The positive effect of negative emotions in protracted conflict: The case of anger

Extant research has demonstrated the destructive role that anger plays in the context of intergroup conflict. Among other findings, it has been established that anger elevates public support for aggressive and violent actions towards the outgroup. This finding has been explained by the unique cognitive appraisals, emotional goal, and response tendencies associated with anger, typified by appraised relative strength and high control, motivation to correct perceived wrongdoings, and willingness to engage in risky behavior. In the current work we examine an innovative assumption, according to which the apparent destructive implications of anger are a result of situational range restriction—namely, that anger as a group emotion has been examined almost solely at the escalation stage of conflict. Instead, we propose that the same unique characteristics of anger can bring about constructive political attitudes and support for non-violent policies in the context of systematic efforts to de-escalate a protracted conflict.To test this hypothesis we conducted two studies in which we examined the relationship between anger and the willingness to engage in positive risk-taking and support non-violent policies in the context of political negotiations between adversaries. Results indicate a significant positive relationship, supporting the hypothesis that anger is not an exclusively militant emotion, and its effects are situationally dependent.     

The Isolation of Motivational, Motoric, and Schedule Effects on Operant Performance: A Modeling Approach

Dissociating motoric and motivational effects of pharmacological manipulations on operant behavior is a substantial challenge. To address this problem, we applied a response‐bout analysis to data from rats trained to lever press for sucrose on variable‐interval (VI) schedules of reinforcement. Motoric, motivational, and schedule factors (effort requirement, deprivation level, and schedule requirements, respectively) were manipulated. Bout analysis found that interresponse times (IRTs) were described by a mixture of two exponential distributions, one characterizing IRTs within response bouts, another characterizing intervals between bouts. Increasing effort requirement lengthened the shortest IRT (the refractory period between responses). Adding a ratio requirement increased the length and density of response bouts. Both manipulations also decreased the bout‐initiation rate. In contrast, food deprivation only increased the bout‐initiation rate. Changes in the distribution of IRTs over time showed that responses during extinction were also emitted in bouts, and that the decrease in response rate was primarily due to progressively longer intervals between bouts. Taken together, these results suggest that changes in the refractory period indicate motoric effects, whereas selective alterations in bout initiation rate indicate incentive‐motivational effects. These findings support the use of response‐bout analyses to identify the influence of pharmacological manipulations on processes underlying operant performance.     

Muscarinic receptors activity in the perirhinal cortex and hippocampus has differential involvement in the formation of recognition memory

In this work we probed the effects of post-trial infusions of the muscarinic receptor antagonist scopolamine on object recognition memory formation. Scopolamine was infused bilaterally immediately after the sample phase in the perirhinal cortex or dorsal hippocampus and animals were tested for short-term (90 min) or long-term (24 h) memory. Results showed that scopolamine impaired short-term memory when injected in either the perirhinal cortex or hippocampus. Nevertheless, scopolamine disrupted long-term memory when administrated in the perirhinal cortex but not when applied in the hippocampus. Long-term memory was unaffected when scopolamine was infused 160 min after the sample phase or 90 min before test phase. Our data indicate that short-term recognition memory requires muscarinic receptors signaling in both the perirhinal cortex and hippocampus, whereas long-term recognition memory depends on muscarinic receptors in the perirhinal cortex but not hippocampus. These results support a differential involvement of muscarinic activity in these two medial temporal lobe structures in the formation of recognition memory.     

Where Am I? A new case of developmental topographical disorientation

Recently, developmental topographical disorientation (DTD) was described (Bianchini et al., 2010, J Clin Exp Neuropsychol, 20, 807–27; Iaria & Barton, 2010, Exp Brain Res, 206, 189–96; Iaria, Bogod, Fox, & Barton, 2009, Neuropsychologia, 47, 30–40) as a navigational deficit in the absence of neurological or psychiatric disorders. Here, we reported the case of a healthy subject who presented this disorder. Dr. WAI was a 29‐year‐old right‐handed man with normal development and no clinical history of neurological or psychiatric diseases who was affected by a very pervasive topographical orientation and navigational disorder. A neuroradiological exam confirmed the absence of structural and anatomical alterations of the brain. Dr. WAI was submitted to an extensive neuropsychological examination and to a battery of tests specifically developed to assess developmental topographical disorder. Using this battery, we analysed Dr. WAI's acquisition of navigational information and re‐orientation processes. He showed severe DTD accompanied by deficits of different cognitive processes directly or indirectly involved in navigational skills. Dr. WAI showed a deficit in developing cognitive maps, already found in previous cases, plus difficulties in evaluating distances and computing metric environmental features. He represents a further confirmation of the existence of DTD suggesting dissociations within the disorder related to the level of development of the ability to build cognitive maps and the association of different imagery deficits. Dr. WAI can help in shedding some light on the mechanisms underlying lack of development of navigational skills.     

