The development of explicit memory for basic perceptual features

In three experiments with 164 individuals between 4 and 80 years old, we examined age-related changes in explicit memory for three perceptual features--item identity, color, and location. In Experiments 1-2, feature recognition was assessed in an incidental learning, gamelike task resembling the game Concentration. In Experiment 3, feature recognition was assessed using a pencil-and-paper task after intentional learning instructions. The form of the explicit memory function across the life span varied with the particular perceptual feature tested and the type of task. Item recognition was excellent at all ages but was significantly poorer for older adults than children, color recognition peaked in late childhood on the gamelike task, and location recognition peaked in early adulthood on the pencil-and-paper task. These findings indicate that performance on explicit memory tests is not a consistent inverted U-shaped function of age across various features. Explicit memory performance depends on what is measured and how. Because explicit memory typically reflects a composite of different features, age-related changes in explicit memory will not necessarily correspond to the function for any single one.     

The importance of social context in cross-cultural comparisons: first graders in Colombia and the United States

The authors explored the cultural constructs of individualism and collectivism by investigating the prosocial behavior of 1st graders (N = 202; 110 girls, 92 boys) in countries typically classified as collectivist (Colombia, South America) and individualist (United States). Contrary to expectations, U.S. children shared more than Colombian children did. However, U.S. children were more likely to take candy from another child without permission (demonstrating individualism). Results indicated that in both countries sharing was greater with friends than with other fellow classmates, and children frequently reported friendship as the reason they shared. Findings support the importance of the social context, such as the relationship between participants, in cross-cultural research and suggest that simple dichotomies of culture often overlook complex associations between culture and behavioral differences.     

Dissipation of retroactive interference in human infants

In 3 experiments with 85 human 3-month-olds, the authors asked whether retroactive interference with their memory of the original training stimulus is temporary or permanent. Infants learned to move a mobile by kicking and then were exposed to a different mobile (Experiment 1) or context (Experiment 2) immediately or 3 days afterward (Experiment 3). They were tested after increasing delays with the original stimulus, the exposed stimulus, or a completely novel stimulus. Retroactive interference was temporary and unrelated to the exposure delay. The data are consistent with a retrieval-based account of interference. Memory updating (i.e., responding to the interfering stimulus) was coincident with retroactive interference, suggesting that retroactive interference is an adaptive mechanism that facilitates memory updating within a narrow time window.     

Executive functions underlying multiplicative reasoning: Problem type matters

We investigated the extent to which inhibition, updating, shifting, and mental-attentional capacity (M-capacity) contribute to children’s ability to solve multiplication word problems. A total of 155 children in Grades 3–6 (8- to 13-year-olds) completed a set of multiplication word problems at two levels of difficulty: one-step and multiple-step problems. They also received a reading comprehension test and a battery of inhibition, updating, shifting, and M-capacity measures. Structural equation modeling showed that updating mediated the relationship between multiplication performance (controlling for reading comprehension score) and latent attentional factors M-capacity and inhibition. Updating played a more important role in predicting performance on multiple-step problems than did age, whereas age and updating were equally important predictors on one-step problems. Shifting was not a significant predictor in either model. Implications of proposing executive function updating as a mediator between mathematical cognition and chronological age and attention resources are discussed.     

Self-regulated learning in female students with different cognitive styles: an exploratory study

In the present study, the relationship between the cognitive style called field-dependence/independence and learning strategies was explored. Acquisition, encoding, retrieval, support, and meta-cognitive strategies of first-year psychology and social education students (all women; M age = 19.2 yr., SD=1.7) with upper and lower quartile scores on field-dependence/independence were assessed on two self-report questionnaires and compared. Field-dependent students reported greater use of some learning strategies, specifically Self-instructions, Counter-distractions, Self-questioning, Self-monitoring, and Self-evaluation. The possible mediation of cognitive style on the influence of social desirability and a failure to activate appropriate strategies on accuracy of self-reports of learning strategies are discussed. Arguments and data are presented in favour of a distinction among the association of cognitive style with a tendency and capacity to use specific strategies and the benefits and manner of their application.     

Letting Diasporic Voices Be Heard

More than 68.5 million people were forced to move from their countries, according to the UN Refugee Agency, UNHCR, in 2018. Forced displacements are caused by poverty, war, and lack of safety. Since 2015, Europe has been experiencing a so‐called refugee crisis that calls European values and policies into question. Beyond data, there are the experiences of those who are on the move. The number of people arriving on the continent has made integration a decisive topic. This research aims to discover the portrayal of refugees and migrants in media. This goal includes the challenge of making European media evaluate their work to improve the treatment given to complex subjects such as migration. This article is the result of research derived from the project Refugees Reporting in 2017, coordinated by the Europe Region of the World Association for Christian Communistories ancation and the Churches' Commission for Migrants in Europe.     

Irrelevant Information and Mediated Intertemporal Choice

Results from 4 experiments suggest that currencies such as loyalty‐program points are overvalued. Different allocations of the same quantity of points across the same number of purchases (e.g., 100 points for each first, 200 for each second, 300 for each third purchase vs. 200 for each first, second, and third purchase) yielded irrelevant trends and should have led participants to ignore loyalty points as a basis for choice. However, choices were influenced by points even when consumers were provided with other truly discriminating information (e.g., price) and the irrelevance of the loyalty points was readily discernable. This implies that irrelevant information can influence choice when other, easily justifiable bases for decisions are available and, therefore, that irrelevant information can function as more than a tie‐breaker. Other implications for research on irrelevant attributes, medium effects, intertemporal choice, and loyalty programs are discussed.     

Instruction Modes for Motor Control Skills Acquisition: A Randomized Controlled Trial

Abstract

The objective was to compare two different instruction modes used to teach patients with nonspecific chronic low back pain (CLBP) to perform a lumbar motor control task. The three intervention instruction modes used were: common verbal explanation of a motor task based on a motor control therapeutic exercise (MCTE-control group), MTCE instructed using motor imagery (MI) and MCTE instructed using tactile feedback (TF). The main outcome measure was lumbar motor control of the neutral position test. Forty-eight patients with CLBP were randomly allocated into three groups of 16 patients per group. The MI strategy was the most effective mode for developing the motor control task in an accurate and controlled manner, obtaining better outcomes than TF or verbal instruction.     

A matching-to-sample feedback technique for training self-control of tinnitus

Thirty individuals with subjective tinnitus aurium of a variety of types and severity were treated with a matching-to-sample feedback procedure. Following initial evaluation measures, the participants' experienced tinnitus sounds were reproduced audiometrically on all characteristics and were presented to them in the noninvolved ear or in both ears when the tinnitus was binaural. This experimental sound was then reduced in 5 decibel (dB) steps within sessions, and participants had the task of concentrating on reducing the loudness of their tinnitus until a match was achieved between it and the experimental sound at each new dB level. Results showed an overall highly significant difference in dB levels from baseline to final training session. Nearly all participants demonstrated a marked reduction in tinnitus loudness, with 84% reducing it by 10 dB to 62 dB and several eliminating it completely. Individual and pathological variables played no role in training or outcome. Our approach appears to have major advantages over other tinnitus treatment strategies in that it provides direct, significant relief and gives the patient the psychological benefit of gaining control over the problem.
