Investigating the Awareness of Remembering

ABSTRACT— There is a marked lack of consensus concerning the best way to learn how conscious experiences arise. In this article, we advocate for scientific approaches that attempt to bring together four types of phenomena and their corresponding theoretical accounts: behavioral acts, cognitive events, neural events, and subjective experience. We propose that the key challenge is to comprehensively specify the relationships among these four facets of the problem of understanding consciousness without excluding any facet. Although other perspectives on consciousness can also be informative, combining these four perspectives could lead to significant progress in explaining a conscious experience such as remembering. We summarize some relevant findings from cognitive neuroscience investigations of the conscious experience of memory retrieval and of memory behaviors that transpire in the absence of the awareness of remembering. These examples illustrate suitable scientific strategies for making progress in understanding consciousness by developing and testing theories that connect the behavioral expression of recall and recognition, the requisite cognitive transactions, the neural events that make remembering possible, and the awareness of remembering.     

Symbolic magnitude processing in elementary school children: A group administered paper-and-pencil measure (SYMP Test)

The ability to compare symbolic numerical magnitudes correlates with children’s concurrent and future mathematics achievement. We developed and evaluated a quick timed paper-and-pencil measure that can easily be used, for example in large-scale research, in which children have to cross out the numerically larger of two Arabic one- and two-digit numbers (SYMP Test). We investigated performance on this test in 1,588 primary school children (Grades 1–6) and examined in each grade its associations with mathematics achievement. The SYMP Test had satisfactory test-retest reliability. The SYMP Test showed significant and stable correlations with mathematics achievement for both one-digit and two-digit comparison, across all grades. This replicates the previously observed association between symbolic numerical magnitude processing and mathematics achievement, but extends it by showing that the association is observed in all grades in primary education and occurs for single- as well as multi-digit processing. Children with mathematical learning difficulties performed significantly lower on one-digit comparison and two-digit comparison in all grades. This all suggests satisfactory construct and criterion-related validity of the SYMP Test, which can be used in research, when performing large-scale (intervention) studies, and by practitioners, as screening measure to identify children at risk for mathematical difficulties or dyscalculia.     

Anorexia and depression: depressive comorbidity in anorexic adolescents

Frequently, depression is a concomitant pathology in anorexia nervosa. To verify this, we carried out a comparative case/control study with 50 anorexic patients, restricting-type (ANP), 50 depressed patients (DP) and 50 non-patients (NP), aged between 13 and 16. We used the Rorschach Test and the Minnesota Multiphasic Personality Inventory (MMPI) and compared the results to parent's observations collected from the Achenbach Child Behavior Checklist (CBCL). Results showed two clearly different groups among participants: ANP with depression (36%) and ANP without depression (64%). This seems to indicate that depression is not a core element in anorexic disorders. However, we also observed a significant increase in the MMPI scale 2, which was probably related to starvation and weight loss. We confirmed the absence of general anxiety in the ANP group and obtained differences between depressive symptoms and those derived from coping deficit disorders. The discussion emphasizes the importance of using several tests to reduce bias in results and conclusions.     

Cross-cultural investigation of the Questionnaire of Smoking Urges in American and Spanish smokers

This study evaluated the factor structure of the Questionnaire of Smoking Urges (QSU) across American and Spanish smokers. Using confirmatory factor analyses, the fits of one-, two-, and four-factor models of smoking craving in American and Spanish data sets were compared. The two-factor model provided the best fit in both samples. However, negatively worded items confounded the interpretation of the two-factor structure in both the American and Spanish data. The first factor had positively and negatively worded items, whereas the second had only positively worded items. The two-factor structure was reexamined, removing either the positively or the negatively worded items. Using only positively worded items resulted in a loss of fit, whereas using only negatively worded items improved model fit substantially. Thus, the results supported the generalization of smoking craving across Spanish and American smokers and suggested that negatively worded items play a larger role in the two-factor structure of the QSU than originally thought.     

Working memory effects in speeded RSVP tasks

The present paper examines the effects of memory contents and memory load in rapid serial visual presentation (RSVP) speeded tasks, trying to explain previous inconsistent results. We used a one target (Experiment 1) and a two-target (Experiment 2) RSVP task with a concurrent memory load of one or four items, in a dual-task paradigm. A relation between material in working memory and the target in the RSVP impaired the identification of the target. In Experiments 3 and 4, the single task was to determine whether any information in memory matched the target in the RSVP, while varying the memory load. A match was detected faster than a non-match, although only when there was some distance between targets in the RSVP (Experiment 4). The results suggest that memory contents automatically capture attention, slowing processing when the memory contents are irrelevant to the task, and speeding processing when they are relevant.     

