Predicting Treatment Response in Older Adults with Insomnia

This study examined potential predictors of treatment outcome in late-life insomnia. Fifty-four older adults with chronic insomnia were treated with cognitive–behavior therapy (CBT), pharmacotherapy (PCT), or combined CBT plus PCT. Pretreatment characteristics such as demographic, clinical, psychometric, and sleep variables were examined as correlates or potential predictors of treatment response. Treatment response was defined by posttreatment sleep efficiency as measured subjectively by daily sleep diary and objectively by polysomnography. The results indicate that age, insomnia duration, medical illness, and previous use of sleep medications can moderate subjective or objective treatment outcome or both of these in late-life insomnia. However, there are no reliable predictors of outcome across all treatment and assessment modalities. The implications of these findings for the treatment of insomnia in older adults seen in primary care settings are discussed.     

Computer simulations as experiments

Whereas computer simulations involve no direct physical interaction between the machine they are run on and the physical systems they are used to investigate, they are often used as experiments and yield data about these systems. It is commonly argued that they do so because they are implemented on physical machines. We claim that physicality is not necessary for their representational and predictive capacities and that the explanation of why computer simulations generate desired information about their target system is only to be found in the detailed analysis of their semantic levels. We provide such an analysis and we determine the actual consequences of physical implementation for simulations. A. Barberousse, S. Franceschelli and C. Imbert have contributed equally to this work.     

Sexting,Mobile Porn Use,and Peer Group Dynamics: Boys' and Girls' Self-Perceived Popularity,Need for Popularity,and Perceived Peer Pressure

There is considerable concern about adolescents producing, consuming, and distributing sexual materials via mobile phone communication. The purpose of this study was to examine key aspects of peer influence and the peer context in relation to two such practices: sexting and mobile porn use. The results of a high-school survey study (N = 1,943) revealed that 6% of Flemish teens (11–20 years of age) have sent a sext, while 9% use mobile porn. Teens who were more popular with the other sex and with a greater need for popularity were more likely to report both behaviors. Boys' mobile porn use was also predicted by perceived peer pressure. Same-sex popularity was unrelated to boys' sexting behavior and mobile porn use; for girls, a negative relationship was found.     

On The Nature of Experiencing Self‐Agency: The Role of Goals and Primes in Inferring Oneself as the Cause of Behavior

People often find themselves in situations where the cause of events may be ambiguous. Surprisingly though, the experience of self‐agency, i.e., perceiving oneself as the causal agent of behavioral outcomes, appears quite natural to most people. How then do these experiences arise? We discuss common models proposing that self‐agency experiences result from the comparison between actual action‐outcomes and the outcomes one explicitly set as a goal. However, recent developments in psychology and neuroscience suggest that our behaviors and the outcomes they produce can be primed and implicitly guided by environmental cues and yet are accompanied by experiences of self‐agency. Hence, we also review research revealing how self‐agency experiences may arise over behavioral outcomes that are implicitly primed before they occur and how such implicitly cued agency experiences may differ from agency experiences that are the result of explicitly set goals. Directions for future research are briefly addressed.     

The presence of the past: Identity continuity and group dynamics

Social psychologists are increasingly interested in the temporal dimensions of social life and in identity continuity in particular. Focusing on ethnicity and national identity we discuss the implications of perceived group continuity and collective self-continuity, and their interplay, for group dynamics. Using the social identity perspective and theories of identity motivation, we show, first, that the need for collective self-continuity forms a unique motivational basis for group identification. Second, we demonstrate that people are more likely to derive a sense of collective self-continuity from groups that are seen as relatively stable and immutable over time (i.e., essentialist in-groups). Third, we find that existential threats to group identity strengthen a sense of collective self-continuity, which, in turn, increases in-group defence mechanisms in the form of negative attitudes towards immigrant out-groups and towards social developments that potentially undermine in-group continuity. Fourth, we discuss empirical findings that indicate that group-based nostalgia for the nation is an identity management strategy in response to in-group continuity threats and that nostalgia leads to immigrant out-group exclusion.     

