Dissociative tendencies and memory performance on directed-forgetting tasks

The current article presents two studies that aimed to replicate DePrince and Freyd's (2001, 2004) studies demonstrating that high and low dissociators differentially recall neutral and trauma words under conditions of varying cognitive load. We did not find this effect. This lack of replication was apparent for both free recall and word recognition memory and in both studies. In effect, we found little evidence to support betrayal trauma theory, yet observed increased memory fallibility, as demonstrated by lower general recall and (in one study) commission errors, in high dissociators.     

Better the DVL you know: acronyms reveal the contribution of familiarity to single-word reading

Current theories of reading are divided between dual-route accounts, which propose that separable processes subserve word recognition for orthographically regular and irregular strings, and connectionist models, which propose a single mechanism mapping form to meaning. These theories make distinct predictions about the processing of acronyms, which can be orthographically illegal and yet familiar, as compared with the processing of pseudowords, which are regular but unfamiliar. This study examined whether acronyms are processed like pseudowords and words. Event-related potentials (ERPs) were recorded as subjects viewed familiar and unfamiliar acronyms, words, pseudowords, illegal strings, and--as the targets of the substantive behavioral task--proper names. Familiar acronyms elicited repetition effects on the N400 component, a functionally specific index of semantic activation processes; repetition effects for familiar acronyms were similar in magnitude, timing, and scalp distribution to those for words and pseudowords. The similarity of the brain response to familiar--but--illegal and unfamiliar--but--legal classes of stimuli is inconsistent with predictions of dual-route models of reading.     

Self-ordered pointing as a test of working memory in typically developing children

The self-ordered pointing test (SOPT; Petrides & Milner, 1982) is a test of non-spatial executive working memory requiring the ability to generate and monitor a sequence of responses. Although used with developmental clinical populations there are few normative data against which to compare atypical performance. Typically developing children (5-11 years) and young adults performed two versions of the SOPT, one using pictures of familiar objects and the other hard-to-verbalise abstract designs. Performance improved with age but the children did not reach adult levels of performance. Participants of all ages found the object condition easier than the abstract condition, suggesting that verbal processes are utilised by the SOPT. However, performance on the task was largely independent from verbal and nonverbal cognitive ability. Overall the results suggest that the SOPT is a sensitive measure of executive working memory.     

The Impact of Breast Cancer Genetic Risk Assessment on Intentions to Perform Cancer Surveillance Behaviors

One hundred and fifty-four women undergoing breast/ovarian cancer genetic risk assessment completed questionnaires at entry into the Cancer Genetic Service for Wales (CGSW) assessment program and following risk provision, mapping the strength of intentions to engage in a number of preventive/surveillance behaviors, including seeing specialists, breast self-examination, and involvement in screening programs, including mammography. A number of potential predictors of intentions were also assessed, including participants' mood and emotional response to receiving risk information, the perceived benefits (in terms of reassurance and early disease detection) of engaging in each preventive behavior, and the perceived desires of their family and General Practitioner. Intentions to self-examine did not change following risk provision, although strength of intentions to engage in some other preventive behaviors did lessen. Family and General Practitioners appeared to be strong social influences on behavioral intentions, as were the perceived benefits of gaining reassurance and/or early detection of disease.     

Satisfactions and Regrets of Midlife Parents: A Qualitative Analysis

The study examined the satisfactions and regrets of midlife parents at a specific family life-cycle milestone, their child’s graduation from high school. The purpose was to compare mothers’ and fathers’ appraisals of the gains and losses associated with this developmental transition and turning point in their parenting roles. A total of 260 parents (147 mothers; 113 fathers) who had a child graduating from high school responded in writing to open-ended questions regarding their satisfactions and regrets at this stage of their lives. Responses were coded to identify themes salient to these parents. Results indicate that both mothers and fathers are aware of both the gains and losses at this time in their family life cycle, but they differed in how they expect to be affected by the transition. Mothers’ responses suggest that they are anticipating and planning for the transition. Fathers’ responses suggest they are less aware of the personal implications of this family transition and are less prepared for its emotional impact.     

