The pervasiveness, connectedness, and intrusiveness of social network site use among young adolescents

Young adolescents are quickly becoming avid users of social networking sites (SNSs); however, little is known regarding how they use these sites. The goal of the present study was to examine the extent to which young adolescents use SNSs, with whom they connect via these sites, and whether SNS use disrupts daily functioning. Among 268 middle-school students surveyed, 63% reported having their own profile page on an SNS. On average, adolescents reported having 196 SNS contacts (friends), most of whom were known peers. Young adolescents with an SNS spent most of their time viewing and responding to comments written on their profile page. Among the SNS users, 39% reported getting behind on schoolwork and 37% reported losing sleep at least once because they were visiting an SNS. As SNS use becomes embedded in young teens' daily lives, it is important to better understand how such use affects their daily adaptive functioning.     

Contribution of the dorsal subiculum to memory for temporal order and novelty detection using objects,odors, or spatial locations in the rat

The contribution of the dorsal subiculum (DS) to memory for temporal order and novelty detection was assessed using a spontaneous exploration paradigm with objects (visual/tactile stimuli), odors, or spatial locations (Hunsaker, Fieldsted, Rosenberg, & Kesner, 2008). Rats with selective excitotoxic lesions of the DS were compared to sham-operated rats (SHAM) in the two exploration tests. In temporal order tests, two previously explored stimuli were presented and normal rats typically show a preference for exploring the stimulus that was first explored compared to the other stimulus. In novelty detection tests, a familiar and a new stimulus were presented and normal rats typically have a preference for exploring new stimuli. In temporal order tests, results indicated that Group SHAM explored significantly more the first than the last stimulus they met when the stimuli were odors or objects. In addition, SHAM rats predictably displayed a significant preference for the new stimulus in the novelty detection tests with objects, odors, and spatial locations. Group DS did not differ from controls on the temporal order and the novelty detection tests with objects or odors. However, on the novelty detection test with spatial locations, Group DS differed from Group SHAM. These results suggest that the DS is necessary for the memory of spatial locations but not of objects and odors.     

How verbs can activate things: cross-language activation across word classes

The present study explored whether language-nonselective access in bilinguals occurs across word classes in a sentence context. Dutch–English bilinguals were auditorily presented with English (L2) sentences while looking at a visual world. The sentences contained interlingual homophones from distinct lexical categories (e.g., the English verb spoke, which overlaps phonologically with the Dutch noun for ghost, spook). Eye movement recordings showed that depictions of referents of the Dutch (L1) nouns attracted more visual attention than unrelated distractor pictures in sentences containing homophones. This finding shows that native language objects are activated during second language verb processing despite the structural information provided by the sentence context.     

Gender Differences in the Relations among Patriarchal Beliefs,Parenting, and Teen Relationship Violence in Mexican Adolescents

Teen relationship violence is a global phenomenon associated with adverse outcomes. As in other countries, teen relationship violence is of concern in Mexico. However, few studies have examined the risk and protective factors of teen relationship violence among Mexican adolescents. This study examined whether patriarchal beliefs and exposure to authoritarian parenting among Mexican adolescents are associated with perpetration and victimization of physical and verbal-emotional teen relationship violence. Two hundred and four students (15–18 years old) from Monterrey, Mexico, completed questionnaires. Hierarchical regression analyses controlling for age revealed that among girls, authoritarian parenting was associated with physical and verbal-emotional victimization and verbal-emotional violence perpetration. Among boys, higher endorsement of patriarchal beliefs was associated with lower reports of physical perpetration and physical victimization.     

Animacy increases second target reporting in a rapid serial visual presentation task

Attentional blink occurs when two target items, T1 and T2, are presented within brief moments of each other in a series of rapidly presented items and participants fail to report T2. The purpose of the present study was to examine the effect of characteristics of T2 on T2 reporting. Participants (N = 67) completed 4 blocks of 40 trials. Each trial consisted of 15 images, two of which were designated as T1 and T2. T2 was manipulated in three ways: animacy (animate or inanimate), threat (threatening or nonthreatening), and lag (200 ms or 400 ms after T1). The results indicated that more T2s were reported at the longer lag and that animate objects were reported more often than inanimate objects at both lags. Threat did not have a significant effect on T2 reporting although it interacted with lag: threatening objects were reported more frequently than nonthreatening objects at lag 2 but this trend reversed at lag 4. The results were consistent with the animate monitoring hypothesis, which claims that animate objects, because of their importance in ancestral environments, attract attention more easily than inanimate objects. Animate objects appear to capture attention more easily than inanimate objects as second targets in a rapid serial visual presentation task. This result is similar to animacy advantages reported with other attention tasks and with memory tasks.     

Prediction and Cross-Situational Consistency of Daily Behavior across Cultures: Testing Trait and Cultural Psychology Perspectives

Trait and cultural psychology perspectives on the cross-situational consistency of behavior, and the predictive validity of traits, were tested in a daily process study in the United States (N = 68), an individualistic culture, and the Philippines (N = 80), a collectivistic culture. Participants completed the Revised NEO Personality Inventory (Costa & McCrae, 1992) and a measure of self-monitoring, then reported their daily behaviors and associated situational contexts for approximately 30 days. Consistent with trait perspectives, the Big Five traits predicted daily behaviors in both cultures, and relative (interindividual) consistency was observed across many, although not all, situational contexts. The frequency of various Big Five behaviors varied across relevant situational contexts in both cultures and, consistent with cultural psychology perspectives, there was a tendency for Filipinos to exhibit greater situational variability than Americans. Self-monitoring showed some ability to account for individual differences in situational variability in the American sample, but not the Filipino sample.     

Efficacy of an adaptation of the Best Possible Self intervention implemented through positive technology: a randomized control trial

Best possible Self (BPS) is a positive psychological intervention based on positive future thinking. It has been shown to be effective in improving well-being and depressive symptoms over short periods of time. Positive technology is a scientific approach designed to increase well-being through Information and Communication Technologies. To assess the efficacy of the BPS implemented through a positive technology application in improving optimistic thinking, affect and depressive symptoms, during a one-month period, with two follow-ups one and three months later. Randomized, single-blind control trial. Central randomization was performed by an independent researcher using computer software to generate lists allocating participants to treatments. Recruitment was carried out through advertisements at two universities. Randomized participants were 78 young adults who were assigned to the e-BPS condition (n = 38) or to a control group (n = 40). Participants were asked to visualize their BPS each day using a Positive Technology Application. The Control condition consisted of thinking and writing about daily activities, also through technologies. Affect, future expectations, and depressive symptoms were measured in different time frames. 78 participants were analyzed using intention-to-treat analyses. Results showed that BPS was effective in improving future expectations measures and reducing depressive symptoms until the post-training. However, these effects were not maintained in the three-month follow-up period. This study indicates that BPS can be effectively adapted for implementation through positive technologies. Factors such as the variety of exercises and the instructions can play a role in maintaining the changes in the long term. Trial registration clinicaltrails.gov Identifier: NCT02321605.
