Young infants' expectations about hidden objects

Infants aged 3-5 months (mean of approximately 4 months) were given a novel anticipatory looking task to test object permanence understanding. They were trained to expect an experimenter to retrieve an object from behind a transparent screen upon hearing a cue ("Doors up, here comes the hand"). The experimenter then hid the object behind one of two opaque screens and after either 2 or 8s gave the "doors up" cue. Infants looked to the correct location after the two-second delay, but not after the eight-second delay. This indicates a brief memory that the object is present behind the occluder. The study provides converging evidence that infants grasp object permanence by a young age. The novel anticipatory looking paradigm helps rule out counter-explanations applied to violation-of-expectation tasks.     

A secret agent? How infants learn about the identity of objects in a causal scene

Four experiments examined the role of correlations between dynamic and static parts on 12- to 16-month-olds' ability to learn the identity of agents and recipients in a simple causal event. Infants were habituated to events in which objects with a dynamic or static part acted as an agent or a recipient and then were tested with an event in which the part-causal role relations were switched. Experiment 1 revealed that 16-month-olds, but not 12-month-olds, associate a dynamic part with the role of agent and a static part with the role of recipient. Experiment 2 showed that 12- and 16-month-olds do not associate a static part with the role of agent or a dynamic part with the role of recipient. Experiment 3 demonstrated that 14-month-olds will learn the relations presented in Experiment 1 and Experiment 2. Experiment 4 revealed that 12-month-olds were able to discriminate the two geometric figures in the events. The results are discussed with respect to infants' developing ability to attend to correlations between dynamic and static cues and the mechanism underlying early object concept acquisition.     

Treating Hypochondriasis with Interpersonal Psychotherapy

The treatment of hypochondriacal patients can be conceptualized as taking one of three approaches. These typically address one of the following questions: 1) “Should the patient be preoccupied?” 2) “Why is the patient preoccupied?” 3) “What are the interpersonal consequences of being preoccupied?” Interpersonal Psychotherapy (IPT) is specifically designed to address the last of these questions. IPT focuses on understanding the patient’s real distress, exploring the patient’s maladaptive communications, and modifying those communications so that others are more able to meet the patient’s attachment needs. With a focus on communication in a time-limited frame, fostered by a strong collaborative relationship, IPT appears to be an effective method of reducing hypochondriacal behavior.     

Differences in the Timing of Implausibility Detection for Recipient and Instrument Prepositional Phrases

We conducted two word-by-word reading experiments to investigate the timing of implausibility detection for recipient and instrument prepositional phrases (PPs). These PPs differ in thematic role, relative frequency, and possibly in argument status. The results showed a difference in the timing of garden path effects such that the detection of implausible dative recipients (which are clearly arguments) was delayed relative to the detection of implausible instruments (which may not be arguments). They also demonstrated that commitments to syntactic structure were made at the preposition for both dative and instrument PPs. While these results refute delay models of parsing (e.g., Britt, 1994) and syntax-first accounts of PP-attachment (e.g., Frazier, 1978; Frazier & Clifton, 1996), they support constraint-based lexicalist models that enable verb bias and plausibility information to compete (Garnsey, Pearlmutter, Myers, & Lotocky, 1997).     

Category specificity in normal episodic learning: applications to object recognition and category-specific agnosia

Studies of patients with category-specific agnosia (CSA) have given rise to multiple theories of object recognition, most of which assume the existence of a stable, abstract semantic memory system. We applied an episodic view of memory to questions raised by CSA in a series of studies examining normal observers' recall of newly learned attributes of familiar objects. Subjects first learned to associate arbitrarily assigned colors or textures to objects in a training phase, and then attempted to report the newly learned attribute of each object in a recall task. Our subjects' pattern of recall errors was similar both quantitatively and qualitatively to the identification deficits among patients with CSA for biological objects. Furthermore, errors tended to reflect conceptually and structurally based confusions. We suggest that object identification involves recruitment and integration of information across distributed episodic memories and that this process is susceptible to interference from objects that are structurally similar and conceptually related.     

