Parental Strategies for Knowledge of Adolescents’ Friends: Distinct from Monitoring?

Parental monitoring is defined as a set of behaviors used to gain knowledge about an adolescent’s whereabouts, friends and associates, and activities. However, can knowledge of adolescents’ whereabouts/activities, and friends all be attained through the same strategies? Or do they require their own strategies? This study used qualitative interviews with 173 parents of older adolescents from 100 families. Emergent themes described strategies by which parents gain information about their adolescents’ friends and the substance use of those friends. The strategies included direct interaction with the friend, gaining information from the teen, using second-hand sources, and making assumptions. Some of these strategies were consistent with previous research, while others raise new questions and provide interesting new directions to pursue. Primarily, additional consideration needs to be given to assessments of parental monitoring that include strategies for gaining knowledge of adolescents’ friends and their substance use.     

Sibling jealousy in early childhood: longitudinal links to sibling relationship quality

The current investigation examined the long‐term prediction of sibling jealousy assessed in a laboratory‐based paradigm on sibling relationship quality 2 1/2 years later. This multi‐method longitudinal study included mothers, fathers, and two children from 35 families. Younger siblings were 16 months and older siblings were, on average, 4 years at Time 1. Positive longitudinal associations were found between older siblings' jealousy reactions when interacting with the father at Time 1 and sibling conflict at Time 2. These associations continued to exist even when older siblings' behaviour during the mother sessions was considered. Children's inability to regulate their jealous reactions may be indicative of lower levels of emotion regulation skills, which may, in turn, translate to poorer sibling interactions years later.

Hierarchy and scope of planning in subject–verb agreement production

Two subject–verb agreement error elicitation studies tested the hierarchical feature-passing account of agreement computation in production and three timing-based alternatives: linear distance to the head noun, semantic integration, and a combined effect of both (a scope of planning account). In Experiment 1, participants completed subject noun phrase (NP) stimuli consisting of a head NP followed by two prepositional phrase (PP) modifiers, where the first PP modified the first NP, and the second PP modified one of the two preceding NPs. Semantic integration between the head noun and the local noun within each PP was held constant across structures. The mismatch error pattern showed an effect of linear distance to the head noun and no influence of hierarchical distance. In Experiment 2, participants completed NP PP PP stimuli in which both PPs modified the head noun, and both the order of the two PPs and the local nouns’ degree of semantic integration with the head noun were varied. The pattern of mismatch errors reflected a combination of semantic integration and linear distance to the head noun. These studies indicate that agreement processes are strongly constrained by grammatical-level scope of planning, with local nouns planned closer to the head having a greater chance of interfering with agreement computation.     

Early sexual experiences: the role of Internet access and sexually explicit material.

The current study investigated whether viewing X-rated movies, Internet access in the home, and gender of the participant would differ between age of first initiation for oral sex, age of first initiation for sexual intercourse, and number of sexual partners. An online sample of 437 participants with an average age of 29.46 participated in the study. Each participant completed a survey that assessed early sexual behaviors and Internet and X-rated material exposure. Results discovered males with Internet access during the ages of 12 to 17 reported significantly younger ages for first oral sex compared to males without Internet access. In addition, male and female participants with Internet access, between the ages 12 to 17, reported younger ages for first sexual intercourse compared to participants without Internet access. Study limitations and implications are discussed.     

Towards better computational models of the balance scale task: a reply to Shultz and Takane

In contrast to Shultz and Takane [Shultz, T.R., & Takane, Y. (2007). Rule following and rule use in the balance-scale task. Cognition, in press, doi:10.1016/j.cognition.2006.12.004.] we do not accept that the traditional Rule Assessment Method (RAM) of scoring responses on the balance scale task has advantages over latent class analysis (LCA): RAM is similar to a very restricted form of LCA. The apparent shortcomings of LCA are also less severe than they suggest. Via new simulations we show that LCA detects small classes reliably. We also counter their concerns regarding the torque difference effect and we underline the problems connectionist models have with correctly responding to balance items. Despite these differences in opinion we agree with Shultz and Takane on the possible avenues for future research.     

Coparenting and early conscience development in the family

In the current research, the authors examined children's observed compliance in a family clean-up paradigm and parents' reports of coparenting to predict young children's conscience (e.g., affective discomfort and moral regulation) in a sample of 58 families with two parents and at least two children. The authors found relations between parents' reports of children's conscience development and observer-rated compliance in a family clean-up session, and significant correlations between coparenting and conscience development. There were a greater number of significant results for younger, 2-year-old siblings than for older siblings, which may reflect the importance of the period between 2 and 3 years for the emergence of conscience. Multiple regressions revealed that younger siblings' age, observed compliance/noncompliance, and parents' reports of coparenting were all significant in predicting parents' reports of affective discomfort and moral regulation. Findings underscore the importance of continuing research on whole-family dynamics when studying young children's early conscience and moral regulation.     

Priming meritocracy and the psychological justification of inequality

The belief that status in society is based on merit is a central feature of the American Dream. This belief system justifies status inequalities by locating the cause of status differences in the individual talents and efforts of group members. We hypothesized that activating meritocratic beliefs increases the extent to which individuals psychologically justify status inequalities, even when those inequalities are disadvantageous to the self. Specifically, we hypothesized that priming meritocracy prompts individuals to engage in system-justifying psychological responses when they experience threat either at the personal or group level. Across two studies, priming meritocracy led members of a low status group to justify both personal and group disadvantage by decreasing perceptions of discrimination (Studies 1 and 2) and increasing the extent to which they stereotyped themselves and their group in status-justifying ways (Study 2).     

Visual and haptic feedback contribute to tuning and online control during object manipulation

The authors employed a virtual environment to investigate how humans use haptic and visual feedback in a simple, rhythmic object-manipulation task. The authors hypothesized that feedback would help participants identify the appropriate resonant frequency and perform online control adjustments. The 1st test was whether sensory feedback is needed at all; the 2nd was whether the motor system combines visual and haptic feedback to improve performance. Task performance was quantified in terms of work performed on the virtual inertia, ability to identify the correct rhythm, and variability of movement. Strict feedforward control was found to be ineffective for this task, even when participants had previous knowledge of the rhythm. Participants (N = 11) performed far better when feedback was available (11 times more work, 2.2 times more precise frequency, 30% less variability; p < .05 for all 3 performance measures). Using sensory feedback, participants were able to rapidly identify 4 different spring-inertia systems without foreknowledge of the corresponding resonant frequencies. They performed over 20% more work with 24% less variability when provided with both visual and haptic feedback than they did with either feedback channel alone (p < .05), providing evidence that they integrated online sensory channels. Whereas feedforward control alone led to poor performance, feedback control led to fast tuning or calibration of control according to the resonant frequency of the object, and to better control of the rhythmic movement itself.
