Learning implicitly to produce avoided behaviours

The literature on repetition processing reveals an intriguing paradox between the particular salience of repetitions, which makes them easy to learn, and a tendency to avoid them when generating sequences. The aim of this experiment was to study the extent to which children can learn to produce these avoided behaviours by means of an artificial grammar paradigm using generation tests with implicit or explicit instructions. The analysis of the control group's performance confirmed the presence of a spontaneous tendency to avoid generating repetitions. A comparison with chance revealed that the children learned to produce repetitions in the explicit test but not in the implicit test. However, a comparison with the control group showed that learning nonetheless occurred in the experimental group with the implicit test. The discussion focused on this antirepetition behavioural bias and how it interacted with the type of information processes elicited by the tests selected for assessing implicit learning effects.     

Does length or neighborhood size cause the word length effect?

Jalbert, Neath, Bireta, and Surprenant (2011) suggested that past demonstrations of the word length effect, the finding that words with fewer syllables are recalled better than words with more syllables, included a confound: The short words had more orthographic neighbors than the long words. The experiments reported here test two predictions that would follow if neighborhood size is a more important factor than word length. In Experiment 1, we found that concurrent articulation removed the effect of neighborhood size, just as it removes the effect of word length. Experiment 2 demonstrated that this pattern is also found with nonwords. For Experiment 3, we factorially manipulated length and neighborhood size, and found only effects of the latter. These results are problematic for any theory of memory that includes decay offset by rehearsal, but they are consistent with accounts that include a redintegrative stage that is susceptible to disruption by noise. The results also confirm the importance of lexical and linguistic factors on memory tasks thought to tap short-term memory.     

When does length cause the word length effect?

The word length effect, the finding that lists of short words are better recalled than lists of long words, has been termed one of the benchmark findings that any theory of immediate memory must account for. Indeed, the effect led directly to the development of working memory and the phonological loop, and it is viewed as the best remaining evidence for time-based decay. However, previous studies investigating this effect have confounded length with orthographic neighborhood size. In the present study, Experiments 1A and 1B revealed typical effects of length when short and long words were equated on all relevant dimensions previously identified in the literature except for neighborhood size. In Experiment 2, consonant-vowel-consonant (CVC) words with a large orthographic neighborhood were better recalled than were CVC words with a small orthographic neighborhood. In Experiments 3 and 4, using two different sets of stimuli, we showed that when short (1-syllable) and long (3-syllable) items were equated for neighborhood size, the word length effect disappeared. Experiment 5 replicated this with spoken recall. We suggest that the word length effect may be better explained by the differences in linguistic and lexical properties of short and long words rather than by length per se. These results add to the growing literature showing problems for theories of memory that include decay offset by rehearsal as a central feature.     

Backward recall and the word length effect

The word length effect, the finding that words that have fewer syllables are recalled better than otherwise comparable words that have more syllables, is one of the benchmark effects that must be accounted for in any model of serial recall, and simulation models of immediate memory rely heavily on the finding. However, previous research has shown that the effect disappears when participants are asked to recall the items in strict backward order. The present 2 experiments replicate and extend that finding by manipulating the participant's foreknowledge of recall direction (Experiment 1) and by giving the participant repeated practice with one direction by blocking recall direction (Experiment 2). In both experiments, a word length effect obtained with forward but not backward recall. The results are problematic for all models that currently have an a priori explanation for word length effects. The finding can be accounted for but is not predicted by Scale-Independent Memory, Perception, and Learning (SIMPLE), a model in which item and order information are differentially attended to in the 2 recall directions.     

Family Support in Prevention Programs for Children at Risk for Emotional/Behavioral Problems

We conducted a review of empirically based prevention programs to identify prevalence and types of family support services within these programs. A total of 238 articles published between 1990 and 2011 that included a family support component were identified; 37 met criteria for inclusion. Following the Institute of Medicine’s typology, prevention programs were categorized as universal, selective, or indicated; programs containing more than one prevention level were characterized as multi-level. Family support types included those led by a mental health professional, led by a peer, or team-led. Among the 37 prevention programs reviewed, 27% (n = 10) were universal, 41% (n = 15) were selective, 16% (n = 6) were indicated, and 16% (n = 6) were multi-level. The predominant model of family support was professionally led (95%, n = 35). Two (n = 5%) provided team-led services. None were purely peer-led. In terms of content of family support services, all (100%, n = 37) provided instruction/skill build. Information and education was provided by 70% (n = 26), followed by emotional support (n = 11, 30%) and instrumental or concrete assistance (n = 11, 30%). Only 14% (n = 5) provided assistance with advocacy. The distribution of models and content of services in prevention studies differ from family support within treatment studies. As family support is likely to be an enduring component of the child and family mental health service continuum, comparative effectiveness studies are needed to inform future development.     

