Body-ownership for actively operated non-corporeal objects

Rubber-hand and virtual-hand illusions show that people can perceive body ownership for objects under suitable conditions. Bottom-up approaches assume that perceived ownership emerges from multisensory matching (e.g., between seen object and felt hand movements), whereas top-down approaches claim that novel body parts are integrated only if they resemble some part of a permanent internal body representation. We demonstrate that healthy adults perceive body ownership for a virtual balloon changing in size, and a virtual square changing in size or color, in synchrony with movements of their real hand. This finding is inconsistent with top-down approaches and amounts to an existence proof that non-corporeal events can be perceived as body parts if their changes are systematically related to one’s actions. It also implies that previous studies with passive-stimulation techniques might have underestimated the plasticity of body representations and put too much emphasis on the resemblance between viewed object and real hand.     

The countertransference impact of autistic defence in an otherwise neurotic patient

This paper investigates the question of why, in the psychoanalytic psychotherapy of a patient with encapsulated autistic pathology, the steady maintenance of a therapeutically neutral stance can be especially difficult. Transference and countertransference vicissitudes are examined. The author notices that the patient's intolerance of ‘opposites’ (cf. Tustin, 1986), combined with extreme antipathy to having that intolerance noticed, can elicit corresponding, and potentially destabilizing, countertransference reactions. These reactions comprise an unstable tension between co‐existing pressures towards fusion with, or expulsion of, the patient, their co‐existence under further pressure to remain unnoticed. Until perceived, this state of affairs risks collusion with the pressure either to merge with or to expel the patient, and compromises the capacity to notice the detail of the transference process and even to notice co‐existent positive and negative transference images. Detailed clinical illustration is given, including a session where it was difficult to notice the patient's experience of a couple as a combined object. The author finds these observations of bipolar countertransference tensions illuminated by Green's concepts of positive and negative narcissism and of the disobjectalizing function, and specifically accounted for by Ribas's theory of autism as radical drive defusion.     

无觉知条件下的客体注意效应

采用双矩形范式变式考察在对客体无觉知的条件下的客体注意效应,共包括两个实验：实验一考察对完整矩形客体无觉知的条件下能否出现客体注意效应,发现在完整矩形客体不可见的情况下依然出现了客体注意效应。实验二考察对虚拟矩形客体无觉知的情况下是否能够出现客体注意效应,发现在虚拟矩形客体不可见的情况下也能够出现客体注意效应。研究结果表明客体注意效应在无觉知条件下依然存在,为注意与觉知在功能上相互分离的观点提供了新的证据。     

汉语词汇产生中音、形、义三种信息激活的时间进程

采用图-词干扰范式和图片命名方法,探讨语音、语义、字形在汉语词汇产生中激活的时间进程与特点。选择与目标图片名称(如“羊”)具有同音(“阳”)、语义相联(“牛”)、字形相似(“丰”)或无关控制(“冷”)等四种关系的干扰字,依SOA条件呈现在将要被命名的图片上,发现图片命名时间受干扰字的影响：语义干扰效应存在于较早期的SOA(0ms)条件中,在较晚期SOA(150ms)时有很大的减弱;语音促进效应和字形促进效应同时强烈地存在于早期和晚期SOA。实验发现了词条选择(语义激活)和音位编码(语音提取)在激活时间上的重叠现象,与传统的独立两阶段模型的预期存在明显矛盾,倾向于支持交互作用理论的观点。     

Simulating single word processing in the classic aphasia syndromes based on the Wernicke-Lichtheim-Geschwind theory

The Wernicke-Lichtheim-Geschwind (WLG) theory of the neurobiological basis of language is of great historical importance, and it continues to exert a substantial influence on most contemporary theories of language in spite of its widely recognized limitations. Here, we suggest that neurobiologically grounded computational models based on the WLG theory can provide a deeper understanding of which of its features are plausible and where the theory fails. As a first step in this direction, we created a model of the interconnected left and right neocortical areas that are most relevant to the WLG theory, and used it to study visual-confrontation naming, auditory repetition, and auditory comprehension performance. No specific functionality is assigned a priori to model cortical regions, other than that implicitly present due to their locations in the cortical network and a higher learning rate in left hemisphere regions. Following learning, the model successfully simulates confrontation naming and word repetition, and acquires a unique internal representation in parietal regions for each named object. Simulated lesions to the language-dominant cortical regions produce patterns of single word processing impairment reminiscent of those postulated historically in the classic aphasia syndromes. These results indicate that WLG theory, instantiated as a simple interconnected network of model neocortical regions familiar to any neuropsychologist/neurologist, captures several fundamental "low-level" aspects of neurobiological word processing and their impairment in aphasia.     

