Are self reports of memory failure accurate?

Previous research with memory questionnaires has been interpreted as showing that people do not recall their memory failures accurately. The present research consisted of three investigations that examined whether participants' reports of memory failures were corroborated by their spouses. These investigations used a greater variety of statistical and survey methods than were used in previous investigations. The results demonstrated that people are able to recall memory failures more accurately than previous research indicated. These results have important methodological and theoretical implications for basic and applied assumptions about what people know about their memory failures.

The rubber hand illusion in a mirror

In the rubber hand illusion (RHI) one’s hand is hidden, and a fake hand is visible. We explored the situation in which visual information was available indirectly in a mirror. In the mirror condition, compared to the standard condition (fake hand visible directly), we found no reduction of the RHI following synchronised stimulation, as measured by crossmanual pointing and by a questionnaire. We replicated the finding with a smaller mirror that prevented visibility of the face. The RHI was eliminated when a wooden block replaced the fake hand, or when the hand belonged to another person or mannequin. We conclude that awareness of the reflection is the critical variable, despite the distant visual localisation of the hand in a mirror and the third-person perspective. Stimuli seen in a mirror activate the same response as stimuli seen in peripersonal space, through knowledge that they are near one’s body.     

Using confirmatory factor analysis to understand executive control in preschool children: sources of variation in emergent mathematic achievement

Latent variable modeling methods have demonstrated utility for understanding the structure of executive control (EC) across development. These methods are utilized to better characterize the relation between EC and mathematics achievement in the preschool period, and to understand contributing sources of individual variation. Using the sample and battery of laboratory tasks described in Wiebe, Espy and Charak (2008), latent EC was related strongly to emergent mathematics achievement in preschool, and was robust after controlling for crystallized intellectual skills. The relation between crystallized skills and emergent mathematics differed between girls and boys, although the predictive association between EC and mathematics did not. Two dimensions of the child ’s social environment contributed to mathematics achievement: social network support through its relation to EC and environmental stressors through its relation with crystallized skills. These findings underscore the need to examine the dimensions, mechanisms, and individual pathways that influence the development of early competence in basic cognitive processes that underpin early academic achievement.     

Thalamic pathways for active vision

Active vision requires the integration of information coming from the retina with that generated internally within the brain, especially by saccadic eye movements. Just as visual information reaches cortex via the lateral geniculate nucleus of the thalamus, this internal information reaches the cerebral cortex through other higher-order nuclei of the thalamus. This review summarizes recent work on four of these thalamic nuclei. The first two pathways convey internal information about upcoming saccades (a corollary discharge) and probably contribute to the neuronal mechanisms that underlie stable visual perception. The second two pathways might contribute to the neuronal mechanisms underlying visual spatial attention in cortex and in the thalamus itself.     

Inside Criminal Minds: Offenders' Strategies when Lying

This study aimed at extending the deception literature by examining lie‐telling strategies given by persons with criminal experience. In interviews taking place in prisons, offenders (n = 35) provided lie‐telling strategies in a free narrative style. In an inductive content analysis, we coded both all strategies provided as well as one principal strategy for each participant. In total, 13 strategies were identified, which were grouped into three broader category groups: general verbal, general nonverbal, and specific interview strategies. The most often stated strategies were Close to truth, Eye contact, and No strategy. The most often stated principal strategies were Close to truth, Not giving away information, and No strategy. Some participants provided strategies, such as not giving away information at all in interviews/interrogations, which showed a sophisticated understanding of the police interview situation and the task of the police and prosecutor. Overall, the participants showed great diversity in preferred lie‐telling strategy. The results are partly in line with previous research from student samples and provide new insights into the criminally experienced individuals' lie‐telling strategies. The results are discussed with regard to impression and information management and police interrogation practice. Copyright © 2011 John Wiley & Sons, Ltd.     

How Effective is the Enhanced Cognitive Interview when Aiding Recall Retrieval of Older Adults including Memory for Conversation?

The percentage of older adults in the general population is growing. As a result, older adults are coming more frequently into contact with the Criminal Justice System as witnesses to and victims of crime. Older adults are also over‐represented in crimes where conversation detail is of particular importance to an investigation (e.g. distraction burglary). The present study therefore examined the efficacy of cognitive interview (CI) compared with structured interview in improving the recall of an event by older witnesses, specifically conversational detail. Young adults (19–54 years old), young‐old adults (60–74 years old), and old‐old adults (75+ years old) were asked to watch a short film of a laptop theft and were then, after a 1.5 hour delay, randomly allocated to one of two interview conditions. It was found that the CI significantly increased recall of all age groups, without increasing the amount of incorrect or confabulated information reported. The individuals in the young adult and the young‐old adult conditions were found to remember significantly more than the individuals from the old‐old adult condition, without decreasing the accuracy of the information. The CI enhanced memory for conversation gist, person and action detail. Results will be discussed in relation to interviewing and investigating practices.

