Combining verbal veracity assessment techniques to distinguish truth tellers from lie tellers / Combinando técnicas verbales de evaluación de la veracidad para discriminar testimonios verdaderos de falsos

Cognitive Credibility Assessment (CCA) is a verbal lie detection tool consisting of several interview techniques. These techniques have been examined separately but never together. Reflecting the dynamic nature of CCA we combined several of the techniques (free recall followed by a model statement, followed by a reverse order instruction, and followed by a sketch instruction). We examined the new information provided after each stage of the interview and also compared the information provided in the initial recall with the information provided after the entire interview. A total of 47 truth tellers and 47 lie tellers went on a mission. Truth tellers were asked to report their mission truthfully, whereas lie tellers were requested to lie about several aspects of the mission. We measured the total units of information (total details) provided in the interview and the number of complications reported. The results indicate that the pre-registered hypothesis (Hypothesis 1) was supported for complications. Truth tellers reported more complications than lie tellers in each stage of the interview and the difference was more pronounced after the entire interview than after the free recall. As a conclusion, CCA was an effective lie detection method when complications were taken into account

La evaluación cognitiva de la credibilidad (ECC) es una herramienta verbal de detección de mentiras que incluye varias técnicas de entrevista. Dichas técnicas se han examinado por separado pero nunca juntas. Para reflejar el carácter dinámico de la ECC combinamos varias de las técnicas (recuerdo libre seguido de una declaración tipo, seguido de una instrucción de recuerdo en orden inverso, y de una instrucción para que hagan un sketch -esquema- durante la narración del evento). Analizamos la información nueva proporcionada tras cada etapa de la entrevista y también comparamos la información procedente del recuerdo inicial con la aportada por toda la entrevista. Un total de 47 sujetos que decían la verdad y 47 que mentían fueron enviados a una misión. A los participantes de la condición de testimonio verdadero se les pidió que informaran de su misión de modo veraz, mientras que los de la condición de mentira se les solicitó que mintieran sobre distintos aspectos de la misión. Se midió el total de unidades de información (detalles totales) de la entrevista y el número de complicaciones de las que se informaba. Los resultados mostraron que los participantes de la condición de verdad informaban de más detalles y complicaciones (hipótesis 1) en cada fase de la entrevista siendo las mayores diferencias tras la entrevista global que tras el recuerdo libre. En conclusión, la categoría complicaciones de la ECC es eficaz en la detección de la mentira

Varieties of graded forgetting.

Forgetting is typically viewed as counterproductive in everyday life. However, it may mainly be harmful when it is complete, that is, all-encompassing and permanent, and not when it is graded, that is, partial and fluctuating. I propose that forgetting is in fact mostly graded, and that this is an essential reason that it is often helpful. I delineate three ways in which forgetting may be graded. First, it may occur with respect to one, but not another, part of a memory. Second, it may occur in one context, but not in another. Third, forgetting may be present at one point in time, but not at another. Also, I propose that different levels of forgetting are possible, based on whether an engram or a context is unavailable, silent, restricted, latent, or potent. Overall, I hypothesize that forgetting is often helpful because it can be flexible and tailored to the circumstances.

Sub-types of nonbelieved memories reveal differential outcomes of challenges to memories.

Nonbelieved memories (NBMs) highlight the independence between distinct metamemorial judgements that contribute to the experience of remembering. Initial definitions of NBMs portrayed them as involving the withdrawal of belief in occurrence despite sustained recollection. While people rate belief for their NBMs as weaker than recollection, the average difference is too small to support the idea that autobiographical belief is completely withdrawn in all cases. Furthermore, autobiographical belief and recollection ratings vary considerably across NBMs. In two studies, we reanalysed data from prior studies to examine whether NBM reports reflect a single category or multiple sub-categories using cluster analytic methods. In Study 1, we identified three sub-types of NBMs. In Study 2 we incorporated the concept of belief in accuracy, and found that two of the clusters from Study 1 split into two clusters apiece. All clusters were characterised by higher recollection than belief in occurrence ratings, and clusters were differentiated by the degree of difference between these variables. In both studies the clusters were discriminated by a number of memory characteristic ratings and by reasons reported as leading to the alteration of belief. Implications for understanding the remembering of past events and predicting the creation of NBMs are discussed.

