Action planning in the presence of distracting stimuli: an investigation into the time course of distractor effects

Humans have a remarkable capability to respond efficiently to a stimulus of interest despite other stimuli competing for neural resources. The current study investigated how the human system copes with distracting stimuli. During each trial, participants viewed 2 sequential stimuli that were each associated with a specific action based on an arbitrary mapping. The 1st stimulus served as a distractor, and the 2nd stimulus required a response (target). When the distractor preceded the target by more than a few hundred milliseconds, response latencies were slower when the 2 stimuli were associated with the same response. The authors propose that this negative compatibility effect stemmed from an inhibitory mechanism that the human system utilizes to prevent the distractor from eliciting an unwanted response.     

Construction and validation of the Intragroup Marginalization Inventory

This study reports the development and validation of the Intragroup Marginalization Inventory (IMI). The IMI consists of three scales that assess the extent to which an individual perceives interpersonal distancing from family, friends, and ethnic group community members. Intragroup marginalization is defined as the interpersonal distancing that occurs when an acculturating individual is believed to exhibit behaviors, values, and beliefs that are outside the heritage culture's group norms. Intragroup marginalization is based on social identity theory that asserts that groups maintain their identity by the distinctive behaviors of its members. When an acculturating individual displays behaviors or attitudes that differ from the heritage culture group's norms, the group may respond to the threat with social alienation of the transgressor. The results support the IMI's validity via a) content validity in the development of the items, b) construct validity in the selection of the factors based upon an exploratory factor analysis, c) the replicability of the factors based upon a confirmatory factor analysis, and d) discriminant validity through examining the relationship of the factors with other established measures.     

THE EFFECTS OF CHILDHOOD SEXUAL MESSAGES ON AFRICAN-AMERICAN AND WHITE WOMEN'S ADOLESCENT SEXUAL BEHAVIOR

To clarify the relationship between sexual communication and sexual behavior, multiple components of sexual messages recalled from child hood were examined in a community sample of 248 African-American and White women. Respondents were matched on a predesignated set of demographic variables and were interviewed using the Wyatt Sexual History Questionnaire. We anticipated that women's recollections of messages from parents and television would differ both individually and across ethnicity, and that messages recalled from parents would be multidimensional, varying in tone (positive vs. negative) across time (childhood vs. adolescence) and form (verbal vs. nonverbal). We also expected that the presence and tone of specific types of messages re called would be associated with risk-related sexual behavior. Results confirmed predictions concerning differential interpretations of messages, and ethnicity emerged as a strong mediating variable. The implications of the specific types of parental messages influencing behavior are discussed.     

JPSSM since the beginning: intellectual cornerstones,knowledge structure,and thematic developments

Bibliometric analyses are applied to 35,975 citations from 721 articles published in the Journal of Personal Selling & Sales Management, spanning the journal’s first 35 years of existence (1980–2015). For each of three time periods (1980s, 1990s, and 2000s), the sales literature’s most influential article publications are objectively identified. Multidimensional scaling is then used to identify key intellectual themes across time. Based on the citation data, historical developments in the literature regarding (1) relationship marketing, (2) sales force technology, (3) sales force control systems, and (4) salesperson role stress are traced and briefly explored in some article-level depth. Co-citation trends and recently influential papers are used to identify opportunities for future research. Altogether, this paper presents a first-of-its-kind view of sales literature’s intellectual cornerstones, knowledge structure, and thematic developments over 35 years.     

Parents’ Experiences of Receiving the Initial Positive Newborn Screening (NBS) Result for Cystic Fibrosis and Sickle Cell Disease

The clinical advantages of the newborn screening programme (NBS) in the UK are well described in the literature. However, there has been little exploration of the psychosocial impact on the family. This study followed the principles of grounded theory to explore parents’ experiences of receiving the initial positive NBS result for their child with cystic fibrosis (CF) or sickle cell disease (SCD). Semi-structured, qualitative interviews were conducted with 22 parents (12 mothers and 10 fathers) whose children had been diagnosed with CF or SCD via NBS and were under the age of 1 year at the time of interview. The main themes that arose from the data were; parents previous knowledge of the condition and the NBS programme, the method of delivery and parental reactions to the result, sharing the results with others, the impact on parental relationships and support strategies. Study conclusions indicate that most parents thought initial positive NBS results should be delivered by a health professional with condition specific knowledge, preferably with both parents present. Genetic counselling needs to include a focus on the impact of NBS results on parental relationships. Careful consideration needs to be given to strategies to support parents of babies who have positive NBS results both in terms of the psychological health and to assist them in sharing the diagnosis.     

