Disrupted retrieval in directed forgetting: a link with posthypnotic amnesia

Certain reliable findings from research on directed forgetting seem difficult to accommodate in terms of the theoretical processes, such as selective rehearsal or storage differentiation, that have been put forward to account for directed-forgetting phenomena. Some kind of "missing mechanism" appears to be involved. In order to circumvent the methodological constraints that have limited the conclusions investigators could draw from past experiments, a new paradigm is introduced herein that includes a mixture of intentional and incidental learning. With this paradigm, a midlist instruction to forget the first half of a list was found to reduce later recall of the items learned incidentally as well as those learned intentionally. This result suggests that a cue to forget can lead to a disruption of retrieval processes as well as to the alteration of encoding processes postulated in prior theories. The results also provide a link between intentional forgetting and the literature on posthypnotic amnesia, in which disrupted retrieval has been implicated. With each of these procedures, the information that can be remembered is typically recalled out of order and often with limited recollection for when the information had been presented. It therefore was concluded here that retrieval inhibition plays a significant role in nonhypnotic as well as in hypnotic instances of directed forgetting. The usefulness of retrieval inhibition as a mechanism for memory updating was also discussed.     

The prevalence of despair in intractable conflicts: Direct messages of hope and despair affect leftists,but not rightists

In contexts of long-term conflict, it often seems easier to spread despair than to instill hope. The prevalence of despair, an emotion that promotes apathy, in contexts that so desperately need hope, an emotion that promotes conciliation, calls for further investigation. One possibility is that messages of hope and despair have different effects on people based on their political ideology. In the present research we examined the effect of direct despair- and hope-inducing messages (compared to a control condition involving a neutral message) on participants' experience of hope for peace, their sense of urgency to resolve the conflict, and subsequently their support for concession-making as a function of political orientation. Two samples of Jewish-Israelis were collected. Study 1 was collected using snowball methods, while Study 2 replicated and enhanced findings with a more representative sample of Jewish-Israeli society collected using an online survey platform. In both studies, messages of hope or despair yielded no influence on Rightists, whose baseline of hope is inherently low. However, for Leftists (experiencing higher levels of hope for peace) the despair manipulation significantly decreased support for concession-making through decreased hope for peace and sense of urgency to resolve the conflict, providing an explanation to the prevalence of despair over hope in conflict.     

"I" Value Freedom, But "We" Value Relationships: Self-Construal Priming Mirrors Cultural Differences in Judgment

The distinction between relatively independent versus interdependent self-construals has been strongly associated with several important cultural differences in social behavior. The current studies examined the causal role of self-construal by investigating whether priming independent or interdependent self-construals within a culture could result in differences in psychological worldview that mirror those traditionally found between cultures. In Experiment 1, European-American participants primed with interdependence displayed shifts toward more collectivist social values and judgments that were mediated by corresponding shifts in self-construal. In Experiment 2, this effect was extended by priming students from the United States and Hong Kong with primes that were consistent and inconsistent with their predominant cultural worldview. Students who received the inconsistent primes were more strongly affected than those who received the consistent primes, and thus shifted self-construal, and corresponding values, to a greater degree.     

Multi-wave Prospective Examination of the Stress-Reactivity Extension of Response Styles Theory of Depression in High-Risk Children and Early Adolescents

The current study tested the stress-reactivity extension of response styles theory of depression (Nolen-Hoeksema Journal of Abnormal Psychology 100:569–582, 1991) in a sample of high-risk children and early adolescents from a vulnerability-stress perspective using a multi-wave longitudinal design. In addition, we examined whether obtained results varied as a function of either age or sex. During an initial assessment, 56 high-risk children (offspring of depressed parents; ages 7–14) completed measures assessing rumination and depressive symptoms. Children were subsequently given a handheld personal computer which signalled them to complete measures assessing depressive symptoms and negative events at six randomly selected times over an 8-week follow-up interval. In line with hypotheses, higher levels of rumination were associated with prospective elevations in depressive symptoms following the occurrence of negative events. Sex, but not age, moderated this association. Rumination was more strongly associated with elevations in depressive symptoms following the occurrence of negative events in girls than in boys.
