Computational Evidence That Frequency Trajectory Theory Does Not Oppose But Emerges From Age‐of‐Acquisition Theory

According to the age‐of‐acquisition hypothesis, words acquired early in life are processed faster and more accurately than words acquired later. Connectionist models have begun to explore the influence of the age/order of acquisition of items (and also their frequency of encounter). This study attempts to reconcile two different methodological and theoretical approaches (proposed by Lambon Ralph & Ehsan, 2006 and Zevin & Seidenberg, 2002 ) to age‐limited learning effects. The current simulations extend the findings reported by Zevin and Seidenberg (2002) that have shown that frequency trajectories (FTs) have limited and specific effects on word‐reading tasks. Using the methodological framework proposed by Lambon Ralph and Ehsan (2006) , which makes it possible to compare word‐reading and picture‐naming tasks in connectionist networks, we were able to show that FT has a considerable influence on age‐limited learning effects in a picture naming task. The findings show that when the input–output mappings are arbitrary (simulating picture naming tasks), the links formed by the network become entrenched as a result of early experience and that subsequent variations in frequency of exposure of the items have only a minor impact. In contrast, when the mappings between input‐output are quasi‐systematic or systematic (simulating word‐reading tasks), the training of new items was generalized and resulted in the suppression of age‐limited learning effects. At a theoretical level, we suggest that FT, which simultaneously takes account of time and the level of exposure across time, represents a more precise and modulated measure compared with the order of introduction of the items and may lead to innovative hypotheses in the field of age‐limited learning effects.     

Suggestion does not de-automatize word reading: Evidence from the semantically based Stroop task

Recent studies have shown that the suggestion for participants to construe words as meaningless symbols reduces, or even eliminates, standard Stroop interference in highly suggestible individuals (Raz, Fan, & Posner, 2005; Raz, Kirsch, Pollard, & Nitkin-Kaner, 2006). In these studies, the researchers consequently concluded that this suggestion de-automatizes word reading. The aim of the present study was to closely examine this claim. To this end, highly suggestible individuals completed both standard and semantically based Stroop tasks, either with or without a suggestion to construe the words as meaningless symbols (manipulated in both a between-participants [Exp. 1] and a within-participants [Exp. 2] design). By showing that suggestion substantially reduced standard Stroop interference, these two experiments replicated Raz et al.'s (2006) results. However, in both experiments we also found significant semantically based Stroop effects of similar magnitudes in all suggestion conditions. Taken together, these results indicate that the suggestion to construe words as meaningless symbols does not eliminate, or even reduce, semantic activation (assessed by the semantically based Stroop effect) in highly suggestible individuals, and that such an intervention most likely reduces nonsemantic task-relevant response competition related to the standard Stroop task. In sum, contrary to Raz et al.'s claim, suggestion does not de-automatize or prevent reading (as shown by a significant amount of semantic processing), but rather seems to influence response competition. These results also add to the growing body of evidence showing that semantic activation in the Stroop task is indeed automatic.     

The influence of mere social presence on Stroop interference: New evidence from the semantically-based Stroop task

Several studies have shown that mere social presence reduces Stroop interference but processes underlying such effect are still poorly understood. Given that the standard Stroop task used in those studies confounds semantic and response competition, it remains unclear whether Stroop words are processed normally (Sharma, Booth, Brown, & Huguet, 2010) or whether the processing of their semantic representations is altered (Huguet, Galvaing, Monteil, & Dumas, 1999, Exp. 1). The direct evidence from the semantically-based Stroop task (i.e., a task that is free of response competition and thus isolates the semantic component of the Stroop interference, Neely & Kahan, 2001) provided in this paper attests normal semantic processing. Such result refutes the idea that semantic activation can be prevented or controlled by social presence and thus adds to the growing body of evidence showing that semantic activation is indeed automatic. Also importantly, this paper offers an alternative explanation of past findings, which holds that social presence simply reduces the response competition that occurs in the standard Stroop task and sheds some light on the processes that underlie social-facilitating effects of mere presence in the Stroop task.     

