Consequences of brain tumour resection on emotion recognition

Emotion processing impairments are common in patients undergoing brain surgery for fronto-temporal tumour resection, with potential consequences on social interactions. However, evidence is controversial concerning side and site of lesions causing such deficits. This study investigates visual and auditory emotion recognition in brain tumour patients with the aim of clarifying which lesion sites are related to impairments in emotion processing from different modalities. Thirty-four patients were evaluated, before and after surgery, on facial expression and emotional prosody recognition; voxel-based lesion–symptom mapping (VLSM) analyses were performed on patients’ post-surgery MRI images. Results showed that patients’ performance decreased after surgery in both visual and auditory modalities, but, in general, recovered 3 months after surgery. In facial expression recognition, left brain-damaged patients showed greater post-surgery deterioration than right brain-damaged ones, whose performance specifically decreased for sadness and fear. VLSM analysis revealed two segregated areas in the left hemisphere accounting for post-surgery scores for happy (fronto-temporo-insular region) and surprised (middle frontal gyrus and inferior fronto-occipital fasciculus) facial expressions. Our findings demonstrate that surgical removal of tumours in the fronto-temporal region produces impairment in facial emotion recognition with an overall recovery at 3 months, suggesting a partially different representation of positive and negative emotions in the left and right hemispheres for visually – but not auditory – presented emotions; moreover, we show that deficits in specific expression recognition are associated with discrete lesion locations.     

Envy and us

Within emotion theory, envy is generally portrayed as an antisocial emotion because the relation between the envier and the rival is thought to be purely antagonistic. This paper resists this view by arguing that envy presupposes a sense of us. First, we claim that hostile envy is triggered by the envier's sense of impotence combined with her perception that an equality principle has been violated. Second, we introduce the notion of “hetero‐induced self‐conscious emotions” by focusing on the paradigmatic cases of being ashamed or proud of somebody else. We describe envy as a hetero‐induced self‐conscious emotion by arguing (a) that the impotence felt by the subject grounds the emotion's self‐reflexivity and (b) that the rival impacts the subject's self‐assessment because the rival is framed by the subject as an in‐group member. Finally, we elaborate on the asset at stake in envy. We contend that this is esteem recognition: The envier covets the esteem that her reference group accords to the rival. Because, in envy, the subject conceives of herself as member of a group to which the other is also understood to belong, we conclude that envy is a social emotion insofar as it presupposes a sense of us.     

Introducing the concept of neurobiological foundation of Rorschach responses using the example of Oral Dependent Language

We introduce the concept of “neurobiological foundation” of Rorschach interpretations as an extension of the concept of behavioral representation as a foundation for interpretation of R‐PAS variables. Here, we propose that if there is a parallelism between the mental, verbal and perceptual behaviors occurring within the microcosm of the Rorschach task and those occurring in the external environment [behavioral foundation], then the same brain regions engaged by the test‐taker when producing of a given code, should be engaged also when reproducing, in the external environment, the same psychological processes underlying that specific Rorschach code [neurobiological foundation]. To investigate this concept, we used archival, fMRI data and tested whether producing Oral Dependency Language (ODL) responses would associate with increased activation in brain regions associated with dependency‐related, psychological processes. Results from a sample of 21 non‐clinical volunteers partially confirmed our hypothesis, providing some support to the neurobiological foundation of the ODL code.     

Assessing human reorientation ability inside virtual reality environments: the effects of retention interval and landmark characteristics

The purpose of the present study was to assess the navigational behaviour of adult humans following a disorientation procedure that perturbed their egocentric frame of reference. The assessment was carried out in a virtual reality (VR) environment by manipulating the disorientation procedure, the retention interval, the relative positions of target and landmark. The results of experiment I demonstrated that adding a physical rotation to a virtual disorientation procedure did not yield an additional decrease in searching performance. The results of experiment II showed that shortening the delay between study and test phase decreased the errors more markedly for geometric than landmark ones. An orientation specificity effect due to the manipulation of the relative position between target and landmark was discussed across the experiments. In conclusion, VR seemed to be a valuable method for studying human reorientation. Moreover, the virtual experimental setting involved here promoted knowledge of the relationship between working memory and spatial reorientation paradigm.     

