How Users Take Advantage of Different Forms of Interactivity on Online News Sites: Clicking,E‐Mailing,and Commenting

This study examines the uptake of multiple interactive features on news sites. It looks at the thematic composition of the most clicked, most e‐mailed, and most commented stories during periods of heightened and routine political activity. Results show that (a) during the former period, the most commented stories were more likely to be focused on political, economic, and international topics (or “public affairs” news) than the most clicked and most e‐mailed articles. (b) The 3 types of interactivity exhibited a greater presence of public affairs content during the period of heightened political activity than during its routine counterpart. (c) As the period of heightened political activity unfolded, consumers' propensity to click on, e‐mail, and comment about public affairs stories increased.     

Where is the Faith? Using a CBPR Approach to Propose Adaptations to an Evidence-Based HIV Prevention Intervention for Adolescents in African American Faith Settings

African American adolescents are at increased risk for HIV/AIDS. Using a community-based participatory research approach, we engaged three black churches in adapting an evidence-based HIV prevention intervention, Focus on Youth (FOY)+ImPACT, for faith settings. To identify potential adaptations to increase FOY’s relevance, utility, and efficacy for faith settings, we conducted eight focus groups pre- and post-intervention. Recommendations for maintaining FOY’s core elements and enhancing its cultural authenticity include the following: incorporating faith tools, building pastor capacity, strengthening parent–child communication skills, and expanding social support for parents and youth. Engaging faith communities in adapting and implementing evidence-based HIV prevention programs could reduce HIV/AIDS disparities.     

Intelligence as the efficiency of cue-driven retrieval from secondary memory

Complex-span (working-memory-capacity) tasks are among the most successful predictors of intelligence. One important contributor to this relationship is the ability to efficiently employ cues for the retrieval from secondary memory. Presumably, intelligent individuals can considerably restrict their memory search sets by using such cues and can thereby improve recall performance. We here test this assumption by experimentally manipulating the validity of retrieval cues. When memoranda are drawn from the same semantic category on two successive trials of a verbal complex-span task, the category is a very strong retrieval cue on its first occurrence (strong-cue trial) but loses some of its validity on its second occurrence (weak-cue trial). If intelligent individuals make better use of semantic categories as retrieval cues, their recall accuracy suffers more from this loss of cue validity. Accordingly, our results show that less variance in intelligence is explained by recall accuracy on weak-cue compared with strong-cue trials.     

Perceived Pros and Cons of Condom Use as Predictors of its Consistent Use with a Heterosexual Romantic Partner Among Young Adults

The present research examines the pros and cons of condom use as predictors of consistent condom use with a heterosexual romantic partner. Data from 619 undergraduate students (35.1 % males; mean of age?=?20.31) were collected using a voluntary and anonymous self-report survey. The pros and cons predicted consistent condom use during the last month among females, whereas only the pros were predictive of consistent condom use in men. Similarly, only the feelings of safety predicted consistent condom use among men. However, the reduction of pleasure for women, the side-effects of other contraceptive methods, the difficulty in asking for condom use when they were also using the pill and the fact that condom use interrupts and cools off foreplay were also predictors among women. Besides the superiority of the pros over the cons, in general, the present research identifies a number of important pros and cons that should be used to encourage condom use.     

Contextual Pavlovian conditioning in the crab Chasmagnathus

In contextual conditioning, a complex pattern of information is processed to associate the characteristics of a particular place with incentive or aversive reinforcements. This type of learning has been widely studied in mammals, but studies of other taxa are scarce. The context-signal memory (CSM) paradigm of the crab Chasmagnathus has been extensively used as a model of learning and memory. Although initially interpreted as habituation, some characteristics of contextual conditioning have been described. However, no anticipatory response has been detected for animals exposed to the training context. Thus, CSM could be interpreted either as an associative habituation or as contextual conditioning that occurs without a context-evoked anticipatory response. Here, we describe a training protocol developed for contextual Pavlovian conditioning (CPC). For each training trial, the context (conditioned stimulus, CS) was discretely presented and finished together with the unconditioned stimulus (US). In agreement with the CSM paradigm, a robust freezing response was acquired during the 15 training trials, and clear retention was found when tested with the US presentation after short (2 and 4 h) and long (1–4 days) delays. This CPC memory showed forward but not simultaneous presentation conditioning and was context specific and protein synthesis dependent. Additionally, a weak CPC memory was enhanced during consolidation. One day after training, CPC was extinguished by repeated CS presentation, while one presentation induced a memory labilisation–reconsolidation process. Finally, we found an anticipatory conditioned response (CR) during the CS presentation for both short-term (4 h) and long-term memory (24 h). These findings support the conditioning nature of the new paradigm.     

