Responsiveness to estrous chemostimuli in male rats (Rattus norvegicus) of different ages

Previous findings indicate that Norway rats (Rattus norvegicus) respond differentially to estrous chemostimuli in early infancy and that adult male sexual responsiveness to such chemostimuli depends on infantile experience with suckling odors (Fillion & Blass, in press). The development of behavioral responsiveness to estrous chemostimuli in male rats from late infancy to adulthood was examined in this study. Preweanling, adolescent, and adult males were observed for 20 min in the presence of an anesthetized estrous or an anesthetized diestrous female. This was, for adolescent and adult subjects, the first heterosexual encounter since weaning. Rats in each age-group responded differentially according to female state, but in distinct, age-related ways. Preweanling spent more time investigating the female's body if she was estrous. Adults expressed the same affinity but by more focused investigation directed perivaginally. Adolescents showed no female-directed bias but groomed themselves more if the female was estrous. These data identify developmental continuities and discontinuities in male rat behavior toward sexually receptive females.     

Young children's attention to dyadic conversation as modified by sociometric status

Forty-eight American children, 12 popular and 12 rejected children from Grades 3 and 6, were paired with same-sex friends and nonfriends on an interactive task. Children were videotaped and their interactions judged for the amount and type of attention each child in the dyad gave to each other and the conversation. Main dependent measures included mutual engagements, acknowledgement of the partner, getting the attention of the partner, attention to the conversation, and social impact of the utterances. Both rejected and popular children attended to the conversation and the partner, but rejected children appeared to overattend in several ways. The interactions of rejected children and their matches involved more mutual engagements, conversational initiators, facilitators, terminators, and nonverbal attention-getting devices. Sex and developmental effects were also found.     

Spatial location judgments as a function of intention to learn, and mood state: an evaluation of an alleged automatic encoding operation

An assessment of the Hasher and Zacks (1979) conceptualization of the automatic nature of the acquisition of spatial location information was made in the context of manipulations of subjects' intention to learn and mood state. The Velten (1968) mood induction procedure was used to establish depressed and nondepressed subjects. Half of each group was then presented with a matrix of geometric forms under instructions to learn the location of the forms (intentional) or to evaluate the pleasantness of the array (incidental). Subsequent tests of spatial location performance found no differences as a function of subjects' mood state, but did find a strong effect for instructional condition. The superior performance of the intentional subjects raises questions about the automatic nature of the encoding of spatial location.     

Determinants of object choice in adulthood: a test case of object-relations theory

A clinical example of the effects of the absence of the father during the early childhood of a male analysand and its consequences for his later object choice is presented. This patient's biological father left the household when the patient was only a few months old, and his mother did not remarry until he was five years of age. Unconscious fantasies of the lost father, with whom the patient had no contact in reality, and longing for him organized the patient's drives and determined his self-identity as well as his later object choice. The patient developed both a positive and negative identification with the lost father. The identification was with a fantasy object not a real one. The case highlights the need to use a precise term in talking of the object, namely the mental representation of the object which may or may not be built up out of experiences with the real object.     

Superego formation, adolescent transformation, and the adult neurosis

The superego is heir to the Oedipus complex but has a much larger developmental legacy which includes preoedipal precursors and the influence of latency and adolescence. The superego continues to change in function and content throughout life, and radical transformation in adolescence may result in developmental discontinuity as well as core developmental continuity. A case is discussed in which adolescence was overlooked in previous analysis and in which adolescent superego modification had a major impact on the patient's character and his adult neurosis. The developmental significance of adolescence experienced under conditions of social isolation and rejection with forebodings of the Holocaust was unrecognized in sanctioned silence and shared analytic denial. These repeated earlier experiences of silent submission and stifled protest, and the silent suffering of the patient and his family, were an integral part of his humiliating and emasculating adolescent experiences. The intimidated adolescent, threatened from within and without, identified with the aggressor as well as with the victim. Identification with the aggressor and glorified victor contributed to a final adolescent structuralization of a punitive, sadistic superego and a rigidly perfectionistic ego ideal. As an adult, he tended to passive masochistic compliance with diminished self-esteem and unconscious self-denigration. He was prone to shame and guilt, self-criticism, and hidden hypercritical attitudes toward others. The adolescent internalization of aggression, intense castration anxiety, and pervasive narcissistic mortification led to retreat from resolution of revived oedipal conflict and to concomitant detrimental superego alteration. These issues were of major importance for analytic understanding and therapeutic progress.
