The role of autobiographical memory networks in the experience of negative emotions: how our remembered past elicits our current feelings

The present research examined the role of autobiographical memory networks on negative emotional experiences. Results from 2 studies found support for an active but also discriminant role of autobiographical memories and their related networked memories on negative emotions. In addition, in line with self-determination theory, thwarting of the psychological needs for competence, autonomy, and relatedness was found to be the critical component of autobiographical memory affecting negative emotional experiences. Study 1 revealed that need thwarting in a specific autobiographical memory network related to the theme of loss was positively associated with depressive negative emotions, but not with other negative emotions. Study 2 showed within a prospective design a differential predictive validity between 2 autobiographical memory networks (an anger-related vs. a guilt-related memory) on situational anger reactivity with respect to unfair treatment. All of these results held after controlling for neuroticism (Studies 1 and 2), self-control (Study 2), and for the valence (Study 1) and emotions (Study 2) found in the measured autobiographical memory network. These findings highlight the ongoing emotional significance of representations of need thwarting in autobiographical memory networks.     

Mother and infant affective involvement states and maternal depression

This study shows two different dimensional types of maternal depression, one dull and slow, the other stressed and irritable. When the quality of the infant attachment to mother is assessed, it is noted that the dimensional aspect of the maternal depression can be of some importance in the quality of the attachment. In fact, children are more inclined to develop an insecure–ambivalent attachment to their stressed depressed mothers, while children of slow depressed mothers are more insecure–avoiding. Thus, the dimensions of maternal depression can be an indicator of the type of insecure attachment of the infant at one year of age. We have also found that insecure children of depressed mothers express very little joy in the course of face-to-face interactions. A parallel can be established between the characteristics of the different affective dimensions of the maternal depression, the affective involvement state level of the partners, their synchrony or non-synchrony, the affective expression of the baby, and the type of insecure attachment to the mother. Thus, affective interaction may be an indicator of the child's development, both to assess the interaction and to evaluate the type of attachment shown by the child, indicating that previous interactive patterns have been internalized. © 1997 Michigan Association for Infant Mental Health     

Academic Citizenship: An Academic Colleagues’ Working Paper

Universities are facing a critical challenge; university citizenship has steadily declined over the last few decades. As a self-governing entity, most of the foundational elements of a university community are within its own control. As a result, the health and future welfare of the institution depends greatly on the quality of its leaders and robustness of its governing structure. These in turn depend on the quality of those undertaking leadership roles and serving on governing bodies and on the degree to which they reflect its values and aspirations. Maximising the probability that these desiderata will be achieved requires a broad-based faculty willingness to serve conscientiously on these bodies and to serve as administrators to be involved in selecting members, and to be involved on the myriad of sub-committees, task forces, departmental committees, and the like. It is not only an abdication of citizenship to leave governance and administration of the institution to a few willing faculty, it is dangerous and puts at risk the welfare of the institution. Even if these few were all able to place the welfare of the institution above their own particular agendas and their self-interest (not something on which to count), the process of self-selection could not be expected to result in a group that would adequately reflect, represent or understand the breadth and depth of the needs, aspirations and complex circumstances of the entire institution. The larger the pool of willing participants, the greater the probability that those selected will reflect best the institutional diversity. This paper draws out the rights and obligations of faculty citizens embedded in the structural arrangements common to universities in the western world. In part A we examine three fundamental components of those arrangements, components that collectively define certain rights and entail certain obligations of citizenship. These obligations flow in part from essential rights, and also in part from what is necessary to sustain the viability and vibrancy of the community. In Part B, we examine some of these essential obligations of citizenship. In Part C, we make recommendations about how to promote effective citizenship; these recommendations are collected after Part C under the heading “Recommendations.”     

Agent communication pragmatics: the cognitive coherence approach

Different approaches have investigated the syntax and semantics of agent communication languages. However, these approaches have not indicated how agents should dynamically use communications. Instead of filling this pragmatics gap, most approaches have mainly focused on the ‘structure’ of dialogues even though developers are more interested in agents’ capabilities of having ‘useful’ automated conversations with respect to their goals rather than in their abilities to structure dialogues. This led us to work on a theory of the use of conversations between agents. In this paper, we propose a pragmatics theory which extends and adapts the cognitive dissonance theory (a major theory of social psychology) to multi-agent systems by unifying it with the theory of coherence in thought and action that issues from computational philosophy of mind. Precisely, we show how this theory allows us to provide generic conceptual tools for the automation of both agent communicational behavior and attitude change processes. This new motivational model is formulated in terms of constraints and elements of cognition and allows us to define cognitive incoherences and dialogue utility measures. We show how these measures could be used to solve common problems and answer some critical questions concerning agent communication frameworks use. Finally, our exploration in applying the cognitive coherence pragmatics theory as a new communication layer over classical BDI agents is presented. It relies on our dialogue games based agent communication language (DIAGAL) and our dialogue games simulator toolbox (DGS). The resulting framework provides the necessary theoretical and practical elements for implementing our theory. In doing so, it brings in a general scheme for automatizing agents’ communicational behavior as it is exemplified in this article.     

Effects of manipulating valence and arousal components of mood on specificity of autobiographical memory

An important cognitive deficit in clinical depression is the inability to be specific in recalling personal memories, a phenomenon coined "overgeneral memory" by Williams and Broadbent. Although there is general consensus that overgeneral memory is not state-dependent, most of the evidence originates from studies of this effect in clinical populations. The two components of mood, valence and arousal, were manipulated to examine their influence on memory specificity in a nonclinical sample of university undergraduate students. In Exp. 1, a Velten procedure was used to induce elated, depressed, or neutral mood states. No difference was found in autobiographical memory specificity among the three groups. In Exp. 2, high and low arousal states were induced through physical exercise. A low arousal state resulted in an increased proportion of overgeneral memories, suggesting that this memory phenomenon may be influenced by the arousal component of mood.     

Executive functioning in normal aging: a study of action planning using the Zoo Map Test

A particularly important aspect of executive functioning involves the ability to form and carry out complex plans, that is to say planning. This study aimed to investigate planning in 18 older and 16 younger normal participants using an ecological planning subtask derived from the Behavioural Assessment of the Dysexecutive Syndrome test battery, the "Zoo Map Test." There are two trials. The first trial consists of a "high demand" version of the subtask in which the participants must plan in advance the order in which they will visit designated locations in a zoo (formulation level). In the second, or "low demand" version, the participant is simply required to follow a concrete externally imposed strategy to reach the locations to visit (execution level). The two-way ANOVAs mainly showed more difficulties in elderly adults than in younger adults, more difficulties in formulation level than in execution level, and lastly a greater difference between formulation and execution in older participants than in younger adults. These results suggest that elderly participants have some problems developing logical strategies whereas they are able to execute complex predetermined plans.     

Referential understanding of videos in chimpanzees (Pan troglodytes), orangutans (Pongo pygmaeus), and children (Homo sapiens)

Performance on identical search tasks based on cues directly perceived or indirectly perceived through video were compared among a group of 4 adult chimpanzees (Pan troglodytes), a group of 2 adult orangutans (Pongo pygmaeus), and a group of 36 children (between 2 and 3 years of age). Children comprehended directly perceived cues but had difficulty with video cues. In contrast, chimpanzees and 1 orangutan were successful in using video to guide their search for a hidden object. Two follow-up studies with 3-year-old children demonstrated the importance of more distinct perceptual and verbal cues in aiding children's understanding of video as referring to real-world events.
