Are memories for sexually traumatic events "special"? A within-subjects investigation of trauma and memory in a clinical sample

According to a long-standing clinical tradition, sexually traumatic experiences are processed and recalled differently from other experiences, often leading to memory impairment. In this study, we compared the characteristics of traumatic memories for sexual violence and two other types of emotional experiences. N=44 women recruited from a local sexual trauma agency were asked to recall and describe three autobiographical events: sexual abuse/assault, a non-sexual trauma, and a positive emotional event. The characteristics of the three memory types were compared on both subjective and objective measures. Further, the potential influences of level of traumatic impact and dissociation were assessed. Results indicated that memories for sexual trauma were not impaired or fragmented relative to other memories. Instead, memories for sexual trauma were associated with a remarkably high level of vividness, detail, and sensory components. Further, high levels of traumatic impact were not associated with memory impairment. Implications for the ongoing traumatic memory debate are discussed.     

Antecedents and consequences of reactions to developmental 360° feedback

This study investigated the factors that influence leaders’ reactions to 360° feedback and the relationship of feedback reactions to subsequent development activities and changes in leader behavior. For leaders with low ratings, those who agreed with others about their ratings were less motivated than those who received low ratings and over rated themselves. For leaders with high ratings, agreement between self and other did not influence their motivation. Individuals with more favorable attitudes toward using feedback were more motivated following feedback. We found minimal support for hypothesized relationships between personality characteristics and reactions to feedback. Leaders’ reactions to feedback were not related to the number of follow-up activities they reported, but were related to the degree of change in ratings over time.     

Ketamine as a primary predictor of out-of-body experiences associated with multiple substance use

Investigation of “out-of-body experiences” (OBEs) has implications for understanding both normal bodily-self integration and its vulnerabilities. Beyond reported associations between OBEs and specific brain regions, however, there have been few investigations of neurochemical systems relevant to OBEs. Ketamine, a drug used recreationally to achieve dissociative experiences, provides a real-world paradigm for investigating neurochemical effects. We investigate the strength of the association of OBEs and ketamine use relative to other common drugs of abuse. Self-report data (N = 192) from an online survey indicate that both lifetime frequency of ketamine use and OBEs during ketamine intoxication were more strongly related to the frequency of OBEs and related phenomena than other drugs. Moreover, the apparent effects of other drugs could largely be explained by associated ketamine use. The present results, consistent with the role of NMDA receptors in OBEs, should encourage future studies of the role of neurochemical systems in OBEs.     

The role of awareness in anticipation and recall performance in the Hebb repetition paradigm: implications for sequence learning

Sequence learning has notably been studied using the Hebb repetition paradigm (Hebb, 1961) and the serial reaction time (SRT) task (Nissen & Bullemer, Cognitive Psychology 19:1–32, 1987). These two paradigms produce robust learning effects but differ with regard to the role of awareness: Awareness does not affect learning a repeated sequence in the Hebb repetition paradigm, as is evidenced by recall performance, whereas in the SRT task, awareness helps to anticipate the location of the next stimulus. In this study, we examined the role of awareness in anticipation and recall performance, using the Hebb repetition paradigm. Eye movements were monitored during a spatial reconstruction task where participants had to memorize sequences of dot locations. One sequence was repeated every four trials. Results showed that recall performance for the repeated sequence improved across repetitions for all participants but that anticipation increased only for participants aware of the repetition.     

L’indépendance émotionnelle à la mère et au père en lien avec la détresse psychologique chez les jeunes femmes

Women aged from 18 to 25 years old are a group particularly at risk to experience elevated psychological distress. However, only a few studies have documented developmental factors associated with this variable for this population, especially in regard to emotional independence to mother's and father's individuation. The aim of the study is to explore the association between emotional independence to each parent, referring to the underlying emotional aspect related to the distance toward each parent, and psychological distress. The sample includes 1716 French-Canadian college women aged from 18 to 25 who completed an online survey. Results confirm the high prevalence of psychological distress among this population. Emotional independence to mothers and fathers are found to be moderately correlated. However, the mean emotional independence to mothers is significantly lower than the emotional independence to fathers. The results also suggest that low emotional independence, even to only one of parents is associated with higher levels of distress among young women. In contrast, levels of middle and high emotional independence from both parents are associated with lower levels of distress. The findings support the association between emotional independence to each parent and psychological distress. Empirically, further studies should distinguish between mother's and father's emotional independence. Clinically, these results emphasize the need to works patient's emotional independence to both parents.     

An Empiricist Conception of the Relation Between Metaphysics and Science

It is widely acknowledged that metaphysical assumptions, commitments and presuppositions play an important role in science. Yet according to the empiricist there is no place for metaphysics as traditionally understood in the scientific enterprise. In this paper I aim to take a first step towards reconciling these seemingly irreconcilable claims. In the first part of the paper I outline a conception of metaphysics and its relation to science that should be congenial to empiricists, motivated by van Fraassen’s work on ‘stances’. There has been a considerable about of recent work devoted to van Fraassen’s ‘stance’ view, but it has not on the whole been noticed that the view has the potential to motivate a general empiricist conception of the relation between science and metaphysics. In the second and third sections I discuss two examples from biology to illustrate this conception: metaphysical punctuationism, and its relation to and influence on the thesis of punctuated equilibrium; and dialectical biology as defended by Levins and Lewontin.

     

Spirituality and Self in Preadolescents: Implications for a connected curriculum

Drawing on recent studies of Canadian preadolescent girls and boys, this article considers how preadolescents' narratives can further our understanding of their spirituality and sense of self. This article reflects on how these often unheard voices might inform future research and education issues such as the role of teacher, pedagogy and curriculum. To bridge the divide between theory and practice, holistic educational activities based on promoting the connection among self (mind/body, emotion/cognition, rational/intuitive), community, and earth are outlined. The focus is on dialogue, connection, and the mutual co-creation of meaning.