Burnout,compassion fatigue and compassion satisfaction among nurses in the context of maternal and perinatal deaths

This study investigated the prevalence and levels of burnout, compassion fatigue and compassion satisfaction among nurses with exposure to maternal and perinatal deaths. A convenience sample of 83 nurses was selected for participation from six hospitals in Limpopo province, South Africa, comprising 98% females with an age range of 21 to 62 years, and 15 to 18 mean years of experience in maternal and perinatal care. The nurses completed the Professional Quality of Life Scale (ProQOL R-IV), which is a measure of burnout, compassion fatigue and compassion satisfaction. The analysis examined the prevalence and level of burnout, compassion fatigue and compassion satisfaction among the nurses. Most of the respondents (92%) reported with moderate burnout scores, and about 67% reported with moderate to high compassion fatigue scores, whilst 82% reported with compassion satisfaction scores. Moderate levels of high burnout and compassion fatigue can co-occur with relatively high compassion satisfaction among nurses in critical-care health services.     

How Do Logics Explain?

Anti-exceptionalists about logic maintain that it is continuous with the empirical sciences. Taking anti-exceptionalism for granted, we argue that traditional approaches to explanation are inadequate in the case of logic. We argue that Andrea Woody's functional analysis of explanation is a better fit with logical practice and accounts better for the explanatory role of logical theories.     

Refining the Preschool Self‐regulation Assessment for Use in Preschool Classrooms

To aid in understanding preschoolers' self‐regulation and refinement of measurement, we examined properties of a field‐based assessment battery of preschooler's self‐regulation, the Preschool Self‐regulation Assessment (PSRA). The PSRA, which includes seven age‐appropriate tasks that tap children's executive control, was administered to 313 preschoolers and then to 261 of these children approximately 3 months later. Teachers reported on children's school readiness (social competence and classroom adjustment) at the end of preschool and kindergarten years, and on academic success in kindergarten. PSRA tasks were examined for ceiling effects at 35–65 months; Pencil Tap, Balance Beam, Toy Wrap and Snack Delay were retained for lack of such effects. Confirmatory factor analyses showed two components at each time point – hot and cool executive control – and cross‐time correlations showed significant stability of individual differences. Four‐year‐old girls and children of higher socioeconomic status outperformed 3‐year‐old boys and those at socioeconomic risk. Children, especially girls, scored higher on hot executive control. Finally, aspects of executive control differentially predicted teacher‐reports of school readiness at both times of assessment, with age, gender and risk status controlled. These selected PSRA tasks, as a shortened battery, have potential for research and applied usage, and findings speak to theoretical understanding of preschoolers' self‐regulation.

Reminders can enhance or impair episodic memory updating: a memory-for-change perspective

ABSTRACT

The Memory-for-Change framework proposes that retrieving episodic memories can facilitate new learning when changes between existing memories and new information are integrated during encoding and later recollected. Four experiments examined whether reminders could improve memory updating and enhance new learning. Participants studied two study lists of word pairs and were given a cued recall test on responses from both lists. Reminders of List 1 words pairs (A-B) appeared immediately before List 2 words pairs that included repeated cues and changed responses (A-D). Across experiments, we varied the types of reminders to determine whether differences in their effectiveness as retrieval cues would influence memory for the list membership of responses. We found that presenting intact reminders (cue-response) enhanced the memory benefits associated with recollection-based retrieval of changes relative to when no reminders appeared and when partial reminders (cue-only) appeared with and without feedback. Importantly, cue-response reminders benefitted memory when they were recognised in List 2 and when changes were later recollected. This suggests that integrative encoding can be facilitated when substantial environmental support is available to cue retrieval of existing memories. These findings have practical implications for understanding which reminders best aid the correction of memories for inaccurate information.
