Evaluation of Symptoms and Alexithymia in Psychiatric Patients: A Naturalistic Longitudinal Study in a Day Hospital

This study aimed to examine the effectiveness of a time-limited (10 months), combined individual and group treatment in a Day Hospital (DH) setting. Participants (N = 73) completed measures of general symptoms and alexithymia. We hypothesized improvements in these symptoms at the end of the overall therapeutic treatment. Results showed significant improvement in ability to identify and describe emotions and feelings, and in general symptoms. Differences in age and personality disorders were found at the end of the treatment: younger patients had less difficulty in identifying emotions, and psychotic patients have higher difficulty to describe feelings compared to patients with personality disorders. Furthermore, patients with schizophrenia had lower pathological symptoms compared to patients with mood disorders. This naturalistic longitudinal study demonstrates that DH treatments in group setting increase the patient‘s ability to symbolize and to connect their symptoms to thought and emotions.     

Mixing against culture vs mixing against nature: ontologization of prohibited interethnic relationships

In this paper, we develop the theory of ontologization: Social representations that prevent members of minority and majority groups who are living in contact with each other to mingle. The process of ontologization consists of separating some humans from their own species, and anchoring them in another environment, that of an animal, for example. We propose that underlying the famous slogan “equal but separate” is the social representation of interracial mixing as a “counter‐nature” phenomenon. It is predicted that a sexual relationship between people of different “races” leads to a greater degree of ontologization, and, as such, this miscegenation will be explained in terms of biologistic thinking, like an instinctive nature or atavistic animal impulse. An experiment (N = 360) features the case of a woman who, though already in a stable relationship, is unfaithful to her partner. In a 2×3 factor design, the ethnic‐national identity of this woman (in‐group: Spanish/Italian vs out‐group: Senegalese) and the ethnic‐national identity of her lovers (in‐group: Spanish/Italian vs out‐group: Rumanian vs out‐group: Senegalese) were manipulated. In general, results fit the hypothesis of ontologization in interracial conditions better, rather than the customary in‐group favouritism and/or out‐group discrimination bias. We then go on to discuss the way in which a biologistic way of thinking enables a differentiation at the human level, in terms of culture groups and nature groups, in “races,” so that an interracial sexual relationship is seen as evidence of a wild and irrepressible impulse, which stigmatizes the people involved in these relationships.

Preterm birth affects dorsal-stream functioning even after age 6

With increasing numbers of preterm infants surviving, the impact of preterm birth on later cognitive development presents a major interest. This study investigates the impact of preterm birth on later dorsal- and ventral-stream functioning. An atypical pattern of performance was found for preterm children relative to full-term controls, but in the dorsal-drawing task only. These findings suggest that the number of gestational weeks does affect dorsal-stream functioning, even after more than 6 years of favorable environmental conditions in healthy preterm children.     

The art of comforting

In the domain of social support, comforting is typically viewed as a form of help focused on providing relief from emotional distress. This specification is in our view insufficient to qualify comforting. Our work aims to provide a conceptual framework for comforting as a social process, by identifying its basic conditions while distinguishing it from other forms of social support such as help and advice. Special emphasis is placed on the role played by empathic sharing in comforting and being comforted. Then we focus on the comforter's perspective, addressing the typical difficulties implied by the comforting task, with special reference to those intrinsic to the task itself and the role played by empathic sharing in coping with such difficulties. We finally discuss the requirements for effective comforting, the view of comforting as a process of favoring the comfortees' reappraisal of their trouble, and the analogy between comforting and therapeutic help.     

Lightness constancy: Ratio invariance and luminance profile

The term simultaneous lightness constancy describes the capacity of the visual system to perceive equal reflecting surfaces as having the same lightness despite lying in different illumination fields. In some cases, however, a lightness constancy failure occurs; that is, equal reflecting surfaces appear different in lightness when differently illuminated. An open question is whether the luminance profile of the illumination edges affects simultaneous lightness constancy even when the ratio invariance property of the illumination edges is preserved. To explore this issue, we ran two experiments by using bipartite illumination displays. Both the luminance profile of an illumination edge and the luminance ratio amplitude between the illumination fields were manipulated. Results revealed that the simultaneous lightness constancy increases when the luminance profile of the illumination edge is gradual (rather than sharp) and homogeneous (rather than inhomogeneous), whereas it decreases when the luminance ratio between the illumination fields is enlarged. The results are interpreted according to the layer decomposition schema, stating that the visual system splits the luminance into perceived lightness and apparent illumination components. We suggest that illumination edges having gradual and homogeneous luminance profiles facilitate the luminance decomposition process, whereas wide luminance ratios impede it.     

