Enactments: an intersubjective perspective.

We offer a critique and synthesis of classical and interpersonal views of enactment. From an intersubjective standpoint, the study of enactment leads to a reconsideration of the nature of the psychoanalytic process. And enactment becomes virtually synonymous with the psychoanalytic process. Enactments are interactions of analysand and analyst with communicative and resistive meanings that lead to valuable insight and can constitute corrective emotional experiences. Enactments that are recognized and defined become valuable dramatizing moments that have condensing, clarifying, and intensifying effects upon consciousness. The inevitable participation by the analyst in enactment is compatible with appropriate analytic discipline. A case will demonstrate these points.     

A connectionist account of asymmetric category learning in early infancy

Young infants show unexplained asymmetries in the exclusivity of categories formed on the basis of visually presented stimuli. A connectionist model is described that shows similar exclusivity asymmetries when categorizing the same stimuli presented to infants. The asymmetries can be explained in terms of an associative learning mechanism, distributed internal representations, and the statistics of the feature distributions in the stimuli. The model was used to explore the robustness of this asymmetry. The model predicts that the asymmetry will persist when a category is acquired in the presence of mixed category exemplars. An experiment with 3-4-month-olds showed that asymmetric exclusivity persisted in the presence of mixed-exemplar familiarization, thereby confirming the model's prediction.     

Explanation-based learning in infancy

In explanation-based learning (EBL), domain knowledge is leveraged in order to learn general rules from few examples. An explanation is constructed for initial exemplars and is then generalized into a candidate rule that uses only the relevant features specified in the explanation; if the rule proves accurate for a few additional exemplars, it is adopted. EBL is thus highly efficient because it combines both analytic and empirical evidence. EBL has been proposed as one of the mechanisms that help infants acquire and revise their physical rules. To evaluate this proposal, 11- and 12-month-olds (n?=?260) were taught to replace their current support rule (that an object is stable when half or more of its bottom surface is supported) with a more sophisticated rule (that an object is stable when half or more of the entire object is supported). Infants saw teaching events in which asymmetrical objects were placed on a base, followed by static test displays involving a novel asymmetrical object and a novel base. When the teaching events were designed to facilitate EBL, infants learned the new rule with as few as two (12-month-olds) or three (11-month-olds) exemplars. When the teaching events were designed to impede EBL, however, infants failed to learn the rule. Together, these results demonstrate that even infants, with their limited knowledge about the world, benefit from the knowledge-based approach of EBL.     

Interventions in early infancy

Infants of high-risk pregnancies and deliveries may need early intervention to facilitate attachment both to and from their caregivers. Three early interventions are described: (1) giving high-risk pregnant women video feedback during prenatal ultrasound, which reduced maternal anxiety, obstetric complications, and fetal activity and improved neonatal outcome (increased weight gain, better performance on the Brazelton, and decreased irritability); (2) providing preterm neonates nonnutritive sucking opportunities to reduce stress during heelsticks and gavage feedings; and (3) providing preterm neonates and preterm cocaine-exposed neonates massage therapy, which facilitated weight gain and better performance on the Brazelton scale. Following improved neonatal behavior, infants would be expected to have better interactions with their caregivers.     

Unconscious perception and reverie: an intersubjective connection*

This paper discusses an intriguing topic for psychoanalysis: the concept of unconscious communication. Beginning with the concept of unconscious perception, it moves on to figurability and culminates with reverie. Auxiliary concepts, such as receptive unconscious, intersubjectivtiy, countertransferrence and empathy, are discussed in order to articulate the conceptual network on which theoretical arguments are based.     

Beyond doer and done to: an intersubjective view of thirdness

Analytic work based on the intersubjective view of two participating subjectivities requires discipline rooted in an orientation to the structural conditions of thirdness. The author proposes a theory that includes an early form of thirdness involving union experiences and accommodation, called the one in the third, as well as later moral and symbolic forms of thirdness that introduce differentiation, the third in the one. Clinically, the concept of a co-created or shared intersubjective thirdness helps to elucidate the breakdown into the twoness of complementarity in impasses and enactments and suggests how recognition is restored through surrender.     

Selective social learning in infancy: looking for mechanisms

Although there is mounting evidence that selective social learning begins in infancy, the psychological mechanisms underlying this ability are currently a controversial issue. The purpose of this study is to investigate whether theory of mind abilities and statistical learning skills are related to infants’ selective social learning. Seventy‐seven 18‐month‐olds were first exposed to a reliable or an unreliable speaker and then completed a word learning task, two theory of mind tasks, and a statistical learning task. If domain‐general abilities are linked to selective social learning, then infants who demonstrate superior performance on the statistical learning task should perform better on the selective learning task, that is, should be less likely to learn words from an unreliable speaker. Alternatively, if domain‐specific abilities are involved, then superior performance on theory of mind tasks should be related to selective learning performance. Findings revealed that, as expected, infants were more likely to learn a novel word from a reliable speaker. Importantly, infants who passed a theory of mind task assessing knowledge attribution were significantly less likely to learn a novel word from an unreliable speaker compared to infants who failed this task. No such effect was observed for the other tasks. These results suggest that infants who possess superior social‐cognitive abilities are more apt to reject an unreliable speaker as informant.

