Influence of Background Speech and Music in Interrupted Reading: An Eye‐Tracking Study

The current study examined the influence of interruption, background speech and music on reading, using an eye movement paradigm. Participants either read paragraphs while being exposed to background speech or music or read the texts in silence. On half of the trials, participants were interrupted by a 60‐second audio story before resuming reading the paragraph. Interruptions increased overall reading time, but the reading of text following the interruption was quicker compared with baseline. Background speech and music did not modulate the interruption effects, but the background speech slowed down the reading rate compared with reading in the presence of music or reading in silence. The increase in reading time was primarily due to an increase in the time spent rereading previously read words. We argue that the observed interruption effects are in line with a theory of long‐term working memory, and we present practical implications for the reported background speech effects.

Formula: see text]Executive functions in extremely low birth weight and late-preterm preschoolers: Effects on working memory and response inhibition

Executive function (EF) refers to fundamental capacities that underlie more complex cognition and have ecological relevance across the individual's lifespan. However, emerging executive functions have rarely been studied in young preterm children (age 3) whose critical final stages of fetal development are interrupted by their early birth. We administered four novel touch-screen computerized measures of working memory and inhibition to 369 participants born between 2004 and 2006 (52 Extremely Low Birth Weight [ELBW]; 196 late preterm; 121 term-born). ELBW performed worse than term-born on simple and complex working memory and inhibition tasks and had the highest percentage of incomplete performance on a continuous performance test. The latter finding indicates developmental immaturity and the ELBW group's most at-risk preterm status. Additionally, late-preterm participants performed worse compared with term-born on measures of complex working memory but did not differ from those term-born on response inhibition measures. These results are consistent with a recent literature that identifies often subtle but detectable neurocognitive deficits in late-preterm children. Our results support the development and standardization of computerized touch-screen measures to assess EF subcomponent abilities during the formative preschool period. Such measures may be useful to monitor the developmental trajectory of critical executive function abilities in preterm children, and their use is necessary for timely recognition of deficit and application of appropriate interventional strategies.     

Spousal similarity in depression: a dyadic latent panel analysis of the panel study of Belgian households

Dyadic latent panel analysis (DLPA) was applied to eight waves of the Panel Study of Belgium Households (N = 954 couples). DLPA decomposes the observed variance of both members of a dyad into variance due to stable factors, factors that gradually change over time, and occasion-specific factors including random error. Total observed similarity between members of a dyad on one occasion is decomposed into stable similarity, similarity in factors that change over time, and occasion-specific similarity. The results show that depressive symptoms are influenced by stable and changing factors and that spousal similarity in both factors contribute to spousal similarity in depression on a single occasion. Spousal similarity in factors that change gradually over time suggests that shared-environmental factors contribute to depressive symptoms.     

Rumination mediates the prospective effect of low self-esteem on depression: a five-wave longitudinal study

Previous research supports the vulnerability model of low self-esteem and depression, which states that low self-esteem operates as a prospective risk factor for depression. However, it is unclear which processes mediate the effect of low self-esteem. To test for the mediating effect of rumination, the authors used longitudinal mediation models, which included exclusively prospective effects and controlled for autoregressive effects of the constructs. Data came from 663 individuals (aged 16 to 62 years), who were assessed 5 times over an 8-month period. The results indicated that low self-esteem predicted subsequent rumination, which in turn predicted subsequent depression, and that rumination partially mediated the prospective effect of low self-esteem on depression. These findings held for both men and women, and for both affective-cognitive and somatic symptoms of depression. Future studies should test for the mediating effects of additional intrapersonal and interpersonal processes.     

Metacognitive inferences in source memory judgements: the role of perceived differences in item recognition

This research investigated the hypothesis that metacognitive inferences in source memory judgements are based on the recognition or nonrecognition of an event together with perceived or expected differences in the recognizability of events from different sources. The hypothesis was tested with a multinomial source-monitoring model that allowed separation of source-guessing tendencies for recognized and unrecognized items. Experiments 1A and 1B manipulated the number of item presentations as relevant source information and revealed differential guessing tendencies for recognized and unrecognized items, with a bias to attribute unrecognized items to the source associated with poor item recognition. Experiments 2A and 2B replicated the findings with a manipulation of presentation time and extended the analysis to subjective differences in item recognition. Experiments 3A and 3B used more natural source information by varying type of acoustic signal and demonstrated that subjective theories about differences in item recognition are sufficient to elicit differential source-guessing biases for recognized and unrecognized items. Together the findings provide new insights into the cognitive processes underlying source memory decisions, which involve episodic memory and reconstructive tendencies based on metacognitive beliefs and general world knowledge.     

Pleasure,displeasure, and mixed feelings: Are semantic opposites mutually exclusive?

Are pleasure and displeasure opposite markers of a single dimension, or are pleasure and displeasure two separate feelings? The present article argues that the existing evidence proved inconclusive for four reasons: (a) assessment of affect in unspecified situations, (b) assessment of affect at one moment in time, (c) use of inappropriate statistics, and (d) lack of theoretical predictions. The present article presents a study in which affect was assessed before and after an induction of mild displeasure via unpleasant pictures. Furthermore, pleasure and displeasure ratings are compared to ratings of feeling hot and cold. Results indicate that hot and cold ratings represent opposite ends of a single hot-cold dimension. Pleasure ratings could not be represented along a single pleasure-displeasure dimension. Methodological implications for future research on the structure of affect are discussed.
