The role of associative strength in children's false memory illusions

The effects of associative strength on rates of 7- and 11-year-old children's true and false memories were examined when category and Deese-Roediger-McDermott (DRM) lists were used to cue the same critical lure. Backward associative strength (BAS) was varied such that the category and DRM lists had the same strength (DRM=category), DRM lists had more BAS (DRM>category), or category lists had more BAS (DRM<category). If BAS drives children's false memories then BAS, not the type of relation across items in a list, should determine false memory production. The results confirmed this prediction using both recall and recognition measures: (1) both true and false memories increased with age, (2) true memory was better for category than DRM lists but there were no differences for false memory, and (3) at all ages, false memories varied predictably with changes in BAS but were unaffected by list-type manipulations. These findings are discussed in the context of models of false memory development.     

Understanding the influence of literacy on consumer memory: The role of pictorial elements

This research examines the relationship between literacy and consumer memory. The effects of a variety of stimuli at exposure (i.e., brand names, brand signatures, and products in usage) on memory (i.e., recognition, stem-completion tasks) were examined for a range of literacy. In a series of experiments, we find that the use of pictorial representations of brands (i.e., brand signatures) results in superior brand memory for individuals with lower literacy levels when compared to those at higher literacy levels. This effect is shown to occur not due to pictorial elements per se, but due to pictorial elements with a 1-to-1 correspondence with reality, i.e., which match the form in which they were originally encoded in memory. Moreover, this effect does not persist with stimulus-rich pictures of brands in usage, pointing to boundary conditions with the use of pictorial information.     

Understanding the role of mind wandering in stress-related working memory impairments

Mind wandering has been identified as a possible cause for stress-related working memory (WM) task impairments following laboratory stressors. The current study attempted to induce mind wandering regarding negative, positive, or neutral events using an expressive writing task and examined the impact on WM task performance. We examined the role of mind wandering in understanding the impact of life stress on WM. Additionally, we explored the role of thought suppression on the relationship between mind wandering and WM. One hundred and fifty participants completed WM measures before (Time 1) and after (Time 2) the writing manipulation. The writing manipulation did not alter mind wandering or WM task performance. Time 1 WM predicted mind wandering during the Time 2 WM task, which subsequently predicted poorer Time 2 WM task performance. The impact of daily life stress on WM was mediated by mind wandering. Trait levels of thought suppression moderated the impact of mind wandering on WM. Specifically, higher levels of suppression resulted in stronger negative impact of mind wandering on WM task performance. Findings are discussed in terms of the impact of mind wandering on WM task performance.     

The role of cuing and organization in children's memory for events

Children's memory for a standardized, hierarchically organized event, making clay, was tested in two experiments. Immediately after participating in this event and again 2 weeks later, children described how they had made the clay. In Experiment 1, action and object cues were presented but only action cues greatly facilitated recall. Children who remade the clay reported more information and also reported more of the actions most central to the goal of the event during delayed recall. In Experiment 2, verbal cues representing two levels in the event hierarchy were presented, but neither aided recall. These and other patterns in the data indicated that, at most, the rudiments of a hierarchical structure had emerged after a single experience. These results were discussed in terms of their implications for the development and organization of event memories.     

Understanding children's art: an analysis of the literature

This article attempts to answer the question: "Why is it that an intuitively obvious means of understanding children has not been documented as such?". This is done through a critical analysis of the literature dealing with the validity of the Draw-A-Person Test (DAP). Studies reviewed are analyzed along three parameters; projective test theory, subject population, and psychodiagnostic labeling. On the basis of this analysis, explanations for inconsistencies in the results of the research and suggestions for organizing future work in this area are submitted.     

Experiencing nearby locations together in time: the role of spatiotemporal contiguity in children's memory for location

Three studies investigated how experiencing nearby locations together in time influences memory for location. Seven-, 9-, and 11-year-old children and adults learned 20 object locations in a small-scale space. The space was divided into regions by lines or walls. In Study 1, participants learned the locations either region by region or in a random order. Following learning, participants replaced the objects without the aid of the dots marking the locations and the boundaries subdividing the space. They replaced the objects in any order they chose. After experiencing the locations in random orders during learning, only adults underestimated distances between locations belonging to the same group (i.e., region). Conversely, 9- and 11-year-old children and adults who had experienced the locations region by region during learning underestimated these distances. These findings suggest that experiencing nearby locations together in time increases the weight children assign to categorical information in their estimates of location. Results from Studies 2 and 3 in which participants learned the locations region by region and then replaced the objects region by region (Study 2) or in a random order (Study 3) were similar, highlighting the importance of spatiotemporal cues in memory for location.