The aggression test as a possible taxonomic tool in the Formica rufa group

The intra- and interspecific aggressive behavior of Formica polyctena, a species of the Formica rufa group, was analyzed and quantified both in the laboratory and in the field. This behavior was used as a potential taxonomic tool for gaining a better understanding of the phyletic relationships among the species within the group. No overt aggression was recorded toward members of the same species. To examine interspecific relationships, F. polyctena was first confronted with F. cunicularia, to ascertain its aggressiveness toward a distantly related species. All such encounters led immediately to overt and prolonged attacks with virtually no initial mutual inspection. This suggests that recognition of strangeness of the unrelated species is almost immediate in F. polyctena, as previously observed in F. lugubris and F. rufa toward the same antagonist. Subsequently, F. polyctena was contrasted with F. lugubris and F. rufa (also belonging to the F. rufa group) in order to compare these related species. Fierce attacks accompanied by all the elements of conflict behavior were observed in all encounters. Moreover, the degree of aggression in the field was higher than in laboratory-paired ants, possibly because of a territorial effect. These data and our previous and similar research indicate that the relationships between F. lugubris and F. rufa are closer than between these two species and F. polyctena. In considering different viewpoints on this problem, the validity of the aggression test is discussed and the opportunity to compare levels of aggressiveness among strictly sympatric samples of red wood ant species gathered from the same ecological environment are considered.     

Haptic estimates of discordant visual-haptic size vary developmentally.

In two size-conflict experiments, children viewed various squares through a reducing (1/2) lens while manually grasping them through a hand-concealing cloth. Then, using either vision or touch, they selected a match from a set of comparison squares. Forty 6-, 9-, and 12-year-olds participated in Experiment 1. Vision dominated the visual estimates of all three age groups; however, for the haptic estimates, the dominant modality varied developmentally: Vision dominated the 6-year-olds' haptic estimates, whereas neither modality dominated the 9-year-olds' haptic estimates, and touch dominated the 12-year-olds' haptic estimates. In Experiment 2, 24 six-year-olds were tested, as in Experiment 1; however, half of them were shown the size-distorting effects of the lens just prior to testing. Although this reduced the visual dominance of their haptic estimates, the effect was weak and short-lived. The haptic dominance seen in the data of the 12-year-olds was conspicuously absent.     

Why do women underperform under stereotype threat? Evidence for the role of negative thinking

This study investigated the role of negative thinking as a potential mediator of performance deficits under stereotype threat. After being assigned to a stereotype-threat or a no-threat condition, 60 female participants were asked to complete a difficult math task. Using the thought-listing technique, women under stereotype threat reported a higher number of negative thoughts specifically related to the test and to mathematics compared with women in the no-threat condition. Moreover, women under stereotype threat also showed a sharp decrease in performance that (a) was most pronounced in the second half of the test and (b) was mediated by the increase in negative thinking.     

Na+,K(+)-ATPase activity is reduced in hippocampus of rats submitted to an experimental model of depression: effect of chronic lithium treatment and possible involvement in learning deficits

This study was undertaken to verify the effects of chronic stress and lithium treatments on the hippocampal Na+,K(+)-ATPase activity of rats, as well as to investigate the effects of stress interruption and post-stress lithium treatment on this enzyme activity and on spatial memory. Two experiments were carried out; in the first experiment, adult male Wistar rats were divided into two groups: control and submitted to a chronic variate stress paradigm, and subdivided into treated or not with LiCl. After 40 days of treatment, rats were killed, and Na+,K(+)-ATPase activity was determined. In the second experiment, rats were stressed during 40 days, and their performance was evaluated in the Water Maze task. The stressed group was then subdivided into four groups, with continued or interrupted stress treatment and treated or not with lithium for 30 additional days. After a second evaluation of performance in the Water Maze, rats were killed and Na+,K(+)-ATPase activity was also measured. Results showed an impairment in Na+,K(+)-ATPase activity and in Water Maze performance of chronically stressed rats, which were prevented by lithium treatment and reversed by lithium treatment and by stress interruption. These results suggest that the modulation of Na+,K(+)-ATPase activity may be one of the mechanisms of action of lithium in the treatment of mood disorders.