Toward a further understanding of assent

Arranging assent opportunities is an increasingly common strategy for involving clients in therapeutic decisions within behavior analysis. Recent behavior-analytic articles have helped create a basic behavioral definition and conceptualization of assent, but much more guidance is needed for practitioners and researchers interested in embedding assent into their practices. The purpose of this article is to advance the conceptualization and understanding of assent and assent practices by refining previous definitions and conceptualizations of assent and providing six essential considerations for embedding assent into practice. The six considerations consist of determining the applicability and feasibility of assent, assessing assent-related skills, arranging assent procedures and teaching assent-related skills, arranging fair choices, selecting opportunities to assess assent, and informally assessing assent. Following the discussion of the considerations for assent practices, we issue a call for specific topics of research on assent.     

Identification of risk factors for suffering fear of hypoglycemia in type 1 Diabetes Mellitus patients

Hypoglycemia is one of the main burdens for type I Diabetes Mellitus (DM I) patients. The consequences of hypoglycemia can be quite unpleasant due to the variety of disagreeable physical and psychological symptoms it triggers. The patient's previous experience with hypoglycemia episodes will condition his psychological reaction to future episodes, promoting behavioral modifications that associate with poor glycemic control and worse prognosis, and even with developing psychological disorders, leading to fear of hypoglycemia (FH). To be able to provide tailored prevention and treatment of patients with FH it is necessary to identify the risk factors in DM I patients. We developed and validated the FH‐15 scale, a novel instrument to assess FH, which showed good concurrent and predictive validity in DM I patients. In this work we aim to identify the risk factors for suffering FH by detecting DM I patients with FH using the FH‐15 scale and then analyzing the association of clinical and sociodemographic variables. We found that age, needing help to resolve an episode of hypoglycemia, and a perceived lack of social support are risk factors for suffering FH.     

Gender Differences in the Perception of Honour Killing in Individualist Versus Collectivistic Cultures: Comparison Between Italy and Turkey

Gender differences in the perception of honour killing were investigated in two countries, both traditionally considered honour cultures but with differing degrees of individualism and collectivism: Italy and Turkey. Ninety-six Turkish undergraduate students attending Istanbul University (40 % males, mean age?=?21.2 years) and 68 Italian undergraduate students attending Turin University (34 % males, mean age?=?24.6 years) filled in a questionnaire which assessed the perception of three honour killing scenarios (scenario 1: alleged adultery, scenario 2: adultery, scenario 3: adultery in flagrante delicto). The questionnaire measured the attribution of assailant and victim responsibility, the proposed punishment for the assailant, and the evaluation of the incidents as crimes. Results showed that regardless gender Turkish participants attributed more responsibility to the victim and less responsibility to the assailant, and proposed less severe punishments than the Italian participants. Moreover, Turkish men attributed less responsibility to the assailant and proposed less severe punishments than Turkish women. Finally, there was an interaction of gender by culture by scenario: Turkish women attributed less responsibility to the victim in the case of alleged adultery, compared to their male counterparts. These results are discussed in terms of the complex interaction between gender roles and the individualist versus collectivist social organization of Italy and Turkey, and the profound social changes that both countries have undergone in recent decades.     

Effectiveness of parent counselling in eating disorders

ABSTRACT

Eating Disorders (ED) are often severe illnesses entailing a heavy burden for families. Family therapy is recommended for young patients, but only a few studies have investigated therapeutic interventions with families tailored also to adult and longstanding patients. We recruited 87 families with daughters affected by an ED, aiming to assess the effectiveness of eight sessions of parent counselling. The primary outcome was the improvement of parents' coping abilities to achieve more effective support skills. Before treatment, 54% of parents showed poor coping resources whereas 43.7% of the sample improved after parent counselling. Parents with good coping resources responded significantly better to this treatment. Although future research is warranted, these preliminary findings support the effectiveness of parent counselling in ED.
