The relationship between retrieval-induced forgetting, anxiety, and personality

Abstract Retrieval-induced forgetting (RIF) refers to the finding that the retrieval of a memory trace suppresses the retrieval of rival memory traces, and there is evidence that RIF reflects the effects of cognitive inhibition. The Attentional Control Theory (ACT) postulates that cognitive inhibition will be impaired by a high level of state anxiety, but the effect of anxiety on RIF has not previously been investigated. A sample of 116 participants were tested on the RIF procedure, and were also administered the Spielberger State Anxiety Inventory and the Big Five Personality Inventory. The results indicated a significant negative correlation between RIF scores and state anxiety, and a significant positive correlation between RIF scores and extraversion. However, a multiple regression analysis identified extraversion as the main predictor of RIF performance. None of the other personality factors correlated with RIF scores. These findings are consistent with the predictions of the ACT.     

Retrieval per se is not sufficient to trigger reconsolidation of human fear memory

Ample evidence suggests that consolidated memories, upon their retrieval, enter a labile state, in which they might be susceptible to change. It has been proposed that memory labilization allows for the integration of relevant information in the established memory trace (memory updating). Memory labilization and reconsolidation do not necessarily occur when a memory is being reactivated, but only when there is something to be learned during memory retrieval (prediction error). Thus, updating of a fear memory trace should not occur under retrieval conditions in which the outcome is fully predictable (no prediction error). Here, we addressed this issue, using a human differential fear conditioning procedure, by eliminating the very possibility of reinforcement of the reminder cue. A previously established fear memory (picture-shock pairings) was reactivated with shock-electrodes attached (Propranolol group, n=18) or unattached (Propranolol No-Shock Expectation group, n=19). We additionally tested a placebo-control group with the shock-electrodes attached (Placebo group, n=18). Reconsolidation was not triggered when nothing could be learned during the reminder trial, as noradrenergic blockade did not affect expression of the fear memory 24h later in the Propranolol No-Shock Expectation group. Only when the outcome of the retrieval cue was not fully predictable, propranolol, contrary to placebo, reduced the startle fear response and prevented the return of fear (reinstatement) the following day. In line with previous studies, skin conductance response and shock expectancies were not affected by propranolol. Remarkably, a double dissociation emerged between the emotional (startle response) and more cognitive expression (expectancies, SCR) of the fear memory. Our findings have important implications for reconsolidation blockade as treatment strategy for emotional disorders. First, fear reducing procedures that target the emotional component of fear memory do not necessarily affect the cognitive component and vice versa. Second, mere retrieval of the fear memory is not sufficient to induce its labilization and reconsolidation.     

Gay male attraction toward muscular men: Does mating context matter?

The purpose of this study was to examine gay men's perceived attractiveness of male figures based on short-term and long-term partner contexts. A sample of 190 gay adult men rated the attractiveness of line-drawings depicting male figures varying systematically in muscularity and body fat percentage in both short-term and long-term dating contexts. Mixed effects modeling was used to estimate the effects of figure (muscularity and body fat), dating context (short-term vs. long-term), and individual rater characteristics on attractiveness ratings. Results indicated that figure muscularity and body-fat had significant non-linear (i.e., quadratic) relationships with attractiveness ratings, and short-term dating context was associated with more discriminating ratings of attractiveness. Interactions between individual characteristics and figure characteristics indicated that the more available the individual and lower body fat, the more discriminating they were in ratings of attractiveness. The implications for future investigations considering both object and observer characteristics of attractiveness preferences are discussed.     

The Influence of Affective States on Cognitive Broadening/Narrowing: Considering the Importance of Motivational Intensity

Decades of research suggested that positive affective states broaden cognitive processes, whereas negative affective states narrow cognitive processes. More recent research suggests, however, that these conclusions may be premature. These past experiments often compared positive affects low in motivational intensity with negative affects high in motivational intensity. These past experiments, therefore, may have confounded affective valence with motivational intensity. Recent evidence suggests that motivational intensity rather than affective valence influences cognitive broadening/narrowing. That is, affective states of low motivational intensity (e.g., sadness, postgoal positive affect) broaden cognition, whereas affective states of high motivational intensity (e.g., disgust, pregoal positive affect) narrow cognition. We posit that narrowing occurs during affective states of high motivational intensity to aid organisms in acquiring desirable objects or avoiding aversive ones. In contrast, broadening occurs during affective states of low motivational intensity to open organisms to new opportunities.     

