Social Consequences of the Internet for Adolescents: A Decade of Research

ABSTRACT— Adolescents are currently the defining users of the Internet. They spend more time online than adults do, and they use the Internet for social interaction more often than adults do. This article discusses the state of the literature on the consequences of online communication technologies (e.g., instant messaging) for adolescents' social connectedness and well-being. Whereas several studies in the 1990s suggested that Internet use is detrimental, recent studies tend to report opposite effects. We first explain why the results of more recent studies diverge from those of earlier studies. Then, we discuss a viable hypothesis to explain the recent findings: the Internet-enhanced self-disclosure hypothesis. Finally, we discuss some contingent factors that may deserve special attention in future research.     

How Emotions Regulate Social Life: The Emotions as Social Information (EASI) Model

ABSTRACT— The idea that emotions regulate social interaction is increasingly popular. But exactly how do emotions do this? To address this question, I draw on research on the interpersonal effects of emotions on behavior in personal relationships, parent–child interactions, conflict, negotiation, and leadership, and propose a new framework that can account for existing findings and guide future research: the emotions as social information (EASI) model. I demonstrate that emotional expressions affect observers' behavior by triggering inferential processes and/or affective reactions in them. The predictive strength of these two processes—which may inspire different behaviors—depends on the observer's information processing and on social-relational factors. Examples of moderators that determine the relative predictive strength of inferences and affective reactions include power, need for cognitive closure, time pressure, display rules, and the appropriateness and target of the emotional expression, which are all discussed.     

Dissociating the effects of angular disparity and image similarity in mental rotation and object recognition

Performance is often impaired linearly with increasing angular disparity between two objects in tasks that measure mental rotation or object recognition. But increased angular disparity is often accompanied by changes in the similarity between views of an object, confounding the impact of the two factors in these tasks. We examined separately the effects of angular disparity and image similarity on handedness (to test mental rotation) and identity (to test object recognition) judgments with 3-D novel objects. When similarity was approximately equated, an effect of angular disparity was only found for handedness but not identity judgments. With a fixed angular disparity, performance was better for similar than dissimilar image pairs in both tasks, with a larger effect for identity than handedness judgments. Our results suggest that mental rotation involves mental transformation procedures that depend on angular disparity, but that object recognition is predominately dependent on the similarity of image features.     

Empirical comparison of Markov and quantum models of decision making

There are at least two general theories for building probabilistic-dynamical systems: one is Markov theory and another is quantum theory. These two mathematical frameworks share many fundamental ideas, but they also differ in some key properties. On the one hand, Markov theory obeys the law of total probability, but quantum theory does not; on the other hand, quantum theory obeys the doubly stochastic law, but Markov theory does not. Therefore, the decision about whether to use a Markov or a quantum system depends on which of these laws are empirically obeyed in an application. This article derives two general methods for testing these theories that are parameter free, and presents a new experimental test. The article concludes with a review of experimental findings from cognitive psychology that evaluate these two properties.     

Self-Interest, Symbolic Attitudes, and Support for Public Policy: A Multilevel Analysis

This paper examines the role of self-interest and symbolic attitudes as predictors of support for two domestic policy issues—guaranteed jobs and incomes and national health insurance—in the American National Election Survey (ANES) between 1972 and 2004. As was the case in 1976 when Sears, Lau, Tyler, and Allen (1980 ) first explored this topic, symbolic attitudes continue to be much more important predictors of policy attitudes than various indicators of self-interest over the 30 years we analyze. We explore this finding further to determine whether any individual/internal and external/contextual variables affect the magnitude of self-interest effects on policy support. Five possible internal moderators of self-interest effects are examined: (1) political knowledge, (2) issue publics, (3) political values, (4) social identifications, and (5) emotions, but none are found to boost the magnitude of the self-interest effect. However, we do find some evidence that contextual variables representing the social/information environment moderate the impact of self-interest on public opinion.     

Neuropsychological and Behavioral Effects of Antiepilepsy Drugs

Antiepilepsy drugs work by decreasing neuronal irritability, which may also result in the non-desired side effect of decreased neuropsychological function. In addition to cognitive side effects, antiepilepsy drugs (AEDs) may be associated with behavioral effects which may range from irritability and hyperactivity to positive psychotropic effects on mood. There have been many new medications released since the 1990s, and although they tend to have more favorable side effect profiles compared to their older counterparts, there continues to be a risk of decreased cognitive function with the majority of these agents. The effects of in utero antiepilepsy drug exposure are increasingly being investigated, and differential drug risk is beginning to be described for both anatomic and cognitive outcomes. Patients with epilepsy undergoing neuropsychological evaluations are commonly on AEDs, and it is important for the clinician to recognize the potential contribution of AED therapy to neuropsychological profiles. The present article serves to provide an overview of our current understanding regarding the risks of antiepilepsy drug use for both cognitive and behavioral side effects.     

The Role of Stimulus Specificity on Infidelity Reactions: Seeing is Disturbing

Past research has found that males are more distressed by imagined scenarios of sexual infidelity compared with females, while females are more distressed by imagined scenarios of emotional infidelity. Expanding on the methodology originally employed by Buss et al. (Psychological Science, 3, 251–255, 1992), we examined sex differences in reactions to imagined infidelity by addressing the effects of visual images of potential interlopers. Additionally, this research measured affective responses in a continuous format by examining psychological discomfort. Participants in high-visual imagery and control conditions imagined infidelity (both emotional and sexual) and then reported levels of discomfort. Further, two indices of autonomic nervous system responding were assessed (skin conductance and pulse rate). Ninety-three (53 females, 40 males) college students participated. Visual stimuli produced greater psychological distress than thought-produced stimuli for all participants, especially males. Sex differences in reactions to infidelity consistent with past research were obtained for the categorical and continuous psychological indices. Implications for research in this area are discussed.

The interactive effects of temperament and maternal parenting on toddlers' externalizing behaviours

The present study aimed to determine the potential moderating effects of temperamental traits on the relation between parenting and toddlers' externalizing behaviours. For that purpose, this study examined the interplay between temperament and maternal parenting behaviours in predicting the level as well as the development of toddlers' externalizing behaviours. Participants were 115 boys (wave 1, M=16.9 months; wave 2, M=23.2 months) and their mothers, who were observed in a 13‐min structured play session at home. With regard to the prediction of the level of externalizing behaviours at wave 1, main effects were found for children's temperamental characteristics. In addition, maternal negative control interacted significantly with children's inhibitory control in predicting this level of externalizing behaviours. The findings with regard to the development of externalizing behaviours showed that the effects of maternal negative control and lack of maternal sensitivity were stronger for toddlers with a difficult temperament: maternal negative control and lack of maternal sensitivity were related to an increase in externalizing behaviours for temperamentally difficult children only. These results offer support for the goodness‐of‐fit hypothesis, stressing the idea that the effects of temperament and the social environment depend to a large extent on their interplay.