Is there a deficit in recognition in old age? / ¿El reconocimiento empeora al envejecer?

BACKGROUND: There is some debate over of the effect of aging on the ability to recognize previously processed information. The aim of the present study is to analyze, by means of different measurements, whether aging has differential effects on recall and recognition of visual and verbal materials. METHOD: A within-subject design was used to compare two groups of different age (younger, older) in tasks of recall and recognition of images and of the verbal descriptors exchanged in a conversation. RESULTS: The results indicated that, unlike the recall and recognition of words, better in younger participants, the recall and recognition of images was equal in both groups, or even better in older participants when assessed by means of d'. Nevertheless, a more strict recently proposed measurement, the conditional probability for recall given recognition, yielded significant age differences in all instances. Besides, the conditional probability shows the aging changes usually found in the serial position curve: decline of the primacy effect, while maintenance of the recency effect. CONCLUSIONS: Results are explained according to the theories that postulate two components in the process of recognition (familiarity and recollection), which are independently affected by aging

ANTECEDENTES: existe controversia acerca del efecto del envejecimiento sobre la habilidad para reconocer información previamente procesada. El principal objetivo del estudio es analizar, mediante distintas medidas, si al envejecer se produce un declive diferencial del recuerdo y el reconocimiento de materiales visuales y verbales. MÉTODO: se comparó con un diseño intrasujetos el rendimiento de dos grupos de distinta edad (joven, mayor) en tareas de recuerdo y reconocimiento de imágenes y de los descriptores verbales intercambiados en una conversación. RESULTADOS: los resultados indicaron que, a diferencia del recuerdo y reconocimiento de palabras, mejor en jóvenes, el recuerdo y reconocimiento de imágenes es igual en ambos grupos, o incluso mejor en los mayores mediante estimaciones como d'. Sin embargo, una medida más estricta recientemente propuesta, la probabilidad condicionada de recordar la información reconocida, muestra diferencias significativas en función de la edad en todos los casos. Además, dibuja el cambio habitual de la curva de posición serial al envejecer: declive del efecto de primacía y mantenimiento del efecto de recencia. CONCLUSIONES: los resultados se explican en el marco de las teorías que postulan dos componentes en el proceso de reconocimiento (familiaridad y recuperación), sobre los que el envejecimiento tiene distintos efectos

Reasons for withdrawing belief in vivid autobiographical memories.

Previous studies have shown that many people hold personal memories for events that they no longer believe occurred. This study examines the reasons that people provide for choosing to reduce autobiographical belief in vividly recollected autobiographical memories. A body of non-believed memories provided by 374 individuals was reviewed to develop a qualitatively derived categorisation system. The final scheme consisted of 8 major categories (in descending order of mention): social feedback, event plausibility, alternative attributions, general memory beliefs, internal event features, consistency with external evidence, views of self/others, personal motivation and numerous sub-categories. Independent raters coded the reports and judged the primary reason that each person provided for withdrawing belief. The nature of each category, frequency of category endorsement, category overlap and phenomenological ratings are presented, following which links to related literature and implications are discussed. This study documents that a wide variety of recollective and non-recollective sources of information influence decision-making about the occurrence of autobiographical events.

The classification of recovered memories: a cautionary note.

Traditionally, recovered memories of childhood sexual abuse (CSA) have been classified as those emerging spontaneously versus those surfacing during the course of suggestive therapy. There are indications that reinterpretation of memories might be a third route to recovered memories. Thus, recovered memories do not form a homogeneous category. Nevertheless, the conceptual distinctions between the various types of recovered memories remain difficult for researchers and clinicians. With this in mind, the current study explored whether recovered memories can be reliably classified. We found that classification is rather problematic in a subset of cases. To reduce potential bias, we urge for the development and subsequent use of a more reliable classification system and multiple expert raters in research on recovered memories.

