REALITY MONITORING,PSYCHOLOGICAL TOOLS,AND COGNITIVE FLEXIBILITY IN BILINGUALS: THEORETICAL SYNTHESIS AND PILOT EXPERIMENTAL INVESTIGATION*

An attempt was made to bring about a theoretical synthesis of such seemingly unrelated concepts as ‘reality monitoring’ (belonging to contemporary American cognitive psychology), ‘psychological tools’ (suggested by Russian psychologist, Lev Vygotsky in the 1930s), and ‘cognitive flexibility in bilinguals’ (developed by Canadian researchers in the 1970s). Psychological tools of symbolic character which-as Vygotsky and his followers suggested-mediate human actions and mental operations, were shown to improve reality monitoring, i.e., subject's ability to discriminate between memories of words that he/she either spoke or merely thought. The concept of cognitive flexibility was applied to reality monitoring in Russian-English bilinguals. It was shown that greater cognitive flexibility associated with balanced bilingualism enhances a subject's ability to discriminate memories of words said and words thought. Suggestions are made concerning further possible experimental investigations.     

The Primary Prevention of Illness: Social Systems and Personal Power

There is evidence to be inferred from statistics about health status and mortality rates that a large proportion of illness and premature death is preventable. Primary prevention programmes appear to have had only limited success when individuals need to take responsibility for preserving their own health. This paper examines the concept of primary prevention and its assumptions, including the need to increase the sense of personal power of individuals. It also deals with some of the problems for primary prevention policies and their implementation. Other primary prevention issues such as ethical and legal considerations. cost-benefits, foci of programmes, and the specification of goals and objectives, are considered. We propose public (government) policies to broaden the concept of health sciences for research and practice, and to give a high priority for resource allocation to prevention of illness and promotion of health, including funding of interdisciplinary research teams. We advocate taking a general systems theory approach to prevention, while enhancing and developing the sense of personal power of individual members of social systems.     

Avoidance conditioning as a function of appetitive stimulus pretraining: Response and stimulus transfer effects

Pretrained appetitive discriminative stimuli were used as warning signals in subsequent avoidance learning. In Expt 1 identical responses were required in pretraining and in avoidance learning. An appetitive S+ facilitated avoidance learning in rats in comparison to S? or a stimulus previously uncorrelated with food. In Expt 2, the type of response in pretraining and in avoidance learning was varied. Groups with homogeneous responses in the two situations replicated Expt 1 results, whereas groups with different responses in pretraining and avoidance learning failed to show an advantage when S+ served as warning; in the heterogeneous response groups, S? was as effective as S+. Inhibitory factors in the heterogeneous groups were discussed as an explanation for these results.     

Disruptive effects of prior information on tachistoscopic recognition

Smith, Haviland, Reder, Brownell, and Adams (1976) found tachistoscopic letter recognition to be disrupted by advance information about possible letter alternatives. An association of “before-disruption” with a bias to respond “same” in same-different judgment led Smith et al. to conclude that incidental mask features corresponding to a precued letter were erroneously incorporated into the target letter decision. Experiments 1 and 2 in the present study failed to replicate the before-disruption effect under conditions similar to those of Smith et al., although precuing produced a strong bias to respond “same.” Similarity between “same” and “different” alternatives was manipulated in Experiment 3 by selecting letter pairs differing in one critical feature (P-R, O-Q, C-G, F-E) for one group of subjects, and re-pairing the same letters (P-G, O-E, C-R, F-Q) for another group. Contrary to Smith et el., precuing interacted significantly with pair similarity, such that before-disruption occurred only with similar alternatives. In contrast, precuing produced equivalent “same-bias” in both groups. The dependence of before-disruption on pair similarity was extended to two-alternative forced-choice recognition in Experiment 4. Together with inconsistencies in the Smith et al. data and more detailed analysis of present recognition errors, the results suggest (1) the before-disruption and same-bias effects of precuing are mediated by separate mechanisms, and (2) before-disruption reflects loss of target letter information rather than direct incorporation of extraneous mask features.