Depression and anxious apprehension distinguish frontocingulate cortical activity during top-down attentional control

A network consisting of left dorsolateral prefrontal cortex (LDLPFC) and dorsal anterior cingulate cortex (dACC) has been implicated in top-down attentional control. Few studies have systematically investigated how this network is altered in psychopathology, despite evidence that depression and anxiety are associated with attentional control impairments. Functional MRI and dense-array event-related brain potential (ERP) data were collected in separate sessions from 100 participants during a color-word Stroop task. Functional MRI results guided ERP source modeling to characterize the time course of activity in LDLPFC (300-440 ms) and dACC (520-680 ms). At low levels of depression, LDLPFC activity was indirectly related to Stroop interference and only via dACC activity. In contrast, at high levels of depression, dACC did not play an intervening role, and increased LDLPFC activity was directly related to decreased Stroop interference. Specific to high levels of anxious apprehension, higher dACC activity was related to more Stroop interference. Results indicate that depression and anxious apprehension modulate temporally and functionally distinct aspects of the frontocingulate network involved in top-down attention control.     

Validity of the PAI interpersonal scales for measuring the dimensions of the interpersonal circumplex

Two studies evaluated the validity of the interpersonal scales, Dominance (DOM) and Warmth (WRM), from the Personality Assessment Inventory (PAI; Morey, 1991, 2007) to measure the 2 dimensions of the interpersonal circumplex (IPC). In Study 1, 114 college freshmen completed the PAI and the Interpersonal Adjectives Scale (IAS; Wiggins, 1995). In Study 2, 170 college students completed the PAI and the Inventory of Interpersonal Problems-Short Circumplex (IIP-SC; Soldz, Budman, Demby, & Merry, 1995). The results of both studies supported the convergent validity of DOM and WRM, although discriminant validity was stronger using the IIP-SC as the criterion. Circumplex projections placed DOM and WRM in the appropriate segments of both the IAS and IIP-SC. These findings provide additional support for the validity of the PAI interpersonal scales as measures of the primary dimensions of the IPC.     

Early differentiation between drawing and writing in Chinese children

Children under 3½ years of age or so are often thought to produce the same types of scribbles for writing and drawing. We tested this idea by asking Chinese 2- to 6-year-olds to write and draw four targets. In Study 1, Chinese adults judged the status of the productions as writings or drawings. The adults performed significantly above the level expected by chance even with the productions of 2- to 2½-year-olds. In Study 2, we examined specific characteristics of the children’s writings and drawings. Although the younger children’s scribbles bore little resemblance to the correct characters, they tended to be smaller, sparser, and more angular than their artwork, with less filling in. Differences were also found in paper use and implement use. Children did not appear to distinguish writing from drawing for their own names before they did so for other targets.     

Strategies and attributes of highly productive scholars and contributors to the school psychology literature: recommendations for increasing scholarly productivity

In all academic fields, there are scholars who contribute to the research literature at exceptionally high levels. The goal of the current study was to discover what school psychology researchers with remarkably high levels of journal publication do to be so productive. In Study 1, 94 highly productive school psychology scholars were identified from past research, and 51 (39 men, 12 women) submitted individual, short-answer responses to a 5-item questionnaire regarding their research strategies. A constant comparative approach was employed to sort and code individual sentiments (N=479) into categories. Seven broad categories of counsel for increasing productivity emerged: (a) research and publication practices and strategies, (b) collaboration, mentoring and building relationships, (c) navigating the peer-review process, (d) strategies to bolster writing productivity and excellence, (e) personal character traits that foster productivity, (f) preparation before entering the professoriate, and (g) other noteworthy sentiments. Results are discussed in terms of nine recommendations for scholars and graduate students who wish to increase their productivity. In Study 2, five of the most productive scholars (1 woman, 4 men) participated in a semi-structured interview about their high levels of productivity. Interviews were recorded, transcribed, and analyzed, and a case analysis approach employed to profile each scholar. Study limitations and suggestions for future research are discussed.