Cognitive Vulnerability to Emotional Symptoms: Reconsidering the Role of Worry and Rumination

The present study explored the pathways whereby cognitive variables (worry, rumination) may explain the relation between neuroticism and emotional symptoms in a community sample of adults (N?=?499). All participants completed a battery of questionnaires including measures of neuroticism, worry, rumination, anxiety and depression. Multiple mediation and moderated mediation analyses were used. Worry was a common pathway explaining the effect of neuroticism on both anxiety and depressive symptoms. The brooding subtype of rumination significantly mediated the relation between neuroticism and anxiety symptoms, but the reflection subtype did not have a mediating effect. Although worry by itself mediated the association between neuroticism and anxiety symptoms, it required a certain level of brooding to exert its mediating effect on the relation between neuroticism and depressive symptoms. The results are discussed in light of previous research and recent developments in treatment. Clinical implications and suggestions for future research are also discussed.     

Moderating Role of the Experience of having had a Female Boss in Relationship between Neosexism and Unfavorable Attitudes toward Female Leaders

Modern sexist beliefs are currently emerging as one of the most important barriers to achieving gender equality in managerial positions in organizations. However, little research addresses the factors that can reduce or soften the negative effects that these beliefs have on unfavorable attitudes toward female leaders. In the present study, it is analyzed whether the experience of having a female leader moderates this relationship. Additionally, we sought to verify whether this moderation is found in both genders. A sample of 307 employees from various positions in Spanish companies participated in this study. We performed regression analyses in blocks. The results indicate that this moderating role emerges only among women. Nevertheless, the findings also indicate that coming into contact with female leaders can increase these attitudes when the level of neosexism is low. The results suggest that the organizational policies that are introduced with the aim of reducing unfavorable attitudes and discriminatory behaviors toward female leaders should take into account that the assignment of women to leadership positions may favor the achievement of this aim in, at least, female employees who highly adhere to neosexist beliefs. However, this could also lead to an increase of these attitudes in female employees who present a low adherence to them.     

Negative work reflection,personal resources,and work engagement: the moderating role of perceived organizational support

This day-level study examined the role of perceived organizational support (POS) in the context of employees’ negative work reflection during off-job time. We hypothesized that negative work reflection during off-job time should be indirectly related to reduced work engagement on the next workday through personal resources (i.e., vigour and self-efficacy) in the morning. In addition, we hypothesized that POS moderated the relationships between negative work reflection and personal resources and between personal resources and work engagement. In total, 100 employees completed one general survey and three daily surveys (in the morning, after work, and at bedtime) over five workdays. Results of multilevel path analyses showed that negative work reflection was neither directly associated with personal resources nor indirectly with work engagement via personal resources, although vigour and self-efficacy positively predicted increased work engagement. However, negative work reflection was negatively associated with self-efficacy when POS was low. POS did not predict work engagement, but moderated the relationships between personal resources and work engagement: Consistent with the resource substitution hypothesis, high levels of POS compensated for low levels of vigour and self-efficacy. Negative work reflection had a significant negative indirect effect on work engagement through self-efficacy only when POS was low.     

Handwriting or Typewriting? The Influence of Pen- or Keyboard-Based Writing Training on Reading and Writing Performance in Preschool Children

Digital writing devices associated with the use of computers, tablet PCs, or mobile phones are increasingly replacing writing by hand. It is, however, controversially discussed how writing modes influence reading and writing performance in children at the start of literacy. On the one hand, the easiness of typing on digital devices may accelerate reading and writing in young children, who have less developed sensory-motor skills. On the other hand, the meaningful coupling between action and perception during handwriting, which establishes sensory-motor memory traces, could facilitate written language acquisition. In order to decide between these theoretical alternatives, for the present study, we developed an intense training program for preschool children attending the German kindergarten with 16 training sessions. Using closely matched letter learning games, eight letters of the German alphabet were trained either by handwriting with a pen on a sheet of paper or by typing on a computer keyboard. Letter recognition, naming, and writing performance as well as word reading and writing performance were assessed. Results did not indicate a superiority of typing training over handwriting training in any of these tasks. In contrast, handwriting training was superior to typing training in word writing, and, as a tendency, in word reading. The results of our study, therefore, support theories of action-perception coupling assuming a facilitatory influence of sensory-motor representations established during handwriting on reading and writing.     

Knockdown of Nurr1 in the rat hippocampus: implications to spatial discrimination learning and memory

Nurr1 expression is up-regulated in the brain following associative learning experiences, but its relevance to cognitive processes remains unclear. In these studies, rats initially received bilateral hippocampal infusions of control or antisense oligodeoxynucleotides (ODNs) 1 h prior to training in a holeboard spatial discrimination task. Such pre-training infusions of nurr1 antisense ODNs caused a moderate effect in learning the task and also impaired LTM tested 7 d later. In a second experiment, ODN infusions were given immediately after the animals had received two sessions of training, during which all animals showed normal learning. Although antisense treated rats were significantly impaired during the post-infusion stages of acquisition of the task, no group differences were observed during the LTM test given 7 d later. These animals were subjected 3 d later to reversal training in the same maze in the absence of any additional treatments. Remarkably, rats previously treated with antisense ODNs displayed perseveration: The animals were fixated with the previously learned pattern of baited holes, causing them to be significantly impaired in the extinction of acquired spatial preferences and future learning. We postulate that Nurr1 function in the hippocampus is important for normal cognitive processes.