Artificial grammar learning in children: abstraction of rules or sensitivity to perceptual features?

We examined sensitivity to grammatical sequences of colors in an artificial grammar learning task in a sample of 120 children aged between 5 and 8 years. The aim of the experiment was to test whether the children would preferentially learn the specific salient features of the items they were exposed to or the rules that generated these items. The children were divided into two experimental groups (identical grammar but training items differing in their surface features) and a control group (random items). The results showed that regardless of age, participants learned the most frequent salient features of the items, as well as some kind of abstract relational information. However, the 8-year-olds presented a more complex result profile, with one of the experimental groups apparently developing sensitivity to grammatical rules. These results are discussed with reference to the main current models of implicit learning. Overall, the results provided more support for stimulus-specific processing models than for rule-based models.     

Adaptation and Acculturation: Experiences of Internationally Educated Social Workers

Transnational mobility of internationally educated social workers has been on the rise for the past 20 years, with little empirical study regarding their experiences of professional adaptation. This paper contextualises and presents data from a study with 15 social workers who undertook their professional education outside Canada and have migrated to Canada within the past 10 years, regarding their professional acculturation and adaptation. The analysis focuses on elements that facilitated and mitigated their professional acculturation and the resulting adaptations participants have experienced in their practice in the Canadian context. The paper's discussion outlines the importance of a stronger grounding in professional values of social work in order to facilitate professional acculturation and adaptation of internationally educated social workers.     

Mood Induction in Children: Effect of the Affective Valence of a Text on Phonological Working Memory

The influence of mood on working memory capacity has been investigated in adults, albeit with conflicting results, but remains relatively unexplored in children. The present study examined the effect of a mood induction procedure on phonological working memory capacity in fourth and fifth graders. An initial working memory span test was followed first by a collective mood induction procedure, then by a second working memory span test. Results showed an effect of mood induction procedure on phonological working memory performances, with decreasing scores in the case of negative mood. These results suggest that, in certain contexts and situations, negative emotion has an impact on children’s cognitive abilities.     

Critical reading effort during text revision

This study concerns one of the processes involved in written verbal production: text revising. Our aim was to experimentally test the specificity of reading for revision as compared to reading for comprehension, and to determine the cognitive cost of initiating and performing critical-reading processes. A two-session experiment was conducted on students who had to perform a comprehension task and a revising task on a text presented in its basic version, or in a version containing either syntax errors or spelling errors. An analysis of the cognitive effort associated with critical-reading and comprehension-reading processes, and of the participants’ comprehension and revising performance, showed that critical reading was more effortful than comprehension reading. It showed also that critical reading was more effortful for the text version with syntax errors than with spelling mistakes. In addition, the working memory span of the readers/revisers had a different impact on effort and performance, depending on the type of errors in the text (spelling or syntax).     

Mother–Infant Joint Attention and Sharing: Relations to Disorganized Attachment and Maternal Disrupted Communication

The normative development of infant shared attention has been studied extensively, but few studies have examined the impact of disorganized attachment and disturbed maternal caregiving on mother–infant shared attention. The authors examined both maternal initiations of joint attention and infants’ responses to those initiations during the reunion episodes of the Strange Situation Procedure at 12 and 18 months of infant age. The mothers' initiations of joint attention and three forms of infant response, including shunning, simple joint attention, and sharing attention, were examined in relation to infant disorganized attachment and maternal disrupted communication. Mothers who were disrupted in communication with their infants at 18 months initiated fewer bids for joint attention at 12 months, and, at 18 months, mothers of infants classified disorganized initiated fewer bids. However, the infant' responses were unrelated to either the infant' or the mother' disturbed attachment. At both ages, disorganized infants and infants of disrupted mothers were as likely to respond to maternal bids as were their lower risk counterparts. Our results suggest that a disposition to share experiences with others is robust in infancy, even among infants with adverse attachment experiences, but this infant disposition may depend on adult initiation of bids to be realized.