The acronym superiority effect

The visual world is replete with noisy, continuous, perceptually variant linguistic information, which fluent readers rapidly translate from percept to meaning. What are the properties the language comprehension system uses as cues to initiate lexical/semantic access in response to some, but not all, orthographic strings? In the behavioral, electromagnetic, and neuropsychological literatures, orthographic regularity and familiarity have been identified as critical factors. Here, we present a study in the Reicher—Wheeler tradition that manipulates these two properties independently through the use of four stimulus categories: familiar and orthographically regular words, unfamiliar but regular pseudowords, unfamiliar illegal strings, and familiar but orthographically illegal acronyms. We find that, like letters in words and pseudowords, letters in acronyms enjoy an identification benefit relative to similarly illegal, but unfamiliar strings. This supports theories of visual word recognition in which familiarity, rather than orthographic regularity, plays a critical role in gating processing.     

On the validity and utility of discriminating among impulsivity-like traits

The ability to make precise distinctions among related personality constructs helps clarify theory and increases the utility of clinical assessment. In three studies, the authors evaluated the validity of distinctions among four impulsivity-like traits: sensation seeking, lack of planning, lack of persistence, and urgency (acting rashly when distressed). Factor analyses indicated that lack of planning and lack of persistence are two distinct facets of one broader trait, whereas urgency and sensation seeking are both very modestly related to each other and to the planning/persistence measures. The authors developed interview assessments of each, and multitrait, multimethod matrix results indicated clear convergent and discriminant validity among the constructs. The distinctions among them were useful: The traits accounted for different aspects of risky behaviors. Sensation seeking appeared to relate to the frequency of engaging in risky behaviors, and urgency appeared to relate to problem levels of involvement in those behaviors.     

College dating and social anxiety: using the Internet as a means of connecting to others.

With the advent and widespread use of the Internet, various online media are being used to connect and maintain social relationships in individuals of all ages. Social relationships are vital to healthy development, and individuals with social and/or dating anxiety may have marked difficulty in establishing appropriate, supportive relationships because of fear of negative evaluation by others. For these individuals, the Internet may open avenues of communication and provide an outlet through which relationships can be formed and preserved. This study investigated the characteristics of computer and Internet use in young adults to determine whether individuals who were high in social/dating anxiety symptoms were more likely to make and maintain social relationships online. To further understand the patterns of these behaviors, several measures of social and dating anxiety were collected and analyzed along with demographic, computer use, and relationship characteristics. Results indicated differences between high and low social/dating anxiety with respect to media use and relationship formation. Limitations and future directions are discussed.     

Ethnic variation in depressive symptoms in a community sample in Hawaii

A modified CES-D was administered to a community sample of 176 European Americans (EA), 209 Native Hawaiians (NH), and 357 Japanese Americans (JA), yielding measures of depression, positive affect, depressed affect, somatic disturbance, and disturbed interpersonal relations. Positive affect was lower in JA relative to EA, consistent with findings among Native Japanese, a pattern attributed to cultural variation in emotion regulation. NH reported lower positive affect than EA, accompanied by elevated negative affect and somatic disturbance, suggesting generally higher levels of depressive symptoms. The three ethnic groups varied in mental health care usage with differing associations between depressive symptoms and experiences of stressful life events. Taken together, these results suggest ethnic variation in depressive symptoms may arise from differing cultural beliefs.     

Classifying chimpanzee facial expressions using muscle action

The Chimpanzee Facial Action Coding System (ChimpFACS) is an objective, standardized observational tool for measuring facial movement in chimpanzees based on the well-known human Facial Action Coding System (FACS; P. Ekman & W. V. Friesen, 1978). This tool enables direct structural comparisons of facial expressions between humans and chimpanzees in terms of their common underlying musculature. Here the authors provide data on the first application of the ChimpFACS to validate existing categories of chimpanzee facial expressions using discriminant functions analyses. The ChimpFACS validated most existing expression categories (6 of 9) and, where the predicted group memberships were poor, the authors discuss potential problems with ChimpFACS and/or existing categorizations. The authors also report the prototypical movement configurations associated with these 6 expression categories. For all expressions, unique combinations of muscle movements were identified, and these are illustrated as peak intensity prototypical expression configurations. Finally, the authors suggest a potential homology between these prototypical chimpanzee expressions and human expressions based on structural similarities. These results contribute to our understanding of the evolution of emotional communication by suggesting several structural homologies between the facial expressions of chimpanzees and humans and facilitating future research.
