Coding modality vs. input modality in hypermnesia: Is a rose a rose a rose?

Recent experiments indicate that recall of pictures, unlike recall of words, may increase (hypermnesia) with time and effort. This study demonstrates that by recoding word inputs into ‘mental pictures’, i.e., images, subjects can transform inert word lists into hypermnesic ones. Thus, when word inputs are recoded into images, recall increases over time, and resembles in other respects the recall of pictures.     

The missing link? Testing a schema account of unitization

Unitization refers to the creation of a new unit from previously distinct items. The concept of unitization has been used to explain how novel pairings between items can be remembered without requiring recollection, by virtue of new, item-like representations that enable familiarity-based retrieval. We tested an alternative account of unitization – a schema account – which suggests that associations between items can be rapidly assimilated into a schema. We used a common operationalization of “unitization” as the difference between two unrelated words being linked by a definition, relative to two words being linked by a sentence, during an initial study phase. During the following relearning phase, a studied word was re-paired with a new word, either related or unrelated to the original associate from study. In a final test phase, memory for the relearned associations was tested. We hypothesized that, if unitized representations act like schemas, then we would observe some generalization to related words, such that memory would be better in the definition than sentence condition for related words, but not for unrelated words. Contrary to the schema hypothesis, evidence favored the null hypothesis of no difference between definition and sentence conditions for related words (Experiment 1), even when each cue was associated with multiple associates, indicating that the associations can be generalized (Experiment 2), or when the schematic information was explicitly re-activated during Relearning (Experiment 3). These results suggest that unitized associations do not generalize to accommodate new information, and therefore provide evidence against the schema account.     

Getting a Life: Gender Differences in Postwar Recovery

This study examined gender differences in stress symptoms and recovery one year after the end of war, among two Israeli samples (adults n?=?870 and adolescents n?=?810). MANOVA analysis indicated that females reported higher levels of stress symptoms and lower levels of postwar recovery compared to males. Adolescents reported lower levels of stress and higher levels of recovery compared to adults. Path analysis supported the following: Gender associated negatively with family support and sense of danger. Sense of danger associated positively with symptoms and negatively with recovery, while family support associated with these variables in the opposite direction. Mediation test indicated that family support and sense of danger served as mediators between gender and recovery and between gender and stress symptoms.     

Exploring negative emotion in women experiencing intimate partner violence: shame, guilt, and PTSD

This study explored the association of shame and guilt with PTSD among women who had experienced intimate partner violence (IPV). Sixty-three women were assessed by a research clinic serving the mental health needs of women IPV survivors. Results indicated that shame, guilt-related distress, and guilt-related cognitions showed significant associations with PTSD but global guilt did not. When shame and guilt were examined in the context of specific forms of psychological abuse, moderation analyses indicated that high levels of both emotional/verbal abuse and dominance/isolation interacted with high levels of shame in their association with PTSD. Neither guilt-related distress nor guilt-related cognitions were moderated by specific forms of psychological abuse in their association with PTSD. These data support the conceptualization of shame, guilt distress, and guilt cognitions as relevant features of PTSD. Results are discussed in light of proposed changes to diagnostic criteria for PTSD.