Performance on a Following Tracking Task (Modified Sam Two-Hand Coordination Test) as a Function of Radius of Control Cranks

The influence of two deindividuating variables, altered responsibility and coaction in groups, on one's tendency to deliver noxious or helpful stimulation impulsively and in a cyclical pattern to a target person was investigated in a laboratory experiment with use of 96 male and female junior college students. Analysis of variance revealed that, as hypothesized, Ss who coacted in groups of three and who had the responsibility for their behavior removed delivered noxious (but not helpful) stimuli more impulsively than Ss who worked alone and were made to feel responsible (p < .01). Ss responded in a more cyclical pattern when delivering aversive tones than when delivering facilitating tones (p < .005). A marginally significant finding was that Ss in groups responded in a more cyclical pattern than Ss alone only when the response was seen as aversive. It was concluded that the probability of impulsive and cyclical aggression may be increased by altered responsibility and coaction.     

ideology and the stagnation of aoda treatment modalities in america

The disease model of alcoholism was adopted by the American Medical Assoication in 1956, and the intervening 47 years have seen the development of increasingly varied and sophisticated types of evidence for the biological sources of addiction to Alcohol and other drugs of abuse (AODA) . However, a synthesis of 12-step treatment with a confrontational and moralistic version of cognitive psychology remains the modal approach to AODA treatment, despite its inability to even engage many addicts. Simultaneously, the growing evidence for therapies that teach self-regulation of biopsychological processes, which treat clients supportively while encouraging their recognition of the problems and building their desire to change, has been largely ignored by practitioners. The epitome of this self-regulation approach, neurofeedback therapy, has been all but ignored despite reports of high success rates. This paper examines the confluence historical economic and ideological factors that maintain this divergence between knowledge and practice from the perspective of Gusfield's notion of moral passage based on deviant labels.     

Psychometric analysis of the AF5 multidimensional scale of self-concept in a sample of adolescents and adults in Catalonia

The aim of this study is to carry out a psychometric study of the AF5 scale in a sample of 4.825 Catalan subjects from 11 to 63 years-old. They are students from secondary compulsory education (ESO), from high school, middle-level vocational training (CFGM) and from the university. Using a principal component analysis (PCA) the theoretical validity of the components is established and the reliability of the instrument is also analyzed. Differential analyses are performed by gender and normative group using a 2 x 6 factorial design. The normative group variable includes the different levels classified into 6 sub-groups: university, post-compulsory secondary education (high school and CFGM), 4th of ESO, 3rd of ESO, 2nd of ESO and 1st of ESO. The results indicate that the reliability of the Catalan version of the scale is similar to the original scale. The factorial structure also fits with the original model established beforehand. Significant differences by normative group in the four components of self-concept explored (social, family, academic/occupational and physical) are observed. By gender, significant differences appear in the component of physical self-concept, academic and social but not in the family component.     

Lazos que Atan: The Influence of Normative Gender Beliefs on Sexual Risk Behaviors of Latino Men and Women

Not all Latino men and women conform to proscribed gender roles. Nonetheless, their sexual risk taking may well be influenced by traditional beliefs concerning these roles. We explored the relationship between gender beliefs that are normative in Latino culture, and the sexual risk behaviors of 152 Latino men and women who participated in a behavioral rapid needs assessment survey in Houston, TX. Path—analytic results indicate that normative gender beliefs are influenced by respondents' sex and their levels of acculturation and that these 2 variables influence sexual risk behaviors, including unprotected sex and multi partnerism. Our results suggest that beliefs about gender influence sexual behavior and, therefore, are an important factor that should be considered in understanding sexual risk taking among Latinos.     

Extinction memory in the crab Chasmagnathus: recovery protocols and effects of multi-trial extinction training

A decline in the frequency or intensity of a conditioned behavior following the withdrawal of the reinforcement is called experimental extinction. However, the experimental manipulation necessary to trigger memory reconsolidation or extinction is to expose the animal to the conditioned stimulus in the absence of reinforcement. Recovery protocols were used to reveal which of these two processes was developed. By using the crab contextual memory model (a visual danger stimulus associated with the training context), we investigated the dynamics of extinction memory in Chasmagnathus. Here, we reveal the presence of three recovery protocols that restore the original memory: the old memory comes back 4 days after the extinction training, or when a weak training is administered later, or once the VDS is presented in a novel context 24 h after the extinction session. Another objective was to evaluate whether the administration of multi-trial extinction training could trigger an extinction memory in Chasmagnathus. The results evince that the extinction memory appears only when the total re-exposure time is around 90 min independently of the number of trials employed to accumulate it. Thus, it is feasible that the mechanisms described for the case of the extinction memory acquired through a single training trial are valid for multi-trial extinction protocols. Finally, these results are in agreement with those reports obtained with models phylogenetically far apart from the crab. Behind this attempt is the idea that in the domain of studies on memory, some principles of behavior organization and basic mechanisms have universal validity.
