Understanding the centrality deficit: Insight from foreign language learners

This study replicated and extended a phenomenon in the text memory literature referred to as the centrality deficit Miller & Keenan (Annals of Dyslexia 59:99–113, 2009). It examined how reading in a foreign language (L2) affects one’s text representation and ability to recall the most important information. Readers recalled a greater proportion of central than of peripheral ideas, regardless of whether reading in their native language (L1) or a foreign language (L2). Nonetheless, the greatest deficit in participants’ L2 recalls, as compared with L1 recalls, was on the central, rather than the peripheral, information. This centrality deficit appears to stem from resources being diverted from comprehension when readers have to devote more cognitive resources to lower level processes (e.g., L2 word identification and syntactic processing), because the deficit was most evident among readers who had lower L2 proficiency. Prior knowledge (PK) of the passage topic helped compensate for the centrality deficit. Readers with less L2 proficiency who did not have PK of the topic displayed a centrality deficit, relative to their L1 recall, but this deficit dissipated when they did possess PK.     

Equanimity to Excess: Inhibiting the Expression of Negative Emotion is Associated with Depression Symptoms in Girls

Emotion dysregulation is often invoked as an important construct for understanding risk for psychopathology, but specificity of domains of emotion regulation in clinically relevant research is often lacking. In the present study Gross’ (2001) model of emotion regulation is used to generate hypotheses regarding the relative contribution of two specific types of deficits in emotion regulation, inhibited and disinhibited expression of negative emotion, to individual differences in depressive symptoms in preadolescent girls. A sample of 232 9-year-old girls was recruited from a community based study. Depression symptoms were assessed via diagnostic interview. The mother and interviewer rated the girl’s level of impairment. Questionnaires and observations were used to assess inhibited and disinhibited expression of negative emotion. Differences in inhibited expression of negative emotion typically explained more variance in depressive symptoms and impairment across informants than did disinhibited expression of negative emotion. Although disinhibited expression of negative emotion is associated with depression and impairment, inhibited expression appeared to be a necessary ingredient, suggesting that inhibited expression may be a particularly relevant deficit in emotion regulation in the development of depression in females.     

Negative affect predicts performance on an object permanence task

Recent research has demonstrated a strong connection between an infant’s ability to regulate their affective states and their attentional processes. In particular, negative affect can disrupt attention to the environment. In the object permanence literature, attention has been implicated as a factor in performance on the A‐not‐B task, yet factors that may disrupt attention, such as negative affect, have been largely ignored as a possible factor which predicts correct search. In the present study, we examined the effects of negative affect and attention on correct search performance for a sample of 36 9‐month‐old infants in a two location A‐not‐B task with a 5‐second delay between hiding and search. Infants’ levels of negative affect and attention to the task were coded on the third A trial of the A‐not‐B task. It was predicted that infants who searched incorrectly on the B trial would show high levels of negative affect and low levels of attention whereas infants who searched correctly would show the opposite pattern and furthermore, that negative affect would mediate the association between attention and search performance. The results of the study supported the hypotheses and are taken as indicating the importance of emotion‐cognition interactions in the development of cognitive competence.     

Imagery in the congenitally blind: how visual are visual images?

Three experiments compared congenitally blind and sighted adults and children on tasks presumed to involve visual imagery in memory. In all three, the blind subjects' performances were remarkably similar to the sighted. The first two experiments examined Paivio's (1971) modality-specific imagery hypothesis. Experiment 1 used a paired-associate task with words whose referents were high in either visual or auditory imagery. The blind, like the sighted, recalled more high-visual-imagery pairs than any others. Experiment 2 used a free-recall task for words grouped according to modality-specific attributes, such as color and sound. The blind performed as well as the sighted on words grouped by color. In fact, the only consistent deficit in both experiments occurred for the sighted in recall of words whose referents are primarily auditory. These results challenge Paivio's theory and suggest either (a) that the visual imagery used by the sighted is no more facilitating than the abstract semantic representations used by the blind or (b) that the sighted are not using visual imagery. Experiment 3 used Neisser and Kerr's (1973) imaging task. Subjects formed images of scenes in which target objects were described as either visible in the picture plane or concealed by another object and thus not visible. On an incidental recall test for the target objects, the blind, like the sighted, recalled more pictorial than concealed targets. This finding suggests that the haptic images of the blind maintain occlusion just as the visual images of the sighted do.     

