A new inverted spectrum thought experiment

A version of the inverted spectrum thought experiment that disconfirms functionalism for the case of humans’ color experiences has typically been thought to require a certain kind of balancing act. What one needs, it has typically been thought, is a mapping of color experiences onto other color experiences that preserves the similarity and difference relationships among those experiences and the aspects of perceived colors underlying those similarities and differences. However, there are good reasons for being suspicious about whether that is possible when the palette of color experiences is that available to humans with normal vision. The new version of the thought experiment constructed here doesn’t depend on preserving those relationships. I argue that there is a coherent, metaphysically possible scenario in which two human color experiences—any two—can be seen to be functionally equivalent. The upshot is that functionalism fails for all human color experiences.     

Early development of letter specialization in left fusiform is associated with better word reading and smaller fusiform face area

A functional region of left fusiform gyrus termed “the visual word form area” (VWFA) develops during reading acquisition to respond more strongly to printed words than to other visual stimuli. Here, we examined responses to letters among 5‐ and 6‐year‐old early kindergarten children (N = 48) with little or no school‐based reading instruction who varied in their reading ability. We used functional magnetic resonance imaging (fMRI) to measure responses to individual letters, false fonts, and faces in left and right fusiform gyri. We then evaluated whether signal change and size (spatial extent) of letter‐sensitive cortex (greater activation for letters versus faces) and letter‐specific cortex (greater activation for letters versus false fonts) in these regions related to (a) standardized measures of word‐reading ability and (b) signal change and size of face‐sensitive cortex (fusiform face area or FFA; greater activation for faces versus letters). Greater letter specificity, but not letter sensitivity, in left fusiform gyrus correlated positively with word reading scores. Across children, in the left fusiform gyrus, greater size of letter‐sensitive cortex correlated with lesser size of FFA. These findings are the first to suggest that in beginning readers, development of letter responsivity in left fusiform cortex is associated with both better reading ability and also a reduction of the size of left FFA that may result in right‐hemisphere dominance for face perception.     

Reaction-time measures of stutterers and nonstutterers

Ten adult male stutterers and ten adult male nonstutterers participated in six reaction-time tasks designed to measure manual, acoustic, and laryngeal-region response latencies. The analysis revealed statistically significant differences between the groups for the acoustic data only. The results indicated that acoustic reaction-time differences are not accounted for by the speed of the general laryngeal response.     

Tortured families: a Coordinated Management of Meaning analysis

Torture is known to affect both the individual and the family. The aim of the present study was to reach a better understanding of the significance of communication and information about parental exposure to violence in torture-surviving families. The theoretical background is Social Constructionism and Coordinated Management of Meaning (CMM). In-depth interviews were carried out with 14 members of 3 Middle Eastern refugee families living in Denmark in which the father had been exposed to torture. The 3 families experienced their life stories and situations as refugees in very different ways, ranging from meaninglessness, discontinuance, and alienation to a sense of community, solidarity, and openness. Communications about past events were related to such meaning-providing contexts. The way in which parents talk with their children about torture and organized violence can be understood in terms of "stories told" and "stories lived." When stories told (e.g., the experience of torture and organized violence) are in contradiction to stories lived, a situation of ambiguity and uncertainty is created. The meaning-providing contexts for making sense of the family history of violence and exile can be more or less coherent or contradictory, and might result in a strengthened relationship or confusion, powerlessness, and action paralysis. Clinicians can help traumatized families deal with their past histories of violence by paying attention to such ambiguities and contradictions.