Infants’ recognition of objects using canonical color

We explored infants’ ability to recognize the canonical colors of daily objects, including two color-specific objects (human face and fruit) and a non-color-specific object (flower), by using a preferential looking technique. A total of 58 infants between 5 and 8 months of age were tested with a stimulus composed of two color pictures of an object placed side by side: a correctly colored picture (e.g., red strawberry) and an inappropriately colored picture (e.g., green-blue strawberry). The results showed that, overall, the 6- to 8-month-olds showed preference for the correctly colored pictures for color-specific objects, whereas they did not show preference for the correctly colored pictures for the non-color-specific object. The 5-month-olds showed no significant preference for the correctly colored pictures for all object conditions. These findings imply that the recognition of canonical color for objects emerges at 6 months of age.     

Goodbye and farewell: Siegel vs. Feyerabend∗

The discussion between Searle and the Churchlands over whether or not symbolmanipulating computers generate semantics will be confronted both with the rulesceptical considerations of Kripke/Wittgenstein and with Wittgenstein's privatelanguage argument in order to show that the discussion focuses on the wrong place: meaning does not emerge in the brain. That a symbol means something should rather be conceived as a social fact, depending on a mutual imputation of linguistic competence of the participants of a linguistic practice to one another. The alternative picture will finally be applied to small children, animals, and computers as well.     

Phonological recoding,rapid automatized naming,and orthographic knowledge

Phonological recoding, orthographic knowledge, and rapid automatized naming (RAN) are three major contributors to word identification. However, the interrelations between these components remain somewhat unclear. The current analyses focus on how phonological recoding and alphanumeric versus non-alphanumeric RAN contribute to different components of orthographic knowledge (word specific vs. general). Results indicate that alphanumeric and non-alphanumeric RAN contribute to orthographic knowledge components differently. Alphanumeric RAN relates more to word-specific orthographic knowledge, whereas non-alphanumeric RAN relates more to general orthographic knowledge. Furthermore, phonological recoding is more closely related to word-specific orthographic knowledge than to general orthographic knowledge.     

Seduction,date rape,and aborted surrender

Abstract

This paper clarifies the dual-layered nature of the “demon lover complex,” with its background of both pre-Oedipal trauma and Oedipal-level desire. It draws on an object relations understanding of the unconscious and dissociated addiction to an internal demon object that has derivations in the personalities of the actual parents, and in the internalization of these parents. The dramatic case of early trauma compounded by adult date rape trauma serves to illustrate how a “developmental mourning process” in treatment can resolve such trauma. It also illustrates how reparation with the mother that partially heals pre-Oedipal trauma cannot immunize anyone against Oedipal-level attractions to a “demon lover” father, as represented in a displacement, resulting in victimized behavior, and in an aborted surrender to heterosexual desire. However, this victimization can be resolved, as seen in the clinical illustration, when the psychoanalyst has an understanding of the mourning process in developmental terms, working with a natural interaction between mourning and transference evolutions in treatment. The case also demonstrates the transitional object role of the psychoanalyst who is involved with the healing of pre-Oedipal trauma through mourning.     

Mirroring,imitation, identification: the sense of self in relation to the mother's internal world

The phenomenon of neonatal imitation, and the use of mutual imitation by mother and baby in the service of attunement, are considered in relation to psychoanalytic theories of mirroring, imitation and identification. Material from infant observation and from the treatment of two children on the autistic spectrum is discussed in terms of the suggestion that developmental imitation implies a perceived position of balance between the external baby and the mother's supposed internal occupant. This is seen as making possible introjective identification and assimilation, with the enrichment of the sense of identity, in contrast to the kind of imitation involving mimicry, in which adhesive or projective identification may be operative.
