Old and new ways to study characteristics of reading disability: The case of the nonword-reading deficit

Theoretical and computational models of reading have traditionally been informed by specific characteristics of disabled readers. One of the most frequently studied marker effects of developmental dyslexia is the nonword-reading deficit. Disabled readers are generally believed to show a specific problem in reading nonwords. This study presents a survey of frequently cited methods used to examine this effect by controlling general reading ability in various ways. An extensive analysis, however, shows that the majority of these methods (grade equivalents scores, the reading-level match design, and interactions in a chronological-age match design) actually fail to account for confounding variables such as age and general slowing, potentially affecting the conclusions reached. To alleviate this problem, an alternative method is presented: i.e. state trace analysis. Applying this method in a sample of Dutch disabled and typical readers, the results revealed an absence of a nonword-reading deficit in the disabled readers. Furthermore, after controlling for their decoding ability, disabled readers showed inferior word reading performance, which strongly suggests that the fundamental problem of disabled readers does not relate to the reading of nonwords but concerns their (dis)ability to acquire orthographic (word-specific) knowledge. Further, predictions for disabled readers in an inconsistent orthography like English are formulated. Finally, based on a review of neurobiological studies, implications for theories of reading disability are discussed.     

Boys don't cry: Cognitive load and priming increase stereotypic sex differences in emotion memory

The results of three experiments provide evidence that the relative accessibility of stereotypes about sex difference influences people's memory of very recent emotions. Being under high rather than low cognitive load caused females compared with males to recall experiencing more intense emotional reactions to saddening stimuli (Experiments 1 and 2), and relatively less intense reactions to angering stimuli (Experiment 2). Being directly primed with stereotypes about sex differences and being under high cognitive load both caused females to recall more intense reactions to saddening stimuli compared with females who were neither primed with stereotypes nor under cognitive load (Experiment 3). These results imply that the relative accessibility of stereotypes influences memories of emotion in a manner similar to stereotypes' influence on social perception. Implications of these findings for theories of emotion memory and for self-perpetuating stereotypes about emotional sex differences are discussed.     

Why People Gossip: An Empirical Analysis of Social Motives,Antecedents, and Consequences

In 3 studies with student samples, we advance a social‐motivational approach to gossip. We developed the Motives to Gossip Questionnaire to distinguish negative influence, information gathering and validation, social enjoyment, and group protection as motives underlying gossip. Study 1 demonstrated that these motives can be distinguished empirically, and that the informational motive was the most prevalent reason to instigate gossip. Study 2 showed that group protection was especially important when the opportunity to gossip with a group member about another member's norm‐violating behavior was salient. Study 3 showed that when participants imagined someone gossiped to them about another group member's norm violation, and ascribed this to group protection, they rated the gossip as social and did not disapprove of it.     

Determinants of Attitudes Toward Muslim Students Among Flemish Teachers: A Research Note

Muslims are now the second largest religious group in almost all Western countries and a large majority of Muslim citizens are children who attend schools. However teachers’ attitudes regarding the education of Muslim students are largely ignored by educational researchers. In this study, we investigate the determinants of teachers’ attitudes among Flemish (Belgian) teachers (N = 620). Regression analysis has revealed that female teachers, Muslim teachers, younger teachers, and teachers with a four‐year college degree have significantly more positive attitudes. Most interestingly, we found that teachers working in schools that enroll a larger share of Muslim students (greater than 50 percent) have more negative attitudes toward Muslim students than other teachers. The implications of these findings for educational policy are discussed.     

Navigating the Black Hole: Explicating Layers of Job Search Context and Adaptational Responses

Via a qualitative study, we introduce and elucidate 5 layers of context‐related job search demands (omnibus, organizational, social, task, and personal) that are encountered by both employed and unemployed job seekers. We develop a process model to portray the mechanisms (managing mood and motivation, feedback/help seeking, and self‐reflection/learning) through which these context‐related demands are related to several important job search outcomes. We provide new insight into employed job seekers, showing that they report the job search as full of difficulties, obstacles, and challenges, and that some of these demands parallel those that unemployed job seekers face.     

