Cognitive and emotional influences in anterior cingulate cortex

Anterior cingulate cortex (ACC) is a part of the brain's limbic system. Classically, this region has been related to affect, on the basis of lesion studies in humans and in animals. In the late 1980s, neuroimaging research indicated that ACC was active in many studies of cognition. The findings from EEG studies of a focal area of negativity in scalp electrodes following an error response led to the idea that ACC might be the brain's error detection and correction device. In this article, these various findings are reviewed in relation to the idea that ACC is a part of a circuit involved in a form of attention that serves to regulate both cognitive and emotional processing. Neuroimaging studies showing that separate areas of ACC are involved in cognition and emotion are discussed and related to results showing that the error negativity is influenced by affect and motivation. In addition, the development of the emotional and cognitive roles of ACC are discussed, and how the success of this regulation in controlling responses might be correlated with cingulate size. Finally, some theories are considered about how the different subdivisions of ACC might interact with other cortical structures as a part of the circuits involved in the regulation of mental and emotional activity.     

Effect of personal involvement in traumatic events on memory: The case of the Dolphinarium explosion

The association between memories of the terrorist explosion at the Dolphinarium discotheque in Tel Aviv and the level of personal involvement in the explosion was investigated. Memories of injured victims, uninjured eyewitnesses, and uninvolved controls who learned about the explosion from the mass media were compared. It was expected that memory of the explosion would be most and least detailed and accurate among the victims and the controls, respectively. The participants responded to an open-ended question about the explosion, as well as to specific and multiple-choice questions. Data analyses showed that the victims and the eyewitnesses remembered more details than the controls, and that the victims remembered both central and peripheral details more accurately than the other participants. Degree of involvement in the same traumatic experience was thus shown to be differentially associated with memory accuracy.     

Collaborative remembering of emotional events: The case of Rabin's assassination

Individual and collaborative remembering of the assassination of Israel's Prime Minister, Itzhak Rabin, were compared. In line with previous laboratory findings on memory of neutral stimuli, it was hypothesised that collaborative remembering (three individuals reaching a common response) and nominal remembering (three individual responses pooled together) of the assassination would be more accurate than individual remembering. A total of 146 participants responded (115 individually and 120 in groups of three) to open-ended and multiple-choice questionnaires (among them, 89 responded twice with a week of intertest interval) about Rabin's assassination and the events that preceded and followed it. Data analysis showed that the collaborative responses to the open-ended questionnaire contained more details (both accurate and inaccurate) than the individual responses, and that the responses to the multiple-choice questionnaire were more accurate than the individual responses. However, the collaborative responses contained fewer details (both accurate and inaccurate) than the nominal responses. Responses to the two questionnaires were more accurate on the retest when they followed collaborative rather than individual responses on the original test. The inferiority of the collaborative relative to the nominal remembering was attributed to collaborative inhibition, whereas the positive effect of collaborative remembering on performance on the retest was attributed to the contribution of contextual cues.     

Resilience and the burnout-engagement model in formal caregivers of the elderly

This paper investigates the relationship between resilience and positive/negative mental aspects of psychological well-being in formal caregivers for the elderly. The sample consisted of 265 caregivers who work in different residential homes in Extremadura and Castilla y León (Spain). The instruments used included the Connor-Davidson Resilience Scale , the Maslach Burnout Inventory-General Survey and the Utrecht Work Engagement Scale. The most significant findings show that caregivers with higher levels of resilience also have higher levels of professional efficacy and job engagement (vigor, dedication and absorption) and appear to be less emotionally exhausted or cynical than caregivers with lower levels of resilience. It cannot be concluded that more resilient caregivers will not get burned out, but they develop better engagement skills. As they strengthen these personal attributes, they become less vulnerable to burnout.     

Suicide and the suicidal body. 2002 Dublin Award Address

This paper focuses on the bodily experiences and attitudes toward the body in suicidal individuals. It is argued that bodily experiences and attitudes toward the body, such as rejection of the body, detachment, numbness, physical anhedonia, and lack of protection can facilitate acts of self-destruction. This argument is supported by theories of developmental psychology, theories on suicide, and empirical data. It is demonstrated that suicidal individuals experience their body differently from other populations and that these are related to suicidal behavior.     

LATERAL DIFFERENCES IN DIGIT AND NONSENSE FORM RECOGNITION AMONG JAPANESE AND ISRAELI SUBJECTS

Digit and nonsense figure sequences which were arranged vertically or horizontally, were tachistoscopically presented to native Japanese and Hebrew readers to the left or right visual field. Both groups showed a right visual field superiority in the horizontal condition and a strong tendency toward a right visual field superiority in the vertical condition for the digit sequences, and no visual field difference was shown both in the vertical and horizontal conditions for the nonsense figure sequences. There was no difference between Japanese and Israelis in either the direction or the degree of the visual field differences. A slight influence of the different directional reading biases between both groups appeared in the analysis of serial position effect in recall, but this influence was not prominent. Based on these findings, cross-cultural influences on cerebral functioning were discussed.     

Use of a common software system for collaborative clinical research on attentional processes in schizophrenia and ADHD

MacArthur Network III, consisting of five nodes (locations) and over 100 investigators, was formed in 1983 to conduct collaborative clinical research on risk and protective factors associated with psychiatric disorders. The common measurement of attentional dysfunction associated with two specific disorders (schizophrenia and attention deficit-hyperactivity disorder) was a goal of a subgroup of 11 Network III investigators. In this paper, the experiences with five approaches for implementing common protocols on laboratory computers for collaborative clinical research are described. The reasons for selecting the approach provided by Schneider’s (1988) MEL system are presented and discussed.     

Emotional modulation of attention orienting: A classical conditioning study

Emotional modulation of attention shifting was investigated in Posner's (1980) spatial orienting task by conditioning the attention cue to an aversive white noise. Prior to the attention task, the Conditioning group received a 90dB white noise unconditioned stimulus (UCS) contingent upon the frame-lit rectangle attention cue, while the Control group received non-contingent presentations. The Conditioning group evidenced greater skin conductance responses to the frame-lit rectangle in the conditioning phase, reflecting an electrodermal conditioned response. In the attention phase, the frame-lit rectangle served as the attention cue in the spatial orienting task. The Conditioning group showed equally fast reaction times (RTs) to targets presented outside the location of the cue as to targets at the same location as the cue, reflecting elimination of the cognitive cost usually involved in shifting attention. The Control group evidenced the regular cost of shifting attention away from the location of the cue. The Conditioning group also evidenced a larger N1-component with a parietal distribution of the event-related brain potentials to the cue and a larger N1-component at the frontal regions to targets presented outside the cued location. This suggests that both visual orienting to the cue and attention shifting from cue to target on invalid trials were amplified by the emotional salience attached to the cue through the classical conditioning procedure.     

After-school activities and the development of low-income urban children: a longitudinal study.

After-school activities of 194 African American and White children from low-income households were studied from 3rd to 5th grade to determine relations with (a) child, family, and contextual variables and (b) children's adjustment over time. Girls were more likely to engage in academic activities and socializing, whereas boys were more likely to play coached sports. Children who attended after-school programs spent more time on academic and extracurricular activities, whereas children in informal care settings spent more time watching TV and hanging out. Evidence of transactional relations between after-school activities and child adjustment was found. Time spent in activities between 3rd and 5th grades was related to children's adjustment in 5th grade. In addition, child adjustment measured in 3rd grade was associated with time in different activities in 5th grade.
