Sustained attention to a predictable,unengaging Go/No-Go task shows ongoing development between 6 and 11 years

Response time variability (RTV) is a useful measure of sustained attention; however, little is known about developmental changes in RTV at different temporal frequencies. Thirty-five 6-year-olds, 31 8-year-olds, and 37 10-year-olds completed the fixed-sequence Sustained Attention to Response Task on three occasions, six months apart. Fast Fourier Transform and ex-Gaussian analyses of response time (RT) data assessed momentary fluctuations in RT, gradual changes in RT, and very long responses, thought to reflect attentional control fluctuations, slow-shifting arousal, and infrequent lapses in attention, respectively. A half-by-half analysis measured within-occasion time-on-task effects. The 10-to 11-year-olds performed with less momentary fluctuations in RT, fewer long responses, and fewer commission and omission errors than the younger groups. This group performed well in the first half of the task but showed time-on-task effects on measures of momentary fluctuations in RT, very long responses, target sensitivity (d’), and commission errors. The 6- to 7-year-olds performed less well than the older groups, and showed time-on-task effects, on almost all measures. The 8- to- 9-year-olds mostly performed at an intermediate level compared with the other groups; however, this group performed with a similar level of momentary fluctuations in RT and very long responses as the 6- to 7-year-olds. These findings indicate that there is ongoing maturation of various aspects of sustained attention on a predictable task, with a period of relative stability in performance between 8 and 9 years of age.     

In‐group relevance facilitates learning across existing and new associations

Studies have shown that attention prioritizes stimuli associated with the in‐group. However, the extent to which this so‐called in‐group favoritism is driven by relevance is not clear. Here, we investigated this issue in a group of university rowers using a novel perceptual matching task based on the team label–color associations. Across three experiments, participants showed enhanced performance for the in‐group stimulus regardless of its familiarity level. These findings confirmed the role of relevance in in‐group favoritism. In a further control study, the advantage for certain stimuli was not found in an independent sample of participants who were not identified with the teams but were familiar with the label–color associations, indicating that in‐group relevance was necessary for the in‐group favoritism. Together, these findings suggest that in‐group relevance facilitates learning across existing and new associations. The consequences of these findings for understanding in‐group effects on perceptual processing are discussed.     

A Matter for Concern: Young Offenders and the Importance of Mattering

Adopting a case study approach, this research article aims to explore the concept of mattering as an alternative way of thinking about youth offending by drawing together the exploration of risk assessment practices within the context of criminal justice, alongside the exploration of the first-person accounts of young offenders’ experiences within the context of their everyday lives. Exploring conditions that influence young offenders’ perceptions of failing to matter, the article concludes by demonstrating that the need to matter becomes amplified when family is absent from a young person’s life.     

Substance use and violent behavior in women with antisocial personality disorder

The purpose of this study was to examine the relationship between substance abuse and dependence and violent behavior in a sample of incarcerated women with antisocial personality disorder (ASPD). Among male populations, substance dependence is associated with aggression and criminal behavior. Individuals with ASPD have more severe substance dependence, including higher symptom counts, earlier age of onset, and more frequent co-morbidity. Incarcerated women have a high prevalence of ASPD and substance dependence, but there has been little detailed work regarding addiction severity. Similarly, work on association of substance abuse and dependence with specific violent behaviors has been limited. This study examined a group of 41 mid-sentence female felons with a diagnosis of ASPD to determine associations with substance abuse and dependence. Data were gathered through administration of the Semi-Structured Assessment of the Genetics of Alcoholism II (SSAGA II). Substance dependence was highly prevalent (i.e., alcohol dependence, 56.1%; opiate dependence, 48.8%; cocaine dependence, 61.0%). While specific diagnoses were not associated with violent behavior and offending, symptom severity (i.e., age of onset, symptom count, co-morbidity) was associated with violent behavior in women dependent on opiates, alcohol, and cocaine. Arrest for an assault 1 was associated with alcohol dependence and opiate dependence. These data suggest that measurement of symptom severity and co-morbidity is important in assessing violent behavior in incarcerated women with ASPD. These findings are potentially important in examining non-incarcerated, substance-dependent women.     

Factor Structure of the Pediatric Symptom Checklist with a Pediatric Gastroenterology Sample

Pediatric gastrointestinal disorders are commonly experienced by youth and have been shown to be associated with increased rates of psychosocial difficulties. Aim of the current study was to extend development of the Pediatric Symptom Checklist (PSC), a brief parent-completed measure designed to assess children’s behavioral and emotional functioning, by examining its factor structure in a pediatric gastroenterology sample. Parents of 176 children ages 4–16 years visiting a pediatric gastroenterologist completed the PSC. The factor structure of the PSC was examined using principal component analysis. Parallel analysis was utilized to determine the number of factors to retain and indicated that three factors existed within the data. A principal component analysis with varimax rotation identified factors measuring internalizing, externalizing, and attention difficulties. The three factors that emerged on the PSC provide initial support for the utility of the PSC in pediatric gastroenterology clinics.     

Friends with benefits: the evolved psychology of same- and opposite-sex friendship

During human evolution, men and women faced distinct adaptive problems, including pregnancy, hunting, childcare, and warfare. Due to these sex-linked adaptive problems, natural selection would have favored psychological mechanisms that oriented men and women toward forming friendships with individuals possessing characteristics valuable for solving these problems. The current study explored sex-differentiated friend preferences and the psychological design features of same- and opposite-sex friendship in two tasks. In Task 1, participants (N = 121) categorized their same-sex friends (SSFs) and opposite-sex friends (OSFs) according to the functions these friends serve in their lives. In Task 2, participants designed their ideal SSFs and OSFs using limited budgets that forced them to make trade-offs between the characteristics they desire in their friends. In Task 1, men, more than women, reported maintaining SSFs for functions related to athleticism and status enhancement and OSFs for mating opportunities. In Task 2, both sexes prioritized agreeableness and dependability in their ideal SSFs, but men prioritized physical attractiveness in their OSFs, whereas women prioritized economic resources and physical prowess. These findings suggest that friend preferences may have evolved to solve ancestrally sex-linked adaptive problems, and that opposite-sex friendship may directly or indirectly serve mating functions.     

Divergent effects of different positive emotions on moral judgment

Positive emotions are often treated as relatively similar in their cognitive-behavioral effects, and as having unambiguously beneficial consequences. For example, Valdesolo and DeSteno (2006) reported that a humorous video made people more prone to choose a utilitarian solution to a moral dilemma. They attributed this finding to increased positive affect. To determine whether such results actually stem in general from positive affect or from other more specific properties of humor, we conducted an experiment with moral dilemmas presented during an interleaved emotion-induction procedure involving mirth and another positive emotion, elevation. Mirth increased permissiveness for deontological violations, whereas elevation had the opposite effect. Furthermore, affective valence had no apparent independent influence on these judgments. Our results suggest that mirth and elevation have distinct cognitive consequences whose properties reflect their respective social functions, not their shared positive valence.     

Perceptual organization without perception. The subliminal learning of global contour

A critical step in visual perceptual processing is integrating local visual elements into contours so that shapes can be derived from them. It is often assumed that contour integration may reflect hardwired coding of low-level visual features. In this study, we present novel evidence indicating that integration of local elements into contours can be learned subliminally, despite being irrelevant to the training task and despite the local properties of the display varying randomly during training. Learning occurred only when contours were consistently paired with task-relevant targets--echoing the findings of previous studies on subliminal learning of low-level features. Our data indicate that task-irrelevant, exposure-based learning extends beyond local low-level visual features and may play a critical role at multiple levels of visual perceptual organization.
