Instigation to aggress and escalation of aggression examined from a personological perspective: The role of irritability and of emotional susceptibility

Two studies were conducted using Buss hostility machine paradigm to investigate the role of individual differences in irritability and emotional susceptibility on the instigation to aggress by a self-esteem lowering manipulation and on the hypothesized escalation of aggression over trials. The role of sex was also examined. In the first study, 60 highly irritable and 60 low irritable subjects were given the opportunity to deliver electric shocks to an experimental confederate, half after being provoked by a negative judgement on their performance in a learning task, half without such an experience. Each group of subjects was divided equally between males and females. It was found that highly irritable subjects, both males and females, delivered higher shocks after provocation than low irritable subjects under similar circumstances. An upward drift of shock level over trials was found only in provoked males and only in highly irritable females. In the second study, 60 highly emotionally susceptible and 60 low emotionally susceptible males and females were given the opportunity to deliver electric shocks to an experimental confederate, half after experiencing provocation, half without such an experience. It was found that provoked subjects delivered higher shocks than unprovoked subjects and that highly emotionally susceptible subjects delivered higher shocks than low emotionally susceptible subjects. Whereas an upward drift of shock levels over trials was found only in provoked males, the same effect was found in females, whether provoked or not. These findings are discussed in terms of the importance of stable personality characteristics that may mediate aggressive response.     

Face detection in complex visual displays: an eye-tracking study with 3- and 6-month-old infants and adults

The ability to detect and prefer a face when embedded in complex visual displays was investigated in 3- and 6-month-old infants, as well as in adults, through a modified version of the visual search paradigm and the recording of eye movements. Participants (N=43) were shown 32 visual displays that comprised a target face among 3 or 5 heterogeneous objects as distractors. Results demonstrated that faces captured and maintained adults' and 6-month-olds' attention, but not 3-month-olds' attention. Overall, the current study contributes to knowledge of the capacity of social stimuli to attract and maintain visual attention over other complex objects in young infants as well as in adults.     

Covert reading of letters in a case of global alexia

This study describes the case of a global alexic patient with a severe reading deficit affecting words, letters and Arabic numbers, following a left posterior lesion. The patient (VA) could not match spoken letters to their graphic form. A preserved ability to recognize shape and canonical orientation of letters indicates intact access to the representation of letters and numbers as visual objects. A relatively preserved ability to match lowercase to uppercase letters suggests partially spared access to abstract letter identities independently of their visual forms. The patient was also unable to match spoken letters and numbers to their visual form, indicating that she could not access the graphemic representations of letters from their phonological representations. This pattern of performance suggests that the link between graphemic and phonological representations is disrupted in this patient. We hypothesize that VA’ residual reading abilities are supported by the right hemisphere.     

Reducing Competitive Victimhood in Kosovo: The Role of Extended Contact and Common Ingroup Identity

During intractable conflicts, “competitive victimhood” refers to the subjective belief that one's own ingroup has suffered more than the outgroup. Although competitive victimhood is considered an important inhibitor of reconciliation processes, no research has attempted to examine ways of reducing it. The present study aims to fill this gap. Kosovar Albanians students (N = 170) were asked to report their perception of ingroup and outgroup victimhood during the protracted violence between Serbs and Albanians in Kosovo. Our findings revealed that frequent and high‐quality extended contact with outgroup members and identification with a common ingroup reduced competitive victimhood. The effects of extended contact and common ingroup identification were fully mediated by increased perspective taking and trust toward the outgroup, and by decreased outgroup infrahumanization. The implications of these results for restoring fractured intergroup relations are discussed.     

Selective impairment of living things and musical instruments on a verbal 'Semantic Knowledge Questionnaire' in a case of apperceptive visual agnosia