Syntactic priming of relative clause attachments: persistence of structural configuration in sentence production

Three sentence completion experiments will be reported in which participants had to generate German equivalents of "the servant of the actress who..." (NP-of-NP-RC) constructions. Target fragments (which were unconstrained as to whether the relative pronoun permitted high or low attachment) were preceded by constrained prime fragments, which were either structurally congruent with the targets (Experiments 1 and 2) or structurally incongruent with the targets (anaphoric adverbial clauses rather than relative clauses (RCs), Experiment 3). While the first two experiments established reliable repetition of RC attachments between primes and targets, Experiment 3 failed to obtain a significant priming effect, indicating that RC attachment priming is dependent on a syntactic overlap between primes and targets. The results suggest a tendency of language producers to retain hierarchical syntactic relations over consecutive trials. Current models of syntactic priming in production do not offer an explanatory mechanism for this kind of observation as they presently stand.     

Motor facilitation following action observation: a behavioural study in prehensile action

Previous research has shown that the observation of actions and the execution of actions activate common neural systems. More recently, we have presented data showing that action observation of prehension primes subsequent execution (Castiello, Lusher, Mari, Edwards, & Humphreys, 2002). In the current paper we examined action priming under conditions in which the size of the prime did not predict the size of the target (only 20% of trials were valid). We demonstrated reliable priming under these conditions, consistent with the effect occurring automatically. In addition, we show priming even when observers saw just the object rather than the object and a reaching action on the prime trial. We discuss the findings in relation to the role of mirror neurons and object affordances.     

The Space Between in Group Psychotherapy: Application of a Multidimensional Model of Relationship

An 8-dimensional model of interpersonal relatedness, derived from existing theories of relationship as well as a phenomenological study, is applied to understanding the space between people in group therapy. Relational development is conceptualized as parallel streams of growth along separate dimensions, which may involve stronger relational capacities on some dimensions and weaker and more problematic behavior on others. This model is used to reflect on the group therapy situation in terms of how people are trying to connect with one another. Examples are offered and suggestions made for how the group therapist might be alert to the manifestations of each dimension. The goal is for both patients and therapist to have an enlarged view of what people need from one another and how to go about receiving it.     

The Phenomenology of Homesickness in Boys

Homesickness is the distress or impairment caused by an actual or anticipated separation from home. It is characterized by acute longing and preoccupying thoughts of home and attachment objects. This study extended previous research on the phenomenology of childhood homesickness by assessing a sample of 316 boys, ages 8–16, who were spending 2 weeks at a single-sex residential summer camp. Some 18% of the children reported moderate or high levels of homesickness; 7% reported concomitant severe depressive and anxious symptoms. Homesickness intensity was negatively correlated with separation experience and age. It was most commonly associated with depressive symptoms and internalizing behavior problems. For severely homesick boys, intensity increased over time, decreasing just prior to their return home. Preseparation assessment suggested that severely homesick boys had elevated levels of homesickness and negative emotions months before arriving at camp. One-year follow-up data suggested that the intensity of severe homesickness decreased with age and experience. However, severely homesick boys were less likely than other boys to return to camp. The results demonstrate how brief separations can affect children's well-being and attitudes about separations. Severe homesickness is distinct from separation anxiety disorder, but has elements of this and other psychopathologies. Theories of negative emotion, attachment, and coping complement emerging theories of homesickness.     

The relevance of attachment theory to a contemporary Jungian view of the internal world: internal working models, implicit memory and internal objects

In this paper I examine the various meanings of the term 'internal object' and the differences between various theoretical models for the formation of internal objects. I suggest that the idea in attachment theory of 'internal working models' emphasizes the internal world as one consisting of unconscious internalized patterns of emotional relationships. The term 'internal object' lacks this clarity and the different meanings it carries within differing theoretical frameworks are a source of confusion. I describe the role implicit memory plays in the formation of 'internal working model's and suggest that these offer us an alternative explanation for unconscious fantasy and for object relationships to that of instinctual drives. This model is then brought to bear on contemporary Jungian concepts of the internal world, with a suggestion that, seen in this light, Jung's formulation of the concept of the complex has many features in common with the 'internal working model' of attachment theory.
