In two experiments, Brookshire, Ivry, and Casasanto showed that words with positive and negative emotional valence can activate spatial representations with a high degree of automaticity, but also that this activation is highly context dependent. Lebois, Wilson-Mendenhall, and Barsalou reported that they “aimed to replicate” our study but found only null results in the “Brookshire et al. replication” conditions. Here we express concerns about three aspects of this paper. First, the study was not an attempt to replicate ours; it was (...) a different study that adapted our method. Second, Lebois et al. did not accurately represent our theoretical position. Third, Lebois et al.’s main conclusion, that spatial congruity effects depend on the task context, was not supported by their data. Despite these concerns, we agree with Lebois et al.'s overall message that spatial aspects of words' meanings are activated differently in different contexts. This was a main conclusion of our study as well. (shrink)

Ten cerebellar patients were compared to 10 control subjects on a verbal working memory task in which the phonological similarity of the words to be remembered and their modality of presentation were manipulated. Cerebellar patients demonstrated a reduction of the phonological similarity effect relative to controls. Further, this reduction did not depend systematically upon the presentation modality. These results first document that qualitative differences in verbal working memory may be observed following cerebellar damage, indicating altered cognitive processing, even though behavioral (...) output as measured by the digit span may be within normal limits. However, the results also present problems for the hypothesis that the cerebellar role is specifically associated with articulatory rehearsal as conceptualized in the Baddeley–Hitch model of working memory.

We review evidence from neuropsychological studies of patients with damage to the cerebellum that suggests cerebellar involvement in four general categories of cognition: (1) speech and language; (2) temporal processing; (3) implicit learning and memory; (4) visuospatial processing and attention. A relatively strong case can be made for cerebellar contributions to language (including speech perception, lexical retrieval, and working memory) and to temporal processing. However, the evidence concerning cerebellar involvement in non-motor implicit learning and visuospatial processing is more equivocal. We (...) argue that cerebellar contributions to cognition are computationally plausible, given its reciprocal connectivity with the cerebral cortex, and suggest that this function of the cerebellum may be an example of an evolutionary process by which mechanisms originally evolved for one function (in this case, motor control) are adapted to other functions (cognition).
