Matching and oddity relational learning by pigeons (<Emphasis Type="Italic">Columba livia</Emphasis>): transfer from color to shape

Relational learning, as opposed to perceptual learning, is based on the abstract properties of the stimuli. Although at present there is no doubt that pigeons are capable of relational behavior, this study aims to further disclose the conditions under which it occurs. Pigeons were trained in an outdoor cage on a matching-to-sample or an oddity-from-sample task, with colored cardboard stimuli presented horizontally. The apparatus involved three sliding lids on which the stimuli were drawn and which, when displaced, revealed the reinforcement. The lids were either adjacent to each other or somewhat separated. Training sessions involved two colors, and test sessions six different colors (same dimension test), or six different shapes (different dimension test). One group of birds trained under the ‘adjacent’ condition failed when tested with new stimuli, but succeeded in both dimension tests after training under the ‘separate’ condition. Two other groups of birds succeeded in all tests after training under the latter condition. These results show that depending on procedural details, pigeons are or are not able to transfer from one visual dimension to another, thus extending previous related findings.     

The body in the analytic session: focusing on the body-mind link

The author focuses on the importance of the body in the analysis of patients with a defect of thinking. In many cases this defect is not fully evident until concrete and bodily aspects begin to emerge in sessions. In the absence of awareness of the body, the patient's personality is deprived of the main source of emotional stimulus, and mental growth is consequently paralysed. Hence the body is considered the starting point of mental processes and a progressive source of experience requiring the exercise of responsibility and thought. To indicate the theoretical background to this essentially clinical paper, some hypotheses about the body-mind link are very briefly considered. Specific emphasis is given to the development of Freud-Klein-Bionian theories about this subject and to some of Ferrari 's recent proposals. The author discusses four clinical cases, emphasizing the encounter with the body in analysis and its integration in emotional and thinking processes. The analyst's function in such cases is conceived mainly as that of midwife for a dialogue between the analysand 's body and mind.     

Hierarchical Classes Modeling of Rating Data

Hierarchical classes (HICLAS) models constitute a distinct family of structural models for N-way N-mode data. All members of the family include N simultaneous and linked classifications of the elements of the N modes implied by the data; those classifications are organized in terms of hierarchical, if–then-type relations. Moreover, the models are accompanied by comprehensive, insightful graphical representations. Up to now, the hierarchical classes family has been limited to dichotomous or dichotomized data. In the present paper we propose a novel extension of the family to two-way two-mode rating data (HICLAS-R). The HICLAS-R model preserves the representation of simultaneous and linked classifications as well as of generalized if–then-type relations, and keeps being accompanied by a comprehensive graphical representation. It is shown to bear interesting relationships with classical real-valued two-way component analysis and with methods of optimal scaling.

Catalyzing the dialogue between the body and the mind in a psychotic analysand

The author presents the analysis of a 23-year-old, obese, psychotic man who was dominated by sensations and unable to work through the different levels of psychic elaboration. He could not discriminate between words and concrete objects or between the perceptual functions of sense organs and the oral-cannibalistic level of instinct. Following the working through of these inabilities, it became possible to understand the patient's use of sensation and to make him aware of his emotions and conflicts. The author's discussion of this material emphasizes the role of the body-mind conflict and how this can be confronted in the analytic relationship. Possible links with neuroscience are also indicated.     

A modal ontology of properties for quantum mechanics

Our purpose in this paper is to delineate an ontology for quantum mechanics that results adequate to the formalism of the theory. We will restrict our aim to the search of an ontology that expresses the conceptual content of the recently proposed modal-Hamiltonian interpretation, according to which the domain referred to by non-relativistic quantum mechanics is an ontology of properties. The usual strategy in the literature has been to focus on only one of the interpretive problems of the theory and to design an interpretation to solve it, leaving aside the remaining difficulties. On the contrary, our aim in the present work is to formulate a “global” solution, according to which different problems can be adequately tackled in terms of a single ontology populated of properties, in which systems are bundles of properties. In particular, we will conceive indistinguishability between bundles as a relation derived from indistinguishability between properties, and we will show that states, when operating on combinations of indistinguishable bundles, act as if they were symmetric with no need of a symmetrization postulate.     