From object to subject: pastoral supervision as an intersubjective activity

The author sketches the development of psychoanalysis in terms of its trends from notions of objectivity to intersubjectivity and how this movement can inform contemporary pastoral supervision. The article argues that these same trends may be noted in the development of contemporary educational and theological theories.     

Visual statistical learning in infancy: evidence for a domain general learning mechanism

The rapidity with which infants come to understand language and events in their surroundings has prompted speculation concerning innate knowledge structures that guide language acquisition and object knowledge. Recently, however, evidence has emerged that by 8 months, infants can extract statistical patterns in auditory input that are based on transitional probabilities defining the sequencing of the input's components (Science 274 (1996) 1926). This finding suggests powerful learning mechanisms that are functional in infancy, and raises questions about the domain generality of such mechanisms. We habituated 2-, 5-, and 8-month-old infants to sequences of discrete visual stimuli whose ordering followed a statistically predictable pattern. The infants subsequently viewed the familiar pattern alternating with a novel sequence of identical stimulus components, and exhibited significantly greater interest in the novel sequence at all ages. These results provide support for the likelihood of domain general statistical learning in infancy, and imply that mechanisms designed to detect structure inherent in the environment may play an important role in cognitive development.     

Visual feature binding in early infancy

How does the developing brain of the human infant solve the feature-binding problem when visual stimuli consisting of multiple colored objects are presented? A habituation--dishabituation procedure revealed that 1-month-old infants have the ability to discriminate changes in the conjunction of a familiar shape and color in two objects. However, this good earlier performance was followed by poorer performance at 2 months of age. The performance improved again at 3 months of age. Detailed analysis of the oculomotor behaviors revealed that the age of 2 months was a period of drastic transition when the tendency to stay with the fixated objects disappeared and repetitive saccades between the two objects emerged. Our findings suggest that the ability to perceive conjunctions of features is available to infants very early, that the perceptual/neural basis at 1 and at 3 months of age may be fundamentally different, and that feature integration by vigorous eye movements or selective attention may be the key functional difference between the age groups.     

High-frequency VEP wavelets in early infancy: A preliminary study

The flash-evoked visual evoked potential (VEP) was recorded in 12 infants 0–12 weeks of age. Along with traditional low-frequency waves (1–35 Hz), high-frequency (50–100 Hz) wavelets were examined. No wavelets were apparent in records obtained from infants below 4 weeks of age, although the low-frequency waves were clearly present at all ages tested. Wavelets showed a steady increase in amplitude and a small decrease in implicit time across the time period studied. The changes in wavelet development can be interpreted as a reflection of the significant postnatal maturation of the primary visual system, particularly the maculo and visual cortex.     

Talking about talking: Interpersonal process recall as an intersubjective approach to research

Research methods are often marked by inequalities between researcher and researched, maintained through dominant discourses that structure expectations of research. This study considers how therapeutic skills such as reflexivity can help to develop alternative discourses, raise awareness and challenge inequalities in research. An approach to the qualitative analysis of research interviews using interpersonal process recall (IPR) is outlined. By focusing attention on the dialogue and enabling researcher and research participant to review and explore their interaction reflexively, IPR offers an opportunity to understand interviews as intersubjective events. It thus facilitates the collaborative identification of processes and narratives as key moments for further analysis and increases awareness of the potential blurring of genres between therapeutic and research conversations. The contribution of IPR to an intersubjective lens and greater equality in research interviewing is discussed. Potential implications for both research and therapy practices are suggested.     

A componential analysis of an early learning deficit in mathematics

This study was designed to assess strategy choice and information-processing differences in normal and mathematically disabled first and second grade children. Twenty-three normal and 29 learning disabled (LD) children solved 40 computer-presented simple addition problems. Strategies, and their associated solution times, used in problem solving were recorded on a trial-by-trial basis and each was classified in accordance with the distributions of associations model of strategy choices. Based on performance in a remedial education course, as indexed by achievement test scores, the LD sample was reclassified into a LD-improved group and an LD-no-change group. No substantive differences comparing the normal and LD-improved groups occurred in the distribution of strategy choices, strategy characteristics (e.g., error rates), or rate of information processing. The performance characteristics of the LD-no-change group, as compared to the two remaining groups, included frequent counting and memory retrieval errors, frequent use of an immature computational strategy, poor strategy choices, and a variable rate of information processing. These performance characteristics were discussed in terms of the strategy choice model and in terms of potential long-term memory and working memory capacity deficits. In addition, implications for remedial education in mathematics were discussed.     

Medical family therapy: an emerging arena for family therapy

This paper describes an important recent development in American family therapy. Medical family therapy uses a biopsychosocial systems model to work with families who have a member with a chronic illness or disability. The authors maintain that family therapy has tended to embrace the mind–body split and to view itself too narrowly as a mental health specialty. Medical family therapists work collaboratively with physicians and other health professionals to help families achieve a sense of agency and communion in facing some of the greatest challenges that life brings.     

Central and peripheral vision in early infancy

The size of the effective visual field during the first weeks of life is found to depend on two factors: It increases with age, but it contracts in the face of competition from ongoing activity such as fixation of a central stimulus or non-nutritive sucking.