Semantic memory was investigated in a patient (MR) affected by a severe apperceptive visual agnosia, due to an ischemic cerebral lesion, bilaterally affecting the infero-mesial parts of the temporo-occipital cortices. The study was made by means of a Semantic Knowledge Questionnaire (Laiacona, Barbarotto, Trivelli, & Capitani, 1993), which takes separately into account four categories of living beings (animals, fruits, vegetables and body parts) and of artefacts (furniture, tools, vehicles and musical instruments), does not require a visual analysis and allows to distinguish errors concerning super-ordinate categorization, perceptual features and functional/encyclopedic knowledge. When the total number of errors obtained on all the categories of living and non-living beings was considered, a non-significant trend toward a higher number of errors in living stimuli was observed. This difference, however, became significant when body parts and musical instruments were excluded from the analysis. Furthermore, the number of errors obtained on the musical instruments was similar to that obtained on the living categories of animals, fruits and vegetables and significantly higher of that obtained in the other artefact categories. This difference was still significant when familiarity, frequency of use and prototypicality of each stimulus entered into a logistic regression analysis. On the other hand, a separate analysis of errors obtained on questions exploring super-ordinate categorization, perceptual features and functional/encyclopedic attributes showed that the differences between living and non-living stimuli and between musical instruments and other artefact categories were mainly due to errors obtained on questions exploring perceptual features. All these data are at variance with the 'domains of knowledge' hypothesis', which assumes that the breakdown of different categories of living and non-living things respects the distinction between biological entities and artefacts and support the models assuming that 'category-specific semantic disorders' are the by-product of the differential weighting that visual-perceptual and functional (or action-related) attributes have in the construction of different biological and artefacts categories.     

Eye movements and bisection behavior in spatial neglect syndrome: representational biases induced by the segment length and spatial dislocation of the stimulus

The present study explored behavioral and eye-movement measures in unilateral neglect patients in response to online bisection task (unfilled gap line). Two different tasks supported the bisection performance, a pointing and a grasping strategy. It was explored whether these different strategies may influence subjects' behavioral and eye-movement measures in response to different segment features: segment length (from shorter to longer) and segment spatial dislocation (from right to left spatial location). Consistent spatial biases were found for both bisection responses, fixation count, and duration, as well as for the first fixation count in case of pointing task. An "extreme-left" gradient effect was suggested and discussed, with patients' behavioral and eye measures more impaired. On the contrary, the patients' performance overlaps with the controls' one in case a grasping task. The direct link of visual pointing and grasping strategy, respectively, with the two cortical ventral and dorsal pathways was adduced to explain our results.

Perhaps There Is Accounting for Taste: Evaluating the Creativity of Products

Ratings on a creativity rating scale of students' designs of a hands-free mobile phone holder were compared for 2 sets of raters: experts (professional art teachers) and novices (visual art students). Reliabilities of total creativity scores were high for both groups, and interjudge consistency on total creativity scores, as well as on grades, was high among novices, but not as high among experts. Correlations between grades and total functional creativity scores within and across groups of raters (experts and novices) were highly significant. Scores on the scale resembled those yielded by assessments using grades and the scale did not yield better consistency among judges than conventional grades. Nonetheless, it provided a differentiated assessment of products that made it possible to explain the basis of experts' opinions and the reasons for disagreement, and to discuss the strengths and weaknesses of students' designs in a systematic and differentiated way.     

The Role of Gratitude in Breast Cancer: Its Relationships with Post-traumatic Growth, Psychological Well-Being and Distress

Despite the increasing number of studies documenting the positive effects of gratitude in coping with traumatic events and facilitating psychological well-being, none is addressed to patients with life-threatening illnesses such as cancer. The aims of this study are to examine the role of gratitude in a breast cancer sample and its correlations with post-traumatic growth, psychological well-being, and distress; and to compare patients reporting higher levels of gratitude (High Gratitude Individuals, HGI) versus those reporting lower levels (Low Gratitude Individuals, LGI). 67 breast cancer patients were assessed with: (1) Gratitude Questionnaire; (2) Post-traumatic Growth Inventory (PTGI); (3) Psychological Well-being Scales (PWBS) (4) Symptom Questionnaires (SQ); and were divided into: (1) High Gratitude Individuals—HGI (n = 27); (2) Low Gratitude Individuals—LGI (n = 40). Bivariate correlations between questionnaires and ANOVA between-group were calculated. Gratitude was significantly and positively correlated to all of PTGI scales, to PWBS positive relations, to SQ relaxation and contentment, and negatively related to anxiety, depression, and hostility-irritability. HGI and LGI reported significant differences on the PTGI and SQ dimensions, but not on PWB scales, with HGI displaying higher levels of PTGI, positive affect and lower symptomatology. Also in breast cancer patients gratitude is strongly associated to post-traumatic growth, reduced distress and increased positive emotions, but surprisingly not to psychological well-being. Since the majority of patients reported low gratitude levels, the results suggest the importance of developing interventions to clinically increase them also in oncology.
