Abstract

Latent semantic analysis (LSA) is a model of knowledge representation for words. It works by applying dimension reduction to local co-occurrence data from a large collection of documents after performing singular value decomposition on it. When the reduction is applied, the system forms condensed representations for the words that incorporate higher order associations. The higher order associations are primarily responsible for any semantic similarity between words in LSA. In this article, a memory model is described that creates semantic representations for words that are similar in form to those created by LSA. However, instead of applying dimension reduction, the model builds the representations by using a retrieval mechanism from a well-known account of episodic memory.

Contingency learning without awareness: evidence for implicit control.

The results of four experiments provide evidence for controlled processing in the absence of awareness. Participants identified the colour of a neutral distracter word. Each of four words (e.g., MOVE) was presented in one of the four colours 75% of the time (Experiments 1 and 4) or 50% of the time (Experiments 2 and 3). Colour identification was faster when the words appeared in the colour they were most often presented in relative to when they appeared in another colour, even for participants who were subjectively unaware of any contingencies between the words and the colours. An analysis of sequence effects showed that participants who were unaware of the relation between distracter words and colours nonetheless controlled the impact of the word on performance depending on the nature of the previous trial. A block analysis of contingency-unaware participants revealed that contingencies were learned rapidly in the first block of trials. Experiment 3 showed that the contingency effect does not depend on the level of awareness, thus ruling out explicit strategy accounts. Finally, Experiment 4 showed that the contingency effect results from behavioural control and not from semantic association or stimulus familiarity. These results thus provide evidence for implicit control.

What's so special about the average face?

The past few years have seen a marked increase in our understanding of how faces are represented in the brain, with the discovery of new anatomical structures and new algorithms for representing faces. Still, the basic computational mechanism used by the primate visual system to identify faces remains a topic of intense debate. Are faces represented by matching to a set of stored exemplars, or by measuring the distance from a standard prototype along a set of different axes? A recent article by Rhodes and Jeffery provides compelling psychophysical evidence in favor of the latter 'axis' model.

Emotional representation in facial expression and script A comparison between normal and autistic children.

The paper explored conceptual and lexical skills with regard to emotional correlates of facial stimuli and scripts. In two different experimental phases normal and autistic children observed six facial expressions of emotions (happiness, anger, fear, sadness, surprise, and disgust) and six emotional scripts (contextualized facial expressions). In the second place, the effect of emotional domain (different emotions) in decoding was explored. A semantic grid was applied to conversational line, including two levels of data: the lexical adequacy index (correct decoding of emotion) and the emotional vocabulary (such as the causal representation and the hedonic valence of the stimulus). Log-linear analysis showed different representations across the subjects, as a function of emotion, task and pathology. Specifically, childrens' lexical competence was well developed for some emotions (such as happiness, anger, and fear), and as a function of type of task, that is script was better represented than face. Between the main linguistic indexes, causal relation was a prototypical index for emotional conceptualization. Finally, pathology affected children's performance, with an increased "facilitation effect" for autistic children in the script condition.
