Analyzing False Memories in Children with Associative Lists Specific for Their Age.

Two experiments attempted to resolve previous contradictory findings concerning developmental trends in false memories within the Deese-Roediger-McDermott (DRM) paradigm by using an improved methodology--constructing age-appropriate associative lists. The research also extended the DRM paradigm to preschoolers. Experiment 1 (N=320) included children in three age groups (preschoolers of 3-4 years, second-graders of 7-8 years, and preadolescents of 11-12 years) and adults, and Experiment 2 (N=64) examined preschoolers and preadolescents. Age-appropriate lists increased false recall. Although preschoolers had fewer false memories than the other age groups, they showed considerable levels of false recall when tested with age-appropriate materials. Results were discussed in terms of fuzzy-trace, source-monitoring, and activation frameworks.

The Enhanced Cognitive Interview: Towards a Better Use and Understanding of This Procedure:

The Enhanced Cognitive Interview is accepted as one of the most successful techniques for enhancing witness recollection. This type of interview has been studied all over the world (eg, Europe or the USA) and is used by police officers in many different countries (eg, the UK and New Zealand). Nonetheless, it is essential for police officers to understand how, and when, to properly apply this interview. Therefore, we examined the underlying psychological processes involved in this interview, and what research can tells us about the situations and purposes that can benefit from applying it.

Life review with older women: an intervention to reduce depression and improve autobiographical memory

Background and aims: As life expectancy rises worldwide and the population grows older, psychopathology in older adults becomes a significant public health concern and intervention methods acquire renewed importance. The aim of the present study was to assess the efficacy of Life Review as an intervention strategy in working with older women with depressive symptoms, specifically through promotion of the specificity of autobiographical memories. Methods: Twenty-two participants were randomly assigned to experimental or control conditions. Intervention consisted of four individual sessions of Life Review, structured along 14 questions aimed at prompting autobiographical memory specificity. Participants in the control condition did not receive intervention. Results: Results indicated a significant change in the experimental group, appearing as the reduction of depressive symptoms (t(20)=3.58, p<0.05) and an increase in life satisfaction (t(20)=−3.83, p<0.05), as well as a significant increase in the specificity (t(20)=−3.46, p<0.05) and positivity (t(20)=−4.23, p<0.05) of autobiographical memories. All variables reached high effect sizes, with an effect size of r=0.64 regarding depressive symptoms. Conclusions: Results suggest that Life Review is a valuable tool for use with older adults, and that promotion of specific autobiographical memories is a mechanism through which the strategy attains its effectiveness.

Diversidade de resultados no estudo do transtorno de déficit de atenção e hiperatividade

With this paper we aimed at addressing the problem of data diversity in Attention-Deficit Hyperactivity Disorder (ADHD) research. We present a literature review based on the heterogeneity of findings about the characterization of the disorder, subtypes differentiation, sources of information, sex differences and comorbidities. In an effort to understand the variety of findings, we underline potential explanations, such as the samples heterogeneity or the multiplicity of methods and procedures, among others. The review conducted was primarily based on PsycInfo and ERIC databases, but also, on PubMed and Elsevier Direct.

Tactual perception: a review of experimental variables and procedures

This paper reviews the literature on tactual perception. Throughout this review, we will highlight some of the most relevant aspects in the touch literature: type of stimuli; type of participants; type of tactile exploration; and finally, the interaction between touch and other senses. Regarding type of stimuli, we will analyse studies with abstract stimuli such as vibrations, with two- and three-dimensional stimuli, and also concrete stimuli, considering the relation between familiar and unfamiliar stimuli and the haptic perception of faces. Under the “type of participants” topic, we separated studies with blind participants, studies with children and adults, and also performed an overview of sex differences in performance. The type of tactile exploration is explored considering conditions of active and passive touch, the relevance of movement in touch and the relation between haptic exploration and time. Finally, interactions between touch and vision, touch and smell and touch and taste are explored in the last topic. The review ends with an overall conclusion on the state of the art for the tactual perception literature. With this work, we intend to present an organised overview of the main variables in touch experiments, compiling aspects reported in the tactual literature, and attempting to provide both a summary of previous findings, and a guide to the design of future works on tactual perception and memory, through a presentation of implications from previous studies.

Portuguese category norms for children

This study presents Portuguese category norms for children of three different age groups: preschoolers (3- to 4-year-olds), second graders (7- to 8-year-olds), and preadolescents (11- to 12-year-olds). Three hundred Portuguese children (100 in each group) completed an exemplar-generation task. Preschoolers generated exemplars for 13 categories, second graders generated exemplars for 17 categories, and preadolescents generated exemplars for 21 categories. For each group, responses within each category were organized according to frequency of production in order to derive exemplar-production norms for sets of tested categories. The results also included information about the number of responses and exemplars, idiosyncratic and inappropriate responses, and commonality and diversity indexes for all the categories. A comparison of these children’s norms with the Portuguese adult norms was also presented. The full set of norms may be downloaded from www.psychonomic.org/archive.

