Sequential remembering and lived remembering in the flow of experience: a videographic study / Recuerdo secuencial y recuerdo vivido en el curso de la experiencia: un estudio videográfico

Abstract

During the last 30 years the discussion on memory and remembering has advanced from a strictly cognitive perspective to a broader view, involving the body in these processes. Thus, the present article aims to recover Henri Bergson’s main ideas — published more than a century ago — emphasizing the tight relation between immediate experience, memory and bodily movements. First, contemporary perspectives on memory are reviewed. Afterwards, the results from a videographic study are presented, showing how deeply the body is engaged in the act of remembering. These results evidence the presence of two different ways of remembering: sequential and lively-experienced.     

Do humans and baboons use the same information when categorizing human and baboon faces?

What information is used for sorting pictures of complex stimuli into categories? We applied a reverse correlation method to reveal the visual features mediating categorization in humans and baboons. Two baboons and 6 humans were trained to sort, by species, pictures of human and baboon faces on which random visual noise was superimposed. On ambiguous probe trials, a human-baboon morph was presented, eliciting "human" responses on some trials and "baboon" responses on others. The difference between the noise patterns that induced the two responses made explicit the information mediating the classification. Unlike the humans, the baboons based their categorization on information that closely matched that used by a theoretical observer responding solely on the basis of the pixel similarities between the probe and training images. We show that the classification-image technique and principal components analysis provide a method to make explicit the differences in the information mediating categorization in humans and animals.     

The social face of emotion recognition: Evaluations versus stereotypes

The goal of the present paper was to demonstrate the influence of general evaluations and stereotype associations on emotion recognition. Earlier research has shown that evaluative connotations between social category members and emotional expression predict whether recognition of positive or negative emotional expressions will be facilitated (e.g. Hugenberg, 2005). In the current paper we tested the hypothesis that stereotype associations influence emotion recognition processes, especially when the difference between valences of emotional expressions does not come into play. In line with this notion, when participants in the present two studies were asked to classify positive versus negative emotional expressions (i.e. happy versus anger, or happy versus sadness), valence congruency effects were found. Importantly, however, in a comparative context without differences in valence in which participants were asked to classify two distinct negative emotions (i.e. anger versus sadness) we found that recognition facilitation occurred for stereotypically associated discrete emotional expressions. With this, the current results indicate that a distinction between general evaluative and cognitive routes can be made in emotion recognition processes.