Swedish pupils' suggested coping strategies if cyberbullied: Differences related to age and gender

The aim of this study was to investigate the coping strategies that Swedish 10 and 12 year‐olds (N = 694) suggested they would use if they were cyberbullied, with a special focus on whether there are differences in these strategies related to age and gender. The most commonly suggested coping strategy was telling someone, especially parents and teachers (70.5%). Surprisingly few of the pupils reported that they would tell a friend (2.6%). Differences in suggested coping strategies were found related to age and gender. Findings are discussed in relation to the Swedish sociocultural context as well as in relation to the implications for prevention strategies against cyberbullying.     

Three-dimensional features facilitate object recognition

Abstract

A priming paradigm was used to investigate the contribution of local features and global shape information in object recognition. Five types of incomplete forms were used as primes: (1) forms with both maxima (local curvature) and midsegments of edges present and aligned on the outline contour; (2) forms similar in global shape to the first version of stimuli, but with misaligned elements; (3) forms with only maxima; (4) forms with only midsegments of edges; and (5) forms containing 3D comer junctions (in Experiments 3 and 4). The target was an outline drawing of an object from which the incomplete prime was derived. Subjects were asked to name the target as rapidly as possible. Primes were presented at levels of contrast corresponding to identification thresholds, as well as above and below threshold levels (determined in Experiments 1 and 3). Facilitation effects relative to a neutral (no prime) condition occurred at threshold and above threshold for primes with aligned elements, forms with only maxima, and forms with only midsegments. Priming occurred only above threshold for forms with non-aligned elements. In Experiment 4 the presence of 3D local features increased the magnitude of priming relative to forms with midsegments and to forms with flat corners (in Experiment 2). This result suggests that 3D features facilitate object identification either because objects are stored in the form of volumetric entities or because 3D features are extracted early in visual processing.     

Children's narratives and well-being

Research with adults indicates that writing causal-explanatory and emotionally disclosing narratives of stressful experiences is related to psychological well-being. Limited research with children has shown mixed results, but developmental theory suggests that simple extrapolation from adult findings might be problematic. In this study, 9- to 13-year-old children engaged in three days of writing under emotional and non-emotional instructions, and completed measures of depression, anxiety, strengths and difficulties, and somatic symptoms both at baseline and 2 months following intervention. Narratives were coded using a developmentally appropriate, exhaustive coding system. Children in the emotional writing group wrote more about negative evaluations, problems, emotions, explanations and coping than children in the non-emotional writing group. However, those children who wrote more about negative evaluations, problems and explanations subsequently showed higher levels of anxiety, depression and difficulties. Due to limited narrative and emotional regulation skills, expressive writing may not benefit, and may even be detrimental for, some children.     

Family narrative interaction and children's sense of self

Family narratives about the shared past may be a particularly significant site for preadolescents' emerging sense of self both as an individual and as a member of a unified family. We examined the relations between family narrative interaction style when reminiscing and preadolescents' sense of self. Results indicated three narrative interaction styles that describe the extent to which families discuss or fail to discuss their past in integrated and validating ways. Specifically, conversations with a coordinated perspective incorporated information from all members and were related to higher self-esteem, especially in girls. Conversations with an individual perspective, in which family members took turns telling their thoughts and feelings about the event without integration among the perspectives, were associated with a more external locus of control, especially in boys. Conversations with an imposed perspective, in which one family member was in charge of the conversation or in which unpleasant exchanges between members occurred, were not associated with either self-esteem or locus of control. Implications of these narrative interaction styles for children's developing sense of self are discussed.

Effects of orthography are independent of phonology in masked form priming

Briefly presented forward-masked primes that share letters with a word target have been shown to facilitate performance in different word recognition tasks. However, in all the experiments that have previously reported these facilitatory effects, related primes not only shared more letters with the target than did unrelated primes (orthographic priming), but they also shared more phonemes (phonological priming). The stimuli used in the present experiments allow us to separate out the effects of orthographic priming from phonological priming. Varying prime exposure duration from 14 to 57 msec, it is shown that effects of orthography follow a distinct time-course from the effects of phonology, and that orthographic facilitation does not result from a confound with phonological prime-target overlap.
