modality priming on all four word stem completion tasks. Words from the visual study list led to comparable levels of priming across all test conditions. In contrast, words from the auditory study list led to relatively low levels of priming in the visual/written test condition and high levels of priming in the auditory/spoken test condition. Response format was found to influence priming performance following auditory study in particular. The findings confirm and extend previous research and suggest that, for implicit memory studies that require auditory presentation, it may be especially beneficial to use spoken rather than written responses.     

Investigating visual knowledge in dementia of the Alzheimer type (DAT): evidence for a structured organization

Given that certain types of semantic dysfunction in DAT have been attributed to difficulties in accessing visual knowledge, the issues of integrity of access to, and format of storage, within the "visual store" are particularly important. In these experiments, we tested 10 DAT patients and matched controls on the reality decision and part-whole matching tasks. Visual knowledge was found to be significantly impaired in the DAT group. Moreover, DAT patients displayed disproportionate deficits in accessing visual knowledge of items from nonliving categories. Results are interpreted within a framework of differential hierarchical access to visual representations of perceptually similar and perceptually distinct categories of items.