Me, myself, and lie: The role of self-awareness in deception

Deception has been studied extensively but still little is known about individual differences in deception ability. We investigated the relationship between self-awareness and deception ability. We enlisted novice actors to portray varying levels of deception. Forty-two undergraduates viewed the videotaped portrayals and rated the actors’ believability. Actors with high private self-awareness were more effective deceivers, suggesting that high self-monitors are more effective at deceiving. Self-awareness may lead to knowledge of another’s mental state (i.e., Theory of Mind), which may improve an individual’s deception ability.     

Text processing and feedback: what have we learned?

In studies on the effects of feedback on text comprehension, it was determined that text content interacts differentially with the feedback provided. Specifically, the types of memorial representations sought must be considered in terms of type of text, feedback timing, frequency, and modality.     

Word list generation performance in Alzheimer's disease and vascular dementia

Word list generation (WLG) was examined among clinical samples of individuals with Alzheimer's disease (AD) (n = 73) or ischemic vascular dementia (IVD) (n = 85), equivalent in age, education, current and estimated premorbid intellectual functioning, and proportion of men and women. The AD group performed significantly better than did the IVD group on lexical WLG, and a trend was observed indicating superior performance among the IVD group on categorical WLG. Within-groups, comparisons of group means, and profile analyses of individual performance patterns all indicated that persons with AD demonstrated a lexical > categorical pattern significantly more often than did IVD participants. The absolute difference in average performance between the AD and IVD groups on lexical and categorical WLG was small; the findings, however, generally support the clinical utility of the lexical > categorical WLG pattern in the differential diagnosis of AD and IVD. The patterns of performance support the presence of relative impairment in semantic processing among the individuals with AD and global deficits in retrieval and processing speed in individuals with IVD.     

"Whose perfection is it anyway?": a virtuous consideration of enhancement.

Discussions of genetic enhancements often imply deep suspicions about human desires to manipulate or enhance the course of our future. These unspoken assumptions about the arrogance of the quest for perfection are at odds with the normally hopeful resonancy we find in contemporary theology. The author argues that these fears, suspicions and accusations are misplaced. The problem lies not with the question of whether we should pursue perfection, but rather what perfection we are pursuing. The author argues that perfection, properly understood, has an enormously positive function in the Roman Catholic tradition. The author examines three sources: the Scriptures, the scholastic tradition, and ascetical theology. He examines contemporary criticisms of perfectionism and suggests that an adequate virtue theory keeps us from engaging perfectionism as such. The author then shows how a positive, responsible view of perfection is an asset to our discussion on enhancement technology.     

Evidence for the Continuity of Early Problem Behaviors: Application of a Developmental Model

Evidence of the continuity of early problem behaviors in young girls and boys was examined developmentally. Data were gathered on 104 mother-child dyads from low-income families when children were between 1 and 5 years of age. Difficult temperament, aggression, and noncompliance from 12 to 24 months, and externalizing and internalizing problems at 36 and 60 months, were assessed. The results provide evidence for the continuity of early behavioral and emotional problems and support for the early differentiation between internalizing and externalizing problems. Implications of the current findings for prevention efforts are presented.     

DEVELOPING FLUENCY AND ENDURANCE IN A CHILD DIAGNOSED WITH ATTENTION DEFICIT HYPERACTIVITY DISORDER

We examined the effect of a teaching method on skill fluency and on‐task endurance of a 9‐year‐old boy who had been diagnosed with attention deficit hyperactivity disorder. An academic task that occurred at low fluency during 10‐min baseline sessions was taught to fluency. When responding was not yet fluent, brief reversals to baseline showed that the learner's rate of responding decreased and that he did not spend entire sessions on task. However, once a fluency goal had been reached, responding remained fluent and he remained on task in the third reversal condition.