Evaluación de la información suministrada por el médico especialista sobre la enfermedad de Alzheimer y de la retención lograda por los cuidadores del enfermo / Assessment of the information provided by the medical specialist on Alzheimer's disease and that retained by the patient caregivers

Existen evidencias de la insuficiente capacidad informativa por parte de los especialistas médicos, así como de las dificultades retentivas de los pacientes con enfermedad de Alzheimer (EA) y de sus cuidadores. Entre las diversas causas figuran tanto las limitaciones personales del profesional como los determinantes externos, emocionales y socioculturales del paciente y de su cuidador. Contrastar la información clínica proporcionada por los médicos sobre la EA y la percibida por los cuidadores y evaluar los factores asociados a las diferencias de percepción. Pacientes y métodosSe llevó a cabo un estudio observacional, multicéntrico y nacional mediante cuestionarios que evalúan la información suministrada por el médico y la retenida por el paciente en 17 aspectos informativos. Participaron 61 investigadores que incluyeron a un total de 679 pacientes que cumplían los criterios de selección. Se evaluaron los factores asociados a la diferencia de percepción sobre la información transmitida.Resultados: Los cuidadores participantes tenían una media de 57,2±14,8 años, habiendo dedicado un tiempo medio como cuidadores de 27,6±28,0 meses, y siendo el 50,9% hijos del paciente que mayoritariamente vivían en el mismo domicilio (64,9%). Los cuidadores valoraron significativamente mejor la información recibida sobre: concepto de la enfermedad, aspectos etiopatogénicos, posología y recomendaciones sobre el tratamiento y adherencia terapéutica, mientras que los médicos consideraron significativamente mejor la información referente a desmitificación y corrección de concepciones previas, posibles complicaciones, riesgos, efectos adversos y/o yatrogenia, asociaciones de familiares, y ayuda emocional/psicológica a cuidadores (p<0,05). La concordancia en la información suministrada y la recibida fue entre pobre y débil (Kappa ≤ 0,27). El grado de evolución de la enfermedad (escala GDS) fue un factor significativamente asociado con la discordancia profesional-cuidador (p=0,002) (AU)

Introduction: There is evidence of insufficient communication abilities by medical specialists as well as of the limited retentive capacities of patients with Alzheimer disease (AD) and their caregivers. The main reasons for this include the personal limitations of the physician, as well as external, emotional and social-cultural factors associated with the patients and their caregivers. The aim of this study is to compare the clinical information on AD provided by the physicians and that perceived by caregivers and to assess factors associated with differences in perception. Patients and methods: We carried out an observational national multicentre study based on questionnaires assessing the information provided by the physician and that retained by the caregiver for 17 items of information. The study involved 61 researchers and included a total of 679 patients who met the selection criteria. We evaluated the factors associated with the difference in perception of the information that was transmitted. Results: Participating caregivers had a mean age of 57.2±14.8 years, with an average care time of 27.6±28.0 months. Approximately half (50.9%) were children of the AD patient and most lived in the same household (64.9%). Caregivers assigned significantly higher ratings to information on concept of disease, aetiology, pathogenesis, dosage and treatment recommendations and adherence, while doctors assigned significantly higher ratings to information related to demystification and correcting preconceived notions, possible complications, adverse events and/or iatrogenesis, family associations, and emotional/ psychological support to caregivers (P<.05). Concordance between the information provided and that received was classified between poor and weak (inter-rater agreement ≤ 0.27). The degree of disease progression using the Global Deterioration Scale (GDS) was a factor significantly associated with professional-carer information discrepancy (P=.002) (AU)

Classifying retrieval strategies as a function of working memory.

Strategy selection may help explain performance differences between individuals with high working memory capacity (HWMs) and low working memory capacity (LWMs) (Budd, Whitney, & Turley, (Memory & Cognition, 23, 735-748 1995); Cokely, Kelley, & Gilchrist, (Psychonomic Bulletin & Review, 13, 991-997 2006). We compared the independent and spontaneous strategy use of HWMs and LWMs during a category fluency (retrieval) task that required participants to retrieve animal names. HWMs were more successful at the fluency task under normal conditions, but under increased cognitive load, there were no WM-related performance differences. One strategy (i.e., retrieving animals according to their scientific classification) significantly aided performance, irrespective of cognitive load. Under normal conditions, HWMs were more likely to use the effective strategy; however, under load, WM did not predict strategy use. Use of the classification strategy was more strongly related to retrieval performance than was WM. These results suggest that retrieval strategy use is related to WM capacity, and that employing a successful strategy may make up for WM disadvantages during a demanding retrieval task.

