Do I belong?: it depends on when you ask

A feeling of belonging to an academic context is a critical determinant of academic achievement and persistence, particularly for students of color. Despite the fact that students of color are generally more susceptible to fluctuations in belonging uncertainty than White students, survey design can unintentionally mask this reality. We investigated whether context effects undermine the accurate assessment of belonging uncertainty in junior high and high school students (Study 1) and college students (Study 2). Considering one's ethnic identification (Study 1) and personal experiences with discrimination (Study 2) threatens sense of belonging in students of color, but not White students. Researchers should consider question order within surveys so as not to artificially mask belonging uncertainty in students of color.     

The experience of altered states of consciousness in shamanic ritual: The role of pre-existing beliefs and affective factors

Much attention has been paid recently to the role of anomalous experiences in the aetiology of certain types of psychopathology, e.g. in the formation of delusions. We examine, instead, the top-down influence of pre-existing beliefs and affective factors in shaping an individual’s characterisation of anomalous sensory experiences. Specifically we investigated the effects of paranormal beliefs and alexithymia in determining the intensity and quality of an altered state of consciousness (ASC). Fifty five participants took part in a sweat lodge ceremony, a traditional shamanic ritual which was unfamiliar to them. Participants reported significant alterations in their state of consciousness, quantified using the ‘APZ’ questionnaire, a standardized measure of ASC experience. Participants endorsing paranormal beliefs compatible with shamanic mythology, and those showing difficulty identifying feelings scored higher on positive dimensions of ASC experience. Our findings demonstrate that variation in an individual’s characterisation of anomalous experiences is nuanced by pre-existing beliefs and affective factors.     

The long and short of it: physical anchoring effects

Attempts to reconstruct the magnitude of recently encountered physical stimuli were influenced by the provision of physical anchors. Whether estimating length, weight, or loudness, those increasing the magnitude of a relatively small (short, light, or quiet) physical anchor produced estimates that were reliably lower than did those decreasing the magnitude of a relatively large (long, heavy, or loud) anchor. Estimates produced without an anchor were also low, suggesting that when people physically adjust upwards from a self‐selected starting point, “no anchor” may, in fact, act as a very low anchor. Physical anchors appear to influence estimates of recently encountered physical stimuli, much as numerical anchors influence estimates of more abstract numerical quantities. Implications for processes underlying anchoring, adjustment, and related tasks are discussed. Copyright © 2006 John Wiley & Sons, Ltd.     

Anger After Childbirth: An Overlooked Reaction To Postpartum Stressors

Other than postpartum depression, little is known about women's emotional responses to childbirth and subsequent stressors. Anger was explored on the basis of theory and evidence that it is a likely emotional response in this context. During their third trimester of pregnancy and approximately six weeks after delivery, 163 participants completed the Beck Depression Inventory and the anger subset of the Affect Balance Scale. A number of childbirth–relevant variables were examined as predictors of postpartum emotional response, controlling for prepartum levels and for the association between anger and depressed mood. As expected, a substantial group of women reported high levels of anger irrespective of depressed mood. Although the majority of variables predicted depressed mood, childcare stress, age, and religious self–identification were independently predictive of postpartum anger (all p values > .05). Implications for research and clinical intervention are discussed.

Sociocultural developmental approaches to autobiographical memory

The sociocultural developmental model of autobiographical memory development has been a highly generative theoretical framework over the past 30 years, garnering both a great deal of empirical attention and support. In this article, the author details the theoretical framework and reviews the empirical evidence that indicates that individual differences in maternal reminiscing style has profound and enduring implications for the development of autobiographical memory. Concurrent, longitudinal, and experimental intervention research has demonstrated that mothers who reminisce in more highly elaborated ways with their preschool children facilitate the development of more elaborate and coherent autobiographical memories.

Obsessive-compulsive disorder subtypes: an attempted replication and extension of a symptom-based taxonomy

A symptom-based subgroup taxonomy for obsessive-compulsive disorder (OCD) was evaluated and refined. The Yale-Brown Obsessive-Compulsive Scale symptom checklist was scored and cluster analysis was conducted with a sample of OCD patients (N = 114). Results were compared to Calamari et al.'s (Behaviour Research and Therapy 37 (1999) 113) five subgroup model. Rules for determining the number of subgroups supported a more complex model. In between sample comparisons, a stable contamination subgroup was found in both a five and seven subgroup taxonomy. Between sample stability was not as strong for Harming, Obsessionals, Symmetry, and Certainty subgroups. Hoarding, as a distinctive subgroup, was unstable in separate samples. When the Calamari et al. sample and the present sample were combined (N = 220), we found a reliable Hoarding subgroup. More interpretable and stable models emerged with the combined samples suggesting that large clinical samples are needed to identify OCD subgroups. Greater support was found for a seven subgroup taxonomy based subgroup interpretability and validation measure differences. The potential utility of symptom-based subgroup models of OCD and alternative approaches are discussed. Identification of reliable and valid OCD subtypes may advance theory and treatment.     

Dissociated developmental trajectories for semantic and phonological false memories

False recognition following presentation of semantically related and phonologically related word lists was evaluated in 8-, 11-, and 13-year-olds. Children heard lists of words that were either semantic (e.g., bed, rest, wake ...) or phonological associates (e.g., pole, bowl, hole ...) of a critical unpresented word (e.g., sleep, roll), respectively. A semantic false memory was defined as false recognition of a semantically related but unpresented word. A phonological false memory was defined as false recognition of a phonologically related but unpresented word. False memories in the two tasks showed opposite developmental trends, increasing with age for semantic relatedness and decreasing with age for phonological relatedness.     

Family narrative interaction and children's sense of self

Family narratives about the shared past may be a particularly significant site for preadolescents' emerging sense of self both as an individual and as a member of a unified family. We examined the relations between family narrative interaction style when reminiscing and preadolescents' sense of self. Results indicated three narrative interaction styles that describe the extent to which families discuss or fail to discuss their past in integrated and validating ways. Specifically, conversations with a coordinated perspective incorporated information from all members and were related to higher self-esteem, especially in girls. Conversations with an individual perspective, in which family members took turns telling their thoughts and feelings about the event without integration among the perspectives, were associated with a more external locus of control, especially in boys. Conversations with an imposed perspective, in which one family member was in charge of the conversation or in which unpleasant exchanges between members occurred, were not associated with either self-esteem or locus of control. Implications of these narrative interaction styles for children's developing sense of self are discussed.
