Memory for words location in writing

In two experiments, we investigated memory for words location after writing a text. Experiment 1 demonstrated the existence of a memory for words location in writing by showing that participants who first composed a text and were then asked to locate words extracted from their text performed above a chance level established using a computer simulation, and better than participants who did not compose a text but were told the subject of the text. Experiment 2 showed that memory for words location in writing is mainly supported by a visuospatial representation of the text, as indicated by the lower recall of words location by participants who performed a visuospatial concurrent task at the time of the composition, compared with participants who performed a verbal concurrent task. The findings highlight the role of a spatial representation of the physical layout of the text and the role of such a memory in the writing process.

Cognitive effort during note taking

Note taking is a complex activity that requires comprehension and selection of information and written production processes. Here we review the functions, abbreviation procedures, strategies, and working memory constraints of note taking with the aim of improving theoretical and practical understanding of the activity. The time urgency of selecting key points and recording them while comprehending new information at the same time places significant demands on the central executive and other components of working memory. Dual‐ and triple‐task procedures allow the measurement of the momentary cognitive effort or executive attention allocated to note taking. Comparative data show that note taking demands more effort than reading or learning. However, it requires less effort than the creative written composition of an original text.

Comparison of behavioral intervention and sensory integration therapy on challenging behavior of children with autism

The current study used an AB crossover design to directly compare the effects of sensory integration therapy (SIT) and behavioral intervention (BI) on the challenging behavior of 10 participants with autism spectrum disorder. During the intervention phase, all participants received both treatments. Follow‐up probes were conducted 1 month following intervention for 4 participants implementing the more effective intervention. The results showed that BI successfully reduced challenging behavior to low‐ or near‐zero levels. In contrast, SIT resulted in higher and more variable rates of challenging behavior. One exception was noted for Participant 4 who engaged in a decreased level of challenging behavior during SIT. The findings are discussed in relation to implication for practice and future research.     

Suppressing visual feedback in written composition: Effects on processing demands and coordination of the writing processes

The goal of this experiment was to investigate the role of visual feedback during written composition. Effects of suppression of visual feedback were analyzed both on processing demands and on on‐line coordination of low‐level execution processes and of high‐level conceptual and linguistic processes. Writers composed a text and copied it either with or without visual feedback. Processing demands of the writing processes were evaluated with reaction times to secondary auditory probes, which were analyzed according to whether participants were handwriting (in a composing and a copying task) or engaged in high‐level processes (when pausing in a composing task). Suppression of visual feedback increased reaction time interference (secondary reaction time minus baseline reaction time) during handwriting in the copying task and not during pauses in the composing task. This suggests that suppression of visual feedback only affected processing demands of execution processes and not those of high‐level conceptual and linguistic processes. This is confirmed by analysis of the quality of the texts produced by participants, which were little, if at all, affected by the suppression of visual feedback. Results also indicate that the increase in processing demands of execution related to suppression of visual feedback affected on‐line coordination of the writing processes. Indeed, when visual feedback was suppressed, reaction time interferences associated with handwriting were not reliably different in the copying task or the composing task but were significantly different when visual feedback was not suppressed: They were lower in the copying task than in the composition task. When visual feedback was suppressed, writers activated step‐by‐step execution processes and high‐level writing processes, whereas they concurrently activated these writing processes when composing with visual feedback.     

Execution and pauses in writing narratives: processing time, cognitive effort and typing skill

At the behavioural level, the activity of a writer can be described as periods of typing separated by pauses. Although some studies have been concerned with the functions of pauses, few have investigated motor execution periods. Precise estimates of the distribution of writing processes, and their cognitive demands, across periods of typing and pauses are lacking. Furthermore, it is uncertain how typing skill affects these aspects of writing. We addressed these issues, selecting writers of low and high typing skill who performed dictation and composition tasks. The occurrences of writing processes were assessed through directed verbalization, and their cognitive demands were measured through interference in reaction times (IRT). Before writing a narrative, 34 undergraduates learned to categorize examples of introspective thoughts as different types of activities related to writing (planning, translating, or revising). Then, while writing, they responded to random auditory probes, and reported their ongoing activity according to the learned categories. Convergent with previous findings, translating was most often reported, and revising and planning had fewer occurrences. Translating was mostly activated during motor execution, whereas revising and planning were mainly activated during pauses. However, none of the writing processes can be characterized as being typical of pauses, since translating was activated to a similar extent as the other two processes. Regarding cognitive demands, revising is likely to be the most demanding process in narrative writing. Typing skill had an impact on IRTs of motor execution. The demands of execution were greater in the low than in the high typing skill group, but these greater demands did not affect the strategy of writing processes activation. Nevertheless, low typing skill had a detrimental impact on text quality.     

Verbal, visual, and spatial working memory in written language production

College students wrote definitions of either abstract or concrete nouns in longhand while performing a concurrent working memory (WM) task. They detected either a verbal (syllable), visual (shape), or spatial (location) stimulus and decided whether it matched the last one presented 15-45s earlier. Writing definitions of both noun types elevated the response time to verbal targets above baseline. Such interference was observed for visual targets only when defining concrete nouns and was eliminated entirely with spatial targets. The interference effect for verbal targets was the same whether they were read or heard, implicating phonological storage. The findings suggest that language production requires phonological or verbal WM. Visual WM is selectively engaged when imaging the referents of concrete nouns.     

Perceptions of sugar mommy practices in South Africa

The study sought to explore sugar mommy practices regarding their occurrence, acceptability as well as perceived reasons why older women and younger men enter into sugar mommy relationships. An exploratory qualitative study involving 135 participants from 11 diverse focus groups in terms of age, gender (females=27%) and geotype throughout the nine South African provinces was conducted. Data on the participants’ views, opinions and experiences of sugar mommy practices were collected using focus group interviews. The data were thematically analyzed. The study found that sugar mommy practices were prevalent in South Africa. The perceived reasons for acceptability were: love, survival, and correctness. Perceived reasons why older women have sexual relationships with younger men included: sexual fulfilment, domination, reduction of stress, physical attraction, procreation, lack of self-control, youthful feeling, migrancy, difficulty in finding partners of compatible age and young men being seen as not demanding. Perceived reasons why younger men have sexual relationships with older women included: material gain, reduction of stress, being enticed, rejection by women of compatible age, peer influence and belief that older women are purer. Given the increase in sugar mommy practices, which may have significant implications for the prevalence of HIV/AIDS, it is necessary to understand the underlying perceptions of these practices, in order to develop culturally relevant and socially acceptable intervention programmes.
