Visual categorization of natural stimuli by domestic dogs

One of the fundamental issues in the study of animal cognition concerns categorization. Although domestic dogs (Canis familiaris) are on the brink to become one of the model animals in animal psychology, their categorization abilities are unknown. This is probably largely due to the absence of an adequate method for testing dogs’ ability to discriminate between large sets of pictures in the absence of human cueing. Here we present a computer-automated touch-screen testing procedure, which enabled us to test visual discrimination in dogs while social cueing was ruled out. Using a simultaneous discrimination procedure, we first trained dogs (N = 4) to differentiate between a set of dog pictures (N = 40) and an equally large set of landscape pictures. All subjects learned to discriminate between the two sets and showed successful transfer to novel pictures. Interestingly, presentation of pictures providing contradictive information (novel dog pictures mounted on familiar landscape pictures) did not disrupt performance, which suggests that the dogs made use of a category-based response rule with classification being coupled to category-relevant features (of the dog) rather than to item-specific features (of the background). We conclude that dogs are able to classify photographs of natural stimuli by means of a perceptual response rule using a newly established touch-screen procedure.

The role of oxytocin in early mother-infant interactions: Variations in maternal affect attunement

The aim of the present research was to investigate the relationship between oxytocin and maternal affect attunement, as well as the role of affect attunement in the relationship between oxytocin and infant social engagement during early mother-infant interactions. Forty-three mother-infant dyads participated in the present study when infants were 4 months. They were observed during (1) a situation where no communication took place and (2) a natural interaction between mother and infant. During this procedure, three saliva samples from mothers and their infants were collected to determine their levels of oxytocin at different time points. Maternal affect attunement (maintaining attention, warm sensitivity) and infant interactive behaviors (gaze, positive, and negative affect) were coded during the natural interaction. Results indicated that overall maternal oxytocin functioning was negatively related to her warm sensitivity, while infant oxytocin reactivity together with maternal affect attunement were associated with infant positive social engagement with their mothers. Specifically, infant oxytocin reactivity was significantly related to their gazes at mother, but only for infants of highly attuned mothers. These results point to the complex role oxytocin plays in parent-infant interactions while emphasizing the need to analyze both overall oxytocin functioning as well as reactivity as different indices of human affiliative behavior.     

Control of pigeons' pecking by trace stimuli

In Experiment I, pigeons' pecking a white key was reinforced with grain when white was immediately preceded by a vertical white line on a green surround, but not by green alone. This procedure produced control of pecking by the line. Next, pecking white was reinforced after vertical line on green, but not after green alone or other orientations of the white line on green. The line-tilt dimension initially did not control pecking, a result that showed that interdimensional (line versus no line) training does not always result in dimensional control. Line-tilt control was eventually established but was accompanied by a decrease in interdimensional control. In Experiment II, interdimensional training, with or without a trace interval intervening between line on green or green alone and white, was followed by tests for line-tilt control. While interdimensional control was unaffected by the trace interval, line-tilt control tended to be less with the trace interval. This dissociation of interdimensional and dimensional control, as well as the failure of interdimensional training to produce dimensional control in Experiment I, suggests that the line stimulus is multidimensional.     

再认记忆测验中抑郁个体的心境一致性记忆研究

采用Ｊａｃｏｂｙ的加工分离程序,对再从记忆测验中外显记忆成分与内隐记忆成分的贡献进行分离,考察了抑郁个体的内隐记忆和外显记忆是否具有心境一致性记忆倾向。结果表明：抑郁个体的外显记忆具有心境一致性倾向,而内隐记忆不存在心境一致性倾向,表明心境一致性记忆需要精细加工机制的参与。另外发现,抑郁个体存在外显记忆缺损而没有出现内隐记忆缺损。最后就一些有待进一步研究的方面进行了讨论。     

Beyond Speech Lateralization: A Review of the Variability, Reliability, and Validity of the Intracarotid Amobarbital Procedure and Its Nonlanguage Uses in Epilepsy Surgery Candidates

While the intracarotid amobarbital procedure (IAP) was originally utilized to lateralize speech functions as an aid in the surgical treatment of epilepsy, additional uses for the IAP have emerged including: (1) the use of the IAP to predict post-surgical memory changes, including both global amnesia and smaller, yet significant, material-specific memory deficits; (2) the use of the IAP to provide confirmatory evidence of lateralization of seizure focus; and (3) the use of the IAP to predict post-surgical relief from seizures. While the literature on the IAP is extensive and growing, its utility is marred by the wide variability associated with the procedure itself from epilepsy center to center. This variability renders comparisons among IAP studies problematic and conclusions about IAP efficacy difficult. The variability associated with the amobarbital procedures, as well as the reliability and the validity of the IAP in its nonlanguage uses is reviewed here. A special emphasis is devoted to research conducted in the last decade. Also discussed is the future of the IAP including anticipated research directions.     

Dualism and its Importance for Medicine

Cartesian dualism has been viewed by medical theorists to be oneof the chief causes of a reductionist/mechanistic treatment ofthe patient. Although I aver that Cartesian dualism is one culprit for the misapprehension of the genuine treatment of patients in termsof both mind and body, I argue that interactive dualism whichstresses the interaction of mind and body is essential to treatpatients with dignity and compassion. Thus, adequate medical carethat is humanistic in nature is difficult (if not impossible)to achieve without physicians adhering to a dualistic frameworkin which the body and person is treated during illness.     

Determinants of capacious memory: a process-dissociation and experiential approach

The aim of this study is to delineate some important circumstances where exceptionally good memory performance, or capacious memory occurs. A further aim is to study memory processes involved in this memory phenomenon. In a first experiment, participants looked through two series of pictures differing in number and were evaluated in two-alternative forced-choice and yes-no recognition memory tasks combined in a process-dissociation procedure. Moreover, participants were asked to provide remember and know responses to tap recollective experience. The results as to forced-choice recognition task accuracy and according to process-dissociation procedure estimates were replicated in a second experiment with a more intrinsic contextual manipulation, and in a third, forgetting experiment. In addition to replicating previous findings, the results show (a) that capacious memory is associated with strong feelings of recollection; and (b) that familiarity (in terms of the process-dissociation framework) contributes to this phenomenon.     

The shadow of familiarity: a contributor to the intersubjective field

This paper examines the influence of familiarity on the progress of analysis. It is proposed that familiarity is a particular aspect of the intersubjective field which emerges over time and begins to shape and influence the behaviours, perceptions, thoughts, and feelings of the participants. It is also proposed that states of familiarity can have facilitative or defensive functions in an analytic relationship and that it is an influence co-created in the field. The experience of familiarity operates as background to our various foreground concerns in analytic work and therefore exists primarily as an implicit, rather than explicit, experience in analysis. Defensive familiarity often creates a feeling of relatedness that is subtly unrelated, a form of pseudo-intimacy. Parallels between defensive familiarity and related concepts are examined including defences against the unknown, role responsiveness, romantic love, the image of the stranger, and unformulated experience. This paper concludes with two case examples and a discussion of procedural knowledge in the implicit domain as an explanatory framework for the understanding of familiarity states in the analytic setting.
