Sustained Attention and Executive Functioning Performance in Attention-Deficit/Hyperactivity Disorder

The aim of this study was to further refine the cognitive phenotype of attention-deficit/hyperactivity disorder (ADHD), with respect to the ability to sustain attention and executive functioning. Participants were 34 boys with ADHD (combined type) and 28 normal controls. The groups were closely matched for age and IQ. All participants were 12 years of age. Both groups performed a computerized sustained attention task and a response interference task. Measures related to speed, accuracy, and time on task were collected. We found that children with ADHD performed slower, less accurately, more impulsively, and with less stability than controls. Both groups produced more errors with increasing time on task, reflecting reduced vigilance. Importantly, no interaction with time on task was found. The overall pattern of results suggests that measures related to accuracy are more informative than measures related to speed of responding in refining the cognitive phenotype of ADHD.     

Extending the Rorschach Trauma Content Index and Aggression Indexes to Dream Narratives of Children Exposed to Enduring Violence: An Exploratory Study

The relationship between a measure of interpersonal stress and report of physical symptoms was investigated. The data were obtained on 85 undergraduate students using a structured diary for a period of one week. A positive relationship was found between the diary measure of interpersonal stress and an overall tendency to report physical complaints. Positive relationships were also found between the measure of interpersonal stress and report of specific symptoms, such as dizziness and back problems. Interpersonal stress appeared higher on symptom days than non-symptom days but little evidence was found for higher stress on days immediately preceding symptoms.     

Distinct pathways to persuasion: The role of affect in message‐framing effects

Health‐promoting messages can be framed in terms of the gains that are associated with healthy behaviour (gain frame) or the losses that are associated with unhealthy behaviour (loss frame). In the present research, we examined the role of positive and negative affect in the persuasive effects of gain‐ and loss‐framed health‐promoting information. Experiment 1 (N = 98) showed that gain‐framed information resulted in higher levels of information acceptance than loss‐framed information and that this effect was mediated by positive affect. The results of Experiment 2 (N = 129) showed that gain‐framed information resulted in higher levels of information acceptance and attitude, an effect that was again mediated by positive affect. In addition, loss‐framed information resulted in more negative affect than gain‐framed information and negative affect increased participants' intention to engage in the healthy behaviour. These results suggest that affect may be of great importance in the persuasion process and may be particularly helpful to explain the underlying mechanisms of message framing effects. The findings also suggest that gain‐ and loss‐framed messages offer distinct pathways to persuasion. Copyright © 2009 John Wiley & Sons, Ltd.     

The effectiveness of family-based cognitive-behavior grief therapy to prevent complicated grief in relatives of suicide victims: the mediating role of suicide ideation

Grief interventions are more effective for high risk individuals. The presence of suicide ideation following suicide bereavement was examined to determine whether it indicates a high risk status. Using data from a randomized controlled trial (n = 122) on the effectiveness of cognitive-behavior therapy, the effect of suicide ideation on the effectiveness of grief therapy on the bereavement outcome at 13 months post loss was examined. Results show that suicide ideators more often have a history of mental disorder and suicidal behavior than non-ideators, and suicide ideation indicates a high risk for adverse bereavement outcome. Grief therapy likely reduces the risk of maladaptive grief reactions among suicide ideators. Therefore, suicide ideators may benefit from grief therapy following a loss through suicide.     

Brand placement disclosure effects on persuasion: The moderating role of consumer self‐control

The inclusion of branded products in media entertainment has become a popular marketing strategy, because viewers are less likely to recognize the persuasive intent of sponsored content as compared with traditional advertising. To guarantee fair communication and protect consumers against unobtrusive persuasion attempts, European media policy has obligated broadcasters to disclose the presence of brand placement in their television shows. Recent studies demonstrate that disclosures raise viewers' persuasion knowledge; however, the circumstances under which brand placement disclosures may affect brand evaluations and resistance to the persuasive impact of brand placement are still unclear. In two experiments, we uncovered self‐control depletion as an important moderator of disclosure effects on brand evaluations and resistance to brand placement influence. Whereas disclosures increase resistance and decrease persuasion for viewers not depleted of their self‐control, disclosures do not affect resistance and even result in more favorable brand evaluations when viewers' self‐control is depleted by a previous self‐control task. Because a state of self‐control depletion can be perceived as the “couch‐potato” mindset in which people expose themselves to entertaining television content, our findings imply that instead of protecting consumers from hidden persuasion, disclosures may unintentionally increase the persuasive effects of brand placement. We discuss several possible mechanisms that could explain our findings. Copyright © 2016 John Wiley & Sons, Ltd.     

