Social-Psychological Origins of Feelings of Presence: Creating Social Presence With Machine-Generated Voices

Two experiments were conducted to test several questions regarding very young children's (6–24 months) learning (i.e., simple action imitation and word learning) from video. Specifically, this study tested the video deficit, which is the tendency for infants and toddlers to learn significantly more effectively from live information than they do when identical information is presented on a screen. First, the video deficit was explored using two different tasks. Overall, the pattern of results was similar for action imitation and word learning. Specifically, the video deficit was present for both simple action imitation and for word learning in the middle cohort, but not present for younger and older children. Second, there was some mitigation of the video deficit from seeing socially meaningful actors for action imitation; however for word learning the effect only approached significance. Third, repetition helped children learn words more effectively, especially for the youngest and oldest cohort; however, repetition did not help for simple task imitation.     

Computerized tabletop games as a form of a video game training for old-old

This research aimed at investigating the utility of a computerized version of a cognitively stimulating activity as a video game intervention for elderly. The study focused on the effect of a 6-week extensive practice intervention on aspects of cognitive functioning (vigilance, working memory (WM), inhibition, reasoning) of old-old participants (N = 29), randomly assigned to trained or active control group. The difference between groups was in the content of the extended video game practice – cognitively complex card game for trained and computerized version of a simple dice-game of chance for control participants. A pretest, posttest and a 4-month follow-up measurement was conducted. Results revealed improvements in both groups, except for improved reasoning found only in trained participants. These results suggest that: (1) improvements are dependent on the complexity of the program, (2) cognitively stimulating activity are a valid training procedure for old-old, (3) novelty of computer use is an important factor in determining training efficacy.     

Coping Strategies and Resolution in Mothers of Children With Cerebral Palsy

“Parental resolution” represents parents coming to terms with their child’s health condition. Differences in the use of coping strategies between mothers who were resolved versus unresolved to their child’s diagnosis was investigated, and a possible moderating effect of these strategies was explored. A strategy aimed at mobilizing the family to acquire and accept help (institutional, formal support) was shown to be a significant moderating variable, in a way that its more frequent use allowed mothers of children with better functional status (but not mothers of children with poorer functional status) to reach resolution.     

On the automaticity of emotion processing in words and faces: event-related brain potentials evidence from a superficial task

The degree to which emotional aspects of stimuli are processed automatically is controversial. Here, we assessed the automatic elicitation of emotion-related brain potentials (ERPs) to positive, negative, and neutral words and facial expressions in an easy and superficial face-word discrimination task, for which the emotional valence was irrelevant. Both emotional words and facial expressions impacted ERPs already between 50 and 100 ms after stimulus onset, possibly reflecting rapid relevance detection. Following this initial processing stage only emotionality in faces but not in words was associated with an early posterior negativity (EPN). Therefore, when emotion is irrelevant in a task which requires superficial stimulus analysis, automatically enhanced sensory encoding of emotional content appears to occur only for evolutionary prepared emotional stimuli, as reflected in larger EPN amplitudes to faces, but not to symbolic word stimuli.     

It ain’t over ‘til it’s over: The effect of task completion on the savoring of success

The present research investigated a common yet to date unexamined assumption that individuals are unlikely to savor success when they have not yet fully completed a task. In Study 1 (N = 83), we assessed savoring responses of soccer players who were either winning or were tied at the end of the first half (in progress) and at the end of the match (completed). In Study 2 (N = 121 undergraduates), performance feedback (successful vs. average) and task completion (in progress vs. completed) were manipulated and savoring was assessed. In both studies, successful individuals reported savoring their positive experience less when the task was in progress as compared to completed. Results of a third study (N = 152 undergraduates) showed that lower savoring of success was due to individuals’ focus on and worries about future performance as well as the perception that positive emotions have limited utility. We discuss these findings in terms of the consequences for performance and well-being.     