Response Inhibition and Measures of Psychopathology: A Dimensional Analysis

On the basis of Quay's (1988a, 1988b, 1993, 1997) model in which the Behavioral Inhibition System (BIS) and the Behavioral Activation System (BAS) are linked to various forms of child psychopathology, predictions were made regarding the relation between inhibitory control and two dimensions of psychopathology: externalizing and internalizing behavior. Inhibitory control was measured using two versions of Logan and Cowan's stop signal paradigm (1984; Logan, Cowan, & Davis, 1984; Osman, Kornblum, & Meyer, 1986, 1990). The primary outcome measure for the stop tasks was stop signal reaction time (SSRT) which measures the latency of the inhibition process. A positive relationship was predicted for externalizing behavior, whereas a negative relationship was predicted for internalizing behavior. A total of 42 non-clinical elementary school children, in the age range of 6 to 12 years, participated in the study. Externalizing behavior was positively related to response inhibition. Symptoms of ADHD seem to be better at predicting inhibitory functioning than symptoms of aggressive behavior disorders. Some support was found for a negative relation between internalizing behavior and inhibitory control. These findings support Quay's model and the discriminant validity of inhibitory control with regard to externalizing and internalizing behavior.     

Response Inhibition in Children With DSM-IV Subtypes of AD/HD and Related Disruptive Disorders: The Role of Reward

The current study had four aims: (a) to replicate previous findings of slow response inhibition in Attention Deficit/Hyperactivity Disorder (AD/HD), (b) to explore whether poor response inhibition in children with AD/HD is a core problem or rather a result of an underlying problem related to reward, (c) to investigate the specificity of poor response inhibition and the role of reward in relation to AD/HD, and (d) to study whether findings would be different for three subtypes of AD/HD. In order to address these issues, a stop paradigm was administered under a reward condition and under a nonreward condition to an AD/HD group (n = 24), an Oppositional Defiant Disorder (ODD)/Conduct Disorder (CD) group (n = 21), a comorbid AD/HD+ODD/ CD group (n = 27), and a normal control (NC) group (n = 41). Firstly, contrary to prediction, none of the Disruptive Behavior Disorder (DBD) groups differed from the NC group with respect to the speed of the inhibition process. Secondly, it was shown that children with AD/HD and children with comorbid AD/HD+ODD/CD, but not children with ODD/CD alone, slowed down more dramatically in the reward condition than normal controls. This finding was interpreted as a strategy to increase the chance of being rewarded in children with AD/HD and children with comorbid AD/HD+ODD/CD, but not in children with pure ODD/CD. Finally, analysis of AD/HD subtypes did not change the main findings of this study.     

Interactions between goal-directed eye and arm movements: arguments for an interdependent motor control

The accuracy of movements of the arm directed toward a point in space was investigated in healthy human subjects. To study the influence of the eye movement itself, on the guidance of the arm in the absence of any visual context, subjects performed the goal-directed arm movements without visual feedback about the arm displacement and the target position. The subjects were asked either to keep their eyes centered or oriented toward a previously flashed target. The analysis of the distribution of the errors in arm final position in the two conditions suggests that the eye movement influences the final position adopted by the arm. It is postulated that an interaction exists between the eye and arm systems during the motor program elaboration phase.     

An exploration of spiritual superiority: The paradox of self‐enhancement

Spiritual training is assumed to reduce self‐enhancement, but may have the paradoxical effect of boosting superiority feelings. It can thus operate like other self‐enhancement tools and contribute to a contingent self‐worth that depends on one's spiritual accomplishments. In three studies (N = 533, N = 2,223, N = 965), a brief measure of spiritual superiority showed good internal consistency and discriminant validity. As predicted, it was distinctly related to spiritual contingency of self‐worth, illustrating that the self‐enhancement function of spirituality is similar to other contingency domains. It was correlated with self‐esteem and, more strongly, with communal narcissism, corroborating the notion of spiritual narcissism. Spiritual Superiority scores were consistently higher among energetically trained participants than mindfulness trainees and were associated with supernatural overconfidence and self‐ascribed spiritual guidance. Our results illustrate that the self‐enhancement motive is powerful and deeply ingrained so that it can hijack methods intended to transcend the ego and, instead, adopt them to its own service.
