The purpose of this study was to assess the role of common motor responses as the "speaker" behavior on stimulus class formation, and the emergence of functional classes. Experiment 1 examined whether training one motor response to a set of three stimuli and a second motor response to another set of three stimuli would result in correct category-sort responses for 5 typically developing prescho...

Since antiquity names have been very important to people. Naming from the past to the present has been continuously developed and has evolved into a variety of patterns. Each pattern has its own rules depending on local belief and language that has been developed until the present. In many cultures naming is not only important because every individual needs to have a name but have helpful names...

When asked to report the color of a target letter in a briefly presented word or pseudoword, Ss were more likely to report the color of letters from the same syllablelike unit than the color of other letters. Because Ss were not required to make a lexical decision or naming response, the multiletter units that are revealed by this task arise automatically. It was found that the syllablelike uni...

A series of experiments assessed masked priming for letters and words that are visually similar (SIM) and dissimilar (DIS) in upperand lower-case formats. For letters, robust DIS priming was obtained in a naming task, but this priming did not extend to a variety of non-naming tasks. For words, robust DIS priming was obtained in both naming and nonnaming tasks. SIM letter and word priming extend...

Whether pure alexia is a selective disorder that affects reading only, or if it reflects a more general visual disturbance, is highly debated. We have investigated the selectivity of visual deficits in a pure alexic patient (NN) using a combination of psychophysical measures, mathematical modelling and more standard experimental paradigms. NN's naming and categorization of line drawings were no...

We document the case of a patient (GV) w ho, following a left posterior brain lesion, showed a selective and severe deficit in naming visual objects and in reading letters, words, and numerals. Three sets of findings are critical for the interpretation of the patient's alexia. First, despite intact visual processing abilities and preserved ability to recognise the shape and orientation of lette...

The purpose of this appendix is to introduce (in a compact manner) the syntax and semantics of the most prominent DLs occurring in this handbook. More information and explanations as well as some less familiar DLs can be found in the respective chapters. For DL constructors whose semantics cannot be described in a compact manner, we will only introduce the syntax and refer the reader to the res...

A series of experiments assessed priming for single letters and words in a letter-by-letter reader (IH) when primes were displayed briefly (between 100-500 ms) and masked. Consistent with previous claims that letter-by-letter readers have difficulties accessing orthographic letter codes, IH failed to show normal cross-case priming for single letters in a naming task (e.g., a/A). Nevertheless, I...