The origin of the interaction between learning method and delay in the testing effect: the roles of processing and conceptual retrieval organization.

Recent research has demonstrated a relationship between retrieval organization and the efficacy of prior repeated retrieval on delayed tests. The present study asked why repeated study engenders higher recall at a short delay despite lower retrieval organization but produces a decline at a long delay, and why repeated retrieval engenders lower recall at a short delay despite higher retrieval organization but produces stable recall over time. This relationship was examined through the inclusion of two successive recall tests-one immediately after learning method and one a week later. Results replicated the interaction in recall between learning method and delay characterizing the testing effect and, critically, revealed the qualitative differences inherent in the retrieval organization of each method. Specifically, stable recall in repeated retrieval was accompanied by strong and sustained conceptual organization, whereas organization for repeated study was tenuous and weakened across tests. These differences quantitatively were assessed through the use of five targeted analyses: specifically, the examination of cumulative recall curves, the accumulation of organization across time (a curve akin to cumulative recall), item gains and losses across time, changes in the size of categories across time, and the fate of specific clusters of recalled items across time. These differences are discussed within the context of differential processes occurring during learning method.

Tooth loss, apolipoprotein E, and decline in delayed word recall.

Our previous research suggests an association between a low number of teeth and increased risk of dementia. The aim of the present study was to determine if a low number of teeth is specifically related to memory decline as evidenced by low Delayed Word Recall scores. In addition, we examined the combined effect of a low number of teeth and the apolipoprotein E epsilon4 allele on Delayed Word Recall scores. We hypothesized that the scores of those who had the allele and a low number of teeth (0-9) would decline more rapidly over time than those participants with a greater number of teeth who lacked the allele. We found that individuals with both risk factors (the allele and fewer teeth) had lower Delayed Word Recall scores at the first examination and declined more quickly compared with participants with neither of these risk factors or with either risk factor alone.

Compensatory rationalizations and the resolution of everyday undeserved outcomes.

People prefer to perceive the world as just; however, the everyday experience of undeserved events challenges this perception.The authors suggest that one way people rationalize these daily experiences of unfairness is by means of a compensatory bias. People make undeserved events more palatable by endorsing the notion that outcomes naturally balance out in the end--good, yet undeserved, outcomes will balance out bad outcomes, and bad undeserved outcomes will balance out good outcomes.The authors propose that compensatory biases manifest in people's interpretive processes (Study 1) and memory (Study 2). Furthermore, they provide evidence that people have a natural tendency to anticipate compensatory outcomes in the future, which, ironically, might lead them to perceive a current situation as relatively more fair (Study 3).These studies highlight an understudied means of justifying unfairness and elucidate the justice motive's power to affect people's construal of their social world.

Temporal distribution of favourite books, movies, and records: differential encoding and re-sampling.

The reminiscence bump is the effect that people recall more personal events from early adulthood than from childhood or adulthood. The bump has been examined extensively. However, the question of whether the bump is caused by differential encoding or re-sampling is still unanswered. To examine this issue, participants were asked to name their three favourite books, movies, and records. Furthermore,they were asked when they first encountered them. We compared the temporal distributions and found that they all showed recency effects and reminiscence bumps. The distribution of favourite books had the largest recency effect and the distribution of favourite records had the largest reminiscence bump. We can explain these results by the difference in rehearsal. Books are read two or three times, movies are watched more frequently, whereas records are listened to numerous times. The results suggest that differential encoding initially causes the reminiscence bump and that re-sampling increases the bump further.

Reminiscence and vivid personal memories across adulthood.