A challenging intervention with maternal anxiety: Babies requiring surgical correction of a congenital anomaly after missed prenatal diagnosis

The objective of this study is to assess the impact on maternal anxiety of a short‐term intervention in a particularly stressful situation, such as a surgical anomaly diagnosed only at birth after repeated negative prenatal ultrasounds. The patients were 30 mothers of babies requiring surgical correction of a congenital anomaly who were randomly assigned to an intervention (N = 16) or control (N = 14) group. The intervention group received standard care plus short‐term intervention that included weekly meetings with the psychologist and weekly team meetings. The control group received only standard care available on the Neonatal Surgery Unit. The main outcome measure was maternal anxiety levels, assessed at birth and on discharge with the Spielberger State–Trait Anxiety Inventory (STAI–S). Statistical comparisons were made, and no significant differences were found at birth in the STAI–S scores of the two groups. At discharge, the intervention group exhibited a much lower STAI–S score than the group without short‐term intervention. The authors concluded that psychological counseling for parents of newborn babies has been shown to be helpful. However, the impact of such assistance was shown to be particularly beneficial for parents facing the emotional stress of their children requiring unexpected surgical corrections of congenital anomalies at birth. Therefore, the presence of a psychologist, as part of the standard care of newborns requiring surgical correction, is recommended. ©2003 Michigan Association for Infant Mental Health.     

Parental styles in prospective fathers: A research carried out using a semistructured interview during pregnancy

Recent reviews on research into fathers consistently have drawn attention to the increased knowledge and thinking of the multifaceted, complex, and changing nature of fathers' role. Paternal involvement has been studied with reference to a number of variables, including personality, attitudes, and family structure. The concept of “understanding mental states” and of mentalization and the notion and working definition of Reflective Self Function, as devised by Fonagy and colleagues, seem to have important implications for paternal and parental involvement, and for normal development of the infant–caretaker relationship. The aim of our research was to broaden current knowledge and thinking about fathering during pregnancy by investigating how 112 prospective fathers are involved in the transition to fatherhood and how they are able to reflect on their experience. Our aim was to identify parental styles according to May's concepts and to rate Reflective Self Function in The Clinical Interview for Parents During Pregnancy [Colloquio per Genitori in Gravidanza (CGG)]. The CGG is a semistructured clinical interview devised with the most recent psychoanalytic views on mental representations taken into account and is aimed at investigating feelings and attitudes toward the baby, the couple's inner and subjective world. Our results highlighted the complexity of paternal involvement in pregnancy and its relation with Reflective Self Function. Specific relations also were found between Reflective Self Function and the three styles of detachment/involvement identified by May. ©2004 Michigan Association for Infant Mental Health.     

Personality traits and endocrine response as possible asymmetry factors of agonistic outcome in karate athletes

Individual variations of plasma levels of hormones testosterone (T) and cortisol (C), before (pre) and after (post) Kumite (real fight) and Kata (ritualized fight) were measured in male karate athletes and analyzed in relation with the agonistic outcome (i.e. winning or losing the fight) and personality trait measures. T and C increased only during Kumite contest and pre‐ and post‐competition C levels were higher in losers than winners. Losers showed higher levels of harm avoidance and anxiety as well as lower level of novelty seeking than winners. Importantly, novelty seeking negatively correlates with pre C and the higher the level of risk assessment, emotionality and insecurity indexes the higher the pre C level. In conclusion, personality traits might be an important factor asymmetry between athletes influencing both the probability of winning or losing an agonistic interaction and the different anticipatory endocrine response to the incipient fight.

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.
