Ontogenetic differences in conditioning of an aversion to a gustatory CS with a peripheral US

Rats 5, 10, or 15 days postnatal were given six pairings of an infused sucrose solution and footshock. Conditioned aversion to the sucrose solution was confirmed for the 5- and 10-day-old pups, but no conditioning was evident for the 15-day-old pups (Experiments 1 and 1A). In Experiment 2 the ventral portion of the rat's body was insulated from the shock source in order to isolate its effect on the feet and minimize visceral consequences of the shock. The sucrose-shock conditioning occurred as before. These results may have implications for the postnatal development of cue-consequence specificity, suggesting that such specificity may in part be learned. The present results also raise the possibility that sources of discomfort may be relatively undifferentiated in the perinatal rat.     

Semantic control of selective attention

Summary It is argued that at least three modes of information processing should be distinguished: (1) sensory preprocessing; (2) activation and inhibition of knowledge structures, which run parallel and are unlimited in terms of capacity; (3) activated knowledge structures are used to make behavioral decisions. Decision processes are assumed to be sequentially organized because at any moment only one unit of the activated knowledge can be taken into account. Selective attention mainly refers to the third mode of processing. In this paper, potential rules are investigated that may determine what part of the activated knowledge influences making decisions about behavior. An intuitively plausible speculation about a rule of this kind is that activated knowledge is taken into account in the order of its activation level. Certain phenomena in selective attention are related to the operation of the rule, and some data are presented that seem to favor the validity of the rule's operation in the processing of multi-element visual displays.     

Preference,Expectations, and Attributional Bias: Two Field Studies1

Two quasi-experiments were conducted to test the relationship among a perceiver's preference, expectations, and causal attributions for an event, when the outcome of the event ran for and counter to expectation and preference. Following the 1976 Superbowl, fans of Dallas and Pittsburgh and fans with no preference were asked to attribute causality for a series of game events, counterbalanced for (un)favorability for each team. Following the 1976 Presidential election, fans of Carter and Ford were asked to attribute causality for the election outcome and estimate its repeatability and mutability. Both studies revealed that fans exhibit a biased attributional pattern, offering more credit to their own side for their successes than to the opponents for their successes. Furthermore, fans see their side's successes as replicable and their side's failures as nonreplicable. The implications of the data patterns for real world manifestations of attributional bias are discussed.     

Reliability and validity of two widely-used worry questionnaires: self-report and self-peer convergence

The reliability and validity of the Penn State Worry Questionnaire (PSWQ) and the Worry Domains Questionnaire (WDQ) were examined with self-ratings from a non-clinical sample of 148 students in a test-retest design across four weeks. Ratings from three well-acquainted peers were also obtained. With internal consistencies and test-retest correlations of at least 0.85, the present study confirmed the high reliability of the questionnaires. Moreover, both measures demonstrated substantial convergent validity: Average agreement among peers was 0.42 (PSWQ) and 0.47 (WDQ) and aggregated self-peer agreement was 0.55 (PSWQ) and 0.49 (WDQ). Self-peer agreement was not biased by social desirability. These findings challenge views that worry is an unreliable and unobservable phenomenon.     

Finger width corrections in Fitts' law: implications for speed-accuracy research

This note points out that using the finger as a test probe in a Fitts task may lead to misleading results, because of the increased target tolerance resulting from the width of the finger pad. An experiment demonstrates the need to use a corrected target width when calculating the index of difficulty; without this correction, information processing rates are overestimated. An example is given of a developmental study in which the finger pad size changes with age. The resulting changes in the calculated rates of information processing are shown to be markedly different for the different age groups.     

Verlorenes Objekt, Trennung und Anerkennung

Zusammenfassung. Die Verarbeitung von Trennungserfahrungen ist für die Psychoanalyse ein zentrales Anliegen. Trennungserfahrungen spielen in verschiedenen analytischen Konzepten eine Rolle. Zun?chst mu? daher gekl?rt werden, welche verschiedenen Dimensionen des Themas „Trennung” in der psychoanalytischen Theorie ausgearbeitet worden sind. Da? Trennungen verarbeitet werden k?nnen, ist an bestimmte Voraussetzungen geknüpft. Die Folgen von Trennungserfahrungen sind v.a. aus einer intrapsychischen Perspektive beschrieben worden. Diese Betrachtungsweise mu? durch eine intersubjektive erg?nzt werden. Klinische Konzepte früher Trennungspathologien und die neuere S?uglingsforschung weisen auf die Bedeutung der intersubjektiven Perspektive für die Psychoanalyse hin. Intrapsychische und intersubjektive Perspektive schlie?en einander nicht aus, sondern verschr?nken sich miteinander. Wesentlich für dieses Wechselspiel ist der Begriff der Anerkennung, der in Anlehnung an Benjamin eingeführt wird. Er ist hilfreich, um die ethischen Implikationen der psychoanalytischen Trennungsmodelle zu bedenken.

The lost object, separation and recognition. About the foundation of psychoanalytic therapy and psychoanalytic ethics concerning the experience of separation

Summary. There exists not only one psychoanalytic concept of ”separation”. Instead, it covers a wide range of psychoanalytic constructs, such as separation in Mahler’s terms, object loss, castration, the Lacanian model of psychic representation and so forth. The first aim of the present paper is to clarify the various concepts. As will be shown, most psychoanalytic concepts focus on the intrapsychic dimension of separation processes. Nevertheless, the working through of separation experiences is bound to intersubjective experiences as can be shown in reference to the clinical concepts on very early interpersonal pathology and to the contemporary research on infantile development. The intersubjective and intrapsychic perspectives do not contradict, but supplement each other. J. Benjamin has introduced the term ”recognition” into the psychoanalytic debate. Recognition is a major link between the two perspectives. It is helpful to outline the ethical consequences that can be drawn from the psychoanalytic concepts on ”separations”.
