Age-associated memory impairment—pathological memory decline or normal aging?

The aim of the study was to determine whether the memory capacity of individuals with age-associated memory impairment (AAMI) over a period of approximately 3½ years declines more, if at all, than the memory capacity of persons without AAMI. Four computerized and three non-computerized memory tests, a naming test, and a test of visuo-motor speed were administered twice. Two estimates of intellectual capacity were made, one at the first examination and the other 3½ years later. One person in the AAMI group (n=44) developed vascular dementia. The group of AAMI subjects did less well on two of the seven memory tests after 3½ years than they did initially; the control group (n=18) had lower scores on one memory test at follow-up than they had previously. The data suggest that the memory capacity of subjects with AAMI is not pathologically impaired. The general intellectual level significantly influences whether an individual with memory complaints will be classified AAMI or not. People with high intelligence are less likely than people with lower intellectual capacity to fulfill the AAMI criteria. This suggests that AAMI lacks in construct validity.     

Perceptions of Sexual Harassment as a Function of Target's Response Type and Observer's Sex

Although research has investigated definitionsand prevalence of sexual harassment, little is knownabout responses to sexual harassment. Therefore, thepresent study was designed to explore how individuals interpret the communication of various targetresponses. One hundred and twenty employees fromhealthcare settings were randomly assigned to one offour conditions. The majority of the individuals in the sample was White-European American (75%) whilethe remaining 25% was comprised of minority members. Theconditions contained a video-taped interaction betweentwo co-workers, one male and one female. The male's behavior in each interaction continuedto escalate to the point of sexual harassment while thefemale's responses varied. There were two passiveresponses and two assertive responses. After viewing the short video participants responded toquestions assessing their perceptions of theinteraction. Results indicated there were no differencesin perceptions between men and women when viewing thevarious conditions. There were, however, differencesfound between the assertive conditions and the passiveconditions. Specifically, assertive responses areperceived as more effective than passive responses in communicating unwelcomeness and in deterringthe initiator's persistence. However, consistent withthe research on responses to sexual harassment,perceptions of sexual harassment appear to be based more on the initiator's behavior than on thetarget's responses.     

Close Encounters in the Liminal Zone: Experiments in Imaginal Communication Part I

The phenomenology of the experience of being in psychic contact with another person was explored in a series of observations using a novel dyadic interaction in imaginal space. Research participants working in pairs with eyes closed received instructions to imagine being in mental contact with one another for three minutes while they observed their internal experiences. Their reports indicated that the imagined contact was experienced as real, as intimate, and aroused the ambivalences usually associated with intimacy as well as phenomena suggestive of projective identification effects. This first part demonstrated that the liminal zone, or the transitional space between individuals, can be experimentally observed through the imagination. Part II of this report will present evidence that the experienced psychic contact was more than 'just imagination', and involved transpersonal interactions, including suggestions of synchronicity and telepathy.     

Coding strategies,perceptual grouping,and the “variability effect” in free recall

Three experiments examined the effects of constant vs. varied input of letter strings on recall, and then examined the effects of such training in the learning of new lists of letter strings. Letter strings were constructed from pairs of trigrams spatially grouped, and were presented either consistently or with different spatial groupings on successive presentations. In Experiments I and II, varied input produced substantially greater recall than constant input. When transferred to a new list of letter strings, containing either the same general structure or a new scrambled structure, recall of the second list was determined primarily by conditions of first-list input, and unaffected by second-list structure. Although the "variability effect" did not appear in the training phase of Experiment III, Varied input led subjects to regroup or integrate the letter sequences more frequently and produced similar transfer effects as in Experiments I and II.     

AN INVESTIGATION OF THE INTEGRAL NATURE OF THE SOVIET CONCEPT OF SET

Cette recherche se propose d'étudier le caractère intégral de la notion de “set” telle qu'elle est décrite dans la théorie d'Uznadze. Deux concepts de base sont définis opérationnellement: l'objectification, qui se révèle dans le langage parlé et l'écriture, et la personnalité, qui peut être observée au moyen de tests appropriés. Cent quatre-vingt-six sujets d'un âge moyen de 21 ans ont participé à cette étude. Les mesures des traits de personnalité ont été obtenues par le EPI (Eysenck Personality Inventory) et le MMPI (Minnesota Multiphasic Personality Inventory). Le langage a été analysé à travers les dissertations écrites par chaque sujet. Les mesures de personnalité, de langage et de “set” ont été soumises à une analyse factorielle qui a permis d'extraire huit facteurs interprétables. Les résultats n'apportent qu'un soutien réduit à la thèse d'Uznadze concernant la nature intégrale de la notion de “set”.