Tie strength and family formation: Which personal relationships are influential?

On the basis of the analysis of qualitative interviews in Western Germany, it has been argued that personal relationships have a strong impact on individuals' family formation processes and childbearing intentions. Persons who influence individuals' childbearing choices were identified. Strong ties, such as among core family members (i.e., parents and siblings), are an important contributing factor, but the authors are also able to show that weak ties, such as those among colleagues and acquaintances, need to be considered when examining social influence on family formation processes. Apart from single network partners, influential groups of persons have been identified. Such groups serve as a comparative standard regarding the timing of having one's first child and subsequent children.     

Social support: main and moderating effects on the relation between financial stress and adjustment among college students with disabilities

Students with disabilities are underrepresented in 4-year colleges and universities in the United States and those that do attend are at an increased risk of performing poorly in these settings. These difficulties for college students with disabilities may be compounded by additional stress related to financial concerns. The current study was designed to investigate the effects of social support on the adjustment of college students with disabilities generally, and among college students experiencing financial stress specifically. Results indicated that two types of social support (total support and satisfaction with support) had positive effects on the post-secondary adjustment of college students with disabilities. Moreover, both forms of support moderated the effects of financial stress on some, but not all, indicators of adjustment. The implications of these findings for future research and practice are discussed.     

Direct and interactive effects of parent,friend and schoolmate drinking on alcohol use trajectories

Objective: This study considered the unique and interactive roles of social norms from parents, friends and schools in predicting developmental trajectories of adolescent drinking and intoxication.

Design and outcome measures: Using data from the National Longitudinal Study of Adolescent Health, which followed adolescents (N = 18,921) for 13 years, we used discrete mixture modelling to identify unique developmental trajectories of drinking and of intoxication. Next, multilevel multinomial regression models examined the role of alcohol-related social norms from parents, friends and schoolmates in the prediction of youths’ trajectory group membership.

Results: Results demonstrated that social norms from parents, friends and schoolmates that were favourable towards alcohol use uniquely predicted drinking and intoxication trajectory group membership. Interactions between social norms revealed that schoolmate drinking played an important moderating role, frequently augmenting social norms from parents and friends. The current findings suggest that social norms from multiple sources (parents, friends and schools) work both independently and interactively to predict longitudinal trajectories of adolescent alcohol use.

Conclusions: Results highlight the need to identify and understand social messages from multiple developmental contexts in efforts to reduce adolescent alcohol consumption and alcohol-related risk-taking.     

Flexibility of the Psychoanalytic Approach in the Treatment of a Suicidal Patient: Stubborn Silences as “Playing Dead”

The author presents the clinical case of a patient in his third analysis who seemed emotionless, did not feel alive, and complained of an uncontrollable urge to gamble, with disastrous financial results. His previous four-session-a-week “orthodox” analysis had left him prey to a sense of emptiness and to intense suicidal urges. He wanted only two weekly sessions, which became three after some analytic work. The author stresses the danger of rigidly following inflexible standards and the consequent activation of a pseudo-compliance in the analysand. A more slowly paced psychoanalysis should not be considered lower in the pecking order than “high-frequency” treatment, the author maintains: It requires great creative subjective involvement on the part of the analyst and close interaction in the context of the analytic couple. The author shows how this analysis involved a series of interactions in which the analyst was called upon to exercise a complex responsiveness, attuned in each instance to the patient's current needs. Finally he focuses on some clinical passages to show how the patient's internal theories represent a glaring assault on common sense and how death was not recognized perceptionally on a realistic level, but was instead replaced with acting out death against himself by keeping himself mentally dead and by suicidal urges.
