Mean reaction times obtained in a Sternberg memory-scanning task were examined for the effects of secobarbital at two doses (1.47 mg/kg and 2.94 mg/kg) spanning the dose range commonly used in clinical practice. Both doses slowed reaction time significantly, with a more pronounced effect at the high

β¦ Synopsis
Sternberg's (1969)
model of memory scanning processes is considered to be insufficient for verbal material. In Sternberg's model no considerations are given to coding and decoding processes which are relevant for vcrbM material. Usually Ss will represent letter strings of words as one unit with a specific meaning. If Sternberg's model should be valid for verbM material the time for coding and decoding of the memorized materiM has to be considered in addition to the time of coding the test stimulus, comparing the test item with the items of the memorized list and responding. Experimental data with different tasks to find a letter or a word in a list of words or a letter in a word can be explained adequately if coding and decoding processes for words are considered in the Sternberg model. Zusammen/assung. Es wird davon ausgegangcn, dab das Modell yon Sternberg (1969) ffir Suchprozcssc im Ged/~chtnis bei verbalem materiM unzureichend ist. Die Besonderheit verbMen Materials bcsteht darin, dM] es Vpn veranlaBt, physikalisch gegebene Buchstabensequenzen zu W5rtern zusammcnzufassen, die als Bedeutungseinheiten codiert werden. Wenn man in dem Modell yon Sternberg neben der Zeit fiir die Codierung des Testreizes, zum Vergleich des Testreizes mit eincr memorierten Liste und zur Aatwort zus~tzlich die Zeit zur Codierung und Dccodierung des memorierten verbMen Materials berficksichtigt, kSnnen experimentelle Daten zur Suche yon WSrtern oder Buchstaben in Wortlisten ad~quat erkl~rt werden.

Recently, theorists have suggested a close relation between the codes activated during language processing and those involved in STM. In order to further investigate this relationship, we examined the performance of an anomic patient, MS, to determine whether he would exhibit the same impairment in

The purpose of this study was to delineate the neural pathways involved in processing concrete and abstract words using functional magnetic resonance imaging (fMRI). Word and pseudoword stimuli were presented visually, one at a time, and the participant was required to make a lexical decision. Lexic
