Subtraction by addition

University students’ self-reports indicate that they often solve basic subtraction problems (13?6=?) by reference to the corresponding addition problem (6+7=13; therefore, 13?6=7). In this case, solution latency should be faster with subtraction problems presented in addition format (6+_=13) than in standard subtraction format (13+6=_). In Experiment 1, the addition format resembled the standard layout for addition with the sum on the right (6+_=13), whereas in Experiment 2, the addition format resembled subtraction with the minuend on the left (13=6+_). Both experiments demonstrated a latency advantage for large problems (minuend > 10) in the addition format as compared with the subtraction format (13+6=_), although the effect was larger in Experiment 1 (254 msec) than in Experiment 2 (125 msec). Small subtractions (minuend ≤ 10) in Experiment 1 were solved equally quickly in the subtraction or addition format, but in Experiment 2, performance on small problems was faster in the standard format (5?3=_) than in the addition format (5=3+_). The results indicate that educated adults often use addition reference to solve large simple subtraction problems, but that they rely on direct memory retrieval for small subtractions.     

Self-Other Perspective and Sexual Attitudes Affect Estimates of Sexual Risk

This study evaluated the effects of self-other perspective, sexual attitudes, and a sexual victimization history on women’s estimates of sexual risk for a set of vignettes describing situations that they may face when interacting socially with men. One hundred and twenty-four women from a medium sized southwestern university in the US were assigned to two different conditions (imagine self vs. an anonymous woman) and asked to rate how risky the situations described were in terms of having an unwanted sexual experience. Results revealed that participants asked to imagine an anonymous woman estimated sexual risk as higher than participants asked to imagine themselves, and that participants reporting liberal sexual attitudes estimated sexual risk as lower than participants reporting more conservative attitudes.     

Religious Fundamentalism as Schema: Influences on Memory for Religious Information

Those with differing levels of religious fundamentalism (RF) may be selective in their memory for religious information. In Study 1, participants read a text about money or sex, with a judgmental or not-judgmental message. Higher RF was associated with more accurate recall and fewer intrusions. In Study 2, participants high or low in RF read texts about sex. High-RF participants had more accurate recall and fewer intrusions. However, high-RF participants had more recognition false alarms to sentences that were not presented. High RF may aid memory for religious information, but also increase familiarity of related but not presented information. Exposure to not-judgmental messages decreased RF scores, suggesting that textual messages can impact responses to fundamentalism scales.     

Identity as a moderator of gender differences in the emotional closeness of emerging adults' same- and cross-sex friendships

Closeness is an integral aspect of friendships, and males and females differ in their closeness experiences within these relationships. However, identity development and friendship type (e.g., same-sex versus cross-sex friendships) may moderate these gender differences. In an attempt to clarify the relationships among gender, identity, and friendship closeness, the current study examined gender and identity associations with reported emotional closeness in emerging adults' same- and cross-sex friendships. Responses from 181 college undergraduates (89 males and 92 females) indicated similar levels of emotional closeness reported for same- and cross-sex friendships. Results also indicated overall identity commitment and friendship identity commitment associations with same-sex friendship closeness. Examination of closeness reports for cross-sex friends revealed a significant association with overall identity commitment for emerging adult males. A significant association was not indicated for emerging adult females. The associations between identity and emotional closeness in same-sex friendships and male cross-sex friendships support previous studies that report differences in the role of these relationships for emerging adult males and females. Findings are discussed in terms of understanding the gender and identity differences in emerging adults' reports of friendship closeness.     

Parenting styles or practices? Parenting, sympathy, and prosocial behaviors among adolescents

In the present study, the authors examined the relations among parenting styles, parental practices, sympathy, and prosocial behaviors in adolescents. The participants were 233 adolescents (M age = 16.7 years; 69% girls; mostly White) from public high schools in the Midwestern region of the United States who completed measures of prosocial behaviors, parenting styles, parenting practices, and sympathy. Overall, the authors found evidence that parenting practices were significantly associated with adolescents' prosocial behaviors. However, the associations between parenting practices and prosocial behaviors occurred mostly through the indirect relations with sympathy. The relations among parenting practices, sympathy, and prosocial behaviors varied as a function of the specific parenting practice and the specific prosocial behavior. Implications for future research on the study of prosocial development and parenting among adolescents are discussed.     

Varieties of grapheme-colour synaesthesia: a new theory of phenomenological and behavioural differences

Recent research has suggested that not all grapheme-colour synaesthetes are alike. One suggestion is that they can be divided, phenomenologically, in terms of whether the colours are experienced in external or internal space (projector–associator distinction). Another suggestion is that they can be divided according to whether it is the perceptual or conceptual attributes of a stimulus that is critical (higher–lower distinction). This study compares the behavioural performance of 7 projector and 7 associator synaesthetes. We demonstrate that this distinction does not map on to behavioural traits expected from the higher–lower distinction. We replicate previous research showing that projectors are faster at naming their synaesthetic colours than veridical colours, and that associators show the reverse profile. Synaesthetes who project colours into external space but not on to the surface of the grapheme behave like associators on this task. In a second task, graphemes presented briefly in the periphery are more likely to elicit reports of colour in projectors than associators, but the colours only tend to be accurate when the grapheme itself is also accurately identified. We propose an alternative model of individual differences in grapheme-colour synaesthesia that emphasises the role of different spatial reference frames in synaesthetic perception. In doing so, we attempt to bring the synaesthesia literature closer to current models of non-synaesthetic perception, attention and binding.     

Team cognition in experienced command-and-control teams

Team cognition in experienced command-and-control teams is examined in an UAV (Uninhabited Aerial Vehicle) simulation. Five 3-person teams with experience working together in a command-and-control setting were compared to 10 inexperienced teams. Each team participated in five 40-min missions of a simulation in which interdependent team members control a UAV to take reconnaissance photos. Experienced teams exceeded performance of inexperienced teams, suggesting transfer of previous command-and-control experience. Compared to inexperienced teams, experienced teams had fewer errors on process-related training knowledge, superior team process ratings, and communications containing fewer coordination-related utterances. These findings support the view that team cognition emerges through the interactions of team members, that interactions distinguish high-performing teams from average teams, and that these interactions transfer across different tasks.     

Adverse Housing Conditions and Early‐Onset Delinquency

Housing constitutes an important health resource for children. Research has revealed that, when housing conditions are unfavorable, they can interfere with child health, academic performance, and cognition. Little to no research, however, has considered whether adverse housing conditions and early‐onset delinquency are significantly associated with one another. This study explores the associations between structural and non‐structural housing conditions and delinquent involvement during childhood. Data from the Fragile Families and Child Wellbeing Study (FFCWS) were employed in this study. Each adverse housing condition was significantly associated with early‐onset delinquency. Even so, disarray and deterioration were only significantly linked to early delinquent involvement in the presence of health/safety hazards. The predicted probability of early‐onset delinquency among children exposed to housing risks in the presence of health/safety hazards was nearly three times as large as the predicted probability of early‐onset delinquency among children exposed only to disarray and/or deterioration, and nearly four times as large as the predicted probability of early‐onset delinquency among children exposed to none of the adverse housing conditions. The findings suggest that minimizing housing‐related health/safety hazards among at‐risk subsets of the population may help to alleviate other important public health concerns—particularly early‐onset delinquency. Addressing household health/safety hazards may represent a fruitful avenue for public health programs aimed at the prevention of early‐onset delinquency.
