Selective activation effects of concurrent verbal and spatial memory loads in left-handed and right-handed adults

Subvocal rehearsal of neutral and affective words interferes with left-hemisphere performance and facilitates right-hemisphere performance

“…These interference effects are inconsistent with recent dual-task research which has demonstrated priming effects with similar simple and noneffortful tasks (Kinsbourne & Byrd, 1985;Van Strien & Bouma, 1990). Though manipulation checks indicate the apparent ease of these tasks, they may not have been sensitive enough to evaluate the tasks' effort requirements.…”

“…Specifically, word-recall percentage may poorly reflect the effort or processing demands of verbal rehearsal during the six slide presentations. In contrast, Van Strien and Bouma (1990) found priming effects when subvocal rehearsal was required during only one slide presentation. Despite the manipulation checks, the length of the experimental tasks suggest that they required more effort and processing than initially hypothesized.…”

“…For example, Kinsbourne (1970) found that subvocal verbal rehearsal facilitated gap detection in the right visual field (RVF), whereas across visual fields without a verbal load performance was equal. Van Strien and Bouma (1990) recently substantiated these findings and demonstrated the efficacy of verbal material in facilitating performance in the RVE Replication of these findings, however, has proved difficult. Boles (1979) found that subvocalization of six words interfered with RVF form recognition, but no interference was noted during two-word rehearsal.…”

Altered visual field asymmetry for lexical decision as a result of concurrent presentation of music fragments of different emotional valences

“…It is not clear whether this is a consequence of the positive valence of the nonthreatening words or is a consequence of the verbal nature of the words (priming the verbal left hemisphere). In an earlier study (Van Strien & Bouma, 1990), we also found RVF letter-naming improvement as a consequence of the concurrent presentation of neutral words. Van Strien and Heijt (1995) hypothesized that, with threatening words, left hemisphere priming due to the verbal nature of the words is inhibited by right hemisphere priming due to the negative valence of the words.…”

The magical number 4 in short-term memory: A reconsideration of mental storage capacity

“…In an activation-based system, instead, an irrelevant memory load may sometimes pre-activate structures and thus enhance performance. The latter proved to be the case (e.g., Hellige & Cox 1976;van Strien & Bouma 1990).…”
