Is problem solving dependent on language?

There has been a long-standing debate in the fields of philosophy and cognitive science surrounding the relationship of language to cognition, but the exact nature of this relationship is still unclear (Sokolov, 1968/1972). In the current study, we explored the role of language in one aspect of cognition, namely problem solving, by administering the Wisconsin Card Sorting Test (WCST) to stroke patients with varying degrees of language impairment (Experiment 1) and to normal participants under conditions of articulatory suppression (Experiment 2). In Experiment 1, there was a significant correlation between performance on the WCST and language measures such as comprehension and naming. Demonstrating the specificity of this result, we also found a significant relationship between language performance and another test of problem solving, the Raven's Colored Progressive Matrices, but no relationship between language and a test of visuospatial functioning. In Experiment 2, normal participants were significantly impaired on the WCST under conditions of articulatory suppression, relative to a baseline condition. Together, these findings suggest that language plays a role in complex problem solving, possibly through covert language processes.     

Context extinction and associative learning in Lymnaea

Aerial respiratory behavior in the pond snail Lymnaea was operantly conditioned so that snails learned not to perform aerial respiration in a hypoxic environment. Snails were trained in either the standard context (no food odorant) or a carrot (food-odorant) context. An operant training procedure of two 45-min training sessions with a 1-h interval between the sessions followed by a third 45-min training session 18 h later was sufficient to produce associative learning and long-term memory (LTM) that persisted for at least 5 days. If, however, following the third operant training session snails received three 45-min extinction training sessions, with each extinction session separated by at least a 1-h interval, LTM was not observed when tested the following day. That is, the memory was extinguished. Extinction, however, did not occur if the context of the extinction training was different from the context of the associative training. That is, in the snails trained in the standard context, extinction did not occur if the extinction training sessions were performed in the food-odorant context and vice versa.     

Thinking too much: How young people experience rumination in the context of loneliness

The recent rise in the prevalence of loneliness, particularly among young adults, coupled with its deleterious effects on wellbeing, makes understanding the issue of pressing concern. As most research on loneliness has focused on older adults, this study explored how 48 young adults aged 18–24 subjectively experienced loneliness through free association-based interviews. Participants were sampled from the four most deprived boroughs in London, as area deprivation has been associated with a higher prevalence of loneliness. This facilitates understanding of contributors and consequences of loneliness within this demographic group. In particular, the focus is on rumination arising from loneliness; while the link between the two is well-established quantitively, research into rumination and the context of ruminative thoughts in the context of loneliness remains sparse. Thus, this study aimed to understand the subjective experience of rumination in young adults whilst they experienced loneliness. Thematic analysis of interviews using ATLAS.ti 9 revealed five themes capturing these experiences: ‘temporal experience of rumination’, ‘ruminating life and death’, ‘rumination related to others’, ‘outcomes of rumination’ and ‘coping with loneliness-related rumination’. Based upon knowledge of the nature and content of rumination, further research could devise models of rumination and interventions targeted at rumination such as mindfulness meditation, journaling and engaging in prosocial behaviour, to mitigate the adverse effects loneliness can have on wellbeing.     

Here's looking at you,kid: attention to infant emotional faces in mothers and non‐mothers

Infant facial cues play a critical role in eliciting care and nurturance from an adult caregiver. Using an attentional capture paradigm we investigated attentional processing of adult and infant emotional facial expressions in a sample of mothers (n = 29) and non‐mothers (n = 37) to determine whether infant faces were associated with greater task interference. Responses to infant target stimuli were slower than adult target stimuli in both groups. This effect was modulated by parental status, such that mothers compared to non‐mothers showed longer response times to infant compared to adult faces. Both groups also responded more slowly to emotional faces, an effect that was more marked for infant emotional faces. Finally, it was found that greater levels of mothers' self‐reported parental distress was associated with less task interference when processing infant faces. These findings indicate that for adult women, infant faces in general and emotional infant faces in particular, preferentially engage attention compared to adult faces. However, for mothers, infant faces appear to be more salient in general. Therefore, infant faces may constitute a special class of social stimuli. We suggest that alterations in attentional processing in motherhood may constitute an adaptive behavioural change associated with becoming a parent.     

Detecting racial identification: The role of phenotypic prototypicality

Little is known about what cues are used to infer the racial identification of others and whether or not identification inferences are accurate. Three studies provide evidence that phenotypic prototypicality (PP), the degree to which an individual looks like a prototypical member of his or her racial group, shapes inferences about racial identification. Participants assumed that high PP Blacks were more racially identified than low PP Blacks. In addition to serving as an identification cue for observers, PP was related to self-perceptions, as Blacks and Latinos who were higher in PP were in fact more identified with their racial group than minorities who were lower in PP. Furthermore, unacquainted judges accurately detected Black and Latino targets' racial identification based on PP. The results are discussed in terms of their implications for intergroup relationships.     

Quality home visits: Activities to promote meaningful interactions

Examination of and support for specific practices that promote high-quality home visiting are essential as family support programs continue to expand across the country. The current study used direct observation of 91 home visits across 41 home visitors to examine relations among interaction partners, content of the interactions, the home-visitors’ activities, and quality of home-visitors’ practices and family-members’ engagement within programs funded by the Maternal, Infant, and Early Childhood Home Visiting program. More time spent in triadic interactions focused on child-related content, as measured by the Home Visit Rating Scale-Revised, was related to higher quality of family engagement in home visits, as measured with the Home Visit Observation Rating Scales. Time spent in adult-focused interactions and administrative tasks, however, was related to lower quality of home-visiting practices and family engagement. Implications for research and practice are discussed.
