Making too many enemies: Hutto and Myin’s attack on computationalism†

We analyse Hutto & Myin's three arguments against computationalism [Hutto, D., E. Myin, A. Peeters, and F. Zahnoun. Forthcoming. “The Cognitive Basis of Computation: Putting Computation In Its Place.” In The Routledge Handbook of the Computational Mind, edited by M. Sprevak, and M. Colombo. London: Routledge.; Hutto, D., and E. Myin. 2012. Radicalizing Enactivism: Basic Minds Without Content. Cambridge, MA: MIT Press; Hutto, D., and E. Myin. 2017. Evolving Enactivism: Basic Minds Meet Content. Cambridge, MA: MIT Press]. The Hard Problem of Content targets computationalism that relies on semantic notion of computation, claiming that it cannot account for the natural origins of content. The Intentionality Problem is targeted against computationalism using non-semantic accounts of computation, arguing that it fails in explaining intentionality. The Abstraction Problem claims that causal interaction between concrete physical processes and abstract computational properties is problematic. We argue that these arguments are flawed and are not enough to rule out computationalism.     

Recall of morphologically complex forms is affected by memory task but not dyslexia

The authors studied the effect of morphological complexity on working memory in list recall tasks with base words (boy), inflected words (boy + 's) and derived words (boy + hood) in a morphologically rich language: Finnish. Simple serial recall was compared to complex working memory tasks, combining word recall with sentence verification in 8-year-old normally reading participants, dyslexic children, and adults. The normally reading children performed better than dyslexic children on both memory tasks and a test of morphology. Base words were better recalled than morphologically complex words. Memory was better for derived than inflected words in simple but not complex span tasks. There was no interaction between word type and reading group and thus no suggestion of dyslexia being associated with specific problems to represent complex morphology in working memory. Morphological processing in working memory appeared to depend on the task.     

Pupil Dilation as a Measure of Processing Load in Simultaneous Interpretation and Other Language Tasks

The present study tested whether the pupillary response can be applied to study the variation in processing load during simultaneous interpretation. In Experiment 1, the global processing load in simultaneous interpretation as reflected in the average pupil size was compared to that in two other language tasks, listening to and repeating back an auditorily presented text. Experiment 1 showed clear differences between the experimental tasks. In Experiment 2, the task effect was replicated using single words as stimuli. Experiment 2 showed that momentary variations in processing load during a lexical translation task are reflected in pupil size. Words that were chosen to be more difficult to translate induced higher levels of pupil dilation than did easily translatable words. Moreover, repeating back words in a non-native language was accompanied by increased pupil dilations, in comparison to repetition in the subject's native language. In sum, the study lends good support to the use of the pupillary response as an indicator of processing load.