The enhanced cognitive interview: expressions of uncertainty, motivation and its relation with report accuracy

ABSTRACT The Enhanced Cognitive Interview (ECI) is one of the most widely studied and used methods to interview witnesses. However, ECI research has mainly focused on increasing report size and somewhat overlooked how to improve and evaluate report accuracy. No study evaluated if witnesses’ spontaneous expressions of uncertainty are accurate metacognitive judgments, nor if witnesses’ motivation during the interview affects report accuracy. This study examined how witnesses’ judgments of recall ‘uncertainty’ and their motivation perception could relate to report accuracy. Forty-four psychology students watched a mock robbery video recording and were interviewed 48 hours later with either the Portuguese version of the ECI or a Structured Interview (SI). Afterward, participants’ motivation was assessed and items of information were classified as ‘certainties’ or ‘uncertainties’. Results suggest that our ECI protocol was effective, since participants interviewed with the ECI produced more information without compromising accuracy. ‘Uncertainties’ were less accurate than ‘certainties’, and their exclusion raised overall, ECI, and SI, accuracy. More motivated participants had better recall accuracy. Accounting for witnesses’ motivation and spontaneous verbal expressions of uncertainty may be effective and time-saving procedures to increase accuracy. These are key points that professionals and researchers should consider.

Do Delayed Judgments of Learning Reduce Metamemory Illusions? A Meta-Analysis

Past research has shown that the perceptual characteristics of studied items (e.g., font size) lead to a metamemory illusion, and that delayed judgements of learning (JOLs) are better predictors of memory performance than immediate JOLs. Here, we tested whether delayed JOLs could reduce or eliminate the effect of perceptual characteristics on JOLs and restudy decisions. We adopted a meta-analytic approach and analysed the results of 28 experiments in which participants’ studied items were presented in either large or small font. JOLs and, sometimes, restudy decisions were collected either immediately or after a delay. Finally, participants completed a memory test. The results of the meta-analyses confirmed the effect of the font size on JOLs and restudy decisions. The delayed procedures reliably reduced the effect of perceptual characteristics on JOLs, but the effect was still significant after a delay. For restudy decisions, delayed procedures only reduced numerically the effect. Surprisingly, the meta-analysis also showed a very subtle memory advantage for items presented in large font over small font, although no individual study showed a significant difference and the overall effect size was small. One plausible explanation is that after a delay, information about font size is not available for some items, causing a reduction in the effect. Moreover, our results suggest that the dissociation between memory and metamemory reported previously may not be dissociation at all, but a mistmatched effect of font size on memory and metamemory.

Opposite developmental trends for false recognition of basic and superordinate names

This study investigated the development of false memories for basic and superordinate names using the DRM procedure. Two experiments were conducted with younger (3–5 years old) and older (10–12 years old) children. In the first experiment the DRM procedure was used with categorised lists and in the second experiment both types of lists—categorised and associative—were applied. False recognition for basic and superordinate names showed opposite developmental trends, regardless of list type. False recognition increased for critical-basic items and decreased for critical-superordinate items with age. These opposing results are mainly explained by age differences in conceptual knowledge and editing processes.

Produção de memórias falsas com listas de associados: análise do efeito do nível de processamento e da natureza da prova de memória

Los falsos recuerdos han sido muy estudiados mediante la aplicacion del paradigma DRM (Deese/Roediger/McDermott). El paradigma permite producir ilusiones de memoria tras la presentacion de listas de palabras asociadas a una palabra que no se incluye en la lista. Una de las lineas de investigacion que utilizan el paradigma DRM busca identificar el preciso momento de la creacion de falsos recuerdos y explicar los mecanismos que originan ese efecto. El objetivo de este articulo es hacer una revision de la investigacion sobre el efecto de los niveles de procesamiento y la naturaleza de la tarea de memoria en la facilitacion y inhibicion de la produccion de falsos recuerdos con listas de asociados semanticos.False memories have been widely studied using an experimental procedure called DRM paradigm (Deese/Roediger/McDermott). This paradigm produces memory illusions due to the presentation of lists of words associated to a critical nonpresented word. One line of research on this topic aims at identifying the moment when the false memories are created and the explanation of the mechanisms underling false memories. In this paper we present a review about the effect of level-of-processing and the nature of memory task for the boost or inhibition of false memories created by means of lists of semantic associates.Los falsos recuerdos han sido muy estudiados mediante la aplicacion del paradigma DRM (Deese/Roediger/McDermott).
