Training the equidistant principle of number line spacing

The characteristics of effective numerical trainings are still under scientific debate. Given the importance of number line estimation due to the strong relation between task performance and arithmetic abilities, the current study aimed at training one important number line characteristic: the equidistant spacing of adjacent numbers. Following an embodied training approach, second-graders were trained using a randomized crossover design to divide a presented line into different numbers of equal segments by walking the line with equally spaced steps. Performance was recorded, and feedback as to the correct equidistant spacing was provided using the Kinect sensor system. Training effects were compared to a control training with no involvement of task-specific whole-body movements. Results indicated more pronounced specific training effects after the embodied training. Moreover, transfer effects to number line estimation and arithmetic performance were partially observed. In particular, differential training effects for bounded versus unbounded number line estimation corroborate the assumption that not only bodily experiences but also the need for a flexible adaption of the perspective on the training material might influence training success. Hence, more pronounced training effects of the embodied training might stem from different cognitive processes involved.     

The Hong Kong version of the Oxford Cognitive Screen (HK-OCS): validation study for Cantonese-speaking chronic stroke survivors

This study reports the validation of the Hong Kong version of Oxford Cognitive Screen (HK-OCS). Seventy Cantonese-speaking healthy individuals participated to establish normative data and 46 chronic stroke survivors were assessed using the HK-OCS, Albert’s Test of Visual Neglect, short test of gestural production, and Hong Kong version of the following assessments: Western Aphasia Battery, MMSE, MoCA, Modified Barthel Index, and Lawton Instrumental Activities of Daily Living scale. The validity of the HK-OCS was appraised by the difference between the two participant groups. Neurologically unimpaired individuals performed significantly better than stroke survivors on the HK-OCS. Positive and significant correlations found between cognitive subtests in the HK-OCS and related assessments indicated good concurrent validity. Excellent intra-rater and inter-rater reliabilities, fair test–retest reliability, and acceptable internal consistency suggested that the HK-OCS had good reliability. Specific HK-OCS subtests including semantics, episodic memory, number writing, and orientation were the best predictors of functional outcomes.     

Wisdom and Psychosocial Functioning in Later Life

We investigated the connection between wisdom‐related performance, personality, and generativity to further the understanding of how they are interrelated. Our sample consisted of 163 men and women 68–77 years of age, mostly White, and predominantly middle class. Wisdom was assessed with the performance‐based Berlin Wisdom Paradigm, with the remaining measures being mostly self‐report. As hypothesized, on the zero‐order level, wisdom‐related performance (WRP) was positively associated with (a) growth, a personality component indexed by Openness to Experience, psychological mindedness, and a sense of well‐being derived from growth, purpose in life, and autonomy; (b) adjustment, a personality component associated with life satisfaction, high levels of Agreeableness and Conscientiousness, low Neuroticism, a sense of well‐being derived from positive relations with others, self‐acceptance, and environmental mastery; and (c) a generative concern for the welfare of others. Latent path analysis indicated that the bivariate associations between adjustment and wisdom and between generativity and wisdom were mediated by growth. Wise individuals are characterized by their ability to balance different personal strengths and interests, an integration that occurs, however, within the context of a dominant personality style marked by the pursuit of maturity through personal growth.     

Knowing Your Ability

In this article, we present an attempt to reconcile intellectualism and the anti‐intellectualist ability account of knowledge‐how by reducing “S knows how to F” to, roughly speaking, “S knows that she has the ability to F demonstrated by a concrete way w.” More precisely, “S has a certain ability” is further formalized as the proposition that S can guarantee a certain goal by a concrete way w of some method under some precondition. Having the knowledge of our own ability, we can plan our future actions accordingly, which would not be possible by merely having the ability without knowing it, and this pinpoints the crucial difference between knowledge‐how and ability. Our semi‐formal account avoids most of the objections to both intellectualism and the anti‐intellectualist ability account, and provides a multistage learning process of knowledge‐how, which reveals various subtleties.     

Does Parental Relational Aggression Interact with Parental Psychological Control in the Prediction of Youth Relational Aggression?

In a sample of 117 youth and their parents, the associations between parental relational aggression, psychological control, youth gender, and youth relational aggression were examined. Boys with parents high on relational aggression and psychological control reported more relational aggression than boys with parents high on relational aggression and low on psychological control. Girls with parents low on relational aggression and high on psychological control reported more relational aggression than girls with parents low on relational aggression and psychological control. Results indicate youth may learn to use relational aggression from their parents, and have implications for intervention with relationally aggressive youth.     

Rumination and self-defining memories in the context of health concerns

Individuals with health anxiety report experiencing a strong sense of vulnerability to illness. Such beliefs may be driven by the biased recollection of past illness-related events. However, little research has explored the role of memory in health anxiety. In other disorders, rumination has also been identified as a process that leads individuals to recall memories dominated by the content of their concerns. This study examined the proposition that rumination might impact the content of “self-defining” autobiographical memories among 60 college students with varying health anxiety (35% with clinical-level health anxiety). Participants were randomised to experiential/ruminative self-focus conditions, and then they completed the Self-Defining Memory Task. Responses were coded for valence and illness-relatedness. Results indicated that rumination led participants to retrieve more illness-related self-defining memories, while higher health anxiety scores were associated with more negative, but not more illness-focused memories. Ruminative thinking appears to activate health concerns, and may play a role in maintaining ongoing health anxiety.     

Examining and reexamining the structure of Chinese-English bilingual memory

The asymmetry model of bilingual memory proposed by Kroll and Stewart assumes that translation from a first language (L1) into a second language (L2), or forward translation, is mediated by an underlying conceptual memory, whereas L2-to-L1, or backward, translation is lexical and direct. Lexical links from L2 to L1 are hypothesized to be stronger than those from L1 to L2, but conceptual links are stronger for L1 than L2. These assumptions were evaluated in this study, which used stimulus items with similar recognition thresholds. Proficient Chinese-English bilinguals were tested on picture naming, word naming, word translation and category matching. The translation asymmetry effect predicted by the model (i.e., backward being faster than forward translation) was demonstrated; matching an L1 item to a category name was also faster than matching an L2 item. This pattern of results, nevertheless, did not completely hold after an adjustment procedure which sought to control for variations in response production and concept retrieval times due to stimulus types. The present findings are consistent with previous ones which show increased L2 conceptual processing for the proficient bilingual. They also suggest that an extended version of the asymmetry model should take into account possible biasing effects associated with some conventionally used bilingual tasks.     

Remembering in signs

In a short-term memory experiment, signs of American Sign Language in list lengths of three to seven items were presented to deaf college students whose native language is American Sign Language. A comparable short-term memory experiment for words (words representing the English translation-equivalents of the signs) was presented to hearing college students. Recall was written, immediate and ordered. Overall, short-term memory mechanisms in the deaf seem to parallel those found in hearing subjects, even with the modality change. A significant number of multiple intrusion errors made by deaf subjects to signs were based on formational properties of the signs themselves, a result paralleling the phonologically based errors in experiments with hearing subjects.Our results are consistent with a theory that the signs of American Sign Language are actually coded by the deaf in terms of simultaneous formational parameters such as Hand Configuration, Place of Articulation and Movement. Evidence is given that signs are treated by the deaf as consisting of independent parameters — specific to American Sign Language — which are essentially arbitrary in terms of meaning.