The SIMCLAS Model: Simultaneous Analysis of Coupled Binary Data Matrices with Noise Heterogeneity Between and Within Data Blocks

In many research domains different pieces of information are collected regarding the same set of objects. Each piece of information constitutes a data block, and all these (coupled) blocks have the object mode in common. When analyzing such data, an important aim is to obtain an overall picture of the structure underlying the whole set of coupled data blocks. A further challenge consists of accounting for the differences in information value that exist between and within (i.e., between the objects of a single block) data blocks. To tackle these issues, analysis techniques may be useful in which all available pieces of information are integrated and in which at the same time noise heterogeneity is taken into account. For the case of binary coupled data, however, only methods exist that go for a simultaneous analysis of all data blocks but that do not account for noise heterogeneity. Therefore, in this paper, the SIMCLAS model, being a Hierarchical Classes model for the simultaneous analysis of coupled binary two-way matrices, is presented. In this model, noise heterogeneity between and within the data blocks is accounted for by downweighting entries from noisy blocks/objects within a block. In a simulation study it is shown that (1) the SIMCLAS technique recovers the underlying structure of coupled data to a very large extent, and (2) the SIMCLAS technique outperforms a Hierarchical Classes technique in which all entries contribute equally to the analysis (i.e., noise homogeneity within and between blocks). The latter is also demonstrated in an application of both techniques to empirical data on categorization of semantic concepts.     

Prosocial consequences of imitation

Research has shown that helping behavior can be primed easily. However, helping decreases significantly in the presence of inhibition cues, signaling high costs for the executor. On the other hand, multiple studies demonstrated that helping behavior increases after being mimicked. The present study investigated whether imitation still increases helping when more substantial costs are involved. Helping behavior was operationalized as the willingness to accompany the confederate on a 15-20 minute walk to the train station. Results show that even in the face of these high costs, participants who were mimicked agreed more often to help the confederate than participants who were anti-mimicked. These findings suggest that mimicry not only makes people more helpful when it comes to small favors, but also allows them to ignore the substantial costs possibly involved in helping others.     

Can Reasons be Self-Undermining?

The characterization of objective, normative reasons to φ as facts (or truths) that count in favor of φ-ing is widely accepted. But are there any further conditions that considerations which count in favor of φ-ing must meet, in order to count as a reason to φ? In this brief paper, I consider and reject one such condition, recently proposed by Caspar Hare.     

Predicting Transitions in Low and High Levels of Risk Behavior from Early to Middle Adolescence: The TRAILS Study

The present study examined the joint development of substance use and externalizing problems in early and middle adolescence. First, it was tested whether the relevant groups found in previous studies i.e., those with an early onset, a late onset, and no onset or low levels of risk behavior could be identified, while using a developmental model of a single, underlying construct of risk behavior. Second, departing from Moffitt's taxonomy of antisocial behavior, it was tested if early, but not late, onset risk behavior is predicted by a problematic risk profile in childhood. Data were used from TRAILS, a population based cohort study, starting at age 11 with two follow-ups at mean ages of 13.6 and 16.3 years. Latent transition analyses demonstrated that, both in early and middle adolescence, a single underlying construct of risk behavior, consisting of two classes (labeled as low and high risk behavior), adequately represented the data. Respondents could be clearly classified into four possible transition patterns from early to middle adolescence, with a transition from high to low being almost non-existent (2.5 %), low to low (39.4 %) and low to high (41.8 %) being the most prevalent, and high to high (16.2 %) substantial. As hypothesized, only the high-high group was characterized by a clear adverse predictor profile in late childhood, while the low-high group was not. This study demonstrates that the development of substance use is correlated with externalizing problems and underscores the theory that etiologies of early and later onset risk behavior are different.     

Can Motivation Normalize Working Memory and Task Persistence in Children with Attention-Deficit/Hyperactivity Disorder? The Effects of Money and Computer-Gaming

Visual-spatial Working Memory (WM) is the most impaired executive function in children with Attention-Deficit/Hyperactivity Disorder (ADHD). Some suggest that deficits in executive functioning are caused by motivational deficits. However, there are no studies that investigate the effects of motivation on the visual-spatial WM of children with- and without ADHD. Studies examining this in executive functions other than WM, show inconsistent results. These inconsistencies may be related to differences in the reinforcement used. The effects of different reinforcers on WM performance were investigated in 30 children with ADHD and 31 non-ADHD controls. A visual-spatial WM task was administered in four reinforcement conditions: Feedback-only, 1 euro, 10 euros, and a computer-game version of the task. In the Feedback-only condition, children with ADHD performed worse on the WM measure than controls. Although incentives significantly improved the WM performance of children with ADHD, even the strongest incentives (10 euros and Gaming) were unable to normalize their performance. Feedback-only provided sufficient reinforcement for controls to reach optimal performance, while children with ADHD required extra reinforcement. Only children with ADHD showed a decrease in performance over time. Importantly, the strongest incentives (10 euros and Gaming) normalized persistence of performance in these children, whereas 1 euro had no such effect. Both executive and motivational deficits give rise to visual-spatial WM deficits in ADHD. Problems with task-persistence in ADHD result from motivational deficits. In ADHD-reinforcement studies and clinical practice (e.g., assessment), reinforcement intensity can be a confounding factor and should be taken into account. Gaming can be a cost-effective way to maximize performance in ADHD.
