Affectivity in Its Relation to Memory

It seems obvious that various feelings (various kinds of affectivity) are memorized, forgotten, and recollected to various degrees. Some of them are forgotten. Some of those forgotten can be recollected, while others are lost forever. For example, short and long-lasting feelings and shallow and deep feelings are memorized and remembered in different ways. In this paper I analyse from a conceptual point of view several categories of memory-of-feelings and offer a comprehensive map of them. In the end, the richness of categories in the realm of memory is interpreted as a proof of the intricacy of affectivity.     

The impact of communal-mastery versus self-mastery on emotional outcomes during stressful conditions: a prospective study of Native American women

Past research has examined the stress resiliency of individuals high in sense of personal-mastery. However, it has been theorized that within more collectivist cultures, a sense of shared efficacy, which we call communal-mastery, may be more central to people's resiliency in the face of challenging life circumstances. We compared the impact of sense of self-mastery (i.e., I am the key to my success) to that of communal-mastery (i.e., I am successful by virtue of my social attachments) in a prospective study among a group of rural 103 Native American women residing on Indian Reservations in Montana. We found that women high in communal-mastery experienced less increase in depressive mood and anger, especially when faced with high stress circumstances, than women who were low in communal-mastery. In addition, the beneficial impact of communal-mastery was found to be more effective than self-mastery for these women.     

Action-based and vision-based selection of input: Two sources of control

In the first part of this paper we review evidence suggesting that there exists a mechanism that selects input on the basis of its similarity to the required action. This response-based input selection differs from the more established space- and object-based input selection in that it is not constrained by the structure of the input. Our evidence suggests that the two-choice Stroop effect is caused by this response-based selection mechanism. By contrast, it is known that the flanker effect is determined by the space- and object- based selection mechanisms. We explore whether the conflict resolution of the Stroop and flanker tasks is different as well by embedding these two tasks in a PRP (Psychological Refractory Period) paradigm. We show that the Stroop and the PRP effects are additive whereas the flanker and the PRP effects are underadditive, suggesting that the processes in charge of the conflict resolution in the Stroop and the flanker tasks are indeed different. We discuss possible reasons for this difference, and discuss possible ways in which the response-based mechanism can be implemented in information processing models.     

Opportunistic use of cognitive smokescreens by araneophagic jumping spiders

Little is known about how a prey species' cognitive limitations might shape a predator's prey-capture strategy. A specific hypothesis is investigated: predators take advantage of times when the prey's attention is focussed on its own prey. Portia fimbriata, an araneophagic jumping spider (Salticidae) from Queensland, is shown in a series of 11 experiments to exploit opportunistically a situation in which a web-building spider on which it preys, Zosis genicularis (Uloboridae), is preoccupied with wrapping up its own prey. Experimental evidence supports three conclusions: (1) while relying on optical cues alone, P. fimbriata perceives when Z. genicularis is wrapping up prey; (2) when busy wrapping up prey, the responsiveness of Z. genicularis to cues from potential predators is diminished; and (3) P. fimbriata moves primarily during intervals when Z. genicularis is busy wrapping up prey. P. fimbriata's strategy is effective partly because the wrapping behaviour of Z. genicularis masks the web signals generated by the advancing P. fimbriata's footsteps and also because, while wrapping, Z. genicularis' attention is diverted away from predator-revealing cues.
