The effects of noise and gender on children's episodic and semantic memory

The main objectives in the present study were to examine meaningful irrelevant speech and road traffic noise effects on episodic and semantic memory, and to evaluate whether gender differences in memory performance interact with noise. A total of 96 subjects, aged 13-14 years (n = 16 boys and 16 girls in each of three groups), were randomly assigned to a silent or two noise conditions. Noise effects found were restricted to impairments from meaningful irrelevant speech on recognition and cued recall of a text in episodic memory and of word comprehension in semantic memory. The obtained noise effect suggests that the meaning of the speech were processed semantically by the pupils, which reduced their ability to comprehend a text that also involved processing of meaning. Meaningful irrelevant speech was also assumed to cause a poorer access to the knowledge base in semantic memory. Girls outperformed boys in episodic and semantic memory materials, but these differences did not interact with noise.     

The effects of road traffic noise and meaningful irrelevant speech on different memory systems

To explore why noise has reliable effects on delayed recall in a certain text-reading task, this episodic memory task was employed with other memory tests in a study of road traffic noise and meaningful but irrelevant speech. Context-dependent memory was tested and self-reports of affect were taken. Participants were 96 high school students. The results showed that both road traffic noise and meaningful irrelevant speech impaired recall of the text. Retrieval in noise from semantic memory was also impaired. Attention was impaired by both noise sources, but attention did not mediate the noise effects on episodic memory. Recognition was not affected by noise. Context-dependent memory was not shown. The lack of mediation by attention, and road traffic noise being as harmful as meaningful irrelevant speech, are discussed in relation to where in the input/storing/output sequence noise has its effect and what the distinctive feature of the disturbing noise is.     

Unpacking the Role of Conflict in Peer Relationships: Implications for Peer Deviance and Crime

ABSTRACT

Although criminologists have long recognized the role that peers play in crime, the specific mechanisms responsible for this relationship have been difficult to isolate. Drawing from the perspectives of differential coercion and social support and differential association, we examine how one type of coercion among friends – conflict – moderates the peer deviance/crime relationship. Using dyadic data, greater levels of conflict are related to higher levels of deviance and conflict weakens the peer deviance–crime relationship. Overall, conflict plays a dual role by relating to higher amounts of deviance while jointly reducing the influence of peer deviance on crime.     

The Implications of Using Group-Based Offenses versus Non-Group-Based Offenses in Peer Deviance Scales

A key distinction from Warr’s research is “groupy” (deviant acts commonly committed with peers) versus “non-groupy” (acts that are likely committed alone) deviance. Drawing on Warr’s important (and underutilized) distinction, this study’s goal is to determine whether measures of perceptual groupy peer deviance more accurately reflect a peer’s true deviance than perceptions of nongroupy peer deviance. Using dyadic data, results demonstrate that perceptions of a peer’s non-groupy deviance are largely inaccurate but perceptions of a peer’s groupy deviance are quite accurate. Despite this discrepancy, groupy and non-groupy perceptual measures function similarly in multivariate models and consistently outperform peer self-reports.     

On the validity of remember-know judgments: evidence from think aloud protocols

The use of remember–know judgments to assess subjective experience associated with memory retrieval, or as measures of recollection and familiarity processes, has been controversial. In the current study we had participants think aloud during study and provide verbal reports at test for remember–know and confidence (i.e., sure–probably) judgments. Results indicated that the vast majority of remember judgments for studied items were associated with recollection from study (87%), but this correspondence was less likely for high-confidence judgments (72%). Instead, high-confidence judgments were more likely than remember judgments to be associated with incorrect recollection and a lack of recollection. Know judgments were typically associated with a lack of recollection (62%), but still included recollection from the study context (33%). Thus, although remember judgments provided fairly accurate assessments of retrieval including contextual details, know judgments did not provide accurate assessments of retrieval lacking contextual details.     

Personality traits in women with Turner syndrome

Turner syndrome is caused by the total or partial absence of, or structural abnormalities in, one sex chromosome. A personality style characterized by traits related to low neuroticism and high extroversion has been reported for females with Turner syndrome, indicating possible genetic factors related to personality development. This study examines personality traits in 37 Swedish women with Turner syndrome using the Karolinska Scales of Personality Inventory. Compared to reference data, the subjects rated themselves as more sensation seeking, less detached, less verbally aggressive and less irritated. These results partially support previous findings. The subjects were divided into three karyotype groups: 45,X (n = 13), 45,X/46,XX or 45,X/45,XY (n = 13), and structural abnormalities (n = 11). Contrary to some previous findings, no differences in personality were found between the karyotype groups.     

Cross-Validation of the Behavioral and Emotional Rating Scale-2 Youth Version: An Exploration of Strength-Based Latent Traits

High-quality measurement is a necessary requirement to develop and evaluate the effectiveness of programs that use strength-based principles and strategies. Using independent cross-validation samples, we report two studies that explored the construct validity of the BERS-2 Youth Report, a popular measure designed to assess youth strengths, whose conceptual structure has not yet been examined. In Study 1, an exploratory factor analysis found a four-factor solution with conceptual support, which included both internal assets associated with (a) the management of emotions and positive social interaction skills and (b) engagement in the important social contexts of family and school. In Study 2, confirmatory factor analyses found reasonable model fit for the BERS-2 five-factor structure and superior model fit for the more parsimonious four-factor solution found in Study 1. In future studies, parallel reporting of the four-factor model may provide additional insight to the nature and structure of the BERS-2 Youth Version’s clinical validity and utility when compared with the five-factor model, thus potentially contributing to a broader objective to develop a better understanding of important strength-based latent traits.
