Adolescent aggression and social cognition in the context of personality: impulsivity as a moderator of predictions from social information processing

This study asked how individual differences in social cognition and personality interact in predicting later aggressive behavior. It was hypothesized that the relationship between immediate response evaluations in social information processing (SIP) and later aggressive behavior would be moderated by impulsivity. In particular, the immediate positive evaluations of aggressive responses would be more strongly related to later aggressive behavior for high-impulsive than for low-impulsive individuals, because high-impulsive children would be less likely to integrate peripheral information and consider long-term future consequences of their actions. Participants were 585 adolescents (52% male) and their mothers and teachers from the longitudinal Child Development Project. Structural equation modeling indicated that teacher-reported impulsivity at ages 11-13 moderated the association between adolescents' endorsement of aggressive responses in hypothetical, ambiguous situations and subsequent mother-reported aggressive behavior. Specifically, positive endorsement of aggressive responses at age 13 was significantly related to later aggressive behavior (age 14-17) for participants with high and medium levels of impulsivity, but this association was not significant for participants with low levels of impulsivity. This study provides evidence of personality variables as potential moderators of the link between SIP and behavior.     

Expertise and attunement to kinematic constraints

Three experiments were undertaken to ascertain the extent to which expertise in natural anticipatory tasks is characterised by superior attunement to the biomechanical (kinematic) constraints of the movement pattern being observed. Twelve world-class and twelve non-expert badminton players were required to predict the depth of an opponent's stroke from either video displays or point-light displays of the opposing player's hitting action. The information available within the displays was manipulated through temporal and/or spatial occlusion. Consistent with predictions that can be derived from the constraint-attunement hypothesis (Vicente and Wang, 1998 Psychological Review 105 33-57), experts showed: (i) an unchanged pattern of information pick-up when the display was reduced from video to point-light and only kinematic information was available; (ii) superior information pick-up from kinematic features that non-experts could use; and (iii) attunement to early kinematic information from the lower body to which non-experts were not sensitive. Consistent with predictions that can be derived from a common-coding perspective (Prinz, 1997 European Journal of Cognitive Psychology 9 129-154), the anticipation of stroke depth was facilitated more for experts than non-experts when the perceptual display provided linked segment information reminiscent of the cross-segmental torque transfers that occur during expert movement production.     

Inhibited and aggressive preschool children at 23 years of age: personality and social transitions into adulthood

In a 19-year longitudinal study, the 15% most inhibited and the 15% most aggressive children at ages 4-6 years were followed up until age 23 years and were compared with controls who were below average in preschool inhibition or aggressiveness. As adults, inhibited boys and girls were judged as inhibited by their parents and showed a delay in establishing a first stable partnership and finding a first full-time job. However, only the upper 8% in terms of inhibition tended to show internalizing problems, including self-rated inhibition. Aggressive boys showed an externalizing personality profile in the parental and self-judgments, were educational and occupational underachievers, and showed a higher adult delinquency rate than the controls, even after sex and socioeconomic status were controlled. The results suggest delayed social transitions without internalizing problems for most male and female inhibited children and a significant long-term risk of an externalizing profile for aggressive children.     

Panic-relevant predictability preferences: a laboratory test

In the present investigation the authors evaluated the role of verbally instructed safety periods as they relate to predictability preference within a single-session challenge paradigm involving recurrent administrations of 20% carbon dioxide (CO-sub-2) enriched air. Participants included 160 nonclinical young adults (91 women, 69 men) between the ages of 18 and 59 (M=21.6 years; SD=7.23). Results indicated that equivalent levels of anxiety were experienced during predictable and unpredictable administrations of 20% CO-sub-2, yet participants preferred predictable compared with unpredictable trials, with women showing a stronger predictability preference than men. Lower anxiety was reported during known safety periods (predictable room air trials) but not during predictable compared with unpredictable administrations of 20% CO-sub-2. Findings are discussed in relation to theoretical and applied implications for the role of predictability in the nature of anxiety and its disorders.     

A comparative study of the dimensionality of the self-concealment scale using principal components analysis and Mokken scale analysis

We discuss and contrast 2 methods for investigating the dimensionality of data from tests and questionnaires: the popular principal components analysis (PCA) and the more recent Mokken scale analysis (MSA; Mokken, 1971). First, we discuss the theoretical similarities and differences between both methods. Then, we use both methods to analyze data collected by means of Larson and Chastain's (1990) Self-Concealment Scale (SCS). We present the different results and highlight the instances in which the methods complement one another so as to obtain a stronger result than would be obtained using only 1 method. Finally, we discuss the implications of the results for the dimensionality of the SCS and provide recommendations for both the further development of the SCS and the future use of PCA and MSA in personality research.     

Parenting, coparenting, and effortful control in preschoolers

This study investigated the relations among parenting, coparenting, and effortful control in preschoolers. The sample included 89 families with 2 parents and their firstborn 36-month-old children. Information was obtained by means of observation and parent-report questionnaires. In general, maternal parenting, paternal parenting, and coparenting were related to effortful control. Effortful control was more strongly predicted from parenting and coparenting when the same measurement method (observation or parent reports) was used. For both observation and parent reports, coparenting contributed to effortful control over and above maternal and paternal parenting. The results indicate the importance of adding indicators of triadic family processes to the study of parenting and young children's effortful control.     

Black Box Arguments

“Black box argument” is a metaphor for modular components of argumentative discussion that are, within a particular discussion, not open to expansion. In public policy debate such as the controversy over abstinence-only sex education, scientific conclusions enter the discourse as black boxes consisting of a result returned from an external and largely impenetrable process. In one way of looking at black box arguments, there is nothing fundamentally new for the argumentation theorist: A black box argument is very like any other appeal to authority, and what might be said about any particular form of black box will turn out to be a particularized version of what might be said about evaluating arguments based on authority. But in another way of looking at black box arguments, they are a constantly evolving technology for coming to conclusions and making these conclusions broadly acceptable. Black boxes are to argumentation what material inventions are to engineering and related sciences. They are anchored in and constrained by fundamental natural processes, but they are also new things that require theoretical explication and practical assessment.     

The effects of weather on daily mood: a multilevel approach

The present study examines the effects of six weather parameters (temperature, wind power, sunlight, precipitation, air pressure, and photoperiod) on mood (positive affect, negative affect, and tiredness). Data were gathered from an online diary study (N = 1,233), linked to weather station data, and analyzed by means of multilevel analysis. Multivariate and univariate analyses enabled distinction between unique and shared effects. The results revealed main effects of temperature, wind power, and sunlight on negative affect. Sunlight had a main effect on tiredness and mediated the effects of precipitation and air pressure on tiredness. In terms of explained variance, however, the average effect of weather on mood was only small, though significant random variation was found across individuals, especially regarding the effect of photoperiod. However, these individual differences in weather sensitivity could not be explained by the Five Factor Model personality traits, gender, or age.     

The Racial Digital Divide: Motivational,Affective, and Cognitive Correlates of Internet Use1

The indisputable existence of a racial digital divide calls into question the democratizing potential of the Internet. Beyond issues of access to the technology are psychological factors that may influence Internet use. A survey of 787 college undergraduates—630 European Americans and 157 African Americans—who have similar access to the Internet was used to examine motivational, affective, and cognitive factors that may influence Internet use and contribute to the racial digital divide. Racial differences in Internet use were obtained, but were limited to e‐mail use. A model of Internet use is offered that considers motivational, affective, and cognitive antecedents and consequences of use.