This study examined reminiscence functions and vivid (i.e., landmark) personal memories in nine samples ranging from the teens to the nineties. Participants (n = 198) ranging in age from 18-95 years completed the Reminiscence Functions Scale (Webster, 1997) and described a vivid personal memory which was subsequently rated for frequency of recall, emotional valence, time of occurrence, impact, and thematic content. Reminiscence results showed that older adults tend to reminiscence more for social functions while younger adults tend to reminisce more for self functions. Older adults reported vivid memories that were less intimate and less negative although adults of all ages showed the "reminiscence bump." Significant relationships were also obtained between the content of vivid memories described and the patterns of general reminiscence behaviors.

Investigación sobre fluctuaciones de la memoria en pares asociados / A research about paired associated fluctuations memory

Se exploraron por vez primera las fluctuaciones de la memoria así como reminiscencia e hipermnesia – dos formas de recuperación de la memoria – utilizando un paradigma de pares asociados (PAS). Quince PAS fueron presentados sin instrucciones específicas de codificación, probándose su recuerdo en dos ensayos. Los principales resultados indican: (1) El nivel de fluctuaciones entre ensayos fue exiguo. (2) No hubo vestigio de hipermnesia. A pesar de los resultados anteriores, (3) se produjo reminiscencia altamente significativa. Estos resultados se interpretan en función de la hipótesis de vías alternativas de recuperación (ARP; Kazén y Solís-Macías, 1999; Solís-Macías, 1998). ARP predice que la hipermnesia emerge por la activación de rutas alternativas que transforman en accesible información que hasta entonces sólo se encontraba disponible en la memoria. Los PAS limitaron rígidamente el acceso a vías alternativas, por lo que no se generó el fenómeno hipermnésico, pero sí la reminiscencia. Finalmente, se obtuvo evidencia de condiciones limítrofes para la generación de hipermnesia

The phenomena of memory fluctuations plus two incremental memory effects, hypermnesia and reminiscence were explored for the first time using a paired associates (PAS) paradigm. Fifteen PAS were presented without specific encoding instructions; their recall was tested twice. The main results show: (1) Insignificant levels of between trial fluctuations. (2) No sign of hypermnesia. (3) In spite of the previous results, however, highly significant reminiscence. These results are interpreted in terms of the alternative retrieval pathways hypothesis (ARP; Kazén y Solís-Macías, 1999; Solís-Macías, 1998). ARP suggests that hypermnesia emerges due to the activation of such alternative retrieval pathways; that activation transforms a proportion of the available information registered in memory into an accessible form. Using PAS rigidly limited access to alternative retrieval pathways, hence hypermnesia was not observed although reminiscence did occur. These results reveal some boundary conditions for generating hypermnesia

The effect of intellectual disability on children's recall of an event across different question types.

This research examined the performance of 80 children aged 9-12 years with either a mild and moderate intellectual disability when recalling an innocuous event that was staged in their school. The children actively participated in a 30-min magic show, which included 21 specific target items. The first interview (held 3 days after the magic show) provided false and true biasing information about these 21 items. The second interview (held the following day) was designed to elicit the children's recall of the target details using the least number of specific prompts possible. The children's performance was compared with that of 2 control groups; a group of mainstream children matched for mental age and a group of mainstream children matched for chronological age. Overall, this study showed that children with either a mild or moderate intellectual disability can provide accurate and highly specific event-related information. However, their recall is less complete and less clear in response to free-narrative prompts and less accurate in response to specific questions when compared to both the mainstream age-matched groups. The implications of the findings for legal professionals and researchers are discussed.

[Questions about questions: cognitive survey of questionnaire development]. / Fragen über Fragen: cognitive survey in der Fragebogenentwicklung.

OBJECTIVES: Traditional pretests are used in the development of survey items to identify technical and comprehension problems. Cognitive processes involved in answering survey questions are not the object of this kind of test. METHODS: Cognitive survey methods were used here to test a questionnaire screening for rehabilitation needs in people suffering from back pain. Essential techniques of cognitive testing (think-aloud, probing, confidence ratings) are outlined. We applied these techniques to 20 patients suffering from either acute or chronic back pain in order to test the survey. RESULTS: The main goal, i.e., identifying problems in item formulation by means of cognitive testing, was achieved. Almost one third of the survey questions were rephrased according to the results of the study. Some of the improvements of the questionnaire are illustrated. CONCLUSIONS: The increased effort required to perform cognitive testing as compared to traditional pretesting pays off. The two methods have specific pros and cons and cannot replace one another.