Treating another's actions as one's own: children's memory of and learning from joint activity

Children often overestimate their contribution to collaborative activities. Across 2 studies, the authors investigated whether this memory bias supports internalization of the actions of others in the context of joint exchanges. After taking turns with (high collaborative condition; Studies 1 and 2) or working independently of (low collaborative condition; Study 2) an adult experimenter to create a series of novel toys, children's agent memory and reconstruction ability were assessed. Children in the high collaborative condition but not the low collaborative condition systematically overclaimed the actions of their social partner, more frequently reporting having completed steps performed by the experimenter than vice versa. This "I did it" bias was related to learning performance: high collaborative children outperformed low collaborative children both during an immediate reconstruction task and 4 months later, and the strength of the bias predicted children's independent toy-building accuracy. It is argued that the "I did it" bias may emerge as part of a general process of learning from others and is supported by a common framework for representing self-actions and other actions.     

The role of effort type and intensity in children's decisions about effort-based outcomes

Despite the importance of persistence in early learning, we know little about how children reason about outcomes that result from their efforts. Here we examined the role of effort type (i.e., physical vs. cognitive) and intensity (i.e., high vs. low effort) in shaping children's decision making about effort-based rewards. Five- to 7-year-olds (N = 133) were assigned to one of four conditions (High Physical Effort, Low Physical Effort, High Cognitive Effort, Low Cognitive Effort) and completed a series of tasks to construct a toy. Tasks varied in the type (physical/cognitive) and intensity (high/low) of effort required to complete them. After constructing their toy, children completed a series of tasks to probe how much they valued that toy. Across conditions, children preferred their toy and gave it a higher monetary value, relative to a stranger's. However, when choosing their toy came at a cost, children no longer preferred it. Only children who built their toy through either cognitive or low effort were willing to incur a cost for their toy. Older children, across conditions, were also more likely to incur a cost for their toy. These findings demonstrate that by age five, children are sensitive to variations in effort type and intensity, and these factors shape how they evaluate effort-based rewards.     

Understanding bilingual memory: models and data

Bilingual memory research in the past decade and, particularly, in the past five years, has developed a range of sophisticated experimental, neuropsychological and computational techniques that have allowed researchers to begin to answer some of the major long-standing questions of the field. We explore bilingual memory along the lines of the conceptual division of language knowledge and organization, on the one hand, and the mechanisms that operate on that knowledge and organization, on the other. Various interactive-activation and connectionist models of bilingual memory that attempt to incorporate both organizational and operational considerations will serve to bridge these two divisions. Much progress has been made in recent years in bilingual memory research, which also serves to illuminate general (language-independent) memory processes.     

Preschool children's control of action outcomes

Naturalistic goal‐directed behaviours require the engagement and maintenance of appropriate levels of cognitive control over relatively extended intervals of time. In two experiments, we examined preschool children's abilities to maintain top‐down control throughout the course of a sequential task. Both 3‐ and 5‐year‐olds demonstrated good abilities to access goals at the lowest level of the representational hierarchy. However, only 5‐year‐olds consistently aligned their response choices with goals at superordinate levels. These findings suggest that the ability to maintain top‐down control and adjust behavioural responses according to goals at multiple levels of abstraction undergoes a marked improvement throughout the preschool period. Results are discussed in relation to current accounts of cognitive control and the monitoring of conflict in sequential action.     

Peer discussion affects children's memory reports

This study explored the memory conformity effect in children. Younger (6–7 years; n = 60) and older (11–12 years; n = 62) children watched a video individually (individual witness condition) or in dyads (co‐witness condition). The dyads believed that they were viewing the same video as the other member of the pair while in fact the saw different versions. Next, children in the individual witness condition answered questions, whereas children in the co‐witness condition discussed the event on the video with each other. Finally, all children completed an individual free and cued recall task. In the co‐witness condition, more than 60% of the children recalled at least one detail from the alternative video, whereas over 23% of the children in the individual witness condition reported such a detail. Moreover, in free recall—but not in cued recall—the memory conformity effect was stronger for older than for younger children. Copyright © 2007 John Wiley & Sons, Ltd.     

Parenting in youth tennis: Understanding and enhancing children's experiences

ObjectiveThe overall purpose of this study was to develop a grounded theory of optimal parental involvement in youth tennis.DesignA Straussian grounded theory methodology (Corbin and Strauss, 2008, Strauss and Corbin, 1998) was used. Semi-structured interviews and focus groups were conducted with 90 youth tennis players, ex-youth players, parents, and coaches from the United Kingdom. Data were analyzed through a process of open and axial coding, and theoretical integration. Through this process data were broken down into smaller units (concepts), relationships between concepts were identified, and a substantive grounded theory was developed.ResultsThe grounded theory of optimal parental involvement in tennis was built around the core category of ‘understanding and enhancing your child's tennis journey.’ The core category was underpinned by three categories: (a) Share and communicate goals, which referred to the need for parents and children to have the same aims for the child's tennis involvement; (b) develop an understanding emotional climate, which accounted for the need for parents to continually seek to foster an environment in which children perceived parents understand their experience, and; (c) engage in enhancing parenting practices at competitions, which denoted the specific behaviors parents should display in relation to competitive tennis.ConclusionThe theory predicts that consistency between goals, emotional climate, and parenting practices will optimize parenting in youth tennis.