Relative Difficulty of Understanding Foreign Accents as a Marker of Proficiency

Foreign‐accented speech is generally harder to understand than native‐accented speech. This difficulty is reduced for non‐native listeners who share their first language with the non‐native speaker. It is currently unclear, however, how non‐native listeners deal with foreign‐accented speech produced by speakers of a different language. We show that the process of (second) language acquisition is associated with an increase in the relative difficulty of processing foreign‐accented speech. Therefore, experiencing greater relative difficulty with foreign‐accented speech compared with native speech is a marker of language proficiency. These results contribute to our understanding of how phonological categories are acquired during second language learning.     

A clusterwise simultaneous component method for capturing within‐cluster differences in component variances and correlations

This paper presents a clusterwise simultaneous component analysis for tracing structural differences and similarities between data of different groups of subjects. This model partitions the groups into a number of clusters according to the covariance structure of the data of each group and performs a simultaneous component analysis with invariant pattern restrictions (SCA‐P) for each cluster. These restrictions imply that the model allows for between‐group differences in the variances and the correlations of the cluster‐specific components. As such, clusterwise SCA‐P is more flexible than the earlier proposed clusterwise SCA‐ECP model, which imposed equal average cross‐products constraints on the component scores of the groups that belong to the same cluster. Using clusterwise SCA‐P, a finer‐grained, yet parsimonious picture of the group differences and similarities can be obtained. An algorithm for fitting clusterwise SCA‐P solutions is presented and its performance is evaluated by means of a simulation study. The value of the model for empirical research is illustrated with data from psychiatric diagnosis research.     

Task‐ and self‐related pathways to deep learning: The mediating role of achievement goals,classroom attentiveness,and group participation

Background The expectancy‐value and achievement goal theories are arguably the two most dominant theories of achievement motivation in the contemporary literature. However, very few studies have examined how the constructs derived from both theories are related to deep learning. Moreover, although there is evidence demonstrating the links between achievement goals and deep learning, little research has examined the mediating processes involved. Aims The aims of this research were to: (a) investigate the role of task‐ and self‐related beliefs (task value and self‐efficacy) as well as achievement goals in predicting deep learning in mathematics and (b) examine how classroom attentiveness and group participation mediated the relations between achievement goals and deep learning. Sample The sample comprised 1,476 Grade‐9 students from 39 schools in Singapore. Methods Students' self‐efficacy, task value, achievement goals, classroom attentiveness, group participation, and deep learning in mathematics were assessed by a self‐reported questionnaire administered on‐line. Structural equation modelling was performed to test the hypothesized model linking these variables. Results and conclusions Task value was predictive of task‐related achievement goals whereas self‐efficacy was predictive of task‐approach, performance‐approach, and performance‐avoidance goals. Achievement goals were found to fully mediate the relations between task value and self‐efficacy on the one hand, and classroom attentiveness, group participation, and deep learning on the other. Classroom attentiveness and group participation partially mediated the relations between achievement goal adoption and deep learning. The findings suggest that (a) task‐ and self‐related pathways are two possible routes through which students could be motivated to learn and (b) like task‐approach goals, performance‐approach goals could lead to adaptive processes and outcomes.     

Extending the Rorschach trauma content index and aggression indexes to dream narratives of children exposed to enduring violence: an exploratory study

In this study, we compared dream narratives of children and adolescents living under conditions of enduring interpersonal violence (n = 220) versus those living in peaceful surroundings (n = 99) on content variables that have been associated with traumatic experiences in Rorschach (Exner, 1995) imagery. As predicted, children and adolescents living in circumstances of enduring violence reported a higher proportion of content scorable by Armstrong and Loewenstein's (1990) Trauma Content Index and a much higher proportion of aggressive objects in their dreams (AgC; Gacono & Meloy, 1994). In support of discriminant validity, no consistent group differences were observed for the relative frequencies of Animal (A), Clothing (Cg), or Cooperative movement (COP) content. The modest association between manifest dream content and psychological symptom scales suggests that the former may alternatively reflect adaptive or psychopathological processes. Our findings suggest that content analysis of dreams may be a valuable adjunct in tapping the psychological state of children traumatized by violence.     

Justice and the human alarm system: The impact of exclamation points and flashing lights on the justice judgment process

Extending theory within the justice domain and work on the human alarm system, the current paper argues that the process by which justice judgments are formed may be influenced reliably by the activation of psychological systems that people use to detect and handle alarming situations. Building on this analysis, it is further proposed that if this line of reasoning is true then presenting alarm-related stimuli, such as exclamation points and flashing lights, to people should lead to more extreme judgments about subsequent justice-related events than not presenting these alarming stimuli. Findings collected using different experimental paradigms provide evidence supporting these predictions both inside and outside the psychology lab. Implications for the social psychology of justice and the human alarm system literature are discussed.