Concrete Construction Employees: When Does Procedural Fairness Shape Self‐Evaluations?1

According to the Group Value Model, group authorities and procedures communicate symbolic information to people about whether the group values or respects them. Employees for a concrete construction company completed a questionnaire about their work experiences in either English or Spanish. Among employees who identified more strongly with the concrete construction company, the quality of supervisor treatment predicted employees' feelings of respect and personal self-efficacy. Further, for employees who identified with the company, feeling respected by their colleagues mediated the relationship between fair treatment by a single supervisor and self-efficacy. Even when the working context encourages short term and instrumental goals, these results suggest that employees who identify with the company still care about fair treatment because of the self-relevant information it communicates to them.     

I haven't thought about this for years! Dating recent recalls of vivid memories

In three studies, we examined memories for previous recall. In Studies 1 and 2, undergraduates were asked whether they had vivid memories about various childhood events. After a one‐hour (Study 1) or 2‐week (Study 2) interval, they completed a second questionnaire containing new, but also previously presented childhood items. Participants estimated how recently they had thought about old and new items. A non‐trivial proportion of recent recalls of vivid childhood memories was dated incorrectly. In Study 3, women with recovered and continuous memories of childhood sexual abuse (CSA) completed the childhood events questionnaires used in studies 1 and 2. After a one‐hour interval, they indicated how recently they had thought about new, but also previously presented childhood items. Compared to women with continuous CSA memories, women with recovered memories underestimated their prior remembering. Copyright © 2005 John Wiley & Sons, Ltd.     

Relationships between job evaluation ratings and self-ratings of job characteristics

Self-ratings by 308 shop workers of their job variety, autonomy, task identity, and skill challenge correlate significantly with ratings by observers of the jobs' skill requirements. Self-ratings, however, are unrelated to observers' estimates of the physical demands of the jobs or to environmental conditions of the work. The self-ratings and observer measures provide complementary, not substitute, information. Self-ratings can signal person-job dysfunctions, and more objective job measures can identify possible sources of the dysfunctions. Modifications to job characteristics measures are discussed and suggestions are made to begin a new phase of programmatic job characteristics research.     

Working wives and women's rights: The connection between the employment status of wives and the feminist attitudes of husbands

Women in the labor force tend to have more profeminist attitudes on women's rights and sex roles than women working in the home. In turn, the husbands of wives employed outside the home are more supportive of feminist positions than the husbands of wives working in the home. The difference is greater on attitudes relating to employment and traditional roles in the home and family but also occurs on some items dealing with political rights and general sexual equality. The causal connection between the attitude of husbands and the labor-force status of their wives can not be demonstrated, but causation is believed to work in both directions.This research was done for the General Social Survey project directed by James A. Davis and Tom W. Smith (GSS Technical Report No. 41). The project is funded by National Science Foundation Grant SES-8118731.     

Inducing psychotherapy: Hypnotic analogue for brief psychotherapy

These authors contend that hypnosis is a useful analogue and change accelerator for brief psychotherapy.A deep structure of psychotherapy is described by Frank, as making changes in a person's assumptive world so he/she may live more effectively. Cognitive alterations arise from new emotional experiences or emotional schemas which in turn have arisen in the context of a therapy relationship.A parsimonious recipe for the structure of brief psychotherapy is hypnosis. Hypnotic analogues for psychotherapy emerge from many theoretical backgrounds. After integrating aspects of these theories, a general analogue of hypnosis for the structure of brief psychotherapy is suggested. The analogue addresses induction, power issues, deepening, making and solidifying cognitive alterations, and endings.