Are children’s memory illusions created differently from those of adults? Evidence from levels-of-processing and divided attention paradigms

In two experiments, we investigated the robustness and automaticity of adults’ and children’s generation of false memories by using a levels-of-processing paradigm (Experiment 1) and a divided attention paradigm (Experiment 2). The first experiment revealed that when information was encoded at a shallow level, true recognition rates decreased for all ages. For false recognition, when information was encoded on a shallow level, we found a different pattern for young children compared with that for older children and adults. False recognition rates were related to the overall amount of correctly remembered information for 7-year-olds, whereas no such association was found for the other age groups. In the second experiment, divided attention decreased true recognition for all ages. In contrast, children’s (7- and 11-year-olds) false recognition rates were again dependent on the overall amount of correctly remembered information, whereas adults’ false recognition was left unaffected. Overall, children’s false recognition rates changed when levels of processing or divided attention was manipulated in comparison with adults. Together, these results suggest that there may be both quantitative and qualitative changes in false memory rates with age.     

Cognitive systems struggling for word order

We argue that the grammatical diversity observed among the world’s languages emerges from the struggle between individual cognitive systems trying to impose their preferred structure on human language. We investigate the cognitive bases of the two most common word orders in the world’s languages: SOV (Subject–Object–Verb) and SVO. Evidence from language change, grammaticalization, stability of order, and theoretical arguments, indicates a syntactic preference for SVO. The reason for the prominence of SOV languages is not as clear. In two gesture-production experiments and one gesture comprehension experiment, we show that SOV emerges as the preferred constituent configuration in participants whose native languages (Italian and Turkish) have different word orders. We propose that improvised communication does not rely on the computational system of grammar. The results of a fourth experiment, where participants comprehended strings of prosodically flat words in their native language, shows that the computational system of grammar prefers the orthogonal Verb–Object orders.     

Rehabilitation Treatments for Adults with Behavioral and Psychosocial Disorders Following Acquired Brain Injury: A Systematic Review

This review was aimed at systematically investigating the treatment efficacy and clinical effectiveness of neurobehavioral rehabilitation programs for adults with acquired brain injury and making evidence-based recommendations for the adoption of these rehabilitation trainings. Using a variety of search procedures, 63 studies were identified and reviewed using a set of questions about research methods, treatments, results and outcomes for the 1,094 participants. The 63 studies included treatments falling into three general categories: approaches based on applied behavior analysis, interventions based on cognitive-behavior therapy (CBT), and comprehensive-holistic rehabilitation programs (CHRPs). Considerable heterogeneity exists in the reviewed literature among treatment methods and within reported sample subjects. Despite the variety of methodological concerns, results indicate that the greatest overall improvement in psychosocial functioning is achieved by CHRP that can be considered a treatment standard for adults with behavioral and psychosocial disorders following acquired brain injury. Both approaches based on applied behavior analysis and CBT can be said to be evidence-based treatment options. However, findings raise questions about the role of uncontrolled factors in determining treatment effects and suggest the need for rigorous inclusion/exclusion criteria, with greater specification of theoretical basis, design, and contents of treatments for both interdisciplinary-comprehensive approaches and single-case methodologies.     

Inter-individual and age differences in exploration, neophobia and problem-solving ability in a Neotropical raptor (Milvago chimango)

Animal innovations have far-reaching ecological and evolutionary consequences. The occurrence and persistence of an innovation require several processes, including exploration, social and asocial learning, and low neophobia. In addition, the identity of the innovator may determine how these new behaviours are socially transmitted. Taking into account inter-individual and age differences, we investigated three correlates of animal innovation: object exploration, neophobia level and novel problem-solving ability in an opportunistic generalist raptor, the Chimango Caracara (Milvago chimango). Eighteen individuals (7 adults and 11 juveniles) were caught during the non-breeding period and housed in individual cages in outdoor aviaries. Each bird was given three tests: exploration, neophobia and problem-solving. Individuals differed in their response to novel situations both within and between age groups. Most of the juveniles were more explorative and had a lower neophobic response to a strange object than adult birds, but both age groups were able to solve a novel problem when given a food reward. In juveniles, neophobia level and problem-solving performance were inversely related; however, we found no relationship between these behaviours in adults. Exploration did not correlate with neophobia or problem-solving ability for either age group. This research is one of the few studies exploring the inter-individual and age differences in behavioural innovation and their correlates in a bird of prey. The explorative tendency, low neophobia and ability to innovate showed by M. chimango may be advantageous for this generalist and opportunistic raptor and might be some of the factors underlying its ecological success.
