Intersensory functioning in bobwhite quail chicks: early sensory dominance.

Two sensory systems known to be important for the control of early filial behavior in precocial avian neonates are the auditory and visual modalities. This study examined the interaction between naturally occurring auditory and visual stimulation in the control of filial behavior in bobwhite quail (Colinus virginianus) during the first four days of postnatal development. Results revealed a hierarchy in the functional priority of the auditory and visual systems in the days immediately following hatchling. At one and two days of age, species identification in quail hatchlings was found to depend on the auditory component of maternal stimulation. Later in development (at three and four days of age), combined auditory-visual stimulation was necessary to control species-specific filial behavior. Even at these later stages of development, however, the auditory modality remained dominant over the visual in eliciting responsiveness to the maternal hen. These findings conform well to what is known about the neuroembryological development of the sensory systems, in that the auditory system of birds (and mammals) develops in advance of the visual system. This prenatal sequence of sensory system development appears to influence the nature of early postnatal perceptual preferences and serves to question several traditional assumptions regarding the imprinting process.

Art and drama: partners in therapy.

An art-drama therapy group for latency-age boys made possible the exploration of personal symbols and intense fantasies which resulted in a therapeutically powerful and productive experience. This paper describes the background, rationale, and dynamic process of this group. Multimodal expressive arts therapy is supported.

"Totem and Taboo" in a latency boy.

Against the background of Freud's "Totem and Taboo" the case of a seven-year-old boy is discusses, focusing on his identification with a cat. Guided by Freud's dialectic thinking and his discussion of the phenomena of patriarchy and matriarchy, one is led to contemplate the totemism of a matriarchally oriented boy. The attempt to understand this child's pathology is based upon the concept of the specificity of a developmental phase. In the light of anthropological data, clinical phenomena are evaluated ontogenetically, in analogy with the recapitulation hypothesis.

A verbal group technique for ego-disturbed children: action to words.

The evolution of latency groups began over three decades ago with the inception of the activity group. Through modification and a greater emphasis on verbalization this developed into the play therapy model. At that time it was generally felt that verbal techniques were too threatening for latency age youngsters and that ego-defective children could not make use of a group approach. More recently successful work has been reported with both verbally oriented groups and groups with severely disturbed children. After tracing these developments, this paper describes a verbal, nondirective, insight-oriented group technique for ego-defective children. This technique is derived from the dynamics of latency, the techniques of individual play therapy, and the model of more conventional group psychotherapy. Clinical vignettes are reported to clarify the technique and demonstrate its efficacy. Though this approach is both demanding for the therapist and socially provocative in general, we think the results reported here require serious consideration and further evaluation.

Theoretical implications in current views of masturbation in latency girls.

Current views of masturbation in latency girls are drawn from direct observation, clinical experience with children, and from recollections of adult women. Reports in the literature and from the author invite re-examination of Freud's original theory that latency girls turn away from clitoral masturbation and develop persistent penis envy as a necessary step in development toward mature femininity.

Latent inhibition of fear potentiated startle in rats.

Non-reinforced pre-exposure to a prospective conditioned stimulus impairs subsequent conditioning. This phenomenon is termed latent inhibition. In this report, we demonstrate latent inhibition in a classical conditioning procedure, the fear-potentiated startle reflex. Normally, the startle response is enhanced in the presence of a conditioned stimulus that has previously been paired with an aversive stimulus. We show that fear-potentiation of the startle response is significantly less pronounced in rats that have been repeatedly pre-exposed to a conditioned light stimulus. Similar to other procedures reported in the literature, the administration of the psychostimulant drug amphetamine (1.0 mg/kg) before pre-exposure and conditioning disrupts latent inhibition. A good deal is known about the neuronal mechanisms underlying the acquisition and expression of fear-potentiated startle, and therefore this new procedure could be a useful tool for investigating the neuronal basis of latent inhibition.

Identification and its vicissitudes as observed in children: a developmental approach.

In the last thirty-five years, theories derived from observational studies on normally developing infants and toddlers as well as on children with severe pathology have augmented Freud's original contribution to the theory of identification. Mahler's formulations, in particular, are used in this paper to demonstrate the importance for identification of the mutual interaction between mother (or caregiver) and even the very young infant, and to delineate the gradual process by which are achieved intrapsychic self and object-representations. The thread of identification is followed from earliest mirroring of the young infant to post-oedipal ego identifications. I present aspects of the treatment of a borderline adopted boy to demonstrate problems in identification which occurs in part because his two primary caregivers competed to such a degree for possession of him, each demanding loyalty to herself and to herself alone, that his identity and identifications were confused, in fact duplicated. This white child had as his alter-ego, really as part of his self-representation, a black half of the self, personified as a black boy whom he fantasized to be his twin.