Reverse versus forward order reporting and the accuracy of fourth-graders' recalls of school breakfast and school lunch.

BACKGROUND: Do children recall school breakfast and school lunch intake during 24-h recalls more accurately when prompted to report meals and snacks in reverse versus forward order? METHODS: One hundred twenty-one fourth-graders stratified by race (Black, White) and gender were each observed and interviewed twice (once per order) regarding the previous day's intake. Omission and intrusion rates determined accuracy for reporting items. Total inaccuracy determined accuracy for reporting items and amounts. RESULTS: Results failed to indicate significant effects of interviewer, weekday, sequence (first or second recall), or race on omission rates, intrusion rates, or total inaccuracy. A significant order by gender interaction was found for omission rates, which were lower (i.e., better) for males for reverse (53%) versus forward recalls (62%), but not females (61 versus 53%) (P < 0.008). Intrusion rates were acceptable for males for 54% of reverse recalls and 40% of forward recalls (P = 0.095). Means were 57 and 32%, and 6.4 servings for omission rate, intrusion rate, and total inaccuracy for reverse recalls, and 56 and 39%, and 6.9 servings for forward recalls. CONCLUSIONS: Prompting children to report in reverse versus forward order improved omission and intrusion rates for males more so than females. Regardless of reverse or forward order, children reported <50% of items observed; furthermore, >30% of items reported were not observed. Research is needed to enhance accuracy of children's dietary recalls.

Información categórica y de orden en el recuerdo libre de frases de acciones / Categorical and order information in free recall of action phrases

Partiendo del modelo de recuerdo libre "generación-reconocimiento", abordamos dos puntos. En primer lugar discutiremos si el efecto de "actuación", es decir, el recuerdo superior de acciones que uno mismo ha realizado (AUR) sobre las acciones realizadas por otros (ARO) o sobre las tareas verbales (TV) se debe al fortalecimiento de la información relacional y/o de item en las condiciones de AUR. En segundo lugar, proponemos que es necesario distinguir entre, al menos, dos tipos de información relacional: categórica y episódica (de orden). Mostraremos a) que la información categórica se utiliza por igual en AUR, ARO y TV, b) que la información episódica relacional es más eficaz en la condición ARO pura que en la AUR. c) que esta ventaja se pierde cuando las dos condiciones de codificación se mezclan y d) que la información episódica relacional se puede utilizar de forma efectiva con listas cortas , pero no con listas largas. Esta variabilidad de la información episódica relacional determina que la condición AUR produzca mejor recuerdo que la ARO (AU)

The role of taxonomies in the study of human memory.

The idea that memory is not unitary but is instead composed of multiple systems has a long history and has been debated with particular vigor in the last 20 years. Nevertheless, whether or not there are multiple memory systems remains unsettled. In this article, we suggest that psychologists wishing to classify memory can learn from biological systematics, the discipline that creates taxonomies of species. In so doing, we suggest that psychologists have made two assumptions in classifying memory: that features of memory are perfectly correlated, and that there is a straightforward mapping between taxonomy and theory. We argue that these assumptions are likely to be incorrect, but we also argue that there is a place for taxonomy in the study of memory. Taxonomies of memory are organizational schemes for data--they are descriptive, not explanatory--and so can inspire theory, although they cannot serve as theories themselves.

Efectos del olvido dirigido con el método de las palabras: una comparación entre pruebas directas e indirectas de memoria / Effects of directed forgetting with the word method: comparison between direct and indirect memory test

En el presente estudio se analizaron los efectos del olvido dirigido en pruebas directas (reconocimiento y recuerdo) e indirectas (categorización y detección de letras). Los resultados mostraron que las palabras marcadas para aprender se recordaban mejor y se reconocían más rápido y con mayor precisión que las marcadas para olvidar. Este patrón de resultados se replicó con la prueba de categorización. Sin embargo, no se encontró olvido dirigido en la prueba de detección de letras. Los resultados se discuten en función de la hipótesis basada en el repaso diferencial como mecanismo implicado en el olvido dirigido con el método de las palabras (AU)
